Server Quality Checklist

Profile completionA complete profile improves this server's visibility in search results.

Latest release: v2.2.0
Disambiguation5/5
Every tool targets a distinct aspect of AllTrails: trail details, photos, reviews, weather, GPX, search, user lists, activity feed, completed trails, profile, location resolution, and diagnostics. No two tools have overlapping purposes, making selection unambiguous.
Naming Consistency5/5
All tools follow a consistent `alltrails_<verb>_<object>` pattern using snake_case, with verbs like get, list, resolve, search. The only outlier is `alltrails_healthcheck`, which still uses the prefix and conveys its diagnostic role clearly, maintaining overall consistency.
Tool Count5/5
With 13 tools, the set is well-scoped for the AllTrails domain. It covers trail exploration, user data, search, and diagnostics without feeling bloated or sparse. Each tool serves a clear purpose and contributes to a coherent interface.
Completeness4/5
The tool set thoroughly covers read-only operations for AllTrails, including trail details, photos, reviews, weather, GPX export, user lists, activity feed, and completed trails. Gaps include lack of write/create operations (e.g., saving trails, posting reviews) and possible missing features like trail conditions or directions, but these are reasonable omissions for a read-only server.
Average 4.3/5 across 13 of 13 tools scored. Lowest: 3.7/5.

How is the quality score calculated?

The overall quality score combines two components: Tool Definition Quality (70%) and Server Coherence (30%).

Tool Definition Quality measures how well each tool describes itself to AI agents. Every tool is scored 1–5 across six dimensions: Purpose Clarity (25%), Usage Guidelines (20%), Behavioral Transparency (20%), Parameter Semantics (15%), Conciseness & Structure (10%), and Contextual Completeness (10%). The server-level definition quality score is calculated as 60% mean TDQS + 40% minimum TDQS, so a single poorly described tool pulls the score down.

Server Coherence evaluates how well the tools work together as a set, scoring four dimensions equally: Disambiguation (can agents tell tools apart?), Naming Consistency, Tool Count Appropriateness, and Completeness (are there gaps in the tool surface?).

Tiers are derived from the overall score: A (≥3.5), B (≥3.0), C (≥2.0), D (≥1.0), F (<1.0). B and above is considered passing.

