Create alert rule

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

Annotations confirm this is a non-read, non-destructive mutation (readOnlyHint=false, destructiveHint=false), so the description carries the burden. It does not state whether channels default to something, whether idempotency_key guarantees deduplication behavior, whether unmapped conditions silently ignore irrelevant parameters, or what the response contains. For a create operation with no output schema, this is thin behavioral disclosure.

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 single-sentence description is concise, but it is under-specified rather than efficiently specified. It provides a topical overview without the operational detail needed for a tool with 16 parameters and 10 condition enums. Conciseness is earned by packing the right info tightly, not by brevity alone.

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?

Given the tool's complexity (16 params, 10 condition_type enums, condition-specific parameter couplings) and low schema coverage (25%), the description should map conditions to their relevant optional parameters and explain cross-field dependencies. It does none of this. The absence of this mapping makes the tool hard to invoke correctly.

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 only 25% (most params are undocumented), and the description mentions only the four trigger categories. It does not explain which parameters apply to which condition_type (e.g., change_pct applies to change_pct condition, drop_positions to position_drop, competitor_domain to competitor_overtake, serp_feature to serp_feature), which is the essential semantic mapping for correctly invoking this tool. The description adds no parameter-level guidance beyond naming the trigger types.

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 states a clear verb+resource ('Create an alert rule') and enumerates the specific trigger categories: project rank changes, thresholds, SERP features, or competitors. This distinguishes it from sibling tools like create_webhook and create_signal. However, it doesn't name alternative events or clarify that these categories map to specific condition_type enum values.

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 vs update_alert_rule, list_alert_rules, or delete_alert_rule. The description doesn't specify prerequisites such as needing a valid project_id or recipient_ids configuration, nor does it clarify how condition_type interacts with the optional parameters. With 16 parameters and many sibling alert tools, the lack of selection context is a notable gap.

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