retro

retro is a skill for Claude Code, Codex from AlanHuang168/AI-Project-Workflow. It costs 0 tokens per session (592 once invoked), scanned A, original, MIT.

A project retrospective guide: a structured review of what happened after a project or delivery. It records results, deviations, root causes, reusable work and improvements for the next iteration.

In plain words
What is it for?
Use it after deployment, or when skipping deployment has been approved, to review project documents and code and update the retrospective and workflow state.
Why use it?
It turns scattered project experience into documented lessons instead of losing useful information after delivery. It also separates observed improvements from changes that still need team approval.

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 9d 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.

name: retro description: Summarize outcomes, deviations, root causes, reusable assets, and improvement actions. Use when the project is complete, when delivery needs a retrospective, or when the user invokes /retro. version: 1.0.0 stage: retro

Goal

Review the full workflow and capture outcomes, deviations, root causes, reusable assets, and improvements for the next iteration.

Use Cases

  • The user invokes /retro.
  • The user asks for a project retrospective.
  • The project needs a delivery summary.

Preconditions

  • deploy is complete, or the user explicitly approves skipping deployment and records the reason.
  • Upstream documents and code are readable.

Required Context

  • AGENTS.md
  • .ai-workflow/state.json
  • core/templates/RETRO.template.md
  • docs/PRD.md
  • docs/ARCH.md
  • docs/SDD.md
  • docs/TEST.md
  • docs/REVIEW.md
  • docs/DEPLOY.md, if present
  • Relevant source and test files

Inputs

  • Full project context.
  • User feedback about results, quality, time, and risk.

Allowed Changes

  • docs/RETRO.md
  • .ai-workflow/state.json
  • Optional candidate improvements for team rules, but only after user confirmation.

Steps

  1. Read workflow state, upstream documents, review report, deployment guide, and code.
  2. Summarize completed and incomplete work.
  3. Compare plan versus actual outcome and analyze root causes.
  4. Record what went well, problems, improvement actions, and reusable assets.
  5. Identify next-version recommendations and priorities.
  6. Write docs/RETRO.md.
  7. Update workflow state: documents.retro = "complete", add retro to completedStages, set currentStage = "retro", and update the timestamp.

Outputs

  • docs/RETRO.md
  • Updated .ai-workflow/state.json

Acceptance Criteria

  • RETRO includes outcome, plan versus actual, what went well, problems and root causes, improvement actions, and reusable assets.
  • Incomplete work and deviations are recorded honestly.
  • The retrospective is not only praise or a chronological log.

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.
