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.

A4.7/5.0
Behavior5/5

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

Annotations already indicate read-only, idempotent, non-destructive behavior. The description adds substantial behavioral context: possible 5-30s delay on first bundlephobia measurement, graceful partial-failure behavior with sources_failed, and the combined-output nature of the tool. 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.

Conciseness5/5

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

The description is compact relative to the tool's complexity; it front-loads purpose, then delivers usage, output fields, ecosystem limitations, and failure behavior without filler. Every sentence contributes actionable information.

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?

No output schema is present, but the description compensates by naming the full set of return fields, per-advisory details, links, alternative versions, and failure behavior. It fully covers the composite nature, latency, and scope, making the tool self-sufficient for an agent.

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?

The input schema already fully documents both package and version, including that version defaults to latest when omitted. The description does not add new parameter-level meaning beyond the schema, so the high-coverage baseline of 3 is appropriate.

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?

The description clearly identifies the tool as a composite npm dependency vetting check, enumerating the exact data sources (deps.dev and bundlephobia) and the question it answers (should I add this package). It distinguishes itself from direct deps.dev lookups by noting when the direct tool applies instead.

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?

Explicit usage triggers are given, such as 'is X safe / popular / small' or 'what does adding lodash cost me'. The description also provides an exclusion: non-NPM ecosystems should go to deps.dev:version directly, which is clear when-not-to-use guidance.

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

A3.8/5.0
Disambiguation2/5

Several tools occupy overlapping question-answering territory: ask_pipeworx_beta currently behaves identically to ask_pipeworx, while ask_pipeworx_grounded, deep_research, and validate_claim all route the same data catalog and differ mainly in output guarantees. The six Polymarket tools also split edge detection, arbitrage, and fill-risk in ways that are easy for an agent to conflate. Clear exceptions like the memory and subscription trios keep it from a 1.

Naming Consistency4/5

Names are uniformly lowercase snake_case and most follow a readable verb-first or domain-prefixed pattern (get_package, list_releases, scan_dependency, ask_pipeworx_*). The Polymarket family uses noun phrases after a prefix (polymarket_edges, polymarket_fill_risk) and a few names are noun-first (entity_profile, recent_changes), which is a minor inconsistency rather than chaos.

Tool Count2/5

35 tools is well beyond the comfortable 3-15 range and even above the 16-25 heavy range. The broad Pipeworx data scope justifies some expansion, but identical ask_pipeworx_beta, six overlapping Polymarket tools, and unrelated utility families (Hex.pm, AI visibility, memory, llms.txt) suggest bloat rather than deliberate scoping.

Completeness4/5

Within its main data-access purpose, the surface is unusually complete: query (ask_pipeworx), grounded verification (ask_pipeworx_grounded/validate_claim), deep research, entity resolution/profiling, comparison, change feeds, and search-within are all present, and memory/subscription subdomains have full CRUD. There are minor gaps for the package side (no docs/dependents) and the hodgepodge of domains makes a single 'complete' surface hard to define, but no workflow hits a hard dead end.
