Update Subtask Completion

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

No annotations are provided, so the description carries the full burden. It states the action but doesn't disclose any behavioral traits such as whether it's reversible, if it affects parent chore status, or any side effects. For a mutation tool, this is a significant gap.

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 a single, concise sentence that front-loads the purpose. No wasted words, and it's appropriately sized for a simple tool.

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, the description is mostly complete. However, with no annotations and an output schema present, the description doesn't explain what the response contains or any side effects. For a mutation tool, it could benefit from noting whether the update is idempotent or if it triggers any downstream effects.

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%, so the schema already documents all three parameters clearly. The description adds minimal value beyond the schema, but it does clarify the boolean semantics ('True to mark complete, False to mark incomplete') which is already in the schema. Baseline 3 is appropriate.

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 action ('Mark a subtask as complete or incomplete') and the resource ('within a chore'), which is specific and distinguishes it from sibling tools like complete_chore or update_chore. However, it doesn't explicitly differentiate from other subtask-related tools, but given the sibling list, it's clear enough.

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 when to use it (when updating subtask completion status) but doesn't provide explicit guidance on when not to use it or alternatives. It's adequate but lacks explicit exclusions or comparisons to similar tools like complete_chore.

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