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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds meaningful context beyond them: results are ordered by date, the returned fields, and specifically that a Cotlet API key with app access is required.

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 scoping info is front-loaded and there is little waste, but the first two sentences are largely redundant (both say date range plus client/address/crew/price), which costs a bit of tightness.

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 read-only list tool with full schema coverage and annotations carrying the safety profile, the definition is nearly complete; it even compensates for the absent output schema by naming the returned fields. Only the lack of pagination-volume guidance keeps it from a 5.

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 the schema already documents from/to/crew/status and the status enum. The description only echoes the crew/status filters without adding syntax or format detail, so the baseline 3 applies.

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 (Lists) and resource (jobs/visits) with scope (date range) and returned fields (client, address, crew, price), so an agent can distinguish it from create_job, get_route, or the many sibling list tools. The only blemish is that the first two sentences restate the same idea, but the purpose is unmistakable.

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?

It says you can 'Filter by crew or by status' and that results feed reschedule_job or add_job_note, which implies intended usage, but it never states when to use this tool versus alternatives or any exclusion. Usage is inferable rather than explicit.

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