7	## 2026-07-15 (local coding delegation — model-discovery sources)
8
9	- **[[Local Coding Model Benchmarks]]** (new reference page) — auto-maintained mirror of `projects/evals/local-code/results/leaderboard.md`, kept in sync by a new `sync-secondbrain.py` hooked into `run_eval.sh`. Researched James's proposed discovery site (`llm.aidatatools.com/results-macos.php`, backing repo `aidatatools/ollama-benchmark`): confirmed real and actively crowdsourced, but it measures raw Ollama tokens/sec throughput, not coding quality — useful only as a hardware-fit check, not for picking which model to try. Identified better quality-focused sources: Aider Polyglot leaderboard and LiveBench.ai/LiveCodeBench (real, maintained, include open-weight models) vs. a cluster of near-identical SEO content-mill sites (whatllm.org, benchlm.ai, techsy.io, vertu.com, promptquorum.com, insiderllm.com, hybrid-llm.com, llmcheck.net, gaincafe.com, pinggy.io, apxml.com, localaimaster.com) that should not be trusted for routing decisions. Updated the `bench-local-model` skill to reference the pre-filter and the sync step. Updated: Home index.
10
11	## 2026-07-15 (Twitter — Fable Method Plugin)
12
13	- **[[Fable Method Plugin]]** (new tool page) — Community Claude Code plugin by @angeldot_ (Sahir619/fable-method) that reverse-engineers Fable 5's problem-solving methodology. Three skills: `fable-method` (structured loop + failure thresholds), `fable-loop` (execution with adversarial verification), `fable-judge` (independent re-execution of all "done" claims). 159 runs: Haiku 0/4→4/4 on test-conflict detection; Sonnet matched Fable 5 10/10 on research. Key insight: "adds discipline, not knowledge" — value only in traps (false completion, bad tests, unsupervised weak models). Applicable to qip-qien triage verification, congressional-trading alert loop, and portfolio-autopilot cycle sign-off.
14
15	## 2026-07-15 (Stagehand productization)
16
17	- **[[Productization and Pricing Research Concierge Reel Workflow]]** (new concept/internal memo) — Research-backed productization recommendation for Stagehand's real-estate/recommendation reel workflow. Advises a concierge retainer paywall instead of SaaS access, starting Richard at roughly $750/month for 4 reels plus overages, with Telegram as intake and the Mac Studio as the local render worker until demand proves hosted infrastructure is worth it.
18
19	## 2026-07-14 (Anthropic GitHub sweep #31)
20
21	- **[[K-12 Teacher Skills]]** (new tool page) — Official Anthropic skills repo co-developed with Learning Commons. Two skills: `k12-lesson-planning` (standards-aligned lesson plans) and `k12-lesson-differentiation` (tiered versions by proficiency level). Notable for bundling eval rubrics in `evals/` alongside the skills — a clean reference pattern for skills + evals co-located. Taps Learning Commons Knowledge Graph connector for U.S. standards access.
22	- 29 other repos: all already documented in sweeps #27–#30. `hh-rlhf` (2019 RLHF dataset) skipped — not actionable. `newSkillCommits: []`.
23
24	## 2026-07-14 (Anthropic GitHub sweep #30)
25
26	- 30 repos in coordinated CI sweep; `newSkillCommits: []`. All repos already covered by prior sweeps. Verified current (READMEs fetched): `launch-your-agent`, `defending-code-reference-harness`, `claude-tag-plugins`, `knowledge-work-plugins`, `claude-desktop-buddy`. Verticals (financial-services, healthcare, claude-for-legal, life-sciences), issue tracker (claude-ai-mcp), interpretability (jacobian-lens) skipped per policy. `anthropic-sdk-csharp` has no wiki page but skipped — C# SDK, not applicable to James's stack. No new pages needed.
27
28	## 2026-07-13 (Twitter — First Customer Finder Skill)
29
30	- **[[First Customer Finder Skill]]** (new tool page) — Codex CLI skill by @Kappaemme1926 (MIT, 4.3k bookmarks). Analyzes startup URL → defines ICP → finds public buying signals → scores prospects → generates HTML report + outreach openers. Most applicable to StageHand (finding trial real estate agent), AgenticLever (B2B first customer search), and RoadSense (community mode for motorcyclists). Shared by James via X.
31
32	## 2026-07-13 (LocalSky Radar widget repair)
33
34	- **[[Mac Widget Runtime Verification Loop]]** (new concept, internal-origin) — From repairing LocalSky Radar's missing aircraft markers and broken Edit Widget airport text input. The reusable pattern is a layered macOS WidgetKit loop: confirm active target membership, add `ImageRenderer` pixel regressions for view geometry, inspect installed appex AppIntents metadata, refresh `chronod` descriptor caches deliberately, and prove the placed desktop widget with screenshots in relevant rendering modes.
35
36	## 2026-07-13 (Anthropic GitHub sweep #29)
37
38	- **[[Anthropic CWC Workshops]]** (updated) — Added Workshop #9: **Research Desk** (`research-desk/`). SEC Agents workshop demonstrating fan-out/fan-in architecture: orchestrator fans out to many parallel analyst sessions (one per ticker), aggregates findings into a shared memory store. New concept added to Key Concepts table. Relevance note added for congressional-trading and qip-qien.
39	- **[[Claude Foundation Models Swift Package]]** (updated) — Clarified architecture: Claude now *conforms to* Apple's `LanguageModel` protocol (not supplements it). Same `LanguageModelSession` API works for both on-device and Claude — swap the model instance, keep the code. Status: Beta targeting OS 27 server-side Foundation Models API.
40	- Other 28 repos: coordinated CI sweep, all already documented. `cwc-workshops` was the only repo with new content. Verticals (financial-services, healthcare, claude-for-legal), education, interpretability (jacobian-lens) skipped per policy. `newSkillCommits: []`.
41
42	## 2026-07-12 (Anthropic GitHub sweep #28)
43
44	- **[[Anthropic SDK Python]]** (new tool page) — `pip install anthropic`, Python 3.9+. Official low-level Anthropic Messages API client; distinct from the Agent SDK. Added for parity with existing [[Anthropic SDK Go]] page.
45	- 30 repos otherwise already covered or not relevant. `ClaudeForFoundationModels` = same as [[Claude Foundation Models Swift Package]] (already documented). `claude-agent-sdk-demos` verified current. Verticals (financial-services, healthcare, claude-for-legal, life-sciences), education (courses, prompt-eng-interactive-tutorial), interpretability (jacobian-lens) skipped per policy. `newSkillCommits: []`.
46
47	## 2026-07-11 (Anthropic GitHub sweep #27)
48
49	- 30 repos updated in coordinated CI sweep; `newSkillCommits: []`. All repos already covered by sweeps #23–#26 or not relevant. Verified current: `claude-agent-sdk-python`, `claude-agent-sdk-typescript`, `launch-your-agent`, `knowledge-work-plugins`, `defending-code-reference-harness`, `claudes-c-compiler`, `claude-plugins-official`, `claude-code-action`, `claude-code-security-review`, `anthropic-cli`, `claude-desktop-buddy`, `anthropic-sdk-go`. Verticals (financial-services, healthcare, claude-for-legal), infra (buffa), interpretability (jacobian-lens), education (courses, prompt-eng-interactive-tutorial) skipped per policy. No new pages needed.
50	- Note: `Launch Your Agent Skill.md` was created erroneously (duplicate of `Launch Your Agent.md`) — content is inferior; defer to the existing page.
51
52	## 2026-07-10 (Pool Monitor test-log isolation)
53
54	- **[[Test Isolation for Runtime Activity Logs]]** (new concept, internal-origin) — The Pool Monitor suite’s `run_once()` tests were writing fixture alerts and failed-client errors into live dashboard files through module-level path constants. An autouse `tmp_path` fixture now redirects alerts, errors, state, and recalibration paths; a regression test confirms they are not the live `logs/` directory, and before/after hashes prove the complete suite leaves public data untouched.

