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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00053 | $0.00565 |
| Opus 5.5 | $0.00021 | $0.00226 |
| Sonnet 5.5 | $0.00011 | $0.00113 |
| Haiku 4.5 | $0.00005 | $0.00056 |
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 1mo 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
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]

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:lineformat 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.
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.

handoff-create is a skill published in the GitHub repository FlorianBruniaux/claude-code-plugins (42 stars, last pushed 1mo ago), licensed MIT. It adds 53 tokens to every session and 565 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-04.
