Agent Teams — Parallel Subagent Coordination

Enabled via CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1 in ~/.claude/settings.json. Windows constraint: teammateMode: "in-process" only — no subprocess spawning.

When to Use Agent Teams

Agent Teams are worth the coordination overhead only when:

• The task has clearly separable, non-dependent workstreams
• Each workstream would take > 10 minutes alone
• At least 2 different specializations are needed simultaneously

Do NOT use for:

• Simple fixes (< 3 files) — delegation overhead exceeds task effort
• Tasks where output of step A is input to step B (sequential, not parallel)
• Content creation — content-writer runs alone to preserve voice consistency
• Memory/state updates — always single-agent to prevent write conflicts

Spawning a Teammate

Natural language trigger — no slash command needed. Just describe the parallel need:

"Spawn a teammate using the security-reviewer agent to audit the auth flow while I implement the new endpoint."

"Run the code-reviewer and debugger agents in parallel on this PR."

Claude Code will automatically spawn the teammate agent with the appropriate definition from .claude/agents/.

Available Subagent Definitions (.claude/agents/)

File	Agent	Model	Best For
security-reviewer.md	security-reviewer	sonnet	Auth flaws, RLS gaps, credential exposure, OWASP checks
researcher.md	researcher	sonnet	Multi-source research, doc lookup, competitive analysis
code-reviewer.md	code-reviewer	sonnet	Two-pass structural + adversarial code review
content-writer.md	content-writer	opus	Platform content in CC's voice (X, LinkedIn, IG, TikTok)
debugger.md	debugger	sonnet	Root-cause debugging, 5 Whys, bisect regressions
architect.md	architect	opus	System design, DB schema, API contracts, ADRs

Communication Patterns

Mailbox Pattern (preferred)

Bravo writes a scoped task to a temp file → teammate reads it → teammate writes output to a result file → Bravo reads result.

tmp/teammate-task-{agent}-{timestamp}.md   ← Bravo writes the task
tmp/teammate-result-{agent}-{timestamp}.md ← Teammate writes findings

Shared Task List

For longer parallel runs, use .agents/plans/active-{task}.md as a shared task list both agents can read. Bravo owns writes; teammate reads only.

Parallel Execution Patterns

Pattern A: Review While Building

Bravo:    Implements the feature
Teammate: code-reviewer audits existing changes in parallel
Result:   Review ready when implementation is done — no waiting

Pattern B: Security Sweep + Feature Ship

Bravo:    Ships the feature (test → changelog → PR)
Teammate: security-reviewer audits auth surface in parallel
Result:   Security sign-off attached to the PR

Pattern C: Research + Architect

Bravo:    Researches competitive landscape (researcher agent)
Teammate: architect drafts system design while research runs
Result:   Design informed by findings, both complete simultaneously

Pattern D: Debug + Implement Workaround

Bravo:    Implements short-term workaround to unblock CC
Teammate: debugger traces root cause in parallel
Result:   Fix applied now, root cause known for proper patch later

Windows Limitations

• teammateMode: "in-process" — teammates share the same process, no subprocess isolation
• No worktree isolation on Windows (architect agent lists isolation: worktree but this is advisory — use with care on shared files)
• If two agents attempt to write the same file simultaneously, the last write wins — coordinate via separate output files

Anti-Patterns

1. Spawning a teammate for a < 5-minute task — overhead exceeds benefit
2. Both agents writing to the same file — causes race conditions
3. Delegating memory writes (brain/, memory/) to a teammate — Bravo owns state
4. Running content-writer as a teammate — voice consistency requires single-agent execution
5. Ignoring teammate output — always read and present findings to CC

Integration with Existing Routing

This skill extends skills/task-routing/SKILL.md. When task routing classifies a task as COMPLEX or ARCHITECTURAL, consider splitting across teammates:

Routing Tier	Team Configuration
MODERATE	Optional: spawn code-reviewer in parallel
COMPLEX	Recommended: Bravo (frontend/orchestration) + teammate (backend/security)
ARCHITECTURAL	Recommended: architect teammate drafts spec, Bravo implements
