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 | $0.00036 | $0.00321 |
| Opus 5 | $0.00018 | $0.00161 |
| Sonnet 5 | $0.00007 | $0.00064 |
| Haiku 4.5 | $0.00004 | $0.00032 |
Grade A, and why
tmcp-incident-postmortem 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 9d 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 Incident Postmortem
Status: experimental. This workflow remains shipped and callable, but its public contract may change.
Use this skill when the user asks for an incident review, postmortem, outage analysis, regression analysis, root-cause writeup, failure timeline, or follow-up remediation plan.
Use systematic debugging first when the failure has not been reproduced or isolated. Use TMCP after there is enough evidence to turn the event into a durable packet.
Workflow
- Gather evidence: observed impact, timeline, logs, commits, CI output, rollback notes, reproduction notes, affected users/systems, and follow-up constraints.
- Invoke
tmcp_explainfor the postmortem packet when available. - Invoke
expert_rubric_review_planfor the causal audit and remediation plan. - If MCP tools are unavailable, run from the TMCP plugin root:
node scripts/tmcp_launcher.mjs review-plan "Create an incident postmortem packet for <project>" --project-path "<project-path>" --evidence-json '<json>' --write-artifacts
Output Contract
Produce or cite:
- TMCP packet and
substance_check. - Incident timeline and evidence gaps.
- Root cause and contributing factors.
- Blast radius and verification gaps.
- Ordered follow-up remediation plan.
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-incident-postmortem is a skill published in the GitHub repository jakyeamos/tmcp (0 stars, last pushed 16d ago), licensed MIT. It adds 36 tokens to every session and 321 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.
