Server Quality Checklist

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

Latest release: v0.3.0
Disambiguation5/5
Each tool targets a distinct GTM entity and action. Tags, triggers, variables each have their own create/get/list/update/delete, and workspace/version lifecycle tools are clearly separate.
Naming Consistency5/5
All tools follow a consistent verb_noun pattern with snake_case. Verbs like create, list, get, update, delete, publish are used uniformly across entities.
Tool Count5/5
24 tools cover the core GTM workflow without bloat: account/container/workspace listing, version management, and full CRUD for tags, triggers, variables. Each tool earns its place.
Completeness4/5
The tool set provides full lifecycle management for tags, triggers, variables, and versions. Missing account/container creation is acceptable as these are typically managed outside CI/CD.
Average 4.4/5 across 24 of 24 tools scored. Lowest: 3.3/5.

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 indicate readOnlyHint: true, so the description does not carry the full burden. However, it adds no additional behavioral traits beyond what is stated (e.g., no mention of potential costs, permissions, or data freshness). This is acceptable but minimal.
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?
Extremely concise: a single sentence for purpose followed by a parameter list. No wasted words, front-loaded effectively.
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 complexity (3 required params, read-only tool, output schema exists), the description is minimally adequate. It does not explain what 'unpublished changes' or 'merge conflicts' entail, nor error conditions. The presence of an output schema mitigates the need to describe return values, but more context would help.
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 description's Args section adds some value by explaining that account_id and container_id accept numeric or full resource path, and hints to find workspace_id via list_workspaces. This partially compensates for the 0% schema coverage, but the parameter descriptions are still minimal and mostly repeat schema info.
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 states the tool shows unpublished changes and merge conflicts in a workspace, which is a specific verb+resource. However, it does not explicitly differentiate it from sibling tools like get_live_version or get_version, though its focus on workspace status makes it unique enough.
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 on when to use this tool versus alternatives. It does not mention prerequisites, context, or exclusions, leaving the agent to infer usage solely from the purpose.
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?
Annotations already declare readOnlyHint=true, so the description does not need to restate that. However, it adds no behavioral context (e.g., pagination, defaults, or output format).
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?
Extremely concise: one-line purpose followed by parameter docs. No wasted words, front-loaded with the action.
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?
Output schema exists, so return values are covered elsewhere. The description covers core functionality and parameter format well. Missing minor details like authentication or rate limits, but sufficient for a simple read-only list tool.
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 0%, but the description fully compensates by explaining the parameter types (numeric ID or full path) with examples, adding significant meaning 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 'Lists workspaces in a container' with a specific verb and resource. It distinguishes from sibling list tools like list_tags, list_containers, etc.
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 on when to use this tool vs alternatives. No mention of prerequisites or context beyond parameter types.
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?
Annotations declare readOnlyHint=true, so the description adds no new safety information. It explains parameter format but does not disclose pagination, limits, or ordering behavior. This is adequate given the read-only nature, but lacks additional context.
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, front-loaded with the core purpose. No unnecessary words or 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?
For a simple list tool with an output schema, the description is complete. It identifies the parameter and its formats. No additional details are needed.
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 description coverage is 0%, so the description must compensate fully. It explains the account_id parameter with examples of numeric ID and full path, adding significant meaning beyond the schema's type definition.
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 'Lists all containers in a Google Tag Manager account,' specifying the verb and resource uniquely. It distinguishes from sibling tools like list_tags and list_workspaces, which target 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 Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives. There is no mention of prerequisites, when not to use it, or comparisons to siblings like list_accounts or list_workspaces.
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 annotations already declare readOnlyHint=true, and the description's 'Gets' aligns with that. Beyond annotations, the description adds the detail 'full configuration' to hint at the output scope, but does not disclose any other behavioral traits (e.g., authorization needs, rate limits). With annotations covering the safety profile, this is adequate but not enriched.
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 highly concise: a single sentence stating the purpose followed by a terse parameter list. No wasted words, and the purpose is front-loaded. Every sentence earns its place.
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 tool's complexity (4 required parameters) and the presence of an output schema, the description covers purpose, parameter meanings, and ID retrieval hints. It lacks explicit error conditions or prerequisite permissions, but the read-only nature and parameter guidance make it largely complete. The sibling set is large, and the description adequately differentiates the tool.
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?
Despite 0% schema description coverage, the description compensates thoroughly. For each parameter it clarifies acceptable types ('Numeric account ID or full resource path') and provides actionable guidance on how to obtain values ('find it via list_workspaces', 'find it via list_variables'). This goes well beyond the minimal schema, making the tool easily usable.
