Disambiguation4/5
Most tools have distinct purposes, but there is some overlap that could cause confusion. For example, browse_repo and browse_repo_recursive both explore Git repositories, with the latter being a more comprehensive version, which might lead to misselection if an agent doesn't carefully read descriptions. Similarly, browse_s3 and browse_s3_logs both browse S3, but the latter is specialized for logs, creating a potential boundary issue. However, the majority of tools, like those for DAG management, EMR, Confluence, and Azure DevOps, are clearly differentiated.
Naming Consistency5/5
Tool names follow a highly consistent verb_noun pattern throughout, such as browse_repo, cancel_job_run, create_confluence_page, and get_dag_run_details. There are no deviations in naming conventions (e.g., no mixing of camelCase or other styles), making the set predictable and easy to understand. This consistency aids agents in quickly identifying tool purposes.
Tool Count2/5
With 44 tools, the count is excessive for a single server, even given its broad scope covering Git, S3, EMR, Airflow DAGs, Confluence, and Azure DevOps. This many tools can overwhelm agents, increasing cognitive load and the risk of misselection. A more modular approach with separate servers for each domain (e.g., one for DAGs, one for Confluence) would be more appropriate, as the current set feels heavy and unfocused.
Completeness5/5
The tool set provides comprehensive coverage across its integrated domains, with no obvious gaps. For Git, it includes browsing and reading files; for S3, browsing, reading, and listing; for EMR, full lifecycle management (create, list, stop, cancel, delete, cost analysis); for Airflow DAGs, CRUD operations (trigger, pause, unpause), monitoring, and diagnostics; for Confluence, CRUD pages and search; and for Azure DevOps, repository and sprint management. Each domain is well-covered, enabling agents to handle end-to-end workflows without dead ends.

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

Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions pagination and default values, which is helpful, but doesn't cover critical aspects like rate limits, authentication requirements, error conditions, or whether this is a read-only operation. The description doesn't contradict any annotations (since none exist), but it leaves significant behavioral gaps.
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 efficiently structured with a clear purpose statement followed by parameter explanations and return value information. Every sentence adds value, though the 'Args:' and 'Returns:' formatting could be more integrated with natural language. It's appropriately sized for a tool with four 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 the tool's moderate complexity (listing operation with pagination and filtering), no annotations, and an output schema (which handles return values), the description is minimally adequate. It covers parameters well but lacks behavioral context like error handling, rate limits, and usage guidelines. The presence of an output schema reduces the need to explain return format, but more operational guidance would be helpful.
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 well by explaining all four parameters: space_key (with default from config), max_results (with range), page_type (with enum values), and start (pagination offset). It provides meaningful context beyond the schema's titles, though it could elaborate on the 'ACTIVATE from config' default behavior.
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's purpose as 'List all pages in a Confluence space' with a specific verb ('List') and resource ('pages in a Confluence space'). It distinguishes itself from siblings like 'get_child_pages' or 'search_confluence' by focusing on space-level listing rather than page-specific operations or search. However, it doesn't explicitly contrast with these siblings in the description text.
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 like 'get_child_pages' or 'search_confluence'. It mentions pagination but doesn't explain when pagination is needed or how to handle large result sets. There's no discussion of prerequisites, such as needing space access permissions.
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 of behavioral disclosure. It mentions that the tool 'Returns a list of labels,' which indicates a read-only operation, but fails to address other critical aspects such as authentication requirements, error handling (e.g., invalid page_id), rate limits, or pagination behavior. For a tool with no annotation coverage, this leaves significant gaps in understanding its behavior.
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 appropriately sized and front-loaded, with the core purpose stated first ('Get all labels (tags) on a Confluence page.'). The additional sentences provide useful context without redundancy. However, the formatting with 'Args:' and 'Returns' could be more integrated, slightly affecting 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 tool's low complexity (1 parameter) and the presence of an output schema (which handles return values), the description is somewhat complete but has gaps. It covers the basic purpose and usage hint but lacks details on behavioral aspects like error handling or authentication, which are important for a tool with no annotations. This results in a minimally adequate but incomplete description.
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, with only one parameter ('page_id') documented structurally. The description adds minimal semantics by stating 'page_id: The page ID,' which restates the schema's title without providing additional context (e.g., format, source, or validation rules). Since schema coverage is low, the description does not adequately compensate, resulting in a baseline score.
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's purpose: 'Get all labels (tags) on a Confluence page.' It specifies the verb ('Get') and resource ('labels on a Confluence page'), making the action unambiguous. However, it does not explicitly differentiate from sibling tools like 'get_page_attachments' or 'get_page_comments', which follow a similar pattern but target different page attributes.
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 implied usage guidance by stating it's 'Useful for finding related pages or understanding page categorization.' This suggests contexts where the tool is applicable, such as content organization or navigation. However, it lacks explicit guidance on when to use this tool versus alternatives (e.g., 'search_confluence' for broader queries) or any exclusions, leaving room for interpretation.
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 of behavioral disclosure. It mentions the return format ('list of child pages with titles and IDs') but lacks critical details: whether this is a read-only operation, if it requires authentication, any rate limits, pagination behavior beyond the max_results default, or error conditions (e.g., invalid page_id). For a tool with no annotation coverage, this leaves significant gaps in understanding its behavior.
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 efficiently structured with a clear purpose statement followed by bullet-pointed parameter explanations and a return statement. Every sentence adds value: the first defines the tool's function, the parameter descriptions clarify inputs, and the return statement outlines outputs. There is no redundant or verbose language.
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 no annotations, 3 parameters with 0% schema coverage, and an output schema present, the description is moderately complete. It covers the basic purpose and parameters but lacks behavioral context (e.g., safety, errors, pagination). The output schema likely details return values, so the description doesn't need to explain returns extensively, but it should address more operational aspects for full completeness.
