Legacy Letter

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

The skill verifies itself against its own quality checks: The letter is built from specific, true memories and feelings — zero generic; "I'm so proud" filler standing alone; It sounds like the writer (their cadence, humor, words), not a greeting card or; funeral speech.

Write a letter to the people you love, to be read later — the things you'd want them to know, the stories only you hold, the permission and the love that outlive you. Use when someone says 'help me write a letter to my kids/partner', 'legacy letter', 'ethical will', 'something for them to have when I'm gone', or is facing illness, aging, deployment, or simply wants to. Produces a warm, true letter in the writer's own voice — one to each person, or one to all — plus a light plan for when and how it's found. An emotional-legacy tool, not legal (it is not a will).

✅ 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 letter is built from specific, true memories and feelings — zero generic

✓"I'm so proud" filler standing alone

✓It sounds like the writer (their cadence, humor, words), not a greeting card or

✓funeral speech

✓Any apology/permission/blessing came from the writer, never invented by the skill

✓It's pitched to the reader's actual age/moment, especially if read in the future

✓There's a plan for it to be found, and it's framed as revisable/living

⚠️ What it refuses to do

Do not write in inflated funeral prose or platitudes — specificity and the real

voice are the entire value

Do not invent memories, feelings, or apologies the writer didn't give — this is

their letter, sacred and true; the skill is a scribe, not an author

Do not treat this as a will — it carries no legal weight; if the writer starts
