d3p_pipeline_validate

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

With no annotations, the description must cover all behavioral traits. It discloses that the tool does not execute the pipeline, provides a cost estimate, and checks compatibility. However, it omits details about authentication needs, side effects (likely none), and output format, which are important for a validation tool.

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 long, front-loaded with the core purpose and behavior. Every word adds value, with no unnecessary elaboration.

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 low schema coverage (0%) and no annotations, the description should provide more context. It references the execute tool's format but does not describe the output (though an output schema exists, it is not explained). The tool's behavior is clear, but input requirements and return values are under-documented.

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 single parameter 'pipeline' has no schema description (0% coverage). The description only says 'Same input format as d3p_pipeline_execute', which is vague and does not explain the expected JSON structure, required fields, or constraints. The default '{}' is mentioned but not elaborated.

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 clearly states the tool performs a dry-run to check compatibility and cost estimation, avoiding actual execution. It explicitly distinguishes from d3p_pipeline_execute by contrasting dry-run vs. execution, making the purpose distinct.

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 description implicitly tells when to use (before executing) by stating 'without actually executing it' and references the alternative d3p_pipeline_execute. However, it does not provide explicit when-not-to-use scenarios or mention other sibling tools like d3p_pipeline_status, leaving some ambiguity.

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