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%, so the description must compensate. It adds meaningful context for all three parameters: page_id is explained as 'The parent page ID', include_content clarifies it provides 'a short content preview for each child', and max_results specifies 'Max children to return (default 50)'. This goes beyond the schema's basic titles and types, though it doesn't detail format constraints (e.g., page_id structure) or edge cases.
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 specific action ('List all child pages') and identifies the target resource ('of a given parent page'). It distinguishes itself from sibling tools like 'get_space_pages' or 'search_confluence' by focusing on hierarchical page relationships rather than space-wide listing or search functionality.
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 like 'get_space_pages' or 'search_confluence'. It doesn't mention prerequisites, such as needing a valid parent page ID, or exclusions, like not being suitable for non-hierarchical content. The only implicit context is the need for a parent page, but no explicit usage instructions are given.
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 provided, the description carries the full burden of behavioral disclosure. It mentions the return format ('comments with author, date, and content') and a default value for max_results, but doesn't cover important aspects like pagination behavior, error handling, authentication requirements, rate limits, or whether this is a read-only operation. For a tool with zero annotation coverage, this leaves significant gaps.
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 efficiently structured with a clear purpose statement, parameter explanations, and a usage benefit - all in just four sentences. Every sentence adds value without redundancy, and the information is front-loaded with the core functionality stated first.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given that an output schema exists (which handles return value documentation), the description provides adequate context for a relatively simple read operation. It covers the purpose, parameters, and basic use case. However, for a tool with no annotations, it could benefit from more behavioral transparency about how the tool actually works beyond just what it returns.
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 meaningful context for both parameters beyond what the schema provides (which has 0% description coverage). It explains that 'page_id' identifies the Confluence page and that 'max_results' controls how many comments to return with a default of 25. This compensates well for the lack of schema descriptions, though it doesn't specify format requirements for page_id or constraints on max_results.
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's purpose with a specific verb ('Get') and resource ('comments on a Confluence page'), making it immediately understandable. However, it doesn't explicitly differentiate from sibling tools like 'get_page_content' or 'search_confluence', which could also involve page-related operations.
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 implied usage context by stating the tool is 'useful for understanding discussions and context around a page,' which suggests when it might be appropriate. However, it lacks explicit guidance on when to use this tool versus alternatives like 'get_page_content' or 'search_confluence,' and doesn't mention any 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?
With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions the return format ('list of job runs with status, timing and duration') but doesn't cover critical aspects like whether this is a read-only operation, pagination behavior, rate limits, authentication requirements, or error conditions. For a tool with 5 parameters and no annotations, this leaves significant gaps.
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 perfectly structured and front-loaded: purpose statement first, followed by organized parameter documentation with clear formatting. Every sentence earns its place, with no wasted words or redundant information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's moderate complexity (5 parameters, 1 required), 0% schema coverage, no annotations, but presence of an output schema, the description does well by thoroughly documenting all parameters. The output schema means return values don't need explanation, but behavioral aspects like safety and constraints could be more complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description compensates well by explaining all 5 parameters in the Args section, including format examples (e.g., ISO date, comma-separated states), default values, and important usage guidance for 'env'. This adds substantial meaning beyond what the bare schema provides.
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 verb ('List') and resource ('job runs for an EMR Serverless application'), making the purpose immediately understandable. However, it doesn't explicitly differentiate from sibling tools like 'get_job_run_details' or 'list_emr_applications', which would be needed for a perfect score.
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 implied usage context through the 'env' parameter guidance ('IMPORTANT: Do NOT guess or default. Ask the user which environment if not specified'), which suggests when to use this tool versus alternatives. However, it lacks explicit when/when-not guidance or named alternatives for filtering job runs.
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 provided, the description carries the full burden of behavioral disclosure. It mentions the tool triggers a DAG run and returns a confirmation with a run ID, but lacks details on permissions, side effects, rate limits, or error handling. For a mutation tool with zero annotation coverage, this is a significant gap.
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 efficiently structured with a clear purpose statement followed by parameter explanations in a bullet-like format. Every sentence adds value, and the IMPORTANT note is appropriately emphasized without unnecessary verbosity.
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's complexity (a mutation with 3 parameters), no annotations, and an output schema present, the description is adequate but incomplete. It covers the basics of what the tool does and parameter semantics, but lacks behavioral context like permissions or side effects, which are crucial for safe usage.
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 substantial meaning beyond the input schema, which has 0% description coverage. It explains 'dag_id' as 'The DAG to trigger', 'env' with allowed values and critical usage guidance, and 'conf' as an optional JSON string. This compensates well for the schema's lack of documentation, though it doesn't fully detail all parameter nuances.
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 ('Manually trigger a DAG run') and resource ('a DAG'), making the purpose immediately understandable. However, it doesn't differentiate from sibling tools like 'pause_dag' or 'unpause_dag' beyond the triggering action, which is why it doesn't reach a score of 5.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides clear context for the 'env' parameter with explicit guidance ('IMPORTANT: Do NOT guess or default. Ask the user which environment if not specified'), which helps guide usage. However, it lacks explicit alternatives or when-not-to-use guidance compared to siblings like 'pause_dag', preventing a score of 5.
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 provided, the description carries the full burden. It states this is a list operation (implying read-only) and describes the return format, which is helpful. However, it doesn't mention pagination behavior, rate limits, authentication requirements, or error conditions that would be important for a production tool.
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 perfectly structured and front-loaded: the first sentence states the core purpose, followed by clear parameter explanations and return value description. Every sentence earns its place with zero wasted words or redundancy.
