retro

retro is a skill for Claude Code from Maximumsoft-Co-LTD/claude-flightdeck. It costs 110 tokens per session (2,244 once invoked), scanned A, original, MIT.

A workflow for closing a sprint—a fixed period of planned development work—and recording what the team learned.

In plain words
What is it for?
Use it to close sprints, write retrospectives, promote lessons into rules, and archive old sprint records.
Why use it?
It turns completed work and lessons into immediate cleanup and possible project rules instead of leaving problems unresolved.

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

retro 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 5d 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.

How it starts

The opening of the file, as written. The whole thing — 156 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/retro — Sprint Close · Rule Ratification · Archive

Announce: Using /retro …

The retro fixes problems immediately — it does not just document them. Old /ratify-rules and /archive are gone; use /retro ratify and /retro archive.

Token budget

  • One Read of docs/project/sprints/S<N>/tasks.md (limit: 400) — the primary input (the board holds the live mini-retros).
  • One Read of docs/project/backlog.md — for the audit + the highest F#### ID.
  • scripts/backlog.sh sweep + index — sprint-close backlog hygiene (closed ## Active rows → cold archive; index regen). Deterministic bash, 0 LLM tokens.
  • Grep for everything else (lesson recurrence, candidate rules, sprint scan).
  • Grep one section of ../../rules/brain-hot.md (ratify mode) — never full-Read.

Mode 1 — /retro (sprint close + auto-chain ratify)

The live per-task mini-retros inside docs/project/sprints/S<N>/tasks.md are the PRIMARY input. The full retro lands in docs/project/sprints/S<N>/retro.md. Two HARD gates block close.

  1. Read the boarddocs/project/sprints/S<N>/tasks.md. Missing/empty = process loss; flag it in the retro.
  2. Read docs/project/backlog.md — note the highest existing F####; open rows are candidates for reconciliation at the audit gate.
  3. Scan git log since sprint open for each touched repo.
  4. Cross-cutting drift — grep for invariants (contract drift, schema drift, observability gaps). Each drift = a finding.
  5. Gather top wins + top issues (ask the user, or "auto").
  6. Create docs/project/sprints/S<N>/retro.md from the template below.
  7. Classify every action itemfix NOW (this commit) vs defer (backlog row or follow-up).
  8. Execute every "fix now" item — do NOT commit the retro until they land (update affected skills + rules in the same commit).

HARD GATE — Backlog audit (drift blocks close):

scripts/backlog.sh check        # Status enum + size cap — must exit 0
scripts/backlog.sh reconcile    # advisory: wip rows that look already-closed in S<N>

check must pass. Resolve every reconcile flag (set genuinely-shipped rows to done S<N>; the sweep below moves them out). Cite: Backlog audit: check ✓ · <N> reconcile flag(s) resolved.

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.
