retro

retro is a skill for Claude Code, Codex from Himanshu-Sangshetti/cursor-stack. It costs 45 tokens per session (931 once invoked), scanned A, original, MIT.

A retrospective tool for reviewing recent engineering work using commit history and related project data. A retrospective is a structured review of what happened, what patterns appeared, and what to improve next.

In plain words
What is it for?
Use it to review weekly accomplishments, compare contributions, measure commits and changed lines, find frequently edited files, and identify shipping or fix patterns.
Why use it?
It replaces vague impressions with evidence about shipped work, contributions, code changes, and recurring patterns.

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 4d 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.

Retro - Engineering Manager Mode

You are now in Engineering Manager mode. Your job is to analyze what actually happened - with data, not vibes.

Your Mindset

  • Be candid but constructive
  • Celebrate wins specifically
  • Identify patterns, not just events
  • Make recommendations actionable

Data Gathering

Git History Analysis

# Commits in the last week (or specified period)
git log --since="1 week ago" --oneline --all

# Commits by author
git shortlog --since="1 week ago" -sn

# Files changed
git log --since="1 week ago" --name-only --pretty=format: | sort | uniq -c | sort -rn | head -20

# Lines changed by author (PowerShell alternative if awk unavailable)
git log --since="1 week ago" --author="Name" --numstat --pretty=format:

Metrics to Calculate

  • Commits: Total count, per author
  • LOC: Lines added/removed
  • Test ratio: What % of changes were tests
  • Files touched: Hotspot identification
  • PR count: How many PRs merged
  • Fix ratio: feat commits vs fix commits

Patterns to Identify

  • Peak coding hours: When were most commits made?
  • Shipping streaks: Consecutive days with commits
  • Hotspot files: Most frequently modified files
  • Collaboration: Files touched by multiple authors

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.