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 relatively simple read operation with 2 parameters and an output schema, the description is mostly complete. It explains what the tool does, documents the parameters, and describes the return format. The main gap is lack of behavioral context like pagination or error handling, but the output schema likely covers the return structure.
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%, so the description must compensate. It clearly explains both parameters: page_id identifies the target page, and max_results controls the return limit with its default value. This adds meaningful context beyond the bare schema, though it doesn't specify format requirements for page_id.
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 specific action ('List all file attachments') and resource ('on a Confluence page'), distinguishing it from siblings like get_page_content or get_page_comments which handle different page elements. The verb 'List' is precise and the scope 'all file attachments' is unambiguous.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives. While it's clear this tool is for Confluence page attachments, there's no mention of when you'd use this versus other Confluence tools like get_page_content or search_confluence, nor any prerequisites or constraints beyond what's in the parameters.
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 full burden. It mentions the tool updates content and can append, but lacks critical behavioral details: required permissions, whether updates are reversible, rate limits, or what 'confirmation of the update' entails. For a mutation tool with zero annotation coverage, this is a significant gap.
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 efficiently structured with a clear purpose statement followed by bullet-like parameter explanations. Every sentence adds value: the first states the action, and the subsequent lines clarify parameter roles and behaviors. No wasted words, and information is front-loaded.
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's complexity (mutation with 4 parameters), no annotations, and an output schema present, the description is partially complete. It covers parameters well but lacks behavioral context (permissions, side effects). The output schema handles return values, so the description's focus on parameters is appropriate, but more behavioral disclosure would improve completeness.
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. It provides clear semantics for all 4 parameters: 'page_id' identifies the target, 'body' specifies new content format, 'title' explains optional behavior, and 'append' defines a key behavioral flag. This adds substantial 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 specific action ('Update an existing Confluence page's content'), identifies the resource ('Confluence page'), and distinguishes it from sibling tools like 'create_confluence_page' (creation vs. update). The verb+resource combination is precise and 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 implies usage context through the parameter descriptions (e.g., 'If omitted, keeps the existing title'), but does not explicitly state when to use this tool versus alternatives like 'create_confluence_page' or 'get_page_content'. No explicit guidance on prerequisites or exclusions 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?
With no annotations provided, the description carries full burden. It discloses the read-only nature ('Read'), mentions performance characteristics ('slower'), and describes output behavior ('converted to clean readable text'). However, it doesn't cover important behavioral aspects like error conditions, rate limits, authentication requirements, or pagination behavior.
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 perfectly structured with a clear purpose statement followed by a well-organized parameter explanation. Every sentence earns its place - the first sentence states the core function, and the parameter explanations are essential for proper usage. No wasted words or redundancy.
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 moderate complexity (4 parameters, read operation) and the presence of an output schema, the description provides good coverage. It explains the core functionality and parameters well, though it could benefit from more behavioral context about errors or limitations. The output schema handles return value documentation, so the description appropriately focuses on usage.
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 4 parameters with clear semantics: page_id vs title trade-offs, space_key requirement logic, and include_metadata default behavior. The 'Args:' section provides essential context beyond what the bare schema offers.
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 specific action ('Read the full content'), target resource ('a Confluence page'), and output format ('converted to clean readable text'). It distinguishes itself from siblings like get_page_attachments or get_page_comments by focusing on page content specifically.
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 implied usage guidance through parameter explanations (e.g., 'Provide this OR title', 'slower, requires space_key'), but doesn't explicitly state when to use this tool versus alternatives like search_confluence or get_child_pages. No clear exclusions or sibling comparisons are 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?
With no annotations provided, the description carries the full burden of behavioral disclosure. It explains what the tool does (aggregates resource usage across job runs) and includes important operational guidance about the 'env' parameter. However, it lacks details on permissions needed, rate limits, error conditions, or whether this is a read-only operation (though implied by 'Get').
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, aggregation details, usage context, parameter explanations, and return information. Every sentence adds value, though the 'IMPORTANT' note about the 'env' parameter could be integrated more smoothly. The text is appropriately sized for a tool with three parameters.
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 moderate complexity (3 parameters, no annotations, but with output schema), the description provides good coverage. It explains the tool's purpose, parameters, and return value ('Returns a cost summary with per-job and total resource usage'). The presence of an output schema means the description doesn't need to detail the return structure, making this reasonably 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 providing clear semantic explanations for all three parameters. It explains that 'application_id' is optional and filters to one application, 'days' specifies the lookback period with a default, and 'env' is the target environment with specific valid values and important usage guidance.
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's purpose with specific verbs ('Get a summary', 'Aggregates') and resources ('EMR Serverless resource usage and estimated costs', 'vCPU hours, memory GB-hours, and storage GB-hours across recent job runs'). It distinguishes itself from sibling tools by focusing on cost analysis rather than browsing, listing, or managing resources.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides clear context for when to use this tool ('Useful for understanding compute costs'), but does not explicitly mention when not to use it or name specific alternatives. The guidance on the 'env' parameter ('IMPORTANT: Do NOT guess or default. Ask the user which environment if not specified') offers operational direction but not tool-selection advice.
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 carries the full burden. It discloses that content can be HTML or plain text (with formatting details) and mentions the return format (confirmation with page ID and URL). However, it does not cover important behavioral aspects like required permissions, error handling, rate limits, or whether the operation is idempotent, leaving gaps for a mutation tool.
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 well-structured and front-loaded with the core purpose, followed by usage examples, parameter details, and return information. Every sentence adds value without redundancy, and the bullet-point style for parameters enhances readability while maintaining brevity.
