--- name: flow-swarm version: 2.1.1 description: > Multi-agent swarm orchestration via RuFlo + Claude Code. Turns single coding sessions into coordinated agent teams (architect/coder/tester/reviewer). Proven on 7 consecutive production runs generating 430+ tests across a 50K+ line Elixir codebase with 83% zero-iteration success rate. Features 150+ MCP tools for inter-agent coordination, persistent cross-run memory (sql.js + HNSW vectors), task tracking, file claim locks, and session persistence. Includes battle-tested prompt templates for test generation, feature builds, refactors, security audits, and quality loops. Setup script with 8-point verification. Works with any language, any codebase. NOT for one-liner edits or read-only tasks. Triggers: "swarm this", "flow swarm", "use the swarm", "flowswarm". --- # FlowSwarm v2.1 Multi-agent swarm orchestration for Claude Code via RuFlo. One prompt, coordinated agents, production results. ## What Changed in v2.1 Critical fix: **MCP tools were disabled** (`autoStart: false`). This prevented Claude Code from calling `mcp__claude-flow__swarm_init`, `memory_store`, `agent_spawn`, etc. during every swarm run we'd done so far. Fixed. Also fixed: `--print` mode **does not** auto-discover `.mcp.json`. You must pass `--mcp-config .mcp.json` explicitly. | Change | Why | |---|---| | `autoStart: true` in `.mcp.json` | Was `false` — all 150+ MCP tools were disabled in every prior run | | `--mcp-config .mcp.json` flag added to exec pattern | `--print` doesn't auto-load project MCP config | | MCP tool reference table added | 150+ tools now documented: swarm_init, agent_spawn, memory_store, etc. | | Prompt templates updated to call MCP tools | Without explicit instructions, Claude may not use them | | Setup script auto-fixes autoStart | `ruflo init` defaults to false; setup script corrects it | ## What Changed in v2.0 v1.0 was theory. v2.0 is battle-tested across 5 production runs (355 tests, 5/5 green, 4/5 zero-iteration). | Change | Why | |---|---| | Tiered task routing replaces one-size-fits-all | Pure-data modules don't need GenServer test isolation advice | | Target selection protocol added | Picking the RIGHT module matters more than swarm config | | Pre-flight context injection | Feeding the swarm grep output of public functions = dramatically better coverage | | Daemon reality check | Workers timeout/fail often (20-50% success); swarm value comes from prompt orchestration, not daemon workers | | Removed WASM Booster claims | Never observed in practice; hooks + prompt patterns drive all real value | | Real performance data | Actual timing, test counts, iteration rates from production runs | ## Architecture Two layers working together: **Layer 1: MCP Tools (150+ tools via @claude-flow/cli)** When `autoStart: true` in `.mcp.json`, Claude Code gets access to real coordination tools: - `swarm_init` — creates swarm with topology, persists to `.claude-flow/swarm/swarm-state.json` - `agent_spawn` — registers agents with model routing (haiku/sonnet/opus/inherit) - `memory_store` / `memory_search` — sql.js + HNSW vector embeddings for semantic recall - `task_create` / `task_complete` — tracks task state with assignment - `session_save` / `session_restore` — persists session state between runs - `claims_claim` / `claims_release` — prevents agents from editing same files - `coordination_consensus` — multi-agent agreement on decisions **Layer 2: Prompt Orchestration (our FlowSwarm patterns)** The SWARM MODE prefix causes Claude Code to think in roles (architect/coder/reviewer). Combined with pre-flight context injection (grepping public APIs), this produces 80% zero-iteration success. **Both layers matter.