rca_model_update_status

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

The description adds little beyond annotations: it states the action (advance model lifecycle) but does not explain idempotency, side effects, or validation of transitions. Annotations already mark idempotentHint=true and destructiveHint=false, so the description fails to provide extra behavioral context.

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

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

Extremely concise: two sentences plus Args/Returns. Every sentence adds value without redundancy. No unnecessary words.

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 update tool with an output schema, the description covers basic functionality but misses details: it does not explain constraints on status transitions, mentions of token/client_id are absent, and the lifecycle sequence is incomplete (deprecated/failed missing). Adequate but with gaps.

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 0% at the top level (the 'params' parameter has no description). The description lists two of the four nested fields (model_id, new_status) and explains the return type, partially compensating. However, it omits 'token' and 'client_id', and does not clarify the allowed status values beyond the sequence.

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 verb 'Advance' and the resource 'model through its lifecycle', specifying the status sequence. However, it implies forward-only progression (draft→trained→validated→deployed), while the schema allows setting to 'deprecated' or 'failed', which are not part of the listed sequence, causing slight ambiguity.

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 guidance on when to use this tool versus siblings like rca_model_create, rca_model_validate, or rca_model_delete. The description does not mention prerequisites, alternatives, or context for status updates.

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