Validate QuokkaPix Video result manifest

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

With no annotations, the description must carry the full burden. It implies a read-only validation but does not explicitly state side effects, error behavior, permissions, or reversibility. The lack of any behavioral detail is a significant gap.

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 a single concise sentence with no filler. It front-loads the primary purpose, though brevity comes at the cost of omitted details.

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 has nested objects and three parameters but no output schema. The description fails to explain what 'browser QA' means, how the recipe is used, the role of recipeId, or what constitutes a successful validation. It is far from sufficient for an agent to call this correctly.

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 67% (recipe and manifest have descriptions, recipeId does not). The description adds no new meaning beyond the schema; it does not explain how recipeId relates to the recipe object or how the 'browser QA' maps to the manifest fields.

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 action (validate) and the target (quokkapix-video-result.json) against browser QA and an optional Video recipe. It distinguishes itself from generic validate_result_manifest by being video-specific, though 'browser QA' is ambiguous.

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?

No guidance is provided on when to use this tool versus its siblings like validate_result_manifest or validate_video_recipe. The description does not mention alternatives, prerequisites, or exclusions.

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