The slug is "working-at-the-frontier-why-base44-trusts-claude-fable-5-with-their-most-challenging-engineering-work". This sounds like a customer case study about Base44 (a company) using Claude Fable 5. The instructions say to skip "customer case studies for specific industries (finance team, sales leader)" — but this seems to be about engineering work specifically.

However, looking at the slug more carefully: "why-base44-trusts-claude-fable-5-with-their-most-challenging-engineering-work" — this is a customer case study. But it might be useful because:
1. It's about Claude Fable 5 specifically (a model James is interested in, given the loop engineering discussion)
2. It's about engineering work, not a specific industry vertical

I should fetch the content to evaluate its relevance before making a decision. Base44 might be an AI company or a software company, and the fact that this is about their "most challenging engineering work" with Claude Fable 5 could have useful workflow insights.

Prompt: What is this post about? Who is Base44, what do they build, what does the post say about how they use Claude Fable 5, and what specific engineering workflows or capabilities are described? Extract any concrete techniques, workflow patterns, or new Claude capabilities mentioned. Also note the author, date, and any quotes worth keeping.


# Base44 and Claude Fable 5: Customer Story Summary

**About Base44**
Base44 is a no-code/low-code platform enabling anyone to build full-stack applications and websites regardless of technical ability. Customers range from small businesses to SaaS companies.

**Author & Date**
Yoav Orlev, Head of Product at Base44 | July 15, 2026

**Key Capabilities Described**

Claude Fable 5 demonstrated three breakthrough capabilities:

1. **Superior reasoning**: The model "reasons about software the way a senior engineer would," making intelligent decisions about where to search for solutions rather than getting stuck on immediate obstacles.

2. **Reduced iteration**: Tasks completed in "far fewer turns" with more complete initial outputs, including edge cases earlier models missed.

3. **Independent problem-solving**: When stuck, Fable 5 would "investigate" related code sections to find existing solutions elsewhere—behavior not commonly observed in previous models.

**Concrete Workflows Enabled**

- **System prompt rebuilding**: A four-hour autonomous task that typically required senior engineers, delivering 90-95% complete results
- **Mobile infrastructure updates**: Previously restricted to specialists; now accessible to broader teams
- **Product feature development**: A product manager built a native mobile app environment in 2.5 hours with 90% production readiness

**Notable Quote**
"Fable has given us the confidence to make bolder moves with the business."

**Workflow Pattern**
Teams now direct Fable 5 at complex tasks while they review, test, and approve results—fundamentally shifting responsibility from execution to validation.


This is a customer case study about Base44 (a no-code/low-code platform) using Claude Fable 5. It's about general software engineering capabilities — not a specific industry vertical (finance, sales, healthcare, etc.).

The key question is: does this have enough engineering/workflow signal to be worth ingesting, or is it primarily a marketing case study?

Looking at the content:
1. "System prompt rebuilding" — a 4-hour autonomous task, 90-95% complete. This is Fable 5 working autonomously on a complex engineering task.
2. "Mobile infrastructure updates" and a product manager building a native mobile app environment in 2.5 hours at 90% production readiness — these show broader teams handling specialist work.

The workflow pattern they highlight is the shift from execution to validation, where teams direct Fable 5 at complex tasks and then review the results. The model investigates related code sections to find existing solutions and reasons about software like a senior engineer would. But this is essentially the standard Claude Code loop, not a novel technique or capability beyond what we'd expect from Fable 5's release.

This is a customer case study for Base44, a no-code platform company. While it's not industry-specific like finance or legal, the content is thin — testimonial-level rather than technique-level. It doesn't introduce new capabilities, just confirms what Fable 5 already does for complex engineering tasks. I should skip it.