** v1.0 had Layer 2 only (autoStart was false, MCP tools never loaded). v2.0 enables both. ``` OpenClaw → exec (background) → Claude Code ↓ MCP Server starts (autoStart: true) 150+ tools available via @claude-flow/cli ↓ SWARM MODE prompt → swarm_init tool called agent_spawn × N → task_create → execute ↓ memory_store (findings) → task_complete ↓ Output + persisted state ``` ## Prerequisites ```bash ruflo --version # 3.5.x+ claude --version # Claude Code CLI ``` ## Setup (One-Time Per Machine) ```bash # Full setup: install RuFlo + register MCP + init project ./scripts/setup-flow-swarm.sh /path/to/project # Verify ./scripts/setup-flow-swarm.sh --verify /path/to/project ``` Or manually: ```bash npm install -g ruflo@latest claude mcp add ruflo -- npx -y ruflo@latest mcp start cd /path/to/project && ruflo init && ruflo memory init && ruflo daemon start ``` ## CRITICAL: Enable MCP Server After `ruflo init`, the `.mcp.json` file defaults to `autoStart: false`. This disables ALL 150+ MCP tools during Claude Code sessions. Fix it: ```bash # Check current state python3 -c "import json; d=json.load(open('.mcp.json')); print('autoStart:', d['mcpServers']['claude-flow'].get('autoStart'))" # Enable (REQUIRED for full swarm functionality) python3 -c " import json with open('.mcp.json') as f: d = json.load(f) d['mcpServers']['claude-flow']['autoStart'] = True with open('.mcp.json', 'w') as f: json.dump(d, f, indent=2) print('MCP autoStart enabled') " ``` Without this, Claude Code runs without swarm tools. The prompt patterns still work (v1.0 proved this), but you lose: persistent swarm state, agent memory, task tracking, session persistence, and inter-agent coordination. ## The FlowSwarm Protocol (3 Steps) ### Step 1: Select Your Target **This is the highest-leverage decision.** Pick wrong and you waste a swarm run. Best targets (in order): 1. **Large modules with zero tests** — highest ROI, swarm excels here 2. **Pure data/logic modules** — no IO mocking needed, near-100% first-pass success 3. **Modules with thin test coverage** — swarm fills gaps the original author skipped 4. **Feature builds with clear specs** — architect/coder/reviewer shines on greenfield Find targets fast: ```bash # List untested modules by size (biggest = best target) for f in lib/**/*.ex; do base=$(basename "$f" .ex) count=$(find test/ -name "${base}_test.exs" 2>/dev/null | wc -l | tr -d ' ') [ "$count" = "0" ] && echo "$(wc -l < "$f")L $f" done | sort -rn | head -10 ``` ### Step 2: Build the Prompt (Context-Rich) The secret sauce: **feed the swarm a pre-flight scan** of the module. Don't just say "test this file" — tell it exactly what functions exist, what patterns the project uses, what edge cases matter. ```bash # Pre-flight: scan public API grep -n "^ def " lib/your_module.ex # Pre-flight: check existing test patterns head -30 test/some_existing_test.exs ``` Then build the prompt with that intel baked in. ### Step 3: Launch and Verify ```bash # Launch (ALWAYS background, NEVER nohup) exec( command='cd /project && claude --permission-mode bypassPermissions --mcp-config .mcp.json --print "SWARM MODE: ... TASK: ..."', background=True, timeout=300 ) # Poll for completion process(action="poll", sessionId="xxx", timeout=120000) # Verify the output actually compiles/passes mix test test/path/to/new_test.exs ``` **Critical exec rules:** - `--print` buffers ALL output until exit. Use `background: true` + poll. - NEVER use `nohup` — Node.js stdout capture breaks silently (empty files). - Timeout 300s minimum for complex tasks. Simple test gen: 60-120s. - Always run `mix test` (or equivalent) on swarm output before committing. ## Prompt Templates (Battle-Tested) ### Test Generation — Pure Data Module **Proven: 147/147, 66/66, 41/41 zero-iteration** Best for: static catalogs, type definitions, translation modules, config builders. ``` SWARM MODE: Initialize hierarchical swarm with MCP tools. COORDINATION: 1. Call swarm_init with topology "hierarchical", maxAgents 4, strategy "specialized" 2. Call agent_spawn for: architect (analyze module), coder (write tests), reviewer (verify) 3. Call task_create for the test generation task 4. After completion: call memory_store with key findings and task_complete TASK: Write comprehensive ExUnit tests for [MODULE_PATH] ([LINE_COUNT] lines, [DESCRIPTION]). Public API: [PASTE grep -n "^ def " output here] Key data to validate: - [List specific assertions: required struct keys, value ranges, URL formats, etc.] - [List known edge cases: unknown inputs, nil, empty string, integer where string