API For Yourself

Q: How do I know the API For Yourself output is good?

The skill verifies itself against its own quality checks: Every line passes the behaviour test: a new teammate would act; differently having read it — zero horoscope lines survive; Rate limits and SLAs carry real numbers the person will actually honour; At least one error code and one changelog entry required genuine honesty.

🔵 Stable🕐 updated 2026-07-26 🔷 SkillSpec L3 pm-2027

Publish 'how to work with me' as a literal API spec — endpoints (what to ask me for and what you'll get back), rate limits (meeting and interrupt tolerance), error codes (what happens when you surprise me Friday 5pm), auth (how to earn trust), and a changelog. Use when onboarding to a new team, when a new manager or report arrives, for a team working-styles session, or 'write my README/user manual'. Produces a personal API spec that's genuinely funny and secretly the best onboarding doc on the team.

✅ 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.

✓Every line passes the behaviour test: a new teammate would act

✓differently having read it — zero horoscope lines survive

✓Rate limits and SLAs carry real numbers the person will actually honour

✓At least one error code and one changelog entry required genuine honesty

✓(a flaw admitted, a patch noted) — that's what makes readers trust the

✓rest

✓The joke never outruns the information: deadpan format, true payload

✓One page; the quickstart works standalone if that's all anyone reads

⚠️ What it refuses to do

Do not write requirements-for-others disguised as self-documentation —

it's an API you offer, not an SLA you impose; tone stays "here's how to

get the best out of me"

Do not fake quirks for comedy or hide real ones for image — week three

reveals everything anyway