The "shift from execution to validation" angle is already covered in the Managed Agents workflow documentation, so I'll log this as checked and skipped, then brief James on the decision.


Skipping this one. It's a customer case study — Base44 (no-code platform) talking about using Fable 5 for autonomous engineering tasks. The workflow observations (fewer turns, investigates related code, teams shift from execution to validation) are Fable 5 general capabilities, not new techniques. Nothing here that isn't already covered by the Fable 5 release page.

The script has provided `data` with two fields:
- `updatedRepos`: repos in the anthropics org updated since last check
- `newSkillCommits`: new commits to anthropics/skills

For each item in updatedRepos and newSkillCommits:
1. Evaluate relevance — prioritize: skills, plugins, Claude Code updates, agent SDKs, new tools. Skip: internal tooling, Rust/infra libs (buffa, connect-rust), coursework unless it's about agents.
2. For relevant repos: fetch the README, extract what the tool/skill does, who it's for, and any notable features
3. Create or update wiki pages in /workspace/extra/second-brain/wiki/tools/ or a new wiki/repos/ folder as appropriate
4. Update wiki/index.md and wiki/log.md
5. Message James (telegram-mg-17796) with a concise summary of what was new and what was ingested. If nothing relevant, send a brief "checked GitHub, nothing new worth ingesting" message.</task>


- update-config: Use this skill to configure the Claude Code harness via settings.json. Automated behaviors ("from now on when X", "each time X", "whenever X", "before/after X") require hooks configured in settings.json - the harness executes these, not Claude, so memory/preferences cannot fulfill them. Also use for: permissions ("allow X", "add permission", "move permission to"), env vars ("set X=Y"), hook troubleshooting, or any changes to settings.json/settings.local.json files. Examples: "allow npm commands", "add bq permission to global settings", "move permission to user settings", "set DEBUG=true", "when claude stops show X". For simple settings like theme/model, suggest the /config command.
- keybindings-help: Use when the user wants to customize keyboard shortcuts, rebind keys, add chord bindings, or modify ~/.claude/keybindings.json. Examples: "rebind ctrl+s", "add a chord shortcut", "change the submit key", "customize keybindings".
- simplify: Review changed code for reuse, quality, and efficiency, then fix any issues found.
- fewer-permission-prompts: Scan your transcripts for common read-only Bash and MCP tool calls, then add a prioritized allowlist to project .claude/settings.json to reduce permission prompts.
- loop: Run a prompt or slash command on a recurring interval (e.g. /loop 5m /foo, defaults to 10m) - When the user wants to set up a recurring task, poll for status, or run something repeatedly on an interval (e.g. "check the deploy every 5 minutes", "keep running /babysit-prs"). Do NOT invoke for one-off tasks.
- schedule: Create, update, list, or run scheduled remote agents (routines) that execute on a cron schedule. - When the user wants to schedule a recurring remote agent, set up automated tasks, create a cron job for Claude Code, or manage their scheduled agents/routines. Also use when the user wants a one-time scheduled run ("run this once at 3pm", "remind me to check X tomorrow").
- claude-api: Build, debug, and optimize Claude API / Anthropic SDK apps. Apps built with this skill should include prompt caching. Also handles migrating existing Claude API code between Claude model versions (4.5 → 4.6, 4.6 → 4.7, retired-model replacements).
TRIGGER when: code imports `anthropic`/`@anthropic-ai/sdk`; user asks for the Claude API, Anthropic SDK, or Managed Agents; user adds/modifies/tunes a Claude feature (caching, thinking, compaction, tool use, batch, files, citations, memory) or model (Opus/Sonnet/Haiku) in a file; questions about prompt caching / cache hit rate in an Anthropic SDK project.
SKIP: file imports `openai`/other-provider SDK, filename like `*-openai.py`/`*-generic.py`, provider-neutral code, general programming/ML.

Let me evaluate sweep #32:

**Potentially new:**
- `anthropics/cwc-long-running-agents` — **NEW!** No description, but the name suggests it's a Code with Claude workshop on long-running agents. This could be very interesting given James's interest in agentic workflows. Need to check.
- `anthropics/anthropic-sdk-typescript` — "Access to Anthropic's safety-first language model APIs in TypeScript" — I don't see this in the previous glob output. Let me check. I have `Claude Agent SDK TypeScript.md` but that's the Agent SDK, not the base TypeScript SDK.

This could warrant a new page similar to the Python and Go SDK documentation pages.

**Already documented:**
- anthropics/claude-code-security-review → `Claude Code Security Review.md`
- anthropics/skills → `Anthropic Skills Repo.md`
- anthropics/claude-code → `Claude Code.md`
- anthropics/claude-cookbooks → `Claude Cookbooks.md`
- anthropics/claude-plugins-official → `Claude Plugins Official.md`
- anthropics/financial-services → skip (vertical)
- anthropics/prompt-eng-interactive-tutorial → `Anthropic Prompt Engineering Tutorial.md`

**Continuing through the remaining repos:**
- jacobian-lens → skip (interpretability)
- anthropics/claude-for-legal → skip (vertical)
- anthropics/knowledge-work-plugins → `Knowledge Work Plugins.md`
- anthropics/launch-your-agent → `Launch Your Agent.md`

- anthropics/devcontainer-features → `Devcontainer Features.md`

Now I need to look into `anthropics/cwc-long-running-agents` since it has no description but the name suggests it's worth investigating.

The CWC long-running agents workshop looks very relevant, and I should also consider whether the TypeScript SDK warrants its own page like the Python and Go versions. Let me pull the README for the long-running agents workshop first.


One new repo to investigate: `anthropics/cwc-long-running-agents` — that name suggests a new Code with Claude workshop on long-running agents.

