Claude Code Subagents for Team Workflows
Use subagents only when the work has a clean boundary. In Claude Code, the feature pays off for a Claude team when one person can name the job, the allowed files, and the review evidence before any agent starts.
That matters for Claude Code agent teams because parallel work multiplies ambiguity. A small convention gives each Claude agent a role, a stop condition, and a handoff format instead of letting several chats improvise against the same repo.
Give each agent one boundary
The phrase Claude Code subagents can make the feature sound larger than it needs to be. I would treat a subagent as a bounded worker with one role, one part of the repo, and one expected output.
A good boundary is boring. For a GitHub PR workflow in a web repo, one subagent can update an API handler and its tests, another can run the UI regression path, and the owner keeps the final branch and PR description. Do not ask three agents to edit the same files unless the point of the exercise is conflict resolution.
This belongs in your Team conventions, not in memory alone. CLAUDE.md can carry durable repository rules, but the subagent convention should say how the team delegates work this week.
Choose the smallest working shape
Start with the smallest shape that reduces coordination cost. Agent teams in Claude Code are useful when the work can be split, reviewed, and recombined without losing ownership.
| Shape | Use it when | Limit |
|---|---|---|
| One Claude Code session | The task needs one chain of context and one set of edits. | Faster to run, but easy to overload with mixed goals. |
| One subagent | A role can own a narrow task such as test repair, migration review, or docs cleanup. | Needs a clear stop condition or it will keep exploring. |
| Claude Code agent teams | Two or more independent workstreams can run in parallel and hand back evidence. | Requires an owner to merge decisions, not just outputs. |
| Claude Code Agent SDK workflow | You need repeatable orchestration around agents, not just an interactive session. | Worth the setup only when the workflow repeats often. |
This is the Delegate step of our methodology: name the work before the model starts. The review gets easier because the role, files, and evidence were fixed up front.
Paste this convention before the first run
Use a short operating checklist. Put it in a repo runbook, a team convention page, or a project-specific Claude Code folder where people will actually read it.
# Claude Code subagent operating checklist
Before assigning a subagent:
- Name the owner who will merge or reject the result.
- Name the subagent role in one sentence.
- List the files, folders, or commands the role may touch.
- List the files, folders, or systems it must not touch.
- State the expected output: patch, test result, summary, migration note, or review comment.
- State the stop condition: passing command, answered question, blocked reason, or time box.
- State any MCP access needed and why.
- State any hooks or checks that must pass before the owner reviews the work.
During the run:
- Keep one subagent per workstream.
- Do not let two subagents edit the same file unless the owner has planned the merge.
- Ask each subagent to report changed files, commands run, and unresolved risks.
Before merging:
- The owner reads the diff.
- The owner runs or verifies the agreed checks.
- The owner records what was accepted, rejected, or rerun.
Adoption path: the engineer proposing the agent split writes the checklist for the first task, the reviewer checks the boundaries before the run, and the team stores the final convention beside the workflow it governs. Do not bury this in a long root memory file unless it is a durable rule for every task in the repository.
Review rule: a subagent result is not complete until the owner can see the diff, the commands run, and the remaining risk. If the output is only a chat summary, ask for evidence before using it.
Keep integrations on a short leash
Subagents should not get wider MCP access just because they are running in parallel. Give each role only the external systems it needs, and write that reason into the checklist.
For example, a docs subagent may need repository read access and no ticketing access. A release-note subagent may need GitHub and the changelog, but not the database. If you are still shaping those boundaries, the same permission habit applies in Set Up Claude Code MCP Safely.
Hooks are useful as guardrails, not as a replacement for ownership. A hook can enforce a command or capture a receipt, but a human still decides whether the work should merge.
