json_del

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

No annotations are given, so the description must disclose all behavioral traits. It only states that deletion occurs and returns a success/error message, but does not clarify behavior for root path deletion (e.g., whether it deletes the entire key) or error handling for missing paths.

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 concise, using a single-purpose statement followed by clear argument definitions. It could be slightly improved by integrating the returns into the main sentence, but overall it is well-structured and quick to parse.

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 description covers the basic purpose, parameters, and return type. However, it lacks details on edge cases (e.g., deleting at root, non-existent path) and does not leverage the existing output schema to provide more comprehensive information. It is minimally adequate for a simple tool.

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 coverage, the description adds meaningful explanations for both parameters: 'name' is the Redis key, and 'path' is the JSON path with a default of '$'. This provides context beyond the schema's type definitions.

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 verb 'Delete', the resource 'JSON value', and the context 'from Redis at a given path'. This differentiates it from sibling tools like json_get (read) and json_set (write).

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 is provided on when to use this tool versus alternatives, such as using 'delete' for the whole key or 'hdel' for hash fields. The description does not mention when not to use it or any dependencies.

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