Idempotent API

As of	2026-09-19
Version	1.0.0
Kind	spec
Length	53 words, about 1 min
Tags	system-design api idempotency

Idempotent operations that produces the same result no matter how many times you apply it (after the first time). Running it once or a hundred times leaves the system in the same state.

Sidekick’s API endpoints will be idempotent. This makes system safe to retry in case of suspected failures or parallel attempts.

Notes, decisions, and progress on my journey as I build Project Sidekick — built in the open; written as it happens.
