Compare Entities

compare_entities
Read-onlyIdempotent

"Compare X and Y" / "X vs Y" / "X versus Y" / "which is bigger / better / larger / more profitable" / "rank these companies" / "head to head" — side-by-side comparison of 2–5 companies or drugs in ONE parallel call. ALWAYS PREFER over sequential single-pack lookups when comparing entities. type="company" pulls LATEST 10-K revenue + net income + cash + long-term debt from SEC EDGAR/XBRL (off-calendar fiscal years handled correctly — AAPL Sep, NVDA Jan, etc.). type="drug" pulls FAERS adverse-event counts, FDA approval counts, active trial counts. Results sorted by primary metric so "largest" / "most" / "biggest" reads off the top of the response. Returns paired data + pipeworx:// citation URIs per entity. Replaces 8–15 sequential lookups.

TDQS

A5/5.0
Behavior5/5

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

Annotations cover readOnly and non-destructive nature, but description adds significant behavioral context: source systems (SEC EDGAR/XBRL, FAERS), handling of off-calendar fiscal years, sorting by primary metric, paired data output, and citation URIs. 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 dense but every sentence earns its place. Front-loaded with trigger phrases, then behavior, type-specific details, and output format. No fluff or repetition.

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 effectively explains return structure (paired data + citation URIs), sorting, and covers both entity types. Includes performance benefit (replaces 8-15 lookups) and edge cases (fiscal year handling). Complete for a tool with only 2 parameters.

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

Parameters5/5

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

Schema coverage is 100%, but description enriches parameter meaning substantially: explains what data each type pulls (10-K financials vs adverse-event counts), expected value formats (tickers/CIKs vs drug names), and result sorting behavior. This goes beyond basic schema descriptions.

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 states the tool's purpose with specific verbs ('Compare', 'rank', 'head to head') and resource scope (2-5 companies or drugs). It distinguishes from sequential single-pack lookups and specifies data sources (SEC EDGAR/XBRL, FAERS).

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 states 'ALWAYS PREFER over sequential single-pack lookups when comparing entities', providing clear when-to-use guidance and an alternative. Also differentiates between type='company' and type='drug' usage.

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

A3.6/5.0
Disambiguation2/5

The server is named 'spacex' but contains a vast number of tools unrelated to SpaceX, such as polymarket arbitrage, npm package scanning, and claim validation. Users and agents would struggle to determine whether this server is for SpaceX data or general-purpose queries.

Naming Consistency2/5

The SpaceX-specific tools follow a consistent 'get_' pattern, but the majority of tools use varied naming conventions (e.g., 'ask_pipeworx', 'bet_research', 'remember', 'subscribe'). No unifying pattern across the set.

Tool Count3/5

36 tools is a moderately large count, not extreme. However, many tools are unrelated to the server's namesake, making the set feel bloated and unfocused. The count could be trimmed to improve coherence.

Completeness2/5

For the SpaceX domain, the coverage is decent (launches, rockets, crew, Starlink). But the server's purpose is unclear—there are glaring gaps in a unified vision, as the Pipeworx tools are not integrated into a coherent SpaceX theme.
