8
9	- **[[Claude Blog - AI-Native SDLC Security]]** (new source page) — Jason Clinton (Anthropic Deputy CISO) explains how Anthropic secures an SDLC where Claude authors about 80% of merged code and more than half of code is merged by internal [[Claude Tag Plugins]]. Key mechanics: context-connected Claude project security reviews, secure coding guidance encoded into CLAUDE.md files and org-wide skills, bug-class feedback loops, remote VM + egress allowlisting for agent containment, narrow multi-agent PR reviewers that must prove findings, risk-tiered human gates, continuous AI-powered DAST, single-purpose incident agents, and SIEM logging for every automated approval/tool call/agent message. New concept: [[AI-Native SDLC Security Loop]]. Updated [[Claude Code]] and [[Claude Tag Plugins]] notes.

11	## 2026-07-21 (X article — @0xRafy)
12
13	- **[[X - 0xRafy - Graph Engineering with Claude]]** (new source page) — @0xRafy, published as X Article. Dense 11-step playbook for moving from single-loop agents to multi-agent graphs. Four eras (prompt → context → loop → graph), four building blocks (Node/Edge/Router/State), five patterns (sequential chain, router, parallel fan-out, loop-with-gate, human-in-the-loop). Key practitioner insights: routing is classification → Haiku, not Sonnet; merge node needs its own prompt and quality bar; builder and reviewer must be different agents; state discipline is how you debug a broken graph. Full working example: ticket classifier → router → drafter → reviewer → ship or retry. No framework dependency. ~42K views, 88 bookmarks. New concept page: [[Graph Engineering Patterns]]. Ingested immediately (full content already in context via Twitter MCP fetch).

