Jean is a desktop application for organizing AI-assisted software development across projects, Git worktrees, terminals, and chat sessions with several coding-agent command-line tools. Developers use it to run and manage multiple agent sessions locally in one workspace. Its catalogue add-ons support workflows performed inside Jean.
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00015 | $0.00015 |
| Opus 5.5 | $0.00006 | $0.00006 |
| Sonnet 5.5 | $0.00003 | $0.00003 |
| Haiku 4.5 | $0.00002 | $0.00002 |
Grade A, and why
main 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.

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.

main is a cursor rule published in the GitHub repository coollabsio/jean (1,336 stars, last pushed today), licensed Apache-2.0. It adds 15 tokens to every session, about $0.0001 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 2026-08-30.
Other cursor rules, from other repositories
cd
GitHub Actions CD - called by release.yml after the tag, no push-tags trigger, cf workers versions create then a 100% deployment in deployOrder, scoped API token on the production environment, GitHub-owned deployment record.
resume
Resume a checkpointed session from the pushed handoff and continue where it left off. Use on "resume", "pick up where I left off", "continue from the handoff", or starting cold on another device — pulls, reads .pause/handoff.md, and keeps going.
commit
Create well-formatted commits with conventional commit messages and emojis.
add-to-changelog
Update the project's CHANGELOG.md file with a new entry.
bug-fix
Streamline bug fixing workflow from issue creation to pull request.
changelog-generator-manual
This rule generates a comprehensive changelog.md file by analyzing all git tags and commits, creating a chronological record of all project changes with proper semantic versioning structure. The changelog.md file is stored at the root of the project.
