What Mainline does

Mainline records AI work intents, tracks autonomy boundaries, and links changes to commits and PR handoffs. Use it in git repos when coordinating agent edits, conflict checks, sealing, pushes, or review boundaries.

Mainline is cataloged under AI Engineering on DirSkills. Mainline comes from a repository tagged agent-context, agent-memory, ai-agents, ai-code-review and ai-coding.

Documentation

README

Mainline

This skill is the agent-facing Mainline integration. It should be sufficient even when the repository does not yet have Mainline text in AGENTS.md and when Mainline hooks are not installed.

Mainline records why AI-driven changes happen, connects those intents to code commits, and surfaces semantic conflicts before PR review. Treat it as part of the coding workflow, not as optional documentation.

If the current session already contains a mainline:context block injected by Mainline hooks, treat that hook context as already loaded. Do not re-run generic bootstrap context commands just to duplicate it. Run task-specific context commands only when needed.

Architecture Decision Records

Architecture Decision Records captures architectural decisions made during Claude Code sessions as structured ADRs, recording context, alternatives, and rationale. Use it when significant technical choices are made so future developers understand why the codebase is shaped the way it is.
