bale_connect_session

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

With no annotations provided, the description carries the full behavioral burden, and it does not say what happens to an already-active session on switch, whether this requires prior authentication, or whether any state is mutated or destroyed. Output schema exists so return values need less coverage, but the side-effect profile of a 'switch' operation is undisclosed.

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 front-loaded sentence with no padding; the core action and target are stated immediately. It is efficient, though the phone-number clause adds a small ambiguity rather than value.

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 one-parameter tool with an output schema, the description is roughly adequate but omits key operational context: whether a prior session is replaced, auth prerequisites, and how the session identifier maps to the parameter. The 'phone number' mention also introduces an unresolved gap versus the schema.

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 sole parameter is undocumented in the schema, so the description must compensate. It adds partial meaning by indicating the value may be a session name or phone number, but does not resolve the mismatch with the schema's 'Session Name' title or explain expected formats.

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 ('connect to or switch to') and resource ('a specific Bale user account'), which cleanly separates it from siblings like bale_list_sessions and bale_auth_request_code. However, it claims 'session name or phone number' while the schema exposes only a single 'session_name' string, so the stated input surface is slightly inconsistent with the actual tool.

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?

There is no explicit guidance on when to use this versus bale_list_sessions or the auth tools, nor any stated prerequisite (e.g., whether a session must already exist or whether auth is required first). 'Connect to or switch to' hints at the usage context but leaves the agent to infer it.

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