haops_get_dm_history

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

No annotations provided; description only states 'retrieve' and 'read', implying read-only. Does not disclose pagination behavior, ordering, or any side effects. Lacks depth for a mutation-free context.

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 sentences, front-loaded with purpose, zero wasted words. Highly concise and clear.

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?

Tool is simple; description covers core purpose. Missing details on pagination behavior and return format, but schema provides parameter info. Without output schema, description is nearly complete.

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?

Input schema covers 100% of parameters with descriptions. Description adds no extra meaning beyond schema. Baseline score for high coverage is 3.

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 verb 'retrieve', resource 'direct message history', and target 'with a specific user'. Distinguishes from siblings like haops_send_dm and haops_list_dm_conversations.

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 says 'Use this to read DM context before replying', providing a clear scenario. However, doesn't mention when not to use or alternatives.

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