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

Annotations already declare destructiveHint=true and idempotentHint=true, so the safety profile is covered. The description adds only the vague phrase 'on your connected account'; it does not explain that setting saved=false removes an existing bookmark, what happens for nonexistent jobs, or any return behavior.

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 front-loaded sentence with no filler; the structure is efficient. It is arguably too terse for the behavioral burden, but the sentence itself 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?

For a two-parameter destructive mutation with no output schema and zero schema descriptions, the definition is under-specified. Annotations cover idempotency and destructiveness, but an agent still lacks guidance on auth requirements, invalid job_id handling, and the exact effect of saved=false.

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%, so the description must compensate, but it only loosely maps 'save or unsave' to the saved boolean and 'job' to job_id. It omits the integer/positive constraint on job_id and does not clarify the toggle semantics of the saved flag.

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 gives a verb (save/unsave) and resource (job) plus a weak scope note ('on your connected account'), but it essentially restates the tool name and title. It does not distinguish this mutation tool from the sibling read tool get_saved_jobs, leaving an agent to infer the difference from names alone.

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?

There is no explicit guidance on when to call this versus get_saved_jobs or save_search, and no mention of prerequisites such as needing an authenticated connected account. The only usage cue is the implicit 'save/unsave' toggle.

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