What it does

Nw Post Mortem Framework is an agent skill from nWave-ai/nWave. Blameless post-mortem structure, incident timeline reconstruction, response evaluation, and organizational learning

Its SKILL.md is about 760 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in DevOps & Cloud, covering Runbooks and postmortems. The repository describes itself as: AI agents that guide you from idea to working code, with you in control at every step. The licence is MIT.

When your agent uses it

  • Tasks that involve Runbooks and postmortems

Example prompts

  • “/nw-post-mortem-framework”

Workflow steps

2 steps, taken from the first numbered list in SKILL.md.

  1. Monitoring alerts/dashboards (timestamps) | 2. Deployment logs/CI-CD records
  2. Communication channels (Slack, email, incident) | 4. VCS (commits, merges, deploys) | 5. User reports/support tickets

What it can do on your machine

Read from SKILL.md and the folder at commit da401a8. 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

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).

    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

Nw Post Mortem Framework loads about 759 tokens when it runs. Until then it costs about 35 tokens; SKILL.md has 173 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~35
When it runs · the whole SKILL.md, loaded when a task matches
~759

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); files beside SKILL.md are not scanned.

Post-Mortem Framework

Principles

  • Blameless: focus on systems/processes, not individuals. People make reasonable decisions given available info.
  • Evidence-based: every finding backed by logs, metrics, or documented actions
  • Action-oriented: every finding produces concrete, assigned action item
  • Learning-focused: capture what worked alongside what failed

Post-Mortem Document Structure

markdown
# Post-Mortem: [Incident Title]

**Date**: [incident date]
**Duration**: [start to resolution]
**Severity**: [P0-P3]
**Author**: [analyst]

## Summary
[2-3 sentence overview: what happened, impact, resolution]

## Timeline
| Time | Event | Source |
|------|-------|--------|
| HH:MM | [event] | [log/metric/report] |

## Impact
- Users affected: [number/percentage]
- Duration of impact: [time]
- Business impact: [quantified if possible]
- Systems affected: [list]

## Root Cause Analysis
[5 Whys analysis with evidence at each level]

## Detection and Response
- Time to detect: [duration] -- [how detected]
- Time to respond: [duration] -- [first action]
- Time to mitigate: [duration] -- [mitigation applied]
- Time to resolve: [duration] -- [permanent fix]

## What Went Well
- [positive observations about detection, response, recovery]

## What Could Be Improved
- [areas where detection, response, recovery fell short]

## Action Items
| ID | Action | Owner | Priority | Due Date |
|----|--------|-------|----------|----------|
| 1 | [specific action] | [team/person] | [P0-P3] | [date] |

## Lessons Learned
- [key takeaways for the organization]

Incident Timeline Reconstruction

Sources
  1. Monitoring alerts/dashboards (timestamps) | 2. Deployment logs/CI-CD records
  2. Communication channels (Slack, email, incident) | 4. VCS (commits, merges, deploys) | 5. User reports/support tickets
Quality Checks

Events chronological with verified timestamps | gaps >5 min noted/explained | decision points identified with available info | causal relationships noted

Response Effectiveness Evaluation

Detection

Detected by monitoring or users? | Duration onset-to-detection? | Existing alerts relevant? Missing?

Escalation

Right team at right time? | Procedures followed? | Communication clear to stakeholders?

Resolution

Mitigation effective? | Rollback considered/viable? | Duration mitigation-to-permanent-fix?

Organizational Learning

Knowledge Capture

Document root causes as reusable patterns | update runbooks | share in retrospectives

Process Improvements

Update monitoring/alerting per detection gaps | revise deployment per rollback effectiveness | strengthen testing for failure scenario

Action Item Tracking

Every item has owner + due date | track in standups/sprint reviews | verify effectiveness post-deployment