15	## 2026-07-21 (Claude blog check)
16
17	- **[[Claude Blog - Datadog Universal Machine Tool for Claude Code]]** (new source page) — Datadog VP Eng Sesh Nalla + Claude Code. Core innovation: **Temper**, a deterministic spec kernel. Instead of generating code, agents produce specifications; the kernel verifies them through a 4-layer cascade (symbolic reasoning → exhaustive state exploration → deterministic simulation → property testing) and deploys the running system the spec describes. Spec = proof artifact = executing artifact — no drift. Three predecessor projects (Courier, BitsEvolve, Helix) converged on the verification bottleneck as the core problem. "Dark factory" framing: agents work autonomously inside Temper's formal kernel. "A lot of software is just control logic around database APIs — Temper could be universal." High-assurance software rigor (aviation, finance) now feasible for general software via agents. GitHub: `nerdsane/temper`. New concept: [[Specification-First Agentic Development]].
18
19	## 2026-07-21 (Anthropic GitHub sweep #36)
20
21	- All 30 updated repos already documented or skipped per prior sweeps. Three new repos not yet documented but not relevant to James's stack: `anthropic-sdk-php` (PHP API SDK), `anthropic-sdk-csharp` (C# API SDK), `PySvelte` (Python/JS visualization library — unmaintained research tool). No new skill commits.
22
23	## 2026-07-20 (migrated cross-project learnings out of stagehand's auto-memory, via /goal)
24
25	- **[[Symlink Hijack in Skill Updaters]]** (new concept page) — James asked whether Claude would find value in a longer-term memory store beyond the per-project auto-memory directory. Answer, tested by actually doing it: yes, mainly because auto-memory is siloed per project path and invisible to Codex, so anything that generalizes beyond one repo is misfiled the moment it's saved there. This page migrates the generalizable half of stagehand's `hyperframes-skill-freshness-tooling` memory — the trap where `hyperframes skills update` auto-discovers and relinks every agent's skill dir under `$HOME`, and the detect-don't-adopt fix. The stagehand-specific tooling facts (exact scripts, launchd schedule) moved to the `projects-monorepo-infra` portfolio card instead, since that tooling lives in the root `projects/` repo, not stagehand.
26	- **[[Converge on One Canonical Engine]]** (new concept page) — Migrated the generalizable half of stagehand's `agent-instruction-symmetry` memory: two agents each defaulting to their own implementation for the same capability (HyperFrames vs. ffmpeg photo-slideshow for the same "listing reel" output) diverge silently because each only sees its own output succeed. Root cause was an asymmetric instruction file (`AGENTS.md` with no mirrored `CLAUDE.md`), not a knowledge gap. The stagehand-specific bug narrative and fix commit stay in stagehand's own auto-memory and `CLAUDE.md`, since they're not portable.
27	- Established the store-routing rule going forward (see `[[Memory Store Routing]]`-equivalent auto-memory feedback entry, kept in stagehand's project memory since it's process guidance about *how this agent uses memory*, not wiki knowledge): content lives in exactly one store — auto-memory shrinks to pointers, repo docs keep repo-only truths, second brain holds judgment-heavy and cross-project patterns.
28
29	## 2026-07-16 (fixed the wiki app's own click bug, via /goal)
30
31	- **[[A Reported Click Does Nothing Bug Can Be An Off-Screen Render]]** (new concept page) — James reported search results in this very wiki app weren't clickable. Code review and a desktop-viewport Playwright test both looked clean; the bug only reproduced at a phone-width viewport, where the reader panel reflows below the sidebar with no auto-scroll — the click worked, the result just rendered off-screen. Fixed with a viewport-gated `scrollIntoView` after selection. Also fixed in the same pass: `.missing-link` had no CSS (broken wikilinks were invisible as broken), graph edge lines had no `pointer-events:none` (an edge could swallow a node's click), and the graph's fixed-radius jitter layout guaranteed node overlap past ~5 pages per section (replaced with a golden-angle spiral, radius-capped per section). Added a Playwright suite (`second-brain/tests/`, desktop Chromium + mobile Safari) plus `package.json`/`CLAUDE.md`/`AGENTS.md` — second-brain was missing standard monorepo scaffolding relative to other projects.
32
33	## 2026-07-16 (second-brain systemic-use review, via /goal)
34
35	- **[[Named-But-Unbuilt Skill References in CLAUDE.md]]** (new concept page) — Root CLAUDE.md named `get-from-secondbrain`/`add-to-secondbrain` as if they were existing primitives; neither existed anywhere (no skill, no script). Built both for real as `.claude/skills/get-from-secondbrain/` and `.claude/skills/add-to-secondbrain/`, and repointed CLAUDE.md's Cross-Project and Learning Law sections at them. Also added a routing rule against project-local `docs/solutions/` (compound-engineering's `ce-compound`) to avoid the two knowledge stores fragmenting silently.
36	- **New portfolio card:** `projects-monorepo-infra` — the root `~/projects` folder itself (launcher/serve.py, Tailscale funnel, local-model coding ladder, cross-agent state) was undocumented despite 11+ recent commits. Added card + BOARD.md row.
37	- **Retrofit from project-local `docs/solutions/`:** scanned the 3 existing per-repo docs/solutions folders (RoadSense, CodexBar, CodexBarLocal — only place that convention is in use) for entries that generalize beyond one repo. Two did: **[[Layer-Matrix Verification for Multi-Layer Rendering Bugs]]** (from RoadSense's Mapbox ridden-indicator bug — cross-links into the existing widget-verification notes) and **[[Default-Off for Heavy Optional Background Features]]** (from CodexBar's OpenAI web-extras battery-drain fix). Original `docs/solutions/` files left in place (repo-local detail plus the cross-project extraction now also live in second-brain); this is a one-time retrofit, not an ongoing sync — new captures should route directly per the rule in `add-to-secondbrain`.
38
39	## 2026-07-15 (local coding delegation — model-discovery sources)
40
41	- **[[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.
42
43	## 2026-07-17 (Claude blog check)
44
45	- **[[Claude Blog - Working at the Frontier Cursor]]** (new source page) — Cursor's production evaluation of Fable 5; 72.9% on CursorBench. Key concept: *global vs local reasoning* — global reasoning comprehends the whole problem space before acting (handles "I don't know where B is" tasks); local reasoning is reactive to immediate steps (fine when B is clear). Model routing insight: route by problem *ambiguity*, not just complexity — Fable for underspecified problems, cheaper models for clear-spec tasks. CursorBench deliberately uses messy, underspecified prompts; Moon Landing Test for open-ended long-horizon comparison. Extends [[Frontier Code Evaluation]] and [[Claude Fable 5 and Mythos 5]]. Applicable to nanoclaw provider routing (route ambiguous requests to Fable, mechanical ones to Opus/Sonnet).
46	- **[[Claude Blog - CISO Guide to Agentic AI]]** (new source page) — Jason Clinton (Anthropic Deputy CISO). Four-question agent assessment (untrusted content ingested? actions + identity? blast radius? observability?) + seven governance requirements (IdP identity, connector allowlists, per-tool approvals, sandboxed execution, egress allowlisting, SIEM telemetry, org-wide kill switch). Service account agents (single-purpose, system identity — preferred) vs human credential agents. Notable: Anthropic's own IR agent spontaneously contacted another agent to draft code fixes — emergent agent-to-agent comms. "Design for where the model will be in 6 months." Applicable to qip-qien auth design (the 4 questions map exactly to the SEV-1 auth issue).
47
48	## 2026-07-19 (The Prompting Playbook — CwC London 2026)
49
50	- **[[Claude CwC - The Prompting Playbook]]** (new source page) — Margot van Laar (Anthropic), Code with Claude London, May 19, 2026. Five strategies: (1) XML-tag structure separating role/policy/guidelines/context/task/output_format, (2) delete legacy instructions — audit every unexplained defensive patch and ask what model it was written for, (3) tools > instructions (math/JSON/retrieval as capabilities, not adjectives), (4) present both sides of tradeoffs so the model can reason about them, (5) split complex tasks into Generator→Evaluator→Repairer loop for lower tokens + higher reliability. Eval-first is the throughline: minimum viable eval needs control + edge + boundary cases; prompt changes without evals are vibe checks. Key mindset shift: older prompts did reasoning for models; newer models reason independently — give inputs, not conclusions. ROI: qip-qien prompt structure, congressional-trading scoring loop split, StageHand narration generation, CLAUDE.md legacy patch audits across all projects.

