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

Annotations already flag destructiveHint=true and openWorldHint=true, and the description adds real value: approving schedules content that 'will go out' (a consequential, hard-to-undo side effect) and requires the publish scope. It stops short of stating reversibility or bulk behavior across the ids array.

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 tight sentences with no padding: the consequence is front-loaded and the auth requirement follows. Nothing is wasted.

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 mutation tool with annotations covering the safety profile and no output schema, the description supplies the key missing pieces (effect, auth scope). Only reversibility and post-approval state are left 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?

Only one parameter with 100% schema description coverage ('Post ids to approve'), so the schema already carries the meaning. The description adds no format, limit, or selection guidance beyond that, making the baseline 3 appropriate.

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 the verb (approving) and the concrete effect (moves proposals to the schedule so they go out). The all-caps 'PUBLISHES CONTENT' opener is slightly ambiguous against the sibling posts_publish, but the scheduling detail differentiates it adequately.

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?

Gives one prerequisite ('Needs the publish scope') but does not say when to choose this over posts_publish or posts_dismiss, which are the obvious alternatives for acting on a post. Usage is implied rather than explicitly routed.

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