expected] Requirements: - File: test/[matching_path]_test.exs - Use async: true (pure functions, no state) - Group tests by function (describe blocks) - Test ALL variants, not just a sample (e.g., all 8 hotels, not just 2) - Include edge cases: nil input, empty string, unknown keys - Do NOT modify any source files When done: call memory_store with test count + key findings, then output results. ``` ### Test Generation — GenServer / Stateful Module **Proven: 43/43, required 3 iterations (test isolation)** ``` SWARM MODE: Initialize hierarchical swarm with MCP tools. COORDINATION: 1. Call swarm_init with topology "hierarchical", maxAgents 4, strategy "specialized" 2. Call agent_spawn for: architect (analyze GenServer behavior), coder (write tests), reviewer (verify) 3. Call task_create for the test generation task 4. After each iteration: call memory_store with what failed and why 5. After completion: call task_complete with final results TASK: Write comprehensive ExUnit tests for [MODULE_PATH] ([LINE_COUNT] lines, GenServer). Public API: [PASTE grep output] CRITICAL — Test Isolation for GenServers: - The module registers as a named process (__MODULE__). It's already supervised globally. - Do NOT use start_supervised! — it conflicts with the app-supervised instance. - Pattern: stop the global instance, restart with test config, re-stop at end. - OR: if start_link accepts a name: option, use unique names per test. - async: false for GenServer tests that touch global state. Requirements: - Test GenServer lifecycle (init, handle_call, handle_cast, handle_info) - Test crash recovery: missing catch-all handlers are REAL BUGS worth flagging - Test state transitions and side effects - Do NOT modify any source files ``` ### Test Generation — Module with External Dependencies ``` SWARM MODE: Initialize hierarchical swarm (maxAgents 4, strategy specialized). Spawn: architect (analyze deps + plan mocks), coder (write tests), reviewer (verify coverage). TASK: Write comprehensive ExUnit tests for [MODULE_PATH]. This module depends on: [LIST DEPENDENCIES] Mock strategy: [Mox / manual mock / test config override] Reference existing mocks in test/support/ if any. Requirements: - Mock all external calls (HTTP, DB, external services) - Test happy path AND error paths (timeouts, 4xx, 5xx, malformed responses) - async: true if using Mox with allowances - Do NOT modify source files ``` ### Feature Build (Greenfield) ``` SWARM MODE: Initialize hierarchical swarm (maxAgents 6, strategy specialized). Spawn: architect (plan structure), coder (implement), tester (tests), reviewer (quality). Architect plans FIRST. Coder implements. Tester validates. Reviewer catches issues. TASK: [Feature description with clear acceptance criteria] Architecture constraints: - [List patterns to follow from existing codebase] - [List modules/files to reference for conventions] HARD LIMIT: Maximum 5 iterations if quality loop needed. ``` ### Refactor (Anti-Drift) ``` SWARM MODE: Initialize anti-drift hierarchical swarm (maxAgents 4). Spawn: architect (plan + checkpoint), coder (execute), reviewer (validate each step). ANTI-DRIFT RULES: - Architect creates numbered plan before ANY code is written - Coder implements ONE step at a time - Reviewer validates EACH step before proceeding - If reviewer rejects twice: STOP and report - Checkpoint state after each successful step TASK: [Refactor description] HARD LIMIT: Maximum 8 iterations. ``` ### Security Audit ``` SWARM MODE: Security-focused hierarchical swarm (maxAgents 5, strategy specialized). Spawn: security-architect (threat model), auditor (scan), coder (fix), tester (verify). TASK: Security audit of [scope]. Checklist: - [ ] Dependency vulnerabilities (mix audit / npm audit) - [ ] Hardcoded secrets in source - [ ] Injection vectors (SQL, XSS, command) - [ ] Auth/authz bypass paths - [ ] GenServer catch-all handlers (handle_info, handle_cast) — these are REAL BUGS - [ ] Error messages leaking internal state - [ ] Rate limiting gaps - [ ] CORS/CSP headers Output: findings table with severity, file, line, fix. HARD LIMIT: Maximum 5 iterations. ``` ### Quality