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

With no annotations, the description carries the full behavioral burden. "Retrieve" implies a read-only, non-destructive operation and the examples usefully sketch the return shape (board ID, name, privacy). However, it omits auth requirements, rate limits, and whether options are paginated — real gaps for a zero-annotation tool.

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?

A single tight sentence, front-loading the verb and resource with the examples as supporting detail. Nothing is wasted, though it is minimal enough that a little more context could fit without bloat.

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 one-required-parameter read tool with no output schema, the description partially compensates by naming returned fields. But it gives no usage context or auth notes, so an agent still lacks the framing needed to know when this call belongs in a workflow.

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 100%, and the schema already explains channel_id as a UUID sourced from reeling_list_channels and marks api_key optional. The description adds 'connected channel' framing but no syntax or format detail beyond the schema, so the baseline 3 applies.

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 pairs a specific verb ("Retrieve") with a specific resource ("publishing options for a connected channel") and disambiguates with concrete examples (Pinterest boards, TikTok creator configs). An agent can distinguish it from siblings like reeling_list_channels or reeling_publish_post. It stops short of explicitly naming a sibling it contrasts with, so it is not a 5.

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 when-to-use guidance, no prerequisites, and no alternatives mentioned. The agent must infer that this is a discovery call preceding publishing. The examples hint at purpose but don't route the agent between tools.

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