create_slo

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

With no annotations, the description carries full burden for behavioral disclosure. It labels the operation as 'WRITE' but provides no details on idempotency, side effects (e.g., replacement vs creation on duplicate), required permissions, or rate limits. The brief statement is insufficient for an agent to gauge impact.

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 a single sentence, very concise. The '(WRITE)' is slightly redundant given the verb 'Create' but does not harm. No wasted words; it could marginally improve by integrating a usage pointer.

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 has one complex parameter (slo object) and no output schema. The description references an external spec, which is helpful but vague. It does not mention what the tool returns (e.g., created SLO ID) or error scenarios. Given the rich schema, it is minimally adequate.

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% with detailed descriptions for each property. The description only says 'Body fields per the SLO v1 spec (name, criteria, target, etc.)' – it adds no new meaning beyond what the schema already provides. Baseline 3 is appropriate.

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 clearly states the tool's purpose: 'Create an SLO (WRITE).' It uses specific verb ('Create') and resource ('SLO'), and the '(WRITE)' distinguishes it as a mutation. Among siblings (list_slos, get_slo, update_slo, delete_slo), this tool's role is unambiguous.

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 description mentions 'Body fields per the SLO v1 spec' but does not explicitly specify when to use this tool vs update_slo, nor does it mention prerequisites (e.g., need for an existing SLI definition). An agent would infer usage, but explicit guidance is missing.

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