flutter-ai-harness: Skill for Claude Code

.agents/skills/execute-ui-spec/SKILL.md

execute-ui-spec is a skill for Claude Code from bladeofgod/flutter-ai-harness. It costs 26 tokens per session (214 once invoked), scanned A, original, MIT.

A procedure for auditing a ready UI specification and running the requested checks on Android or iOS. A UI specification is a written description of how an interface should be built and behave.

In plain words
What is it for?
Use it to perform a static audit and specified runtime validation for a ready UI specification on Android, iOS, or both.
Why use it?
It helps verify that an approved interface specification is followed and that the selected platform works as required. It is only used when a person explicitly assigns the work.

Skill for Claude Code

Written for Claude Code: $ARGUMENTS substitution. Also seen: installed under .agents/ (shared by several agents); mentions Codex; $skill-name invocation.

This is bladeofgod/flutter-ai-harness's own configuration. It tells Claude Code how to work on flutter-ai-harness itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything flutter-ai-harness configures →

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

execute-ui-spec 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 2mo 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 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.
