OfficialServer Quality Checklist
Latest release: v0.2.2
- Disambiguation5/5
Each tool targets a distinct aspect of Airflow (DAGs, runs, tasks, instances, logs, pools, variables, etc.), with clear descriptions that prevent confusion. Even similar tools like 'explore_dag' and 'get_dag_details' serve different granularity levels.
Naming Consistency4/5Most tools follow a verb_noun pattern (list_dags, get_dag_details, trigger_dag), but a few deviate (diagnose_dag_run, explore_dag, trigger_dag_and_wait). Overall, the pattern is clear and predictable.
Tool Count4/531 tools is high but appropriate for a comprehensive Airflow MCP server covering many subsystems. Each tool has a clear purpose, though some consolidation (e.g., get_dag_details and explore_dag) could reduce count slightly.
Completeness3/5The tool set is strong for monitoring and troubleshooting (DAGs, runs, tasks, logs, system health) but misses write operations for variables, connections, and pools. This leaves agents without the ability to create or update these resources.
Average 4.4/5 across 31 of 31 tools scored. Lowest: 3.8/5.

How is the quality score calculated?
The overall quality score combines two components: Tool Definition Quality (70%) and Server Coherence (30%).
Tool Definition Quality measures how well each tool describes itself to AI agents. Every tool is scored 1–5 across six dimensions: Purpose Clarity (25%), Usage Guidelines (20%), Behavioral Transparency (20%), Parameter Semantics (15%), Conciseness & Structure (10%), and Contextual Completeness (10%). The server-level definition quality score is calculated as 60% mean TDQS + 40% minimum TDQS, so a single poorly described tool pulls the score down.
Server Coherence evaluates how well the tools work together as a set, scoring four dimensions equally: Disambiguation (can agents tell tools apart?), Naming Consistency, Tool Count Appropriateness, and Completeness (are there gaps in the tool surface?).
Tiers are derived from the overall score: A (≥3.5), B (≥3.0), C (≥2.0), D (≥1.0), F (<1.0). B and above is considered passing.
Tool Scores
- Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so the description carries full burden. It does not disclose behavioral traits such as read-only nature, authentication requirements, rate limits, error handling, or potential side effects. Only describes what information is returned, not the behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is front-loaded with purpose and use cases, but it is somewhat lengthy with a detailed list of return fields. This could be streamlined since an output schema exists, but the structure is logical and easy to scan.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool is a simple getter with one parameter and has an output schema, the description covers usage scenarios, parameter meaning, and return fields adequately. It does not address edge cases or error conditions, but for a straightforward retrieval tool it is sufficiently complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 0% description coverage and only one parameter dag_id. The description adds a brief but clear explanation: 'dag_id: The ID of the DAG to get details for', which provides necessary context beyond the bare schema definition.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description explicitly states 'Get detailed information about a specific Apache Airflow DAG' and lists numerous specific user queries, clearly distinguishing it from sibling tools like list_dags (listing all DAGs) or get_dag_run (specific run details).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Provides a comprehensive list of when to use the tool with example user queries, but does not explicitly mention when not to use it or suggest alternatives. However, the extensive examples make the use context clear.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It correctly identifies this as a read operation (no mention of side effects) and describes the return fields. However, it does not disclose authorization requirements, error handling, or constraints like DAG existence, which would be helpful.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is somewhat verbose with bullet points and example queries. While helpful, it could be more concise. The front-loading of purpose is good, but the list of user queries takes up space that could be summarized more briefly.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the output schema exists, the description adequately covers return values (content, file_token). It addresses the parameter and usage examples. With many sibling tools, the context is fairly complete, though it could mention prerequisite conditions like DAG existence.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description fully defines the sole parameter 'dag_id' as 'The ID of the DAG to get source code for'. This adds necessary clarity beyond the schema's type-only definition.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'get' and resource 'source code for a specific Apache Airflow DAG'. It provides explicit example queries that distinguish it from siblings like 'get_dag_details' or 'explore_dag'.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description includes explicit 'when to use' scenarios with concrete user queries, making the tool's purpose clear. It lacks explicit 'when not to use' or alternative tool references, but the examples effectively guide usage.