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 (mutation with 4 parameters), no annotations, and an output schema (which covers return values), the description does a good job but has minor gaps. It explains parameters thoroughly and mentions returns, but lacks details on permissions, errors, or idempotency, which are important for a creation tool. The output schema helps, but behavioral context could be more 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 description coverage is 0%, so the description must compensate fully. It provides detailed semantics for all four parameters: explains uniqueness for 'title', content formats for 'body', default behavior for 'space_key', and optional nesting for 'parent_page_id'. This adds significant value beyond the bare schema, covering all parameters effectively.
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's purpose with a specific verb ('Create') and resource ('new Confluence page'). It distinguishes from sibling tools like 'update_confluence_page' by focusing on creation rather than modification. The examples (incident reports, runbook entries, etc.) further clarify the intended use cases.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides clear context on when to use this tool ('to create incident reports, runbook entries, meeting notes, or any documentation'), but does not explicitly state when not to use it or mention alternatives like 'update_confluence_page' for modifying existing pages. The guidance is helpful but lacks explicit exclusions or comparisons.
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 carries the full burden. It discloses that the tool returns items 'ordered by priority with state and effort,' which adds useful behavioral context beyond the input schema. However, it doesn't mention potential limitations like pagination, error conditions, or authentication requirements, leaving some gaps for a tool with no annotation coverage.
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 well-structured and front-loaded: it starts with the purpose, then usage guidelines, followed by parameter explanations. Every sentence earns its place with no redundancy. It's appropriately sized for the tool's complexity, making it easy for an agent to parse quickly.
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 an output schema (which handles return values), no annotations, and 3 parameters with 0% schema coverage, the description does a good job. It covers purpose, usage, and parameter semantics adequately. However, for a tool with no annotations, it could benefit from more behavioral details like error handling or rate limits, keeping it from a perfect score.
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%, so the description must compensate. It adds meaning by explaining each parameter: 'project: Project name (default from config)', 'team: Team name (default from config)', and 'max_results: Maximum items to return (default 50).' This clarifies the purpose and defaults, though it doesn't provide format details or constraints. With 3 parameters, this is a strong effort that significantly enhances understanding.
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's purpose: 'Get backlog items (PBIs/User Stories not in the current sprint).' It specifies the verb ('Get'), resource ('backlog items'), and scope ('not in the current sprint'), distinguishing it from sibling tools like get_current_sprint and get_sprint_work_items. This is specific and 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 usage guidelines: 'USE THIS TOOL when the user asks about the backlog, upcoming work, 'what's next?', 'what's not in the sprint?', or items waiting to be picked up.' It gives clear examples of when to use this tool, helping the agent distinguish it from alternatives like get_current_sprint. No exclusions are mentioned, but the guidance is comprehensive.
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 provided, the description carries the full burden. It describes what the tool returns ('complete work item details including description, acceptance criteria, parent/child links, and all metadata fields') but doesn't mention authentication requirements, rate limits, error conditions, or whether this is a read-only operation. It provides some behavioral context but leaves important operational details unspecified.
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 efficiently structured with a clear purpose statement, usage guidelines section, parameter explanations, and return value description. Every sentence serves a distinct purpose with no wasted words, and information is logically organized and front-loaded.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has an output schema (which handles return values), no annotations, and 2 parameters with good description coverage, the description is reasonably complete. It explains what the tool does, when to use it, what parameters mean, and what to expect in return. The main gap is lack of operational context like authentication or error handling.
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 well by explaining both parameters: 'work_item_id: The numeric work item ID (e.g. 12345)' and 'project: Project name (default from config).' It provides concrete examples and default behavior, adding significant value beyond the bare schema which only shows types and requirements.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description explicitly states 'Get full details of a single work item' with specific resource types listed (PBI, Task, Bug, Feature, Epic). It clearly distinguishes this from sibling tools by focusing on retrieving complete details for a single item by ID, unlike tools like get_backlog or get_sprint_work_items which handle collections.
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 with 'USE THIS TOOL when the user asks about a specific work item by ID, wants the description, acceptance criteria, history, or full details.' This gives clear conditions for when to use this tool versus alternatives, addressing the specific use case scenarios.
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 carries the full burden. It discloses that the tool returns a list of repositories with specific fields (name, default branch, size, URL), which is useful behavioral context. However, it doesn't mention potential limitations like pagination, rate limits, authentication needs, or error conditions, leaving gaps for a tool with no annotation coverage.
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 well-structured and front-loaded with the core purpose, followed by usage guidelines, parameter details, and return information. Every sentence adds value without redundancy, making it efficient and easy to parse.
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 1 parameter with no annotations but an output schema (which handles return values), the description is largely complete. It covers purpose, usage, parameter semantics, and return format. However, it lacks details on behavioral aspects like error handling or constraints, which would be beneficial since annotations are absent.
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 input schema has 1 parameter with 0% description coverage. The description adds meaningful semantics by explaining that 'project' is the 'Project name (default: Activate from config),' clarifying its purpose and default behavior. This compensates well for the low schema coverage, though it doesn't detail what 'Activate from config' entails.
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 specific action ('List all Git repositories') and resource ('in the Azure DevOps project'), distinguishing it from sibling tools like browse_repo (which explores files) and other unrelated tools. It provides a complete picture of what the tool does.
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 explicitly states 'USE THIS TOOL when the user asks about repos, code repositories, or wants to browse source code in Azure DevOps / TFS,' providing clear when-to-use guidance. It also mentions an alternative tool ('Use browse_repo(repo_name='...') to explore a repo's files') for related but different tasks.
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 provided, the description carries the full burden and does well by disclosing key behavioral traits: it specifies the return format ('formatted table'), mentions default values for parameters, and includes an important instruction about not guessing the environment. However, it doesn't cover aspects like rate limits or error handling.
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 appropriately sized and front-loaded: the first sentence states the core purpose, followed by a structured breakdown of args and returns. Every sentence adds value without redundancy, making it efficient and easy to parse.
