What is knitbrain CLAUDE.md?

Project instructions for knitbrain, a TypeScript service that gives AI agents tools for session memory, learning, task classification, and self-checks. They describe the required session-start and verification steps.

Use them when developing knitbrain, loading or continuing a session, verifying claims, running its checks, or testing changes against the installed build.

They reduce mistakes caused by stale knowledge or unfinished work and require the agent to classify or run a task before saving new learnings or handoffs.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00892	$0.00892
Opus 5.5	$0.00357	$0.00357
Sonnet 5.5	$0.00178	$0.00178
Haiku 4.5	$0.00089	$0.00089

Security

Grade C, and why

knitbrain CLAUDE.md scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Always `rm -rf dist && npm run verify` before claiming green — stale dist masks build-order bugs. Local rebuild note: `build` re-chmods the three dist entrypoints (a globally symlinked install breaks otherwise).

How it starts

The opening of the file, as written. The whole thing — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.

knitbrain

TypeScript project (Node ≥18, ESM, vitest). This repo IS the knitbrain product — if a knitbrain MCP server is connected while developing here, note it runs the globally installed build, not your working tree; rebuild + reinstall (npm run build && npm install -g .) and reconnect to test local changes.

Session start

First action: call knitbrain_load_session — returns last handoff, top learnings, false positives. If it reports unfinished work, resume that first.

Adherence gate: close-the-loop writes (knitbrain_record_learning, knitbrain_skill_save, knitbrain_save_handoff) are blocked until knitbrain_classify_task/knitbrain_run ran this session (KNITBRAIN_STRICTNESS, default block).

Tool surface highlights (37 tools)

knitbrain_verify_claim — settle a codebase claim before LEARN. Caveat: the session MCP roots at the launch cwd — settle knit-brain facts by source + tests + built dist when the root is elsewhere.
knitbrain_self_check — keystone: audits all four invariants (anti-sycophancy, anti-stale, anti-drift, adherence) in one PASS/FAIL pass.
knitbrain_run_loop — one judge→iterate cycle per call; your verify_cmd is the hard gate.
knitbrain_search_code — retrieval layer: query → ranked function-level chunks + graph-related files, score-gated. Search BEFORE reading; knitbrain_read only the hits.
knitbrain_read / knitbrain_optimize / knitbrain_retrieve — compression loop; exact original always one retrieve away. Data-tool JSON responses are never skeletonized (machine contract).
Note: big tool responses may come back skeletonized with a trailing ⟨recall:hash⟩ — strip it before JSON-parsing a tool result.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

knitbrain CLAUDE.md is an instructions file published in the GitHub repository PDgit12/knitbrain (6 stars, last pushed 6d ago), licensed MIT. It adds 892 tokens to every session, about $0.0036 per session on Opus 5.5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
