Scan Dependency

scan_dependency
Read-onlyIdempotent

Composite "should I add this npm package to my project" check in ONE call — fans out across deps.dev (license + advisories + version history) and bundlephobia (gzipped/minified bundle size, dependency count, ESM/tree-shake support). Use whenever an agent asks "is X safe / popular / small" or "what does adding lodash cost me". Returns a summary block (is_latest, license, published_at, advisory_count, bundle_kb_min, bundle_kb_gz, dependency_count, has_esm, tree_shakeable), per-advisory detail, links, and a list of recent alternative versions. NPM ecosystem only in v1; PyPI / Maven / Cargo / Go fall under deps.dev:version directly. Partial failures degrade gracefully — bundlephobia's first measurement on a new version can take 5-30s; sources_failed will list it if it times out, the rest still returns.

A4.6/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Description adds significant behavioral context beyond annotations: fans out to multiple services, explains return structure (summary block, advisories, links, alternatives), mentions potential delay of 5-30s on bundlephobia first measurement, and graceful degradation via sources_failed. No contradiction with annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Description is comprehensive but slightly verbose. Every sentence adds value, but it could be more structured. Front-loaded with the key purpose. Minor deduction for unnecessary words like 'Composite... check'.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no output schema, the description fully explains the return value: fields in summary block, per-advisory detail, links, and alternative versions. Also covers partial failures and ecosystem limitations. Complete for the tool's complexity.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so baseline is 3. Description does not add meaning beyond what the schema provides: it repeats that package is npm name with scoped support and version defaults to latest. No extra semantics.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states the tool is a composite check for npm packages to answer 'should I add this package?' by combining deps.dev and bundlephobia data. It uses a specific verb and resource, and is distinct from sibling tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly tells when to use: when an agent asks about safety, popularity, size, or cost of an npm package. Also tells when not to use: only npm ecosystem in v1, and mentions alternatives for other ecosystems (deps.dev:version directly).

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

A3.7/5.0
Disambiguation2/5

The ask_pipeworx family (stable, beta, grounded) are nearly identical, with beta explicitly matching stable, creating clear misselection risk. The five polymarket_* tools and several research tools (deep_research, bet_research, entity_profile) also overlap in purpose despite detailed descriptions.

Naming Consistency3/5

Tool names are mostly snake_case and readable, with consistent prefixes (ask_pipeworx_, polymarket_, easypost_), but mix verb-first (validate_claim, resolve_entity) and noun-first (entity_profile, ai_visibility_check) conventions. The server name 'Easypost' does not align with the overwhelmingly Pipeworx-focused tool set.

Tool Count2/5

33 tools is a heavy count, especially with three near-duplicate ask_pipeworx variants and many meta-tools. The set is also unfocused: only two shipping tools under an 'Easypost' label while the rest are a broad data-research and prediction-market platform, making the count feel bloated for the apparent scope.

Completeness2/5

As an Easypost server, shipping coverage is severely incomplete (rates and tracking only, no label purchase, address verification, or refunds). Within the Pipeworx tools, the cited pipeworx:// URIs have no direct fetch-by-URI tool, leaving a notable dead end for agents trying to retrieve full records.
