Complaint Letter

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

The skill verifies itself against its own quality checks: The facts are specific and dated, with reference/order numbers where relevant; The requested resolution is concrete and reasonable — not vague dissatisfaction; A clear, reasonable deadline for response is included; Tone is firm and professional, not abusive (abuse gives them a reason to dismiss you).

Write a firm, effective complaint letter that gets a resolution. Use when asked to write a complaint letter, complain to a company about a product/service, escalate poor service, or demand a refund/replacement. Produces a structured complaint — the facts, the impact, the specific resolution you want, and a deadline — in a firm, professional tone that's hard to ignore and easy to act on.

What to give it

▸What went wrong — the product/service, what happened, and when (dates, order/reference numbers).

▸The impact — how it affected you (cost, time, inconvenience, harm).

▸What you've done — prior contact and their response, if any.

▸What you want — the specific resolution (refund, replacement, repair, apology) and any deadline.

▸Recipient & tone — company/person, and how formal.

✅ 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.

✓The facts are specific and dated, with reference/order numbers where relevant

✓The requested resolution is concrete and reasonable — not vague dissatisfaction

✓A clear, reasonable deadline for response is included

✓Tone is firm and professional, not abusive (abuse gives them a reason to dismiss you)

✓The escalation path is stated as a fact, not an empty threat

✓Both a formal letter and a short email version are provided

⚠️ What it refuses to do

Do not vent without asking for anything — name the specific resolution you want

Do not be abusive or sarcastic — it lets the recipient dismiss the complaint

Do not omit reference numbers and dates — they slow or stall the response

Do not make threats you won't act on — state real next steps factually

Do not bury the ask — the resolution and deadline must be impossible to miss