Ingest Claude blog security post to wiki


The blog post "Claude Blog - AI-Native SDLC Security" was already ingested on 2026-07-21. It's fully documented with a source page, concept page, and ingest log entry. The Home.md is also updated.

So this is a case where the blog monitor detected a post that was already ingested. I should inform James that the blog was checked and the post was already fully ingested (likely during an earlier pass today).

Let me send James a brief message about this.


The post was already fully ingested earlier today. The ingest log entry (line 9) confirms it with source page, concept page, and Home.md updates all in place.


Claude blog checked — the new post was already fully ingested earlier today:

- **[[Claude Blog - AI-Native SDLC Security]]** (Jason Clinton, July 21) — already in the wiki with source page, concept page ([[AI-Native SDLC Security Loop]]), and ingest log entry. Nothing left to do.

Instructions:
Check for new or updated Anthropic GitHub repos and ingest anything relevant into the second brain wiki at /workspace/extra/second-brain/.

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>


Let me analyze the updated repos list. Most of these are repos I've already documented in the wiki. Let me check which ones might have genuinely new content worth ingesting.

Looking at the list:
- `anthropics/skills` — already documented as [[Anthropic Skills Repo]]
- `anthropics/claude-code` — already documented as [[Claude Code]]
- `anthropics/claude-code-security-review` — already documented as [[Claude Code Security Review]]
- `anthropics/claude-plugins-official` — already documented as [[Claude Plugins Official]]
- `anthropics/claude-agent-sdk-demos` — already documented as [[Claude Agent SDK Demos]]
- `anthropics/code-migration-kit-with-claude-code` — already documented as [[Claude Code Migration Kit]]
- `anthropics/claude-cookbooks` — already documented as [[Claude Cookbooks]]
- `anthropics/claude-code-action` — already documented as [[Claude Code Action]]
- `anthropics/cwc-long-running-agents` — this might be related to [[Long-Running Agent Primitives]] or [[Anthropic CWC Workshops]]
- `anthropics/financial-services` — already documented as [[Claude for Financial Services]]
- `anthropics/claude-for-legal` — already documented as [[Claude for Legal]]
- `anthropics/knowledge-work-plugins` — already documented as [[Knowledge Work Plugins]]
- `anthropics/courses` — already documented as [[Anthropic Courses]]
- `anthropics/prompt-eng-interactive-tutorial` — already documented as [[Anthropic Prompt Engineering Tutorial]]
- `anthropics/k12-teacher-skills` — NEW! "Skills and eval rubrics for K-12 teachers, co-developed with Learning Commons" — not in wiki
- `anthropics/jacobian-lens` — "Companion code for the global workspace interpretability paper" — research/interpretability, not directly relevant
- `anthropics/life-sciences` — already documented as [[Claude for Life Sciences]]
- `anthropics/claude-agent-sdk-python` — already documented as [[Claude Agent SDK Python]]
- `anthropics/cwc-workshops` — already documented as [[Anthropic CWC Workshops]]
- `anthropics/anthropic-sdk-python` — base SDK, not specifically documented but fundamental
- `anthropics/claude-constitution` — already documented as [[Claude Constitution]]
- `anthropics/anthropic-cli` — already documented as [[Anthropic CLI]]
- `anthropics/claude-plugins-community` — already documented as [[Claude Plugins Community]]
- `anthropics/buffa` — Rust protobuf implementation, infrastructure lib — skip
- `anthropics/healthcare` — already documented as [[Claude for Healthcare]]
- `anthropics/claude-quickstarts` — already documented as [[Claude Quickstarts]]
- `anthropics/launch-your-agent` — already documented as [[Launch Your Agent]]
- `anthropics/claude-ai-mcp` — issue tracker for MCP integration, not a tool/skill repo — skip
- `anthropics/claude-desktop-buddy` — already documented as [[Claude Desktop Buddy]]
- `anthropics/claude-agent-sdk-typescript` — already documented as [[Claude Agent SDK TypeScript]]

