all the tools

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

With no annotations provided, the description carries the full burden and does so effectively by detailing behavioral traits: it explains the selection logic (status, dependencies, priority, creation time) and return behavior (full details or null). It does not mention side effects, permissions, or rate limits, but covers core operational behavior adequately for a read operation.

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 front-loaded with the core purpose in the first sentence, followed by detailed criteria in a logical flow. Each sentence adds essential information without redundancy, making it efficient and well-structured for quick understanding.

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 no annotations and no output schema, the description provides good contextual completeness by explaining the selection logic and return behavior. It could improve by specifying output format details or error handling, but it covers the essential operational context for a tool with one parameter and clear logic.

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%, with the parameter 'project_id' clearly documented in the schema as a UUID. The description adds no additional parameter semantics beyond implying project context, so it meets the baseline of 3 where the schema handles parameter documentation sufficiently.

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 specific action ('Identifies and returns the next actionable task') and resource ('within a specified project'), distinguishing it from siblings like listTasks or showTask by focusing on task selection logic rather than listing or displaying tasks. It explicitly defines 'actionable' with criteria, making the purpose distinct and well-defined.

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 implies usage by specifying criteria for task selection (status 'todo', dependencies 'done'), which helps determine when to use this tool for task prioritization. However, it does not explicitly state when to use alternatives like listTasks (for all tasks) or setTaskStatus (for updating tasks), missing explicit guidance on exclusions or comparisons with siblings.

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