agdp_create_offering

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

The description's 'Create' action directly contradicts the annotation readOnlyHint=true, which signals a read-only operation. This is a serious inconsistency. The API key note adds some context, but the contradiction invalidates the behavioral transparency.

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?

The description is two sentences, front-loaded with the primary action, and contains no extraneous words. The API key note is a necessary prerequisite and is placed efficiently.

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?

The tool is a simple create operation with a rich schema, but there is no output schema and the description does not clarify what happens on success or failure. The API key prerequisite is helpful, but the annotation contradiction and lack of return-value info leave significant gaps for an agent invoking this tool.

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?

The input schema covers all 4 parameters with descriptions, achieving 100% schema_description_coverage. The description itself adds no parameter-level detail, so the baseline score of 3 is 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?

The description states a specific action ('Create') and resource ('new offering on the aGDP marketplace'), making it clear what the tool does. It is distinct from the surrounding read-only market tools and from other agdp tools like agdp_get_offerings.

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?

The usage is implied by the verb 'Create', and the API key prerequisite plus registration link provide useful context. However, there is no explicit guidance on when to use this tool versus alternatives, nor any when-not-to-use clauses.

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