What it does
Postmortem is an agent skill from Dimon94/skills. Recall or record confirmed reusable failure lessons. Use after a verified recurrence, review escape, failed gate, or explicit user request.
Its SKILL.md is about 430 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including scripts (for example `agents/openai.yaml` and `scripts/postmortem-contract.js`).
It sits in DevOps & Cloud, covering Runbooks and postmortems. The repository describes itself as: 个人 agent skill 库 — skills/ 为唯一真相源，agent 目录经 symlink 消费.
When your agent uses it
- Tasks that involve Runbooks and postmortems
Example prompts
- “/postmortem”
Requirements
- Node.js
What it can do on your machine
Read from SKILL.md and the folder at commit 9e8d3b3. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (JavaScript), which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Postmortem loads about 434 tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 193 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 193 words (~434 tokens).
“postmortem owns reusable failure memory. It does not own workflow state, review findings, remote delivery, or ordinary failure logs.”
