Latest release: v1.2.0
Disambiguation5/5
Each tool targets a distinct resource or operation, with detailed descriptions that clarify when to use each. Even closely related tools like filter_har_data and get_network_har_file are clearly differentiated by caching behavior. No two tools have overlapping purposes.
Naming Consistency5/5
All tool names follow a consistent verb_noun pattern using lowercase with underscores. The verbs (get, list, lookup, filter, update, upload) are used predictably, and compound names are structured uniformly. No mixing of conventions.
Tool Count5/5
34 tools cover the major areas of the Sauce Labs platform: jobs, builds, devices, tunnels, storage, teams, users, and HAR data. Each tool serves a distinct purpose, and the count is well-scoped for the platform's breadth without unnecessary redundancy.
Completeness3/5
The toolset is strong on reading and querying (many get/lookup tools) but lacks mutation operations such as delete for storage files, stop for jobs, or create for users/teams. This leaves notable gaps in lifecycle management, though the provided tools cover common monitoring and debugging scenarios.
Average 3.7/5 across 34 of 34 tools scored. Lowest: 2.4/5.

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

Behavior1/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description should fully disclose behavioral traits, but it only states what it returns. It lacks information on side effects, permissions, rate limits, or error conditions. The mention of a non-existent filter parameter further reduces transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is front-loaded with purpose but includes a code-style param documentation block that is awkward and unnecessary. It could be more concise by removing the redundant param documentation and focusing on succinct instructions.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has one parameter and an output schema, the description fails to provide complete context. It mentions an optional filter that isn't in the schema, and does not explain the output or any usage constraints. The output schema likely covers return values, but the description is still inadequate.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 0% description coverage, so the description must compensate. It describes the username parameter as required and for authentication, but introduces a 'filter' parameter that does not exist in the schema, causing confusion. This adds minimal value and misleads.
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 returns tunnel IDs or info for tunnels launched by or shared with a user, and clarifies 'tunnel' refers to Sauce Connect. However, it does not explicitly differentiate from sibling tools like get_tunnel_information or get_current_jobs_for_tunnel.
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 mentions an optional 'filter' parameter that is not present in the input schema, which is misleading. It provides no guidance on when to use this tool versus alternatives, and no prerequisites or context for use.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavior. It only describes inputs and a basic output count, but omits side effects, authentication requirements, error handling, or any constraints beyond input requirements.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is functional but includes docstring formatting that adds verbosity. It could be more concise without losing clarity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given an output schema exists, the description does not explain what the return value looks like (e.g., number format, type). It covers inputs adequately but misses output context and error scenarios.
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 0%, but the description provides meaningful explanations for both parameters: username is 'the authentication username of the owner' and tunnel_id is 'the unique identifier of the requested tunnel', going beyond the raw schema.
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 it returns the number of currently running jobs for a specified tunnel, and clarifies the term 'tunnel' refers to Sauce Connect. This distinguishes it from siblings like get_tunnel_information, but lacks explicit differentiation.
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 (e.g., get_tunnels_for_user, get_tunnel_information). It does not mention prerequisites or context for invocation.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must fully disclose behavioral traits. It only states the tool returns 'device information and settings', but does not mention whether results are paginated, require authentication, or if it returns all devices at once. The description is insufficient for safe invocation.
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—one sentence front-loading the key information. Every word is necessary, though more detail could be added without losing conciseness.
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?
With no parameters and an output schema present, the description is adequate but not complete. It fails to mention common list-tool behaviors like ordering, filtering capabilities, or whether results are cached. For a tool with no inputs, the description should provide more context about what 'private devices' means.
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?
There are no parameters (0 params, 100% schema coverage), so baseline is 4. The description adds minimal meaning beyond the schema by specifying the output content ('device information and settings'), but it is vague and does not elaborate on what fields are included.
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 action ('get a list') and the resource ('private devices') and mentions the content ('device information and settings'). It distinguishes from siblings like get_specific_device (which returns a single device) but does not explicitly differentiate from other list tools like get_devices_status or get_real_device_jobs.
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 like get_devices_status (which may return different subsets) or get_specific_device. The description implies using it to list private devices, but provides no context on filtering, prerequisites, or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It only states the tool retrieves details without disclosing whether it is read-only, what permissions are needed, or any side effects. For a retrieval operation, this is minimal.
