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

Annotations already declare readOnlyHint=false, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds that this is a state transition into review and what follows it, but says nothing about stale expectedRevision failures, whether the submission can be withdrawn, or what a successful response contains.

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?

Three terse lines with the action first, then the condition, then the next step and a concrete example. Nothing is redundant and nothing needs to be read twice.

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 3-param mutation with full annotation coverage and no output schema, the description covers purpose, trigger, and successor step adequately. The main remaining gap is failure behavior around expectedRevision mismatches, which an agent would need to handle.

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 each parameter already documents its provenance (list_event_configurations, get_event_configuration). The worked example adds modest value by showing all three fields together and revealing the configurationId format prefix, though it does not explain the optimistic-concurrency role of expectedRevision.

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: sends a draft configuration version for review. The workflow position is clarified by naming approve_event_configuration as the next step, which implicitly separates it from approve/publish siblings, though it does not explicitly contrast with them.

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?

"Use when: a draft is ready to check" gives a clear triggering condition, and "Next: approve_event_configuration" routes the agent forward. There is no explicit statement of when NOT to use it (e.g., already-submitted or published configs), but the usage context is unambiguous.

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