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 | $0.00027 | $0.00318 |
| Opus 5 | $0.00014 | $0.00159 |
| Sonnet 5 | $0.00005 | $0.00064 |
| Haiku 4.5 | $0.00003 | $0.00032 |
Grade A, and why
cancel-jeffy 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.
What it actually says
Cancel Jeffy
Stop the Jeffy loop in this project by removing the loop state file the Stop hook reads.
- Project root is the directory Claude Code was started in, not wherever the shell currently sits: the Bash tool's cwd persists across calls and may have drifted into a subdirectory that holds its own orphaned state file from another session. Always check state files with absolute paths anchored at the project root, never bare relative ones.
- Check
<project-root>/.claude/jeffy-loop.local.md. If it exists, read its frontmatter and report its session_id, iteration, and started_at, then delete the file and confirm the loop is cancelled. Once the file is gone the Stop hook lets the session end normally. - Also check
<project-root>/.claude/ralph-loop.local.md: it belongs to the ralph-loop plugin's engine or a pre-2.0 Jeffy. If it exists, report the same frontmatter fields and delete it too, so no legacy loop keeps re-feeding. - If neither file exists, report that no Jeffy loop is active in this project and stop.
- Remind the user that PLAN.md, BACKLOG.md, and JOURNAL.md are untouched: the loop picks up where it left off the next time they run /jeffy.
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.

cancel-jeffy is a skill published in the GitHub repository lenamonj/jeffy-loop (8 stars, last pushed today), licensed MIT. It adds 27 tokens to every session and 318 once invoked, about $0.0001 per session on Opus 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.
