nw-post-mortem-framework

nw-post-mortem-framework is a skill for Claude Code from nWave-ai/nWave. It costs 26 tokens per session (691 once invoked), scanned A, original, MIT.

A blameless framework for documenting and learning from incidents, including a timeline, impact, root-cause analysis, and response review. A post-mortem is a written account made after a failure or outage.

In plain words
What is it for?
Use it to reconstruct incidents from logs and metrics, record what happened, assess detection and response, and assign corrective actions.
Why use it?
It turns an incident into evidence-based lessons and concrete follow-up actions without focusing on individual blame.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

nw-post-mortem-framework 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 1mo 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.

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

# 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]

|------|-------|--------|
| 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 |

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.
