Convert a Ruby hash to JSON

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

With no annotations provided, the description carries the full burden. It discloses key behaviors: sorting keys and rendering symbols as ':name' strings. However, it does not address error handling for invalid Ruby input or whether the output is a JSON string (vs. object), leaving gaps.

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?

Two concise sentences with no fluff. The description is front-loaded with the core action and includes relevant details about syntax and output formatting.

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?

For a tool with two well-documented parameters and no output schema, the description provides adequate context for basic usage. However, it lacks information about error behavior and output format specifics, which would be needed for complete understanding.

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 100%, so the description's value beyond the schema is limited. It adds a detail about symbol rendering but does not explain the effect of sort_keys beyond what the schema states. Baseline 3 is appropriate.

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 clearly states the tool's purpose: parsing a Ruby hash/array literal and returning clean JSON with sorted keys. It specifies supported syntax (hashrockets, symbol keys, shorthand, nesting, nil/true/false), making it distinct from the sibling tool ruby_hash_diff.

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?

The description implies usage (when you need Ruby-to-JSON conversion) but does not explicitly state when to use this tool versus alternatives like ruby_hash_diff. No exclusions or prerequisites are mentioned.

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