Seth Hobson fb9eba62b2 fix(agent-teams): remove Context7 MCP dependency, align frontmatter with conductor patterns, bump to v1.0.1
Remove .mcp.json to eliminate external MCP dependency that likely caused plugin load failure.
Add tools: field to all agents, version: field to all skills, matching conductor plugin patterns.

# Team Composition Patterns
Best practices for composing multi-agent teams, selecting team sizes, choosing agent types, and configuring display modes for Claude Code's Agent Teams feature.
## When to Use This Skill
- Deciding how many teammates to spawn for a task
- Choosing between preset team configurations
- Selecting the right agent type (subagent_type) for each role
- Configuring teammate display modes (tmux, iTerm2, in-process)
- Building custom team compositions for non-standard workflows
## Team Sizing Heuristics
| Complexity | Team Size | When to Use |
| ------------ | --------- | ----------------------------------------------------------- |
| Simple | 1-2 | Single-dimension review, isolated bug, small feature |
| Moderate | 2-3 | Multi-file changes, 2-3 concerns, medium features |
| Complex | 3-4 | Cross-cutting concerns, large features, deep debugging |
| Very Complex | 4-5 | Full-stack features, comprehensive reviews, systemic issues |
**Rule of thumb**: Start with the smallest team that covers all required dimensions. Adding teammates increases coordination overhead.
## Preset Team Compositions
### Review Team
- **Size**: 3 reviewers
- **Agents**: 3x `team-reviewer`
- **Default dimensions**: security, performance, architecture
- **Use when**: Code changes need multi-dimensional quality assessment
### Debug Team
- **Size**: 3 investigators
- **Agents**: 3x `team-debugger`
- **Default hypotheses**: 3 competing hypotheses
- **Use when**: Bug has multiple plausible root causes
### Feature Team
- **Size**: 3 (1 lead + 2 implementers)
- **Agents**: 1x `team-lead` + 2x `team-implementer`
- **Use when**: Feature can be decomposed into parallel work streams
### Fullstack Team
- **Size**: 4 (1 lead + 3 implementers)
- **Agents**: 1x `team-lead` + 1x frontend `team-implementer` + 1x backend `team-implementer` + 1x test `team-implementer`
- **Use when**: Feature spans frontend, backend, and test layers
### Research Team
- **Size**: 3 researchers
- **Agents**: 3x `general-purpose`
- **Default areas**: Each assigned a different research question, module, or topic
- **Capabilities**: Codebase search (Grep, Glob, Read), web search (WebSearch, WebFetch)
- **Use when**: Need to understand a codebase, research libraries, compare approaches, or gather information from code and web sources in parallel
### Security Team
- **Size**: 4 reviewers
- **Agents**: 4x `team-reviewer`
- **Default dimensions**: OWASP/vulnerabilities, auth/access control, dependencies/supply chain, secrets/configuration
- **Use when**: Comprehensive security audit covering multiple attack surfaces
### Migration Team
- **Size**: 4 (1 lead + 2 implementers + 1 reviewer)
- **Agents**: 1x `team-lead` + 2x `team-implementer` + 1x `team-reviewer`
- **Use when**: Large codebase migration (framework upgrade, language port, API version bump) requiring parallel work with correctness verification
## Agent Type Selection
When spawning teammates with the Task tool, choose `subagent_type` based on what tools the teammate needs:
| Agent Type | Tools Available | Use For |
| ------------------------------ | ----------------------------------------- | ---------------------------------------------------------- |
| `general-purpose` | All tools (Read, Write, Edit, Bash, etc.) | Implementation, debugging, any task requiring file changes |
| `Explore` | Read-only tools (Read, Grep, Glob) | Research, code exploration, analysis |
| `Plan` | Read-only tools | Architecture planning, task decomposition |
| `agent-teams:team-reviewer` | All tools | Code review with structured findings |
| `agent-teams:team-debugger` | All tools | Hypothesis-driven investigation |
| `agent-teams:team-implementer` | All tools | Building features within file ownership boundaries |
| `agent-teams:team-lead` | All tools | Team orchestration and coordination |
**Key distinction**: Read-only agents (Explore, Plan) cannot modify files. Never assign implementation tasks to read-only agents.
## Display Mode Configuration
Configure in `~/.claude/settings.json`:
```json
{
"teammateMode": "tmux"
}
```
| Mode | Behavior | Best For |
| -------------- | ------------------------------ | ------------------------------------------------- |
| `"tmux"` | Each teammate in a tmux pane | Development workflows, monitoring multiple agents |
| `"iterm2"` | Each teammate in an iTerm2 tab | macOS users who prefer iTerm2 |
| `"in-process"` | All teammates in same process | Simple tasks, CI/CD environments |
## Custom Team Guidelines
When building custom teams:
1. **Every team needs a coordinator** — Either designate a `team-lead` or have the user coordinate directly
2. **Match roles to agent types** — Use specialized agents (reviewer, debugger, implementer) when available
3. **Avoid duplicate roles** — Two agents doing the same thing wastes resources
4. **Define boundaries upfront** — Each teammate needs clear ownership of files or responsibilities
5. **Keep it small** — 2-4 teammates is the sweet spot; 5+ requires significant coordination overhead
