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

Annotations already declare openWorldHint=true, idempotentHint=true, destructiveHint=false, so the public and repeat-safe nature is partly covered. The description adds that the story must be owned by the connected account, which is useful authorization context, but says nothing about reversibility, visibility latency, or what happens on republishing an already-public story.

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 action, the ownership precondition, and the destination are all in the first clause. Nothing can be trimmed without losing information.

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, no-output-schema mutation that publishes to a public library, the description covers the core action but omits the consent gate mechanics and reversibility. Annotations carry the safety profile, so the gap is moderate rather than critical.

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 only 50%: confirmPublicPublishing is documented in the schema, but storyId carries no description there or here. The description does not compensate for that gap by clarifying that storyId refers to an owned story, nor does it explain the confirmation semantics beyond the schema's own text.

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 (publish) and resource (a story) plus the scope constraints: it must be owned by the connected account and it lands in the public Story World library. That is enough to distinguish it from create_story or rename_story, though it never names its inverse sibling remove_story_from_world.

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?

There is no when-to-use or when-not-to-use guidance. The description gives no prerequisites, no mention of the confirmPublicPublishing consent gate, and no pointer to remove_story_from_world as the undo path, leaving the agent to infer the trigger conditions.

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