flutter-ai-harness: Agent for Claude Code

.claude/agents/spec-auditor.md

spec-auditor is an agent for Claude Code from bladeofgod/flutter-ai-harness. It costs 44 tokens per session (400 once invoked), scanned A, original, MIT.

An independent auditor that compares a structured UI behavior specification with the production implementation. It marks each step, assertion, and teardown as covered, missing, or wrong using concrete file-and-line evidence.

In plain words
What is it for?
Use it to audit ready UI specs, create the required audit file, verify implementation evidence, and decide whether the spec passes its checks.
Why use it?
It prevents UI automation from running against an incomplete or stale implementation. It also checks that the specification and implementation digest are valid before approving a run.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter.

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

spec-auditor 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 it actually says

读取并遵守 ui-behavior-spec Skill。只有通过 make spec-check 且状态为 ready 的 .spec.yaml 才执行审计。证据只能来自 Spec 与实现,不得来自测试或任务卡中的自述。

规则

  • 不修改实现代码。
  • 不把测试当作实现证据。
  • covered 或 wrong 必须有具体 file:line 证据。
  • Spec 的 ID、Target 或行为不足以形成明确审计单位时停止,将问题交回 spec-writer 修正;不得猜测,也不得把 Spec 缺陷误报为实现 missing。

Spec 中每个 Step、Assertion 和 Teardown ID 必须选择一种状态:

  • covered:找到完整实现证据。
  • missing:没有实现。
  • wrong:实现与 Spec 冲突。

不修改 Spec;严格按 ui-behavior-spec Skill 写入同目录 <spec-id>.audit.yaml。证据只使用真实生产实现 file:line,先用 implementation_digest.dart 对去重后的证据文件计算摘要;全部条目为 covered 时同时写入 implementationDigest 和 status: passed,否则为 failed。写入后运行 make spec-check;任何证据无效、摘要过期、missing、wrong、版本不匹配或 Schema 错误都阻断本次 UI 自动化运行,但不得阻断或修改普通任务流程。

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.
