publish_article

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

Annotations indicate write operation (readOnlyHint=false) and possible side effects (openWorldHint=true). Description adds that it publishes to timeline but doesn't detail irreversible behavior or required permissions. No contradiction with annotations.

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?

Single sentence, no filler, directly states action and resource. Appropriate length.

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?

Given simple tool with one param and annotations, description covers core purpose but lacks parameter details. With siblings create_article and unpublish_article, usage chain is understandable but parameter ambiguity reduces completeness.

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 has 0% description coverage for article_id. Description does not explain what article_id is or how to obtain it (e.g., from list_articles or create_article response). Fails to compensate for low schema coverage.

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?

Description clearly states verb 'Publish', resource 'existing draft Twitter/X article', and destination 'to the timeline'. Distinguishes from siblings like create_article (draft) and unpublish_article (reverse).

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?

Implies usage after creating a draft, but no explicit guidance on when not to use (e.g., if already published) or alternatives. Sibling list provides context but description does not specify prerequisites.

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