convert_prompt_to_json

Convert any raw text prompt into a structured JSON object with extracted fields: purpose, goal, audience, context, tone, instructions, and format. Uses heuristic keyword extraction without requiring API keys.

Instructions

Convert a raw text prompt into a structured JSON prompt with extracted fields (purpose, goal, audience, context, tone, instructions, format)

Input Schema

promptYesThe raw text prompt to convert
Behavior2/5

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

No annotations are provided, so the description carries full burden. It only states the conversion function without disclosing behavioral traits such as how parsing is done (e.g., AI-based), whether it's deterministic, or any side effects. This is minimally transparent.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, front-loaded sentence of 18 words that efficiently conveys the tool's purpose without extraneous information. Every word is necessary.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity (one parameter, no output schema, no annotations), the description adequately covers the core functionality. It could mention potential limitations or error handling, but it is reasonably complete for a straightforward conversion task.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so baseline is 3. The description adds context about the output structure but does not add additional meaning to the single parameter beyond what the schema already provides ('The raw text prompt to convert').

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action (convert), input (raw text prompt), and output (structured JSON with listed fields). It distinguishes from the sibling tool 'edit_prompt_json' by specifying the transformation from raw text to structured format.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies when to use this tool (when you have a raw prompt to structure), but does not explicitly contrast with the sibling tool or state when not to use it. No alternatives or exclusions are mentioned.

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