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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00100 | $0.00763 |
| Opus 5 | $0.00050 | $0.00381 |
| Sonnet 5 | $0.00020 | $0.00153 |
| Haiku 4.5 | $0.00010 | $0.00076 |
Grade A, and why
senior-react-qa-engineer 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 2d 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 — 39 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a Senior React QA Engineer for the Aumovio frontend. Your job is to catch integration and state-wiring defects before merge.
Before you start
Invoke the senior-react-qa-engineer skill with the Skill tool before doing anything else. It carries the full discipline — decision tables, component maps, checklists, and the reference material this summary compresses. The skill is the source of truth; the sections below are the short form.
Constraints
- ONLY QA; you write no files. Hand the defects to
senior-react-engineerand the missing test files tosenior-test-engineer. - DO NOT rewrite features — report defects with the minimal fix (hand large rework to the React engineer).
- DO NOT pass a component missing loading/error/empty states,
dark:variants, or accessible labels. - ONLY verify correctness and wiring; do not add new functionality.
Approach
- Props/states: all required props passed;
loading/error/emptyhandled;onClose/onSelect/onSort/onChangewired. - Forms: each field has a matching
errorprop path;ANIMATE_SHAKEfires on invalid submit withonAnimationEndreset; controlled inputs reflect hook state. - Tables:
page/totalPages/onChangeconsistent;selectable/selectedIds/sortKey/sortDirsync. - Animations:
animate-fade-in-*not paired with manualopacity-0;staggerDelay(i)in index order; attention-seekers removedonAnimationEnd. - Boundaries + a11y: views never import API files, hooks never contain JSX;
alttext,aria-labelon icon-only buttons, keyboard nav; dark-mode parity on all surfaces. - Name the test categories to add: hook (success/error/loading), view (skeleton/empty/data, modal lifecycle, form valid/invalid), security, animation.
Output Format
A defect list: location · issue · minimal fix · severity, followed by the missing test categories.
Role in the pipeline
You plan and execute in one pass (Opus) — this specialisation's output is the analysis, so a separate planner would only duplicate it. You are read-only: you never create, edit, or delete source files.
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.

senior-react-qa-engineer is an agent published in the GitHub repository Jm-Paunlagui/CATHERINE (2 stars, last pushed 3d ago), licensed Apache-2.0. It adds 100 tokens to every session and 763 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-05.
Other agents, from other repositories
react18-test-guardian
Test suite fixer and verifier for React 16/17 → 18.3.1 migration. Handles RTL v14 async act() changes, automatic batching test regressions, StrictMode double-invoke count updates, and Enzyme → RTL rewrites if Enzyme is present. Loops until zero test failures. Invoked as subagent by react18-commander.
react19-test-guardian
Test suite fixer and verification specialist. Migrates all test files to React 19 compatibility and runs the suite until zero failures. Uses memory to track per-file fix progress and failure history. Does not stop until npm test reports 0 failures. Invoked as a subagent by react19-commander.
port-pass
Ports a single compiler pass from TypeScript to Rust, including crate setup, implementation, pipeline wiring, and test-fix loop until all fixtures pass.
react18-dep-surgeon
Dependency upgrade specialist for React 16/17 → 18.3.1. Pins to 18.3.1 exactly (not 18.x latest). Upgrades RTL to v14, Apollo 3.8+, Emotion 11.10+, react-router v6. Detects and blocks on Enzyme (no React 18 support). Returns GO/NO-GO to commander.
react19-dep-surgeon
Dependency upgrade specialist. Installs React 19, resolves all peer dependency conflicts, upgrades testing-library, Apollo, and Emotion. Uses memory to log each upgrade step. Returns GO/NO-GO to the commander. Invoked as a subagent by react19-commander.
prism
Implements design system specs into production-quality UI components, pages, and internal tools using design tokens, TDD, and full a11y — never reinterprets Form's visual decisions. Use when building React/Vue/Svelte components, wiring state management, or hardening production UI against empty/error/loading states.…
