"Every dependency is a bet: you're betting that someone you've never met will maintain code you've never read for as long as you need it. How much do you actually know about those bets?"

What It Does

npm audit tells you about known vulnerabilities. npm outdated tells you about version drift. Neither tells you the things that actually matter:

Is the maintainer still actively working on this?
When was the last meaningful commit (not just a CI config tweak)?
How many of this package's 14,000 lines do you actually use?
If this package disappears tomorrow, how hard is the replacement?
Does this package pull in 47 transitive dependencies for one utility function?
Is this package's bus factor literally 1?

Dependency Autopsy performs a full health examination of every dependency in your tree and produces a risk-adjusted report.

The Autopsy Report Card

Each dependency receives a health score across seven vital signs:

Vital 1: Pulse (Activity)

Is this project alive?

Signal	Healthy	Warning	Critical
Last meaningful commit	\x3C 3 months	3-12 months	> 12 months
Open issue response time	\x3C 1 week	1-4 weeks	> 4 weeks or never
Release frequency	Regular	Slowing	Stopped
CI status	Passing	Flaky	Failing or absent
Open PRs with no review	\x3C 5	5-20	> 20

"Last meaningful commit" means a commit that changes source code.
Dependency bumps, CI tweaks, and README updates don't count.
A project can look active while being effectively abandoned.

Vital 2: Bus Factor (Maintainer Health)

How many people would need to disappear for this project to die?

Signal	Healthy	Warning	Critical
Unique committers (last year)	> 5	2-5	1
Has org ownership (not personal)	Yes	-	No (personal repo)
Has multiple npm/PyPI publishers	Yes	-	No (single publisher)
Corporate backing	Yes	Informal	None
Succession plan visible	Yes	Unclear	No

Vital 3: Bloat Factor (Weight)

How much of this package do you actually use?

ANALYSIS:
├── Total package size: 2.4 MB
├── Exports used by your code: 3 of 147 (2%)
├── Tree-shakeable: No
├── Transitive dependencies: 23
├── Transitive dependencies YOU also use directly: 2
│   └── (the other 21 exist solely because of this package)
├── Estimated bundle impact: +340 KB
└── Could be replaced with: ~30 lines of code

VERDICT: You imported an aircraft carrier to cross a creek.

Vital 4: Replacement Difficulty

If this dependency vanished today, how hard is the swap?

Difficulty	Description	Example
Trivial	Drop-in alternative exists, or you can inline the code	`left-pad` → 1 line of code
Easy	Alternative exists with minor API differences	`moment` → `date-fns` (well-documented migration)
Moderate	Alternatives exist but require meaningful refactoring	`Express` → `Fastify` (different middleware model)
Hard	Few alternatives, deeply integrated	`React` → `Vue` (rewrite)
Critical	No alternative, deeply embedded, you're locked in	`Terraform` → ? (vendor lock-in)

Vital 5: Version Health

Is your version current, and is upgrading safe?

ANALYSIS:
├── Your version: 3.2.1
├── Latest stable: 5.1.0
├── Versions behind: 2 major, 0 minor
├── Breaking changes between yours and latest: 14
├── Deprecated APIs you use: 3 (removed in v4+)
├── Security patches you're missing: 1 (medium severity)
├── Estimated upgrade effort: 8 hours
└── Risk of staying: Medium (deprecated APIs may break with Node upgrade)

Vital 6: License Health

Are you legally safe?

ANALYSIS:
├── Direct dependency license: MIT ✓
├── Transitive dependency licenses:
│   ├── MIT: 19 packages ✓
│   ├── Apache-2.0: 3 packages ✓
│   ├── ISC: 1 package ✓
│   └── GPL-3.0: 1 package ⚠ (copyleft — may require your code to be GPL)
└── License compatibility with your project: WARNING — GPL transitive dep

Vital 7: Dependency Depth

How deep does the rabbit hole go?

YOUR PACKAGE
└── dependency-a (you chose this)
    ├── dep-a-1 (you didn't choose this)
    │   ├── dep-a-1-1 (you definitely didn't choose this)
    │   │   └── dep-a-1-1-1 (nobody chose this)
    │   └── dep-a-1-2
    ├── dep-a-2
    └── dep-a-3
        └── dep-a-3-1
            └── dep-a-3-1-1
                └── dep-a-3-1-1-1 (8 levels deep. Welcome to JavaScript.)

