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 | $0.00043 | $0.00264 |
| Opus 5 | $0.00022 | $0.00132 |
| Sonnet 5 | $0.00009 | $0.00053 |
| Haiku 4.5 | $0.00004 | $0.00026 |
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 11d 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
Write or update a handoff document so the next agent with fresh context can continue.
Steps
- If
HANDOFF.mdexists in the project root, read it first. - Do not duplicate content already in PRDs, plans, ADRs, issues, commits, or diffs — reference them by path or URL.
- Write or update
HANDOFF.mdin the project root with:- Goal — what we're trying to accomplish
- Current Progress — what's done (link commits/PRs)
- What Worked — approaches that succeeded
- What Didn't Work — dead ends, so they aren't retried
- Next Steps — concrete action items
- Suggested skills — which skills the next session should load, if any
- If the user passed arguments, tailor the doc to that focus.
- Tell the user the path so they can start a fresh conversation with 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 is a skill published in the GitHub repository laguagu/claude-code-nextjs-skills (62 stars, last pushed 8d ago), licensed MIT. It adds 43 tokens to every session and 264 once invoked, about $0.0002 per session on Opus 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 2026-08-30.
