pithy-cli 0.1.4

Your pithy python pair programmer CLI tool

Pithy

Your pithy python pair programmer

Dependencies

• uv
• Python version >=3.12
• pipx

Development Setup

# Install dev dependencies
uv sync --extra dev

# Install pre-commit hooks
uv run pre-commit install

# Run hooks manually on all files (optional)
uv run pre-commit run --all-files

Pre-commit Hooks

This project uses pre-commit hooks for code quality:

• File linting: trailing whitespace, end-of-file fixes, YAML/TOML validation
• Ruff: Python linting and formatting
• Mypy: Static type checking

Hooks run automatically on git commit. To skip hooks temporarily:

git commit --no-verify -m "your message"

Build steps

• uv build
• pipx install .

Features

Code Summarization

Generate structured markdown summaries of your source code files and directories using AI.

Quick Start

# Summarize a single file
pithy summarize path/to/file.py

# Summarize an entire directory
pithy summarize src/

# Summarize current directory
pithy summarize .

Output Structure

Summaries are written to timestamped subdirectories under .pithy/summarize/ at your git repository root. Each run creates a new timestamp directory in the format YYYY-MM-DD_HH-MM-SS:

.pithy/
└── summarize/
    ├── 2025-01-15_14-30-22/
    │   ├── src/
    │   │   ├── app.py.md
    │   │   ├── utils.py.md
    │   │   └── _meta.md
    │   └── README.md.md
    └── 2025-01-15_15-45-10/
        └── ...

• File summaries: .pithy/summarize/<timestamp>/<relative_path>.<ext>.md

  • Example: src/app.py → .pithy/summarize/2025-01-15_14-30-22/src/app.py.md
  • Contains AI-generated summary with key points, purpose, dependencies, and notes

• Directory meta: .pithy/summarize/<timestamp>/<relative_path>/_meta.md

  • Aggregates immediate files with one-line synopses
  • References subdirectories via links to their _meta.md files
  • Generated programmatically (no LLM calls)

Benefits of timestamped directories:

• Track evolution of your codebase over time
• Compare summaries from different points in development
• Never overwrite previous summaries
• Easy to identify when summaries were generated

Options

Option	Default	Description
path	.	File or directory to summarize
--exclude, -x	(none)	Glob patterns to exclude (repeatable)
--depth	-1	Maximum recursion depth (-1 = unlimited)
--force	False	Regenerate even if outputs are up-to-date
--dry-run	False	Show planned actions without writing files
--max-file-bytes	120000	Read limit per file (caps token usage)
--quiet	False	Reduce console output
--include-ignored	False	Process gitignored files

Default Exclusions

Gitignored files are automatically excluded by default. The summarize command respects your .gitignore file(s) and skips any files or directories that git would ignore. Use --include-ignored to override this behavior.

Additionally, the following patterns are always excluded:

• .git/, .pithy/
• node_modules/, dist/, build/, .venv/
• *.lock, *.min.*

Examples

Exclude specific files or patterns:

pithy summarize . --exclude "tests/*" --exclude "*.tmp"

Limit recursion depth:

pithy summarize src/ --depth 2

Force regeneration of all summaries:

pithy summarize . --force

Preview actions without writing:

pithy summarize src/ --dry-run

Quiet mode for scripting:

pithy summarize . --quiet

Include gitignored files:

pithy summarize . --include-ignored
# Processes everything, including files matched by .gitignore

Gitignore Integration

By default, pithy summarize respects your .gitignore files:

• Files and directories matched by .gitignore patterns are automatically skipped
• Nested .gitignore files are respected (follows git's hierarchy)
• Works seamlessly with your existing git workflow
• Use --include-ignored to process ignored files when needed (e.g., for documentation of build artifacts)

Example:

# .gitignore contains:
# build/
# *.pyc
# .env

# Default behavior - skips build/, *.pyc, .env
pithy summarize .

# Process everything, including gitignored files
pithy summarize . --include-ignored

Incremental Updates

By default, summaries are only regenerated when the source file is newer than the existing summary. This saves API calls and time on repeated runs. Use --force to override this behavior.

Cost Control

• Only file-level summaries invoke the LLM
• Directory _meta.md files are generated programmatically (deterministic, free)
• --max-file-bytes caps the amount of content sent per file (default: 120KB)
• Binary files are detected and skipped automatically

API Key Setup

Before using summarization, configure your LLM provider API key:

# For Anthropic Claude
pithy keys set anthropic

# For OpenAI GPT
pithy keys set openai

# Check provider status