So the potentially new ones are just the K-12 teacher skills repo.

`anthropics/k12-teacher-skills` is new content about skills and evaluation rubrics for K-12 teachers developed with Learning Commons — it's education-focused and not directly relevant to James's stack, so I'll skip it. `anthropics/cwc-long-running-agents` might overlap with the long-running agent primitives workshop we've already documented, and `anthropics/jacobian-lens` is interpretability research so I'll skip that too. Most of these repos are already covered, so there's not much new to ingest from this sweep. The eval rubrics could offer some insights into skills architecture, but given that James is focused on AI agent workflows rather than education, this is probably lower priority. Most of these updates look like routine maintenance across the board—likely from a coordinated release or CI process rather than substantial new content. Let me pull a few READMEs from the potentially novel repos to see what's actually there.


Looking through the repo list — most are already documented. Two stand out as potentially new: `k12-teacher-skills` (not in wiki) and `cwc-long-running-agents` (possibly separate from the CwC workshops already documented). Let me check those.

# Agent Skills for K-12 Teachers
Source code and evaluation framework for the agent skills that are included with [Claude for Teachers](https://claude.com/solutions/teachers).

Included are two skills:
- `k12-lesson-planning`: Builds classroom-ready, standards-aligned lesson plans, optionally aligned to a teacher's curriculum
- `k12-lesson-differentiation`: Adapts an existing lesson into tiered versions (below / at / above proficiency-level) and for specific student needs, keeping core content consistent across tiers

Where noted, materials in this repo were co-developed between Anthropic and Learning Commons, who collaborated to help Claude create classroom materials that are grounded in academic standards and follow best practices from learning science research.

The skills are written to make effective use of the Learning Commons Knowledge Graph [Claude connector](https://claude.com/connectors/learning-commons-knowledge-graph) that is included for all teachers using Claude for Teachers. This connector provides Claude with access to academic standards across all 50 states and progressions beneath them; adapt the skills if your environment does not have access to these tools.

## Quick start
There are two options to use these skills:

**In Claude for Teachers:**
If you have a Claude for Teachers account, there is no extra install needed. These skills are already installed for you.

**In other places:**
Load the plugin or skills manually. For instance, in Claude Code:

```
git clone https://github.com/anthropics/k12-teacher-skills
claude plugin marketplace add ./k12-teacher-skills/plugin
claude plugin install k12-teacher-skills@k12-teacher-skills
```

## Layout

- `plugin/` - Main skill content bundled as a plugin; also includes teacher-focused 3rd party MCP servers that are available for users to enable
- `evals/` - Contains our evaluation framework and how to adapt them for your use case

# Harness Primitives for Long-Running Claude Agents

Claude Code's built-in [`/goal`](https://code.claude.com/docs/en/goal) command gives you a generator/evaluator loop out of the box: set a completion condition and a separate fast model checks it after every turn until it's met. This repo ships the same underlying primitives as short, readable [hooks](https://code.claude.com/docs/en/hooks) and a [subagent](https://code.claude.com/docs/en/sub-agents), so you can see how each mechanism works and assemble a harness tuned to your project. The patterns come from [Effective Harnesses for Long-Running Agents](https://www.anthropic.com/engineering/effective-harnesses-for-long-running-agents) (Nov 2025) and [Harness Design for Long-Running Application Development](https://www.anthropic.com/engineering/harness-design-long-running-apps) (Mar 2026). We recommend trying both the in-product features and a custom harness to see which fits your workflow.

