Token cost

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.

Security

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 — 206 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Handoff Docs Skill

Structured project documents under .handoff/docs/: one Markdown file per document, indexed by section, searchable, linked to tasks and to each other.

  • Per-tool parameters: references/doc-tools.md
  • Section verification matrix and doc_req_* requirements: references/verification-matrix.md
  • V-model layer documents (requirements → specs → tests with coverage, suspects, approval): the handoff-trace skill (overview, setup) and the handoff-requirements skill (how to write items)

When to use

  • The user asks to save a spec, design, plan, ADR, guide or note so it survives across sessions — or you write one during development
  • Importing an existing directory of Markdown (specs/, docs/) at once
  • Reading one section of a large document without loading all of it
  • Following how documents relate (parent/child, "implements", "supersedes")
  • Linking a document to tasks so it surfaces while those tasks are worked on

A short standalone lesson/rule/gotcha (under a page, no sections) belongs in project memory instead — see the handoff-memory skill and "Memory vs Documents" below.

Choose a tracking style first

you need use
keep a document, read and search it plain document (doc_save)
tick off sections of a spec as implemented section matrix (doc_verify, see verification-matrix.md)
a list of individually tracked requirements from a requirement table section matrix + doc_req_import (verification-matrix.md)
requirements linked to specs and tests, coverage, change impact (suspects), approval V-model layer document — doc_save(layer=...), see handoff-trace

A layer document's items come from its body headings; the section matrix's add_item / set_priority / set_refs(test_refs) and doc_req_import are refused on it. Pick one style per document.

If the project uses the V-model ([trace] profile is set — check handoff_get_config), save specs and designs with a layer, or enable [trace] auto_layer so doc_save infers one: spec → requirement, design → detailed_spec, plan → detailed_spec (override with [trace] plan_default_layer); adr / guide / note never get one. An explicit layer always wins ("" clears it and suppresses inference for that call). For layers the table does not cover (basic_spec, acceptance, …), always pass layer explicitly.

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.
