set_item_status

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

With no annotations provided, the description bears full responsibility for disclosing behavioral semantics. It states 'Change' implying mutation, but offers no details on reversibility, permission requirements, side effects, or whether the change is logged. The description adds minimal behavioral insight beyond what the tool name already implies.

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, front-loaded sentence that wastes no words. It immediately communicates the action and scope. Given that the schema and parameter names are self-explanatory, no additional structure or expansion is needed.

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?

The description only covers the most basic purpose. It omits usage guidelines, return behavior (no output schema), and how this tool fits alongside siblings like 'update_item'. For a simple mutation tool, more context about lifecycle and when to use this versus similar tools is expected.

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 baseline is 3. The description ('to open, in_progress, or done') echoes the schema's enum for 'status' but adds no new meaning about the parameter relationships, mandatory order, or semantics of the IDs. It is acceptable but provides no added value over schema documentation.

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 ('Change'), the resource ('punch list item status'), and the specific allowed values ('open, in_progress, or done'). This precisely defines the tool's function and distinguishes it from siblings like 'update_item' by focusing solely on status transitions.

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 provides no guidance on when to use this tool versus siblings like 'update_item' or 'flag_item'. It lacks prerequisites, context about the punch list workflow, or any mention of typical scenarios. The agent is left without decision criteria for selecting this tool over others.

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