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 a single paragraph with a clear param docstring. It is front-loaded and efficient, with no extraneous information. It earns a high score for brevity and structure.
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 simple nature of the tool (one parameter, output schema exists), the description is adequate but lacks information about the return value structure or any behavioral details. It does not mention that the operation is read-only or any additional context.
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 has 0% description coverage for the single parameter 'id'. The description compensates by explaining how to obtain the id (URL or Lookup endpoint), which adds meaning beyond the schema. However, it does not describe the format or constraints of the id.
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 action ('retrieves details') and the resource ('service account'). However, it does not differentiate this tool from sibling tools like 'get_account_info' or 'get_user', which might have overlapping purposes.
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 some guidance on how to find the 'id' parameter (URL or Lookup endpoint) but offers no context on when to use this tool over alternatives, nor any preconditions or exclusion criteria.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must disclose behavioral traits. It does not mention that the operation is read-only, any required permissions, rate limits, or side effects. The description focuses solely on input parameters.
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, front-loading the purpose and using a clear docstring format. It avoids unnecessary details while covering essential parameter explanations.
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 adequately covers input parameters, but given that an output schema exists, it does not need to explain return values. However, it lacks information about error conditions, prerequisites, or the scope of the retrieved build details.
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?
The schema has 0% description coverage, so the description fully compensates by explaining build_source with valid values and job_id with a lookup reference. This adds significant meaning beyond the schema's property names.
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 'Retrieve the details related to a specific build' and explains that the build is identified by a job ID. However, it could be more precise about the exact identification mechanism, as it mentions 'its unique ID' but the parameters are build_source and job_id.
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 parameter instructions but does not indicate when to use this tool versus alternatives like get_build or lookup_builds. No guidance on when not to use it or context-specific usage.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must disclose behavioral traits. It mentions requestor-scoping but omits details on read-only nature, pagination, rate limits, or any side effects. For a read operation, this is insufficient.
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, clear sentence with no unnecessary words. It is optimally concise and front-loaded with the core action.
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?
With zero parameters and an output schema present (not shown), the description is minimal but adequate. However, it lacks context about the output structure or any filtering capabilities, which would help an agent plan subsequent steps.
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 and schema coverage is 100%. The description adds no parameter information, which is acceptable since no parameters exist. Baseline of 4 applies.
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 returns a set of files uploaded by the requestor, providing a specific verb and resource. However, it does not explicitly distinguish from sibling tools like get_storage_groups or upload_file_to_storage.
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. The description lacks context on prerequisites, restrictions, or use cases, making it hard for an AI agent to decide when to invoke it.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden. It states jobs are 'actively running' but does not disclose behavioral traits such as auth requirements, rate limits, idempotency, or pagination behavior beyond what parameters imply. The 'actively running' scope is communicated but other impacts are missing.
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 concise: three sentences covering purpose and parameters. No redundant information; every sentence is necessary.
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?
Overall, the description covers the basic purpose and parameter meanings, but lacks details on pagination limits, the meaning of 'LIVE' value for type, and how offset interacts with limit. Output schema exists, so return values are not required, but these gaps reduce completeness.
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 0%, so description must explain parameters. It defines limit (max number), offset (index number, but unclear if zero-based or skip count), and type (manual tests with 'LIVE', but value meaning is ambiguous). While it adds meaning, offset and type descriptions are imprecise.
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 'list of jobs', and the scope 'actively running on real devices in the data center'. It effectively distinguishes from sibling tools like 'get_specific_real_device_job' (specific job) and 'get_current_jobs_for_tunnel' (tunnel-specific).
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 versus alternatives like 'get_recent_jobs' or 'get_current_jobs_for_tunnel'. The description implies it's for active real-device jobs but does not state when not to use it or provide context about job lifecycle.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Without annotations, the description carries the full burden. It only states the operation ('get information') without disclosing read-only nature, side effects, authentication, or error handling. Minimal behavioral context is provided.
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 concise with two sentences: one for purpose and one for the parameter. No extraneous content, front-loaded, and every sentence adds value.
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 output schema exists and the tool is simple (one parameter), the description is adequate but not fully complete. It mentions how to get job_ids but lacks prerequisites or typical usage flow, such as the need to call get_real_device_jobs first.
