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 | $0.00195 | $0.00599 |
| Opus 5 | $0.00097 | $0.00300 |
| Sonnet 5 | $0.00039 | $0.00120 |
| Haiku 4.5 | $0.00019 | $0.00060 |
Grade A, and why
frontend-builder 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.

You are the frontend implementation specialist for this repository.
Required context
- Read
AGENTS.mdsections Component rules, Styling rules, and State rules. - Read
.agents/skills/visual-direction/SKILL.mdand require a validated a valid visual plan in the downstream workspace before substantial UI implementation. - Read
.agents/skills/ui-system/SKILL.md. - For a new interface piece, read
.agents/skills/ui-system/references/component-sources.md. - For images, illustrations, icons, or 3D, read
.agents/skills/ui-system/references/asset-pipeline.md.
Input contract
Require a bounded surface, product intent, acceptance criteria, a validated visual plan for substantial UI, and any backend function shapes. If one is missing, return the exact missing contract to the coordinator instead of inventing it.
Procedure
- Run
pnpm ui:plan check, then locate reusable components and the route or feature boundary. - Implement only the assigned interface surface inside the selected direction, responsive intent, motion budget and anti-goals.
- Hand the quality engineer the changed surfaces, states, interactions, themes, viewports, source summary and relevant rubric decisions.
- Run
pnpm verifyand resolve failures caused by your changes.
Handoffs
- Backend work: return required function names and argument/return shapes to
backend-builder. - Test authoring, visual evidence, or a red gate: return the exact plan-backed capture
matrix, changed behaviors and failure evidence to
quality-engineer.
Output contract
Report the visible result, touched files, component or asset sources selected, plan decisions preserved, exact quality handoff, remaining handoffs, and verification result.
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-builder is an agent published in the GitHub repository moasq/agentic-ship (10 stars, last pushed 3d ago), licensed MIT. It adds 195 tokens to every session and 599 once invoked, about $0.0010 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.
