Discover Tools

discover_tools
Read-onlyIdempotent

Find tools by describing the data or task. Use when you need to browse, search, look up, or discover what tools exist for: SEC filings, financials, revenue, profit, FDA drugs, adverse events, FRED economic data, Census demographics, BLS jobs/unemployment/inflation, ATTOM real estate, ClinicalTrials, USPTO patents, weather, news, crypto, stocks. Returns the top-N most relevant tools with names, descriptions, and full input schemas (with curated examples) — each result is ready to call directly, no second schema lookup needed. Call this FIRST when you have many tools available and want to see the option set (not just one answer).

A4.5/5.0
Behavior4/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false. The description adds that results include full input schemas with examples and are 'ready to call directly, no second schema lookup needed,' which is valuable behavioral context beyond 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?

The description is front-loaded with the primary purpose and progressively adds details. It is somewhat lengthy but each sentence contributes distinct value (domains, return format, usage, aliases). Could be slightly more concise but remains efficient.

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

Completeness4/5

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

Given the high schema coverage, no output schema, and sufficient behavioral context, the description is complete enough. It explains what the tool returns, how to use it, and when to call it. No critical gaps identified.

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

Parameters4/5

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

Schema coverage is 100%, and the schema already describes parameters with aliases. The description adds context by emphasizing that the query is a natural language description and provides examples (e.g., 'analyze housing market trends'), reinforcing the parameter meaning without redundancy.

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 explicitly states 'Find tools by describing the data or task' and lists specific domains like SEC filings, FDA drugs, etc. It clearly distinguishes from sibling tools by positioning itself as a discovery tool, not a specific data tool.

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?

The description provides explicit usage guidance: 'Call this FIRST when you have many tools available and want to see the option set (not just one answer).' It implies when to use (browsing/discovery) and when not (seeking a single answer), suggesting alternatives like calling specific tools directly.

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

A4.1/5.0
Disambiguation4/5

Tools cover a wide range of domains (TV, finance, betting, memory, etc.), each with detailed descriptions that help distinguish their purposes. However, some overlap exists between related tools like bet_research, polymarket_arbitrage, and polymarket_edges, though the descriptions clarify their distinct uses.

Naming Consistency4/5

Most tool names follow a consistent verb_noun pattern with underscores (e.g., get_show, list_episodes, resolve_entity). A few tools use single imperative verbs (remember, recall, forget), which is a minor deviation but still clear.

Tool Count3/5

The server has 31 tools, which is on the higher side. While each tool has a defined purpose, the scope seems too broad for a server named 'Tvmaze', as many tools are unrelated to TV (e.g., company analysis, betting, memory). A more focused set would improve coherence.

Completeness4/5

For a general-purpose data server, the tool set covers a wide range of tasks: TV show lookups, company research, betting analysis, memory management, and more. The inclusion of ask_pipeworx as a fallback for many queries compensates for missing specific tools. However, the TV-specific functionality is limited to search and schedule, missing details like cast or crew.