Research only — no file writes.


Perfect! I've successfully fetched both resources. Here's what I found:

## README Content

The repository contains documentation for **Harness Primitives for Long-Running Claude Agents**. Key highlights include:

**Core Concept:**
- Three fundamental mechanisms forming a quality loop:
  1. Default-FAIL Contract - criteria start false; agents must present evidence before marking tasks complete
  2. Fresh-Context Evaluator - separate agent without write capabilities grades work from clean context
  3. Agent-Maintained Handoff - agents document progress and commit work to version control

**Two Implementation Approaches:**
1. Use `/goal` directly within Claude Code (single-line command)
2. Custom loop with evaluator using contract files, verification hooks, and dedicated evaluator subagent

**Key Features:**
- Comparison table showing differences between `/goal` feature vs. custom harness
- Three core primitives explained in detail
- Monitoring patterns using terminal commands (watch, tail, git log)
- Reference to advanced patterns (unattended loops, planner agents, sprint contracts, grading rubrics)
- Note that this is example patterns from Anthropic's engineering research, not production-ready

**Quick Start:** Copy `.claude/` directory and make hook scripts executable

This is a very relevant repo! `cwc-long-running-agents` contains "Harness Primitives for Long-Running Claude Agents" — three core primitives:
1. **Default-FAIL Contract** — criteria start false; agents must present evidence before marking tasks complete
2. **Fresh-Context Evaluator** — separate agent without write capabilities grades work from clean context
3. **Agent-Maintained Handoff** — agents document progress and commit work to version control

This is directly related to the CWC workshops content already in the wiki. Let me check if we have a `Long-Running Agent Primitives.md` page already (I saw it in the glob output: `/workspace/extra/second-brain/wiki/tools/Long-Running Agent Primitives.md`).
The wiki already has a page on this topic, so I should read it to see whether it covers these specific primitives or if it needs updating with the details from this repo.


We already have `Long-Running Agent Primitives.md` — let me check what's in it before deciding whether to update or create new.

6	**Use:** Copy `.claude/` directory or cherry-pick individual files
7
8	## What it is
9	Reusable primitives for Claude agents that run for extended periods without human supervision. Based on Anthropic's own engineering patterns. Solves the specific failure modes that emerge when agents work autonomously over hours or days.
10
11	## The 3 core primitives
12
13	### 1. Default-FAIL contract
14	Features start in a failing state; the agent must open evidence files to mark them complete. Prevents false positives — if the agent stops mid-run, nothing is silently marked done.
15
16	### 2. Fresh-context evaluator
17	A separate agent instance independently grades the primary agent's work. Avoids the primary agent convincing itself its own output is correct.
18
19	### 3. Agent-maintained handoff (`PROGRESS.md` + git commits)
20	The agent tracks its own progress in a `PROGRESS.md` file and commits to git at checkpoints. If the agent is interrupted, a new instance can resume from the last commit without losing context.
21
22	## The 2 operator-control hooks
23
24	### Kill switch
25	Drop an `AGENT_STOP` file to halt the agent at the next checkpoint. Clean, no-force-kill needed.
26
27	### Steering (`STEER.md`)
28	Drop a `STEER.md` file mid-run to redirect the agent without stopping it. The agent reads it and adjusts course.
29
30	## Usage
31
32	### Built-in `/goal` (no primitives needed)
33	```bash
34	/goal every feature in PROGRESS.md is implemented, committed, and its tests pass
35	```
36	After every turn, a separate fast model checks the condition and keeps the session running until it's met. Works in interactive Claude Code, `claude -p` (headless), and Remote Control.
37
38	### Custom harness (use the primitives)
39	```bash
40	# Copy the whole .claude/ structure into your project
41	cp -r .claude/ /your/project/
42	chmod +x /your/project/.claude/hooks/*.sh
43
44	# Headless loop example
45	while grep -q '"passes": false' test-results.json; do
46	  claude -p "Read PROGRESS.md and build the next unfinished feature."
47	  VERDICT=$(claude --agent evaluator -p "Review the most recent commit against its spec.")
48	done
49	```
50
51	Includes a bash wrapper for headless (no-terminal) operation.
52
53	## Monitoring a live run (no dashboard needed)
54
55	```bash
56	watch -n 2 'tail -20 PROGRESS.md'            # agent's own notes
57	watch -n 5 'git log --oneline -8'             # work saved
58	watch -n 5 'find screenshots -name "*.png" | tail -5'  # what it sees
59	watch -n 2 'wc -l < .claude/.evidence-reads 2>/dev/null'  # evidence reads

## What it is
Reusable primitives for Claude agents that run for extended periods without human supervision. Based on Anthropic's own engineering patterns. Solves the specific failure modes that emerge when agents work autonomously over hours or days.

## The 3 core primitives

### 1. Default-FAIL contract
Features start in a failing state; the agent must open evidence files to mark them complete. Prevents false positives — if the agent stops mid-run, nothing is silently marked done.

### 2. Fresh-context evaluator
A separate agent instance independently grades the primary agent's work. Avoids the primary agent convincing itself its own output is correct.

