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

No annotations are provided, so the description carries full burden. It implies a mutation operation ('Update') but doesn't disclose behavioral traits like required permissions, whether changes are reversible, rate limits, or what happens to unspecified fields. The mention of updatable elements ('YAML, stages, jobs, etc.') adds some context, but critical mutation details are missing.

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

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

The description is brief and front-loaded with the core purpose. Both sentences are relevant: the first states what the tool does, and the second adds usage context. There's no wasted verbiage, though it could be slightly more structured for clarity.

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 mutation tool with 4 parameters, no annotations, and no output schema, the description is inadequate. It lacks details on behavioral implications (e.g., side effects, error handling), doesn't explain the return value, and provides minimal guidance on usage. Given the complexity and lack of structured data, it should do more to compensate.

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?

Schema description coverage is 100%, so the schema fully documents all 4 parameters. The description adds minimal value by implying 'content' relates to 'pipeline YAML' and 'name' is part of the update, but doesn't provide syntax, format, or constraints beyond what's in the schema. This meets the baseline for high schema coverage.

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 action ('Update'), resource ('an existing pipeline in Yunxiao'), and key updatable elements ('pipeline YAML, stages, jobs, etc.'). It distinguishes from sibling tools like 'create_pipeline_from_description' by specifying it's for existing pipelines, though it doesn't explicitly contrast with other update tools like 'update_application'.

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?

The description provides minimal guidance: it mentions 'Use this to update pipeline YAML, stages, jobs, etc.' but offers no context on when to choose this over alternatives like 'update_application' or 'update_app_orchestration', nor any prerequisites or constraints beyond needing an existing pipeline. No explicit when-not-to-use or comparison information is included.

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