Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00000 | $0.00854 |
| Opus 5.5 | $0.00000 | $0.00342 |
| Sonnet 5.5 | $0.00000 | $0.00171 |
| Haiku 4.5 | $0.00000 | $0.00085 |
Grade A, and why
poetry 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 5d 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 — 52 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Poetry Project Rules
Project Configuration
- For single-consumer, non-library repositories, require Python 3.12 or newer and prefer the latest stable Python release when the repository's runtime and dependencies are compatible. For public libraries, prefer the widest feasible supported range with a minimum no earlier than Python 3.11.
- Use Poetry 2.x with PEP 621
[project]metadata; do not use legacy[tool.poetry]metadata or dependency tables. - Declare runtime dependencies in
[project.dependencies], development dependencies in[project.optional-dependencies].dev, and console entry points in[project.scripts]. - Under static
[project.dependencies],[tool.poetry.dependencies]only supplies alternate sources. A package listed there but absent from[project.dependencies]is not installed. Declare the package name in[project.dependencies]and use[tool.poetry.dependencies]only for its path, Git, or URL source. - Never repair a Poetry environment by installing packages directly with
pip. Fix the manifest, regenerate the lock file, and runpoetry installso the environment and lock remain consistent. - Configure strict Pyright, pytest with automatic asyncio support, and Black with Python targets inferred from the full
[project.requires-python]range. - Keep that range's upper bound at the version the project actually runs. Black formats for the newest release the range admits, then verifies the result by parsing it with the running interpreter, so a bound reaching past that interpreter makes every run emit a parse warning for a grammar it cannot read.
- Set one line length and give every tool that wraps or measures lines the same value, so the formatter and the linters cannot disagree about what is too long.
- Keep the Poetry build system at the end of
pyproject.toml:
[build-system]
requires = ["poetry-core>=2.0.0"]
build-backend = "poetry.core.masonry.api"
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.

poetry is a cursor rule published in the GitHub repository julien777z/agent-sync-action (9 stars, last pushed 3d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 854 tokens. 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.
