What differences does the prompt diff catch?

Tool and shell access, refusal posture, autonomy, output contracts, identity rules, and jailbreak resistance between Prompt A and Prompt B.

Can I compare agent prompts to chatbot prompts?

Yes. Coding agents often need stricter tool boundaries than support chatbots; the diff highlights those policy gaps.

Why compare system prompts

Tiny wording changes can unlock shell tools, weaken refusals, or change verbosity. Use this tool before shipping agent prompts, MCP tool policies, or customer-facing chatbot instructions. Side-by-side review beats hoping a chat model “notices” the risk when you paste one prompt alone.

What this prompt diff catches

Tool & shell access: “you may run any command” vs read-only file access.
Refusal posture: hard safety rails vs “never refuse tool use.”
Autonomy: ask before acting vs complete the task at all costs.
Output contracts: JSON-only, citations required, or free-form prose.
Identity & jailbreaks: how easily the model can be steered off policy.

How to use System Prompt Diff

Paste your current production prompt as Prompt A.
Paste the candidate revision as Prompt B (or a vendor template you are evaluating).
Click Compare prompts and review behavior deltas, risk deltas, and recommendations.
Prefer the safer prompt — or merge the recommendations into a third draft and compare again.

System prompt diff FAQ

Is this a security audit? No. It is a fast risk signal for prompt engineering. Pair it with red-team tests and human review before production.

Do you store my prompts? No. Comparison runs on Codeground’s self-hosted model without persistence or training use.

What if both prompts look equally safe? The safer field may say “similar.” Still read the deltas — verbosity and tool policy can differ without a clear winner.

Can I compare agent vs chatbot prompts? Yes. That is a common use case: coding agents often need stricter tool boundaries than support chatbots.