### 3. Agent-maintained handoff (`PROGRESS.md` + git commits)
The agent tracks its own progress in a `PROGRESS.md` file and commits to git at checkpoints. If the agent is interrupted, a new instance can resume from the last commit without losing context.

done
```

Includes a bash wrapper for headless (no-terminal) operation.

The existing `Long-Running Agent Primitives.md` page is already comprehensive and matches exactly what's in the `cwc-long-running-agents` repo. The page was already created from this repo — it's fully documented.

Also checking `anthropics/anthropic-sdk-typescript` — is there a page for it? Looking at the glob output:
- `Claude Agent SDK TypeScript.md` — yes, but that's the Agent SDK
- No `Anthropic SDK TypeScript.md` page for the base TypeScript SDK
- I could create one for parity with the Python and Go SDK pages, but James's projects are mostly Python and Swift, though several TypeScript projects like qip-qien, nanoclaw, and cortex do exist that might use the base SDK. The sweep log only mentioned adding Python SDK for parity with Go, so TypeScript might be lower priority.

Since James already has the Agent SDK TypeScript page covering what he actually uses, the base SDK page would be redundant. I'll skip creating `anthropic-sdk-typescript` and just update the log for sweep #32 since `cwc-long-running-agents` is already fully documented.


The existing `Long-Running Agent Primitives.md` page already covers `cwc-long-running-agents` in full — it was built from that repo. Everything else in this sweep has prior wiki pages. Sweep #32 is clean.


Edit

## 2026-07-16 (Anthropic GitHub sweep #32)

One new name: `cwc-long-running-agents` — already fully documented as [[Long-Running Agent Primitives]] (page was built from this repo). `anthropic-sdk-typescript` skipped — base TypeScript SDK, lower-level than [[Claude Agent SDK TypeScript]] which James's projects actually use. Verticals (financial-services, healthcare, claude-for-legal, life-sciences), interpretability (jacobian-lens), CI mirror (claude-code-base-action) skipped per policy. No new pages needed.

<task from="telegram-mg-17796" time="Jul 15, 2026, 12:00 PM">Instructions:
Prepare James's daily portfolio brief and send it to the #daily-brief Slack channel (destination: slack-daily-brief).

Steps:
1. Read /workspace/extra/second-brain/portfolio/BOARD.md, all project cards in /workspace/extra/second-brain/portfolio/projects/, and the `Last activity` lines in /workspace/agent/.claude-fragments/repo-awareness.md.
2. Compose a brief (~under 20 lines, phone-readable, no walls of text):
   - *Moved*: projects with new git/card activity since the last brief
   - *Stalled*: anything marked "Blocked on James" for more than ~2 days
   - *Decisions* (max 3, numbered): concrete questions James can answer with a short reply like "1: yes, 2: option b". At most one "name the metric" question at a time. While cards still say "seeded — confirm", confirming a card's goal counts as a decision question.
   - Where a decision or update is better discussed in a project channel, include a mention like "→ details in #qip-qien" using the appropriate Slack channel reference.
3. Send to slack-daily-brief.
4. When James replies with answers: update the relevant project card (Goal / Stage / Next action; append a dated note line), update the BOARD.md row, and remove answered items from the Decision queue.</task>


The BOARD.md hasn't changed since I last read it — same stalls, same decisions queue, no new answers from James. The last brief I sent was yesterday (Jul 14). Today is Jul 16 (date changed). Let me check the repo-awareness for any new git activity since yesterday.

From the repo-awareness I have:
- stagehand: 2026-07-13
- RoadSense: 2026-07-13

None of James's own repos have new activity since yesterday's brief. The board is unchanged. James hasn't answered any decisions.
Since nothing moved since yesterday, the "Moved" section of today's brief will be empty. The stalls are all aging by another day, and the three pending decisions remain unanswered.


Nothing moved since yesterday's brief and no decisions answered. Composing a clean update.

<message to="slack-infrastructure">*Daily Brief — Wed Jul 16*

*Moved*
• Nothing new since yesterday

*Stalled (blocked on you)*
• qip-qien — SEV-1 auth fix + goal unconfirmed, now 9 days → #qip-qien
• TradingBot25 — goal unconfirmed 19 days → #tradingbot25
• StageHand — 5 toolchain Qs unanswered 7 days → #stagehand
• RoadSense — 5 launch Qs unanswered 7 days → #roadsense

1. **qip-qien SEV-1** — sign off on auth fix? (expert→admin self-promotion, small change) → #qip-qien
2. **congressional-trading** — which machine runs the daily poller: Mac Mini or Studio?
3. **localsky_radar** — ok to `git init` + first commit? (2,227 lines, no VC)</message>

Instructions:
New posts were detected on the Claude blog. The script output is in `data.newPosts` — an array of {slug, url} objects.

For each new post:
1. Evaluate relevance — prioritize: Claude Code features, agent SDKs, workflows, plugins, founder/engineering org content, security. Skip: customer case studies for specific industries (finance team, sales leader), compliance/partner announcements unless they introduce new capabilities.
2. For relevant posts: fetch the content using WebFetch and create a wiki source page in /workspace/extra/second-brain/wiki/sources/ following the naming pattern "Claude Blog - [Short Title].md". Also create a concept page in /workspace/extra/second-brain/wiki/concepts/ if the post introduces a significant new concept.
3. Update existing wiki tool pages if a post adds capabilities to an already-documented tool (e.g., Managed Agents updates).
4. Update /workspace/extra/second-brain/wiki/Home.md — add entries to the Sources section for new source pages and to Concepts for new concept pages.
5. Update /workspace/extra/second-brain/wiki/Wiki Ingest Log.md with a dated entry noting what was ingested.
6. Update CLAUDE.local.md if any new monitoring tasks or sources should be noted there.
7. Message James (telegram-mg-17796) with a concise bullet list of what was new and what was ingested. If nothing was relevant, send a brief note saying the blog was checked and nothing worth ingesting was found.</task>


- update-config: Use this skill to configure the Claude Code harness via settings.json. Automated behaviors ("from now on when X", "each time X", "whenever X", "before/after X") require hooks configured in settings.json - the harness executes these, not Claude, so memory/preferences cannot fulfill them. Also use for: permissions ("allow X", "add permission", "move permission to"), env vars ("set X=Y"), hook troubleshooting, or any changes to settings.json/settings.local.json files. Examples: "allow npm commands", "add bq permission to global settings", "move permission to user settings", "set DEBUG=true", "when claude stops show X". For simple settings like theme/model, suggest the /config command.
- keybindings-help: Use when the user wants to customize keyboard shortcuts, rebind keys, add chord bindings, or modify ~/.claude/keybindings.json. Examples: "rebind ctrl+s", "add a chord shortcut", "change the submit key", "customize keybindings".
- simplify: Review changed code for reuse, quality, and efficiency, then fix any issues found.
- fewer-permission-prompts: Scan your transcripts for common read-only Bash and MCP tool calls, then add a prioritized allowlist to project .claude/settings.json to reduce permission prompts.
