settings_compare

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

With no annotations, the description carries the full burden and only discloses the diff categories reported. It does not say whether the operation is read-only, whether paths must already exist, what happens on unreadable input, or how large diffs are handled — all material for an agent with no safety hints.

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 front-loaded sentence with zero filler. It is efficient, though the terseness is part of why the parameter and behavioral gaps remain.

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 output schema relieves the description of explaining return values, but for a two-required-parameter tool with 0% schema coverage and no annotations, the definition leaves the meaning of the inputs and the operational side effects unresolved.

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 and does not: it never explains what left_path and right_path point to (host files, workspace artifacts, or profile identifiers) or whether they must be pre-serialized. The only hint is the phrase 'serialized profiles'.

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?

Names a specific verb (compare) and resource (serialized profiles), plus the output shape (added/removed/changed keys). It is distinguishable from siblings like settings_read or settings_validate, though it never explicitly contrasts itself with them.

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?

There is no statement of when to use this versus settings_read, settings_validate, or profile_resolve, and no prerequisites or exclusions. The word 'exactly' hints at an exact-value comparison but never says what alternative comparison mode exists.

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