Compute Services Describe Streamlit

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

Annotations already declare readOnly, idempotent, non-destructive, open-world behavior, so the safety profile is covered. The description usefully enumerates the returned attributes, but adds nothing about permissions needed, error behavior for missing Streamlit objects, or visibility scoping.

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?

A single tight sentence that front-loads the verb and the key return attributes with zero filler. Nothing wasted and nothing ambiguous in structure.

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?

An output schema exists and annotations cover the safety profile, so the description needn't explain return formatting. It names the three described attributes, which is sufficient for this simple read tool; minor gaps (error/not-found behavior) keep it from a 5.

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%, including the anyOf/default handling for database and schema_name, so the baseline of 3 applies. The description does not mention the parameters at all, adding no meaning beyond the schema's naming and quoting guidance.

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?

States a specific verb (describe) and resource (Streamlit application) plus the exact fields returned: root location, stage, and query warehouse. It is clear what the tool does, though it does not explicitly contrast itself with siblings like compute_services_list_streamlits.

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?

Usage is implied by the 'describe' naming and the list/describe pair in siblings, but the description never states when to use this versus compute_services_list_streamlits or what prerequisites exist. Adequate but leaves selection to inference.

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