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

The description says 'Update', which conflicts with the destructiveHint=true annotation and the delete_finding name, and it does not disclose that a finding will be removed. It adds no operational context such as idempotency, retry behavior, or permission requirements. The description actively obscures the tool's destructive behavior rather than clarifying it.

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 short, but it is grammatically awkward and not front-loaded with the core action. The word 'Update' at the start undercuts the delete operation and makes the sentence misleading. This reads as under-specification rather than effective conciseness.

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 destructive, idempotent tool with 7 parameters and no output schema, the description leaves out required fields, deletion semantics, versioning behavior, and results. Even though annotations provide some safety signals, the description adds almost no contextual completeness. An agent cannot invoke this tool correctly based on the provided text.

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%, and the description does not explain any of the 7 parameters, including projectId, findingId, idempotencyKey, or expectedVersion. It only vaguely references 'project metadata' without mapping to any schema field. With no enums or parameter-level documentation, the agent is left to infer everything from parameter names.

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 uses 'Update' as the main verb while the tool is named delete_finding and requires a findingId, so it never plainly states that the tool deletes a finding. 'Hosted delete finding' is an unclear object phrase and does not distinguish this tool from update_finding or create_finding. This is misleading rather than informative.

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?

There is no when-to-use or when-not-to-use guidance, and no alternative tools such as update_finding or record_delete are mentioned. The vague phrase 'using privacy-filtered project metadata' does not constitute actionable usage guidance. An agent cannot determine when delete_finding should be selected over its siblings.

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