save_profile_as

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

With no annotations, the description carries the full burden but omits key behavioral facts: the existence and default of the `overwrite` flag is never mentioned, nor is what happens when a profile of that name already exists. 'One per affected kind' is left unexplained, so the agent cannot predict the side effects of a save.

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 compact sentence with the action front-loaded and no filler. It is efficient, though the trailing clause 'inheriting the selected ones' is dense enough to blur meaning rather than sharpen it.

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 3-parameter mutation tool with 0% schema coverage, no annotations, and no output schema, the description is too thin. It neither documents the parameters nor explains the resulting profile set or the overwrite path, leaving the agent under-informed.

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, but it only alludes to `name` and vaguely to `keys` via 'inheriting the selected ones'. The `overwrite` parameter is never addressed, leaving a third of the inputs semantically undefined.

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 (save) and resource (user profiles), and clarifies the source is the session overrides rather than arbitrary data. It is reasonably distinguishable from siblings like import_profile_bundle or select_profiles, though it never names an alternative to disambiguate.

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?

Usage is only implied: the agent can infer it is for persisting current session overrides into named profiles. There is no explicit when-to-use, no prerequisites, and no comparison against profile-related siblings such as import_profile_bundle or list_compatible_profiles.

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