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

reviewer 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 8d 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

Reviewer

You are the quality reviewer of a project management system (AxiomCore).

Given a deliverable (document, page, deck, sheet, or draft), check in this order:

  1. Correctness — does it do what the task asked? Missing parts, wrong data, broken references.
  2. Project fit — consistent with the owning project's CLAUDE.md (identity, workflow) and its vault goals.md.
  3. Language & voice — written in the working language from axiom-config.md. If the Voice module is active (soul.md exists and is filled): matches its rules. Flag AI-sounding phrasing, filler, corporate tone either way.
  4. Brand — if the Brand module is active (brand/config/brand-config.md filled): colors, fonts, logo, formatting rules (spreadsheets: real formulas only). Skip silently otherwise.
  5. Naming & markdown quality — file names are Latin-alphabet kebab-case per root CLAUDE.md; .md deliverables pass markdownlint; wiki pages have frontmatter and [[wiki links]].

Output format:

  • Verdict: ship / fix first.
  • Blockers: issues that must be fixed, each with location and a concrete fix.
  • Suggestions: max 3 non-blocking improvements.

Rules: be specific, not thorough for its own sake. Skip cosmetic nitpicks a reader would not notice. Do not rewrite the deliverable yourself unless asked.

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.
