discord_create_forum_post

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

Describes permissions and return values (name and thread ID). Annotations already indicate non-destructive creation; description adds value by detailing prerequisites and output, enhancing transparency beyond what annotations provide.

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?

Three sentences, each serving a distinct purpose: action definition, permissions, and alternative tool/output. No wasted words; front-loaded with essential information.

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?

With no output schema, description adequately notes returned fields (name, thread ID). Provides alternative tool and permission requirements. All necessary context for an agent to invoke correctly is present.

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?

All 4 parameters are fully described in the schema (100% coverage). Description adds guidance for the optional 'applied_tags' parameter, directing users to discord_get_forum_tags for valid IDs, which is useful beyond schema 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?

Description clearly states the verb 'create', the resource 'a new post (a thread with a starter message)', and the context 'in a forum channel'. It effectively distinguishes from siblings like discord_reply_to_forum and discord_create_thread.

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?

Explicitly lists required permissions (Send Messages, Create Public Threads) and directs users to discord_reply_to_forum for follow-up messages, providing clear guidance on when to use this tool vs an alternative. Lacks guidance on when not to use (e.g., for editing), but still strong.

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