lane is a Python package that inspects the current project state, reads recent git history, adds a user question for an LLM, and returns a concrete plan for the next 10 engineering tasks.

What is included

• Project snapshot analysis — README, manifests (pyproject.toml, package.json, Cargo.toml, …), directory tree, stack detection
• Git context — recent commits, most-changed files, TODO/FIXME markers
• Advanced code metrics — cyclomatic complexity, coupling analysis, bug hotspots, bus factor detection
• Koru-aware planning — Deep integration with koru framework for intelligent task generation
• Pydantic models — validated data models for tasks and plans (Task, TaskPlan)
• Provider abstraction — pluggable LLM backends; ships with an OpenAI-compatible provider (works with OpenRouter and any OpenAI-style API)
• Planner orchestrator — generate_next_tasks() composes analysis + prompt + LLM call into a validated TaskPlan
• Rich CLI — lane plan, lane auto, lane metrics, lane print-context, lane print-prompt, lane validate, lane tickets
• Reliability — httpx for HTTP, tenacity for automatic retry/backoff, pydantic-settings for environment config

Quick start

python -m venv .venv
. .venv/bin/activate
pip install -e .
lane print-prompt .

To generate a real plan, set OPENROUTER_API_KEY or OPENAI_API_KEY and run:

lane plan . --extra-context "What should we build next for this repository?"

Output as JSON:

lane plan . --json

Inspect captured project and git context without calling the LLM:

lane print-context .

Validate a saved plan file:

lane validate plan.json

Analyze code metrics and coupling:

lane metrics .

CLI Reference

lane plan

Generate a 10-task engineering plan for a repository.

Usage:

lane plan [REPO_PATH] [OPTIONS]

Options:

• --extra-context, -e TEXT: Additional prompt context for the LLM
• --model, -m TEXT: Override the LLM model name
• --base-url TEXT: Override the API base URL
• --json: Output plan as JSON instead of formatted text
• --max-commits INTEGER: How many recent commits to inspect (default: 30)

lane print-context

Print the assembled project and git context without calling the LLM.

Usage:

lane print-context [REPO_PATH] [OPTIONS]

Options:

• --max-commits INTEGER: How many recent commits to inspect (default: 30)
• --raw: Print raw text instead of Rich panels

lane print-prompt

Print the full prompt that would be sent to the LLM.

Usage:

lane print-prompt [REPO_PATH] [OPTIONS]

Options:

• --extra-context, -e TEXT: Additional prompt context for the LLM
• --max-commits INTEGER: How many recent commits to inspect (default: 30)

lane validate

Validate a saved JSON plan file against the TaskPlan schema.

Usage:

lane validate PLAN_FILE

lane auto

Auto-generate and sync tickets for the most important work. This is the quickest way to get actionable tickets into your planfile.

Usage:

lane auto [REPO_PATH] [OPTIONS]

What it does:

1. Analyzes project for high-priority issues (hotspots, complexity, coupling)
2. Generates tickets using koru-aware planning
3. Auto-syncs to .planfile/ for execution via koru queue

Options:

• --extra-context, -e TEXT: Additional prompt context for the LLM
• --dry-run: Show what would be done without executing

Example:

# Quick auto mode - analyze, generate, sync
lane auto

# With extra context
lane auto . -e "Focus on security improvements"

# Dry run to preview
lane auto --dry-run

Equivalent to:

lane tickets . --koru-aware --sync-planfile

lane metrics

Display comprehensive code metrics for the project including cyclomatic complexity, change coupling, bug hotspots, and bus factor analysis.

Usage:

lane metrics [REPO_PATH] [OPTIONS]

Options:

• --top, -n INTEGER: Show top N items per category (default: 10)
• --min-coupling FLOAT: Minimum coupling score to display (default: 0.3)

Metrics displayed:

• Cyclomatic Complexity per file (identify complex functions to refactor)
• Coupling Analysis — which files change together frequently (plan refactors together)
• Coupling Clusters — groups of tightly coupled files (sprint planning)
• Bug Hotspots — files with high bug fix rate and code churn
• Bus Factor — files with few authors (knowledge silos)

Example:

# Show metrics for current project
lane metrics .

# Show top 5 with higher coupling threshold
lane metrics . --top 5 --min-coupling 0.5

lane tickets

Generate tickets from a plan using planfile integration.

This command generates tickets from a TaskPlan and optionally syncs them to TODO.md, .planfile/, or exports to planfile YAML format.

Usage:

lane tickets [REPO_PATH] [OPTIONS]

Options:

• --extra-context, -e TEXT: Additional prompt context for the LLM
• --model, -m TEXT: Override the LLM model name
• --base-url TEXT: Override the API base URL
• --max-commits INTEGER: How many recent commits to inspect (default: 30)
• --sync-todo: Sync tasks to TODO.md checkboxes using planfile
• --sync-planfile: Store tickets in .planfile/ and sync with markdown
• --export-yaml: Export to planfile YAML format
• --output, -o PATH: Output file for YAML export
• --koru-aware: Enable koru integration schema for smart task planning

Examples:

# Generate and display tickets
lane tickets .

# Sync to TODO.md
lane tickets . --sync-todo

# Export to planfile YAML
lane tickets . --export-yaml --output strategy.yaml

# Koru-aware planning (generates tasks referencing koru operations)
lane tickets . --koru-aware --sync-planfile

Note: This feature requires the planfile package. It will be auto-installed if missing.

Configuration

Generate a plan for a Python project

lane plan /path/to/project --extra-context "Focus on improving test coverage"

lane plan . --model "openrouter/anthropic/claude-3.5-sonnet"

Inspect what data is sent to the LLM

lane print-prompt . --extra-context "Review security issues"
