switch_session

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It does not state that this mutates global state (the active session), what happens to the previously active session, whether other session state is preserved, or whether the session_id must reference an existing/open session.

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?

A single short sentence with no wasted words and the action front-loaded. But the brevity reflects under-specification rather than efficient communication, so it lands at minimum-viable rather than strong.

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?

An output schema exists, so return values need not be explained, and the tool is low-complexity with one required param. Still, the description omits usage context and parameter meaning, leaving an agent to guess at the session lifecycle semantics.

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 0%, and the description adds nothing about session_id (its source, format, or validity). With only one parameter and no compensating detail, an agent cannot tell whether the ID comes from create_session, list_sessions, or elsewhere.

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?

States a specific verb ('switch') and resource ('session'), which is distinct from siblings like create_session, close_session, and list_sessions. However, it offers no differentiation statement or explanation of what 'switching' actually means operationally (active debugging 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 versus create_session, list_sessions, or close_session, and no prerequisites stated (e.g., whether the target session must already be open, or whether it requires an existing session context). The agent must infer everything from the name.

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