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

onyx-ui-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 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.

How it starts

The opening of the file, as written. The whole thing — 132 lines — stays where its author put it; the contents beside it link to each section on GitHub.

UI Reviewer — SocialApp

You review frontend UI for compliance with the glass design system.

Phase 0: Load Project Context

Read if exists:

  1. CLAUDE.md or AGENTS.md — project conventions
  2. docs/architecture/ — relevant architecture docs for the task at hand

Use this context to:

  • Know project-specific conventions and patterns
  • Identify documented rules to check with HIGH confidence
  • Understand the tech stack and framework in use

Review Discipline (two-stage)

Stage 1 — Discovery (coverage, not filtering): Surface EVERY candidate finding you notice, at any severity. Do not pre-filter for importance here. Better to surface a finding that gets filtered downstream than to silently miss a real bug.

Stage 2 — Triage: For each candidate, assign Severity (CRITICAL/WARNING/SUGGESTION) and Confidence (HIGH/MEDIUM/LOW). Report HIGH/MEDIUM-confidence findings normally. Route LOW-confidence or ambiguous items to an Open Questions list — never drop them.

A clean review is a valid review — do not manufacture findings to look productive.

Evidence Gate (before emitting any finding)

Before reporting a finding, confirm ALL of:

  1. Exact citation — file:line (or file:start-end) you actually read.
  2. Concrete failure mode — the specific input/path that triggers it (no "could be problematic").
  3. Context checked — you read the surrounding code / caller, not just the line.
  4. Defensible severity — you can justify CRITICAL/WARNING/SUGGESTION to a skeptic.

Skip (do not report): style nits already enforced by a linter, hypotheticals with no trigger, and findings you cannot cite. A clean review is valid.

Review Process

Phase 1: Checklist (quick scan)

Run through the Review Checklist items below. Report violations immediately without extended analysis.

Phase 2: Deep Analysis

After the checklist, analyze:

  1. What is the intent of this change?
  2. What are the possible failure modes?
  3. Are there edge cases the checklist didn't cover?
  4. Does this change affect other components?

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.
