speclite-brownfield-backend-tech-stack-digger

speclite-brownfield-backend-tech-stack-digger is a skill for Claude Code from flanliulf/SpecLite. It costs 135 tokens per session (1,253 once invoked), scanned A, original, MIT.

A code-based checker that identifies the technologies used in an existing backend project and writes a Markdown report. It uses files such as dependency locks, configuration, deployment settings, migrations, and source code as evidence.

In plain words
What is it for?
Use it to map monoliths, multi-module projects, monorepos, and backend services, then record languages, frameworks, databases, caches, messaging, security, monitoring, testing, and their evidence.
Why use it?
It replaces a manual, guess-based inventory with a documented view of the backend stack. Unknown versions and facts that code cannot prove are marked for follow-up.

Token cost

What 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.

Security

Grade A, and why

speclite-brownfield-backend-tech-stack-digger 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 7d 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

[Overview(技能说明)] Speclite Brownfield Backend Tech Stack Digger 是 1-analysis 阶段的通用后端技术栈报告契约。它不绑定 Java、Node.js、Python 或任何单一生态,只规定如何基于代码事实抽取技术栈、标注证据和写入用户指定输出目录。

[Core Capabilities(核心能力)] - 输出目录参数化:从用户请求中解析 {output-dir} 和可选 {report-name},默认生成 {output-dir}/backend-tech-stack.md。 - 仓库与模块发现:识别 monolith、multi-module、monorepo、service directory 和 backend entrypoint,定位后端边界与构建入口。 - 代码事实提取:读取构建声明、依赖锁定文件、运行配置、部署配置、数据库迁移、源码入口和框架标识;历史文档只作为候选线索。 - 版本解析优先级:优先使用锁文件、resolved dependency graph、运行镜像和工具链声明;直接依赖声明次之;无法确认时标记 unknown。 - 技术栈归类:按语言、运行时、包管理/构建工具、Web/API 框架、Web server、数据库、MQ、缓存、数据访问、调度、文件存储、安全认证、观测和测试等类别输出。 - 证据链接与不确定性标注:每个关键版本必须带来源说明;服务端外部版本无法由代码证明时明确写为需要运维确认。 - Markdown 报告生成:按 assets/tech-stack-report-template.md 生成面向交付的清单式文档,并追加证据摘要。

[Workflow(执行流程)] 本 Skill 使用顺序分析工作流。详细证据矩阵、版本解析规则和输出模板约束见 references/tech-stack-digger-workflow.md

1. 解析用户输入,确认 `{project-root}`、`{output-dir}` 和 `{report-name}`。若缺少 `{output-dir}`,必须先询问;不得写入默认项目根目录。
2. 创建或确认 `{output-dir}`,默认报告文件名为 `backend-tech-stack.md`。若目标文件已存在,先读取并说明将覆盖、追加或生成带时间戳文件;用户未授权时不覆盖。
3. 扫描仓库结构、语言生态和构建入口。若识别到已有专属生态 Skill 可提供更精确解析,优先建议或路由到对应专属 Skill;未命中时按通用证据规则分析。
4. 读取运行配置和源码证据,补充数据库、Redis、MQ、调度、文件存储、安全认证、服务发现、网关、监控和测试工具事实。
5. 按证据优先级合并事实。冲突时保留全部候选、标注来源和优先级,不自行猜测生产运行版本。
6. 使用 `assets/tech-stack-report-template.md` 输出 Markdown:先给出用户要求的编号清单,再给出证据摘要、未确认项和核验命令。
7. 写入 `{output-dir}/{report-name}` 后,检查文件存在、标题、编号清单和 evidence anchors;最终回复只给出路径、核心发现和无法确认项。

[Notes(注意事项)] - 本 Skill 是分析与文档生成工具,不修改业务源码、构建配置或运行配置。 - 代码事实优先于 README、历史方案、聊天记录和人工记忆;文档事实必须能被构建文件、配置文件或源码交叉验证后才能写成确定结论。 - 数据库 Server、消息中间件 Server、缓存 Server、对象存储 Server 等外部服务端版本通常不能仅由应用仓库证明;只能在配置、Compose、Helm、运维脚本或锁定镜像中找到证据时写确定版本。 - 依赖版本来自生态专属解析机制时,必须写明来源,例如 lockfile、resolved dependency graph、constraints file、runtime image 或 internal framework baseline。 - 生成报告必须包含 Generated By(生成来源) 标注:speclite-brownfield-backend-tech-stack-digger。 - 如用户要求更新 _speclite/tech-stack.md,必须先确认这是目标输出文件;否则只写入用户指定目录。

[Generation Metadata(生成信息)] 本 Skill 由 skills-creator 根据既有后端项目技术栈分析流程提取生成。后续修改必须同步更新 SKILL.md、SKILL.en.md、CHANGELOG.md,并同步 forge/ 与 SpecLite assets 源目录。

What ships with it

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.
