Delete A Time And Material Attachment

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

Annotations already declare destructiveHint: true, so the description's emphasis on 'cannot be undone' is consistent and adds no new behavioral insight beyond confirming irreversibility. No additional traits (e.g., side effects, auth requirements) are disclosed, but the annotations carry the transparency burden.

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 contains some redundancy, repeating 'This cannot be undone' and 'Permanently removes' in nearly identical phrases. It includes useful endpoint and API area details, but the repetition reduces conciseness. Front-loads purpose adequately.

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 delete operation with no output schema, the description is moderately complete. It identifies required parameters and confirms irreversibility. However, it does not mention the expected response (e.g., 200 OK or no content), which could help an agent verify success. Annotations partially compensate by indicating destructive behavior.

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?

The input schema has 100% coverage with clear descriptions for both parameters (project_id and id). The description merely lists these required parameters without adding new meaning beyond what the schema already provides, so the baseline 3 is appropriate.

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 it deletes a Time and Material Attachment from a Project and emphasizes permanence. The verb 'deleting' and resource 'attachment' are specific. However, it does not differentiate from the sibling 'bulk_delete_time_and_material_attachments', leaving ambiguity about whether this handles single vs bulk deletion.

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 tells the agent to use this for permanently deleting Field Productivity records and lists required parameters, but it does not explicitly say when to use this tool versus alternatives like bulk_delete or other deletion methods. No exclusions or conditional usage guidance is provided.

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