Multi-Agent Orchestration

Meta-orchestration patterns mined from 597+ real agent dispatches across production codebases. This skill tells you WHICH strategy to use, HOW to structure prompts, and WHEN to use background vs foreground.

Core principle: Choose the right orchestration strategy for the work, partition agents by independence, inject context to enable parallelism, and adapt review overhead to trust level.

Strategy 1: Research Swarm

Mass-deploy background agents to build a knowledge corpus. Each agent researches one topic and writes one markdown document. Zero dependencies between agents.

When to Use

• Kicking off a new project (need SOTA for all technologies)
• Building a skill/plugin (need comprehensive domain knowledge)
• Technology evaluation (compare multiple options in parallel)

The Pattern

Phase 1: Deploy research army (ALL BACKGROUND)
    Wave 1 (10-20 agents): Core technology research
    Wave 2 (10-20 agents): Specialized topics, integrations
    Wave 3 (5-10 agents): Gap-filling based on early results

Phase 2: Monitor and supplement
    - Check completed docs as they arrive
    - Identify gaps, deploy targeted follow-up agents
    - Read completed research to inform remaining dispatches

Phase 3: Synthesize
    - Read all research docs (foreground)
    - Create architecture plans, design docs
    - Use Plan agent to synthesize findings

Prompt Template: Research Agent

Research [TECHNOLOGY] for [PROJECT]'s [USE CASE].

Create a comprehensive research doc at [OUTPUT_PATH]/[filename].md covering:

1. Latest [TECH] version and features (search "[TECH] 2026" or "[TECH] latest")
2. [Specific feature relevant to project]
3. [Another relevant feature]
4. [Integration patterns with other stack components]
5. [Performance characteristics]
6. [Known gotchas and limitations]
7. [Best practices for production use]
8. [Code examples for key patterns]

Include code examples where possible. Use WebSearch and WebFetch to get current docs.

Key rules:

• Every agent gets an explicit output file path (no ambiguity)
• Include search hints: "search [TECH] 2026" (agents need recency guidance)
• Numbered coverage list (8-12 items) scopes the research precisely
• ALL agents run in background -- no dependencies between research topics

Dispatch Cadence

• 3-4 seconds between agent dispatches
• Group into thematic waves of 10-20 agents
• 15-25 minute gaps between waves for gap analysis

Strategy 2: Epic Parallel Build

Deploy background agents to implement independent features/epics simultaneously. Each agent builds one feature in its own directory/module. No two agents touch the same files.

When to Use

• Implementation plan with 10+ independent tasks
• Monorepo with isolated packages/modules
• Sprint backlog with non-overlapping features

The Pattern

Phase 1: Scout (FOREGROUND)
    - Deploy one Explore agent to map the codebase
    - Identify dependency chains and independent workstreams
    - Group tasks by subsystem to prevent file conflicts

Phase 2: Deploy build army (ALL BACKGROUND)
    Wave 1: Infrastructure/foundation (Redis, DB, auth)
    Wave 2: Backend APIs (each in own module directory)
    Wave 3: Frontend pages (each in own route directory)
    Wave 4: Integrations (MCP servers, external services)
    Wave 5: DevOps (CI, Docker, deployment)
    Wave 6: Bug fixes from review findings

Phase 3: Monitor and coordinate
    - Check git status for completed commits
    - Handle git index.lock contention (expected with 30+ agents)
    - Deploy remaining tasks as agents complete
    - Track via Sibyl tasks or TodoWrite

Phase 4: Review and harden (FOREGROUND)
    - Run `cross-model-review` on completed work
    - Dispatch fix agents for critical findings
    - Integration testing

Prompt Template: Feature Build Agent

**Task: [DESCRIPTIVE TITLE]** (task\_[ID])

Work in /path/to/project/[SPECIFIC_DIRECTORY]

## Context

[What already exists. Reference specific files, patterns, infrastructure.]
[e.g., "Redis is available at `app.state.redis`", "Follow pattern from `src/auth/`"]

## Your Job

1. Create `src/path/to/module/` with:
   - `file.py` -- [Description]
   - `routes.py` -- [Description]
   - `models.py` -- [Schema definitions]

2. Implementation requirements:
   [Detailed spec with code snippets, Pydantic models, API contracts]

3. Tests:
   - Create `tests/test_module.py`
   - Cover: [specific test scenarios]

4. Integration:
   - Wire into [main app entry point]
   - Register routes at [path]

## Git

Commit with message: "feat([module]): [description]"
Only stage files YOU created. Check `git status` before committing.
Do NOT stage files from other agents.