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 0%, so the description must compensate. It explains job_id as a unique identifier and suggests how to obtain it. This adds meaning but lacks format details (e.g., string length, expected pattern). Baseline is 3 due to the single parameter.
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 retrieves information about a specific job on a real device, using the verb 'Get information' and specifying the resource. It is distinct from siblings like get_real_device_jobs (which lists jobs) and get_specific_real_device_job_asset, but does not explicitly differentiate, making it slightly less than perfect.
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 when a job_id is available and hints at obtaining it via the Get Real Device Jobs endpoint. However, it does not provide explicit when-not-to-use guidance or compare with sibling tools, leaving room for improvement.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. It only states 'returns information' without disclosing read-only nature, auth requirements, or what specific information is returned. Behaviorally opaque.
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 sentences: purpose, term disambiguation, parameter explanations. Efficient, front-loaded, 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?
Covers purpose and parameters, but doesn't explain return value (though output schema exists) or how to obtain tunnel_id. Adequate for a simple lookup, but lacks depth.
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 0%, but description adds basic context: username is 'authentication username of owner', tunnel_id is 'unique identifier of requested tunnel'. Adds some value but remains minimal.
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 'returns information about the specified tunnel' and disambiguates 'tunnel' as referring to Sauce Connect, making purpose specific and distinct from siblings like get_tunnels_for_user.
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 versus alternatives (e.g., get_tunnels_for_user). It implies use for a specific tunnel's details but lacks when-not or comparator context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description should disclose behavioral traits, but it only lists parameters. It does not mention what happens if the build is missing, rate limits, pagination, or ordering of results. The agent lacks crucial runtime context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a block of text with parameter listings; it is functional but not concisely front-loaded. The first sentence states the purpose, but the parameter list is verbose and could be more structured (e.g., grouping filter parameters).
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 13 parameters and no annotations, the description covers all parameter semantics but lacks broader context: no mention of output structure, error handling, or limits. The existence of an output schema helps but is not referenced.
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?
Since schema_description_coverage is 0%, the description compensates by explaining each parameter's purpose and valid values (e.g., build_source lists 'rdc' and 'vdc', boolean filters clarify true/false meaning). This adds significant value beyond the bare 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 tool returns information about jobs for a specified build, using the verb 'Returns' and specifying the resource 'jobs associated with the specified build'. This distinguishes it from sibling tools like get_build (build info) and get_job_details (single job).
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 versus alternatives. It does not state what scenarios warrant filtering or when other endpoints (e.g., get_recent_jobs) might be more appropriate.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, and the description does not disclose any behavioral traits such as whether the update is idempotent, destructive, or requires specific permissions. It only states that it updates settings.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness2/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is verbose, listing all parameters with types, which could be more concise. The initial sentence is clear, but the parameter dump is not streamlined.
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 tool has 9 parameters and no schema descriptions, the description covers them well. However, it lacks overall context about the update behavior (e.g., merge vs replace) and only vaguely mentions the return value.
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, and the description compensates by explaining each parameter in detail, including nested structures like resigning settings. This adds significant value 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 'Update app storage group settings' with a specific verb and resource, and distinguishes itself from sibling tools like get_storage_groups_settings.
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 is given on when to use this tool versus alternatives. For example, it does not mention that get_storage_groups_settings should be used to view current settings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Description only states it returns data, no behavioral details beyond that. No annotations provided, so description should disclose side effects, authentication needs, or error conditions, but it does not.
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 fairly concise, though the parameter documentation is slightly redundant with the schema. No wasted sentences, but could be more streamlined.
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?
Output schema exists, so return value details are not required. However, the description does not mention input validation, error handling, or team existence checks. Adequate but with gaps.
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?
The description adds value by explicitly explaining the 'id' parameter as the team identifier, which compensates for the input schema's lack of description. Only one parameter, well-covered.
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 returns the number of members and lists each member, using a specific verb and resource. It distinguishes from sibling tools like 'get_team' which retrieves team info rather than member list.
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. The description does not mention prerequisites, exclusions, 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.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description bears full responsibility for behavioral disclosure. It only states what the tool does and gives parameter info, but does not reveal side effects, authentication requirements, rate limits, or other behavioral traits.
