compare_todo_update

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

Annotations are absent, so the description must carry full burden. Only states it updates status; fails to disclose that it is a destructive write operation, idempotency, returned data, or required permissions. Minimal behavioral context.

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?

Extremely concise: a single sentence for purpose, followed by succinct argument descriptions. No unnecessary words. Front-loaded with the core action.

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 simplicity (update with two params) and presence of an output schema, the description covers the essentials. It specifies both parameters and allowed values. However, it omits edge cases, error handling, and confirmation that only status is updated (not other fields). Still, largely adequate for a straightforward mutation.

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 0%, and the description compensates by explaining both parameters: todo_id as the ID to update, and status with explicit allowed values ('pending', 'in_progress', 'done'). This adds useful meaning beyond the bare schema types. Could be slightly improved by noting that status is required or enumerating exact values.

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 'Update a todo's status' – a specific verb and resource. However, the tool name prefix 'compare_' is not explained and could cause confusion with sibling tools like 'compare_todos' (which likely lists). Despite this, the purpose is unambiguous for an AI agent.

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?

No guidance on when to use this tool versus alternatives such as 'compare_todos' or 'compare_status'. It lacks context about prerequisites or workflow integration, leaving the agent to infer usage from the name and sibling list.

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