Tool Scores

Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, so the description adds minimal behavioral context. It mentions 'weather overview' but does not clarify any caching, freshness, or error handling behavior. Annotations carry the safety burden.
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 a single sentence that front-loads the action and resource, with no extraneous words. It is optimally concise for a simple tool with one parameter.
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?
Given the lack of output schema, the description is vague about what the 'weather overview' includes (e.g., temperature, conditions, forecast period). For a data-returning tool, more detail on the response structure would improve completeness. Adequate but has gaps.
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 coverage is 100%, and the parameter description 'Numeric AllTrails trail id' is already in the schema. The tool description repeats this without adding new semantic meaning beyond 'weather overview' context. Baseline of 3 is appropriate.
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 verb 'Get', the resource 'weather overview for an AllTrails trail', and the method 'by its numeric trail id'. It distinguishes this tool from siblings focusing on other aspects like trail details, GPX, photos, or reviews.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for fetching weather for a specific trail using its ID, but it does not provide explicit guidance on when to use this tool versus alternatives like alltrails_get_trail (which may include weather) or alltrails_get_trail_gpx. No when-not or alternative mentions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Beyond the readOnlyHint annotation, the description adds behavioral detail: the compact=true parameter returns a specific projection with listed fields, and explains that the url serves the actual image. No contradictions 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?
Two focused sentences, no filler. Front-loaded with core purpose, then details on the optional parameter. Every statement earns its place.
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?
No output schema, so description compensates with compact output details. However, fails to describe the full output (when compact=false), pagination, or error handling. Adequate for a simple read tool but could be more complete.
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% but the description enhances meaning for the 'compact' parameter by listing the exact fields returned and clarifying the url role. This adds value beyond the schema's simple 'slim projection' text.
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 retrieves photos for a trail by numeric ID, using specific verb 'Get' and resource 'photos for an AllTrails trail'. Distinguishes from sibling tools like alltrails_get_trail (which gets trail info) and alltrails_get_trail_reviews.
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 explicit guidance on when to use this tool over siblings. Does not mention alternatives or when to avoid using it. Users must infer from the name and context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description adds context beyond the readOnlyHint annotation by stating the default behavior (signed-in user) and targeting public profiles. It does not disclose other behavioral traits like pagination, ordering, or whether private custom lists are included, but the annotation already covers the read-only nature.
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 a single sentence that efficiently conveys the action, resource, default behavior, and optional parameter. No wasted words.
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?
Given the absence of an output schema, the description does not mention the return structure (e.g., list of list names, IDs, or how favorites vs custom lists are returned). For a simple tool, this is a minor gap.
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% for the single optional parameter. The description adds minor clarification (defaults to signed-in user, targets public profiles) but does not significantly enhance understanding beyond the schema.
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 action 'List', the resource 'an AllTrails user's saved lists', and specifies subtypes 'favorites, custom lists'. It distinguishes from sibling tools like alltrails_list_completed_trails by focusing on saved lists.
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?
The description provides clear context for when to use the tool (listing saved lists) and explains the optional userId parameter for targeting specific profiles. It does not explicitly mention when not to use it or alternatives, but the context of siblings offers some guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations declare readOnlyHint=true, and description adds context about using offline-detail route geometry and returning raw GPX XML, without contradicting 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?
Two sentences, concise and front-loaded with the key action and output format, no redundant information.
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 export tool with one parameter, description covers purpose, output format, and use case adequately. No output schema, but return type is stated.
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 has 100% coverage with one parameter 'trailId' described as 'Numeric AllTrails trail id'. Description does not add further parameter details beyond schema, so 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?
Description clearly states the tool exports a trail's route as GPX 1.1 with per-point elevation, distinguishing it from sibling tools like alltrails_get_trail which likely return trail metadata.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Implies usage for saving GPX files or importing into navigation apps, but does not explicitly state when to use this versus alternatives or when not to use it.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint: true. Description adds context about default signed-in user and public profile requirement for userId. No contradictions.
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?
Two front-loaded sentences with zero waste. Essential information is presented efficiently.
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?
No output schema, and description omits return format or behavior for invalid userId. Adequate but not fully complete for a list tool.
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 covers 100% of the single parameter with adequate description. The tool description merely echoes the schema, adding no extra value beyond what the schema already provides.
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 verb 'List' and resource 'completed trails' with scope (signed-in user or specific public profile). Distinguishes from sibling tools like alltrails_get_activity_feed.
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?
Specifies when to use (list completed trails) and how to target a user via optional userId. Lacks explicit when-not or alternatives, but context is clear.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description adds behavioral context beyond the readOnlyHint annotation by explaining the compact parameter's effect on the output structure. It does not mention other behaviors like pagination or rate limits, but the annotation already covers safety.
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 two sentences: first states the purpose, second gives a specific usage tip. No unnecessary words, and the key information is front-loaded.
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 absence of an output schema, the description explains the compact output but does not detail the full response when compact=false. It covers the essential parameters and purpose, but could be more complete with default response fields.
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?
With 100% schema description coverage, the baseline is 3. The description adds some meaning for the compact parameter by repeating its structure, but it does not provide additional semantic value beyond what the schema already states for the other parameters.
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 verb 'Get' and the resource 'user reviews for an AllTrails trail', and identifies the key parameter 'numeric trail id'. This distinguishes the tool from siblings like alltrails_get_trail_photos or alltrails_get_trail_gpx.
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?
The description provides a usage tip about setting compact=true, indicating when to use that option. However, it does not explicitly state when not to use this tool or compare it to alternatives beyond the implied distinction from sibling tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate readOnlyHint=true; description adds detail about return fields and the impact of the 'compact' and 'detail' parameters, which is valuable beyond annotations. No contradictions.
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?
Two sentences: first defines purpose and returns, second recommends compact usage. No unnecessary words, front-loaded with key info.
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?
Covers return fields, detail levels, and compact option. No output schema exists, but description provides sufficient overview. Lacks error handling or authentication notes, but that's acceptable for a read-only tool.
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%, but description adds practical context: recommends compact for slim projection, explains detail levels (medium default, offline includes geometry). Adds meaning 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 explicitly states 'Get details for a single AllTrails trail by its numeric trail id' and lists the returned fields. It clearly distinguishes from sibling tools that list or search trails.
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?
