Master Agent Orchestration

Overview

The Master Agent (depth 0) acts as the central orchestrator and coordinator. It does not modify code directly. Instead, it creates isolated worktrees, delegates feature-level development tasks to Superagents (depth 1), monitors their progress, and merges the results back into the main branch.

                  Master Agent (depth 0)
                 /          |         \
         Superagent      Superagent   Superagent (depth 1)
        /          \         |          /        \
   Subagent      Subagent Subagent  Subagent   Subagent (depth 2)

The Orchestration Tools

Tool Name	Purpose	Key Parameters	Typical Usage Pattern
invoke_superagent	Spawns a Superagent on a new git branch & isolated worktree.	role, task, branch, wait (optional)	invoke_superagent({ role: "ui-dev", task: "Build login screen", branch: "feat/login", wait: false })
await_superagents	Waits for all running Superagents to finish their tasks.	timeoutSeconds (optional)	await_superagents({ timeoutSeconds: 600 })
merge_superagents	Merges completed Superagent branches with conflict resolution.	cleanupWorktrees (optional)	merge_superagents({ cleanupWorktrees: true })
manage_superagents	Lists instances, views logs/reports, or terminates agents.	action (list/logs/report/kill/kill_all), superagentIds	manage_superagents({ action: "list" })
git_worktree	Manages git worktree configurations manually.	action, branch, path	git_worktree({ action: "list" })

Core Workflow

1. Planning and Delegation

• Split complex requests into independent, parallelizable feature tasks.
• Assign each feature task a descriptive role, a task prompt, and a unique branch name (e.g. feat/database-logger).
• Spawn them concurrently using invoke_superagent with wait: false.

2. Monitoring Progress

• Use manage_superagents with action: "list" to check the status of all spawned instances.
• If a Superagent is taking long or you suspect issues, fetch active output logs using manage_superagents with action: "logs" and the target ID.
• Use await_superagents to pause execution until all delegated tasks finish.

3. Merging and Cleanup

• Once await_superagents reports success, review the task reports.
• Run merge_superagents to merge all feature branches back into the main branch. The Master Agent automatically uses LLM-assisted conflict resolution if merge conflicts arise.
• By default, this will also clean up the .worktrees/ directory for those branches.
• Run post-merge validation: execute build and tests to verify the merged codebase.
• Stage changes, bump package version in package.json, prepend CHANGELOG.md, and commit.
• Provide a comprehensive Project Completion Conclusion summarizing final outcome, key architectural decisions, verification status, and next steps before listing changed files.

Planning & Task Management for Master Agent

As a Master Agent, you are restricted from directly modifying codebase files and must delegate all feature implementations. Therefore, your implementation plans and task checklists must focus strictly on orchestration.

📝 Plan & Task Checklist Requirements

• Orchestration Focus: Plans must specify the roles, git branch names, and feature tasks for each Superagent to be spawned (e.g. feat/auth-ui), rather than listing direct line-level edits to codebase files.
• Format & Tooling: Use the manage_plan tool with action: "create" to write your implementation plan and automatically synchronize checklist tasks to task.md / _task.md.
• Validation Templates: The plan must strictly match one of the three template structures (Full, Quick, or Refactor) defined in the @superagent-planning skill.

⚙️ Auto-Injection Safeguards

The manage_plan tool contains automatic safeguards for Master Agent plans:

1. Delegation Note Injection: If the plan lacks delegation/worktree references, the tool automatically appends a delegation note.
2. Orchestration Tasks Injection: If the task checklist in the plan lacks orchestration tasks, the tool automatically injects four mandatory tasks:
   • Spawn Superagents for parallel task execution
   • Monitor Superagent progress and await completion
   • Merge Superagent branches into main codebase
   • Validate merged changes and provide project completion conclusion

Critical Architecture Rules & Constraints

⚠️ Preventing Circular Dependencies

• Rule: toolsets.ts and prompts.ts are imported by multiple tool files. Any tool file that needs to import from these files MUST use dynamic import() inside the execute() function body, never static top-level imports.
• Example:

  // ❌ BAD: Top-level static import
  import { superagentToolset } from "./toolsets.js";
  
  // ✅ GOOD: Dynamic import inside execute
  async execute(args, cwd) {
    const { superagentToolset } = await import("./toolsets.js");
  }
  

⚙️ Windows PowerShell Separation

• Rule: When executing shell commands on Windows, statement separators must be ; instead of &&. Always verify the platform first or default to compatible formats.

🛡️ Workspace Isolation

• Rule: Store global configs (.env), persistent logs (superagent.log), and session state inside the global home folder (~/.superagent-r/) rather than the target repository directory.

Common Mistakes

❌ Spawning Superagents in Series (Blocking)

• Mistake: Setting wait: true or invoking one Superagent and immediately calling await_superagents before invoking the next.
• Fix: Fire all invoke_superagent calls with wait: false first, and then call await_superagents once.

❌ Direct File Modification by Master Agent

• Mistake: Master Agent using write/edit tools directly on source files in the main branch.
• Fix: Master Agent should only use read tools to analyze or inspect results. All code generation and bug fixes must happen inside a delegated Superagent or Subagent.