Key rules:

• Every agent gets its own directory scope -- NO OVERLAP
• Provide existing patterns to follow ("Follow pattern from X")
• Include infrastructure context ("Redis available at X")
• Explicit git hygiene instructions (critical with 30+ parallel agents)
• Task IDs for traceability

Git Coordination for Parallel Agents

When running 10+ agents concurrently:

1. Expect index.lock contention -- agents will retry automatically
2. Each agent commits only its own files -- prompt must say this explicitly
3. No agent should run git add . -- only specific files
4. Monitor with git log --oneline -20 periodically
5. No agent should push -- orchestrator handles push after integration

Strategy 3: Sequential Pipeline

Execute dependent tasks one at a time with review gates. Each task builds on the previous task's output.

When to Use

• Tasks that modify shared files
• Integration boundary work (JNI bridges, auth chains)
• Review-then-fix cycles where each fix depends on review findings
• Complex features where implementation order matters

The Pattern

For each task:
    1. Dispatch implementer (FOREGROUND)
    2. Dispatch spec reviewer (FOREGROUND)
    3. Dispatch code quality reviewer (FOREGROUND)
    4. Fix any issues found
    5. Move to next task

Trust Gradient (adapt over time):
    Early tasks:  Implement -> Spec Review -> Code Review (full ceremony)
    Middle tasks: Implement -> Spec Review (lighter)
    Late tasks:   Implement only (pattern proven, high confidence)

Trust Gradient

As the session progresses and patterns prove reliable, progressively lighten review overhead:

This is NOT cutting corners -- it's earned confidence. If a late task deviates from the pattern, escalate back to full ceremony.

Strategy 4: Parallel Sweep

Apply the same transformation across partitioned areas of the codebase. Every agent does the same TYPE of work but on different FILES.

When to Use

• Lint/format fixes across modules
• Type annotation additions across packages
• Test writing for multiple modules
• Documentation updates across components
• UI polish across pages

The Pattern

Phase 1: Analyze the scope
    - Run the tool (ruff, ty, etc.) to get full issue list
    - Auto-fix what you can
    - Group remaining issues by module/directory

Phase 2: Fan-out fix agents (4-10 agents)
    - One agent per module/directory
    - Each gets: issue count by category, domain-specific guidance
    - All foreground (need to verify each completes)

Phase 3: Verify and repeat
    - Run the tool again to check remaining issues
    - If issues remain, dispatch another wave
    - Repeat until clean

Prompt Template: Module Fix Agent

Fix all [TOOL] issues in the [MODULE_NAME] directory ([PATH]).

Current issues ([COUNT] total):

- [RULE_CODE]: [description] ([count]) -- [domain-specific fix guidance]
- [RULE_CODE]: [description] ([count]) -- [domain-specific fix guidance]

Run `[TOOL_COMMAND] [PATH]` to see exact issues.

IMPORTANT for [DOMAIN] code:
[Domain-specific guidance, e.g., "GTK imports need GI.require_version() before gi.repository imports"]

After fixing, run `[TOOL_COMMAND] [PATH]` to verify zero issues remain.

Key rules:

• Provide issue counts by category (not just "fix everything")
• Include domain-specific guidance (agents need to know WHY patterns exist)
• Partition by directory to prevent overlap
• Run in waves: fix -> verify -> fix remaining -> verify

Strategy 5: Multi-Dimensional Audit

Deploy multiple reviewers to examine the same code from different angles simultaneously. Each reviewer has a different focus lens.

When to Use

• Major feature complete, need comprehensive review
• Pre-release quality gate
• Security audit
• Performance assessment

The Pattern

Dispatch 6 parallel reviewers (ALL FOREGROUND):
    1. Code quality & safety reviewer
    2. Integration correctness reviewer
    3. Spec completeness reviewer
    4. Test coverage reviewer
    5. Performance analyst
    6. Security auditor

Wait for all to complete, then:
    - Synthesize findings into prioritized action list
    - Dispatch targeted fix agents for critical issues
    - Re-review only the dimensions that had findings

Prompt Template: Dimension Reviewer

[DIMENSION] review of [COMPONENT] implementation.

