save_profile

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

No annotations are provided, so the description bears full responsibility. It only says 'Create or update' without disclosing mutation behavior, overwrite semantics, validation rules, or error handling. The agent cannot infer safety or side effects.

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 a single short sentence, which is concise but under-specified. It sacrifices clarity for brevity. Could be expanded to 2-3 sentences without losing conciseness.

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?

Given 12 parameters, no output schema, and no annotations, the description is drastically incomplete. It fails to explain return value (presumably the saved profile), error cases (e.g., missing profile_id for update), or important constraints. This is insufficient for effective agent use.

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?

With 0% schema description coverage, the description must clarify parameter meanings. It only states 'from flat MCP parameters' without explaining any parameter defaults, allowed values, or relationships (e.g., profile_id triggers update). Parameter names are somewhat self-explanatory but key details like language default 'en' are omitted.

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 'Create or update a profile from flat MCP parameters' clearly states the action (create/update) and resource (profile). It distinguishes from sibling tools like get_profile (read) and list_profiles (list). However, it could be more explicit about the update logic based on profile_id.

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?

No guidance on when to use this tool vs alternatives like update_preferences or get_profile. No mention of when to create vs update, which is critical given the 'create or update' nature. Agents need explicit prompts for conditional usage.

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