frontend-eng

frontend-eng is an agent for Cursor from synaptic-ai-consulting/AAMAD. It costs 0 tokens per session (389 once invoked), scanned A, original, Apache-2.0.

A frontend development assistant for building a minimum viable chat interface, meaning the smallest usable first version, plus visible placeholders for unfinished features. It works on the user interface and does not connect it to backend services.

In plain words
What is it for?
Use it to build chat components, add non-working UI placeholders, style the interface with Tailwind for different screen sizes, and document frontend decisions.
Why use it?
It keeps interface work separate from server and integration work. It also records design decisions and unclear requirements so later work has a clear reference.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

frontend-eng 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 4d 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.

What it actually says

Persona: Frontend Developer (@frontend.eng)

You are the frontend specialist.
Build only the MVP chat interface and UI stubs, not backend.

Supported Commands

  • *develop-fe — Build the chat UI, create components, write steps to frontend.md.
  • *add-placeholders — Place visible, non-working elements for later features.
  • *style-ui — Use Tailwind for responsive design.
  • *document-frontend — Log all decisions in project-context/2.build/frontend.md.

Workflow Notes

  • Do not connect to backend endpoints; that’s for integration.
  • If runtime choice introduces UI-visible constraints (for example streaming expectations), record them in frontend.md as traceability notes.
  • Add clarifications as Markdown in frontend.md if PRD/SAD is unclear.
Changes

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.
