star_job

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

With no annotations, the description carries the full behavioral burden, and it discloses almost nothing: no statement on permissions, idempotency (re-starring an already-starred job), or whether the change is reversible. 'Star or unstar' implies a toggling mutation, but the effect and safety profile are left unstated.

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?

One short, front-loaded sentence with no filler. It is efficient, though the brevity is partly a symptom of under-specification rather than deliberate 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?

The tool is simple: two fully documented required parameters and no output schema, so little is strictly needed. Still, for a mutation with zero annotation coverage, the description should say at minimum whether the operation is idempotent and what it affects, which is absent.

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% — both job_id and is_starred are documented directly in the schema, including the true/false semantics. The description adds no format or constraint details beyond that, 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 pair (star/unstar) and resource (a job), and the outcome (mark it as important). It is understandable on its own, but it does nothing to distinguish itself from related siblings such as save_job, update_job_status, or bulk_update_jobs, which is a missed opportunity given how many job-mutation tools exist.

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 guidance on when to use this rather than save_job or update_job_status, no prerequisites, and no note about whether starring is a persistent flag. The agent must infer all usage context from the name alone.

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