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 | $0.00075 | $0.02415 |
| Opus 5.5 | $0.00030 | $0.00966 |
| Sonnet 5.5 | $0.00015 | $0.00483 |
| Haiku 4.5 | $0.00007 | $0.00242 |
Grade A, and why
frontend-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 1mo 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.

Frontend Development · 前端实现知识包
M6.4 整改：v0.6.x 用 frontend-agent subagent 黑盒派发。v0.7.0 改 main thread + 6-phase 范式。 本 skill 是 main thread 实现 web/ 时的"必读知识包"。
Triggers
/build-web命令的 IMPLEMENT phase（仅frontend.type === "spa"；server-side/none由 build-web Phase 1 提前 noop 退出）/impl命令串行执行前端阶段- 任何 main thread 写
web/**/*.{tsx,ts,vue,html,css}文件时 /design-brief编译 brief 与/design-execute --channel <type>派发/摄取外部设计稿时
PR-E（v0.7.2）：当
.ddt/tech-stack.json::frontend.type是server-side（Thymeleaf/JSP/FreeMarker/...）或none时，没有独立的web/工程，本 skill 不应被触发。模板由 backend 项目（如src/main/resources/templates/）承载，归/build-api+skills/backend-development处理。
Inputs（main thread 必读清单）
docs/api-contract.yaml（唯一接口真相源）docs/prd.md（UX 语义参考）.ddt/tech-stack.json（前端栈 + ai_design 选项 SSoT，禁止偏离）skills/api-contract-first/SKILL.md（契约优先原则）skills/ai-native-design/SKILL.md（AI 设计稿工作流：claude-design / figma / v0）contexts/delivery.md（DDT 全局上下文）rules/delivery/agent-invariants.md（6 条全局不变量）
Hard Requirements（main thread 必须遵守）
- 严格按契约：不得擅自发明字段、改字段名、改错误码（contract 不清写 blocker，不要猜）
- build/lint/typecheck：完成后必须跑构建 + lint + type-check + 最小 happy-path UI 测试
- 代码组织：
web/目录；组件测试放web/__tests__/ - 统一 client：所有网络调用走统一 client（自动从 OpenAPI 生成 types，如
openapi-typescript） - 栈刚性约束：必须使用
.ddt/tech-stack.json::frontend段定义的 framework / bundler / ui / state / data_fetching；禁止偏离 - AI-native UI 工作流：按
tech-stack.json::ai_design.type决定 UI 来源（claude-design / figma / v0）；接入流程统一为/design-brief→/design-execute --channel <type>→ main thread 按ai-native-design SKILL §7改写 - SSoT 锁死：
.ddt/tech-stack.json仅可 Read，严禁 Write/Edit/MultiEdit（PreToolUse hook 硬拦截） - validation loop：每完成一个组件立即跑 build / lint / type-check / 组件测试，失败立即停下
6-Phase 实施流程（main thread）
Phase 1: EXPLORE
如果 web/ 已有代码：
- 用 Grep / Glob / Read 扫描组件树 + 已有 hooks / store / api client
- 找类似页面作参照
- 落
docs/build-web-exploration.md
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.
- 1mo ago First seen · 172 lines · 75 tokens per session scan A 702f14c6e719
frontend-development is a skill published in the GitHub repository dhslegen/digital-delivery-team (1 stars, last pushed 5mo ago), licensed MIT. It adds 75 tokens to every session and 2,415 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-08-31.
