List integrations

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

Adding the auth-requirement quirk, the misleading 'wrong api key' message, and the recommendation to call get_api_key_info gives valuable behavior beyond the readOnlyHint/idempotentHint annotations. The transparency is weakened by the garbled statement about addressing a check by uuid and list_checks' unique_key behavior, which appears to misattribute sibling-tool behavior to this endpoint.

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 first sentence is front-loaded and the auth warning is important, but the second paragraph is unnecessarily long and repetitive ('out of reach', 'nothing to pass', 'not a mistake to fix'). It could be cut to two or three tight sentences without losing value.

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 zero-parameter list operation with an output schema, the description covers purpose, creation path, auth prerequisite, failure mode, and remediation. It is nearly complete, but the confusing uuid/list_checks tangent reduces the agent's ability to trust and act on the guidance.

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?

The tool has zero parameters and 100% schema coverage, so the 0-param baseline of 4 applies. The description adds useful context by explaining the UUIDs returned are what create_check and update_check accept in their channels argument, even though it does not discuss tool parameters.

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 first sentence clearly states the tool lists the project's notification integrations and ties the output to the channels argument of create_check and update_check. However, the later paragraph says 'this tool ... addresses a check by uuid' even though list_integrations has zero parameters, which muddles the otherwise clear purpose.

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?

The description is explicit that a read-write API key is required, that read-only keys will fail with a misleading 401, and that get_api_key_info should be called to verify the key type. It also notes integrations cannot be created via the API. It does not clearly contrast with sibling list tools, and the uuid/list_checks aside introduces confusion about which tool the guidance applies to.

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