get_license_posture

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

Annotations already declare readOnly, idempotent, non-destructive, so safety burden is low. Description adds meaningful analytical context: it explicitly categorizes results into 'unlicensed', 'licensed but unconfigured', and 'licensed but unassessed', telling the agent these lead to different actions—genuinely useful beyond annotations. It doesn't mention data freshness or scope limits, keeping it below 5.

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?

Front-loaded with the core operation, then example questions, then a key distinction. Every line earns its place. The three-category distinction sentence is slightly dense but well-placed. Minimal waste.

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 no-param, read-only analytical tool with no output schema, the description gives enough to understand the return semantics (the three license posture categories) and scope. It could note result format or whether it covers all licensed products, but it is otherwise complete.

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?

Tool has zero parameters, so baseline is 4. Schema coverage is 100% but trivially empty; the description correctly implies a tenant-wide operation with no inputs.

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 analytical operation: crossing signed tenant licenses against actual usage of the security features they enable. This distinguishes it from sibling get_tenant_licenses (which presumably just lists licenses) by emphasizing the posture/usage-gap analysis. The example questions reinforce exactly what the tool answers.

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?

Provides clear example questions that define the usage context ('are we paying for unused features', 'do we have Entra ID P2 and is PIM used', 'how many licenses are idle'). It does not explicitly exclude alternatives or name sibling tools like get_tenant_licenses vs this one, but the examples narrow intent well.

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