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 1mo 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 — Zforge Workflow Retrospective

Evaluate how well zforge's workflow scaffolding served a feature. Output feeds plugin improvement, not project documentation.

Arguments

  • $1: Feature name (snake_case or will be converted)

Pre-flight

  1. Convert feature name to snake_case.
  2. Read docs/{feature_name}/session_log.md. If not found or empty (no entries), stop: "No session history to evaluate. Run /retro at the end of a working session." Also read docs/{feature_name}/decision_review.md §B if it exists — process notes written live during the run are the primary input, and they beat reconstructing the run from its artifacts afterwards.
  3. Check current session context. If this is a fresh session with no substantial conversation about the feature (no prior tool calls touching feature files, no implementation discussion), stop: "Run /retro at the end of a working session, not in a fresh one. The retro needs session context to evaluate zforge's performance."
  4. mkdir -p docs/{feature_name}/.zforge-retro

Run the retro

Invoke the zforge:retro skill. The skill owns the scope boundary, NOT-DO rules, data sources, scoring rubric, finding quality gate, and output format — this command does not duplicate them.

Apply the skill to feature $1 and write its output to docs/{feature_name}/.zforge-retro/{session_id}.md.

Report

Present a brief summary to the user:

  • Overall score
  • Any findings worth acting on
  • If findings suggest plugin changes, mention they can be contributed as PRs to the zforge repo

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.