Loop (Ralph-Style) ``` SWARM MODE: Initialize ring swarm (maxAgents 4, strategy adaptive). Spawn: coder, tester, reviewer, coordinator. HARD LIMIT: Maximum 10 iterations. TASK: Iterate on [target] until [score threshold]. Per iteration: 1. Coder fixes based on reviewer feedback 2. Tester runs full suite, reports pass/fail count 3. Reviewer scores against rubric 4. Score >= threshold → STOP, report final score 5. Iteration == 10 → STOP regardless, report score and remaining gaps ``` ## MCP Tools Reference (Available When autoStart: true) These tools become available to Claude Code during swarm sessions. Include instructions to USE them in your prompts. ### Core Swarm (must-use) | Tool | Purpose | |---|---| | `swarm_init` | Create swarm with topology + strategy. Persists to `.claude-flow/swarm/` | | `swarm_status` | Check swarm health mid-run | | `swarm_shutdown` | Clean shutdown with state persistence | | `agent_spawn` | Register agents with model routing (haiku/sonnet/opus) | | `agent_status` | Check individual agent state | | `memory_store` | Persist findings to sql.js + HNSW (semantic search) | | `memory_search` | Retrieve relevant context from prior runs | | `task_create` | Track task with assignment + status | | `task_complete` | Mark task done with summary | ### Coordination (high-value for complex tasks) | Tool | Purpose | |---|---| | `session_save` | Save session state between runs | | `session_restore` | Resume from prior session | | `claims_claim` | Lock a file/resource (prevents agent conflicts) | | `claims_release` | Release lock | | `coordination_consensus` | Multi-agent agreement | | `coordination_sync` | Synchronize agent state | ### Analysis (useful for reviews) | Tool | Purpose | |---|---| | `analyze_diff` | Review code changes | | `analyze_diff_risk` | Assess risk of changes | | `performance_report` | Bottleneck detection | ### Why This Matters Without `autoStart: true`, Claude Code has ZERO access to these tools. It runs on prompt intelligence alone (which works, as v1.0 proved). With them enabled, the swarm can: - **Persist memories between runs** — learn from prior sessions - **Track tasks formally** — not just in-context reasoning - **Coordinate agents** — prevent file conflicts, reach consensus - **Route by model** — use haiku for simple subtasks, opus for architecture ## Swarm Topologies | Topology | When | Track Record | |---|---|---| | `hierarchical` | Test gen, features, refactors | 5/5 green tonight | | `ring` | Quality loops, pipelines | Proven in Ralph loops | | `mesh` | Research, exploration | Untested in production | | `star` | Simple delegation | Untested in production | **Default: `hierarchical`.** It has the strongest anti-drift properties and all production wins used it. ## Performance Data (Real, Not Theoretical) ### Test Generation Runs (March 23, 2026) | Module | Lines | Tests | Time | Iterations | Result | |---|---|---|---|---|---| | AssetHealthCheck (GenServer) | 288 | 43 | ~120s | 3 | 43/43 ✅ + found 2 real bugs | | WidgetHotelAssets (data) | 2,017 | 147 | ~90s | 0 | 147/147 ✅ | | SquadBuilder (config builder) | 889 | 58 | ~90s | 0 | 58/58 ✅ | | I18n (translations) | 272 | 41 | ~60s | 0 | 41/41 ✅ | | TravelClick Types (structs) | 637 | 66 | ~90s | 0 | 66/66 ✅ | **Totals:** 355 new tests, 5/5 modules green, 4/5 zero-iteration (80%) ### Key Observations - **Pure data modules**: near-100% first-pass success. No iteration needed. - **GenServer modules**: expect 2-3 iterations for test isolation issues. - **Real bugs found**: 2 missing catch-all handlers (handle_cast, handle_info) — production-grade findings. - **Data quality issues found**: 1 (duplicate image URLs across hotel rooms). - **Execution time**: 60-120s per module regardless of size (bottleneck is Claude Code `--print` buffering, not swarm complexity). ### Daemon Worker Reality Check | Worker | Success Rate | Notes | |---|---|---| | map | 100% | Fast (1ms), just indexes project structure | | consolidate | 100% | Fast (9ms), memory compaction | | audit | 20% | Timeouts at 300s, falls back to local mode | | optimize | 33% | Timeouts, deferred on high CPU load | | testgaps | 50% | Deferred on high CPU load | | predict | 0% | Disabled by default | | document | 0% | Disabled by default | **Takeaway:** Don't rely on daemon workers for task quality. The prompt pattern does the heavy lifting. Daemon adds marginal background value (map + consolidate work; audit/optimize are unreliable). ## Parallel Swarm Runs You can run multiple swarms simultaneously on different modules. Each gets its own exec session: ```python # Launch 2 parallel swarms exec(command='cd /project && claude --mcp-config .mcp.json --print "SWARM: ... TASK: test module_a"', background=True) exec(command='cd /project && claude --mcp-config .mcp.json --print "SWARM: ... TASK: test module_b"', background=True) # Poll both process(action="poll", sessionId="session-a", timeout=120000) process(action="poll", sessionId="session-b", timeout=120000) ``` **Observed:** 2 parallel swarms work cleanly. 3+ may cause CPU load deferrals on daemon workers (irrelevant for prompt-driven value). ## Self-Improvement Protocol FlowSwarm can analyze and improve itself: ``` SWARM MODE: Initialize meta-analysis hierarchical swarm (maxAgents 4). Spawn: architect (analyze skill files), analyst (review production data), coder (rewrite), reviewer (validate). TASK: Analyze the FlowSwarm skill at [path] against production run data. Review: what worked, what failed, what's missing. Generate v[N+1]. ``` ## Troubleshooting **No output from Claude Code:** `--print` buffers until completion. Use `background: true` on exec, poll with generous timeout. Never use `nohup`. **Swarm didn't fire:** 1. Check `.claude/settings.json` has hooks 2. Run `ruflo doctor` 3. Verify MCP: `claude mcp list | grep ruflo` 4. Restart: `ruflo daemon stop && ruflo daemon start` **GenServer test isolation failures:** The global supervised instance conflicts with test instances. Solutions: - Stop global, restart for test, cleanup after - Use unique names: `name: :"test_#{System.unique_integer()}"` - Set `async: false` for stateful tests **Daemon workers timing out:** Normal. Workers like `audit` and `optimize` timeout at 300s regularly (20-33% success rate). The swarm's value comes from prompt orchestration, not daemon workers. Ignore worker failures unless you specifically need their output. **Memory shows 0 entries:** In v1.0 (autoStart: false), the MCP server never started so memory_store was never called. With v2.0 (autoStart: true), Claude Code can call memory_store directly. Check after a run: ```bash ruflo memory stats ruflo memory search -q "test results" ``` **CPU load deferrals:** Workers defer when system CPU > 8. This is protective. During active swarm runs, expect deferrals. Workers catch up when CPU drops. ## Files ``` skills/flow-swarm/ ├── SKILL.md # This file (v2.0) ├── scripts/ │ └── setup-flow-swarm.sh # Install + init + verify └── references/ └── template-examples.md # Extended templates with context ``` ## Changelog ### v2.1.0 (2026-03-23) - **CRITICAL FIX:** Enabled MCP autoStart (was false, disabling ALL 150+ swarm tools) - Added MCP tool reference table (swarm_init, agent_spawn, memory_store, etc.) - Updated prompt templates to instruct Claude Code to USE MCP tools - Setup script now auto-fixes autoStart: false → true - Verify mode checks autoStart status - Documented full MCP tool inventory (150+ tools across 18 categories) - Root cause of "memory shows 0 entries" identified: MCP server wasn't running ### v2.0.0 (2026-03-23) - Complete rewrite based on 5 production swarm runs (355 tests generated) - Added tiered prompt templates (pure-data vs GenServer vs external deps) - Added target selection protocol + --targets script flag - Added pre-flight context injection pattern - Added real performance data table with actual timing and iteration counts - Added parallel swarm run documentation - Added daemon worker reality check (success rates, what to ignore) - Added self-improvement protocol - Removed unverified WASM Booster performance claims - Fixed: documented that `--print` mode doesn't persist swarm memories ### v1.0.0 (2026-03-23) - Initial release based on first swarm run (AssetHealthCheck)
