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

No annotations provided. Description explains state mutation (creates in 'completed' status with timestamp) and side effects (visibility in queries), but lacks safety profile (reversibility, idempotency, destructive nature) and return value description (output schema is false).

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 core action (record completed task), followed by use cases, alternative comparison, and side effects. Every sentence earns its place.

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?

Comprehensive for usage intent and sibling differentiation. Missing explicit return value description (no output schema exists), though side effects are covered. Complete parameter documentation and clear behavioral scope for a logging tool.

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 coverage is 100% with clear descriptions for all 6 parameters. Tool description adds no parameter-specific semantics beyond schema, relying entirely on structured schema documentation. Baseline 3 appropriate for high-coverage schemas.

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 specificity: 'Record a task that is already completed' with mechanism 'creating it directly in completed status with an end timestamp.' Clearly distinguishes from siblings by contrasting with 'task_add followed by task_done' workflow.

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?

Explicit when-to-use: 'log work that was done outside the task system, or to record completed items retroactively.' Names alternative explicitly ('Unlike task_add followed by task_done') and notes outcome visibility ('appear in completed task queries and standups').

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