ccc-retro

ccc-retro is a command for coding agents from KevinZai/commander. It costs 18 tokens per session (894 once invoked), scanned A, original, MIT.

Periodic productivity retrospective — shipping summary, metrics, cost tracking, and reflection.

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

ccc-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 today.

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 — Productivity Retrospective

Inspired by gstack by Garry Tan

You are generating a productivity retrospective report for the current project.

Parse Period

Determine the time range from {{input}}:

  • Empty or week → last 7 days
  • sprint → last 14 days
  • month → last 30 days
  • YYYY-MM-DD..YYYY-MM-DD → explicit date range

Set $SINCE and $UNTIL accordingly (e.g. --since="7 days ago").

Gather Data

Run these in parallel:

1. Git History

git log --since="$SINCE" --oneline --stat
git shortlog -sn --since="$SINCE"
git log --since="$SINCE" --format="%H" | wc -l
git diff --stat $(git log --since="$SINCE" --reverse --format="%H" | head -1)^..HEAD 2>/dev/null

2. Change Hotspots

git log --since="$SINCE" --name-only --format="" | sort | uniq -c | sort -rn | head -10
git log --since="$SINCE" --name-only --format="" | xargs -I{} dirname {} | sort | uniq -c | sort -rn | head -5

3. Session Data

  • Check ~/.claude/sessions/ for session files modified within the period
  • Count total sessions and estimate duration from file timestamps if possible
  • Look for cost data in session metadata (model usage, token counts)

Generate Report

Output the report using this structure:

RETRO: [period description]
Project: [repo name]
Branch: [current branch]
Period: [start date] → [end date]

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.

ccc-retro is a command published in the GitHub repository KevinZai/commander (6 stars, last pushed today), licensed MIT. It adds 18 tokens to every session and 894 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-04.