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 must cover behavior. It states it returns warnings and lists the fields, but omits details like whether it is read-only, required permissions, or potential rate limits. The output schema reduces the burden slightly.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is fairly verbose with bullet-like examples and listing return fields. It could be more concise while maintaining clarity. The structure is functional but not optimized.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (no parameters, output schema exists), the description covers the output fields and use cases adequately. It could mention whether warnings are cumulative or from a specific time period.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has zero parameters with 100% coverage, so the description does not need to add parameter info. It correctly derives a baseline of 4.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it retrieves warnings and issues from DAG definitions. The usage examples explicitly list user queries that map to this tool, distinguishing it from siblings like list_dag_runs or list_import_errors.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides explicit when-to-use scenarios with natural language examples. However, it does not mention when not to use this tool or explicitly compare to alternatives like list_import_errors.
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 bears the full burden. It states the tool returns a list of tasks with fields like task_id, owner, etc., but does not disclose behavior on missing DAG, errors, or side effects. Adequate but not thorough.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with a clear opening, bullet-pointed examples, and return fields. It is slightly verbose but every sentence contributes value. Front-loaded with purpose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simple interface (one required parameter, list return), the description covers purpose, parameter, and return fields. There is an output schema, so return details need not be expanded. Minor missing error contexts but sufficient overall.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The only parameter dag_id is described as 'The ID of the DAG to list tasks for', adding meaning beyond the schema's type and required flag. With 0% schema description coverage, this explanation is valuable.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Get all tasks defined in a specific DAG' with a specific verb and resource. It distinguishes from siblings like get_task (single task) and explore_dag (different scope).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Provides explicit query examples such as 'What tasks are in DAG X?' and 'Show me the tasks in this workflow'. It does not explicitly state when not to use the tool, but the context is clear for its intended use.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so the description carries full burden. It explicitly states this is a write operation that modifies Airflow state by creating a new DAG run, and lists return fields. It does not detail permissions or side effects beyond creation, but is transparent enough for basic use.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with a clear action statement, example queries, notes, and return field list. It is slightly verbose but every section adds value. Front-loaded with core purpose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description is complete: it explains purpose, usage context, parameter meaning, return value fields, and behavioral notes. Despite the output schema existing but not provided here, the description's own return field list is thorough. For a moderately complex tool with 2 parameters and a clear action, this description fully covers the agent's needs.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, but the description compensates by explaining both parameters: dag_id as the DAG ID string and conf as an optional config dictionary with context explanation. This adds meaning beyond the raw schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it triggers a new DAG run and provides many example user queries. However, it does not differentiate from the sibling tool trigger_dag_and_wait, which slightly reduces clarity.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description lists explicit when-to-use scenarios with example user requests. It could be improved by noting when not to use this tool (e.g., if waiting for completion is desired, use trigger_dag_and_wait instead).
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. It describes the output structure and that it returns JSON, but does not mention authentication, permissions, or side effects. For a getter, it's adequate but not thorough.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has no parameters and is a simple health check, the description fully covers its behavior and return format. With the presence of an output schema (not shown but indicated), the description provides sufficient context for an agent to use the tool correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool has zero parameters, so schema coverage is 100% by default. The description adds value by enumerating the specific data categories returned, which goes beyond the empty schema. A score of 4 is appropriate for providing meaningful return context.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's function: getting overall Airflow system health, listing specific components (import errors, warnings, DAG stats). The purpose is distinct from sibling tools like list_import_errors or explore_dag, as it provides a consolidated view.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides explicit usage scenarios: when users ask about problems, for health checks, or starting investigations. It does not explicitly state when not to use it, but the context implies it's for high-level overviews, and alternatives like list_import_errors are more specific.
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 exist, so description carries full burden. It comprehensively lists all return fields (18 attributes) but does not mention error handling or permissions. Still, it transparently describes the tool's read-only behavior and output.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (2 params) and absent output schema, the description fully compensates by detailing all return fields. It covers the essential information needed for an agent to invoke and interpret results correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, so description must compensate. It provides brief explanations for dag_id and task_id ('The ID of the DAG containing the task', 'The ID of the task to get details for') but no additional details like formats, constraints, or examples. This is minimally adequate but not enriching.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool retrieves detailed information about a specific task definition in a DAG. It distinguishes itself from siblings like get_task_instance and get_task_logs by focusing on task definitions, aiding correct selection.

Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Provides explicit when-to-use guidance with example user queries. Lacks explicit when-not-to-use or alternative sibling names, but the examples sufficiently imply its scope.
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 the return fields (import_error_id, timestamp, filename, stack_trace) and explains the causes of import errors. It implies a read-only operation but does not discuss potential limitations like pagination or performance. Still, it is adequately transparent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is longer than necessary, with repeated information (e.g., causes of import errors are listed twice). The first sentence is clear, but the bulleted examples could be condensed. Some sentences do not add new value.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the low complexity (no parameters, output schema present), the description is fairly complete. It covers purpose, typical use cases, causes, and return fields. It does not mention behavior for empty results or error cases, but that is minor.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has zero parameters, so coverage is vacuously 100%. The description adds value by explaining the output fields beyond the schema, which is the only semantic context needed. Baseline is 3, but the extra output detail justifies a 4.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the purpose: 'Get import errors from DAG files that failed to parse or load.' It uses a specific verb-resource pair and distinguishes from sibling tools (none of which list import errors). The examples reinforce the specific resource.

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?
Despite no annotations, the description discloses the return fields (version, git_version) and explains its practical uses. It does not mention rate limits or permissions, but for a simple read operation with no side effects, the transparency about output and purpose is adequate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is verbose due to a long list of example user queries and repeating similar phrases. While structured with sections, it could be more concise without losing clarity. Every sentence adds some value, but some redundancy exists.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no parameters and an existing output schema, the description is fully complete: it explains what the tool returns, why it's useful, and when to invoke it. It covers all necessary aspects for an agent to correctly select and use this simple retrieval tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has zero parameters, so the description bears no burden to explain parameters. Instead, it adds value by describing the return structure and use cases, exceeding the baseline of 4 for tools without parameters.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it retrieves 'version information for the Airflow instance' and distinguishes itself from siblings like get_airflow_config and get_system_health. It provides specific examples of user queries that should trigger this tool, making its purpose unambiguous.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly lists when to use the tool (e.g., when user asks about Airflow version) and provides context for its utility (API compatibility, feature availability, troubleshooting). It lacks explicit 'when not to use' guidance, but given no overlapping sibling tools for version info, this is less critical.
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 must fully disclose behavior. It explains the return format (JSON with counts by state) and the optional filtering. However, it omits details like time range, whether it's real-time or historical, permission requirements, or any rate limits. The description is adequate but not exhaustive, scoring a 3.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured: a one-line summary, bullet-pointed use cases, a list of return states, and an Args/Returns section. It is comprehensive yet concise, with every sentence contributing value. No wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the output schema exists (though not shown) and the tool has only one optional parameter, the description covers purpose, usage, parameter, and return structure comprehensively. It leaves no obvious gaps for agent decision-making, earning a 5.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With schema description coverage at 0%, the description adds significant value by explaining the dag_ids parameter: it's optional, filters to specific DAGs, and defaults to all DAGs. This goes beyond the schema's simple type definition, earning a 4.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it gets statistics about DAG runs, specifying the verb 'Get' and the resource 'DAG runs' (aggregate stats). It effectively distinguishes from sibling tools like get_dag_details (single DAG) and get_dag_run (single run) by focusing on aggregate state counts. The use cases list further clarifies its role.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly lists example queries that should trigger this tool (health, success/failure counts, summary, etc.), providing clear context. It does not mention when NOT to use it or name alternatives directly, but the implied scope is clear given the sibling tools, so it's slightly below a 5.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description fully handles behavioral disclosure. Describes that it returns comprehensive metadata and lists fields. Implicitly indicates read-only operation. No contradictions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Well-structured with bullet points and clear sections. Front-loaded with purpose. Could be slightly more concise, but no unnecessary repetition.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given zero parameters and presence of an output schema, description sufficiently covers return structure and usage. Missing mention of potential limits or pagination, but not critical for a list-all tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Input schema has zero parameters, so description does not need to add parameter information. Baseline score of 4 is appropriate as no additional detail required.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states 'Get information about all Apache Airflow DAGs' and provides specific user queries that trigger this tool. It effectively distinguishes from sibling tools like get_dag_details (single DAG) and list_dag_runs (runs).

