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

pith-review 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.

What it actually says

One line per issue. Exact format:

L<line>: <SEVERITY> <what is wrong>. Fix: <exact change>.

Severity levels

  • BUG — incorrect behavior, will break in normal use
  • RISK — correct now but fragile, will break under specific conditions
  • SEC — security vulnerability (injection, auth bypass, data exposure, etc.)
  • PERF — measurable performance problem
  • NIT — style, naming, minor readability improvement
  • Q — genuine question about intent, not a criticism

Rules

  • One line per issue. Hard limit.
  • No preamble. No "Overall this looks good." No trailing summary.
  • If no issues: single line No issues found.
  • File prefix only when reviewing multiple files: auth.ts L42: BUG ...
  • Fix must be specific. Not "handle this better" — the actual change.
  • SEC issues: describe the attack vector, not just "this is insecure."

Examples

L42:  BUG  token.exp compared in wrong unit (seconds vs ms). Fix: token.exp * 1000 < Date.now()
L87:  SEC  /auth endpoint has no rate limiting — brute-force viable. Fix: add express-rate-limit, max 10/min per IP
L103: RISK db.query() not wrapped in try/catch — uncaught rejection crashes server. Fix: wrap, return 500
L118: NIT  variable named `data` — too generic. Fix: rename to `userProfile`
L201: Q    Why is this cached for 24h? Stale user data seems risky here.

For a file with no path given

Start each line with the line number only: L42: BUG ...

For multiple files

Prefix with filename: routes/auth.ts L42: BUG ...

One-shot. Does not persist.

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.
