loop-frontend-implementation

loop-frontend-implementation is a skill for Claude Code, Codex from Oriolshhh/runware-image-mcp. It costs 22 tokens per session (484 once invoked), scanned A, a copy of loop-context-compression, MIT.

A structured workflow for designing and building a frontend interface, then checking it in a browser.

In plain words
What is it for?
Use it to create a frontend surface, map the existing design system, define responsive states, implement the interface, and validate it in a browser.
Why use it?
It coordinates design decisions, implementation, approval points, and independent review so the finished interface can be checked against its requirements.

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

loop-frontend-implementation 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 8d 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

Loop: frontend-implementation

Follow the ordered workflow below. Respect every human-approval gate, iteration bound, and stop condition.

name: frontend-implementation
description: Design and build a new frontend surface with browser-backed quality evidence.
max_iterations: 3
steps:
  - name: orient
    instruction: Reuse repository context; normalize the user, task, surface, constraints, content, success criteria, preview, and test setup.
  - name: system-map
    agent: design-system-specialist
    instruction: Map reusable tokens, primitives, components, themes, stories, and frontend conventions before proposing new ones.
  - name: direction
    agent: frontend-design-lead
    instruction: Produce one planning-only, brief-specific direction, complete state/responsive contract, acceptance rubric, and smallest implementation plan without recursively invoking the end-to-end /frontend-design command.
  - name: approve-material-decisions
    instruction: Wait for explicit approval only when brand, navigation, product behavior, shared design-system APIs, or dependencies materially change.
    gate: human-approval-when-required
  - name: implement
    agent: frontend-implementer
    instruction: Implement the approved direction with complete states, responsive behavior, accessibility, tests, and no unapproved dependencies.
  - name: browser-verify
    agent: visual-qa-tester
    instruction: Exercise the real UI across representative states and viewports; compare acceptance evidence and inspect console/network/runtime behavior.
  - name: specialist-review
    instruction: Run independent accessibility review and motion review when motion changed; return only verified in-scope blockers.
  - name: gates-and-decide
    instruction: Run configured gates; stop on acceptance, otherwise repeat only for an in-scope correction below max_iterations.
    gate: gates/default.yml

Apply context-discovery before broad scanning: use a supplied context capsule first; otherwise check context frontmatter freshness, read .agent/context/routing.md, load only relevant summaries, and verify critical claims against source.

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.