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 reasonably concise: two sentences for purpose, then parameter details. It is front-loaded with the main action. The parameter descriptions are slightly verbose but clear.
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?
An output schema exists, so the description need not cover return values. The tool is simple with two parameters, and the description covers purpose and parameter details. However, it lacks behavioral context (e.g., read-only nature) and does not mention any prerequisites.
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 adds significant meaning by explaining valid values for 'build_source' ('rdc'/'vdc') and how to obtain 'build_id' via lookup_builds. This goes well beyond the schema's field names.
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 retrieves details of a specific build by its unique ID. The verb 'retrieve' and the resource 'build details' are specific. Among siblings like 'lookup_builds' which lists builds, this tool is distinct for fetching single-build details.
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 details the parameters and valid values ('rdc', 'vdc') and points to 'lookup_builds' for finding IDs. However, it does not explicitly state when to use this tool versus alternatives or exclude contexts where it is not appropriate.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. It implies a read-only operation but does not disclose authorization requirements, rate limits, or side effects. Limited behavioral 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?
Single sentence with no redundancy or irrelevant information. Clearly communicates purpose and scope efficiently.
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 no parameters and an output schema present, the description is largely sufficient. It lacks details on pagination or response structure, but the output schema presumably covers return format.
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?
No parameters exist, so schema coverage is 100%. The description adds context by defining what a group is, though it does not elaborate on authentication scoping beyond 'authenticated requestor'.
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 returns an array of groups, defined as 'apps containing multiple files', and specifies it's for the authenticated requestor. This distinguishes it from sibling tools like get_storage_files.
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 like get_storage_files or get_storage_groups_settings. No exclusions or prerequisites mentioned.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description alone must disclose behavior. It only describes the basic operation without mentioning side effects, idempotency, rate limits, or authentication needs.
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 (two sentences) and front-loaded with the core purpose, though it could be even tighter without losing meaning.
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?
For a simple single-parameter tool with an output schema, the description covers the parameter and provides lookup guidance, but lacks behavioral context that would be expected given no annotations.
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 adds value by explaining group_id is a unique identifier and how to find it, but lacks details on format or 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?
The description clearly states the tool returns settings of an app group by ID, which distinguishes it from siblings like get_storage_groups that likely return group lists.

Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives explicit guidance on how to obtain the group_id via another endpoint, implying when to use this tool (after fetching group IDs), but does not provide when-not-to-use or alternative tools.
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?
With no annotations, the description covers only the basic behavior (returns URLs). It could disclose that this is a read-only operation, but the tool name and context make that clear enough.
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 includes parameter details in a structured way. However, it could separate the parameter documentation more clearly from the main purpose.
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 one-parameter tool with an output schema, the description adequately explains the tool's purpose and parameter. It does not need to detail return values since output schema exists.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description labels client_version as 'Optional' but the schema marks it as required, creating a contradiction. It provides an example value but the mismatch undermines reliability. Schema coverage is 0%, so description should have been accurate.
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 returns download URLs for specific versions of SauceConnect tunnel software, which is distinct from sibling tools that retrieve other tunnel information or job details.

Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage when needing download links for tunnel versions, but lacks explicit guidance on when to use versus alternatives like get_tunnel_information or get_tunnels_for_user.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description should convey behavioral traits. However, it only describes querying and returning data, with no mention of side effects, authentication needs, rate limits, or performance constraints. It assumes a read-only operation but does not explicitly state that.
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 structured with a general purpose overview followed by parameter details in a docstring format. It is not excessively long, but the pseudo-docstring could be more concise.
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 no annotations, the description covers the tool's purpose, filtering options, and that it returns team summaries including IDs. It provides enough context for an agent to use the tool correctly, though it omits details like pagination or limits.
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%, yet the description thoroughly explains both parameters: 'id' as comma-separated IDs for multiple teams, and 'name' as a prefix filter. This adds essential meaning that the schema lacks.
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 that the tool queries the organization and returns the number and summary of matching teams, including IDs. It distinguishes from siblings like 'get_team' by implying it returns multiple teams with filtering, but does not explicitly contrast.
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 explains filtering by name and id, which implies when to use the tool (e.g., looking for teams by name prefix or specific IDs), but it lacks explicit guidance on when not to use it or direct comparisons with sibling tools like 'get_team'.
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?