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 3 parameters, no annotations, but an output schema, the description is quite complete: it covers purpose, parameters, and return format. The output schema likely handles return values, so the description doesn't need to detail them further. Minor gaps include lack of error or edge-case handling.
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?
Given 0% schema description coverage, the description fully compensates by explaining all three parameters: 'env' with allowed values and a critical usage note, 'limit' with its default, and 'only_active' with its filtering logic. It 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 the specific action ('List all DAGs') and resource ('in the MWAA environment'), distinguishing it from siblings like list_dag_runs, list_emr_applications, or list_job_runs. It precisely identifies what the tool does without ambiguity.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides clear context for usage by specifying the target environment and filtering options, but it does not explicitly state when to use this tool versus alternatives like get_dags_status_dashboard or list_dag_runs. It offers guidance on parameter usage but lacks sibling differentiation.
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 provided, the description carries the full burden of behavioral disclosure. It effectively describes key behaviors: the DAG remains visible in the UI, scheduled runs are prevented, and already-running runs continue. It also hints at a confirmation return. However, it lacks details on permissions, error conditions, or rate limits, which are important for a mutation tool.
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 well-structured and front-loaded with the core purpose, followed by behavioral details and parameter explanations. Every sentence adds value, with no wasted words, making it efficient and easy to parse.
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 (a mutation with 2 parameters, no annotations, but an output schema), the description is mostly complete. It covers purpose, behavior, and parameters well. However, as a mutation tool, it could benefit from more details on side effects or error handling, though the output schema may cover return values.
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 clearly explains both parameters: 'dag_id' as the DAG to pause and 'env' with its allowed values ('dev', 'uat', 'test', 'prod') and a critical usage instruction (asking the user if not specified). This adds significant 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 the tool's purpose with a specific verb ('pause') and resource ('a DAG'), and distinguishes it from sibling tools like 'unpause_dag' and 'trigger_dag'. It explains that it prevents future scheduled runs while allowing current runs to complete, which is precise and actionable.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides clear context on when to use this tool (to pause a DAG and prevent future scheduled runs) and includes an important usage note for the 'env' parameter (asking the user if not specified). However, it does not explicitly state when not to use it or compare it to alternatives like 'unpause_dag', which limits the score.
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 are provided, so the description carries full burden. It discloses key behavioral traits: the cancellation is asynchronous, with state transitions (CANCELLING → CANCELLED). It also warns about the 'env' parameter requiring explicit user input. However, it doesn't mention permissions, rate limits, or error conditions.
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?
Well-structured and front-loaded: purpose first, usage guidelines second, parameter details third, return value last. Every sentence earns its place with no wasted words, and the formatting (Args/Returns sections) enhances readability.
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, 0% schema coverage, but an output schema exists, the description is quite complete. It covers purpose, usage, parameters, and behavioral context. The output schema handles return values, so the description's 'Returns confirmation...' is sufficient. Minor gaps include lack of error handling or auth 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?
Schema description coverage is 0%, so the description must compensate.

Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden and does well: it discloses the tool's purpose (directory listing), default values (prefix, bucket, max_items), and a critical behavioral constraint (must ask user for env if unspecified). It doesn't mention rate limits or auth needs, but covers core behavior adequately.
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 a purpose statement, parameter details in bullet-like format, and a returns statement. Every sentence adds value, though the 'IMPORTANT' note could be integrated more smoothly. Slightly verbose but efficient overall.
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 4 parameters with 0% schema coverage and no annotations, the description provides complete context: purpose, parameter details with defaults and examples, usage rules, and output explanation. With an output schema present, it doesn't need to detail return values, making this comprehensive.
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 does: each parameter (prefix, bucket, max_items, env) is explained with semantics, defaults, examples (e.g., 'spark-logs/'), and usage guidance (e.g., 'Ask the user which environment'). 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 specific action ('browse', 'navigate') and resource ('S3 log directory structure', 'folders to find logs'). It distinguishes from siblings like 'browse_s3' (general S3 browsing) and 'list_s3_recursive' (recursive listing) by focusing on log directories with navigation guidance.
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?
Explicit guidance is provided: 'Use the output to navigate deeper' explains iterative usage, and 'IMPORTANT: Do NOT guess or default. Ask the user which environment if not specified' gives clear when-to-use rules. It implicitly contrasts with 'browse_s3' by specifying log-focused browsing.
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 provided, the description carries the full burden of behavioral disclosure. It effectively describes what the tool returns ('current sprint name, date range, and time remaining'), mentions configurable defaults for parameters, and clarifies the scope (active sprint only). However, it doesn't address potential edge cases like what happens when no sprint is active or authentication requirements.
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 well-structured with clear sections (purpose, usage guidelines, parameters, returns, related tools). Every sentence adds value with no redundancy. The 'USE THIS TOOL' section efficiently lists multiple query examples, and the parameter explanations are direct and informative.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's moderate complexity (2 optional parameters, no annotations, but has output schema), the description provides complete context. It covers purpose, usage scenarios, parameter semantics, return values, and relationship to sibling tools. The existence of an output schema means the description doesn't need to detail return structure, which it appropriately avoids.
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 well by explaining both parameters ('project' and 'team') and indicating they have defaults from config. It provides meaningful context about when these parameters are needed, though it doesn't specify exact config sources or format requirements.
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's purpose with specific verbs ('get the current sprint/iteration') and resources ('dates and summary'). It distinguishes itself from siblings by focusing on the active sprint only, not historical or future sprints, and explicitly mentions get_sprint_work_items as a complementary tool for detailed sprint content.
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 usage guidelines with a dedicated 'USE THIS TOOL' section listing specific user query examples ('what sprint are we in?', 'current iteration', etc.). It also clearly distinguishes when to use this tool versus get_sprint_work_items for different types of sprint information.
