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

With no annotations, the description carries the full burden, and it does disclose meaningful behavior: writes to a gitignored `.env` file and copies `main_character_photos` into `local_profile/references/`. It does not say whether omitted fields are preserved or overwritten, which is critical for a 14-parameter mutation where every field is optional.

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?

Front-loads the core action and persistence target, then adds the photo-copy side effect. Three compact sentences with no filler, though the second sentence is slightly convoluted.

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?

An output schema exists so return values need not be described, but for a 14-parameter configuration tool with zero annotation and zero schema-description coverage, the description omits the semantics of the vast majority of settings and their null-vs-omit behavior.

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% across 14 parameters, and the description mentions only `main_character_photos`, leaving 13 parameters (output dirs, publish URLs, art style, book mode, port, page count, character fields) undocumented. The description does not compensate for the coverage gap.

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+resource: 'Save or update user onboarding settings', which is clearly distinguishable from the read-side sibling get_onboarding_status. It does not, however, name any sibling explicitly to distinguish itself, so it falls short of a 5.

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 statement of when to call this versus get_onboarding_status or get_studio_profile, and no prerequisites. The implied use (configure the studio before generating books) must be inferred from the mention of 'future book'.

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