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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered. The description adds no behavioral context beyond that — no note on default scope when unfiltered, result ordering, or that pagination is auto-completed (that detail lives only in the schema).

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 clauses with zero filler; the core action is front-loaded and the filter guidance follows immediately. Nothing needs trimming.

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 5-parameter, zero-required list tool with no output schema, the definition tells the agent what it returns (dependency records) but omits what happens when called with no filters, the shape of the chain results, and how it relates to the singular get tool. Adequate but with clear gaps.

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 every parameter is already documented in the schema and the baseline of 3 applies. The description restates task_id and depends_on_task_id with the added idea of dependency-chain traversal, which is a marginal, not substantial, gain.

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 states a specific verb and resource (list task dependencies) that an agent can map directly to the tool. It does not, however, differentiate itself from nearby siblings such as list_project_tasks or get_project_task_dependency, so the distinction rests on the name alone.

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?

It implies usage by naming the two filter parameters and the purpose of filtering ('to see dependency chains'), which tells the agent how to get a chain view. There is no explicit guidance on when this list tool is preferable to the singular get_project_task_dependency or to list_project_tasks.

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