kage-ai 0.2.0

AI-native cron task runner for per-project scheduled prompts and commands.

kage 影 - Autonomous AI Project Agent

English | 日本語

kage is an ultra-lightweight, OS-native execution layer for AI agents. By leveraging standard schedulers like cron and launchd, it runs official AI CLIs (gemini, claude, codex, opencode, copilot, etc.) in headless mode with zero background overhead. You can install it on your work PC, define tasks in Markdown inside your project repository, and leave it running overnight. By morning, your AI agent has finished the work for you, delivering documented results while you were away.

Go to sleep. Wake up to results. — kage runs your AI agents overnight, so you start every morning with answers, not questions.

Design Philosophy

kage is built to be a thin, transparent, and resource-efficient execution layer.

• OS Native: Does not run a persistent background daemon. It leverages cron (Linux) and launchd (macOS) to wake up, execute tasks, and exit. Zero memory footprint when idle.
• Headless CLI Mode: Directly integrates with official AI CLIs (like gemini, claude, opencode, copilot, etc.) in their standard mode. It doesn't rely on unofficial or unstable internal APIs.
• Stateless & Transparent: Every execution is logged, and states are managed simply via SQLite and Markdown files.

Features

• Autonomous Agent Logic: Automatically decomposes tasks into GFM checklists and tracks progress.
• Persistent Memory: Stores task state in .kage/memory/ to maintain context across runs.
• Lightweight Execution: Leverages OS-native schedulers. Zero background overhead.
• Flexible Execution: Supports AI prompt execution, shell commands, and custom scripts.
• Advanced Workflow Controls:
  • Execution Modes: continuous, once, autostop.
  • Concurrency Policy: allow, forbid (skip if running), replace (kill old).
  • Time Windows: Restrict execution using allowed_hours: "9-17" or denied_hours: "12".
• Markdown-First: Define tasks using simple Markdown files with YAML front matter.
• Layered Configuration: .kage/config.local.toml > .kage/config.toml > ~/.kage/config.toml > defaults.
• Connectors: Bi-directional integration with external services like Discord and Slack.
• Web Dashboard: Execution history, task management, and AI chat — all in one place.

Installation

curl -sSL https://raw.githubusercontent.com/igtm/kage/main/install.sh | bash

Quick Start

cd your-project
kage init         # Initialize kage in the current directory
# Edit .kage/tasks/*.md to define your tasks
kage ui           # Open the web dashboard

Use Cases

🌙 Overnight Tech Evaluation (OCR Model Benchmark)

The killer use case: go to sleep, wake up with a complete technology evaluation report.

Create a single task that, on every cron run, picks the next untested OCR model, implements it, runs it against your test PDFs, and records the accuracy. By morning, you have a ranked comparison.

.kage/tasks/ocr_benchmark.md:

---
name: OCR Model Benchmark
cron: "0 * * * *"
provider: claude
mode: autostop
denied_hours: "9-23"
---

# Task: PDF OCR Technology Evaluation

You are conducting a systematic evaluation of free/open-source OCR solutions for extracting text from Japanese financial PDF documents.

## Target Models (test one per run)
- Tesseract (jpn + jpn_vert)
- EasyOCR
- PaddleOCR
- Surya OCR
- DocTR (doctr)
- manga-ocr (for vertical text)
- Google Vision API (free tier)

## Instructions
1. Check `.kage/memory/` for which models have already been tested.
2. Pick the NEXT untested model from the list above.
3. Install it and write a test script in `benchmark/test_{model_name}.py`.
4. Run it against the PDF files in `benchmark/test_pdfs/`.
5. Measure: Character accuracy (CER), processing time, memory usage.
6. Save results to `benchmark/results/{model_name}.json`.
7. Update `benchmark/RANKING.md` with a comparison table of all tested models so far.
8. When all models are tested, set status to "Completed" in memory.

When you wake up:

benchmark/
├── RANKING.md              ← Full comparison table, ready for decision
├── results/
│   ├── tesseract.json
│   ├── easyocr.json
│   ├── paddleocr.json
│   └── ...
└── test_pdfs/
    ├── invoice_001.pdf
    └── report_002.pdf

🔍 Overnight Codebase Audit

.kage/tasks/audit.md:

---
name: Architecture Auditor
cron: "0 2 * * *"
provider: gemini
mode: continuous
denied_hours: "9-18"
---

# Task: Nightly Architecture Health Check
Analyze the codebase for:
- Dead code and unused exports
- Circular dependencies
- API endpoints without tests
- Security anti-patterns (hardcoded secrets, SQL injection risks)

Write findings to `reports/audit_{date}.md`.

🧪 Overnight PoC Builder

.kage/tasks/poc_builder.md:

---
name: PoC Builder
cron: "30 0 * * *"
provider: claude
mode: autostop
denied_hours: "8-23"
---

# Task: Build a Proof of Concept

Read the spec in `specs/next_poc.md` and implement a working prototype.
- Create the implementation in `poc/` directory
- Include a README with setup instructions and demo commands
- Write basic tests to verify core functionality
- Set status to "Completed" when the PoC is functional

⚡ Simple Examples

AI Task — hourly health check:

---
name: Project Auditor
cron: "0 * * * *"
provider: gemini
---
Analyze the current codebase for architectural drifts.

Shell-Command Task — nightly log cleanup:

---
name: Log Cleanup
cron: "0 0 * * *"
command: "rm -rf ./logs/*.log"
shell: "bash"
---
Cleanup old logs every midnight.

Commands

Command	Description
kage onboard	Global setup (cron, directories, DB)
kage init	Initialize kage in the current directory
kage run	Execute current directory tasks once
kage cron install	Register to system scheduler
kage cron status	Check background status

macOS launchd Specific Settings

On macOS, kage uses launchd instead of cron. You can further customize its behavior in config.toml:

• darwin_launchd_interval_seconds: Set the launch interval in seconds (minimum 15).
• darwin_launchd_keep_alive: Set to true to keep the process running (not recommended for simple polling). | kage task list | List all tasks with status and schedule | | kage task show <name> | Show detailed task configuration | | kage connector list | List all configured connectors | | kage connector setup <type> | Show setup guide for a connector (discord, slack) | | kage connector poll | Manually poll all active connectors | | kage doctor | Diagnose configuration health | | kage skill | Display agent skill guidelines | | kage ui | Open the web dashboard |

Configuration

File	Scope
~/.kage/config.toml	Global settings
.kage/config.toml	Project-shared settings
.kage/config.local.toml	Local overrides (git-ignored)
