loop_post

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

No annotations exist, so the description carries the full burden. It indicates a mutating action ('post') but fails to disclose side effects, permissions, rate limits, or the nature of the update being posted. This is minimal disclosure.

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?

Single sentence with no redundancy, but the brevity borders on under-specification. It is concise yet lacks any supporting context, so it is not well-structured for an agent to understand the tool's full scope.

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 simple tool with two fully documented parameters, the description covers the basic purpose. However, it does not explain what happens after posting, what constitutes a 'collection update', or any behavioral outcome. With no annotations or output schema, key aspects remain unaddressed.

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 100% with both parameters described ('Channel to post to', 'Collection ID'). The description adds context by framing the action as a 'collection update', linking the two params, but does not add format, syntax, or relationship details beyond what the schema already provides.

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 uses the specific verb 'Post' and identifies the resource as 'a collection update' to 'Loop'. It distinguishes from document/collection tools, but the phrase 'collection update' is somewhat ambiguous and does not clarify how it differs from sibling Loop tools like loop_channels or loop_commands.

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 usage guidance is provided. The description does not mention when to use this tool versus alternatives, nor any prerequisites, exclusions, or context. It simply states the action without any directive.

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