verify_completion

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

No annotations provided, so description carries burden. Lists three checks but doesn't disclose whether the tool has side effects (likely read-only) or what happens on failure. Output schema exists but behavioral details are partially inferred.

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?

Well-structured with bullet points and usage note. Concise at ~50 words, though the phrase 'task_memo_add' could be clarified as a tool reference.

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 one parameter and existing output schema, description covers purpose, checks, and usage timing. Minor gap: no mention of return value or error handling, but partially mitigated by output schema.

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 param description 'Task ID to verify'. Description adds no additional semantics beyond what schema provides, so baseline score applies.

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?

Description clearly states the tool verifies task completion with specific checks, distinguishing it from sibling tools like task_status or task_memo_read which query but don't verify completeness.

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?

Explicitly states 'Use this after an agent reports completion' providing clear usage context. Could be improved by specifying when not to use (e.g., before completion) or mentioning alternatives.

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