The Compound Engineering plugin is an official tool for Claude Code, Codex, Cursor, and related AI development environments, written in TypeScript and designed to improve how engineering work compounds over time. Rather than allowing technical debt to accumulate with each feature, the plugin implements a philosophy where each unit of work should make subsequent units easier by emphasizing planning, review, and knowledge codification over raw execution speed.
The plugin operates around a core six-step workflow loop: brainstorm requirements through interactive Q&A, plan implementations with enriched detail, execute work through structured task tracking, simplify freshly written code for clarity, conduct multi-agent code review against the plan, and finally compound learnings into reusable documentation. This cycle repeats with improving context as each iteration feeds knowledge back into the next brainstorm and planning phase. The brainstorm skill explores requirements and writes right-sized requirements documents, the plan skill creates structured implementation plans, the work skill executes those plans systematically using git worktrees and task tracking, the simplify-code skill refines fresh implementations before review, the code-review skill applies multi-agent review patterns, and the compound skill captures learnings into a solutions directory for future reference.
Beyond the core loop, the plugin includes additional skills that sit around or branch from the main workflow. The ideate skill generates and critically ranks grounded ideas before entering the loop, the strategy skill creates and maintains a STRATEGY.md file that grounds all downstream decisions, the product-pulse skill generates time-windowed reports on actual user experience including usage and errors, and the debug skill handles bug fixes as a specialized path instead of the standard feature loop. The explain skill turns concepts, diffs, or work windows into personal learning artifacts, while the pov skill forms decisive verdicts on whether to adopt external technologies or patterns.
The plugin ships 28 distinct skills covering the full development lifecycle. Beyond planning and review, it includes skills for browser testing, iOS app testing via Xcode, git operations like commit and push, autonomous PR opening, user-facing announcement drafting, and hands-off autonomous workflows. The lfg skill runs the entire pipeline autonomously: planning, implementation, simplification, code review with fixes, browser testing, committing, pushing, and PR opening with CI monitoring and autonomous repair until tests pass green.
