read_channel_messages

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

No annotations provided, so the description must disclose behavioral traits. It only mentions pagination but omits details like read-only nature, rate limits, order of messages, or what happens when no messages match. Lacks sufficient transparency.

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 a single concise sentence, front-loading the key action and pagination feature. No wasted words, though additional detail could be incorporated without losing conciseness.

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 6 parameters, low schema coverage, no output schema, and no annotations, the description is too minimal. It does not explain return format, ordering, or behavior for empty results. Given the tool's complexity and lack of structured metadata, more details are needed.

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 17% (only guild_id has description). The description adds no parameter-specific meaning beyond mentioning before/after/around pagination. It does not explain limit, before_message_id, after_message_id, or around_message_id semantics, leaving the agent without sufficient guidance.

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 tool reads messages from a Discord channel and specifies the pagination options (before/after/around). This distinguishes it from sibling tools like search_guild_messages (searching) or get_message_context (single message context).

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 tool versus alternatives. The description only states functionality without indicating prerequisites, exclusions, or preferred scenarios.

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