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.

A5/5.0
Behavior5/5

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

Describes handling of off-calendar fiscal years and sorting by primary metric, adding context beyond annotations which already mark it as read-only, idempotent, and non-destructive.

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?

Concise yet comprehensive, front-loading purpose and trigger phrases, with every sentence adding value and no fluff.

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?

Covers all aspects needed for use: input types, data sources, result ordering, and output format (paired data + citation URIs), despite no output schema.

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?

Adds significant meaning beyond the input schema by explaining the 'type' enum and 'values' array with examples, usage constraints, and what data is pulled for each type.

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?

Clearly states the tool performs side-by-side comparison of 2–5 companies or drugs in one parallel call, provides trigger phrases, and distinguishes from sequential lookups.

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 says 'ALWAYS PREFER over sequential single-pack lookups' and states it replaces 8–15 sequential lookups, guiding when to use this tool vs alternatives.

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

A4/5.0
Disambiguation3/5

Many tools are clearly distinct, but the ask_pipeworx/ask_pipeworx_beta/ask_pipeworx_grounded trio are near-identical routers (beta currently matches stable exactly), and several prediction-market tools (bet_research, polymarket_edges, polymarket_arbitrage) have overlapping use cases. Detailed descriptions mitigate but don't fully eliminate the risk of an agent picking the wrong member of a cluster.

Naming Consistency4/5

Names are consistently snake_case and mostly follow a verb_noun pattern (ask_pipeworx, compare_entities, resolve_entity, subscribe). Minor deviations like bare nouns (datasets, metadata) and bare verbs (remember, recall, forget), plus the branded ask_pipeworx variants, keep it from a perfect pattern but the style remains predictable.

Tool Count2/5

34 tools is well above the 25+ threshold and feels heavy even for a broad research platform; many are meta/utility tools (pipeworx_feedback, pipeworx_trending, suggest_questions, discover_tools) tangential to the core data-access purpose. The server name suggests a small Baton Rouge Open Data server, making the actual count a poor match for that name.

Completeness4/5

Within its actual scope, coverage is strong: universal query, grounded mode, deep research, entity/comparison profiles, entity resolution, claim validation, prediction-market edge/arbitrage/fill-risk, memory, and subscriptions all have lifecycle-appropriate tool sets. Obvious gaps are hard to find; the main issue is that the set is over-inclusive rather than incomplete.
