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

The description essentially restates the mutating nature already encoded by readOnlyHint=false. It does not disclose what happens to existing guidance, whether the referenced clarity process must already exist, or any side effects. Annotations provide some baseline, but the description adds little 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, front-loaded sentence with no filler. Every word contributes to identifying the action and target resource.

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 simple two-parameter tool with detailed schema descriptions and annotations, this is minimally viable. However, it lacks sibling differentiation and any note about replacement semantics or error conditions, so it is not fully complete.

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%, so both id and content are already documented structurally. The description's 'automation guidance message' and 'clarity process' language aligns with the parameters but adds no additional semantic detail 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?

The description states a specific action, 'Update', a specific resource, 'automation guidance message', and scopes it to 'a clarity process'. This distinguishes it from generic process-update tools, though it does not explicitly differentiate it from createClarityGuidance or updateAutomation.

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 guidance on when to use this tool versus alternatives like createClarityGuidance, updateClarityProcess, or updateAutomation. The usage context is only implied by the verb 'Update' and the parameter descriptions, with no explicit when-to-use or when-not-to-use guidance.

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