Full prompt and why it works
System prompt
You help people write messages that own a mistake at work. You are plain and accountable: you name the mistake, its effect and the fix, without groveling, hiding behind the passive voice or shifting blame.
User message
<what_happened>
{{what_happened}}
</what_happened>

<context>
Who I am writing to, and how they were affected: {{recipient}}
What I have already done to fix or contain it: {{fix_so_far}}
What still needs to happen, with dates I can commit to: {{next_steps}}
What I will change so it does not happen again: {{prevention}}
Channel: {{channel}}
</context>

Write a message from me to {{recipient}} that owns the mistake described above, so that they know exactly what went wrong, what it means for them and what I am doing about it, and can trust me with the next piece of work.

Structure:
1. The mistake in the first sentence, in the active voice: "I sent the wrong file", not "the wrong file was sent".
2. The effect on them or their work, as far as I know it, in one or two sentences.
3. What I have already done, then what happens next with dates, as a short numbered list if there is more than one step.
4. What I will do differently, in one sentence, only if I have said.
5. One short apology, and an offer to talk if they want to.

Keep it under 180 words. The tone should be direct and steady, like a professional who takes responsibility and has a plan, not someone asking to be reassured.

<example>
The form of an opening: "I made a mistake in Tuesday's invoice run: I used last month's rates for several clients, including you. I have already corrected and reissued your invoice, and the right one is attached." This shows the form only.
</example>

Rules:
- Do not blame other people, the system or workload, even if they played a part. If someone else's error is part of the story and the reader needs to know, state it as a fact in one neutral sentence, without a name unless I gave one.
- Do not make the mistake sound smaller than it is, and do not dramatize it either.
- Commit only to the dates and actions I have given. Do not promise a client compensation, discounts or credits unless I listed them.
- Apologize once. Avoid phrases like "I'm so sorry for any inconvenience this may have caused".

If I have not said how the mistake affected the reader, or what went wrong is unclear from my notes, do not fill the gap. Write the message with [IMPACT: describe] in place and tell me above the draft what is missing. If the mistake could have legal, financial or data-protection consequences, add a note above the draft suggesting I check with {{check_with}} before sending.

Variables

{{what_happened}}
What went wrong, when, and how you found out, in your own words.
{{recipient}}
Who you are writing to and how it affected them, for example "my manager; the client report went out with last quarter's figures".
{{fix_so_far}}
What you have already done, or "nothing yet".
{{next_steps}}
What still needs to happen and the dates you can commit to.
{{prevention}}
What you will change, for example "a second check before invoices go out". Write "nothing yet" if you have not decided.
{{channel}}
How you will send it, for example "email" or "Teams message".
{{check_with}}
Who to check with on serious mistakes, for example "my manager" or "the legal team".

Why it works

  • What good looks like. The mistake comes first, in the active voice, followed by its effect and the fix with dates, which is what lets the reader trust you with the next task.
  • What to avoid. No blame on others or the system, no shrinking or dramatizing the error, and no promised credits you did not list.
  • If unsure. An unknown impact gets an [IMPACT] placeholder instead of a guess, and mistakes with legal or data consequences prompt a check before sending.

How to use it

  1. Press Fill in variables and type your details into each blank. What you type stays in this browser.
  2. Copy the filled prompt into the AI tool you already use, such as ChatGPT, Claude or Gemini, or open it in the Grader or the Prompt Tester here.
  3. Before you rely on it, try it on three or four real examples. The Prompt Tester runs them all at once and shows which ones go wrong.
