Claude Conductor
An autonomous pipeline orchestrator for Claude Code
Claude Conductor spawns and manages iterative Claude Code sessions to autonomously build complex software projects. It uses a blackboard architecture with schema-driven task decomposition, allowing Claude to break down large tasks into smaller subtasks and execute them sequentially without human intervention.

Execution Flow
Prepare Context
whiteboard/tasks_current.json
framework/schema_registry.json
whiteboard/current_context.json
Spawn Claude - Launches a fresh Claude Code instance (terminal or headless) with the context piped as a prompt. Uses --dangerously-skip-permissions for full autonomy.
Monitor Completion - Watches for the three required output files in /output/. Times out after configurable duration.
Post-Process - Validates outputs, archives to iteration_log/, updates task status, and merges any new subtasks into the task queue.
Loop or Terminate - If next_tasks.json contains subtasks, they're added to the queue and the loop continues. If empty ([]) or max depth reached, the component is complete.

Schema Registry Define your project's components and their contracts in framework/schema_registry.json:
{
"version": 1,
"project": "my_project",
"components": {
"DataFetcher": {
"inputs": {
"urls": { "type": "array", "items": "string" }
},
"outputs": {
"data": { "type": "array", "items": "object" }
},
"error_states": ["network_error", "parse_error"],
"description": "Fetches and parses data from URLs"
},
"DataProcessor": {
"inputs": {
"data": { "type": "array", "source": "DataFetcher" }
},
"outputs": {
"processed": { "type": "array" }
}
}
},
"pipeline_order": ["DataFetcher", "DataProcessor"]
}
Invariants Define project rules in framework/invariants.md:
Context budget limits (tokens per iteration)
Max decomposition depth
Required output files
Project-specific constraints
Usage
Quick Start # 1. Clone the repo
git clone https://github.com/yourusername/claude-conductor.git
cd claude-conductor
# 2. Configure your project
# Edit framework/schema_registry.json with your components
# Edit framework/invariants.md with your rules
# 3. Run autonomously
./run_autonomous.sh
Running Modes Foreground (visible terminal):
./run_autonomous.sh --background
# Monitor with: tail -f whiteboard/autonomous_log.txt
./run_iteration.sh 1 # Run iteration 1 with terminal
./run_iteration.sh 1 --headless # Run iteration 1 headless
from orchestrator.orchestrator import Orchestrator
orch = Orchestrator(
max_depth=5,
timeout=300,
cooldown_seconds=30
)
orch.run(start_iteration=1)
Configuration
Orchestrator Parameters | Parameter | Default | Description |
|-----------|---------|-------------|
| max_depth | 5 | Maximum task decomposition levels |
| timeout | 300 | Seconds to wait for Claude output |
| cooldown_seconds | 30 | Pause between iterations |
| max_retries | 2 | Retries before human flag |
Required Outputs Each iteration must produce three files in /output/:
implementation.pyschema_update.jsonnext_tasks.json[] if complete
Design Principles
Why Sequential, Not Parallel? Claude Conductor intentionally runs one Claude instance at a time:
Context isolation - Each iteration starts fresh, preventing context pollutionDeterministic execution - Easier to debug and reproduceResource efficiency - Avoids API rate limits and token costsDependency ordering - Later tasks can depend on earlier outputs
Blackboard Architecture The whiteboard/ directory acts as a shared blackboard:
Tasks read their context from the blackboard
Tasks write their outputs back
The orchestrator manages state transitions
No direct communication between Claude instances
Token Budget Management Each iteration receives a fixed context budget (~6000 tokens):
Invariants: ~500 tokens
Schema: ~200 tokens
Current task: ~800 tokens
Buffer: ~500 tokens
Working space: ~4000 tokens
This prevents context overflow and keeps iterations focused.
Comparison to Other Approaches | Feature | Claude Conductor | AutoGPT | LangChain Agents |
|---------|-----------------|---------|------------------|
| Execution | Sequential | Sequential | Configurable |
| Context | Fresh each iteration | Accumulated | Accumulated |
| Schema validation | Strong (JSON) | Weak | Moderate |
| Task decomposition | Structured (5 levels) | Ad-hoc | Ad-hoc |
| Process isolation | Full (new process) | Same process | Same process |
Limitations
macOS/Linux only - Terminal spawning uses platform-specific APIsClaude Code required - Depends on the Claude Code CLISequential execution - No parallelism (by design)No inter-task communication - Tasks can't message each other directly
