run-retrospective

run-retrospective is a skill for Claude Code from tomzx/agents. It costs 36 tokens per session (469 once invoked), scanned A, original, MIT.

A retrospective guide for recording what to keep, stop, and start after an initiative, sprint, or cancelled effort. A retrospective turns experience into reusable team knowledge by looking for root causes.

In plain words
What is it for?
Use it to create a learning record, identify root causes, and turn lessons into owned follow-up actions.
Why use it?
It prevents teams from repeating mistakes or losing useful lessons when work ends. It connects lessons to the decisions and assumptions that shaped the work.

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

run-retrospective 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 6d 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

Run Retrospective

Turns a completed initiative, a sprint, or a killed bet into organizational knowledge. Produces a learning record in .pdlc/learnings/. A kill without a retrospective is waste — the point of killing is to learn cheaper than building would have taught.

Prerequisites

  • Apply the shared PDLC conventions in skills/pdlc/references/shared.md.
  • A concluded initiative (shipped, iterated, or killed), or a sprint boundary.

Steps

  1. Frame the scope: which initiative or period, and what outcome occurred (shipped, iterated, killed).
  2. Capture what to keep (what worked and should be repeated), what to stop (what to never do again), and what to start (new actions to try).
  3. For each item, name the root cause, not just the symptom. "We were slow" is a symptom; "discovery and build ran in series with no handoff contract" is a root cause.
  4. Tie each learning back to the artifact chain: which assumption, decision, or gate should have caught this earlier?
  5. Convert the strongest start/stop items into concrete next actions with owners (feed the roadmap or a new initiative).
  6. Write the record to .pdlc/learnings/N-<slug>.md.

Output Format

Use the template at skills/pdlc/templates/learning.md. Keep/stop/start sections, each item with root cause and (where relevant) a traceable artifact link.

Outcome

If $OUTCOME_YAML is set, emit verdict: captured.

Completion Checklist

  • Keep / stop / start each populated
  • Each item has a root cause, not just a symptom
  • Learnings traced back to the artifact chain where possible
  • Strongest items converted to owned actions

Next Step

Feed owned actions into build-roadmap or a new /pdlc discover cycle.

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.
