upload_to_supabase

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

No annotations are provided, so the description must carry the full burden. It mentions 'security validation' as a behavior but does not disclose what validation entails, whether the operation is idempotent, what permissions are required, or what side effects occur. This is a thin disclosure for a mutation tool.

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 a single sentence that is concise and front-loaded with the action. Every word adds value, stating the target (Supabase Storage) and a notable feature (security validation). There is no redundant information.

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?

The tool is complex with 6 parameters, 5 required, nested objects, and no output schema or annotations. The description provides no information about return values, error behavior, validation specifics, or usage context. It is inadequate for an agent to fully understand the tool's behavior and edge cases.

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?

With 100% schema description coverage, the baseline is 3. The description adds little beyond the schema, though 'analysis results' might loosely map to the metadata parameter. It does not clarify parameter syntax or relationships, but the schema already documents all fields thoroughly.

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 uploads images or analysis results to Supabase Storage, which is a specific verb and resource. While it doesn't explicitly differentiate from siblings (analyze_image, get_security_status), the upload action is unambiguously distinct from analysis or status retrieval.

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 is provided on when to use this tool versus alternatives. There is no mention of prerequisites, exclusions, or comparison with sibling tools. The intended use case is only implied by the action of uploading.

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