Start a queued printer job

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

Annotations already disclose destructiveHint=true, openWorldHint=true, and readOnlyHint=false, so the safety profile is covered. The description usefully adds that only a queued, confirmed, local job qualifies, but it omits the physical/irreversible nature of starting a print and what happens on failure.

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 with no filler; the operative verb and scope appear immediately. It is efficient, though its brevity leaves the gaps noted in other dimensions.

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 destructive, open-world mutation with no output schema and zero schema coverage, the description should explain the confirmation prerequisite, irreversibility, and failure behavior. None of that is present.

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 0% and neither parameter has any documented meaning. The description hints at 'confirmed' (confirmation_token) and 'queued job' (job_uuid) but gives no format, provenance, or single-use semantics, so it does not compensate for the coverage gap.

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?

Specific verb ('Commands ... to start printing') plus a tightly qualified resource ('one confirmed queued local printer job'). The qualifiers 'confirmed', 'queued', and 'local' meaningfully narrow the scope, though no sibling tool is named for contrast.

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 word 'confirmed' implies a prerequisite confirmation flow, which is consistent with the required confirmation_token, but the description never states that a confirmation must be created first nor routes the agent away from siblings like preflight_print_action or create_print_confirmation. Usage is only inferable.

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