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

Annotations (readOnlyHint=false, idempotentHint=false, destructiveHint=false) indicate a non-read, non-destructive, non-idempotent creation operation, and the description adds zero behavioral context beyond that. No mention of what gets created, side effects, authentication needs, or validation failures. The description carries none of the burden the annotations already partially cover.

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?

At one short line it is technically brief, but this is under-specification, not conciseness. There is no useful content to be concise about — the entire description is wasted on restating the HTTP method and path.

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 15-parameter tool with nested guardrails objects, multiple enums, and no output schema, a one-line REST stub is severely inadequate. An agent cannot determine required relationships (e.g., keyword needed when triggerEvent is comment), how guardrails behave, or what the API returns. This is far below minimal viability for this complexity.

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?

With 40% schema coverage and 15 parameters including nested objects, the description should compensate but says nothing about any parameter. The schema itself documents only a few fields (platform, workspace_id, keyword, platformAccountId); the many other parameters like guardrails, campaignDurationDays, and responseMode rely entirely on schema names and enums. The description adds no clarifying value.

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 is simply 'POST /inbox/automations' — a REST path stub that restates the tool name without stating what the tool does. It gives no indication of what an inbox automation is, what creating one accomplishes, or how it differs from the many sibling tools. The title 'Post Inbox Automations' in annotations adds little beyond the name.

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?

No guidance on when to use this tool versus alternatives. The schema hints at triggerEvent (comment vs dm) and responseMode (template vs ai), but the description never states the intended use case, prerequisites (e.g., needing a connected platform account), or when a sibling like aidelly_patch_inbox_automations_id would be more appropriate.

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