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

Annotations already indicate this is not read-only, not destructive, and idempotent; the description adds important behavior beyond that: merge versus overwrite semantics, USD conversion, post-save recommendation handling, and that scan schedules are not saved here. It also explicitly says no guardrail is changed and no money moves, with no contradiction.

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 core call condition is front-loaded, followed by tightly scoped bullets for replace behavior, currency conversion, post-save follow-up, and scan schedule handling. Despite its length, every section earns its place by preventing a likely invocation error or follow-through mistake.

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?

The tool has a complex nested profile schema and an output schema, and the description covers the important missing context: when to call, mutation semantics, currency conversion, post-save result handling, and the absence of a scan schedule field. An agent has enough information to invoke and follow through correctly.

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 coverage is 67%, and the description meaningfully supplements it by making `profile` and `skipped` mutually exclusive, clarifying `replace` merge behavior, specifying USD amounts and SOL conversion, and noting that scan schedule has no field here. These are operational details not fully captured by the schema alone.

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 and resource: save the user's interview answers or record that they skipped. The two call modes are clear, but it does not explicitly name sibling tools such as get_my_trading_profile or save_active_strategy, so sibling differentiation is implicit rather than stated.

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?

Gives exact timing and preconditions: call after playing answers back in TWO lines and the user says yes, or use `skipped: true` when they decline. It also states mutual exclusivity for `profile` vs `skipped` and explains `replace: false` for updates versus `replace: true` for overwrite.

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