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

No annotations exist, so the description carries the full behavioral burden. It discloses one useful trait — that other fields are left untouched — but says nothing about permission requirements, whether the target status must already exist, whether transitions are validated or restricted, or any side effects (activity log, notifications).

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?

A single sentence that front-loads the usage cue and states the partial-update constraint without waste. It is efficient, though its brevity comes at the cost of the behavioral detail the tool lacks elsewhere.

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?

With three required parameters, no annotations, and no output schema, the description should explain valid status values, existence requirements, and side effects. Instead it provides one clause, leaving an agent unable to predict failure modes or return behavior for a mutation 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 description coverage is 100%, so all three parameters (task_number, board_id, status) are already documented in the schema. The description adds only the implicit notion that status is the sole mutated field; it contributes no format, validation, or lookup guidance beyond the schema.

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 gestures at a mutation of a task's status ("explicit status moves") but never names the resource or states a concrete verb like "set" or "transition". An agent must infer the target object from the tool name alone, and nothing separates it from update_task or move_task.

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?

"Use this for explicit status moves while keeping other fields unchanged" implies the selection condition (change only the status) but never names the competing siblings update_task or move_task, and gives no exclusions or prerequisites. Usage is inferable but not spelled out.

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