Get a channel and its contents

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

There are no annotations, so the description carries the full burden of disclosure. 'Fetch' implies a read-only operation and 'a page of its blocks' signals pagination, but it does not explain error handling, rate limits, or what happens when the slug is not found. Some behavioral context is present, but it is incomplete.

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 a single, front-loaded sentence: 'Fetch a channel by slug with a page of its blocks.' Every word contributes meaning, and there is no redundancy.

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?

Given the lack of annotations and output schema, the description should provide more context about pagination behavior, return format, and possible errors. It only states the basic fetch operation, leaving significant gaps for an agent to understand the tool's full behavior.

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 schema has 0% description coverage. The description clarifies that 'slug' is the channel identifier and that pagination is involved, but it does not explain the 'per' parameter or the semantics of 'page' (e.g., indexing, defaults). It adds minimal meaning beyond the raw schema.

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 'Fetch' with the resource 'channel' and identifies it by 'slug', while adding 'with a page of its blocks' to clarify the scope. This clearly distinguishes it from sibling tools like arena_create_channel or arena_list_my_channels.

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 guidance is provided on when to use this tool versus alternatives. It does not mention that this is the read-by-slug option or that arena_list_my_channels might be used for listing channels without a slug. No exclusions or alternative conditions are stated.

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