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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the safety profile is covered. The description adds non-trivial context the annotations don't carry: execution is deferred pending human approval in Settings > MCP followed by execute_approved_action, and org admins can configure approval requirements. That is real behavioral value beyond structured data.

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?

Four short sentences, front-loaded with the action statement, then the approval caveat. The first clause about 'RetailHardHat field_operations records in the connected organization' is largely filler, but the remainder earns its place.

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 no explanation, and the approval gate is well described. However, for a destructive two-parameter mutation with zero parameter documentation, the description leaves the agent without enough to identify the target resource confidently.

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 both required parameters (dailyLogId, mediaId) have only UUID format/pattern constraints, no semantic description. The description never mentions either parameter, so an agent gets no guidance on which photo within which daily log is targeted — a meaningful gap for a destructive operation.

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?

States a specific verb and resource: 'Delete a daily-log photo.' An agent can distinguish this from delete_daily_log and the various delete_*_document siblings, though the differentiation comes from the resource name only rather than explicit sibling routing.

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 opening 'Use this when working with RetailHardHat field_operations records in the connected organization' is generic boilerplate rather than a real usage condition. The approval-workflow note ('no change occurs until a human approves... and execute_approved_action is called') does give meaningful context about the invocation path, but no alternatives or exclusions are named.

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