Autonomous Build-Test-Ship Loop

Pillar: autonomous-build-loop | Date: April 2026
Scope: CC 2026 automation primitives: PostToolUse hooks for format/lint/test, CronCreate for scheduled agents, /loop self-pacing, --print headless mode, Task with isolation:worktree, EnterWorktree, plan mode. Tool comparison for autonomous agents: Aider auto-commit, Cursor Composer, Devin headless, Sweep PR-from-issue, Goose loops, Codex CLI, Cline/RooCode. Continuous quality patterns in agent loops: mutation testing (Mutmut, Stryker), property-based testing (Hypothesis, fast-check), security scanning (Semgrep, Snyk), perf regression watchers. Real public configs.
