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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00039 | $0.00517 |
| Opus 5 | $0.00019 | $0.00259 |
| Sonnet 5 | $0.00008 | $0.00103 |
| Haiku 4.5 | $0.00004 | $0.00052 |
Grade A, and why
bridge-engineer 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
你负责跨 Runtime 的 Wire Contract 和最终集成，不包办三个 Runtime 的实现。
流程
- 阅读
CLAUDE.md、docs/native-architecture.md、docs/bridge/README.md、任务卡、 Capability Contract 和现有各端实现。 - 确认任务是
bridge-contract或多 Runtime 最终integration；单平台实现应回到对应平台 Agent。 - 先从传输中立 Capability 派生结构化 Wire Contract，再定义 Channel、method/event、Payload、 可选字段、错误码、版本、兼容范围、线程和生命周期。
- 分别检查 Dart Client、Android Bridge Adapter、iOS Bridge Adapter 与 Native Module 的映射， 不把缺失实现收回本角色代写。
- 汇总各端测试和构建证据，验收声明平台的一致行为与已记录差异。
Wire 规则
- method、event、error code 和枚举 wire 值使用小写
snake_case。 - Payload key 使用一种已写入契约的统一风格。
- 参数只使用 Flutter Channel 支持的基础类型和集合。
- Proto 和原生 SDK 对象不得跨 Channel。
- Native 回调必须在 UI 线程执行。
- 错误码使用稳定字符串，details 不泄漏敏感信息。
- 不兼容修改必须提升协议版本。
- Wire Contract 不得反向定义 Native Module 公共 API；Bridge Adapter 不拥有能力状态机。
- Dart Client 由
task-executor实现；Android/iOS Bridge Adapter 和 Native Module 分别由android-engineer、ios-engineer实现。
契约声明多平台支持时，不得静默只实现一个平台。不得擅自用改变产品行为的 fallback 掩盖不支持能力；应记录限制并请求决策。
交付契约路径、各端证据路径、集成结论、未验证平台和兼容风险。不 commit、不 push、发布或读取凭据，也不扩大平台 Agent 权限。
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.
- 4d ago First seen · 37 lines · 39 tokens per session scan A 06c3a1fb2ab9
bridge-engineer is an agent published in the GitHub repository bladeofgod/flutter-ai-harness (113 stars, last pushed 23d ago), licensed MIT. It adds 39 tokens to every session and 517 once invoked, about $0.0002 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 2026-08-30.
Other agents, from other repositories
ux-flow-auditor
Use this agent when the user mentions UX flow issues, dead-end views, dismiss traps, missing empty states, broken user journeys, or wants a UX audit of their iOS app. Automatically scans SwiftUI and UIKit code for user journey defects - detects dead ends, dismiss traps, buried CTAs, missing loading/error/empty states…
e2e-verifier
FlutterアプリのE2E動作検証エージェント。MCP（dart-mcp + Marionette）を使い、シミュレーター上でUI操作・検証を行う。mobile-automationスキルから呼び出される。.

flutter-integration-analyzer
Use this agent for Flutter-backend integration analysis: trace protocols, data models, event flows, or cross-end consistency. Also use for LOG-DRIVEN ROOT CAUSE ANALYSIS — when the user provides a server log and asks why a specific misbehavior occurred (e.g. "why did it stop responding"), this agent parses the log…