Provides guidance on when to use compact=true ('recommended unless you need the full record or geometry'). Does not explicitly compare to other tools but implies this is for single-trail lookup.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Adds behavioral detail beyond readOnlyHint annotation: defaults to signed-in user, can target public profiles, feed argument determines directory vs items, pagination via cursor. No contradictions.
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?
Two sentences, front-loaded with main action, no wasted words. Every sentence adds value.
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 5 parameters, no output schema, and only readOnlyHint annotation, description fully explains all relevant behavior: directory vs items, defaults, pagination, and compact mode.
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 covers 100% of parameters; description adds semantics: feed omission meaning, compact slim projections, cursor for pagination, and default userId behavior.
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?
Description clearly states it gets an activity feed (recorded hikes and posts), distinguishes from sibling tools that focus on profiles, trails, etc. Provides specific verb+resource with contextual details.
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?
Explains use of feed argument to get items versus omitting to get directory, and compact option for slim projections. No explicit when-not-to-use, but context is clear given sibling names.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Beyond the readOnlyHint annotation, the description adds the exact API endpoint and authentication requirement, which provides useful behavioral context. It does not detail any side effects or output format, but given the simplicity, it is adequate.
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 extremely concise with two sentences: the first states the action and resource, and the second adds authentication. No superfluous information.
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 the tool has no parameters and no output schema, the description provides all necessary context: what it does, the underlying API, and a prerequisite. It is fully sufficient for an agent to decide when and how to invoke it.
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?
There are no parameters, and the schema coverage is 100%. The description does not need to add parameter info, but it does mention the endpoint, which aids understanding. A score of 4 is appropriate for a parameterless tool with sufficient context.
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 it gets the signed-in user profile using a specific verb ('Get') and resource ('user profile'). It distinguishes from sibling tools like alltrails_get_activity_feed and alltrails_get_trail, which are about different resources.
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?
The description includes a prerequisite ('Requires a signed-in session'), which guides when the tool can be used. It does not explicitly list alternative tools or when not to use it, but the context is clear and no sibling tool serves the same purpose.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already declare readOnlyHint=true, so the description does not need to restate safety. It adds value by disclosing that the returned id is an Algolia search id and is not the id used by trail-listing tools, which is important behavioral context. It also lists the fields returned. There is 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 a single, well-structured paragraph that front-loads the core purpose. It contains no superfluous information and the important note about the id is placed at the end, making it easy to scan.
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 that there is no output schema, the description does a good job listing the returned fields (kind, coordinates, URL slug, disambiguation label) and mentions the id's nature. It could be slightly improved by explicitly stating that the result is a list of location records, but overall it is complete enough for a tool with three parameters and clear constraints.
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 description coverage is 100% (all three parameters have descriptions). The description adds extra value by providing example queries ('portland oregon', 'zion') and clarifying the purpose of the query parameter. It also explains the default behavior for kinds and limit implicitly. This goes beyond the schema alone.
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 resolves a place name to AllTrails location records, listing the types (country/state/city/area/poi) and the returned fields (kind, coordinates, URL slug, disambiguation label). It also distinguishes itself from the sibling alltrails_search by noting the returned id is not for trail-listing tools and directing users to alltrails_search for that purpose.
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 guidance on when to use this tool, such as pinning down ambiguous place names like 'Oregon' or obtaining coordinates/slugs. It also includes a crucial note about the returned id not being suitable for trail-listing tools and instructs users to feed the resolved name into alltrails_search for finding trails, effectively indicating both when to use and when not to use this tool.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Beyond the readOnlyHint annotation, the description discloses critical behaviors: exact endpoint, relevance, limit honoring, result mixing, deprecated lat/lng ignored, implicit geo bias, fallback to legacy explore, and compact mode behavior. No contradictions.
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 dense with information and every sentence adds value. It is well-structured but could be slightly more concise. Still, 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?
Given the tool's complexity (search with fallback, deprecated params, mixing types, no output schema), the description covers all necessary aspects: behavior modes, parameter caveats, and output characteristics (compact, client-side cap).
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%, so baseline 3. The description adds significant value beyond schema: explains lat/lng are ignored, recommends compact, explains types narrowing only with query, and confirms limit is honored.
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 'Search AllTrails by name' with a specific verb and resource. It explains the endpoint and relevance, and distinguishes from sibling tools by noting result mixing and fallback behavior.
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?
The description provides when to use with or without query, suggests narrowing with types, recommends compact=true, and notes backward compatibility of lat/lng. It does not explicitly contrast with siblings but implies usage for free-text search.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description significantly adds behavioral context beyond the annotations (readOnlyHint, openWorldHint, idempotentHint). It details the specific URL hit, the diagnostics returned (role, port, version, RTT, hint), and states 'Read-only, no auth required', reinforcing the annotations without contradiction.
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 two sentences: the first packs all functional details efficiently, the second provides clear usage guidance. No wasted words.
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?
The description fully covers purpose, usage, behavior, and expected output (diagnostics). Despite no output schema, it explicitly names the returned fields and hint logic, making it self-contained.
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?
There are zero parameters, so schema coverage is trivially 100%. The description does not need to explain parameters. Baseline score of 4 is appropriate.
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 it performs a round-trip test through the fetchproxy bridge using a specific small URL, and lists the exact diagnostics returned. This verb+resource specificity distinguishes it perfectly from sibling data-retrieval tools.
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?
Explicitly says 'Call this when a real tool fails' which is a clear usage condition. However, it does not explicitly state when not to use, though the context of sibling tools makes this evident.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Beyond the readOnlyHint annotation, the description adds that items are sparse references, that compact=true returns slim entries sorted by order, and that the list id is numeric. No contradictions 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 a single efficient paragraph. It front-loads the main purpose, then explains the nature of items and the compact option without any wasted words.
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?
With only two parameters and no output schema, the description fully covers what the tool does, the content of items, and how to proceed for full details. It references sibling tools appropriately.
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% (listId required, compact optional boolean). The description adds meaning beyond the schema by explaining that compact=true returns entries sorted by order, and that listId is numeric, which is not in the schema description.
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 gets trails saved in an AllTrails list by numeric list id, specifying that items are sparse references (trailId, order, notes) and not trail details. It distinguishes from siblings like alltrails_get_trail by noting the need for hydration.
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?
The description explains when to use the tool (with a list id from alltrails_list_user_lists or alltrails_search) and suggests using alltrails_get_trail for full details. It could be improved by explicitly stating not to use this tool if full trail details are needed.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
