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

/retro

Args

  • phase-{N} (e.g., phase-1)

Process

  1. Gather data from Linear (closed tasks in cycle N) + git log (commits during cycle) + learnings written during cycle
  2. Synthesize:
    • What shipped (count + highlights)
    • Cycle time avg
    • Decisions made (with PR links)
    • Scope changes from original phases.yaml
    • Learnings (count + key ones)
    • What to do differently next phase
  3. Write to docs/retros/phase-{N}.md using templates/retro.template.md

Output

Retro file path + 5-bullet summary printed to terminal.

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.
