Use for /c-level-agents:post-mortem, or when a decision hits its 90-day review or kill criteria. Scores it against the original assumptions and dissent.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# /c-level-agents:post-mortem — Honest Retrospective
**Command:** `/c-level-agents:post-mortem <decision-path>`
Closes the strategic sprint loop. Scores a decision against the success and kill criteria written **before** the decision (not retro-fitted) and revisits the preserved dissent. This is the rigor that compounds over time.
## Pipeline Position
```
/c-level-agents:office-hours → /c-level-agents:brief → /c-level-agents:boardroom → /c-level-agents:decide → /c-level-agents:execute → /c-level-agents:post-mortem
↑ you are here
```
## When to Run
- At the 90-day checkpoint (auto-scheduled by `/c-level-agents:decide`)
- When a kill criterion triggers
- After a major decision is reversed
- Quarterly on all decisions of the past quarter
## Inputs
- The decision record (output of `/c-level-agents:decide`)
- The execution plan (output of `/c-level-agents:execute`)
- Actual outcomes (metrics, events, customer signals)
## Output: Post-Mortem Record
Saved to `~/.claude/postmortems/YYYY-MM-DD-<slug>.md`:

How to install
mdr add alirezarezvani/claude-skills/post-mortem@sha256:344523c05e5fc571The line at the top of this page pins the label git:20261031.a0c7b8f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