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 the full configuration of one variable,' specifying the verb and resource. Among sibling tools that also begin with 'get_', it uniquely targets 'variable', distinguishing it from gets for tags, triggers, versions, etc.
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 provides implicit usage guidance by listing required parameters and hints on obtaining IDs (e.g., 'find it via list_workspaces'). However, it does not explicitly state when to prefer this tool over alternative getters or exclude cases, leaving usage context somewhat implied.
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 indicate a write operation (readOnlyHint=false) and non-destructive (destructiveHint=false). The description adds transparency by explaining the draft behavior, that changes stay local until publication, and that it returns the created tag with tagId. 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 well-structured with a clear purpose statement, a behavior paragraph, and an args section. It is slightly verbose but each sentence adds value. Could be more concise, but remains effective.
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 complexity (4 params, nested objects, no schema description) and the existence of an output schema, the description covers key aspects: draft lifecycle, parameter explanations, return value, and a note about built-in triggers. Missing are potential errors or permission requirements, but overall complete.
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?
With 0% schema description coverage, the description fully compensates by explaining all four parameters. It gives specific instructions for workspace_id (find via list_workspaces) and details the tag resource body structure, including required fields and a minimal example.
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 'Creates a tag in the workspace draft,' specifying the verb, resource, and scope. It distinguishes from sibling tools like create_trigger and create_variable by emphasizing the draft lifecycle and that nothing goes live until publication.
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 provides context on when to use (creating tags in draft) but lacks explicit when-not-to-use or alternatives. It implies the tool is for initial creation, not updates, but does not mention update_tag or deletion as alternatives.
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 explains that the deletion is reversible until publication and requires confirmation, adding context beyond the destructiveHint annotation. It aligns with the annotation and provides useful behavioral details.
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 concise and front-loaded with purpose and key requirement (confirmation). It then lists parameters efficiently. Slightly more brevity could be achieved, but it is well-structured.
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 destructive tool with 5 parameters and an output schema (not shown), the description covers the key behavioral and parameter context. It doesn't explain the output, but that is covered by the output schema. The draft lifecycle and confirmation are well explained.
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?
With 0% schema description coverage, the description compensates by explaining each parameter: types (numeric or path), sources (list_workspaces, list_tags), and the special confirm parameter requirement. This adds significant meaning 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 that the tool deletes a tag from the workspace draft, using specific verbs and the resource. It distinguishes from sibling tools like create_tag, update_tag by focusing on deletion and mentioning the draft scope.
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 explicit guidance: ask user first, then call again with confirm=True. It also notes that removal is not final until publishing. It doesn't mention alternatives or when not to use, but the context is clear.
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?
Annotations already declare readOnlyHint=true; description adds that it returns 'slimmed contents' and compares to get_version, but no further behavioral context (e.g., no mention of pagination or error states).
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?
Three concise paragraphs: purpose, comparison, use case, then clear Args list. No wasted sentences.
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?
With an output schema present, the description need not detail return format. It covers purpose, parameters, and usage context fully. Could mention read-only nature explicitly, but annotations cover it.
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?
Both parameters are described beyond the schema (e.g., 'Numeric account ID or full resource path') despite 0% schema description coverage, fully compensating for the gap.
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 'Gets the container version currently published (live)', specifies return type ('metadata plus slimmed contents'), and compares to get_version, distinguishing it from sibling 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?
Provides a specific use case ('useful to see what is live before publishing a new version') and implies get_version for historical versions, but lacks explicit when-not-to-use or alternative descriptions.
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 discloses that returned contents are slimmed to avoid large outputs and that other get functions read the workspace draft. It adds meaningful context about what the tool does and does not do, though it could mention potential error cases.
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 no redundant sentences. It front-loads the main purpose, then adds necessary context and alternative guidance in a well-structured paragraph, making efficient use of space.
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 read-only nature and existence of an output schema, the description covers the key behavioral aspects: what is returned, why it's slimmed, and alternative tools. It could mention error handling for missing version or invalid IDs, but overall it's sufficiently complete.
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 0% schema description coverage, the description provides basic parameter clarification: each can be numeric ID or full resource path, and version_id can be found via list_versions. However, it lacks specifics on resource path format or examples, leaving some ambiguity.

Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description explicitly states the tool retrieves a single container version with metadata and slimmed contents, using clear verb 'Gets' and specific resource. It distinguishes from siblings like get_live_version and get_tag by noting the scope and the slimmed nature.
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 alternatives (get_tag/get_trigger/get_variable) and notes their difference (reads workspace draft vs this version). It also advises finding version_id via list_versions, which is helpful for the agent.
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?
Annotations already provide readOnlyHint=true, so the description does not need to reiterate safety. It adds the parameter behavior but no additional traits like permissions or limits. This is adequate but not beyond what is expected.

Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Despite 0% schema coverage, the Args section explains each parameter (numeric ID or resource path) and gives guidance for workspace_id, adding meaning 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?
Clear verb 'lists' and resource 'triggers in a workspace,' specifies 'skeleton fields only,' and distinguishes from 'get_trigger' which provides full configuration.
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 recommends 'get_trigger' for full config and mentions finding workspace_id via 'list_workspaces,' providing clear context, though does not exclude other sibling tools.
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 discloses key behavioral traits: changes are not live until a version is published, and it returns the created variable with its ID. This adds significant context beyond the annotations (readOnlyHint: false, destructiveHint: false), which are consistent with a creation operation.
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 well-structured with a clear summary and an Args section. It is mostly concise, but the Args section repeats parameter names already in the schema; a slightly more streamlined version could omit the redundant parameter headers.
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?
The description covers the creation workflow, parameter requirements, and includes an example. However, it does not address potential errors (e.g., duplicate names), permission requirements, or details about the output schema (though output schema exists). Overall, it is quite complete but has minor gaps.
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?
The schema has 0% description coverage, but the description compensates by explaining each parameter: account_id/container_id accept numeric or path, workspace_id is found via list_workspaces, and the variable body requires 'name', 'type', and often 'parameter', with a detailed example. This provides essential meaning missing from 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 'Creates a variable in the workspace draft.' It uses a specific verb ('creates') and resource ('variable in the workspace draft'), distinguishing it from sibling tools like update_variable and delete_variable.
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 that changes remain in the workspace until a version is published, providing context for use. However, it does not explicitly state when to use this tool versus alternatives (e.g., update_variable) 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 include readOnlyHint=true, consistent with the 'Gets' verb. The description adds that it retrieves 'full configuration including parameters,' providing useful context beyond the annotation. 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?
The description is extremely concise: one sentence for the purpose followed by clear parameter definitions. No redundant words, and the important information is front-loaded.
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 output schema exists and the tool is a simple read with 4 parameters, the description covers all necessary information: what it does, how to get required IDs, and it leverages the output schema for return spec. No gaps.
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?
With schema coverage at 0%, the description fully documents each parameter, adding details like numeric ID or full resource path and how to obtain workspace_id and tag_id from other tools. This adds significant meaning beyond the schema's basic types and titles.
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 'Gets the full configuration of one tag, including parameters.' This is a specific verb-resource combination and distinguishes from sibling tools like list_tags or create_tag.
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 context by advising to find workspace_id via list_workspaces and tag_id via list_tags, implying when to use this tool (when you have IDs). However, it does not explicitly state when not to use it or contrast with alternatives.
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 readOnlyHint annotation is consistent with the listing behavior. The description adds detail by listing exactly which fields are returned (skeleton fields), which goes beyond the annotation's safety implications.
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 very concise, with the main action front-loaded. It lists return fields, provides an alternative tool, and documents arguments in a clear bullet-like format. 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 that an output schema likely exists (context says true), the description still lists the return fields. Parameter documentation is thorough, including how to obtain workspace_id. The guidance to use get_tag for full details completes the context for a listing tool.
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?
Even though the input schema has no descriptions (0% coverage), the description explains each parameter: account_id, container_id, workspace_id, clarifying that they accept numeric IDs or full resource paths, and workspace_id can be found via list_workspaces. This is highly informative beyond the schema's type constraints.
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?
