get_monitor_sessions

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

With no annotations provided, the description carries the full burden. It indicates the tool is read-only and returns an array of identifiers, but does not disclose potential behavioral details like authentication requirements or session expiration handling. The description adds context on use cases but lacks explicit behavioral traits.

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 three sentences, front-loaded with the main purpose, followed by return value explanation and use cases. Every sentence adds value, with no wasted words.

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?

For a simple list tool with one optional parameter and no output schema, the description covers purpose, return value, and use cases adequately. However, it could mention that session-specific messages are obtained via get_monitor_session_messages to improve sibling differentiation.

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 coverage is 100% (one optional parameter, fully described in schema). The description only echoes that filtering by flow is optional, adding no extra meaning beyond what the schema provides.

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 lists chat session IDs, optionally filtered by flow. It uses a specific verb ('list') and resource ('chat session IDs'), and distinguishes from siblings like get_monitor_messages or get_monitor_session_messages by focusing on session identifiers.

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 mentions it is 'Essential for discovering active sessions, monitoring concurrent users, and analyzing session patterns,' providing clear context for when to use the tool. However, it does not explicitly state when not to use it or mention sibling alternatives.

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