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

history 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 12d 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.

How it starts

The opening of the file, as written. The whole thing — 58 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/crucible:history — Review History

List past Crucible reviews and offer to show one in full. Reviews are stored at .review/reports/<review_id>.md in the project root.

Steps

  1. List reports. Find every file under .review/reports/ matching the pattern *.md. If none exist, print:

    No past reviews found. Run /crucible to create one.
    

    and exit.

  2. Parse metadata from each report. For each file, extract:

    • review_id — from the filename (strip .md).
    • final_score — from the line beginning with **Score:** (or fall back to Score: if formatting differs).
    • final_verdict — from the line beginning with **Verdict:**.
    • scope_description — from the H1 line # Crucible Review — <description>.
    • completed_at — from the metadata line _Review ID: ... · Generated: <timestamp>_.

    If parsing fails on any field, fall back to ? for that field.

  3. Sort reports newest-first by completed_at if available, else by filename (which encodes the timestamp prefix).

  4. Print a table. Use fixed-width columns. Truncate long descriptions to 40 chars with .

    #   Review ID                          Score  Verdict                Scope
    ─────────────────────────────────────────────────────────────────────────────────
    1   2026-05-10-1430-auth-refactor      7.1    conditional_approval   auth module rewrite
    2   2026-05-09-1620-api-rewrite        8.4    approved               /api/v2 endpoints
    ...
    
  5. Prompt for selection.

    Show full report for which # (or `n` to exit)?
    
    • If the user enters a number that maps to a row, print the full contents of that report file.
    • If the user enters n, no, exit, quit, or empty, exit silently.
    • If the input is invalid, print Not a valid selection. and exit.
  6. For partial reports. Files matching *-PARTIAL.md (incomplete runs) appear in the listing with a ⚠️ prefix in the Verdict column to make it clear they don't represent a complete pipeline run.

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.
