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.

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 | $0.00048 | $0.00580 |
| Opus 5 | $0.00024 | $0.00290 |
| Sonnet 5 | $0.00010 | $0.00116 |
| Haiku 4.5 | $0.00005 | $0.00058 |
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 — 35 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Write a handoff document summarising the current conversation (or a specific side-topic that surfaced) so a fresh agent can continue the work without re-deriving context.
Where to save it
Check .ab-method/structure/index.yaml first. In an AB Method project, handoffs are a tracked artifact, not throwaway scratch — save to docs/handoffs/[slug].md (the location the index defines). The slug is a short kebab-case summary of the topic, e.g. rate-limit-redis-vs-token-bucket.md.
If the project is not an AB Method project (no .ab-method/), fall back to the temporary directory of the user's OS — do not pollute the workspace.
The spin-off-mid-grill case
The most common trigger here: you are in the middle of a grill-with-docs / grill-me session and a tangent emerges that clearly deserves its own task. Do not derail the current grill. Instead:
- Write the tangent up as a handoff under
docs/handoffs/. - Capture only the tangent — the question that opened it, the constraints already established, the decisions still open, and why it was deferred.
- Tell the user: "Captured
<slug>as a handoff — resume it any time with/create-task-from-handoff <slug>." Then continue grilling the original topic.
What the document must contain
- Goal — what the next session is meant to accomplish (use the passed argument verbatim if given).
- Context — the minimum a fresh agent needs: what's been decided, what's still open, what was explicitly ruled out and why.
- Suggested skills — which skills the next agent should invoke (e.g.
grill-with-docs,tdd). For a deferred-task spin-off, the suggested next step is/create-task-from-handoff. - References — link to existing artifacts (PRDs, plans, ADRs, issues, commits, diffs, the parent task's
progress-tracker.md) by path or URL. Do not duplicate their content.
Rules
- Do not duplicate content already captured elsewhere — reference it by path or URL instead.
- Redact any sensitive information (API keys, passwords, PII).
- If the user passed arguments, treat them as a description of what the next session will focus on and tailor the doc accordingly.
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.
- 3d ago First seen · 35 lines · 48 tokens per session scan A 21bc23eb9416
handoff is a skill published in the GitHub repository ayoubben18/ab-method (187 stars, last pushed 1mo ago), licensed MIT. It adds 48 tokens to every session and 580 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.
