Update channel

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

Discloses partial update behavior ('Only passed fields change'), special category semantics ('none' to remove), and dry_run support. Adds value beyond annotations which only indicate non-destructive mutation.

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?

Three concise sentences, front-loaded with the main action. No redundant or superfluous content.

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?

Adequately covers essential behavior given 8 parameters and no output schema. Missing mention of return values or error conditions, but overall sufficient for an edit 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?

Schema coverage is 38%, but description compensates by listing editable fields and explaining special values like 'none' for category and the dry_run boolean. Adds meaning beyond 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?

Clearly states the verb 'Edit', resource 'channel', and specific fields (name, topic, slowmode, NSFW, category). Distinguishes from sibling tools like create_channel or delete_channel.

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?

Implies usage for modifying existing channels, but does not explicitly state when to use vs alternatives like create_channel or clone_channel. No prerequisites or exclusions mentioned.

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