dekk 1.10.7

Reusable environment detection, activation, and wrapper tooling for developer CLIs.

dekk

Make project CLIs runnable with one config and zero manual activation.

Install

pipx install dekk

Fallback:

python -m pip install --upgrade dekk

Minimal Setup

dekk install ./tools/cli.py

If .dekk.toml is missing, dekk install and dekk wrap create a starter file from the repo context first.

Explicit template-driven setup is still available:

dekk init --example conda
eval "$(dekk activate --shell bash)"

Optional (no activation after this):

dekk wrap myapp ./tools/cli.py

Worktree-safe default:

dekk install ./tools/cli.py        # no shell rc PATH edits by default
dekk install ./tools/cli.py --update-shell

Project Command Routing

All project commands go through dekk <appname>, which finds the nearest .dekk.toml and runs with cwd set to that project root:

dekk myapp                   # project-aware help
dekk myapp --help
dekk myapp server --port 8080
dekk myapp build
dekk myapp test

This is worktree-friendly by default:

• dekk walks up from your current directory to find the nearest .dekk.toml
• the app name must match [project].name
• the command runs with cwd set to that project root, not whatever nested directory you happened to be in
• activation is scoped to that project config before the command runs

That means dekk myapp server works correctly from a repo root, a nested subpackage, or a separate Git worktree for the same project, without relying on global shell state.

Built-in Project Tools

Built-in tools (setup, agents, worktree) are project-scoped — they require the app name so dekk knows which project context to use:

dekk myapp setup
dekk myapp agents init
dekk myapp agents generate --target all
dekk myapp worktree create feature-x --base main
dekk myapp worktree list

Why the app name? Because dekk resolves paths from your current directory. The app name selects the project (validates against [project].name in .dekk.toml), and all paths resolve relative to that project root. This makes every command worktree-safe — it works correctly from any checkout.

Agents

Source of truth: .agents/

dekk myapp agents init
dekk myapp agents generate --target all
dekk myapp agents clean --target codex
dekk myapp agents install        # optional (installs Codex skills to ~/.codex/skills)

Generated files: AGENTS.md, CLAUDE.md, .cursorrules, .github/copilot-instructions.md, .agents.json

Worktrees

dekk myapp worktree create feature-x --base main
dekk myapp worktree list
dekk myapp worktree remove feature-x
dekk myapp worktree prune

Worktrees with .dekk.toml get automatic environment setup on creation. Auto-scaffolded as an agent skill via dekk myapp agents init for git repos.

Inheriting Tools in Downstream CLIs

CLIs built with dekk.Typer can also inherit these tools directly, useful when worktree isolation is not a concern:

from dekk import Typer

app = Typer(
    name="myapp",
    auto_activate=True,
    add_doctor_command=True,
    add_version_command=True,
    add_worktree_command=True,
    add_agents_command=True,
)