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 provided, the description carries the full burden of behavioral disclosure. It effectively describes key behaviors: it's a read-only operation (implied by 'Get'), returns formatted output with specific content (e.g., summary counts, highlighted failed DAGs), and includes important constraints like requiring explicit environment specification ('IMPORTANT: Do NOT guess or default'). However, it doesn't mention potential rate limits or authentication requirements.
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 clear sections (purpose, usage guidelines, output details, args, returns) and front-loads key information. Most sentences earn their place, though some phrasing like 'the go-to tool for any overview question' is slightly verbose. Overall, it's appropriately sized for the tool's complexity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's moderate complexity (2 parameters, no annotations, but with output schema), the description is highly complete. It covers purpose, usage context, parameter semantics, and output format. The presence of an output schema means the description doesn't need to detail return values, and it adequately addresses all other aspects needed for effective tool selection and 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 description coverage is 0%, so the description must fully compensate. It provides detailed semantics for both parameters: 'env' is explained as 'Target environment' with valid values listed and a critical usage note, and 'limit' is described as 'Maximum number of DAGs to return' with its default value. 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 explicitly states the tool's purpose: 'Get a complete status dashboard of ALL DAGs.' It specifies the verb ('Get'), resource ('status dashboard'), and scope ('ALL DAGs'), clearly distinguishing it from sibling tools like list_dags or get_dag_run_details by emphasizing comprehensive overview functionality.
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 usage guidelines with a dedicated 'USE THIS TOOL when the user asks:' section listing five specific query patterns. It clearly defines when to use this tool versus alternatives by positioning it as the 'go-to tool for any overview question,' differentiating it from more specific sibling tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It effectively describes key behaviors: it's a read operation (implied by 'Read'), returns raw log text trimmed to the last N lines, and includes important constraints like not guessing the 'env' parameter. However, it doesn't mention potential errors, 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 well-structured with clear sections (purpose, important notes, args, returns) and uses bullet points for readability. While slightly longer due to detailed examples, every sentence adds value (e.g., EMR debugging steps, parameter warnings). Minor trimming could improve conciseness without losing clarity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (6 parameters, 0% schema coverage, no annotations) and the presence of an output schema, the description is highly complete. It covers purpose, usage guidelines, parameter semantics, and behavioral aspects like output trimming. The output schema handles return values, so the description appropriately focuses on context and usage.
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 description coverage is 0%, so the description must fully compensate. It successfully adds meaning for all parameters: explains 'dag_id', 'dag_run_id', and 'task_id' as identifiers; details 'env' options and critical usage warning; clarifies 'try_number' as attempt count with default; and specifies 'tail_lines' as number of lines from the end with default. This goes well 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 specific action ('Read the Airflow log for a specific task attempt') and resource ('Airflow log'), distinguishing it from siblings like 'read_spark_driver_log' or 'get_dag_run_details'. It precisely defines the tool's function without tautology.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides explicit guidance on when to use this tool, including specific examples for EMR debugging (e.g., to find EMR application IDs or job_run_ids). It also names an alternative tool ('read_spark_driver_log') for further steps, clearly differentiating use cases.
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 provided, the description carries the full burden of behavioral disclosure. It effectively describes key behaviors: it's a read operation (implied by 'Get'), returns interactive numbered lists, and includes important constraints like the 'IMPORTANT: Do NOT guess or default' warning for the 'env' parameter. However, it doesn't mention rate limits, authentication requirements, or error handling scenarios.
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 clear sections: purpose statement, usage guidelines, parameter explanations, and return format. It's appropriately sized for a 4-parameter tool with no annotations. Minor improvement could be made by slightly tightening the language, but 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 the tool's complexity (4 parameters, no annotations, but with output schema), the description is complete. It covers purpose, usage, all parameters with semantics, and return behavior. The output schema existence means the description doesn't need to detail return values, and it appropriately focuses on how to present results to users.
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 providing detailed parameter semantics. It explains all 4 parameters: 'env' (target environments with specific values and an important usage warning), 'dag_id' (optional filter), 'date' (valid values and default), and 'limit' (purpose and default). 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's purpose: 'Get DAG runs for today, yesterday, last week, or a specific date.' It specifies the verb ('Get'), resource ('DAG runs'), and scope (time-based filtering). It distinguishes from sibling tools like 'get_dag_run_details' (which provides deeper investigation) and 'list_dags' (which lists DAGs rather than runs).
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 usage guidance: 'This is the go-to tool when the user asks about DAG runs, processing status, or historical failures.' It also specifies the return format ('numbered interactive list') and how to use the output ('Present these to the user so they can pick one by number'). This gives clear context for when to use this tool versus alternatives like 'get_dag_run_details' for deeper investigation.
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 are provided, so the description carries the full burden. It discloses key behavioral traits: it lists all buckets (implying a read-only operation), specifies the return format (creation date, sorted alphabetically), and includes a critical instruction about not guessing/defaulting the 'env' parameter. However, it doesn't mention potential rate limits, authentication needs, or error handling, leaving some gaps.
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 appropriately sized and front-loaded: it starts with the core purpose, follows with usage guidelines, then details parameters and returns. Every sentence adds value without waste, and the structure is clear and efficient for an AI agent to parse.
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?

Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: 'Get run statistics and trend analysis for a specific DAG.' It specifies the verb ('Get') and resource ('run statistics and trend analysis for a specific DAG'), and explicitly distinguishes it from the sibling tool 'list_dag_runs' by contrasting their outputs (analytics vs. flat list).
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 usage guidelines: 'Use this when the user asks about DAG reliability, performance trends, statistics, or historical patterns' with concrete examples. It also specifies when NOT to use it ('Unlike list_dag_runs...') and names the alternative tool, making it clear when to choose this tool over 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?
