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

Annotations supply the safety profile (destructive, idempotent, open-world), and the description adds real blast-radius detail: existing orders are untouched, no money moves, and the effect on the public event page. Missing auth/permission requirements and any hint at the response, so not a 5. 'Idempotent' merely repeats idempotentHint.

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?

Four tight sentences, mutation mode front-loaded, no filler. The endpoint path (POST /events/togglesales) is the only marginally expendable element.

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 two-parameter toggle with full schema coverage and annotations, the description covers what changes, what is unaffected, and reversibility. It omits the return payload (no output schema exists) and any permission/credential context, which leaves a small gap.

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 coverage is 100%, so baseline is 3, but the description goes beyond the schema's terse value mapping by explaining the observable consequence of each flag (sales stop vs. sales resume). It does not describe event_id semantics, which the schema already covers.

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?

States a specific verb pair (publish/unpublish) plus the exact resource and scope ('ticket sales of one event'), and prefixes it with 'WRITE:' so mutating intent is unambiguous. Siblings are all read/get/list tools, so this one is immediately distinguishable.

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?

Explicitly explains the two modes: unpublishing stops attendees from buying on the event page, publishing starts public sales again, giving clear when-to-use context for each status value. It does not name exclusions or alternatives, though no sibling performs anything comparable.

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