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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds only the filtering/chaining intent, contributing little behavioral context beyond the structured fields.

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 no filler, and the core purpose is front-loaded before the filtering hint. Efficient, though the brevity is partly what leaves usage gaps.

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 five-parameter, zero-required read tool with an output schema absent, the description is minimally adequate: it covers what the tool lists and how to filter. It omits return shape, pagination behavior (auto-fetch of all pages noted only in the schema), and relationship to adjacent tools.

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%, so baseline is 3. The description names two of the five parameters and frames them as ways to trace dependency chains, which adds mild interpretive value but no format, enum, or pagination detail 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 and resource ('List task dependencies'), so the agent knows exactly what the tool returns. It does not, however, distinguish itself from siblings like get_project_task_dependency or list_project_tasks, leaving the agent to infer the difference.

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 line 'Filter by task_id or depends_on_task_id to see dependency chains' implies the intended usage pattern, but there is no explicit when-to-use vs when-not guidance and no reference to alternative tools such as get_project_task_dependency for a single record.

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