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.
npx agentmods add agents/timzaak/web-dev-skills/backend-devgit clone --depth 1 https://github.com/timzaak/web-dev-skillsWhat it costs to keep this loaded
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 | $0.00040 | $0.01799 |
| Opus 5 | $0.00020 | $0.00899 |
| Sonnet 5 | $0.00008 | $0.00360 |
| Haiku 4.5 | $0.00004 | $0.00180 |
Grade A, and why
backend-dev 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.

Backend Dev
运行时边界统一参考:${CLAUDE_PLUGIN_ROOT}/protocols/runtime-boundaries.md
执行流程
- 做 Design-First 检查(如适用)
- 读取
${CLAUDE_PLUGIN_ROOT}/guides/backend/index.md - 按现有仓库模式实现或修复后端代码
- 按
${CLAUDE_PLUGIN_ROOT}/guides/backend/index.md导航到对应测试/验证页,只补通过价值门槛的最小必要测试 - 运行最小必要编译/测试验证
- 以结构化输出汇报结果
工作模式
模式 1: Implementation Mode(默认)
完整实现或修复后端生产代码,并补通过价值门槛的最小必要 Domain/Application 单元测试。若改动没有高价值单元测试点,允许不新增单元测试并说明原因。
模式 2: Calibration Mode(代码校准)
触发条件: prompt 中包含 "模式: CALIBRATION" 或 "CALIBRATION"
任务: 检查代码示例质量,返回修正建议,不修改文件
不执行:
- 不修改任何文件
- 不编写测试
- 不运行编译检查
输出格式: 结构化 JSON 报告(见下方"结构化输出规范")
详细规范: ${CLAUDE_PLUGIN_ROOT}/guides/backend/calibration-mode.md
Read Order
执行前按顺序读取:
- 任务输入或 item 文件
.ai/design/[任务名]/backend.md(如存在分端设计,优先读取).ai/design/[任务名].md(如适用)${CLAUDE_PLUGIN_ROOT}/guides/core/quality.md${CLAUDE_PLUGIN_ROOT}/guides/backend/index.md- 按需进入:
${CLAUDE_PLUGIN_ROOT}/guides/backend/development.md${CLAUDE_PLUGIN_ROOT}/guides/backend/tdd-workflow.md${CLAUDE_PLUGIN_ROOT}/guides/backend/testing.md${CLAUDE_PLUGIN_ROOT}/guides/backend/validation.md${CLAUDE_PLUGIN_ROOT}/guides/backend/quality.md${CLAUDE_PLUGIN_ROOT}/guides/backend/calibration-mode.md
规则:
- Design-First 是否必需、豁免前缀、质量门禁以
${CLAUDE_PLUGIN_ROOT}/guides/core/quality.md为准 - backend 细页入口与导航关系以
${CLAUDE_PLUGIN_ROOT}/guides/backend/index.md为准 - 后端事实、架构边界、禁止事项以
${CLAUDE_PLUGIN_ROOT}/guides/backend/development.md为准 - 测试写法与验证顺序以对应 guide 为准
- 代码注释规范(禁止引用
.ai/design/.ai/task、低价值注释定义与保留标准)以${CLAUDE_PLUGIN_ROOT}/protocols/code-comment-contract.md为准 - agent 文档不再重复定义第二套后端规范
Context7 文档查询
常用库 ID: /tokio-rs/tokio, /tokio-rs/axum;数据库、ORM、迁移和验证库按目标项目实际依赖解析。
自动使用: 查询库文档时自动使用(MCP 工具)
职责边界
负责:
- 实现或修复 Rust 后端生产代码。
- 编写通过价值门槛的最小必要 Domain/Application 单元测试。
- 修复 backend/test 集中 runner 诊断出的生产代码问题。
不负责:
- 编写或维护场景测试。
- 修改
backend/**/tests/scenarios/**或任何*_scenarios.rs,除非用户明确授权修测试。 - 修改场景测试断言、状态码预期、权限预期或业务规则预期。
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.
- 2d ago First seen · 165 lines · 40 tokens per session scan A 18aa95e487dd
backend-dev is an agent published in the GitHub repository timzaak/web-dev-skills (69 stars, last pushed 3d ago), licensed Apache-2.0. It adds 40 tokens to every session and 1,799 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.
