Prompt Task Match Calculator

Enter your prompt and task

Prompt

Tip: include role, context, steps, and output format.

Task description

Describe the goal, constraints, and evaluation rules.

Task type

Output format

Tone

Required elements

Role

Context

Steps

Examples

Constraints

Evaluation criteria

Output instruction

These flags drive the structure and requirements scoring.

Keywords

Domain keywords (comma-separated) Forbidden keywords (comma-separated)

Domain terms can boost alignment; forbidden terms reduce the score.

Weights

Weights are normalized automatically.

Similarity

00.351

Coverage

00.251

Structure

00.201

Requirements

00.201

Example data table

Task type	Task description	Prompt snippet	Typical score range
Extraction	Extract entities into JSON with fixed keys.	Act as an extractor. Return JSON with keys: company, amount, date. Use null when missing.	80–95%
Summarization	Summarize a report with bullet highlights.	Summarize in five bullets, include risks and next steps, keep under 120 words.	70–90%
Coding	Write a function and include tests.	Write a function, explain edge cases, then provide three tests. Output as Markdown code blocks.	65–90%
Question answering	Answer using provided context only.	Use only the given context. If unsure, say "Not found". Provide a short citation line.	75–95%

Formula used

The calculator estimates how closely your prompt matches your intended task using a weighted score. Each component is scaled to a 0–100 range, then combined.

Total = 100 × clamp01( (wS·Sim + wC·Cov + wT·Struct + wR·Req + Boost) × Len − Penalty )

Sim: cosine similarity between prompt and task token frequencies.
Cov: task keyword coverage inside the prompt.
Struct: presence of required structure signals (role, steps, output, etc.).
Req: requirement satisfaction, plus small format/tone hints.
Boost: small reward for included domain keywords.
Penalty: reduction when forbidden keywords appear.
Len: multiplier that reduces very short or overly long prompts.

How to use this calculator

Paste your prompt in the Prompt box, including role, context, and output rules.
Describe the intended task clearly, including success criteria and constraints.
Select the task type, output format, and tone you expect.
Turn on required elements you want the prompt to contain.
Optionally add domain keywords and forbidden keywords.
Adjust weights if you want the score to favor certain components.
Press Submit to see the score and improvement suggestions above the form.
