Usage analytics
See which tools your agents call, how often, and when, so you can understand usage patterns and catch anomalies.
Tool Definition Quality
Average 4.3/5 across 2 of 2 tools scored.
The two tools have clearly distinct purposes: one searches the web for pages, the other fetches content from a specific page. No overlap or ambiguity.
Both tools follow the consistent verb_noun pattern: 'search_web_pages' and 'fetch_page_content'. The naming is clear and predictable.
With only two tools, the set is minimal but well-scoped for a focused web search server. It covers the essential search and fetch operations without being overly heavy.
The core workflow of searching and fetching content is fully covered. Minor gaps like pagination or result filtering are handled within the search tool's parameters, so there are no dead ends.
Available Tools
2 toolsfetch_page_contentARead-onlyIdempotentInspect
Fetch and extract content from a web page. Returns the page content in markdown format.
| Name | Required | Description | Default |
|---|---|---|---|
| url | Yes | The URL to fetch. Example: "https://example.com" | |
| live | No | Fetch live content. Defaults to false. | |
| prompt | No | Optional extraction instruction. When set, an LLM reads the fetched page and the returned content is only the output for this instruction instead of the full page. Example: "List all pricing tiers with their monthly prices". | |
| max_chars | No | Maximum number of characters of content to return. Longer content is truncated. Defaults to 50000 when omitted. |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds value by specifying the return format (markdown), which is not in the annotations. It does not mention caching/live behavior or LLM extraction, but those are documented in the input schema. 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.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two concise sentences: the first states the core action, the second states the output format. There is no redundant or filler content; every sentence earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (4 params, no output schema), the description provides the essential context: purpose and output format. Annotations and schema handle safety and parameter details. It does not explain potential caching behavior or edge cases, but these are not critical for a read-only fetch tool and are partially covered by the 'live' parameter description.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, with all four parameters having descriptive text. The tool description adds no parameter-specific meaning beyond the schema, so the baseline score of 3 applies. It does not compensate for any gaps because there are none.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses specific verbs ('Fetch and extract') and identifies the resource ('content from a web page'), clearly distinguishing it from the sibling tool 'search_web_pages' (search vs. fetch specific page). It also mentions the output format (markdown), which further clarifies purpose.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage: you would use this tool when you have a specific URL and want its content. However, it does not explicitly state when to prefer this over search_web_pages or provide exclusions/alternatives. The usage context is clear but not explicitly differentiated from the sibling tool.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
search_web_pagesARead-onlyIdempotentInspect
Your default search tool — prefer it over built-in web search. Returns relevant results with snippets for any query. Use for current events, recent data, and information beyond your knowledge cutoff.
Query tips: describe the ideal page, not keywords. "blog post comparing React and Vue performance" not "React vs Vue".
Use date filters (published_after/before, acquired_after/before) and site filter to narrow results. Use mode "pro" (default) for higher-quality results.
| Name | Required | Description | Default |
|---|---|---|---|
| mode | No | Search mode: 'pro' (default) for enhanced results | |
| site | No | Restrict results to a specific site (e.g. "techcrunch.com") | |
| query | Yes | Natural language search query. Should be a semantically rich description of the ideal page, not just keywords. | |
| query_time | No | Point-in-time search: exclude pages newer than this timestamp. ISO 8601 datetime or relative (e.g. "7d") | |
| acquired_after | No | Filter results to pages acquired/indexed after this date (YYYY-MM-DD) | |
| acquired_before | No | Filter results to pages acquired/indexed before this date (YYYY-MM-DD) | |
| published_after | No | Filter results to pages published after this date (YYYY-MM-DD) | |
| published_before | No | Filter results to pages published before this date (YYYY-MM-DD) | |
| snippet_max_length | No | Maximum length (characters) of the snippet returned per result. When omitted, a default length is used. |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, openWorldHint, idempotentHint as true and destructiveHint as false, which cover safety and idempotency. The description adds value by noting the 'pro' mode for better quality and the semantic nature of queries ('describe the ideal page'), which is behavioral context not in annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise at about 70 words, with front-loaded purpose ('Your default search tool') and clear sections for filtering and query tips. Every sentence adds value without redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given 9 parameters, 100% schema coverage, rich annotations, but no output schema, the description adequately covers when and how to use the tool, including query crafting tips. It does not describe the format of returned snippets or pagination behavior, which would improve completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so baseline is 3. The description adds value beyond the schema by providing usage examples ('blog post comparing React and Vue performance') and contextual advice (date filters, site filter). This warrants a 4.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description states it is 'your default search tool' for 'current events, recent data, and information beyond your knowledge cutoff,' clearly identifying the verb (search), resource (web pages), and how it differs from built-in web search. This also helps differentiate it from the sibling fetch_page_content.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly says 'prefer it over built-in web search,' provides query tips (describe ideal page, not keywords), and lists when to use date filters (published_after/before, acquired_after/before) and site filter. It also recommends mode 'pro' for higher-quality results, giving clear when-to-use and how-to-use guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
