Prompt

Act as an expert writer of professional and academic recommendation letters.

Context:
- Who signs the letter (name, title, organization): {{signer}}
- Person being recommended and their role: {{candidate}}
- Relationship and duration: {{relationship}}
- What the letter is for (job, graduate program, scholarship, volunteering): {{purpose}}
- Achievements or concrete examples I can confirm: {{examples}}
- Qualities I want to highlight: {{qualities}}
- Honest level of recommendation: {{level}}

Deliverables:
1. The letter (300-450 words): introduction of the signer and the relationship; two or three concrete examples with situation, action and result; qualities shown through those examples (not just listed); an honest comparative statement if I can back it up (e.g., "among the three most rigorous people I have supervised"); a final recommendation matching the chosen level; an offer to be contacted.
2. A short version (120-150 words) for online forms.
3. A list of claims in the letter that I must be able to support if someone calls to verify.

Constraints:
- Do not invent achievements, numbers, dates or awards. Use [FILL IN: real detail] where information is missing.
- Avoid empty adjectives ("excellent", "amazing") without an example to support them.
- If the recommendation level is moderate, do not exaggerate: honestly highlight real strengths.
- Do not include sensitive personal data (health, family situation, background) about the candidate.
- If concrete examples are missing, ask me before writing.

Format: the full letter with header and signature, the short version and the verification list.

How to use it

Ask the candidate to remind you of specific projects and results, and fill in the variables with what you can confirm. Adapt the letter to its purpose (job or academic) and sign it with your real contact details.

Usage example

Signer: Anna Reed, lab manager · Candidate: Paul Diaz, lab technician · Relationship: supervised him for 3 years · Purpose: master's in biotechnology.

Sample output

Recommendation letter (excerpt)

Anna Reed Lab Manager · Boston Biomedical Research Institute [FILL IN: email and phone]

Dear Admissions Committee,

I am pleased to recommend Paul Diaz, a lab technician I have supervised directly for three years.

Shortly after joining, Paul noticed that our sample inventory was producing duplicates and wasted time. On his own initiative, he redesigned the logging protocol and proposed it to the team; it has been our daily system ever since. [FILL IN: real detail, e.g. time saved or fewer errors].

He also trained two interns. He prepared step-by-step materials and made sure they could work independently within a few weeks, which takes clear, patient communication.

His rigor shows in the details: he checks every label, documents every change and asks when something does not add up instead of assuming.

For these reasons, I recommend Paul without reservation for your master's program in biotechnology. I would be glad to provide further information.

Sincerely, Anna Reed

Claims you must be able to support

  • Three years of direct supervision.
  • Redesign of the inventory protocol and its current use.
  • Training of two interns…
