get_dag_run_status

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Description discloses that the tool returns state, execution date, and duration, which is beyond the input schema. This provides behavioral transparency for a simple read operation. No annotations to contradict.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Description is concise with a clear purpose statement followed by parameter and return information. Every sentence adds value. No fluff.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple read tool with one parameter, the description covers purpose, parameter, and return values. It lacks error handling context and usage guidelines, but given the simplicity it is reasonably complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The parameter dag_id is described as 'The DAG identifier.' This adds explanation beyond the schema's type and title. However, it lacks specifics like format, examples, or validation rules. With 0% schema coverage, the description provides minimal compensation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool gets the latest run status for a specific DAG. It is distinct from siblings like get_dag_runs_today which gets multiple runs, but does not explicitly contrast.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No usage guidelines provided. The description does not indicate when to use this tool over alternatives like check_failed_dags or get_dag_runs_today. An agent would need to infer from the tool name.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