Usage Guidelines5/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Provides explicit when-to-use guidance with example user queries ('What triggered this DAG run?', 'Why did DAG X start running?'), making it easy for an agent to select this tool for traceability questions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It explains that events are produced when a task updates an asset/dataset and that they can trigger downstream DAGs. The return fields are listed. However, it does not disclose pagination behavior or any failure modes, which would be a minor improvement.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with sections for purpose, usage, return info, and args. It is slightly verbose but each sentence adds value. Could be tightened by merging the initial statement with the first usage line.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has 4 optional parameters and an output schema (described in words), the description covers all necessary details: purpose, use cases, return fields, and parameter semantics. It is complete for an AI agent to invoke correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Despite 0% schema description coverage, the description explains all four parameters in the 'Args' section with clear meanings (e.g., 'Filter events by the DAG that produced them'). The default for limit is also mentioned (100). This fully compensates for the missing schema descriptions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool lists asset/dataset events with optional filtering. It uses a specific verb-resource combination ('List asset/dataset events') and distinguishes itself from sibling tools by focusing on events from task updates and data-aware scheduling triggers.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides explicit usage scenarios starting with 'Use this tool when the user asks about:' and lists five concrete queries. This helps the agent understand when to invoke this tool versus others like get_upstream_asset_events or list_dags.
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, the description carries full burden. It comprehensively explains the tool's behavior, listing all return fields and the output format. It implicitly indicates a read-only operation with no side effects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured: a brief summary, usage examples, returned fields, args, and returns. It is front-loaded with the core purpose and remains concise without unnecessary detail.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (3 parameters, no nested objects) and the presence of an output schema (though not provided), the description covers all necessary context, including what the tool returns and how to use it.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema provides only types and 'required' but no descriptions (0% coverage). The description compensates by explaining each parameter and providing an example for dag_run_id, adding significant semantic value.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does 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 verb and resource: 'Get detailed information about a specific task instance execution.' It distinguishes from siblings like get_task (task definition) and get_task_logs by focusing on execution details.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides a bullet list of user queries that map to this tool, offering clear guidance on when to use it. However, it does not explicitly mention when not to use it or compare directly to sibling tools, which would improve clarity.
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?
No annotations are provided, but the description fully discloses that this is a read-only list operation. It describes the returned fields and their meanings, and implies no side effects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured: a summary line, usage examples, a brief explanation of the resource, and a clear list of return fields. Every sentence is informative and concise.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no parameters and an output schema present, the description provides sufficient detail about the return fields and overall purpose. It covers what an agent needs to know to use this tool correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
There are zero parameters, so the description cannot add parameter semantics. The baseline is 4 per guidelines, and the description does not need to elaborate further.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Get resource pools' and immediately lists example user questions. It is specific to listing all pools, which distinguishes it from get_pool (singular).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly lists when to use the tool with example questions. Also explains the concept of pools and their purpose, giving context for appropriate usage.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description fully carries the burden. It explicitly states 'This is a BLOCKING operation', describes internal steps (trigger, poll, return), default timeout, and details on failed tasks. No contradictions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with bullet points and clear sections. It is front-loaded with purpose. However, it is slightly verbose; some sentences could be combined. Still highly effective.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (blocking, polling, timeout, failure handling), the description is thorough. It explains the process, return fields, and even though an output schema exists, the description adds context. No gaps for an AI agent.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Despite 0% schema description coverage, the description adds rich meaning to all three parameters: `dag_id` with example, `conf` behavior description, and `timeout` default. This significantly aids an AI agent in understanding parameter usage beyond schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's action: 'Trigger a DAG run and wait for it to complete before returning.' It provides specific verb and resource, distinguishes from sibling `trigger_dag` by explicitly noting the blocking behavior, and includes example queries that match common user requests.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly lists example queries for when to use this tool and advises against it for long-running DAGs by suggesting `trigger_dag` and `get_dag_run` as alternatives. This clear when-to-use and when-not-to-use guidance is exemplary.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