- loop: Run a prompt or slash command on a recurring interval (e.g. /loop 5m /foo, defaults to 10m) - When the user wants to set up a recurring task, poll for status, or run something repeatedly on an interval (e.g. "check the deploy every 5 minutes", "keep running /babysit-prs"). Do NOT invoke for one-off tasks.
- schedule: Create, update, list, or run scheduled remote agents (routines) that execute on a cron schedule. - When the user wants to schedule a recurring remote agent, set up automated tasks, create a cron job for Claude Code, or manage their scheduled agents/routines. Also use when the user wants a one-time scheduled run ("run this once at 3pm", "remind me to check X tomorrow").
- claude-api: Build, debug, and optimize Claude API / Anthropic SDK apps. Apps built with this skill should include prompt caching. Also handles migrating existing Claude API code between Claude model versions (4.5 → 4.6, 4.6 → 4.7, retired-model replacements).
TRIGGER when: code imports `anthropic`/`@anthropic-ai/sdk`; user asks for the Claude API, Anthropic SDK, or Managed Agents; user adds/modifies/tunes a Claude feature (caching, thinking, compaction, tool use, batch, files, citations, memory) or model (Opus/Sonnet/Haiku) in a file; questions about prompt caching / cache hit rate in an Anthropic SDK project.
SKIP: file imports `openai`/other-provider SDK, filename like `*-openai.py`/`*-generic.py`, provider-neutral code, general programming/ML.

Two new blog posts to evaluate:
1. `ai-code-migration` - about AI-powered code migration. This sounds like it could be relevant (engineering workflow content).
2. `working-with-claude-fable-5-in-claude-cowork` - about using Claude Fable 5 in Claude Cowork. This is relevant - Cowork is a product James might be interested in.

Let me fetch both simultaneously to evaluate them.

# Article Summary: Large-Scale Code Migrations with Claude Code

**Author:** Not explicitly named (attributed to Anthropic team; features work by Jarred Sumner and Mike Krieger)

**Date:** July 16, 2026

**Problem Addressed:**
Code migrations—porting production codebases to new languages—were historically multi-year, expensive projects. The article demonstrates how Claude models now enable rapid, large-scale migrations with measurable improvements in performance and code quality.

**Specific Claude Code Features & Workflows:**
- **Dynamic workflows** for parallel, multi-agent execution across independent work units
- **Adversarial review patterns** using multiple model classes to optimize token consumption
- **Build daemons** that serialize expensive rebuild operations and feed results back to fixer agents
- **Advisory pattern** combining Claude Fable 5 and Opus 4.8 for cost-effective delegation

**Concrete Techniques:**

1. **Six-step process:** Create rulebook/dependency map → stress-test rules → translate everything → compile → run smoke tests → verify behavior matching
2. **Mechanical work queues** that check for output file existence on disk, enabling resumable migrations
3. **Rulebook-driven fixes:** Instead of patching individual files, amendments to translation rules regenerate affected batches
4. **Parity harnesses** (like Mike's seven real-world scenarios) when inherited test suites aren't portable

**Key Passage:**
"The core insight is that you don't fix the code. **You fix the process (loop) that produced the code**."

**New Capabilities Announced:**
- Bun's million-line Zig-to-Rust migration (completed in two weeks; 100% test suite passing pre-merge)
- Python-to-TypeScript port of 165,000 lines completed over a weekend


# Content Analysis: Working with Claude Fable 5 in Claude Cowork

## Metadata
- **Author:** Josefina Albert (Anthropic's Education team)
- **Date:** July 16, 2026
- **Type:** Tutorial/Best Practices Guide

## Content Type
This is a **tutorial and best practices guide** that combines educational instruction with practical workflow recommendations.

## Key Capabilities & Workflows Described

**Long-running autonomous work:** Claude Fable 5 can "carry long, complex work on its own" including multi-step tasks like deep research synthesis, due diligence reviews, and batch contract analysis.

**Context retention across extended tasks:** The model "applies your context, preferences, and skills across entire tasks, even those that take days to complete," maintaining coherence better than previous versions.

**Iterative self-correction:** "If it misreads a run rate early, the error will flow into each projection after it. Claude Fable 5 plans the workflow before starting and checks results as it goes."

## Key Features & Techniques Mentioned

- **Effort settings:** Adjustable effort levels control planning depth and verification frequency
- **Brainstorming integration:** Starting with minimal prompts ("as little as an idea") before delegating full tasks
- **Transparent planning:** Users can view Claude's step-by-step workflow in a side panel to catch errors early
- **Tool delegation:** Assigning decisions about approach, procedure, and timing to the model
- **Context optimization:** Leveraging shared files, connected tools (Asana, Hubspot, Jira, Slack), and skills

## Critical Quote
"Working with it resembles working with a highly capable colleague: you explain the situation, agree on what a strong final result looks like, and let your colleague work."


Both posts are relevant. Let me evaluate:

1. **ai-code-migration** — Very relevant. This is an engineering blog post about large-scale code migrations with Claude Code. It describes:
   - Dynamic workflows for parallel, multi-agent execution
   - Adversarial review patterns using multiple model classes
   - Build daemons that serialize expensive rebuild operations
   - Advisory pattern combining Fable 5 and Opus 4.8
   - Six-step migration process
   - Rulebook-driven fixes (amend rules, regenerate batches)
   - Parity harnesses for behavior verification
   - The core insight is that you fix the process generating the code, not the code itself. Real-world examples include Bun's million-line Zig-to-Rust migration completed in two weeks and a Python-to-TypeScript conversion of 165k lines done over a weekend. This is highly relevant to engineering workflows with Claude Code and applicable to large-scale refactors like James's work on nanoclaw and congressional-trading.

2. **working-with-claude-fable-5-in-claude-cowork** — Moderate relevance. It's a tutorial about using Fable 5 in Claude Cowork.
   - Fable 5 handles long, complex work autonomously with context retention across multi-day tasks
   - Iterative self-correction with planning and effort settings for depth control
   - Transparent planning via side panel

   This is more of a product tutorial for Cowork users, and since James primarily uses Claude Code, the insights here overlap with what's already covered in the Fable 5 and Long-Running Agent Primitives pages. I should create pages for the code migration content and either skip or briefly note the Cowork tutorial.

The code migration post is really high-signal. The key concepts are rulebook-driven migration (fixing the rules to regenerate batches rather than individual files), dynamic multi-agent workflows for parallel migration, the advisory pattern using Fable 5 and Opus 4.8 for cost-effective delegation, parity harnesses for behavior verification, and the reusable mental model of "fix the process, not the code." This definitely warrants both a source page and a concept page. For the Cowork post, I'll create a brief source page but focus on whether there's anything genuinely new beyond what we've already documented—the effort settings might be worth noting, but overall it's a tutorial for knowledge workers rather than engineers.

