A3.6/5.0

Scored across 2 tools

Disambiguation5/5

web_fetch retrieves content from a known URL while web_search_preview discovers URLs via query; these are complementary, non-overlapping operations with no risk of misselection.

Naming Consistency4/5

Both names use snake_case with a shared web_ prefix, which is largely consistent. The 'preview' suffix on web_search is an odd, unexplained deviation that breaks strict symmetry with web_fetch.

Tool Count3/5

Two tools is thin for a search-oriented server; the search-plus-fetch pair covers the minimal loop but leaves room for obvious additions like news/image search or batch fetch. Borderline rather than clearly well-scoped.

Completeness4/5

The search-then-fetch cycle is the core workflow and both halves are present, so no dead ends for typical use. Minor gaps exist (no news/specialized search, no bulk or crawl operations), but agents can work around them.

Available Tools

2 tools
web_fetchA
Read-only
Inspect

Purpose: Fetch and extract relevant content from specific web URLs.

Ideal Use Cases:

  • Extracting content from specific URLs you've already identified

  • Exploring URLs returned by a web search in greater depth

ParametersJSON Schema
NameRequiredDescriptionDefault
urlsYesList of URLs to extract content from. Must be valid HTTP/HTTPS URLs. Maximum 10 URLs per request.
objectiveNoNatural-language description of what information you're looking for from the URLs. Limit to 200 characters.

Output Schema

ParametersJSON Schema
NameRequiredDescription
usageNoUsage metrics for the extract request.
errorsYesExtract errors: requested URLs not in the results.
resultsYesSuccessful extract results.
warningsNoWarnings for the extract request, if any.
extract_idYesExtract request ID, e.g. `extract_cad0a6d2dec046bd95ae900527d880e7`

A3.9/5.0
Behavior3/5

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

The annotations already declare readOnlyHint=true and openWorldHint=true, so safety and variability are covered. The description adds 'extract relevant content' and objective-based filtering but gives no detail on partial-failure behavior, rate limits, or how extraction is performed, which is a modest, not severe, gap.

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 'Purpose' and 'Ideal Use Cases' headings make the content easy to parse and the purpose is front-loaded. There is minor redundancy between 'specific web URLs' and 'specific URLs you've already identified,' but no filler or irrelevant explanation.

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?

For a simple fetch tool with two parameters, full schema coverage, and an output schema, the description provides enough context about when and why to invoke it. It lacks details about failure modes or concurrency, but those are not critical given the schema and annotations already carry that burden.

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 description coverage is 100%, so the parameters are fully documented in the input schema. The description's 'relevant content' phrase implies the objective parameter influences extraction, but it does not add new meaning beyond what the schema already provides, keeping this at the baseline 3.

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 opens with a specific verb + resource: 'Fetch and extract relevant content from specific web URLs.' The two ideal use cases explicitly contrast with the sibling search tool ('URLs returned by a web search'), so an agent can immediately distinguish this from web_search_preview.

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

Usage Guidelines4/5

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

It provides clear context by listing ideal use cases: extracting from already-identified URLs or deepening exploration of search results. It implies when to use it instead of a search tool, but it does not explicitly state when not to use it or name the sibling as an alternative, so it stops short of full exclusion guidance.

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

web_search_previewB
Read-only
Inspect

Purpose: Perform web searches and return results in an LLM-friendly format and with parameters tuned for LLMs.

ParametersJSON Schema
NameRequiredDescriptionDefault
objectiveYesNatural-language description of what the web search is trying to find. Try to make the search objective atomic, looking for a specific piece of information. May include guidance about preferred sources or freshness.
search_queriesYesList of keyword search queries of 3-6 words, which may include search operators. The search queries should be related to the objective. Limited to 3 entries of 100 characters each.

Output Schema

ParametersJSON Schema
NameRequiredDescription
usageNoUsage metrics for the search request.
resultsYesA list of WebSearchResult objects, ordered by decreasing relevance.
warningsNoWarnings for the search request, if any.
search_idYesSearch ID. Example: `search_cad0a6d2dec046bd95ae900527d880e7`

TDQS

B3.2/5.0
Behavior3/5

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

Annotations already indicate read-only and open-world behavior. The description adds the LLM-friendly output format but does not mention limitations, result scope, pagination, or any other runtime behavior that the annotations do not cover.

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 purpose is stated in one concise, front-loaded sentence with no filler. Slight redundancy exists between 'LLM-friendly format' and 'parameters tuned for LLMs,' but the structure is still efficient.

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

Completeness3/5

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

The description is adequate for a simple, read-only search tool, especially with annotations and schema coverage. However, it lacks use-case boundaries, alternative tool routing, and any note on result limitations, making it incomplete for fully autonomous selection.

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 documents both parameters thoroughly, so the description adds little parameter-specific meaning. The phrase 'parameters tuned for LLMs' is vague and does not clarify individual parameter semantics.

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

Purpose4/5

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

The description clearly identifies the action ('perform web searches') and the output characteristic ('LLM-friendly format'). It is specific enough to be understood, though it does not explicitly contrast with the sibling tool web_fetch.

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

Usage Guidelines2/5

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

No guidance is given about when to choose this tool over alternatives, when not to use it, or what type of query is best suited. The sibling web_fetch is not mentioned, so an agent receives no decision-making help.

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