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

With no annotations provided, the description carries the full burden of behavioral disclosure. While 'Update' implies a mutation operation, the description doesn't specify what permissions are required, whether changes are reversible, what happens when optional parameters are omitted, or what the typical response looks like. For a mutation tool with 8 parameters and no annotation coverage, this represents a significant gap in behavioral context.

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, efficient sentence that immediately communicates the tool's purpose with relevant examples. There's no wasted language or redundant information. It's appropriately sized for a tool with comprehensive schema documentation.

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 mutation tool with 8 parameters, no annotations, and no output schema, the description is insufficient. It doesn't address critical behavioral aspects like required permissions, error conditions, response format, or side effects. While the schema covers parameter details, the description fails to provide the broader operational context needed for safe and effective tool invocation.

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 description coverage is 100%, so all parameters are documented in the input schema. The description adds marginal value by listing examples of updatable properties (name, description, password, talk power, limits, etc.), which helps the agent understand the scope of what can be modified. However, it doesn't provide additional semantic context beyond what's already in the schema descriptions.

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 clearly states the action ('Update') and resource ('channel properties') with specific examples of what can be updated (name, description, password, talk power, limits, etc.). It distinguishes itself from sibling tools like 'create_channel' and 'delete_channel' by focusing on modification rather than creation or deletion. However, it doesn't explicitly differentiate from 'set_channel_talk_power' which appears to be a more specialized version of this tool.

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?

The description provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (like needing channel_id), when not to use it, or how it differs from similar tools like 'set_channel_talk_power' or 'manage_channel_permissions'. The agent must infer usage from the tool name and parameter list alone.

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