STATS:
├── Direct dependencies you chose: 24
├── Total dependency tree: 847 packages
├── Maximum depth: 11 levels
├── Packages with 0 weekly downloads: 3 (why do these exist?)
├── Packages last published > 3 years ago: 12
└── Packages with install scripts (potential risk): 2

When to Invoke

Before adding a new dependency — full autopsy before you npm install
Monthly health check on existing dependencies
When evaluating whether to upgrade or replace a library
Before a security audit or compliance review
When investigating unexpected bundle size growth
After any npm audit report (to go deeper than just CVE numbers)

Why It Matters

The average JavaScript project has 800+ transitive dependencies. The average Python project has 40+. Each one is code you didn't write, didn't review, and don't control — running with the same permissions as your code.

npm audit tells you about known vulnerabilities. Dependency Autopsy tells you about likely future problems — abandoned projects, single-maintainer risk, license landmines, and bloat. The vulnerability that hasn't been discovered yet is in the package that nobody's looking at.

Zero external dependencies. Zero API calls. Pure package manifest and registry analysis.

安全使用建议

This skill describes a valuable but data-hungry analysis. Before installing or running it: 1) Ask the skill (or its author) which files and services it will read (package.json, lockfile, node_modules, source files, Git remote) and whether it will send data externally. 2) Expect it may need read-only tokens (e.g., a GitHub token limited to public_repo or repo:status) to check commits, PRs, and CI; do NOT hand over broad tokens or personal credentials. 3) Prefer running the analysis locally: provide a copy of package.json and lockfile or run the skill inside a sandboxed environment rather than giving networked access to your repo. 4) If you must provide credentials, use least-privilege, short-lived tokens and monitor their use. 5) If the skill will perform source-code analysis to determine 'exports used', ensure you understand whether the agent will upload source code to any external endpoint; if so, do not proceed without explicit guarantees. Because the SKILL.md does not declare the data/credential needs, treat the skill as potentially over-permissive until the author documents required inputs and data flows.

功能分析

Type: OpenClaw Skill Name: dependency-autopsy Version: 1.0.0 The `_meta.json` contains standard metadata. The `SKILL.md` describes a legitimate and useful security tool for deep dependency analysis, focusing on supply chain health, maintainer activity, and potential risks beyond typical vulnerability scanning. The documentation explicitly states 'Zero external dependencies. Zero API calls. Pure package manifest and registry analysis,' which, if true in the accompanying code (not provided), would indicate a secure design. There are no prompt injection attempts, malicious instructions, or indicators of harmful behavior in the provided files.

能力评估

⚠ Purpose & Capability

The skill claims to perform deep analysis (commit history, CI status, export usage, tree-shakeability, license scanning, transitive dependency analysis). Performing those checks normally requires access to the project's package.json/lockfile and source code and/or access to remote APIs (GitHub/GitLab, npm/PyPI) via tokens. The skill declares no required config paths, binaries, or environment credentials, which is inconsistent with the capabilities it describes.

⚠ Instruction Scope

The SKILL.md is a detailed diagnostic specification but is high-level and does not explicitly constrain where the agent should obtain data. To produce the promised metrics the agent would need to read local files (package.json, package-lock/yarn.lock, source files) and/or call remote services (repo hosting, npm registry, CI). The absence of explicit instructions about data sources or limits gives the agent broad discretion to request or access repository data or external APIs.

✓ Install Mechanism

This is an instruction-only skill with no install spec and no code files, so there is no installation-time code to fetch or execute. That minimizes disk persistence and installation-time risk.

⚠ Credentials

The analysis described would commonly require read access to: repository metadata (commit history, PRs, CI status) which often needs a GITHUB/GITLAB token, package registry metadata (npm/PyPI), and local files (package.json, lockfiles, and source). The skill declares no required env vars or config paths, so required credentials/paths are not made explicit — this is disproportionate and obscures what secrets or file access the agent will need.

✓ Persistence & Privilege

The skill does not request permanent presence (always: false) and does not declare any self-modifying or cross-skill configuration behavior. Autonomous invocation is allowed by default but is not by itself a new privilege here.
