cancel-jeffy

cancel-jeffy is a skill for Claude Code, Codex from lenamonj/jeffy-loop. It costs 27 tokens per session (318 once invoked), scanned A, original, MIT.

A command that stops the active Jeffy improvement loop in a project. Jeffy is an automated work cycle that continues a task through repeated sessions.

In plain words
What is it for?
Use it to remove the loop's state files, report the active session details, and confirm that the loop has been cancelled.
Why use it?
It lets you end that cycle without removing the project's planning and journal files.

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.

Security

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.

  1. 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.
  2. 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.
  3. 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.
  4. If neither file exists, report that no Jeffy loop is active in this project and stop.
  5. 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.
Changes

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.
