all the tools

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. While it mentions optional filtering and nested subtasks, it doesn't address important behavioral aspects like whether this is a read-only operation (implied by 'retrieves' but not explicit), pagination, rate limits, authentication requirements, or error conditions. The description adds some context but leaves significant gaps for a tool with no annotation coverage.

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 is appropriately concise with four sentences that each add value: stating the core purpose, two optional features, and the return type. It's front-loaded with the main functionality. There's no wasted text, though it could be slightly more structured with bullet points for the optional features.

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?

Given the tool's moderate complexity (filtering and nesting options), no annotations, and no output schema, the description is adequate but incomplete. It covers the basic functionality and parameters but lacks details on behavioral traits, error handling, and output format (beyond 'array of task objects'). For a tool with no structured safety or output information, more context would be helpful.

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 the schema already fully documents all three parameters. The description adds minimal value beyond the schema: it mentions 'optional filtering by task status' and 'option to include nested subtasks,' but these are already clear from the schema's enum values and parameter descriptions. The baseline of 3 is appropriate when the schema does the heavy lifting.

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 the tool's purpose: 'Retrieves a list of tasks for a specified project.' This is a specific verb ('retrieves') and resource ('tasks'), but it doesn't explicitly distinguish it from sibling tools like 'showTask' or 'getNextTask' which also retrieve task information. The description is clear but lacks sibling differentiation.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention sibling tools like 'showTask' (for single task details), 'getNextTask' (for prioritized retrieval), or 'expandTask' (which might handle subtasks differently). There's no context about prerequisites or when this tool is preferred over others.

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