set_log_level

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

With no annotations, the description carries the full burden and does add non-obvious behavior: it discloses that the change does not restart the TCP listener, which an agent could otherwise assume was required. It also reveals a parallel configuration path via the environment variable, useful operational context beyond the schema.

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?

Short and front-loaded, with the effect of each level stated before the tangential environment-variable and TCP-listener notes. The opening fragment 'Houdini Python-shell noise' is a little clipped but earns its place as scoping.

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. For a one-parameter toggle the description covers default, values, side effects, and an alternate control path, leaving little an agent needs missing.

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 schema only gives a bare string with default 'quiet', so the description is the sole source of meaning. It defines both valid values — quiet hides connect/execute/disconnect, verbose restores it — which is exactly what the schema omits, though it doesn't explicitly state that these are the only accepted values.

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 names the verb (set) and the resource (log level) and specifies exactly what the setting governs: per-command connect/execute/disconnect noise in the Houdini Python shell. It is clear what the tool does, though it never differentiates itself from siblings like get_last_log, leaving the distinction to be inferred.

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?

It tells the agent that quiet is the default and verbose restores the noise, and it notes the HOUDINIMCP_LOG=verbose environment-variable alternative. However, it never says when an agent should bother switching levels or when this is unnecessary, so usage is implied rather than guided.

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