Claude Code Workflows

Beyond basic single-task use, Claude Code supports more advanced workflows for handling larger or more complex engineering work.

Subagents. For large or multi-part tasks, Claude Code can delegate portions of the work to subagents that operate somewhat independently, often in parallel, before their results are reconciled. This is useful for work that naturally splits into separate pieces — for example, building several independent UI components at once — since it can significantly reduce the total time a large task takes compared to doing everything sequentially.

Verification and review passes. A common and effective pattern is having Claude Code (or a dedicated subagent) review its own or another agent's work after the main implementation is done — checking for integration issues, bugs at the boundaries between separately-built pieces, or deviations from a stated plan. This catches problems that individual builders working in isolation might miss.

Working from a written plan. For larger projects, it's common to have Claude Code work from a detailed specification document — describing the architecture, design decisions, and a phase-by-phase build order — rather than giving it the whole task as one large, underspecified instruction. This produces more consistent, reviewable results, especially across a project that spans many work sessions.

Session management. Long or complex work often benefits from managing context deliberately between phases — for example, clearing or compacting the conversation between distinct pieces of work so the model isn't carrying irrelevant history forward, while preserving what's actually still relevant.

Planning before executing. For consequential changes, it often pays to separate deciding from doing: have the tool explore the codebase and propose a plan first, review that plan yourself, and only then let execution begin. Reviewing a plan takes minutes; unwinding a wrong implementation can take much longer. This pattern also surfaces misunderstandings — a wrong assumption about the architecture, a missed constraint — at the point where correcting them costs almost nothing.

Version control as a safety net. Agentic workflows lean heavily on ordinary engineering hygiene, and version control is the most important piece. Committing between phases gives every stage a clean rollback point; reviewing diffs before committing keeps a human's eyes on everything that changed; and working on a branch keeps in-progress agentic work isolated from the main line until it has been verified. None of this is new advice — it is the same discipline that makes any collaboration safe, applied to a very fast collaborator.

Choosing what to parallelize. Subagents shine when work divides into genuinely independent pieces: separate components, separate documents, separate investigations. They are the wrong tool when every piece depends on decisions made in the others — parallel workers making conflicting assumptions produce integration debt faster than they produce progress. The judgment to build is recognizing which kind of task you are looking at before splitting it, and keeping tightly-coupled work in a single sequential session where one line of reasoning can hold all the constraints at once.

Right-sizing the task. Experienced users develop a feel for the unit of work that produces reliable results: large enough to be worth delegating, small enough to verify meaningfully when it comes back. "Rebuild the entire app" invites sprawling, hard-to-review output; a phase of a written plan, with clear boundaries and a defined done-state, comes back in a shape a person can actually check. When a task feels too big to review, that is usually the signal to split it — in the plan, before execution starts.

Common pitfalls. The recurring failure modes are predictable. Skipping the verification pass on multi-part work leaves boundary bugs undiscovered until integration. Letting a session's context grow without bound degrades the quality of later work in that session. Over-parallelizing coupled work creates contradictions no single agent would have produced. And vague delegation — a one-line request for a week's worth of work — produces output whose problems are as large and vague as the request was. Each pitfall has the same antidote: structure the work before delegating it.

Building the habit. None of these patterns needs to be adopted all at once. A reasonable progression is to start with plan-first execution on a single meaningful task, add a verification pass once multi-file changes become routine, bring in subagents when a task with genuinely independent parts appears, and tighten session management as projects stretch across multiple sittings. Each pattern earns its place by solving a problem you have actually hit — which is also how you learn where each one genuinely helps rather than adds ceremony.

Putting it together. A well-run large project typically combines all of these patterns: a written plan sets the direction, work is split across parallel subagents where it naturally divides, a verification pass audits the seams between what each subagent built, version control provides checkpoints between phases, and context is managed deliberately rather than left to accumulate indefinitely. These workflow patterns are what separate effective large-scale use of Claude Code from simply asking it to "build the whole thing" in one go and hoping for the best.
