retro

retro is a command for Claude Code from CrashBytes/claude-role-skills. It costs 6 tokens per session (529 once invoked), scanned A, original, Apache-2.0.

A structured meeting guide for reviewing a completed development sprint, which is a planned period of team work. It supports formats such as Start/Stop/Continue, 4Ls, Sailboat, Timeline, and Fishbone.

In plain words
What is it for?
Use it to run a sprint retrospective, with an optional format in the request. It sets the stage, asks discussion questions, groups feedback where appropriate, and can use project metrics when a project-management connection is available.
Why use it?
It gives the team a clear way to discuss what happened, what helped, what caused problems, and what to change. Without a format, retrospectives can become unfocused or skip important issues.

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 7d 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.

Arguments

Requested format: $ARGUMENTS

Workflow

  1. Select format

    • If a format is specified, use it
    • If not specified, default to Start/Stop/Continue (most universal)
    • Available formats: start-stop-continue, 4ls, sailboat, timeline, fishbone
  2. Set the stage (2 min)

    • State the Prime Directive: "Regardless of what we discover, we understand and truly believe that everyone did the best job they could, given what they knew at the time, their skills and abilities, the resources available, and the situation at hand."
    • If a project management MCP server is connected, pull the sprint metrics (velocity, burndown, completed vs committed)
  3. Run the format

    Start/Stop/Continue:

    • Ask: What should we START doing? What should we STOP doing? What should we CONTINUE doing?
    • Generate 3-5 prompting questions for each category based on common team patterns

    4Ls (Liked, Learned, Lacked, Longed For):

    • Ask for items in each L category
    • Group related items across categories

    Sailboat:

    • Wind (what propels us forward), Anchor (what holds us back), Rocks (risks ahead), Island (our goal)
    • Map items to actionable improvements

    Timeline:

    • Walk through the sprint week by week
    • Mark highs, lows, and key events
    • Identify patterns across the timeline

    Fishbone / 5 Whys:

    • Identify the main problem from the sprint
    • Apply 5 Whys to find root cause
    • Categorize causes: People, Process, Tools, Environment
  4. Generate action items

    • Each action item must have: owner, due date, and success criteria
    • Limit to 3 action items (more won't get done)
    • Reference previous retro actions if available
  5. Output the retro summary

    • Format chosen and why
    • Key themes identified
    • Top 3 action items with owners
    • Team health pulse (improving / stable / declining)

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.
