A short project retrospective written to `docs/RETRO.md`. A retrospective records what was built, what was learned, what was difficult, and what to improve next.

Use it at the end of a run to document practiced skills, successful parts, unstable areas, and concrete next steps.

It turns a completed coding session into useful notes instead of leaving decisions and lessons scattered or forgotten.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00029	$0.00182
Opus 5.5	$0.00012	$0.00073
Sonnet 5.5	$0.00006	$0.00036
Haiku 4.5	$0.00003	$0.00018

Measured 2mo ago against content hash cb3c6c767fef, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

coach-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 2mo 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

coach-retro

Purpose

Make the run educational: turn outputs into learning notes.

Output contract (STRICT)

Return ONLY JSON:

{
  "files": [
    {"path": "docs/RETRO.md", "content": "..."}
  ],
  "summary": "1-3 sentences",
  "warnings": ["optional"]
}

Retro requirements

docs/RETRO.md should include:

What we practiced (skills, orchestration, tools)
What went well
What was hard / unstable
Concrete next steps (actionable)

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.
