# Finding DeepSeek Harness Simplifications This skill helps turn a broad "find things to simplify" request into evidence-backed Agent Notes that remove or collapse existing harness surface area. It is guidance, not a checklist: follow the code, keep judgment active, and prefer a few well-proven candidates over a pile of thin guesses. ## Start With Repo Context - Read `AGENTS.md`, especially the pre-release stance and the conventions (including the tests-are-not-golden-truth and Agent Notes-are-not-golden-truth doctrines), plus [docs/defensive-patterns.md](../../../docs/defensive-patterns.md) and [docs/testing.md](../../../docs/testing.md). - Skim [docs/architecture.md](../../../docs/architecture.md) before judging anything under `packages/`; simplifications that fight the service map or event taxonomy need extra evidence. - Use the Agent Note tree and its [rules](../../notes/README.md) to understand intentional architecture. The most relevant implemented examples are [drop mutable session summary](../../notes/implemented/simplification/2026-06-19-drop-mutable-session-summary.md), [shared persistence write coordinator](../../notes/implemented/architecture/2026-06-18-shared-persistence-write-coordinator.md), [capability seams](../../notes/implemented/architecture/2026-06-13-capability-seams.md), and the twin adapter / dual persistence backend Agent Notes. - Treat dual LLM adapters and dual persistence backends as intentional by default. Do not propose deleting either twin/ba
