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

No annotations provided, so description carries full burden. Discloses return value (UUID) and persistence model (stable numeric ID and UUID for cross-session references). Mentions task enters 'pending' state. Minor gap: doesn't mention error behavior (e.g., invalid depends UUIDs) or whether creation is atomic.

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?

Four sentences, zero waste. Front-loaded with purpose and return value. Validation rules in sentence two. Implementation details (stable IDs) in sentence three. Sibling differentiation in sentence four. Optimal information density.

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?

Strong coverage for 12-parameter tool with no output schema. Compensates for missing output schema by explicitly stating return value (UUID). Covers key behavioral aspects (pending state, stable IDs, recurrence requirements noted in schema). Minor gap: no mention of error conditions or blocking behavior when dependencies are unmet.

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 has 100% description coverage, establishing strong baseline. Description adds valuable high-level validation rule distinguishing required vs optional fields globally. Avoids redundant parameter documentation while providing syntactic context that complements schema details.

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?

Excellent purpose clarity. 'Create a new pending task and return its UUID' provides specific verb (Create), resource (task), and output (UUID). Explicitly mentions stable numeric ID/UUID for cross-session references, distinguishing persistence characteristics.

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?

Outstanding guidance. Explicitly states 'Only description is required; all other fields are optional' for validation context. Provides exact sibling alternatives: 'To record already-completed work, use task_log instead' and 'To copy an existing task, use task_duplicate' - clear when/when-not to use.

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