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

Annotations already cover the safety profile (destructiveHint=true, idempotentHint=true, readOnlyHint=false), so the bar is lower. The description adds the auth requirement (project_tasks:write), which is genuine value, but says nothing about cascading effects on task dependencies or whether the deletion is recoverable.

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, with the action front-loaded before the scope requirement. No filler, nothing restated from the title.

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 single-entity delete with full annotation coverage and no output schema, the definition is adequate but incomplete: it omits what happens to related records (e.g., task dependencies) and whether the operation can be undone, which are the main things an agent would want before calling a destructive tool.

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% for the single id parameter (UUID format is fully specified in the schema). The phrase 'by ID' adds nothing beyond what the schema already documents, so the baseline of 3 applies.

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 task), and selection key (by ID), so the agent knows exactly what the tool does. It is distinguishable from siblings like delete_project_task_dependency by the resource name, though the description itself does not call out that distinction.

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 purpose implies usage (use it to remove a single project task), but there is no guidance on when to prefer it over update_project_task or how it relates to delete_project_task_dependency. No exclusions or preconditions beyond the scope note are provided.

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