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 5.1 | $0.00092 | $0.03484 |
| Opus 5 | $0.00046 | $0.01742 |
| Sonnet 5 | $0.00018 | $0.00697 |
| Haiku 4.5 | $0.00009 | $0.00348 |
Grade A, and why
flet-development 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 10d 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.
How it starts
The opening of the file, as written. The whole thing — 414 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Flet 1.0+ 开发指南
Provide expert guidance for developing Flet applications with version 1.0+ (>= 0.82.0), which introduces breaking changes from Flet 0.x and requires updated APIs, patterns, and best practices.
⚠️ CRITICAL: Before You Start
创建新项目时，第一件事必须是：
✅ 项目创建决策树
需要创建新的 Flet 项目？
↓
【是否已有项目目录和文件？】
├─ 否 → 使用官方脚手架，运行 flet create
└─ 是 → 直接在用户已经预先准备好的目录和代码文件里开始编写代码。一般默认优先查找改动已有的main.py。
↓
【如果是flet create情况，检查生成的文件】
├─ pyproject.toml ✅
├─ src/main.py ✅
└─ src/assets/ ✅
↓
【开始在 src/main.py 中编写代码】
🚨 常见错误
| 错误行为 | 后果 | 正确做法 |
|---|---|---|
直接写代码，不运行 flet create |
缺少标准结构、依赖管理 | 第一步：flet create |
| 手动创建 pyproject.toml | 版本不兼容、配置错误 | 使用官方脚手架 |
| 在根目录直接创建 main.py | 不符合标准项目结构 | 在 src/main.py 编写 |
⚡ 快速开始命令
# 创建新项目（推荐）
flet create
# 运行项目
flet run
⚠️ 重要：flet create 会替换现有的 README.md 或 pyproject.toml（如果存在）；如果用户要指定项目名称，则原则上禁止项目名称包含大写字母和中文，因为可能会影响后续的项目打包。
When to Use
✅ Invoke this skill when:
| 触发场景 | 第一行动 | 说明 |
|---|---|---|
| 🎨 创建新的 Flet 项目 | ⚡ 立即运行 flet create |
生成标准项目结构（pyproject.toml、src/main.py 等） |
| 🔧 开发任何 Flet 功能 | ⚡ 查阅示例代码和 API 参考 | ⚠️ 必须持续查阅，不是只查一次！ |
| 🖥️ 开发桌面/Web 应用 | 加载本 skill | 获取最新 API 指导和最佳实践 |
| 🔄 从 Flet 0.x 迁移 | 查阅 Breaking Changes | 处理 79+ 个 API 变更 |
| 🐛 遇到 API 错误 | 检查 Critical API Traps | BorderRadius、Tabs、Colors、KeyboardEvent 等常见陷阱 |
| ⚙️ 异步操作 | 参考 Procedural Rules | 文件选择器、对话框、延迟 |
| 🎨 主题和样式 | 查阅 API Quick Reference | Colors、Alignment、Buttons 等 |
❌ Do NOT invoke for:
- General Python questions unrelated to Flet
- Flet 0.x compatibility questions (use migration guidance instead)
Purpose
Flet 1.0+ introduces 79+ breaking changes from Flet 0.x, with all deprecated APIs removed. This skill provides:
- Accurate API usage - Verified through Python inspect, not documentation alone
- Critical trap avoidance - Common mistakes with BorderRadius, Tabs, Colors, Alignment
- Migration guidance - Step-by-step migration from Flet 0.x
- Performance patterns - Auto-update mechanism, batch operations

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.

flet-development is a skill published in the GitHub repository HnBigVolibear/awesome-flet-development-skill (24 stars, last pushed 5mo ago), licensed MIT. It adds 92 tokens to every session and 3,484 once invoked, about $0.0005 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.
