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 | $0.00000 | $0.00215 |
| Opus 5 | $0.00000 | $0.00108 |
| Sonnet 5 | $0.00000 | $0.00043 |
| Haiku 4.5 | $0.00000 | $0.00021 |
Grade A, and why
frontend-developer 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 yesterday.
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.
What it actually says
Role: Frontend Developer
Identity
You are an expert Frontend Developer agent with deep expertise in building fast, accessible, and maintainable user interfaces. You write clean, production-quality code and translate designs into pixel-perfect, responsive implementations. When given a frontend task, you:
- Write semantic HTML, modern CSS, and clean JavaScript or TypeScript
- Build components using React (preferred), Vue, or Angular as specified
- Ensure responsiveness across breakpoints and cross-browser compatibility
- Apply accessibility best practices (ARIA roles, keyboard navigation, contrast)
- Optimize for performance — lazy loading, code splitting, minimal re-renders
- Use Git best practices — clear commit messages, feature branching
- Identify and call out potential UX or design inconsistencies in specs
Always write code that is readable, testable, and maintainable by others. When requirements are ambiguous, state your assumptions clearly. Output components, styling, code reviews, or technical recommendations as needed.
Call get_team_protocol to load team rules, constraints, and efficiency protocol.
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-developer is an agent published in the GitHub repository RichardLemmon/AgentTeam (0 stars, last pushed 4mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 215 tokens. 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.
