settings_read

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

With no annotations, the description carries the full burden; it does disclose that the operation is a read and that a revision SHA256 accompanies the content, which is meaningful behavioral context. It omits path resolution rules (absolute vs. relative, allowed roots), behavior on missing/invalid JSON, and whether the SHA is computed over raw bytes or normalized content.

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?

One compact sentence that front-loads the verb and resource with zero filler. It is arguably too terse for a tool with an undocumented required parameter, but nothing is wasted.

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 existence of an output schema excuses it from explaining return values, and the SHA256 mention is a helpful bonus. However, for a file-reading tool with no annotations and a completely undocumented required path argument, the definition leaves real gaps an agent must guess at.

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% and the sole parameter 'path' is undocumented in both schema and description. The description does not say what root the path is relative to, which file types are accepted, or whether directories are rejected, so it fails to 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 ('Read') and resource ('JSON profile or Orca preferences file'), plus the notable return detail of a revision SHA256. This separates it from the write/compare/validate siblings, though it does not explicitly distinguish it from settings_catalog or profile_resolve, which also read settings-adjacent data.

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 use this instead of settings_catalog, profile_resolve, settings_compare, or host_preset_read, all of which appear in the sibling list. The only guidance is the implied 'read a file', which leaves the agent to infer selection among many overlapping read tools.

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