| | In-product | Custom harness (this repo) |
|---|---|---|
| **What runs the loop** | [`/goal`](https://code.claude.com/docs/en/goal) | the [primitives below](#the-quality-loop) + a [loop you write](#running-the-loop) |
| **Who judges "done"** | a separate fast model checking your condition | your [`agents/evaluator.md`](./claude-code-config/.claude/agents/evaluator.md) with your prompt |
| **Where it works** | Claude Code interactive, [`-p`](https://code.claude.com/docs/en/headless), Remote Control | Claude Code, headless, or [Agent SDK](https://docs.claude.com/en/docs/claude-code/sdk) |

Three primitives form the quality loop:

- **Default-FAIL contract.** Every criterion starts `false`; the agent can't mark it passing without opening evidence first.
- **Fresh-context evaluator.** A separate agent with no Write/Edit tools grades the work from a context window that never saw the build.
- **Agent-maintained handoff.** The agent writes its own progress notes and commits to git so the next session picks up cleanly.

Two more operator-control hooks are included for when you want to watch or intervene. The same patterns translate directly to `PreToolUse`/`Stop` callbacks in the [Agent SDK](https://docs.claude.com/en/docs/claude-code/sdk).

> Built as the take-home for the Long-Running Agents station at Code with Claude 2026. **These are example ingredients, not a turnkey harness.** Event demo; not maintained and not accepting contributions.

## How to use this repo

**Read and cherry-pick.** Each primitive is one standalone file with no dependency on the others. The [quality-loop table](#the-quality-loop) below maps every one to its example here and its Agent SDK equivalent. Open the file, see how the mechanism works, copy what fits.

**Or copy all of them as a starting point.** In your project, run `claude` and paste:

> Clone github.com/anthropics/cwc-long-running-agents into /tmp, copy its `claude-code-config/.claude/` directory into this project's root, make the hook scripts executable, then walk me through what each hook and the evaluator subagent does and what I'll need to adapt for this project.

or do it yourself:

```bash
cp -r claude-code-config/.claude /path/to/your/project/
chmod +x /path/to/your/project/.claude/hooks/*.sh
```

Either way, this gives you all the examples wired into `.claude/` at once. Before relying on them: point `RESULTS_FILE` at your project's actual results file, adjust the evidence-file pattern in `track-read.sh`, and run `claude` from the directory that contains `.claude/` (hooks are not loaded when launching from a subdirectory).

**If you're on the Agent SDK,** this repo is a pattern reference. The shell hooks here translate one-to-one to `PreToolUse`/`Stop` callbacks. To scaffold an SDK agent from inside Claude Code, install the [`agent-sdk-dev` plugin](https://github.com/anthropics/claude-plugins-official/tree/main/plugins/agent-sdk-dev) and ask Claude to build an agent that implements whichever of these primitives you want. For a hand-written starting point, see the [autonomous-coding quickstart](https://github.com/anthropics/claude-quickstarts/tree/main/autonomous-coding) or the [agent-sdk-workshop](https://github.com/anthropics/agent-sdk-workshop) curriculum.

## The quality loop

| Primitive | Claude Code example | Agent SDK equivalent | Enforcement |
|---|---|---|---|
| **Default-FAIL contract** | [`hooks/track-read.sh`](./claude-code-config/.claude/hooks/track-read.sh) + [`hooks/verify-gate.sh`](./claude-code-config/.claude/hooks/verify-gate.sh) | `PreToolUse` callback | hook |
| **Fresh-context evaluator** | [`agents/evaluator.md`](./claude-code-config/.claude/agents/evaluator.md) subagent (no Write/Edit) | [`evaluator_optimizer.ipynb`](https://github.com/anthropics/claude-cookbooks/blob/main/patterns/agents/evaluator_optimizer.ipynb) | you invoke it |
| **Agent-maintained handoff** | [`CLAUDE.md`](./claude-code-config/.claude/CLAUDE.md) + [`hooks/commit-on-stop.sh`](./claude-code-config/.claude/hooks/commit-on-stop.sh) | system prompt + `Stop` callback | convention + hook backstop |

### Default-FAIL contract

Agents will mark a feature "passing" after a unit test or a curl when the UI is visibly broken. Asking nicely in the prompt doesn't reliably stop this. The harness makes "done" structural. Every feature is a row in a `test-results.json` file you create in your project:

```json
{ "feature-1": { "passes": false }, "feature-2": { "passes": false } }
```

The only evidence that counts is a file matching the patterns in `track-read.sh` (screenshots, console logs, result files), and a `PreToolUse` hook denies any write to the results file unless the agent has first opened one with the Read tool. The agent can't claim success it hasn't observed. (The shipped hook is intentionally simple; see the comments in `verify-gate.sh` for the gaps a production version would close.)

