update_chat_channel

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

No annotations provided, so description carries full burden. It discloses that the tool mutates (update), supports partial updates (only provided fields change), and returns the updated channel. Lacks details on permissions or side effects, but adequate for an update 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?

Two efficient sentences; front-loaded with purpose and scope. No redundant information. Every word adds value.

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 tool with 7 parameters and no output schema, the description covers the essential operation, partial update behavior, return value, and example fields. Minor missing details like team_id fallback and error handling, but overall sufficient.

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 clear descriptions for each parameter (e.g., 'Omit to keep current'). The description adds the overarching concept of partial updates but does not significantly enhance individual parameter semantics beyond the 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?

Description clearly states the verb 'Update', the resource 'Chat channel', and the specific fields (name, description, topic, visibility, archived state). It distinguishes from sibling 'create_chat_channel' by specifying it's an update operation. The phrase 'Only the provided fields change' adds precision.

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 updating a chat channel's properties, with the note 'Only the provided fields change' guiding partial updates. No explicit when-not-to-use or alternatives, but sibling tools are for different entities, making the context clear.

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