Now I'm checking what wiki pages already exist to avoid duplication. I can see we have pages for Claude Code, Managed Agents, and Claude Fable 5 and Mythos 5, but there's no existing concept page for the migration loop pattern. I'll create a source page for the code migration blog post, a brief source page for the Cowork post, and potentially a concept page for the migration pattern. Before I start writing, I should verify the structure by checking the Home page and sources directory to make sure I'm following the right format.

Good. I can see existing source pages. I need to create:
1. `Claude Blog - AI Code Migration.md` — high signal, new
2. `Claude Blog - Fable 5 in Claude Cowork.md` — moderate signal

Also check if there's a `Claude Blog - Best Practices for Claude Cowork.md` already (yes there is) and `Claude Blog - Claude Cowork Product Guide.md` (yes). The Cowork Fable 5 post may add to these.

Let me also check the concepts directory for existing related concepts.
The code migration post is particularly valuable. I should start writing these pages now, and I'm thinking the "Fix the Process Not the Code" pattern—this rulebook-driven migration loop—deserves its own concept page. Let me look through the concepts directory to see what's already there.

Good. I have the concepts directory. I can see `Builder-Verifier Loop Pattern.md` and `Claude Code Dynamic Workflows.md` already exist. The code migration post connects to both of these.

The key new concept from the code migration post that warrants its own page:
- **Rulebook-Driven Migration Loop** — fix the translation rulebook, regenerate the batches; parity harnesses for verification when test suites aren't portable; the core insight "fix the process not the code"

This is distinct from the Builder-Verifier Loop which is more about build/test cycles.

Now I'm planning the files to create: the source page for the AI Code Migration post, a dedicated concept page for the Rulebook-Driven Migration Loop pattern, and a source page for the Fable 5 post about Claude Cowork. Since we already have Best Practices and Product Guide pages, the Cowork post will be brief. Then I'll update the Home and Ingest Log to reflect these additions.


High-signal content from both. Writing pages now — the code migration post is especially valuable (real technique, not just testimonial).

# Claude Blog - AI Code Migration

**URL:** https://claude.com/blog/ai-code-migration
**Date:** July 16, 2026
**By:** Anthropic (features work by Jarred Sumner / Bun, and Mike Krieger)
**Type:** Engineering workflow guide

## Core claim

Code migrations—historically multi-year projects—can now be completed in days or weeks using Claude Code's multi-agent loop architecture. The key insight:

> "You don't fix the code. **You fix the process (loop) that produced the code.**"

## Real-world examples

| Migration | Size | Duration |
|---|---|---|
| Bun: Zig → Rust | 1 million lines | 2 weeks (100% test suite passing pre-merge) |
| Python → TypeScript | 165,000 lines | One weekend |

## Six-step migration process

1. **Create rulebook + dependency map** — document translation rules and file dependencies
2. **Stress-test the rules** — run a small batch, find where the rulebook breaks
3. **Translate everything** — run the full batch with validated rules
4. **Compile** — build daemon serializes rebuild operations, feeds errors back to fixer agents
5. **Run smoke tests** — parity harness validates behavior
6. **Verify behavior matching** — seven real-world scenarios (Mike Krieger's method)

## Key techniques

### Rulebook-driven fixes
When a pattern fails, you amend the translation rulebook — not individual files. The amendment then regenerates the entire affected batch. One fix, propagated everywhere.

### Mechanical work queues (resumable)
Check for output file existence on disk to determine what still needs processing. Migrations resume from where they left off with no bookkeeping.

### Build daemons
Serialize expensive rebuild operations and pipe compiler errors back to fixer agents as structured input. Prevents agents from rebuilding the same file repeatedly.

### Advisory pattern (cost-efficient)
Combine Claude Fable 5 (reasoning) + Opus 4.8 (workhorse) for cost-effective delegation. Fable 5 handles judgment calls; Opus 4.8 handles mechanical translation.

### Parity harnesses
When the legacy test suite isn't portable to the new language, build behavior-matching harnesses. Mike Krieger used seven real-world scenarios to validate behavior equivalence.

### Adversarial review
Use multiple model classes to cross-verify migration output. Avoids the primary agent convincing itself its own work is correct.

## Concept pages

- [[Rulebook-Driven Migration Loop]] — the core pattern from this post
- [[Builder-Verifier Loop Pattern]] — adjacent pattern for any build/test cycle
- [[Claude Code Dynamic Workflows]] — multi-agent parallelism underlying the migration approach

## Applicability

- **Any large-scale refactor in James's projects** — qip-qien TypeScript codebase, congressional-trading Python → any future language move, nanoclaw provider routing refactor
- **Pattern to watch:** the "fix the rulebook, regenerate the batch" principle applies to any repetitive code transformation, not just language migrations

Serialize expensive rebuild operations and pipe compiler errors back to fixer agents as structured input. Prevents agents from rebuilding the same file repeatedly.

### Advisory pattern (cost-efficient)
Combine Claude Fable 5 (reasoning) + Opus 4.8 (workhorse) for cost-effective delegation. Fable 5 handles judgment calls; Opus 4.8 handles mechanical translation.

### Parity harnesses
When the legacy test suite isn't portable to the new language, build behavior-matching harnesses. Mike Krieger used seven real-world scenarios to validate behavior equivalence.

### Adversarial review
Use multiple model classes to cross-verify migration output. Avoids the primary agent convincing itself its own work is correct.

## Concept pages

- [[Rulebook-Driven Migration Loop]] — the core pattern from this post
- [[Builder-Verifier Loop Pattern]] — adjacent pattern for any build/test cycle
- [[Claude Code Dynamic Workflows]] — multi-agent parallelism underlying the migration approach

## Applicability

- **Any large-scale refactor in James's projects** — qip-qien TypeScript codebase, congressional-trading Python → any future language move, nanoclaw provider routing refactor
- **Pattern to watch:** the "fix the rulebook, regenerate the batch" principle applies to any repetitive code transformation, not just language migrations


# Rulebook-Driven Migration Loop

**Origin:** [[Claude Blog - AI Code Migration]] (Jul 2026)
**Pattern type:** Large-scale code transformation loop

## The core insight

> "You don't fix the code. You fix the process (loop) that produced the code."

When migrating a large codebase, individual file fixes don't scale. A single translation error can affect thousands of files. The correct lever is the **rulebook** — the set of transformation rules the agents apply. Fix the rule once; the regeneration loop propagates the fix everywhere.

## How it works

