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

Annotations already declare destructiveHint=true, idempotentHint=true, readOnlyHint=false, and openWorldHint=false, so the safety profile is covered. The description adds one genuinely non-annotated fact: the required project_documents:write scope. It says nothing about permanence, cascade effects on folders/links, or whether deletion is soft or hard.

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?

Two short sentences, action stated first, requirement second. No filler and nothing redundant.

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 single-parameter destructive tool whose annotations already declare destructiveness and idempotency, the description plus schema covers what an agent needs before calling. Minor gap: no note on irreversibility or what else is removed with the document.

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?

Single parameter with 100% schema description coverage; the schema already documents 'id' as the Project document ID. The description's 'by ID' mirrors that without adding format, lookup, or validation meaning beyond the schema.

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 ('Delete'), resource ('project document'), and identifier ('by ID'), so the action is unambiguous. It does not distinguish itself from other delete_* siblings such as delete_project_document_folder_template, but the resource name is precise enough to route correctly.

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 name and description — delete this specific document by its ID — but there is no explicit when-to-use guidance, no mention of alternatives (e.g., list_project_documents to find an ID, or update_project_document instead of deleting), and no stated preconditions.

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