Create Channel

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

Annotations already declare destructiveHint=true and openWorldHint=true, so the safety profile is partly covered. The description adds genuinely new context — the admin role requirement — but says nothing about the fact that the channel will receive external Alertmanager/Slack traffic, that webhook URLs are secrets, or what the tool returns.

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?

Two compact sentences with the most decision-relevant information (the conditional field mapping) front-loaded and no filler. It is efficient, though concise at the cost of omitting the basic action verb.

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 destructive, open-world creation tool with five parameters, a nested object, and no output schema, the description is thin. It omits what a created channel contains, how credentials are stored, whether env/region scope the channel, and any return information an agent would need to confirm success.

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 20%, so the description must compensate; it does so usefully by stating the kind→field mapping (slack/webhook use url, pagerduty uses routingKey), which the schema only implies. However it leaves workspaceSlug, appSlug, env, and region entirely unexplained despite the nested requestBody structure.

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 never states that the tool creates a notification channel; it opens directly with conditional field requirements. The purpose is only inferable from the name/title and the channel-specific fields (url, routingKey), and it does not distinguish itself from siblings like updateChannel or testChannel.

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 guidance on when to call this versus updateChannel, testChannel, or deleteChannel, and no mention of prerequisites like an existing app/workspace scope. The only context offered is the admin-role requirement, which is an authorization constraint rather than usage routing.

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