retro

retro is a command for Claude Code from SarutobiSasuke8/agentops-template. It costs 12 tokens per session (225 once invoked), scanned A, original, MIT.

A command for reviewing a completed coding session and reporting what worked, what caused friction, and what should be documented for future agents.

In plain words
What is it for?
Use it after finishing a task to inspect the changes, capture useful conventions for `AGENTS.md`, and identify unresolved items.
Why use it?
It turns lessons from the session into concrete project rules, open questions, or follow-up work.

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.

What it actually says

Run a lightweight end-of-session retrospective on the work done in this conversation.

Steps:

  1. Check git diff HEAD and git status to see what actually changed.
  2. Review the conversation for decisions made, problems hit, and anything that felt awkward or slow.

Report in this format:

## What worked
- <approach, tool, or habit that helped>

## What slowed us down
- <friction point — unclear spec, repeated correction, missing context, etc.>

## AGENTS.md candidates
- <convention, rule, or preference worth codifying so future sessions don't repeat the same mistake or rediscover the same approach>

## Open questions
- <anything unresolved that should land in TODO.md or ROADMAP.md>

After the report, ask: "Want me to add any AGENTS.md candidates or open questions to the right file?"

Keep the retro honest and specific. Do not pad it. If the session was smooth, say so briefly and note only genuine candidates.

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.