### Fresh-context evaluator

The builder shouldn't grade its own work. After each feature, you (or your wrapper script) invoke a separate subagent (`agents/evaluator.md`) with no Write/Edit tools that reviews the diff and the screenshots from a context window that never saw the build, then returns `PASS` or `NEEDS_WORK` with specific findings. On `NEEDS_WORK` the findings become the next builder session's starting prompt, closing the build/evaluate/rebuild loop. Invoke it from your wrapper with `claude --agent evaluator -p "<review prompt>"`; what your loop does with the verdict is up to you.

### Agent-maintained handoff

A fresh session has no memory of what the previous one did, and when a long session fills its context window Claude Code summarizes the history, which loses detail. So the agent maintains the handoff itself: it scopes each session to one feature, writes to a structured `PROGRESS.md` as it works and re-reads it first thing on every restart, and `git add`s and commits at meaningful checkpoints so `git log` is a second record. `commit-on-stop.sh` is the backstop that catches whatever's still uncommitted at session end. This is the layer most sensitive to model capability; newer models drift less and self-scope better, so re-evaluate how much of `CLAUDE.md` you still need after each model release (see [Re-simplify on model upgrades](#going-further)).

A fourth core piece, a **rubric for subjective work**, isn't shipped here because it's project-specific; see [Going further](#going-further) for how to add one to the evaluator.

## Running the loop

Two ways to keep the build → evaluate → rebuild cycle going. `/goal` is built into Claude Code and works with or without this repo's primitives; the second path wires the contract file and your own `evaluator.md` directly into the loop.

### `/goal`: built-in completion checker

```
/goal every feature in PROGRESS.md is implemented, committed, and its tests pass
```

After every turn a separate fast model checks the condition and keeps the session going until it's met. One line, no contract file or hooks. Works the same in interactive Claude Code, [`claude -p`](https://code.claude.com/docs/en/headless), and Remote Control. See the docs for [writing an effective condition](https://code.claude.com/docs/en/goal#write-an-effective-condition) and how `/goal` [compares to `/loop` and Stop hooks](https://code.claude.com/docs/en/goal#compare-to-other-autonomous-workflows).

### Your `evaluator.md` as the gate

When you want the default-FAIL contract (`test-results.json` + `verify-gate`) enforcing evidence and your own evaluator prompt deciding `PASS`/`NEEDS_WORK`, the loop lives in your code. How depends on where you're running:

| Surface | How |
|---|---|
| **Claude Code** | custom [Stop hook](https://code.claude.com/docs/en/hooks#stop) runs the evaluator as a fresh `claude` process after each turn and blocks on anything but `PASS` |
| **Headless** ([`claude -p`](https://code.claude.com/docs/en/headless)) | wrapper script calls `claude --agent evaluator -p` between builds (example below) |
| [**Agent SDK**](https://docs.claude.com/en/docs/claude-code/sdk) | separate generator and evaluator `query()` calls; see [`evaluator_optimizer`](https://github.com/anthropics/claude-cookbooks/blob/main/patterns/agents/evaluator_optimizer.ipynb) |

```bash
while grep -q '"passes": false' test-results.json; do
  claude -p "Read PROGRESS.md and build the next unfinished feature per CLAUDE.md."
  VERDICT=$(claude --agent evaluator -p "Review the most recent commit against its spec.")
  [ "$(echo "$VERDICT" | head -1)" = "PASS" ] || echo "$VERDICT" > NEXT_FINDINGS.md
done
```

Each pass is a fresh context. Exit when the contract file has nothing left failing, a cycle makes no changes, or a budget is hit; `touch AGENT_STOP` to stop early. The builder writes `test-results.json` (verify-gate enforces evidence-read first) and the evaluator returns a separate verdict; have your wrapper write the contract on `PASS` instead if you want "all true" to mean "independently confirmed."

## Operator controls


Great, I now have the content for both repos:

1. **`anthropics/k12-teacher-skills`** — Skills for K-12 teachers: `k12-lesson-planning` and `k12-lesson-differentiation`. Part of "Claude for Teachers" product. Co-developed with Learning Commons. Uses Learning Commons Knowledge Graph connector. Relevant because it's an officially documented use case of the skills system, and has an eval framework. However, not directly in James's use case/stack - he's not in education. Low relevance.

