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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered. The description adds useful context about what comes back ('sources, creators, license and price as stated'), but says nothing about pagination, limits, or behavior when a slug/job misses.

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?

Purpose is front-loaded in the opening clause, then the job taxonomy, then the three access modes, then the return fields — a logical progression. It is dense but every clause earns its place, with the only redundancy being the job list repeating the schema enum (offset by the parenthetical glosses).

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?

No output schema exists, and the description usefully names the return fields (sources, creators, license, price), so an agent knows what to expect. Combined with strong enum and annotation coverage the definition is largely self-sufficient; the missing limit/pagination semantics is the remaining gap.

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?

With 0% schema description coverage, the description carries the full param burden and largely does so: it explains job (curated list), query (free text, with two concrete example queries), and slug ('one item in full'). The limit parameter (default 8, max 25) is never mentioned, so one of four params remains undocumented in both schema and description.

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 a specific verb+resource — returns how-to workflows, tools and model guides for AI video — and enumerates the job taxonomy with human-readable glosses, so the agent knows exactly what content this surfaces. It does not, however, differentiate itself from near-siblings like get_guide or recommend_model, which likely overlap in scope.

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?

Gives clear mode-selection context: 'Pass job for a curated list, query for free text (e.g. "comfyui lipsync", "upscale to 4k"), or slug for one item in full.' That is concrete invocation guidance with examples. It stops short of stating when to prefer this tool over alternatives, and offers no exclusions.

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