Problem

pyproject.toml has no [build-system] section. This means:

uv doesn't install the project itself into the venv — only dependencies
The CI pipeline uses uv pip install -e . (legacy pip-compat mode) to work around this
uv sync alone doesn't make import aco, import api, etc. work
Every time the venv is recreated, someone has to remember uv pip install -e .

There IS a [tool.uv.build-backend] section with namespace = true, but without [build-system] it doesn't activate.

Fix

Add to pyproject.toml:

[build-system]
requires = ["uv>=0.7,<1"]
build-backend = "uv"

uv's own build backend is the right choice here since [tool.uv.build-backend] is already configured.

Remove uv pip install -e . from:
- .woodpecker/ci.yml (line 18)
- Any mental model / workflow docs
After this, uv sync --dev will install the project editably AND all deps in one command.

Files

pyproject.toml
.woodpecker/ci.yml

## Problem `pyproject.toml` has no `[build-system]` section. This means: - uv doesn't install the project itself into the venv — only dependencies - The CI pipeline uses `uv pip install -e .` (legacy pip-compat mode) to work around this - `uv sync` alone doesn't make `import aco`, `import api`, etc. work - Every time the venv is recreated, someone has to remember `uv pip install -e .` There IS a `[tool.uv.build-backend]` section with `namespace = true`, but without `[build-system]` it doesn't activate. ## Fix 1. Add to `pyproject.toml`: ```toml [build-system] requires = ["uv>=0.7,<1"] build-backend = "uv" ``` uv's own build backend is the right choice here since `[tool.uv.build-backend]` is already configured. 2. Remove `uv pip install -e .` from: - `.woodpecker/ci.yml` (line 18) - Any mental model / workflow docs 3. After this, `uv sync --dev` will install the project editably AND all deps in one command. ## Files - `pyproject.toml` - `.woodpecker/ci.yml`
