ain-pipeline 0.1.0

A.I.N. Pipeline — multi-agent AI development orchestrator

A.I.N. Pipeline

A local multi-agent orchestrator for structured, reproducible AI-assisted development.

Coordinates Gemini, Codex, ChiefLoop, and Claude through deterministic stages — producing planning artifacts before touching any code, and requiring human approval before implementation begins.

---

Installation

pip install ain-pipeline

This installs the ain CLI globally. You can then initialize the pipeline in any repository.

---

How it works

ain run

The pipeline executes these stages in sequence:

Repo Scan
  └─ Gemini → docs/architecture.md
       └─ Codex → OPEN_QUESTIONS.md
            └─ [you answer in OPEN_ANSWERS.md]
                 └─ Codex → PRD.md, DESIGN.md, FEATURE_SPEC.md
                      └─ ChiefLoop (or Claude) → TASKS.md, TASK_GRAPH.json
                           └─ [you approve]
                                └─ Claude → implements tasks
                                     └─ Validation → tests/lint
                                          └─ Done

Human involvement occurs at two points only:

1. Answering planning questions
2. Approving the task graph before implementation

---

Requirements

• Python 3.10+
• Git
• AI agent CLIs configured in .ai-pipeline/config.json:
  • gemini — architecture stage
  • codex — planning stage
  • chiefloop or claude --print — task creation stage
  • claude — implementation stage

---

Quickstart

# 1. Install
pip install ain-pipeline

# 2. Initialize the pipeline in your repo
cd your-project
ain init

# 3. Configure your agents
#    Edit .ai-pipeline/config.json

# 4. Run
ain run

# 5. The pipeline pauses after planning questions — answer them:
#    Edit docs/OPEN_ANSWERS.md, then continue:
ain run

# 6. Review the plan, then approve:
ain --approve

# 7. Pipeline runs implementation and validation automatically

---

Configuration

ain init writes .ai-pipeline/config.json to your repo. Edit it to configure agent commands, git behaviour, and validation.

Agent commands

{
  "agents": {
    "architecture": {
      "command": "gemini",
      "args": [],
      "model": null
    },
    "planning": {
      "command": "codex",
      "args": [],
      "model": null
    },
    "task_creation": {
      "command": "chiefloop",
      "args": [],
      "model": null
    },
    "implementation": {
      "command": "claude",
      "args": ["--allowedTools", "Edit,Write,Bash,Read,Glob,Grep"],
      "model": null
    }
  }
}

Set "model" to override an agent's default model. Each agent is invoked with the prompt piped via stdin and reads output from stdout.

ChiefLoop (task creation agent)

ChiefLoop is the task orchestration engine responsible for converting planning documents into a structured, dependency-ordered task graph (TASKS.md + TASK_GRAPH.json).

The pipeline defaults task_creation to claude --print so it works out of the box without ChiefLoop installed. To use ChiefLoop when available:

{
  "agents": {
    "task_creation": {
      "command": "chiefloop",
      "args": [],
      "model": null
    }
  }
}

Any agent used in this slot must:

1. Accept a prompt on stdin
2. Return output containing <!-- FILE: TASKS.md --> and <!-- FILE: TASK_GRAPH.json --> markers
3. Exit 0 on success

Git settings

{
  "git": {
    "auto_branch": true,
    "auto_commit": false,
    "branch_prefix": "ai/feature"
  }
}

auto_branch creates an ai/feature-<timestamp> branch before implementation begins. auto_commit is disabled by default — enable to commit automatically after validation passes.

Custom validation commands

The pipeline auto-detects validation commands from your project type (Laravel, Node, Python, Go, Rust). Override with explicit commands:

{
  "validation": {
    "auto_detect": false,
    "commands": [
      ["npm", "run", "lint"],
      ["npm", "test"],
      ["npm", "run", "build"]
    ]
  }
}

File structure

After ain init, your repo will contain:

your-repo/
├── docs/
│   ├── architecture.md                Generated by Gemini

The prompt files are yours to edit — they control exactly what each agent is asked to do.

Design principles

Agents communicate only through files. Gemini never talks to Codex. Codex never talks to Claude. Each agent reads documents and writes documents. This keeps the pipeline deterministic and auditable.

Planning is locked before implementation starts. The approval gate prevents Claude from implementing a plan that hasn't been reviewed. The flag file at .ai-pipeline/approvals/planning_approved.flag controls this.

Every decision is traceable. The scan artifacts, planning documents, task graph, implementation log, and validation log are all written to disk and can be committed to version control.

The pipeline is resumable. Any stage can be re-run with ain run --resume <stage>. If an agent produces bad output, fix the artifact manually and resume from the next stage.

---

Drop-in usage (no install)

If you don't want a global install, clone this repo and copy pipeline.py into your project. It works identically to the ain CLI as long as the ain/ package directory is alongside it:

# Clone or download pipeline.py + ain/ into your project
python pipeline.py init
python pipeline.py run
python pipeline.py --status

---

Warp Terminal

Workflow shortcuts are included in .warp/workflows/. Copy them to make them available globally in Warp:

cp .warp/workflows/*.yaml ~/.warp/workflows/

Available shortcuts: Pipeline — Run, Pipeline — Scan, Pipeline — Plan, Pipeline — Implement, Pipeline — Approve, Pipeline — Status, Pipeline — Reset.

---

Publishing (maintainer notes)

pip install build twine
python -m build
twine upload dist/*

Future releases:

# bump version in pyproject.toml, then:
python -m build && twine upload dist/*

---

Troubleshooting

Pipeline is stuck in failed state

ain --status                       # see the failure reason
ain run --resume <stage>           # resume after fixing the issue
ain --reset                        # or reset entirely

Agent command not found Edit .ai-pipeline/config.json and set the correct command for the failing agent. Verify the CLI is on your PATH.

Architecture validation failed The architecture document is missing required headings. Open docs/architecture.md, add the missing sections, then:

ain run --resume planning_questions

Planning documents are malformed The planning agent didn't use the required <!-- FILE: name.md --> markers. Check .ai-pipeline/logs/planning_last_output.txt for the raw output, fix the docs manually, then:

ain run --resume task_creation

Validation fails after implementation Check .ai-pipeline/logs/validation.log. Fix the issues in the codebase, then:

ain run --resume validation
