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

scrub 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 7d 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.

The opening of the file, as written. The whole thing — 172 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Scrub

Core Rules

Local loop/review scrubs are read-only advisory scans. Cosmetic lint/style findings are LOW and are not Done Criteria. Report them and explicitly ask the user before cleanup; no answer is not approval. Use -Advisory, never -Fix during the unapproved scan. See .github/AGENT-PROTOCOL.md section 4.

Do not reclassify real build, correctness, security, reliability or accessibility defects as cosmetic lint. Independent default/production, CI and commit gates remain unchanged; report their failures rather than claiming they passed.

When to Use / Not Use

Use after generation, refactor, or a large patch; before a PR or review handoff; after approval but before merge; periodically on machine-heavy directories. No prerequisites -- it runs standalone through the Frontier CLI.

When NOT to Use

  • During active debugging -- focus on correctness first
  • On generated code that is intentionally machine-owned (build output, OpenAPI clients)
  • On vendored third-party files
  • As a substitute for code review -- scrub catches presentation, review catches behavior

What Counts As Slop

Category Examples Proposed cleanup after approval
Comment rot // This function handles the logic for X, // Helper to do thing, naked // TODO Delete
Restating the obvious // Increment counter above counter++ Delete
Dead code Commented-out code blocks of 4+ code-like lines Delete
AI filler phrasing Phrases like "Note that", "To", or "Next" when they add no meaning Rewrite or delete
Duplicate logic Repeated normalized code blocks within one file Consolidate manually (flag only)
Over-abstraction Single-use interface, factory wrapping one constructor, getter-only class Inline manually (flag only)
Generic UI defaults bg-gradient-to-r from-purple-500 to-blue-500, placeholder lorem ipsum Replace with brand palette (flag only)
Stale boilerplate Created by ... on ..., Last modified by ... Delete
Empty try/catch catch (e) { /* ignore */ } with no logging Flag for review

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.
