pi_configure

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

With no annotations, the description carries the full behavioral burden. "Persist" hints at durable state change, but it does not say whether existing configuration is overwritten, whether the write persists across sessions, what permissions or prior state are needed, or what happens when several of the four fields are supplied at once.

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 filler, and the action verb leads. It is efficient, though its brevity is achieved partly by omitting necessary detail rather than by tight editing.

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?

A four-parameter write tool with zero annotation coverage, no output schema, and no required-field information needs more than one sentence. Missing are overwrite semantics, interaction between parameters, and confirmation of what persistence means operationally.

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%, so the description must compensate, and it partly does by naming the concepts behind most parameters (default model, default endpoint, named endpoint URL). However, it never clarifies the distinction between endpoint_name and base_url, nor whether default_endpoint and endpoint_name are mutually exclusive; the sentence attributes no meaning to base_url on its own.

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 pairs a specific verb ("Persist") with concrete resources (default model, default endpoint, named endpoint URL), so the agent knows this writes configuration. It never distinguishes the tool from setup-oriented siblings like pi_setup or pi_models, leaving ambiguity about which is the right entry point.

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 when-to-use guidance, no prerequisites such as requiring a prior setup call, and no stated alternatives. Only a weak implication exists that this is the tool for making a model or endpoint the default.

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