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 | $0.00072 | $0.03104 |
| Opus 5 | $0.00036 | $0.01552 |
| Sonnet 5 | $0.00014 | $0.00621 |
| Haiku 4.5 | $0.00007 | $0.00310 |
Grade A, and why
backend-development scanned grade A with 1 finding 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 6d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Backend Development · 后端实现知识包
M6.4 整改：v0.6.x 用 backend-agent subagent 黑盒派发，工时不可控、用户看不到中间步骤。 v0.7.0 改 main thread + 6-phase 范式（EXPLORE→PLAN→APPROVE→IMPLEMENT→VERIFY→SUMMARY）。 本 skill 是 main thread 实现 server/ 时的"必读知识包"，不再是 subagent。
Triggers
/build-api命令的 IMPLEMENT phase/impl命令串行执行后端阶段- 任何 main thread 写
server/**/*.{ts,js,java,py,go}文件时 - PR-E（v0.7.2）：当
.ddt/tech-stack.json::frontend.type === "server-side"时，模板渲染（如 Thymeleaf/JSP/FreeMarker/Jinja2/...）一并由 backend 项目承载，模板路径见frontend.template_engine对应惯例（Spring Boot Thymeleaf →src/main/resources/templates/；Django →<app>/templates/；FastAPI Jinja →templates/）。/build-web此场景跳过；本 skill 必须额外覆盖模板实现。
Inputs（main thread 必读清单）
docs/api-contract.yaml（唯一接口真相源）docs/data-model.md（数据层真相源）.ddt/tech-stack.json（栈选型 SSoT，禁止偏离）skills/api-contract-first/SKILL.md（契约优先原则）contexts/delivery.md（DDT 全局上下文）rules/delivery/agent-invariants.md（6 条全局不变量）rules/delivery/contract-integrity.md（契约完整性）- 当前栈对应的 TDD 范式（参考栈相关测试框架文档）
Hard Requirements（main thread 必须遵守）
- 契约 100% 匹配：每个 endpoint 的 request / response / error 必须 100% 匹配
docs/api-contract.yaml - 每个 endpoint 配集成测试：不合格不得提交（验证 happy path + 至少 1 个 edge case）
- 事务边界：数据层操作必须在
data-model.md声明的事务边界内 - migration + smoke test：跑 migration（如有 schema 变更）+ 本地 smoke test（health check + 简单 CRUD 路径）
- 日志 requestId：所有日志必须含
requestId与关键业务字段（脱敏后） - 栈刚性约束：必须使用
.ddt/tech-stack.json::backend段定义的 language / framework / build / database / orm / testing；禁止偏离 preset - SSoT 锁死：
.ddt/tech-stack.json仅可 Read，严禁 Write/Edit/MultiEdit（PreToolUse hook 会硬拦截） - validation loop：每完成一个文件立即跑 build / lint / type-check / test（按
skills/validation-loop/SKILL.md）失败立即停下决策
6-Phase 实施流程（main thread）
Phase 1: EXPLORE（理解现有代码）
如果 server/ 已有代码：
- 用
Grep/Glob/Read扫描现有结构 - 识别已有的 routing / middleware / db client / 测试套
- 找类似实现作参照（如已有 GET /tasks 实现，新增 POST /tasks 应沿用相同 pattern）
- 记录约定到
docs/build-api-exploration.md（用户可见 - 去黑盒）
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.
- 6d ago First seen · 223 lines · 72 tokens per session scan A b90ed3f60045
backend-development is a skill published in the GitHub repository dhslegen/digital-delivery-team (1 stars, last pushed 3mo ago), licensed MIT. It adds 72 tokens to every session and 3,104 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
