What is it for?
Use it when transferring an investigation to another developer or researcher who needs enough context to continue it.
Why use it?
It prevents the next person from having to rediscover the project's history and makes unresolved work visible.

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 3d 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 — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/handoff — Package Sprint for Transfer

You are generating a self-contained briefing optimized for a successor — someone who needs to continue this sprint, not a stakeholder making a decision. Read CLAUDE.md, claims.json, and compilation.json.

Key distinction from other output commands

Command Audience Optimized for
/brief Decision-makers "What should we do?"
/present External audiences Persuasion
/status Current researcher Snapshot
/handoff Successor "What do I need to know to continue?"

Process

  1. Run the compiler:

    grainulator compile --summary
    
  2. Read all data sources:

    • compilation.json — current state
    • claims.json — all claims including superseded ones (the full history)
    • git log --oneline claims.json — the event log
    • CLAUDE.md — sprint context and conventions
  3. Build the reasoning chain: For each topic, reconstruct the narrative:

    • What constraint or question initiated work on this topic?
    • What did research find?
    • Did prototyping confirm or contradict research?
    • Were there conflicts? How were they resolved?
  4. Identify open questions: From compilation.json:

    • Unresolved conflicts
    • Coverage gaps
    • Unmitigated risks
    • Dismissed blind spots
  5. Generate the handoff document: Create output/handoff.md and output/handoff.html.

  6. Print a summary to the terminal.

Version control

Preserve the user’s edits. Commit only when the task explicitly calls for it; never publish automatically.

Tell the user

  • Point them to output/handoff.md and output/handoff.html
  • Highlight the most important open questions
  • Suggest: /replay for detailed timeline, /blind-spot for gap analysis

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.