2. **`anthropics/cwc-long-running-agents`** — This is VERY relevant.

It's the reference implementation for the CwC Long-Running Agents station, containing concrete patterns like a default-fail contract that prevents agents from marking work complete without evidence, a fresh-context evaluator that grades work independently, structured handoff mechanisms with progress tracking and git commits, and the `/goal` command for built-in completion checking. This is the practical code backing the more abstract Long-Running Agent Primitives concept page, so I should check what that existing documentation covers.

Looking at the Home.md reference, the concept page outlines three core primitives (Default-FAIL, Fresh-context evaluator, Handoff) plus two operator hooks (kill switch, STEER.md) from Anthropic's own patterns. The repo is essentially the working implementation of what's already documented conceptually. I don't see a dedicated source page for this specific CwC workshop in the wiki, though there's a broader Anthropic CWC Workshops page that covers multiple workshops but not this one specifically.

The repo adds concrete implementation details beyond the concept page — hook scripts for tracking and verification, the `/goal` command as a built-in alternative, headless invocation patterns using the Agent SDK, a bash loop template for the build-evaluate-rebuild cycle, and connections to PreToolUse and Stop callbacks. Worth updating the existing Long-Running Agent Primitives page with these implementation details and possibly creating a source page for the workshop materials.

I'm noticing that all 30 repos were updated around the same time, which suggests this is likely a batch CI run or metadata change rather than genuine new content across the board. Most of these repos don't have meaningful updates to ingest. I'm skipping infrastructure tooling like the Rust protobuf implementation and research-focused code like the interpretability paper companion code since they're not directly applicable to the projects at hand.

For `k12-teacher-skills`, while the eval rubrics framework could be interesting, it's education-focused rather than agentic tooling, so I'll set that aside too. Now I need to check what's already on the Long-Running Agent Primitives page to see what implementation details we'd be adding from the CwC workshop reference.


Good content in both. Let me check the existing concept page before writing anything.


find /workspace/extra/second-brain/wiki -name "Long-Running Agent Primitives*" -o -name "*Long-Running*" 2>/dev/null

curl -s "https://raw.githubusercontent.com/anthropics/cwc-long-running-agents/main/README.md" 2>/dev/null | grep -A 30 "Operator controls" | head -50


## Operator controls

Two more hooks for when you want to watch the loop run or intervene mid-stream:

| Hook | What it does |
|---|---|
| [`hooks/kill-switch.sh`](./claude-code-config/.claude/hooks/kill-switch.sh) | Halts every tool call while an `AGENT_STOP` file exists at the project root. |
| [`hooks/steer.sh`](./claude-code-config/.claude/hooks/steer.sh) | Surfaces the contents of `STEER.md` (project root) to the agent once and clears it, so you can redirect mid-run without restarting. |

## Watching it work

Everything the agent does lands on disk, so you can observe a long run from a terminal without any dashboard code:

```bash
watch -n 2 'tail -20 PROGRESS.md'                          # its own notes
watch -n 5 'git log --oneline -8'                          # work saved
watch -n 5 'find screenshots -name "*.png" | tail -5'      # what it sees
watch -n 2 'wc -l < .claude/.evidence-reads 2>/dev/null'   # evidence reads (resets to 0 after each gated write)
```

Run them in a `tmux` grid and you have a live view of every primitive.

2
3	**Type:** Engineering patterns / reusable building blocks
4	**By:** Anthropic
5	**Repo:** https://github.com/anthropics/cwc-long-running-agents
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
60	```
61
62	## Going further (advanced patterns)
63
64	| Pattern | What it adds |
65	|---------|-------------|
66	| **Unattended loop** | Outer script caps session length, starts next one automatically. `ralph-loop` plugin in `claude-plugins-official`. |
67	| **Planner agent** | First session expands a one-line ask into a `BUILD_PLAN.md` the loop runs against |
68	| **Grading rubrics** | Evaluator uses scoring principles (functionality, design, craft) with few-shot examples instead of binary pass/fail. `frontend-design` plugin. |
69	| **Browser-verified evaluator** | Evaluator opens the running app itself via Playwright MCP instead of trusting screenshots |
70	| **Re-simplify on upgrades** | After each model release, comment out harness pieces one at a time to see what's still load-bearing |
71	| **Hosted runtime** | Claude Managed Agents hosts the loop, sandbox, and scheduling |

# Long-Running Agent Primitives

**Type:** Engineering patterns / reusable building blocks
**By:** Anthropic
**Repo:** https://github.com/anthropics/cwc-long-running-agents
**Use:** Copy `.claude/` directory or cherry-pick individual files

## 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.

## The 2 operator-control hooks

### Kill switch
Drop an `AGENT_STOP` file to halt the agent at the next checkpoint. Clean, no-force-kill needed.

### Steering (`STEER.md`)
Drop a `STEER.md` file mid-run to redirect the agent without stopping it. The agent reads it and adjusts course.

