## What it does

The skill inspects one manifest you point it at and explains every finding in plain language. It looks for Python standard-library names published as packages, backports that should not be installed on supported Python versions, dependencies with no usable version constraint, repeated entries, and exact pins that disagree. For `package.json` the stdlib and backport checks do not apply, but duplicates and unpinned values still get caught.

It runs offline. The `scripts/dep_doctor.py` script reads only the selected file, and Python 3.11+ is the requirement. The optional `--online` flag sends package names and exact pinned versions to `pypi.org` to catch yanked releases, and it asks for permission first. Without that flag nothing touches the network.

Fixes are offered, never applied silently. You get the report, then a focused edit proposal, then a wait for approval. This is a local tool for your own project, not a CI gate and not a vulnerability audit: for CVE coverage use `pip-audit` or `npm audit`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Shubhamsaboo/awesome-llm-apps --skill dependency-doctor -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/dependency-doctor/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/dependency-doctor/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Shubhamsaboo/awesome-llm-apps --skill dependency-doctor -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/dependency-doctor/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Shubhamsaboo/awesome-llm-apps --skill dependency-doctor -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/dependency-doctor/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Shubhamsaboo/awesome-llm-apps dependency-doctor
```

2. **Manually: put the files in place**
- File: `.github/skills/dependency-doctor/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Shubhamsaboo/awesome-llm-apps --skill dependency-doctor -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Shubhamsaboo/awesome-llm-apps --path agent_skills/dependency-doctor
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/dependency-doctor/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Shubhamsaboo/awesome-llm-apps --skill dependency-doctor -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/Shubhamsaboo/awesome-llm-apps/tree/HEAD/agent_skills/dependency-doctor/SKILL.md

## When to use it
- catch a package that shadows a Python standard-library module
- drop a backport that a supported Python version does not need
- pin a dependency that ships without a version constraint
- merge repeated entries into one line
- resolve conflicting exact pins before picking a version

## Example prompts
- Check `requirements.txt` for dependency problems
- Look at `pyproject.toml` and tell me what is wrong
- Are there duplicate or unpinned entries in `package.json`?

  Checks requirements.txt, pyproject.toml, and package.json dependency manifests
  for surface-level direct-dependency footguns: standard-library shadowing pins,
  abandoned backports, unpinned dependencies, and obvious intra-manifest
  conflicts, plus opt-in PyPI yanked releases. Use when the user asks to check a
  manifest for dependency problems, asks why dependencies won't install or
  whether anything is wrong with their dependencies, wants a dependency autopsy,
  or suspects dependency manifest rot. Runs offline by default as a local tool
  for the user's own project, not repository CI.

# Dependency Doctor

Inspect one dependency manifest on the user's machine for direct, surface-level
footguns. Explain each finding in plain language, then offer a small,
reviewable fix. This does not diagnose a failed pip or uv resolution.

This is a local developer tool for a project the user chooses. It is not a
repository-wide lint rule, a CI gate, or a proposal to enforce dependency
policy across unrelated apps.

## When to use

- The user asks to check, audit, diagnose, or autopsy a dependency manifest
- The user wants to rule out direct-manifest issues before deeper install debugging
- The user suspects stale pins, backports, duplicate entries, or dependency rot
- The user asks whether anything looks wrong with their dependencies

## When not to use

- Installing the current dependencies without diagnosing them
- Upgrading every package or adding a new package
- A full vulnerability audit. Use `pip-audit`, `npm audit`, or the project's
  approved security scanner for CVE coverage
- Creating a repo-wide CI check. This skill is user-invoked and local

## Choose the manifest

Use the path the user names. If no path is given and several manifests exist,
ask which one to inspect. Do not sweep the repository or edit anything merely
because the skill was triggered.

Supported inputs:

- `requirements.txt`
- `pyproject.toml` using PEP 621 or common Poetry dependency tables
- `package.json` dependency sections

## Run the offline diagnosis

From this skill directory:

```bash
python3 scripts/dep_doctor.py /path/to/requirements.txt --json
```

The default path is fully offline. It reads only the selected manifest. The
report shape is:

```json
{
````
