Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00035 | $0.00298 |
| Opus 5 | $0.00017 | $0.00149 |
| Sonnet 5 | $0.00007 | $0.00060 |
| Haiku 4.5 | $0.00003 | $0.00030 |
Grade A, and why
tmcp-agent-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 10d 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
TMCP Agent Handoff
Status: experimental. This workflow remains shipped and callable, but its public contract may change.
Use this skill when the user asks for a handoff, resume packet, continuity note, pause-work summary, next-agent context, or durable state packet.
Do not use it as a generic summary if no future worker needs to act on the output.
Workflow
- Gather evidence: current goal, git state, files changed, decisions made, commands run, test results, blockers, open questions, and next actions.
- Invoke
tmcp_explainfor the handoff packet when available. - If a scored audit is needed, invoke
expert_rubric_review_planfor handoff completeness. - If MCP tools are unavailable, run from the TMCP plugin root:
node scripts/tmcp_launcher.mjs review-plan "Create an agent handoff and continuity packet for <project>" --project-path "<project-path>" --evidence-json '<json>' --write-artifacts
Output Contract
Produce or cite:
- Current-state packet.
- Decisions and constraints.
- Changed/touched surfaces.
- Verification already run.
- Blockers, open questions, and next commands.
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.

tmcp-agent-handoff is a skill published in the GitHub repository jakyeamos/tmcp (0 stars, last pushed yesterday), licensed MIT. It adds 35 tokens to every session and 298 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 2026-08-31.
