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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds one useful behavioral note - 'full inline detail', signaling it returns complete listings rather than references - but says nothing about pagination, posting counts, or filtering beyond the tenant.

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?

A single tight sentence that front-loads the provider and resource and ends with the scoping constraint and detail-level note. No wasted words.

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 one-parameter read tool with an output schema and full annotation coverage, the description carries enough to call it correctly: provider, resource, tenant scoping, and detail level. Only the when-to-use routing among sibling board tools is missing.

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 coverage is 100% and there is only one parameter, so the schema already documents the company subdomain fully. The description's 'for a tenant' corroborates the parameter's meaning but adds no syntax or format detail beyond it. 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 clear verb+resource+provider ('Pinpoint job board listing') and scopes it to a tenant, which distinguishes it from the many other jobs_*_board siblings by naming the provider explicitly. It stops short of contrasting itself with alternative job-board tools, but the resource and scope are unambiguous.

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?

Usage is only implied: an agent can infer this applies to Pinpoint-hosted tenants, but the description offers no when-to-use condition, no exclusions, and no pointer to sibling board tools for other ATS providers. Minimum-viable guidance.

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