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

Annotations already disclose destructiveHint=true and idempotentHint=false, so the mutation profile is known. The description adds genuinely useful context beyond that: no change occurs until a human approves the exact request and execute_approved_action is called, plus the note that org-level MCP approval requirements are configurable while business workflow approvals always apply. This is valuable and consistent with the destructive annotation.

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 opens with boilerplate ('Use this when working with RetailHardHat field_operations records...') and buries the actual purpose in the second sentence. The approval-workflow sentences earn their place, but the lead-in wastes front-loaded space.

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?

An output schema exists, so return values need not be explained. The description adequately covers the approval gate, the trickiest behavioral aspect, but for a complex nested update payload with 0% param coverage it leaves the editable-field surface entirely undocumented, so the agent still cannot confidently construct the data object.

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 0%, and the data object contains eleven undocumented nested fields (title, trade, status, dueDate, severity, vendorId, etc.). The description says nothing about which fields are editable, valid status transitions, or format expectations, so it does not compensate for the coverage gap as required at low coverage.

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 clear verb+resource: 'Edit a punch-list item.' An agent can tell this is the update operation for punch items versus create/delete/get/list siblings. However, sibling differentiation is only implicit via the verb, and the odd phrase 'without verifier-identity overrides' muddies rather than sharpens purpose.

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 only usage trigger is boilerplate: 'Use this when working with RetailHardHat field_operations records in the connected organization.' There is no when-to-use versus alternatives (e.g., create_punch_item, delete_punch_item) and no explicit when-not guidance. The approval caveat is behavioral, not a usage-routing guideline.

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