Comprehensive dependency management expertise covering TypeScript (npm, yarn, pnpm, bun), Rust (cargo), and Python (pip, poetry, uv). Use when working on projects requiring: (1) Dependency auditing and listing, (2) Checking for outdated packages, (3) Security vulnerability scanning, (4) Finding release notes and changelogs, (5) Preparing upgrade reports with breaking change analysis, (6) Inspecting transient dependencies in lock files, (7) Installing or uninstalling packages, (8) Clearing package caches, (9) Monorepo workspace dependency management, or (10) Cross-ecosystem dependency health checks.

Comprehensive guidance for managing dependencies across TypeScript, Rust, and Python ecosystems.
Audits dependencies for vulnerabilities, outdated versions, transitive issues, and licenses in Node.js, Python, PHP, Ruby, Go, and Rust projects using npm audit, pip-audit, and equivalents.
Reviews project dependencies for outdated versions, CVEs, end-of-life status in Node/npm, Python/pip, Rust/Cargo projects, and proposes safe updates with risk evaluation and breaking change checks.
Scans npm, pip, Cargo, Go, Ruby projects for outdated packages, runs CVE audits, summarizes changelogs with Gemini, opens PRs per risk group (patch/minor/major).

Comprehensive guidance for managing dependencies across TypeScript, Rust, and Python ecosystems.
Commands over inference. Always run the actual package manager command to get information rather than reading manifest or lock files and inferring state. The package manager is the authority on what is installed, what is outdated, and what is vulnerable.
npm ls tells you what is installed — package.json tells you what should be installed. These can differ.cargo tree shows the resolved dependency graph — Cargo.toml shows declared dependencies.pip list shows what is in the environment — requirements.txt shows what was requested.Reading manifest files is useful for understanding project structure and intent, but command output is the source of truth for current state.
If you are dispatched with a specific ecosystem (e.g., "typescript"), skip detection and load the relevant reference directly.
If you need to detect the ecosystem, scan the project root for these files:
| Files Found | Ecosystem | Package Manager |
|---|---|---|
package.json + package-lock.json | TypeScript/JS | npm |
package.json + yarn.lock | TypeScript/JS | yarn |
package.json + pnpm-lock.yaml | TypeScript/JS | pnpm |
package.json + bun.lockb | TypeScript/JS | bun |
package.json (no lock file) | TypeScript/JS | npm (default, warn about missing lock file) |
Cargo.toml | Rust | cargo |
pyproject.toml with [tool.poetry] section | Python | poetry |
pyproject.toml with [tool.uv] section or uv.lock present | Python | uv |
pyproject.toml (no poetry/uv markers) | Python | pip |
requirements.txt (no pyproject.toml) | Python | pip |
Check for workspace configurations:
| Indicator | Type |
|---|---|
package.json with "workspaces" field | npm/yarn workspace |
pnpm-workspace.yaml | pnpm workspace |
Cargo.toml with [workspace] section | cargo workspace |
When a monorepo is detected:
Once you know the ecosystem, load the appropriate reference file for specific commands:
| Task | What It Does | Reference |
|---|---|---|
| Locate dependencies | List all direct and dev dependencies from manifest files | typescript.md, rust.md, python.md |
| Check for updates | Compare installed versions against latest available | Per-ecosystem reference |
| Security audit | Scan for known vulnerabilities (CVEs, advisories) | Per-ecosystem reference |
| Find release notes | Locate changelogs or release notes for a package version | Per-ecosystem reference |
| Upgrade report | Identify breaking changes, deprecated APIs, migration guides | Per-ecosystem reference |
| Transient dependencies | Inspect lock files and dependency trees for indirect deps | Per-ecosystem reference |
| List installed | Show what is actually installed (not just declared) | Per-ecosystem reference |
| Install / uninstall | Add or remove packages with correct flags | Per-ecosystem reference |
| Clear caches | Clean package manager caches and stores | Per-ecosystem reference |