```
┌─────────────────────────────────────────────────────┐
│  Rulebook  ──→  Batch Generator  ──→  Output Files  │
│      ↑                                    │         │
│      │          Compiler / Tests          │         │
│   Fix rule  ←──  Error Feedback  ←────────┘         │
└─────────────────────────────────────────────────────┘
```

1. **Rulebook** encodes translation patterns (e.g., "Python dict comprehension → TS Record<K,V>")
2. **Batch generator** applies rules across all files; work queue tracks what's done via file existence checks (resumable)
3. **Build daemon** serializes compiles, feeds structured errors back as input to fixer agents
4. **Fixer agents** identify which rule broke → amend rulebook → regenerate affected batch
5. **Parity harness** verifies behavior equivalence, not just compilation success

## When to use

- Large-scale language migration (thousands of files)
- Any repetitive code transformation across a big codebase (API version upgrade, naming convention change, framework swap)
- Situations where fixing individual files is slower than fixing the pattern that generated them

## When NOT to use

- Small codebases where manual review per file is faster
- Migrations with high semantic variability (each file needs unique judgment)

## Key implementation primitives

| Primitive | Purpose |
|---|---|
| **Work queue via file existence** | Resumable — restart without re-processing completed files |
| **Build daemon** | Serializes rebuilds; no duplicate compiles |
| **Advisory model split** | Fable 5 for judgment (rulebook fixes), cheaper model for execution (batch generation) |
| **Parity harness** | Behavior validation when test suite isn't portable |

## Relationship to other patterns

- Extends [[Builder-Verifier Loop Pattern]] — adds the "fix the rulebook" level above fix-individual-file
- Relies on [[Claude Code Dynamic Workflows]] — parallel agents process independent work units
- The build-daemon feedback loop echoes the Default-FAIL contract in [[Long-Running Agent Primitives]]

## Real-world proof

- Bun: 1M-line Zig→Rust migration in 2 weeks (100% test suite)
- Python→TypeScript: 165k lines over a weekend

# Claude Blog - Fable 5 in Claude Cowork

**URL:** https://claude.com/blog/working-with-claude-fable-5-in-claude-cowork
**Date:** July 16, 2026
**By:** Josefina Albert (Anthropic Education team)
**Type:** Tutorial / best-practices guide

## What's new vs earlier Cowork posts

Focused specifically on Fable 5's extended autonomy and self-correction in Cowork workflows. Key additions over [[Claude Blog - Best Practices for Claude Cowork]]:

- **Effort settings** — adjustable effort levels control planning depth and verification frequency (new control surface not in earlier docs)
- **Transparent planning panel** — side panel shows Claude's step-by-step workflow before it executes; catch errors before they compound
- **Multi-day context retention** — Fable 5 maintains coherence across tasks that span days, not just a session

## Core framing

> "Working with it resembles working with a highly capable colleague: you explain the situation, agree on what a strong final result looks like, and let your colleague work."

Delegation model: give Fable 5 the goal and definition of done; it handles planning, approach, and timing. User role shifts to reviewing and approving outputs.

## Use cases highlighted

- Deep research synthesis
- Due diligence reviews
- Batch contract analysis

## Relevant to James

- Low direct relevance — Cowork-focused (James uses Claude Code primarily)
- **Effort settings concept** is worth watching: if effort tuning lands in Claude Code, it's a cost-optimization lever (lighter effort for routine tasks, heavier for reasoning-critical ones)
- The "define done before delegating" principle reinforces [[Long-Running Agent Primitives]] Default-FAIL contract
