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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, covering the safety profile. The description adds useful behavioral detail about the output shape: ordered steps, section grouping, required count, run count, and the printable as_text variant. Error behavior is not covered, but the core behavior is transparent.

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?

Two sentences with no filler; the first describes the returned content and the second gives a practical parameter tip. It is appropriately sized and easy to scan, though a bit telegraphic.

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?

For a simple read-only two-parameter tool without an output schema, the description covers the main return content. It does not mention not-found behavior or what happens if a name is ambiguous, though the schema partially addresses name resolution. It is adequate but leaves some edge cases unstated.

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 both parameters. The description adds a small clarification about as_text producing a box against each step, but largely restates what the schema says. It does not add substantial meaning beyond the structured definitions.

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 that the tool returns one checklist with its ordered steps grouped by section, plus counts of required items and runs started. This is specific and distinguishes it from a plain list or creation tool, though it does not explicitly name checklist_list as the alternative.

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 usage for retrieving a single detailed checklist alert. It also gives a concrete parameter-usage tip for as_text. However, it does not explicitly say when not to use it or point to checklist_list for browsing all checklists, so guidance is only implicit.

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