speclite-brownfield-nodejs-backend-tech-stack-digger

speclite-brownfield-nodejs-backend-tech-stack-digger is a skill for Claude Code from flanliulf/SpecLite. It costs 139 tokens per session (1,270 once invoked), scanned A, original, MIT.

A code-based checker for finding the technologies used in existing Node.js backend projects and writing an evidence-based Markdown report. It examines package files, lockfiles, runtime settings, source entry points, and deployment files.

In plain words
What is it for?
Use it to identify Node.js runtimes, package managers, backend frameworks, databases, queues, caches, storage, authentication, API documentation, logging, metrics, and tests.
Why use it?
It removes the need to manually reconstruct a Node.js service's stack from scattered files. It distinguishes detected facts from versions or details that are not confirmed by the code.

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-nodejs-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 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.

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

Speclite Brownfield NodeJS Backend Tech Stack Digger

[Overview(技能说明)] Speclite Brownfield NodeJS Backend Tech Stack Digger 是 1-analysis 阶段的 Node.js 后端技术栈挖掘工作流。它继承 speclite-brownfield-backend-tech-stack-digger 的通用报告契约,并专门处理 npm / pnpm / Yarn / Bun、lockfile、Node runtime、TypeScript、Express、NestJS、Fastify、Koa、ORM、队列、缓存、安全认证和测试等 Node.js 生态事实。

[Core Capabilities(核心能力)] - Node 项目发现:识别 package workspace、monorepo、service package、backend entrypoint、scripts.start、Docker / Procfile 启动命令。 - 包管理与版本解析:优先读取 package-lock.jsonpnpm-lock.yamlyarn.lockbun.lockb 和 package manager 字段,解析实际依赖版本。 - 运行时识别:提取 Node.js 版本来源,包括 engines.node.nvmrc.node-version、Volta、Docker image、CI setup。 - 框架识别:识别 Express、NestJS、Fastify、Koa、Hapi、Apollo Server、Next.js API route 等后端框架与入口。 - 数据与中间件分析:识别 Prisma、TypeORM、Sequelize、Mongoose、Knex、Drizzle、Redis client、BullMQ、Kafka、RabbitMQ、对象存储和 HTTP client。 - 安全与工程能力分类:识别 Passport、JWT / jose、OAuth/OIDC、validation、logging、metrics、OpenAPI、Jest / Vitest / Supertest 等事实。 - 证据化 Markdown 输出:按 assets/nodejs-tech-stack-report-template.md 生成编号清单、证据摘要、未确认项和核验命令。

[Workflow(执行流程)] 本 Skill 使用 Node.js 专属顺序分析工作流。详细包管理器矩阵、框架探测和版本解析规则见 references/nodejs-tech-stack-workflow.md

1. 解析用户输入,确认 `{project-root}`、`{output-dir}` 和 `{report-name}`。若 `{output-dir}` 缺失,必须先询问。
2. 读取通用报告契约:输出必须兼容 `speclite-brownfield-backend-tech-stack-digger` 的章节结构和证据原则。
3. 扫描 Node.js 构建入口:`package.json`、workspace config、lockfile、runtime version file、Dockerfile、CI pipeline 和 service package。
4. 可执行解析优先:根据包管理器运行 `npm ls`、`pnpm list`、`yarn list` 或 `bun pm ls`;失败时记录原因并退回 lockfile / manifest 静态解析。
5. 读取 runtime config 与源码入口,补充框架、server、database、Redis、MQ、scheduler、storage、auth、API docs、observability 和 test facts。
6. 合并事实并标注来源。`package.json` 的 semver range 不等于实际安装版本;外部服务端版本必须来自 deploy evidence。
7. 写入 `{output-dir}/{report-name}`,默认 `nodejs-backend-tech-stack.md`;最终回复给出路径、关键版本和未确认项。

[Notes(注意事项)] - 本 Skill 只分析 Node.js 后端技术栈;Java / Spring Boot、Python、Go、.NET 等生态应使用各自专属 Skill 或通用后端契约。 - lockfile 是依赖实际版本的最高优先级来源;package.json 中的 ^~、range、workspace protocol 只能作为声明事实。 - Node.js runtime 版本不能由依赖版本推断,必须来自 engines、runtime file、Docker image、Volta、CI 或用户提供证据。 - Next.js 只有在存在 API route、route handler、server action 或 custom server 证据时才写为后端框架。 - Redis Server、PostgreSQL Server、Kafka Broker、S3 / MinIO Server 等外部服务端版本不能由 Node client 版本反推。 - 生成报告必须包含 Generated By(生成来源) 标注:speclite-brownfield-nodejs-backend-tech-stack-digger

[Generation Metadata(生成信息)] 本 Skill 由 skills-creator 从通用后端技术栈报告契约中拆分 Node.js 生态规则生成。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

6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
