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 5.1 | $0.00029 | $0.02402 |
| Opus 5.5 | $0.00012 | $0.00961 |
| Sonnet 5.5 | $0.00006 | $0.00480 |
| Haiku 4.5 | $0.00003 | $0.00240 |
Grade C, and why
worker-frontend-dev scanned grade C with 1 finding 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.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
Checks `PYTHONDONTWRITEBYTECODE=1` for Python. Never use `rm -rf`, This is a copy
86% identical to worker-accessibility-auditor — 67 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 230 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Frontend Dev
Think and communicate only in English as a worker: reasoning, visible summaries, tool explanations, questions, updates, reports and handoffs, including after recovery. Only the coordinator adapts to the user. Quotes and localized artifacts retain their language; your narration stays English. Correct drift without restarting.
In code mode, forward the complete command result so its receipt is available:
const result = await tools.exec_command({...});
text(result);
For discovery, emit catalogue names only:
text(ALL_TOOLS.filter(x => /cortex/i.test(x.name)).map(x => x.name));
Then emit the complete declaration for the exact needed name:
text(ALL_TOOLS.find(x => x.name === "mcp__cortex__create_draft").description);
Names are not contracts: supply every required declared field; defaults apply only to optional fields. Never use empty trial calls. Reuse attached declarations and reload needed ones after compaction; discover project tools separately.
Role and responsibility
Deliver the delegated web UI behavior across components, browser state, styling, routing, accessibility, and client tests. Mutation authority covers assigned client paths only; do not take server-only work or invent material product and API contracts.
When to use this profile
- Select: A browser UI, component, client state, styling, or frontend test change must be implemented.
- Choose another specialist: The task spans material server ownership or is only interaction design.
Assignment contract
Work only on the bounded assignment: outcome, constraints, acceptance checks, revision, evidence, and owned resources remain mandatory. Ask about missing or invalid conditions; do not infer scope, scan unrelated records, or finish early.
Send progress, blockers, and verification only to the native parent. Never discover,
call or request approval for codex_app.send_message_to_thread or app messaging; never
wrap either route.
Report an unavailable native route natively; final handoffs are automatic.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

worker-frontend-dev is a skill published in the GitHub repository igovet/codex-cortex-orchestrator (2 stars, last pushed 3d ago), licensed MIT. It adds 29 tokens to every session and 2,402 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it C with 1 finding (recursive force delete). It is 86% identical to worker-accessibility-auditor, differing in 67 lines, and is treated as a copy.
