okl - Observed Knowledge Ledger: Guardrails and a Learning Loop for AI Coding Agents
Records engineering rules, architecture decisions and docs once, briefs the coding agent before every task via a Claude Code hook or MCP, proves rules with checks, and flags drift before push or in CI.
Why it matters
Each session's lessons feed back into the ledger, so agent guardrails improve over time instead of rotting in a wiki nobody reads.
What you could build with it
An engineering consultancy could deploy okl across every client repo it touches, building a shared ledger of architecture decisions that keeps contracted AI agents consistent with each client's standards without manual briefing.
Does it hold up?
Too early to judge: 2 stars, repo from 2026-08-30, surfaced on HN today; installable from PyPI but no independent adoption reports yet.