With no annotations provided, the description carries the full burden of behavioral disclosure. It effectively describes the tool's automated workflow (steps 1-6), including that it reads logs and extracts IDs, which clarifies its read-only, analytical nature. However, it lacks details on potential side effects, error handling, or performance characteristics like rate limits, leaving some behavioral aspects unclear.
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 efficiently structured with a clear purpose statement, a numbered list of automated steps, and separate sections for arguments and returns. Every sentence adds value, such as the sibling tool comparison and parameter warnings, with no redundant or verbose content, making it highly readable and informative.
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 complex diagnostic tool with 3 parameters, 0% schema coverage, no annotations, but an output schema, the description is complete. It covers the tool's purpose, usage guidelines, parameter semantics, and behavioral workflow. Since an output schema exists, it appropriately omits detailed return value explanations, focusing on the 'comprehensive failure report with root cause analysis.'
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?
Given 0% schema description coverage, the description fully compensates by explaining all three parameters: 'dag_id' is described with an example, 'env' specifies allowed values and critical usage instructions, and 'date' clarifies format and default behavior. This adds essential meaning beyond the bare schema, ensuring parameters are well-understood.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description explicitly states the tool's purpose as 'One-shot diagnosis of a failed DAG run' and details the six specific automated steps it performs. It clearly distinguishes this from sibling tools by noting it 'replaces the need to call 5-6 tools manually,' making its comprehensive diagnostic function distinct from simpler tools like get_dag_run_details or get_task_log.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides explicit guidance on when to use this tool versus alternatives: it should be used for comprehensive failure analysis instead of manually calling multiple tools. It also includes important usage constraints, such as the warning not to guess or default the 'env' parameter and to ask the user if unspecified, ensuring correct application.
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 provided, the description carries the full burden of behavioral disclosure. It effectively describes the tool's behavior: it returns formatted output with task states, durations, and try counts, includes hints for failed tasks, and provides a common DAG task flow for context. It also warns about the 'env' parameter requirement. However, it doesn't mention potential errors, 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured and appropriately sized. It starts with the core purpose, provides usage guidance, includes a practical example flow, details parameters clearly, and ends with return information. Every sentence adds value without redundancy, making it easy to parse and understand quickly.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (DAG run details with task instances), no annotations, and an output schema that likely handles return values, the description is complete. It covers purpose, usage, parameters, behavioral output, and integration hints (like get_task_log). The presence of an output schema means the description doesn't need to detail return structure, allowing it to focus on contextual guidance.
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 description adds significant meaning beyond the input schema, which has 0% description coverage. It explains 'dag_id' as 'The DAG identifier', 'dag_run_id' with format examples, and 'env' with allowed values and a critical warning about not guessing/defaulting. This fully compensates for the schema's lack of descriptions and provides essential context for proper usage.
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's purpose with specific verbs ('Get full details', 'see ALL tasks') and resources ('specific DAG run', 'every task instance'). It distinguishes from sibling tools like 'list_dag_runs' (which lists runs) and 'get_task_log' (which gets logs for specific tasks) by focusing on comprehensive run details with task statuses.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides explicit guidance on when to use this tool ('Use this to see ALL tasks in a DAG run with their pass/fail status') and includes practical context ('For any failed tasks, the output includes ready-to-use get_task_log() hints'). It also distinguishes from alternatives by emphasizing comprehensive details rather than just listing runs or getting specific logs.
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 provided, the description carries the full burden of behavioral disclosure. It effectively describes the tool's behavior: it's a read operation ('Get'), returns detailed DAG information ('source code / definition', 'details including file location, schedule, tags, and task list'), and has a critical constraint about the 'env' parameter requiring explicit user input. However, it doesn't mention potential errors (e.g., if DAG doesn't exist), rate limits, or authentication needs, leaving some gaps.
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 appropriately sized and front-loaded. The first sentence states the core purpose, followed by usage guidelines and parameter details in a structured 'Args:' section. Every sentence earns its place: the purpose, use cases, parameter explanations, and return value summary are all essential without redundancy. The formatting with bullet-like sections enhances readability.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's moderate complexity (2 parameters, no annotations, but with an output schema), the description is complete enough. It covers purpose, usage, parameters, and return values. Since an output schema exists, the description doesn't need to detail return values extensively, and it appropriately summarizes them ('Returns the DAG details including file location, schedule, tags, and task list'). This provides sufficient context for an agent to use the tool effectively.
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 description coverage is 0%, so the description must compensate fully. It does so by clearly explaining both parameters: 'dag_id: The DAG identifier' and 'env: Target environment — 'dev', 'uat', 'test', or 'prod'. IMPORTANT: Do NOT guess or default. Ask the user which environment if not specified.' This adds crucial meaning beyond the bare schema, including enum-like values for 'env' and a strict usage rule, making the parameters well-understood.
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's purpose: 'Get the source code / definition of a DAG' with specific verbs ('get', 'understand') and resources ('source code', 'definition', 'DAG'). It distinguishes from siblings like 'get_dag_run_details' or 'list_dags' by focusing on the DAG's source/definition rather than runs, status, or lists. The phrase 'Use this to understand what a DAG does' reinforces its unique role.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides explicit guidance on when to use this tool: 'Use this to understand what a DAG does — its tasks, operators, dependencies, schedule, and configuration. Useful for debugging or understanding a pipeline's structure.' It also includes a critical exclusion: 'IMPORTANT: Do NOT guess or default. Ask the user which environment if not specified.' This clearly defines the tool's context and constraints, helping the agent choose it over alternatives like 'list_dags' for structural insight.
