set_profile_parameter

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

With no annotations, the description must fully disclose behavior. It states 'Write' (mutation) and clarifies that None deletes the parameter. However, it does not mention potential side effects such as whether changes require a restart, whether invalid parameters are silently ignored, or whether the profile file is modified immediately. For a low-level config writer, this leaves gaps.

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 compact—two sentences of purpose/guidance followed by a concise Args list. Every sentence earns its place, with the purpose and usage guideline front-loaded. No redundancy or fluff.

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 tool with three required parameters and no output schema, the description covers what it does, when to use it, and the meaning of each argument, including the delete edge case. The only omission is a return value, but the tool likely returns nothing, so this is acceptable.

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?

The schema has zero description coverage, but the description compensates fully: category is exemplified with 'Output', name is scoped 'within that category', and value explains the None-to-delete semantics. This adds meaningful meaning beyond the raw schema.

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 opens with 'Write a raw parameter into the current profile's .ini configuration'—a specific verb, resource, and scope. It clearly distinguishes itself from sibling get_profile_parameter by being the write counterpart, and the 'advanced/low-level' tag further differentiates it from dedicated setter tools.

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?

Explicit guidance is provided: 'Advanced/low-level — prefer a dedicated request when one exists.' This tells the agent when to use this tool (as a fallback) and when to look for an alternative. It also implies the tool should not be used when a specialized setter is available.

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