handoff

handoff is a cursor rule for Cursor from xiaomaimuchanyiyiba/agent-handoff. It costs 38 tokens per session (536 once invoked), scanned A, original, MIT.

A project handover system that records the current state of work in dated Markdown files. A HANDOFF.md link points to the newest handover.

In plain words
What is it for?
Handing over projects, subprojects, tasks, or archived work while keeping a history of previous handovers.
Why use it?
It gives the next person or agent the project context, setup details, status, and next steps without requiring a fresh explanation.

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

handoff 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 6d 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

Handoff — Project Handover

Write handoff docs under .handoff/ directory, with HANDOFF.md as a symlink to the latest. The next person should need zero follow-up questions.

Artifact Layout

.handoff/
├── 2026-05-11.md         # timestamped entries (YYYY-MM-DD)
├── 2026-05-11.001.md     # subsequent entries same day
└── 2026-05-10.md
HANDOFF.md -> .handoff/2026-05-11.md   # symlink to latest
  • .handoff/ is gitignored
  • HANDOFF.md symlink is updated on every write

Mode Detection

  • No .handoff/ files + no HANDOFF.md → Wave mode: write a new handoff
  • .handoff/ exists or HANDOFF.md exists + user says "take over" → Land mode
  • Exists + unclear intent → Ask

Backward compat: standalone HANDOFF.md (not symlink) is detected as legacy — migrate on first Wave.

Wave Mode — Write Handoff Doc

  1. Create .handoff/ if missing
  2. Generate filename: YYYY-MM-DD.md (first today) or YYYY-MM-DD.001.md etc.
  3. Write content to .handoff/<filename>
  4. ln -sf .handoff/<filename> HANDOFF.md
  5. Add .handoff/ to .gitignore if missing

Core sections: Project Overview, Startup, Directory Structure, Current Status, Next Steps. Supplementary sections: as needed (DB, API, routes, agents, etc.).

Match the user's language. Mark unknowns as ⚠️ TBD.

Land Mode — Take Over

  1. Find latest: .handoff/ files sorted by name desc, or follow HANDOFF.md symlink
  2. Read all referenced docs
  3. Report findings first, wait for confirmation
  4. Execute TODOs by priority, create new timestamped handoff after each change

Universal Principles

  • No guessing, no sugarcoating
  • Analyze before acting
  • Keep the trail — new file per update, never overwrite history
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.
