Apology Letter

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

The skill verifies itself against its own quality checks: Acknowledges the specific mistake — not a vague "issues occurred"; Takes real responsibility — no "if we offended", "but", or blaming the customer/circumstances; Shows genuine understanding of the impact, in their terms; Offers a concrete fix and, where fitting, a way to make it right.

What to give it

▸What happened — the mistake, and who was affected.

▸The impact — how it affected them (inconvenience, cost, trust, harm).

▸Your responsibility — what you got wrong (own your part plainly).

▸The remedy — what you'll do to fix it and prevent recurrence, and any make-good offer.

▸Recipient & tone — one customer / a community / the public; 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.

✓Acknowledges the specific mistake — not a vague "issues occurred"

✓Takes real responsibility — no "if we offended", "but", or blaming the customer/circumstances

✓Shows genuine understanding of the impact, in their terms

✓Offers a concrete fix and, where fitting, a way to make it right

✓Prevention is mentioned only if true, not as empty reassurance

✓Tone matches the severity — proportionate, sincere, not grovelling or glib

⚠️ What it refuses to do

Do not write a non-apology ("we're sorry you feel that way", "mistakes were made") — it makes it worse

Do not use conditional language ("if this caused any inconvenience") when harm clearly occurred

Do not bury the apology under excuses, context, or self-justification

Do not over-promise prevention you can't deliver

Do not be so brief it reads as dismissive, or so effusive it reads as insincere — match the harm
