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 | $0.00643 | $0.00643 |
| Opus 5.5 | $0.00257 | $0.00257 |
| Sonnet 5.5 | $0.00129 | $0.00129 |
| Haiku 4.5 | $0.00064 | $0.00064 |
Grade A, and why
contexture AGENTS.md scanned grade A with 0 findings 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 1mo 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 40 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Generated by
skills/project-instructions/project-instructions.mjsfrom the discipline corpus. Do not hand-edit — editarchitectural-rules/and re-run. Vendor-neutral; read by Codex, Cursor, Copilot, and local models. (Claude Code usesCLAUDE.md+ the corpus directly.)
Stance (how to engage)
Be objective, direct, honest — not supportive-by-default, not reflexively contrarian. Weigh trade-offs and give a reasoned position; never just accept or reject. Surface weak reasoning, hidden assumptions, and the real cost of a choice even when unasked. A helper is most useful when honest, not agreeable.
Commands
- Codemap (read before exploring):
node skills/update-codemap/codemap.mjswrites.claude/codemap.md - Codemap diagrams:
node skills/visualise-codemap/visualise-codemap.mjs - Verify install / drift:
node bootstrap/bootstrap.js --verify - (Project-specific test/lint/build commands: see the repo README or ask — fill these in per repo.)
Testing
- Run the repo's test suite before committing. Each change should be verifiable; a change with no way to tell if it worked is incomplete.
Project structure
- Read
.claude/codemap.mdfor the file-by-file map (purpose + exports). Readarchitectural-rules/for the conventions. Read.claude/architecture.mdif present. - Reusable skills are auto-discovered as Agent Skills from
.claude/skills/(runnode bootstrap/bootstrap.jsonce after cloning to generate it; committed source is repo-rootskills/).
Code style
- Architectural rules live in
architectural-rules/<scope>/:universal/always applies;<language>/applies when editing that language;config-authoring/when editing skills/agents/rules/hooks. Read the ones matching what you touch. - Match existing style. Surgical edits — do not "improve" adjacent code.
Git workflow
- One concern per commit; clear messages. Branch for feature work (
feature/<slug>), merge--no-ff. - Never add AI attribution to commits or PRs (no Co-Authored-By, no "Generated with", no robot emoji).
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.

contexture AGENTS.md is an instructions file published in the GitHub repository AcKeskin/contexture (2 stars, last pushed 2mo ago), licensed MIT. It adds 643 tokens to every session, about $0.0026 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
