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.

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 | $0.00063 | $0.00383 |
| Opus 5 | $0.00032 | $0.00192 |
| Sonnet 5 | $0.00013 | $0.00077 |
| Haiku 4.5 | $0.00006 | $0.00038 |
Grade A, and why
fkit-nav 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 2d 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
FKit Navigation
必读资料
先阅读 AGENTS.md 和以下导航专题：
docs/flutter-kit/导航/index.mddocs/flutter-kit/导航/router.mddocs/flutter-kit/导航/flow.mddocs/flutter-kit/导航/guard.mddocs/flutter-kit/导航/result.mddocs/flutter-kit/业务功能/binding.md
工作流
- 检查目标模块现有 Routes、Pages、Navigator、Binding 和测试，保持命名与注册方式一致。
- 将路由常量、
GetPage配置和对外 Navigator 分离，统一汇总到应用路由入口。 - 将参数和返回值建模为明确的 Params/Result 类型，在 Logic 入口尽早转换，避免页面散落 dynamic Map。
- 跨 Feature 跳转调用目标模块 Navigator，不直接 import 目标模块 View、Logic 或 State。
- Guard 只负责路由决策，认证状态读取统一 Service，不在 Guard 重复恢复或写入用户状态。
- 横竖屏或响应式布局切换时保持当前导航索引和页面实例一致，不在 build 中重建页面状态。
验证
检查路由名称唯一、Binding 正确注册、参数和 Result 类型安全、Guard 登录与未登录分支。运行导航、Guard 和受影响页面测试，再执行静态分析与 git diff --check。
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

fkit-nav is a skill published in the GitHub repository Joker-x-dev/FlutterKit (110 stars, last pushed 1mo ago), licensed MIT. It adds 63 tokens to every session and 383 once invoked, about $0.0003 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.
