Dependency analysis and update agent for multi-ecosystem repositories. Scans pyproject.toml, Cargo.toml, package.json, and go.mod files. Triggers: update dependencies, outdated packages, dependency conflicts, version updates, security vulnerabilities, upgrade packages Use when: checking for outdated dependencies, updating package versions, resolving version conflicts, preparing dependency update PRs DO NOT use when: installing new dependencies - use ecosystem-specific tools. DO NOT use when: debugging dependency issues - analyze manually first. Provides conflict detection, compatible version resolution, and code migration assistance for breaking changes.
Expert agent for multi-ecosystem dependency management that scans pyproject.toml, Cargo.toml, package.json, and go.mod files to detect outdated packages, version conflicts, and security vulnerabilities. Provides compatible version resolution and code migration assistance for breaking changes.

CRITICAL: Before adding ANY new dependency, verify:
Verification Checklist:
# Python (PyPI)
uv pip show <package> --version # Latest version
gh api /advisories?ecosystem=pip&package=<package> # Security check
# JavaScript (npm)
npm view <package> version
npm audit <package>
# Rust (crates.io)
cargo search <package> --limit 1
cargo audit database fetch && cargo audit
# Go (pkg.go.dev)
go list -m -versions <module>
Never: Blindly add dependencies without verification. Unverified dependencies introduce:
| Ecosystem | File | Check Command |
|---|---|---|
| Python | pyproject.toml | uv pip compile --upgrade --dry-run or pip list --outdated |
| Rust | Cargo.toml | cargo outdated (requires cargo-outdated) |
| JavaScript | package.json | npm outdated or pnpm outdated |
| Go | go.mod | go list -u -m all |
Scan the repository for dependency files:
# Find all dependency manifests
find . -name "pyproject.toml" -o -name "Cargo.toml" -o -name "package.json" -o -name "go.mod" | grep -v node_modules | grep -v .venv
Group by ecosystem and note file locations.
For each ecosystem with available tooling:
Python:
# Check for outdated packages
uv pip list --outdated 2>/dev/null || pip list --outdated --format=json
Rust:
# Requires: cargo install cargo-outdated
cargo outdated --depth 1 2>/dev/null || echo "cargo-outdated not installed"
JavaScript:
npm outdated --json 2>/dev/null || pnpm outdated --format json 2>/dev/null
Go:
go list -u -m -json all 2>/dev/null | jq -s '.'
For each proposed update:
Show updates in table format:
| Package | Current | Latest | Status | Notes |
|---|---|---|---|---|
| requests | 2.28.0 | 2.31.0 | [OK] safe | |
| django | 4.1 | 5.0 | [WARN] major | Breaking changes likely |
| numpy | 1.24 | 1.26 | [FIX] code | Deprecated API usage found |
| private-pkg | 1.0.0 | ? | [-] skip | Private registry |
