Hook rewrite: add coverage for uv run, pnpm exec, Python path variants, and more

Analyzed rtk discover output across 429 sessions (3,754 Bash commands) and identified ~727 missed commands that RTK already has subcommands for
but the hook script wasn't intercepting.

Updated rtk-rewrite.sh to cover all these patterns. Full test suite (55 cases) passing with zero regressions.

uv run dispatch — 378 commands (highest impact)

uv run ruff check/format ... → rtk ruff check/format ...
uv run pytest ... → rtk pytest ...
uv run python -m ruff check/format ... → rtk ruff check/format ...
uv run python -m pytest ... → rtk pytest ...
uv run mypy ... → rtk err uv run mypy ...

pnpm exec dispatch — 89 commands

pnpm exec vue-tsc --noEmit → rtk tsc --noEmit
pnpm exec eslint ... → rtk lint ...
pnpm exec prettier ... → rtk prettier ...
pnpm exec vitest [run] → rtk vitest run

pnpm script commands — 74 commands

pnpm type-check → rtk err pnpm type-check
pnpm build → rtk err pnpm build
pnpm add/install/remove → rtk pnpm add/install/remove

Python path variants — 150+ commands

Previously only pytest, .venv/bin/pytest, python -m pytest, and ruff check/format were handled. Now also covers:

api/.venv/bin/python -m ruff check ... → rtk ruff check ...
api/.venv/bin/python -m pytest ... → rtk pytest ...
python3 -m ruff check/format ... → rtk ruff check/format ...
.venv/bin/ruff check/format ... → rtk ruff check/format ...
api/.venv/bin/ruff check/format ... → rtk ruff check/format ...
mypy ... → rtk err ...
python -m mypy ... → rtk err ...
.venv/bin/python -m mypy ... → rtk err ...

uv sync — 10 commands

uv sync → rtk err uv sync

head -n fix (missing variant)

head -n 50 file → rtk read file --max-lines 50
head -n50 file → rtk read file --max-lines 50

Previously only head -50 file and head --lines=50 file were handled.

Testing

55 test cases (15 regression + 40 new), all passing:

• All new patterns with real-world command examples
• Edge cases: env var prefixes (PYTHONPATH=... uv run ruff), cd && cmd chains, heredoc skipping
• No regressions on existing patterns

Estimated impact

Based on rtk discover data (30-day window):

• ~727 additional commands would be intercepted
• Biggest wins: uv run (378), Python path variants (150+), pnpm exec (89), pnpm type-check/build (74)

Environment

• RTK version: 0.22.2
• Hook mechanism: Claude Code PreToolUse:Bash hook via settings.json

🤖 Hook analysis, implementation, and test suite generated with https://claude.ai/code.

Start with rtk-rewrite.sh and the existing 55-case hook test suite; compare the listed uv, pnpm, Python-path, uv sync, and head -n patterns with current rewrites. Done means the 40 new cases and 15 regression cases pass, including env prefixes, command chains, heredocs, and existing behavior.