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 are provided, so the description carries the full burden. It effectively discloses behavioral traits: it's a read-only operation (implied by 'Get detailed information'), it returns comprehensive details (state, config, resource usage, S3 log paths), and it provides hints for related tools. However, it doesn't mention potential errors, rate limits, or authentication requirements, which keeps it from a perfect score.
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

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. It fully documents all three parameters: application_id (with source guidance: 'from Airflow initialise task log'), job_run_id (with source: 'from Airflow processing task log'), and env (with enum values: 'dev', 'uat', 'test', or 'prod' and critical usage instructions). This adds significant 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 the tool's purpose: 'Get detailed information about a specific EMR Serverless job run.' It specifies the exact resource (EMR Serverless job run) and verb (get detailed information), distinguishing it from sibling tools like list_job_runs (which lists multiple runs) or get_emr_cost_summary (which focuses on costs).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides explicit guidance on when to use this tool: for detailed information about a specific job run, including config, resource usage, and logs. It distinguishes from alternatives by mentioning 'ready-to-use hints for read_spark_driver_log and browse_s3_logs,' implying those are separate tools for deeper log inspection. It also includes a critical exclusion: 'IMPORTANT: Do NOT guess or default. Ask the user which environment if not specified.'
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 provided, the description carries the full burden of behavioral disclosure. It effectively describes the tool's behavior: it's a read-only metadata operation (implied by 'without downloading'), it's performance-optimized ('fast'), and it returns specific metadata fields. However, it doesn't mention potential errors (e.g., if the object doesn't exist), authentication requirements, or rate limits, which would be helpful for a production S3 tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

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 fully compensate. It provides excellent parameter semantics: it explains 's3_uri' format with an example ('s3://bucket-name/path/to/file.csv'), defines 'env' as 'Target environment' with explicit valid values ('dev', 'uat', 'test', or 'prod'), and includes an IMPORTANT warning about not guessing/defaulting. This adds crucial context 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 specific action ('Get detailed metadata for a single S3 object without downloading it') and distinguishes it from sibling tools like 'read_s3_file' (which downloads content) and 'browse_s3' (which lists objects). It explicitly mentions the resource type (S3 object) and scope (single object metadata only).
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 with 'USE THIS TOOL when the user asks about a specific file's size, modification time, type, or other details.' It also distinguishes this from content-reading alternatives by stating 'This is fast because it only reads the metadata header, not the file content.' This gives clear when-to-use criteria and contrasts with sibling tools that handle content.
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 provided, the description carries the full burden of behavioral disclosure. It effectively describes the tool's behavior: it returns grouped items with specific fields (type, title, state, assigned person, effort/story points), shows grouping logic (by type with totals), and explains default behavior for omitted parameters. It doesn't mention rate limits or authentication requirements, but provides substantial operational 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?

This adds substantial 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 specific verb ('recursively list ALL files') and resource ('under an S3 bucket/prefix'), distinguishing it from siblings like 'browse_s3' (likely non-recursive) and 'list_s3_buckets' (lists buckets, not files). It explicitly mentions 'single call' to differentiate from paginated approaches.
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?

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 provided, the description carries the full burden of behavioral disclosure. It clearly indicates this is a state-changing operation (unpausing affects DAG scheduling) and specifies the return value ('confirmation of the unpause action'), though it doesn't detail error conditions or side effects like impact on existing runs.
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 efficiently structured with a clear purpose statement, parameter explanations in a labeled 'Args' section, and a returns statement. Every sentence adds value, with no wasted words, and important warnings are front-loaded with 'IMPORTANT'.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's moderate complexity (state change with environment targeting), no annotations, and the presence of an output schema (implied by 'Returns confirmation'), the description is complete. It covers purpose, parameters with constraints, usage warnings, and return value, leaving no gaps for the agent to operate effectively.
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 fully compensate. It provides essential semantic context for both parameters: 'dag_id' is explained as 'The DAG to unpause', and 'env' includes detailed constraints ('Target environment — 'dev', 'uat', 'test', or 'prod'') and critical usage warnings, adding 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 specific action ('unpause a DAG') and the effect ('allows scheduled runs to trigger again'), which distinguishes it from sibling tools like 'pause_dag'. It uses precise verb+resource language without being tautological.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides explicit guidance on when to use this tool (to resume scheduled DAG runs) and includes critical usage instructions for the 'env' parameter ('IMPORTANT: Do NOT guess or default. Ask the user which environment if not specified'), which helps differentiate it from alternatives and prevents misuse.
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 carries the full burden of behavioral disclosure and does so comprehensively. It explains state dependencies, the destructive nature of the operation ('permanently'), the two force modes with their different behaviors, the automatic stopping and job cancellation when force=True, and the step-by-step reporting of actions taken.
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 efficiently structured with a clear purpose statement upfront, followed by state requirements, force parameter behavior in bullet points, and organized parameter explanations. Every sentence adds value with no redundancy, and the formatting enhances readability without unnecessary verbosity.
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 destructive operation with 3 parameters, 0% schema coverage, and no annotations, the description provides complete context. It covers prerequisites, behavioral nuances, parameter semantics, and mentions the return format ('step-by-step report'). The presence of an output schema means the description doesn't need to detail return values further.
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 provides essential semantic context for all three parameters. It explains what application_id represents, the detailed behavior of the force parameter (including job cancellation implications), and the critical importance of the env parameter with specific valid values and guidance against guessing/defaulting.
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 specific action ('Delete an EMR Serverless application permanently') and distinguishes it from sibling tools like 'stop_emr_application' by emphasizing permanent deletion rather than temporary stopping. The verb+resource combination is precise and 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 guidance on when to use this tool versus alternatives: it specifies the application must be in STOPPED or CREATED state, mentions that 'stop_emr_application' could be used first if needed, and explains the force parameter behavior for handling running applications. It also includes important environment selection guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