No annotations provided, so description must carry burden. It implies read-only by stating 'lists', but doesn't explicitly confirm no side effects, rate limits, or permission requirements. Pagination is hinted via limit/offset parameters.
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 main purpose and then lists parameters. It is not overly long but includes some redundancy in parameter descriptions. Could be tightened slightly.
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 output schema exists and no nested objects, the description adequately covers the tool's behavior. It explains filtering options and pagination, but could mention the scope ('existing service accounts') more explicitly as organization-wide.
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 0%, but the description compensates by explaining each parameter's purpose and format (e.g., 'Comma-separated service account IDs', 'usernames that begin with the specified value'). However, the id description is slightly redundant.
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 existing service accounts in your organization' which is a specific verb+resource. It also mentions filtering via query parameters, distinguishing it from sibling tools like get_service_account which retrieves a single account.
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. Siblings like get_service_account and lookup_users exist but no comparison or exclusion criteria are provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. It does not disclose authentication needs, error behavior (e.g., user not found), or rate limits. Only mentions the identifier uniqueness.
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 states purpose, second details the parameter. No redundant words, front-loaded information.

Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It discloses that the tool downloads assets (a read operation), but lacks details about permissions, file size limits, timeouts, or error handling. The behavioral context is adequate but not comprehensive.
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 heading and bullet points, making it scannable. It is reasonably concise for the information provided, though the repeated parameter descriptions could be tightened.
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 mentions that job_id can be looked up using Get Real Device Jobs endpoint, providing some context. However, it does not explain prerequisites, return format, or error cases. Given that an output schema exists, the description's completeness is moderate but not fully self-contained.
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 0%, so the description must compensate. It explains job_id and asset_type, but repeats identical text for both parameters incorrectly for asset_type. It does provide a useful list of possible asset_type values, which adds meaning beyond the schema's bare types. However, the incorrect repetition reduces clarity.
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 'Download a specific asset for a Real Device Cloud (RDC) job,' using a specific verb and resource. It distinguishes from siblings like get_test_assets and get_log_json_file by providing use-case guidance, making its purpose unambiguous.
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 'USE THIS METHOD WHEN' conditions, listing three concrete scenarios. It also explicitly states when not to use it ('For web browser testing on virtual machines, use get_test_assets instead'), offering clear alternatives and exclusions.
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?
No annotations are provided, so the description alone must disclose behavior. It describes a query operation that returns summaries, which implies read-only, but does not explicitly state it is non-destructive. It does not mention rate limits, authentication details beyond 'requesting account', or how pagination works (though offset and limit are parameters). The description is adequate but lacks explicit safety or side-effect information.
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 structured as a docstring with parameters listed, but it is somewhat verbose with full sentences for each parameter. The main purpose is front-loaded in the first sentence. While clear, it could be more concise by using a list format. Every sentence provides value, but the length is higher than necessary.
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 (12 parameters, 1 required) and the presence of an output schema (not detailed in the description), the description adequately covers the tool's purpose and filtering capabilities. It mentions that the returned ID is useful for other APIs. However, it does not describe pagination behavior (e.g., default limit, how to get next page) or the structure of the response beyond 'summary'. Still, it is mostly complete for a query 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?
The input schema has 0% description coverage, so the description carries the full burden of explaining parameters. It provides detailed documentation for each parameter: meaning valid values for build_source and status, usage hints for start/end (e.g., provide both), and clarity that user_id, org_id, etc. filter by ownership and authorization. This adds substantial meaning beyond the bare 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 queries the requesting account and returns a summary of builds, including the ID which is a required parameter for other build-related API calls. It specifies that the results can be narrowed with filtering parameters, and lists required parameter 'build_source' with valid values. This distinguishes it from sibling tools like 'get_build' (single build) or 'lookup_jobs_in_build'.
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 explains that the tool is for listing builds with optional filters, but does not explicitly state when NOT to use it or mention alternatives. There is no guidance on prerequisites or comparisons to sibling tools like 'get_build' or 'get_build_for_job'. Usage is implied but not explicitly differentiated.
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?
No annotations are present, so the description must disclose behavioral traits. It mentions the operation is a query returning count and profiles, but omits details like pagination behavior, what happens with no matches, or that it only queries the requesting account's organization.
