Pictory Projects

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

With no annotations provided, the description carries the full burden. It discloses useful behavioral traits such as 'auto-concurrency retry' and 'schema protection' for update_scene and indicates mutation via PUT/DELETE methods. But it does not explain side effects, reversibility, permission requirements, or synchronization/caching behavior in enough depth.

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 opening sentence gives an immediate summary, and the bulleted action list is compact with endpoints. Some statements are repetitive with the schema (e.g. list actions only restate endpoint names), and the tail becomes slightly garbled, but overall the structure is scannable and front-loaded.

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 multi-action dispatcher with 15 parameters, no annotations, and no schema field descriptions, the definition is incomplete. It never specifies which parameters apply to which actions, how payload should be structured for update actions, or the meaning of library, page/page_size, asset_id, file_path, and media_url. The output schema reduces the return-value burden, but invocation details remain under-specified.

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 description coverage is 0%, so the description must compensate for 15 parameters. It explicitly names only a few param-related concepts (project_id, template_id, text, duration, scenes, footage, thumbnail) and leaves payload, library, asset_id, file_path, media_url, page, page_size, and description undefined. It is insufficient for correctly constructing most invocation payloads.

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 that this tool manages Pictory projects and master video templates, and then lists every supported action with HTTP methods and endpoints. The resource scope (projects/templates) is distinct from the sibling tools (video, integrations, transcription, assets), so an agent can identify what it does without opening the schema.

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 provides clear action-level semantics (list, get, update, delete, create) and notes full web UI synchronization, which implies when the tool is relevant. However, it never explicitly tells the agent when to prefer this tool over a sibling or when not to use it, nor does it state prerequisites or exclusions beyond the action list.

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