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 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.

Handoff

Goal

Create a compact continuation artifact that lets another agent resume the task without re-reading the entire thread or losing important decisions.

Trigger conditions

  • The user asks for a handoff, checkpoint, resume note, or context summary.
  • The current thread is long or close to compaction.
  • Work must pause before validation, review, merge, or release.

When to use

  • Use when another agent, thread, or future session must continue the same work.
  • Use before compacting a long-running implementation or review thread.

When not to use

  • Do not use for a final answer when the task is complete.
  • Do not use to replace source files, issues, PR descriptions, or validation logs.

Inputs to inspect

  • Latest user instruction, current objective, changed files, validation commands, failures, and blockers.
  • Use git status --short and git diff --stat when working inside a repository.

Rules

  • Reference files, diffs, PRs, issues, and reports by path or URL instead of duplicating content.
  • Include only decisions, evidence, validation status, blockers, and next steps needed to continue.
  • Separate confirmed facts from assumptions.
  • Keep secrets out of the handoff.

Workflow

  1. Identify the objective and the latest user instruction.
  2. Summarize decisions and why they were made.
  3. List changed files or active work areas.
  4. Record commands run and their outcomes.
  5. Name blockers, risks, and missing approvals.
  6. End with the next concrete action.

Commands

Useful commands before writing:

git status --short
git diff --stat
git log --oneline -5

Safety rules

  • Do not include tokens, credentials, or sensitive snippets.
  • Do not imply validation passed unless it was run and succeeded.
  • Do not bury approvals required for destructive or remote actions.

Assets

Use assets/handoff-template.md when the user wants a file-based handoff.

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.

Changes

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.
