retro is a skill for Claude Code from mr-daedalium/ostack-saas. It costs 72 tokens per session (11,662 once invoked), scanned A, original, MIT.

A weekly engineering retrospective, meaning a review of what a software team did and learned during the week. It examines commit history, work patterns, code quality, contributors, and changes over time.

In plain words
What is it for?
Use it to prepare weekly reviews of repository activity, team contributions, work patterns, and code quality. It can identify achievements as well as areas for growth.
Why use it?
It gives a regular view of what was shipped, how work was shared, and where engineering practices could improve. Persistent history makes changes visible across multiple retrospectives.

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 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.

How it starts

The opening of the file, as written. The whole thing — 998 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Preamble (run first)

_UPD=$(~/.claude/skills/ostack/bin/ostack-update-check 2>/dev/null || .claude/skills/ostack/bin/ostack-update-check 2>/dev/null || true)
[ -n "$_UPD" ] && echo "$_UPD" || true
mkdir -p ~/.ostack/sessions
touch ~/.ostack/sessions/"$PPID"
_SESSIONS=$(find ~/.ostack/sessions -mmin -120 -type f 2>/dev/null | wc -l | tr -d ' ')
find ~/.ostack/sessions -mmin +120 -type f -delete 2>/dev/null || true
_CONTRIB=$(~/.claude/skills/ostack/bin/ostack-config get ostack_contributor 2>/dev/null || true)
_PROACTIVE=$(~/.claude/skills/ostack/bin/ostack-config get proactive 2>/dev/null || echo "true")
_BRANCH=$(git branch --show-current 2>/dev/null || echo "unknown")
echo "BRANCH: $_BRANCH"
echo "PROACTIVE: $_PROACTIVE"
source <(~/.claude/skills/ostack/bin/ostack-repo-mode 2>/dev/null) || true
REPO_MODE=${REPO_MODE:-unknown}
echo "REPO_MODE: $REPO_MODE"

If PROACTIVE is "false", do not proactively suggest ostack skills — only invoke them when the user explicitly asks. The user opted out of proactive suggestions.

If output shows UPGRADE_AVAILABLE <old> <new>: read ~/.claude/skills/ostack/ostack-upgrade/SKILL.md and follow the "Inline upgrade flow" (auto-upgrade if configured, otherwise AskUserQuestion with 4 options, write snooze state if declined). If JUST_UPGRADED <from> <to>: tell user "Running ostack v{to} (just updated!)" and continue.

AskUserQuestion Format

ALWAYS follow this structure:

  1. Recommendation: "Do X because Y." One sentence. Position first.
  2. Options: A) ... B) ... — two options, three max if genuinely needed. When an option involves effort, show both scales: (human: ~X / CC: ~Y)

Skip AskUserQuestion entirely if there's a clear right answer — just do it and report.

Never hedge. Never pad with "great question." Never restate context the user already has. Compress ruthlessly. Trust the user to keep up.

Changes

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.
