description	Work on a batch of GitHub issues in parallel using Agent Teams. Creates one worktree per issue with TDD enforcement, coordinates via a lead agent, then produces stacked PRs.

/sprint

Work on multiple GitHub issues in parallel. Each issue gets its own worktree with TDD enforcement. A lead agent coordinates, and stacked PRs are created when all work is done.

EXECUTE THESE STEPS NOW

When this skill is invoked, you MUST execute these steps immediately.

Step 0: Check Agent Teams Support

Check if Agent Teams are available:

echo "${CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS:-not_set}"

If the value is not_set or empty, fall back to setup-only mode:

• Parse the comma-separated issue numbers
• Fetch requirements for all issues (parallel issue-worker agents)
• Create worktrees and activate TDD for each
• Report the list of prepared worktrees and tell the user: "Agent Teams not enabled. Worktrees are prepared with TDD active. cd into each worktree and run /write-tests to begin the TDD cycle, or set CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1 and re-run /sprint."
• Do NOT invoke /work-on-issue — it would create duplicate worktrees. The worktrees and TDD markers are already set up.

Step 1: Parse Issue Numbers

Extract comma-separated issue numbers from $ARGUMENTS:

• Remove # prefixes, spaces, and other punctuation
• Example: 67,68,69,70 or #67 #68 #69
• Store as a list: ISSUES=(67 68 69 70)

Step 2: Fetch Requirements (Parallel)

Spawn one issue-worker agent per issue, all in a single message so they run in parallel:

Task tool (ALL in one message):
  For issue 67:
    subagent_type: issue-worker
    description: "issue-worker #67"
    prompt: "Read GitHub issue #67 and extract:
      1. Goal
      2. Acceptance criteria
      3. Edge cases and constraints
      4. Files likely to be touched"

  For issue 68:
    subagent_type: issue-worker
    description: "issue-worker #68"
    prompt: "Read GitHub issue #68 and extract: ..."

  (etc.)

Wait for all agents to return. Collect requirements for each issue.

Step 3: Create Worktrees and Activate TDD

For each issue, create a worktree and activate TDD:

.claude/scripts/worktree-create.sh issue-<N>-<short-desc> && \
  cd .worktrees/issue-<N>-<short-desc> && \
  bash .claude/hooks/tdd-state.sh activate <N> && \
  cd -

Step 4: Check for Conflicts

Before launching parallel work, check if any issues touch the same files:

• Compare the "files likely to be touched" from each issue
• If overlap detected, note it — the lead will need to mediate
• If issues are tightly coupled, warn the user and suggest sequential work

Step 5: Create Agent Team

Create an Agent Team with one teammate per issue.

Lead (delegate mode — coordinates only, does not implement):

• Monitors teammate progress
• Mediates if teammates report conflicts on the same files
• After all complete: collects reports and determines PR ordering

Teammates (one per issue, spawned as parallel Task agents):

Task tool (ALL in one message):
  For issue 67:
    subagent_type: general-purpose
    description: "sprint-teammate #67"
    prompt: |
      You are working on GitHub issue #67.
      Working directory: .worktrees/issue-67-<desc>/
      TDD enforcement is active.

      Requirements:
      <requirements from step 2>

      Your workflow:
      1. cd into your worktree
      2. Create todos from acceptance criteria (TaskCreate)
      3. For each todo, use the Task tool to spawn:
         - subagent_type: tester (to write failing tests)
         - subagent_type: implementer (to make tests pass)
         Then run /update-docs if APIs changed
      4. When all todos complete, report:
         - Files you touched (git diff --name-only)
         - APIs you changed (old → new signatures)
         - Dependencies on other issues (if any)
         - Any conflicts you encountered

  For issue 68:
    subagent_type: general-purpose
    description: "sprint-teammate #68"
    prompt: ...

  (etc.)

Step 6: Collect Results

After all teammates finish, collect from each:

• Files touched
• APIs changed
• Conflict reports
• Test pass/fail status

Step 7: Create Stacked PRs

Spawn the pr-planner agent to determine dependency ordering:

Task tool:
  subagent_type: pr-planner
  description: "pr-planner for sprint"
  prompt: "Given these completed issues and their changes, determine
    the optimal PR ordering. Consider file dependencies, API changes,
    and which PRs can merge independently vs. which must be stacked.

    Issue reports:
    <collected reports>

    Output: ordered list of PRs with base branches"

Then create branches and PRs. For stacked PRs, rebase each branch onto the previous one before creating the PR:

# First PR targets main directly
gh pr create --base main --head issue-67-branch ...

# Subsequent PRs: rebase onto the previous branch first
git checkout issue-68-branch
git rebase issue-67-branch
git push --force-with-lease
gh pr create --base issue-67-branch --head issue-68-branch ...

If rebase conflicts arise, report them to the user rather than auto-resolving.

Step 8: Summary

Output a summary table:

## Sprint Complete

| Issue | PR | Base | Status | Files Changed |
|-------|-----|------|--------|---------------|
| #67 | #XX | main | Created | 3 files |
| #68 | #YY | issue-67-branch | Created | 5 files |
| #69 | #ZZ | issue-68-branch | Created | 2 files |

Stacked PR order: #XX → #YY → #ZZ

When to Use

• Multiple related or independent issues to batch together
• You want maximum parallelism
• Issues are small-to-medium sized (each < ~200 lines of change)

When NOT to Use

• Single issue (use /work-on-issue instead)
• Issues that are tightly coupled and must be done sequentially
• Very large issues (each needs its own focused session)

Requirements

• CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS env var must be set to 1
• Falls back to setup-only mode (worktree creation) if not available
