get_session_details

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

With no annotations, the description carries the full burden for behavioral disclosure. It only states what the tool returns and does not mention read-only nature, permissions, error conditions, or output format, leaving an agent without critical safety and expectation details.

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?

The description is a single, front-loaded sentence with no redundancy. Every word adds meaning and the structure is optimal for quick scanning.

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?

The description is minimal and leaves the agent uncertain about the exact output and the optional profile parameter. No output schema or annotations exist to fill gaps, so the description should provide more detail about what 'per-channel statistics' includes.

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?

The description explains the session_db_id parameter's role, but it completely omits the profile parameter. With 0% schema description coverage, the description should compensate for both parameters, which it fails to do.

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 clearly states the tool returns per-channel statistics for a single session, identifying the session_db_id as the key. It is distinct from siblings like get_daily_summaries by scope, though it does not explicitly differentiate from get_statistics.

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?

The description implies usage when a session_db_id is known and channel-level detail is needed. It provides clear context but does not explicitly exclude alternatives or mention when to prefer this over other statistics tools.

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