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 | $0.00040 | $0.00300 |
| Opus 5.5 | $0.00016 | $0.00120 |
| Sonnet 5.5 | $0.00008 | $0.00060 |
| Haiku 4.5 | $0.00004 | $0.00030 |
Grade A, and why
handoff-resume 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
Read and load the handoff document at $ARGUMENTS[0].
Steps
-
Read the file at the provided path. If the path does not exist, list files in
claudedocs/handoffs/and ask the user which one to load. -
Parse and confirm:
- Task and scope
- Files involved (with line numbers)
- Key discoveries
- Work completed so far
- Current status
- Next steps (ordered)
-
Confirm understanding: Summarize what you have loaded in 3-5 bullet points. Ask: "Should I proceed with the next step, or do you want to adjust the plan first?"
-
Do not start working until the user confirms. The confirmation step is mandatory.
Notes
- If the handoff file references commits (
commit: abc1234), note them but do not re-run the work. - If next steps are unclear or conflicting, flag it before proceeding.
- The "Work Done" section is the authoritative record of what has been completed. Trust it.
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-resume is a skill published in the GitHub repository FlorianBruniaux/claude-code-plugins (42 stars, last pushed 1mo ago), licensed MIT. It adds 40 tokens to every session and 300 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings.
