create_page_tool

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

Discloses authentication requirement and return type ('Creation result with page info'). However, lacks disclosure of error conditions (e.g., collision handling if page exists), idempotency, or permission requirements beyond basic auth. No annotations provided to supplement this.

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?

Front-loaded with purpose and auth requirement. Uses Args/Returns pseudo-structure which is readable but slightly awkward in a description field. No wasted words, though the Returns section is redundant given the presence of an output schema.

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?

Adequate for basic invocation given output schema exists—parameters are documented and return type is mentioned. However, fails to address error handling, collision behavior with existing pages, or relationship to the edit tool, leaving operational gaps.

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?

Compensates effectively for 0% schema description coverage by documenting all 3 parameters. Crucially specifies that content expects 'wikitext' format and that summary is an 'Edit summary' with a default value—semantic details not inferable from the schema alone.

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 specific verb (Create) and resource (wiki page). The phrase 'new wiki page' distinguishes from sibling edit_page_tool and delete_page_tool, though it could clarify the uniqueness constraint (what happens if page exists).

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?

Mentions 'Requires authentication' as a prerequisite, but provides no guidance on when to use this versus edit_page_tool, nor what happens if the page already exists. No alternatives or exclusions stated.

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