frob 0.0.0

These are tools that I use in my development workflow.

frob

Developer workflow CLI tools. Designed for agentic and human use.

Install: pip install frob or uvx frob. For editable dev install: pip install -e .

Commands

frob init -- project scaffolding

frob init list                              # list registered project types
frob init new <type> <name> --output DIR   # scaffold a new project

Project types:

• python-library -- installable Python package with logging, tests, CI
• python-tool -- Python CLI tool with argparse, app/, config, CI
• cpp-library -- FetchContent-compatible C++ library with CMake, GTest/Catch2, CI
• cpp-tool -- C++ executable with CMake, cross-platform CI, release workflow
• pybind11-library -- hybrid Python/C++ library using pybind11 + scikit-build-core
• pyo3-library -- hybrid Python/Rust library using PyO3 + maturin

All templates include: Makefile, .gitignore, docs/, GitHub Actions CI, branch-protection workflow.

frob map -- project structure

frob map src/           # directory tree with token counts per file
frob map src/ --json    # JSON with path, lines, tokens, symbols per file
frob map src/ --depth 2 # limit recursion depth

---

frob outline -- file signatures

frob outline src/file.py           # functions and classes with line numbers
frob outline src/file.py --json    # structured JSON output

Shows signatures only -- no bodies. Fast way to see what is in a file before reading it.

---

frob stub -- single-function context

frob stub src/file.py target_fn              # keep target intact, stub everything else
frob stub src/file.py MyClass.method         # class method variant
frob stub src/file.py target_fn --output FILE

Useful for giving an LLM minimal context for one function.

---

frob bundle -- function + its dependencies

frob bundle src/file.py fn_name         # function + all functions it calls
frob bundle src/file.py fn_name --depth 2
frob bundle src/file.py fn_name --format json

---

frob tokens -- token count

frob tokens src/file.py            # total tokens
frob tokens src/file.py --detail   # per-symbol breakdown
frob tokens src/ --json            # JSON with total_tokens and per-file list

---

frob xref -- cross-references

frob xref symbol src/       # find definition + all callers of a symbol
frob xref symbol src/ --json

---

frob cycle -- import cycle detection

frob cycle src/             # detect import cycles
frob cycle src/ --suggest   # with refactoring suggestions

---

frob dup -- duplicate code detection

frob dup src/                       # find structurally identical code blocks
frob dup src/ --min-lines 10        # minimum block size
frob dup src/ --json                # JSON with groups, clone_type, fragments

Detects exact clones and renamed-variable clones.

---

frob arch -- architectural lint

frob arch src/                              # god-class, long-function, deep-nesting
frob arch src/ --json                       # JSON with suggestions list
frob arch src/ --max-function-lines 50
frob arch src/ --max-class-methods 20

---

frob docs -- docstrings and docs/ search

frob docs src/file.py                       # extract all docstrings
frob docs src/file.py MyClass               # docstrings for a specific symbol
frob docs src/file.py --overview            # relevant headings from docs/ folder
frob docs src/ --search "authentication"    # full-text search through docs/ .md files
frob docs src/file.py --json

---

frob bind -- binding consistency check

frob bind .                    # verify // BIND: comments match source declarations
frob bind . --json             # JSON with ok, mismatches list
frob bind . --list-bindings    # show all BIND declarations found
frob bind . --list-sources     # show all detected source signatures

Checks pybind11 (bindings.cpp) and PyO3 (lib.rs) // BIND: signature comments against actual C++ header declarations and Rust #[pyfunction] signatures.

---

frob parse -- parse tool output

<tool> | frob parse <tool>          # parse and summarize
<tool> | frob parse <tool> --json   # structured JSON
<tool> | frob parse <tool> --passthrough   # propagate exit code

Supported tools: pytest, ruff, ty, clang, junit, pycharm

---

frob inspect -- PyCharm headless inspection

frob inspect <project_dir>
frob inspect <project_dir> --json

---

Development

make install      # uv sync --all-extras
make format       # black + ruff format
make lint         # ruff + ty check
make test         # pytest tests/
make test-fast    # pytest --testmon (incremental)
make upload       # bump version if needed, build wheel, publish to PyPI
make clean

The .frob-foundation.md convention: when smart-start generates infrastructure code, it writes a registry of abstractions to .frob-foundation.md at the project root. The implementer agent reads this file automatically so it knows which base classes, protocols, and helpers already exist and should be used.