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 uses a structured list format for parameters, which is clear, but it is somewhat verbose. Each parameter is explained individually, which adds length. Overall, it is well-organized and front-loaded with the main purpose.
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 has 8 optional parameters and an output schema exists (not shown), the description covers the query behavior and filtering. However, it lacks explicit mention of pagination and the full response structure, which could be covered by the output schema but is not evident here.
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%, but the description fully compensates by explaining each parameter with examples and valid values (e.g., roles, status). This adds significant meaning beyond the raw 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 it queries the organization and returns number of users and basic profiles including IDs. This is distinct from sibling tools like lookup_teams or get_user, making its purpose unambiguous.
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 explains how to filter users using parameters but does not explicitly state when to use this tool versus alternatives like get_user for a single user. No guidance on when not to use it is provided.
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?
No annotations provided; description implies read-only but does not explicitly state no side effects or disclosure of behavior beyond the purpose.
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 sentences plus a concise param doc line, front-loaded with main purpose, no unnecessary 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?
Simple tool with output schema; description covers purpose, param, and use case sufficiently, though could mention the default limit of 5 more explicitly.
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 param description adds crucial details: it's an integer limit with a maximum of 100, which is absent from the schema (0% coverage).
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 it retrieves recent jobs for the current user, distinguishing from sibling tools like get_job_details or get_build_for_job.

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?
With no annotations, the description carries full burden. It discloses return of a unique file ID, supported formats, 4GB size limit, HTTP status codes, and project creation behavior. However, it does not mention authentication or rate limits.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is somewhat verbose with a list of :param entries, but it is front-loaded with the main purpose. It could be more concise without losing 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 tool with 5 required parameters and no output schema, the description covers input constraints and return values (201 Created). It lacks explanation of how the file ID is used later, but overall it is fairly 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?
Schema coverage is 0%, but the description explains each parameter in detail, including constraints for tags (length, characters, count) and project_name (characters, max length, auto-creation). This adds significant value beyond the bare 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 does not provide explicit guidance on when to use this tool versus alternatives such as get_storage_files. It only implies usage through the upload action, but no when-not or exclusion criteria.
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?
No annotations provided; description discloses caching behavior, first vs subsequent calls, and key difference. Lacks details on side effects or memory limits but adequate for a read-like filter.
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?
Well-structured with summary, key difference, behavior, parameters, and examples. Slightly verbose in repeating caching behavior, but every section adds value.
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 purpose, usage, parameters, and caching behavior. Lacks return structure details, but examples and parameter descriptions provide enough context for correct invocation.
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%; description adds meaning by listing parameters with brief explanations, predefined categories, and examples, compensating fully for missing 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?
Clearly states it filters HAR data with in-memory caching, distinguishes from sibling get_network_har_file by highlighting caching behavior.

Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly describes when to use (for multiple queries) vs when not (first call downloads), and names the alternative tool. Examples reinforce usage.
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?
With no annotations provided, the description fully discloses behavioral traits: the inUseBy field exposure condition (private devices + permissions), the available states list, and the use of descriptor as an identifier for other tools. This is comprehensive.
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 paragraphs, a state list, and a note. It is informative but slightly lengthy; however, every sentence adds value. Could be slightly more concise but still good.
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 an output schema exists, the description adequately covers the output fields, special behaviors, state meanings, and cross-reference to a related tool. It is complete for its simplicity.
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 0 parameters, and the schema coverage is 100% (empty schema). According to guidelines, the baseline is 4. The description adds no parameter info because none exist, which 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 returns a list of devices with their states, and differentiates itself from get_specific_device by noting that the latter provides detailed specifications. It also implies a lightweight overview purpose.
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 explicitly tells when to use get_specific_device for detailed specs, but does not mention alternatives like get_private_devices, which is a sibling tool specifically for private devices. The context is clear but lacks exclusions for all related siblings.
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?
Describes behavior: returns structured JSON log, only for VDC jobs, and explains failure scenario. No annotations exist, so description carries full burden. It could add that operation is read-only but covers key points.
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?
Well-structured with clear sections (IMPORTANT, param, return). The 'If this method fails' sentence adds value but slightly increases length. Generally efficient.
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 single parameter and presence of output schema, the description provides sufficient context. It explains return format and key constraints, making the tool fully understandable.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
