# Agent Types

Choose the right agent type for each role in your team. Agent types determine what tools are available and what the agent is optimized for.

## Agent Type Selection Guide

| Need | Agent Type | Why |
|------|-----------|-----|
| Search/read code | **Explore** | Read-only, fast, cheap (haiku) |
| Architecture design | **Plan** | Read-only, thoughtful analysis |
| Run commands/git | **Bash** | Shell access only |
| Multi-step implementation | **general-purpose** | Full tool access |
| Claude Code questions | **claude-code-guide** | Docs and web access |
| Security review | **sdlc:security-reviewer** | Vulnerability assessment, secure coding |
| Code quality review | **sdlc:quality-enforcer** | Formatting, linting, code style |
| Code simplification | **code-simplifier:code-simplifier** | Clarity, consistency, minimalism |
| Architecture analysis | **refactor:architect** | Design review, optimization planning |
| Best practices research | **adr:adr-researcher** | Codebase analysis + web research |
| Deep code exploration | **feature-dev:code-explorer** | Trace execution paths, map architecture |
| Code review | **feature-dev:code-reviewer** | Bugs, logic errors, conventions |
| Source code chunk analysis | **swarm:rlm-code-analyzer** | Code-aware, scope context, analysis focus |
| Data/CSV chunk analysis | **swarm:rlm-data-analyzer** | Column-aware, distributions, statistics |
| JSON chunk analysis | **swarm:rlm-json-analyzer** | Schema-aware, structural patterns |
| General chunk-level analysis | **swarm:rlm-chunk-analyzer** | Haiku, fast, structured JSON output |
| Synthesize chunk findings | **swarm:rlm-synthesizer** | Sonnet, aggregation and deduplication |

**Key rule:** Match the agent's tool access to the task requirements. Read-only agents (Explore, Plan) **cannot** edit or write files. Never assign them implementation work.

### RLM Agents

Content-aware chunk analyzers — the Team Lead selects the analyst based on detected content type.

**Single-file mode:** One analyst type per session (determined by content type).
**Multi-file mode:** Different analyst types run simultaneously when a directory contains mixed content types. 1 analyst per task (fresh context each), distributed proportionally across content types, staged spawning in batches of ~15 for large workloads. See [Multi-File Directory Analysis](../rlm-pattern/SKILL.md#multi-file-directory-analysis).

**IMPORTANT:** In actual RLM workflows, spawn these as **teammates** (with `team_name` + `name`) so they communicate via `SendMessage` instead of dumping results into the leader's context. In multi-file mode, analysts write findings to task descriptions via `TaskUpdate` and send only one-line summaries to team-lead. See [RLM Pattern](../rlm-pattern/SKILL.md) for the full team lifecycle. The examples below show the `subagent_type` syntax only:

```javascript
// Source code analysis (code-aware boundaries)
Task({
  subagent_type: "swarm:rlm-code-analyzer",
  description: "Analyze code chunk",
  prompt: "Query: Review for security issues\nFile: /tmp/rlm-chunks/chunk-01.py\nLanguage: python\nAnalysis focus: security\nThis is chunk 1 of 10."
})

// CSV data analysis (header-preserving chunks)
Task({
  subagent_type: "swarm:rlm-data-analyzer",
  description: "Analyze data chunk",
  prompt: "Query: Analyze distribution by region\nFile: /tmp/rlm-chunks/chunk-03.csv\nThis is chunk 3 of 9.\nKey columns: region, plan, mrr"
})

// JSON analysis (schema-aware chunks)
Task({
  subagent_type: "swarm:rlm-json-analyzer",
  description: "Analyze JSON chunk",
  prompt: "Query: Report schema patterns and anomalies\nFile: /tmp/rlm-chunks/chunk-02.jsonl\nFormat: jsonl\nThis is chunk 2 of 8."
})

// General chunk analysis (logs, prose, config, other)
Task({
  subagent_type: "swarm:rlm-chunk-analyzer",
  description: "Analyze log chunk",
  prompt: "Query: What errors occurred?\nFile: /var/log/app/server.log\nStart line: 1\nEnd line: 200\nThis is chunk 1 of 10."
})

// Synthesis (higher quality)
Task({
  subagent_type: "swarm:rlm-synthesizer",
  description: "Synthesize findings",
  prompt: "Original query: What errors occurred?\n\nFindings:\n[...findings JSON...]"
})
```

**RLM agents (defined by this plugin):**
- `swarm:rlm-code-analyzer` — Haiku model, code-aware chunk analysis with scope context and analysis focus
- `swarm:rlm-data-analyzer` — Haiku model, CSV/TSV chunk analysis with column distributions and statistics
- `swarm:rlm-json-analyzer` — Haiku model, JSON/JSONL chunk analysis with schema patterns and field distributions
- `swarm:rlm-chunk-analyzer` — Haiku model, general-purpose chunk analysis for logs, prose, config, markup
- `swarm:rlm-synthesizer` — Sonnet model, aggregates findings from multiple chunk analyses into coherent reports

**Do NOT override analyst models.** Do not pass `model: "sonnet"` or `model: "opus"` in the Task tool call when spawning analyst agents. The agent frontmatter defines `model: haiku` because structured counting, frequency analysis, and JSON output are well within Haiku's capability. Overriding to a more expensive model burns 10-50x the cost per chunk with no material quality gain. Only the synthesizer uses Sonnet. Leave the `model` parameter unset — let the agent definition's default apply.

## Agent Type Naming Convention

Plugin agents use the format: `{plugin}:{agent-name}` or `{plugin}:{category}:{agent-name}`

Examples:
- `sdlc:security-reviewer`
- `feature-dev:code-reviewer`
- `refactor:architect`
- `code-simplifier:code-simplifier`

Built-in agents use simple names: `Bash`, `Explore`, `Plan`, `general-purpose`, `claude-code-guide`, `statusline-setup`.

Swarm plugin agents follow the same convention:
- `swarm:rlm-code-analyzer`
- `swarm:rlm-data-analyzer`
- `swarm:rlm-json-analyzer`
- `swarm:rlm-chunk-analyzer`
- `swarm:rlm-synthesizer`
