create_feeds_collection_by_collection_id_open

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

Annotations already indicate idempotentHint=true and destructiveHint=false, but the description adds no behavioral context such as side effects, authorization needs, or what 'acting on collection open' entails. It does not contradict the annotations, but it also does not meaningfully extend them.

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 short and includes a structured Args section with little fluff. However, the opening phrase 'Create or act on collection open' is vague and does not earn its place as a clarifying statement.

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 description leaves the core semantics of the 'open' action unexplained and provides no usage context relative to sibling feed tools. The pointer to GET/schema helps with body discovery, but the overall operational picture is incomplete for an agent deciding whether and how to invoke this tool.

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 description identifies collection_id as a path parameter and body as the request payload, which adds modest context over the bare schema. The instruction to read the matching GET or /schema endpoint for expected fields is useful given that body is an open object with 0% schema description coverage, but it does not explain concrete parameter values.

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 says "Create or act on collection open," which is vague and largely restates the tool name without defining what 'open' means or what effect it has on the collection. The endpoint path clarifies the resource but does not explain the operation's purpose or distinguish it from sibling open/close feed tools.

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?

There is no guidance about when to use this tool versus alternatives such as create_feeds_by_id_close or create_feeds_item_by_item_id_open. The only operational advice is to read the matching GET or /schema endpoint first, which is a preparation step, not a selection criterion.

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