## Usage

### Built-in `/goal` (no primitives needed)
```bash
/goal every feature in PROGRESS.md is implemented, committed, and its tests pass
```
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.

### Custom harness (use the primitives)
```bash
# Copy the whole .claude/ structure into your project
cp -r .claude/ /your/project/
chmod +x /your/project/.claude/hooks/*.sh

# Headless loop example
while grep -q '"passes": false' test-results.json; do
  claude -p "Read PROGRESS.md and build the next unfinished feature."
  VERDICT=$(claude --agent evaluator -p "Review the most recent commit against its spec.")
done
```

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

## Monitoring a live run (no dashboard needed)

```bash
watch -n 2 'tail -20 PROGRESS.md'            # agent's own notes
watch -n 5 'git log --oneline -8'             # work saved
watch -n 5 'find screenshots -name "*.png" | tail -5'  # what it sees
watch -n 2 'wc -l < .claude/.evidence-reads 2>/dev/null'  # evidence reads
```

The existing page for `Long-Running Agent Primitives` is already comprehensive and up-to-date! It covers all the key elements I found in the README. The wiki is already well-documented.

Now let me think about whether there's anything actually new in the repos that would warrant an update:

1. **`cwc-long-running-agents`** — The concept page already covers all the key elements from this repo very well. The page already includes:
   - The 3 core primitives (Default-FAIL, Fresh-context evaluator, Agent-maintained handoff)
   - The 2 operator-control hooks (kill switch, STEER.md)
   - `/goal` built-in usage
   - Custom harness bash example
   - Monitoring commands
   - Going further patterns (unattended loop, planner agent, etc.)

   The page is already very complete. No meaningful updates needed.

2. **`k12-teacher-skills`** — Not relevant to James's stack (K-12 education focus).

For the other 28 repos that were all updated in a batch — this is almost certainly a coordinated release-day batch update, possibly from GitHub Actions CI runs or a cascading update from a core dependency like the Anthropic SDK.

Since `newSkillCommits` is empty and the claude-code repo updates appear to be version bumps, there's nothing new worth ingesting. All repos are already documented, the `cwc-long-running-agents` page is comprehensive, and the batch timestamp pattern suggests a coordinated release rather than new content. Let me check the Ingest Log to see what was last logged for the GitHub sweep. For Teachers product is interesting context but outside James's scope, so I'll skip it. The batch update across all 30 repos between 04:34 and 07:59 UTC suggests either a CLI/SDK release or repo-wide settings change, but since the wiki already covers what these repos offer, there's nothing new to ingest. I'll write up the log entry noting what was checked and why nothing was added. Both `buffa` and `jacobian-lens` are infrastructure and research tools respectively, neither relevant to James's needs. So I'm sticking with my conclusion: no new content to ingest, just log the sweep and notify James.


The existing `Long-Running Agent Primitives` page is already comprehensive — nothing to add there. The batch update (30 repos in ~3.5 hours) is a coordinated release pattern, not new content. Only genuinely new repo is `k12-teacher-skills` (K-12 education, out of scope for James).

Let me add a log entry and message James.

- **[[Claude Blog - AI-Native SDLC Security]]** (new source page) — Jason Clinton (Anthropic Deputy CISO) explains how Anthropic secures an SDLC where Claude authors about 80% of merged code and more than half of code is merged by internal [[Claude Tag Plugins]]. Key mechanics: context-connected Claude project security reviews, secure coding guidance encoded into CLAUDE.md files and org-wide skills, bug-class feedback loops, remote VM + egress allowlisting for agent containment, narrow multi-agent PR reviewers that must prove findings, risk-tiered human gates, continuous AI-powered DAST, single-purpose incident agents, and SIEM logging for every automated approval/tool call/agent message. New concept: [[AI-Native SDLC Security Loop]]. Updated [[Claude Code]] and [[Claude Tag Plugins]] notes.
