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 | $0.00125 | $0.06473 |
| Opus 5 | $0.00063 | $0.03236 |
| Sonnet 5 | $0.00025 | $0.01295 |
| Haiku 4.5 | $0.00013 | $0.00647 |
Grade A, and why
handoff-docs 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 — 485 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Handoff Docs Skill
When to use
- The user asks to save a spec, design doc, ADR, guide, or note so it survives across sessions
- The user wants to import an existing pile of Markdown files (e.g. a
wiki/orspecs/directory) into structured document management - You need to read a specific section of a large document without pulling the whole thing into context
- You need to trace how documents relate to each other (parent/child hierarchy, or semantic links like "this design implements that spec")
- A document should be linked to one or more tasks so it surfaces automatically while that task is being worked on
If the knowledge is a short, standalone lesson/rule/convention/gotcha (< 1 page,
no internal sections), use handoff-memory instead — see "Memory vs Documents"
in skills/handoff-memory/SKILL.md for the boundary.
Development Flow Integration
Document management is NOT just for explicit user requests. It activates automatically during the standard development cycle:
When writing a spec or design
After writing/updating a specification or finishing a /design-review session
(wiki/ or tmp/), immediately:
- Start from a template (see "Templates" below) instead of a blank document.
handoff_doc_save(slug="unique-spec-slug", title=..., body=..., doc_type="spec", task_ids=[...])handoff_doc_verify(doc_id=..., action="generate")to create the verification matrix
When starting a task
Before implementation, fetch related specs:
handoff_doc_query(task_id="<task-id>")— surfaces linked documents automatically- Review the verification matrix:
handoff_doc_verify_status(doc_id=...)
When implementation is complete
Mark verified sections:
handoff_doc_verify(doc_id=..., action="check", fragment_seq=N)for each completed sectionhandoff_doc_verify(doc_id=..., action="set_refs", fragment_seq=N, impl_refs=[...])to record implementation locations
When reviewing
Check readiness:
handoff_task_checklist(task_id=..., action="view")— combined readiness view
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-docs is a skill published in the GitHub repository alphaelements/handoff-mcp (0 stars, last pushed 5d ago), licensed MIT. It adds 125 tokens to every session and 6,473 once invoked, about $0.0006 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 2026-08-31.