**Files to review:**

- [file1.ext]
- [file2.ext]
- [file3.ext]

**Analyze:**

1. [Specific question for this dimension]
2. [Specific question for this dimension]
3. [Specific question for this dimension]

**Report format:**

- Findings: numbered list with severity (Critical/Important/Minor)
- Assessment: Approved / Needs Changes
- Recommendations: prioritized action items

Strategy 6: Full Lifecycle

For greenfield projects, combine all strategies in sequence:

Session 1: RESEARCH (Research Swarm)
    -> 30-60 background agents build knowledge corpus
    -> Architecture planning agents synthesize findings
    -> Output: docs/research/*.md + docs/plans/*.md

Session 2: BUILD (Epic Parallel Build)
    -> Scout agent maps what exists
    -> 30-60 background agents build features by epic
    -> Monitor, handle git contention, track completions
    -> Output: working codebase with commits

Session 3: ITERATE (Build-Review-Fix Pipeline)
    -> Code review agents assess work
    -> Fix agents address findings
    -> Deep audit agents (foreground) assess each subsystem
    -> Output: quality-assessed codebase

Session 4: HARDEN (Sequential Pipeline)
    -> Integration boundary reviews (foreground, sequential)
    -> Security fixes, race condition fixes
    -> Test infrastructure setup
    -> Output: production-ready codebase

Session 5: CONSOLIDATE (Dream)
    -> Capture durable patterns, gotchas, and architecture decisions
    -> Link learnings back to project context in Sibyl
    -> Output: updated knowledge graph for future sessions

Each session shifts orchestration strategy to match the work's nature. Parallel when possible, sequential when required.

    "Does next task depend on this task's files?" -> "FOREGROUND (parallel)" [label="no - different modules"];
}

Rules observed from 597+ dispatches:

• Research agents with no immediate dependency -> BACKGROUND (100% of the time)
• Code-writing agents -> FOREGROUND (even if parallel)
• Review/validation gates -> FOREGROUND (blocks pipeline)
• Sequential dependencies -> FOREGROUND, one at a time

Prompt Engineering Patterns

Pattern A: Role + Mission + Structure (Research)

You are researching [DOMAIN] to create comprehensive documentation for [PROJECT].

Your mission: Create an exhaustive reference document covering ALL [TOPIC] capabilities.

Cover these areas in depth:

1. **[Category]** -- specific items
2. **[Category]** -- specific items
   ...

Use WebSearch and WebFetch to find blog posts, GitHub repos, and official docs.

Pattern B: Task + Context + Files + Spec (Feature Build)

**Task: [TITLE]** (task\_[ID])

Work in /absolute/path/to/[directory]

## Context

[What exists, what to read, what infrastructure is available]

## Your Job

1. Create `path/to/file` with [description]
2. [Detailed implementation spec]
3. [Test requirements]
4. [Integration requirements]

## Git

Commit with: "feat([scope]): [message]"
Only stage YOUR files.

Pattern C: Review + Verify + Report (Audit)

Comprehensive audit of [SCOPE] for [DIMENSION].

Look for:

1. [Specific thing #1]
2. [Specific thing #2]
   ...
3. [Specific thing #10]

[Scope boundaries -- which directories/files]

Report format:

- Findings: numbered with severity
- Assessment: Pass / Needs Work
- Action items: prioritized

Pattern D: Issue + Location + Fix (Bug Fix)

**Task:** Fix [ISSUE] -- [SEVERITY]

**Problem:** [Description with file:line references]
**Location:** [Exact file path]

**Fix Required:**

1. [Specific change]
2. [Specific change]

**Verify:**

1. Run [command] to confirm fix
2. Run tests: [test command]

Context Injection: The Parallelism Enabler

Agents can work independently BECAUSE the orchestrator pre-loads them with all context they need. Without this, agents would need to explore first, serializing the work.

Always inject:

• Absolute file paths (never relative)
• Existing patterns to follow ("Follow pattern from src/auth/jwt.py")
• Available infrastructure ("Redis at app.state.redis")
• Design language/conventions ("SilkCircuit Neon palette")
• Tool usage hints ("Use WebSearch to find...")
• Git instructions ("Only stage YOUR files")

For parallel agents, duplicate shared context:

• Copy the same context block into each agent's prompt
• Explicit exclusion notes ("11-Sibyl is handled by another agent")
• Shared utilities described identically

Monitoring Parallel Agents

When running 10+ background agents:

1. Check periodically -- git log --oneline -20 for commits
2. Read output files -- tail the agent output files for progress
3. Track completions -- Use Sibyl tasks or TodoWrite
4. Deploy gap-fillers -- As early agents complete, identify missing work
5. Handle contention -- git index.lock is expected, agents retry automatically

Status Report Template

## Agent Swarm Status

**[N] agents deployed** | **[M] completed** | **[P] in progress**

### Completed:
- [Agent description] -- [Key result]
- [Agent description] -- [Key result]

### In Progress:
- [Agent description] -- [Status]

### Gaps Identified:
- [Missing area] -- deploying follow-up agent

Anti-Patterns

Hyperskills Integration

What This Skill is NOT

• Not permission to spawn agents when the host environment forbids it.
• Not a replacement for planning; orchestration executes a task graph.
• Not useful for tiny changes that one agent can finish faster directly.
• Not a way around file ownership; overlapping edits still need sequencing.
