analyze_reliability

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

With no annotations provided, the description carries the behavioral burden well: it discloses the scoring approach, output categories, ranked remediation actions, lack of model/log parsing/root-cause inference, and per-call cost. It stops short of explicitly stating side effects, data retention, or authorization requirements, but the analysis-only framing is clear.

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?

The description is dense but well structured: it front-loads purpose and scope, then summarizes outputs, usage cases, analytical limitations, and cost. Every sentence contributes useful selection or invocation context without filler.

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?

Given no output schema and no annotations, the description provides enough context for an agent to call this correctly: input scope, returned analytical categories, deterministic methodology, limitations, and cost are all stated. It is complete for the complexity of a read-only analysis tool.

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 100%, so the nested task fields are already well documented. The description reinforces the 25-task limit and per-call pricing, but those details are also present in the schema, so it does not add substantial parameter meaning beyond structured fields.

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 states a specific verb and resource: reliability analysis for recurring tasks, jobs, pipelines, or scheduled workflows. It also defines the output shape and explicitly contrasts itself with model-based inference, log parsing, and root-cause analysis, which helps distinguish it from siblings such as analyze_behaviour and extract_insights.

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?

It gives clear use cases: cron and pipeline monitoring, flaky-job triage, SLA and uptime adherence, agent task reliability, and prioritization. It also clarifies what the tool does not do, but it does not explicitly name sibling alternatives or state when not to use it.

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