Reference Letter Skill
A reference is believed when it's specific: concrete examples beat adjectives, and the reader can tell you
actually know the person. This skill writes a letter that establishes your credibility to comment, gives real
evidence of the person's strengths, and makes a clear, tailored recommendation for the decision at hand.
Working from a brief
Given "write a reference for my report applying for a senior role", write the full letter anyway — infer
plausible, concrete examples from the relationship described, clearly marking invented specifics as
(example — replace with a real instance) so the writer swaps in true details. Never hand back a hollow
template of adjectives.
Required Inputs
Ask for these only if they aren't already provided (else infer and label for replacement):
Who & what for — the person, and what they're applying for (job/role, school/program, tenancy).
Your relationship — how you know them, in what capacity, and for how long.
Their strengths — the qualities/skills to highlight, ideally with real examples.
The reader's priorities — what the recipient is deciding and what matters to them.
Tone & format — formal letter vs. email; and any length limit.
Output Format
Reference Letter
Opening — who you are, your relationship to the candidate, how long and in what capacity (establishes credibility).
Endorsement — a clear statement of your recommendation up front.
Evidence — 2–3 specific examples that demonstrate the strengths that matter for this decision (a result, a behaviour, a moment) — not a list of traits.
Comparative context — where appropriate, how they stand out ("one of the most … I've worked with"), kept honest.
Fit for the role — tie their strengths directly to what the reader is deciding.
Close — a confident final recommendation and an offer to discuss, with contact details.
Mark any invented specifics as (example — replace with a real instance). Provide a shorter version if useful.
Quality Checks
Your credibility to comment is established (relationship, capacity, duration)
Strengths are shown with specific examples, not just adjectives
The endorsement is tailored to what the reader is actually deciding
Comparative praise is concrete and honest, not inflated to meaninglessness
Invented specifics are clearly marked for the writer to replace with real ones
The recommendation is unambiguous — the reader knows exactly where you stand
Anti-Patterns
Do not rely on generic adjectives ("hardworking, dedicated") with no evidence — they signal nothing
Do not present invented examples as real — mark them for replacement
Do not write a one-size-fits-all letter — tailor the evidence to the decision
Do not overpraise to the point of incredibility — calibrated specifics are more persuasive
Do not bury the recommendation — make your endorsement explicit and early

Recommendation-writing practice — establishing credibility, evidence over adjectives, comparative endorsement, and tailoring to the reader's decision.
