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

Beyond the annotations, the description discloses that create returns the new piece id in data and that bulk execution accepts piece_ids. It also transparently warns that update replaces workflowJson and checklistJson, though that behavior belongs to a sibling tool. No statement contradicts the annotations.

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 message is long and includes full update and checklist workflows that are irrelevant for a create-flattened tool, making it harder for an agent to extract the create-specific contract. The create details are front-loaded and organized, but the extra action modes should have been removed or replaced with pointers to sibling tools.

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?

For a write operation with no output schema and high parameter complexity, the description covers most of what an agent needs to call create correctly: required data fields, optional fields, return id, and where to find category/template IDs. It falls short on payload serialization, bulk semantics, and account parameter, and the embedded update/checklist text muddies the create scope.

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 does substantial work by enumerating required and optional fields inside data, the 255-character name limit, the exactly-one constraint, and categoriaIds as int[]. However, it does not explain that data is a string that must contain a serialized JSON payload, nor does it define account, piece_id, or piece_ids beyond a terse bulk note.

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 create action is clearly described: it creates a piece in the iClips catalog, requires name plus exactly one of basedOnTemplateId or workflowJson, and returns the new piece id in data. However, the opening sentence and action list also claim the tool updates pieces and marks checklist items, which are covered by sibling tools, so the purpose is not sharply differentiated for this create-specific variant.

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 gives strong operational guidance for the create path, including required data fields, the exactly-one constraint, and optional fields. It also points to iclips_workflow_templates and iclips_piece_categories for discovering valid IDs. It never states when-not-to-use this tool or routes update/checklist actions to their sibling tools; instead it documents those actions inline, which could mislead an agent.

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