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-create 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 today.

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

Generate a structured handoff document from our current conversation and save it to claudedocs/handoffs/handoff_YYYYMMDD_HHMMSS.md (or use the filename provided as $ARGUMENTS[0] if given).

Create the claudedocs/handoffs/ directory if it does not exist.

Document Structure

Include exactly these sections:

# Handoff: [Task Name] - [YYYY-MM-DD HH:MM]

## Task

[One sentence: what is being accomplished]

## Scope

[What needs to be done. Be specific about boundaries: what is in scope and what is explicitly out of scope]

## Files

[All relevant files touched or needed. Format: `path/to/file:line` when a specific line matters]

- `src/auth/middleware.ts:45` - token validation logic
- `tests/auth.spec.ts` - test suite for this change
- `docs/api.md` - needs update after implementation

## Discoveries

[Key findings and insights from the work so far. Things the next agent needs to know that are not obvious from the code]

- [Discovery 1]
- [Discovery 2]

## Work Done

[Completed tasks. Append-only: never remove prior entries. Include commit hashes when available]

- [x] Task A completed (commit: abc1234)
- [x] Task B completed

## Status

[Current state: what is done, what remains, test status, blockers]

## Next Steps

[Actionable checklist of remaining tasks, in order]

1. [ ] Step 1
2. [ ] Step 2
3. [ ] Step 3

## Code

[Relevant code snippets with context. Focus on the parts a resuming agent needs to understand immediately]

\`\`\`typescript
// Key implementation detail
\`\`\`

Rules

  • Keep it under 600 words total. A resuming agent should be able to load this and proceed within 30 seconds of reading.
  • Use path/to/file:line format for all file references. Line numbers matter.
  • "Work Done" is append-only. Never remove previous entries.
  • Do not include the full git diff or full file contents. Include only the code snippets that are non-obvious.

After saving, confirm the file path.

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.
