runrunit_discord_create_channel

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

Reveals that the tool avoids duplicate channels by comparing names and uses an environment variable for guild ID. Lacks information on return values, failure modes, or permissions needed, relying solely on the description since no annotations are provided.

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?

Description is concise with three clear sentences, front-loading the main action. No superfluous information, but could be slightly more streamlined by merging the last two sentences.

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?

Covers the creation logic reasonably well given no output schema, but omits behavior when channel already exists (whether it errors or returns existing). Also no mention of permissions or error handling, leaving gaps for effective invocation.

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?

Adds meaningful context beyond the schema: explains the naming convention (slug-like) and that guild_id can be omitted if DISCORD_GUILD_ID is set. Schema already covers parameters, but description enriches the 'name' parameter example and the 'one channel per client' pattern.

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?

Clearly states it creates a text channel in a Discord server, with idempotency condition. However, it does not differentiate itself from the sibling tool runrunit_discord_get_or_create_channel, which likely has similar functionality.

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?

Implies usage for creating a channel per client pattern, but does not explicitly state when to use this over alternatives like get_or_create_channel. No exclusion criteria mentioned.

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