incident_edr_rule_exclusions__get_edr_rule_exclusion

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered. The description only restates the HTTP endpoint and adds no behavioral context such as what happens on an unknown UUID or whether a 404 is returned, so it contributes little beyond the structured data.

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?

Very short, but it says 'Get' twice and spends most of its words on the raw endpoint path rather than useful information. Nothing is front-loaded beyond the generic verb-resource phrase.

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 simple two-parameter read-only fetch with full schema coverage, rich safety annotations and no output schema, the definition contains enough for an agent to call it correctly. The lack of any return-shape or error-behavior note is a minor gap given the complexity level.

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%, including the exclusionUuid format/type note and the local 'fields' projection parameter, so the schema does the heavy lifting. The description adds no extra meaning beyond embedding the parameter name in the path template; 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 ('Get') and resource ('EDR rule exclusion') plus the concrete endpoint, so the agent knows this is a by-UUID detail fetch. It does not explicitly say how it differs from incident_edr_rule_exclusions__list_edr_rule_exclusions, though the singular resource and path parameter make the difference inferable.

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 when-to-use guidance, no when-not-to-use, and no mention of the list sibling as the alternative when an unknown exclusionUuid is not available. The agent must infer usage 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.
