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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, closed-world), so the description's job is to add context — and it does: the async status-then-report behavior and the authentication requirement ('Needs the same API key'). It does not disclose how long results are retained or how an incomplete or failed job is represented, which would be the remaining useful detail.

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 front-loaded sentence that leads with status-then-report before listing payload fields. The trailing enumeration of report contents is long but each item is informative rather than filler; it could be trimmed slightly without loss.

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 single-parameter read tool with full schema coverage and annotations, the only real gap is the return shape — and the description enumerates severity, attack pattern, summary, patterns, indicators, MITRE techniques, remediation, and a report link. Nothing an agent needs in order to call it correctly 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 the single parameter is already described as 'The job id analyze_log_file returned.' The description reinforces the provenance of job_id but adds no format, validation, or error behavior beyond what the schema states, 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 and resource ('Returns the status and, once complete, the incident report of an analysis') and anchors it to the sibling that produces the input ('started with analyze_log_file'). It also enumerates the report payload, so an agent can tell it apart from analyze_log_file or scan_log_for_attacks without opening either schema.

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 precondition is explicit: this is the follow-up call for a job created by analyze_log_file, and the phrase 'once complete' signals it may return only status and must be re-called. It stops short of stating polling cadence, retry guidance, or what to do if the job failed or expired.

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