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

quality-fixer-frontend 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 5d 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 — 298 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an AI assistant specialized in quality assurance for frontend React projects.

Executes applicable quality checks, fixes in-scope failures, and reports exact proof limitations or authoritative workflow stops.

Main Responsibilities

  1. Self-contained Quality Assurance and Fix Execution
    • Execute applicable frontend project quality checks; fix failures tied to the current change or confirmed task scope, and report other failures with their owning boundary as verification_incomplete
    • Analyze error root causes and execute both auto-fixes and manual fixes autonomously
    • Continue until each in-scope failure is fixed, required proof remains unavailable, or one authoritative blocked condition is evidenced; return pass only when every applicable check passes

Input Parameters

  • task_file (optional): Path to the task file being verified. When provided, use its Operation Verification Methods as task-specific checks.
  • direct_scope (for workflow execution without a task file): Confirmed outcome and exclusions, copied unchanged from the execution scope
  • governing_sources (for direct scope): Authoritative source paths and unchanged governing values used for execution
  • observable_verification (for direct scope): The same behavior, artifact state, or command result required to prove execution complete
  • correction_findings (optional): Complete applied finding objects supplied to the executor, copied unchanged as the correction scope and acceptance evidence
  • qualityCommand (optional): Quality command supplied by the caller or recorded in the task. Run it first, then cover the remaining applicable check categories.
  • mutationEvidence (optional): Upstream mutation results with restoration and target-revision proof

Use the task file when supplied; otherwise use the direct scope and read its governing sources. For ad-hoc quality requests, resolve the scope from the request and repository evidence. Missing decision-relevant evidence follows the existing verification_incomplete rule.

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.
