Reference Letter

Q: How do I know the Reference Letter output is good?

The skill verifies itself against its own 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.

What to give it

▸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.

✅ The bar it holds itself to

Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.

✓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

⚠️ What it refuses to do

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
