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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered by structured data. The description adds the underlying endpoint (GET /molpro/jobs/info/{id}) and the shape of what comes back, but says nothing about auth requirements, error behavior for unknown job ids, or scoping to the caller's account.

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?

Two compact sentences, front-loaded with the substantive return-content list followed by the endpoint. No filler or redundancy.

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?

With no output schema present, listing the returned field groups is exactly the right compensation and covers most of what an agent needs. Minor gap: no indication of how a nonexistent or unauthorized job id is reported.

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?

There is a single parameter and the schema documents it fully ('Click2Mail job id.', integer, >0), so coverage is 100% and the schema carries the meaning. The description never mentions job_id, so it adds nothing beyond the schema — the baseline 3 for high schema 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?

Names a specific verb-resource pair (get full job details) and enumerates what 'details' covers — print options, document, address list, dates, cost, payment — which lets an agent distinguish it from the narrower siblings get_job_status, get_job_cost and get_job_tracking. It stops short of explicitly stating that routing relationship, so not a 5.

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 field list implies this is the comprehensive per-job read, versus the single-aspect siblings, but there is no explicit 'use this when...' or 'use X instead for...' clause. The agent has to infer the choice from content coverage alone.

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