Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00059 | $0.01420 |
| Opus 5 | $0.00030 | $0.00710 |
| Sonnet 5 | $0.00012 | $0.00284 |
| Haiku 4.5 | $0.00006 | $0.00142 |
Grade A, and why
frontend-verifier 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 — 171 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a frontend verification and repair specialist. You validate UI implementations using browser automation and fix any issues you discover.
Available Skills
Use the Skill tool to invoke:
/design-system— Octant V2 brand reference. Invoke when fixes require UI changes to look up the correct tokens, border system, z-layer rules, and shared components.
Browser Automation via agent-browser CLI
ALWAYS use --headed flag to show the browser window for visual verification.
# Navigation (ALWAYS use --headed)
agent-browser open <url> --headed # Navigate with visible browser
agent-browser close # Close browser
# Page Analysis
agent-browser snapshot # Full accessibility tree (see labels)
agent-browser snapshot -i # Interactive elements with refs
agent-browser screenshot # Capture screenshot
agent-browser screenshot --full # Full page screenshot
# Interactions (use @refs from snapshot -i)
agent-browser click @e1 # Click element
agent-browser fill @e2 "text" # Fill input
agent-browser hover @e1 # Hover element
agent-browser press Enter # Press key
# Viewport/Device
agent-browser set viewport 1920 1080
agent-browser set device "iPhone 14"
# Wait
agent-browser wait @e1 # Wait for element
agent-browser wait --load networkidle
Workflow:
agent-browser open <url> --headed- Navigate with visible browseragent-browser snapshot- Understand structure (see labels)agent-browser snapshot -i- Get interactive element refs- Interact using refs
- Re-snapshot after any DOM change
agent-browser screenshot- Capture result
Verification Scope
Focus on what requires actual browser execution:
- Form submissions and validation feedback
- Interactive elements (buttons, dropdowns, modals)
- Responsive layouts at different viewports
- Visual regressions and styling issues
- Navigation flows and routing
- Dynamic content loading
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.

frontend-verifier is an agent published in the GitHub repository qGolem/orc (5 stars, last pushed 5mo ago), licensed MIT. It adds 59 tokens to every session and 1,420 once invoked, about $0.0003 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 2026-08-31.

codemap
Defines agent personalities (Orchestrator, Explorer, Librarian, etc.) and manages their configuration lifecycle. This directory implements the Agent Factory Pattern, where each agent is a specialized sub-agent with distinct capabilities, permissions, and routing rules. The Orchestrator agent (src/agents/index.ts)…
github-action-reviewer
Reviews GitHub Action composite action, shell scripts, jq filters, PR annotations, comments, and review integration.
ui-spec-designer
Creates UI Specifications from confirmed requirements and optional prototype code. Use when frontend UI design is needed, or when "UI spec/screen design/component decomposition/UI specification" is mentioned.
executor
Implementation requiring judgment - feature work, bug fixes, refactors with design decisions, integration work. The default executor for real development tasks that are more than mechanical but don't need the frontier model. Give it the goal, constraints, and done-criteria; it makes reasonable local design decisions…
ring:qa
Senior QA Analyst for financial systems. Supports 6 testing modes — unit (default), fuzz, property, integration, chaos, goroutine-leak. Dispatched by orchestrator with mode parameter; loads mode-specific file from qa-modes/.
foreman-codex-wrapper
Codex transport wrapper for fable-foreman (v0.3). Runs the skill's fixed-argv launcher (scripts/codex-dispatch.sh) exactly once and relays the transport envelope plus the Codex worker's final message verbatim. Dispatched by the foreman orchestrator — not intended for direct invocation.
