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 usefully discloses the state transition (reverts to draft, will not fire) and the non-destructive nature, which is meaningful context. It still omits auth/permission needs, reversibility (can it be rescheduled?), idempotency, and error behavior for an already-published post.

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 short statements, front-loaded with the action and effect, with the non-destructive clarification placed last. No padding, though the second sentence is a fragment rather than fully integrated prose.

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 single-parameter tool with no output schema and no annotations, the description covers the essential outcome (draft revert, no deletion). It is borderline adequate but silent on return value, failure cases, and permission requirements that an agent may need before invoking.

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 the description never mentions the required 'id' parameter or what identifier it expects (post id vs. scheduled-job id). With one undocumented parameter, the description does not compensate for the schema gap, leaving semantics to inference.

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+resource (cancel a scheduled post) and adds the concrete effect: reverts to draft so it will not fire. It implicitly distinguishes itself from update_post and does not overlap with the read/result siblings, though it never explicitly names an 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?

Usage is implied by the effect description (use when a scheduled post should not fire) and by the 'does not delete' note, which steers away from destructive expectations. However there is no explicit when-to-use vs update_post, and no prerequisites or state conditions (e.g. post must be scheduled) are given.

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