cli-tools-kit

A small library for self-installing Python CLI/GUI tools on Linux and Windows desktops. Provides:

• ToolInstaller — install/remove .desktop shortcuts or bash aliases for a Python script, including auto-sourcing ~/.tools_aliases from ~/.bashrc.

• CronInstaller — idempotent cron-line management with marker comments so each tool's entries can be installed/removed without disturbing others.

• advertise() — a one-line helper for the --advertise JSON probe convention that lets parent installers discover and configure your tools.

• skill_status() — detect whether a tool's installed Claude Code skill (~/.claude/skills/<name>/) is absent, current, or stale vs. its bundled version, so an installer can suggest updates (skill_payload_hash, installed_skill_hash, read_installed_skill alongside).

• gui_installer — a full, reusable tkinter GUI installer engine: it discovers every tool in a project tree that speaks --advertise, and offers batch install/remove, per-row skill toggles, themes, orphan cleanup, and an opt-in login update-check. A thin wrapper points it at its own tree via gui_installer.run(root_dir=..., entry_script=...); everything else (discovery layout, repo-cache bootstrap, login-check policy, window/desktop identities) is configurable. See § GUI installer engine.

• sources — one installer offering tools from several repos. A TOML file lists them, the kit clones what is missing over HTTPS and hands the engine one discovery root per repo. See § Sources.

See PROTOCOL.md for the full --advertise specification.

Install

pip install cli-tools-kit

Or pin in requirements.txt:

cli-tools-kit==0.6.0

The git URL form still works if you need an unreleased commit: pip install git+https://github.com/Probst1nator/cli-tools-kit.git@v0.6.0.

Requires Python ≥ 3.10. Optional runtime dep: termcolor (colored install/remove output; falls back to plain text if absent).

Minimal example

#!/usr/bin/env python3
import sys
from cli_tools_kit import ToolMetadata, ToolInstaller, advertise

# MUST come before any heavy imports!
if "--advertise" in sys.argv:
    advertise(ToolMetadata(
        name="My Tool",
        desktop_file="my_tool.desktop",
        icon="utilities-terminal",
        desc="Does the thing",
        tags=["CLI"],
        alias="mytool",
    ))

import argparse

def main() -> None:
    parser = argparse.ArgumentParser()
    parser.add_argument("--install", action="store_true")
    parser.add_argument("--remove", action="store_true")
    args = parser.parse_args()

    installer = ToolInstaller(
        script_path=__file__,
        metadata=ToolMetadata(
            name="My Tool",
            desktop_file="my_tool.desktop",
            icon="utilities-terminal",
            desc="Does the thing",
            tags=["CLI"],
            alias="mytool",
        ),
    )
    if args.install:
        installer.install()
    elif args.remove:
        installer.remove()

if __name__ == "__main__":
    main()

After python my_tool.py --install, the mytool alias is available in new shells (run source ~/.bashrc to pick it up immediately). On Windows the same call writes a mytool shim instead — see § Windows.

Windows

The kit runs on Windows as well as Linux. Every platform decision lives in cli_tools_kit/host.py; the differences a user sees are these.

• A CLI tool has no bash alias. --install writes two launcher scripts into %LOCALAPPDATA%\<slug>\bin: <alias>.cmd for cmd.exe and PowerShell, and an extensionless <alias> shell script for Git Bash, which is the shell Claude Code uses. That directory is added to the user's PATH once, so open a new terminal after the first install.
• A tool tagged Icon gets a Start Menu shortcut (.lnk) instead of a .desktop file, and autostart copies that shortcut into the Startup folder. Cron-scheduled autostart is not supported on Windows.
• The tkinter installer window works out of the box. The text screen (--tui) needs curses, which Python for Windows does not ship: pip install windows-curses.

Cron entries

from cli_tools_kit import CronInstaller

cron = CronInstaller("my-tool")   # unique marker for this tool's entries

cron.install([
    f"@reboot cd {SCRIPT_DIR} && python {SCRIPT} --daemon",
    f"0 6 * * * cd {SCRIPT_DIR} && python {SCRIPT} --daily",
])

# Later:
cron.remove()                     # strips only lines bearing this marker

Each managed line gets a trailing # cli-tool-kit:<marker> comment. The marker keeps the old project spelling so cron lines installed before the rename still match. Re-installing the same lines is a no-op; other tools' cron entries are untouched.

Reusing the installer in your org

cli_tools_kit.gui_installer is a batteries-included tkinter installer that any tool tree can reuse instead of forking. Point it at your tree and it discovers every tool that answers --advertise, then installs or removes each one's desktop entry, shell alias and Claude Code skill.

Start here:

cd /path/to/your/tools
python3 -m cli_tools_kit

That prints a brief you can paste into your coding agent (Claude Code or similar); the agent interviews you for the handful of naming decisions and writes the wrapper. --interactive answers the same questions on the command line instead, and --print-wrapper just prints the skeleton. A complete worked example — wrapper plus a tool — is in examples/org-installer/.

Identity: what your installer claims on a host

Several organisations' installers can share a machine, so yours needs a name of its own. InstallerIdentity derives every per-host artifact from one slug:

# my-org-tools/installer.py
import os
from cli_tools_kit import InstallerIdentity
from cli_tools_kit.gui_installer import run

HERE = os.path.dirname(os.path.abspath(__file__))

if __name__ == "__main__":
    run(
        identity=InstallerIdentity(slug="acme-tools", title="Acme Tools"),
        root_dir=HERE,
        entry_script=__file__,
    )

Derived from slug="acme-tools"	Value
config + icon overrides	~/.config/acme-tools/
shell aliases	~/.acme_tools_aliases
icon cache	~/.cache/acme-tools/
the manager's own shortcut	acme-tools-installer.desktop
WM class	acme_tools_installer
login-check artifacts	acme-tools-check.{desktop,log,json}
.desktop marker	Keywords=acme-tools;ai;tool;

That last one matters most: it is how the installer's orphan sweeper decides a shortcut is its shortcut. With distinct markers, two organisations' installers never delete each other's entries. Every derived name can be overridden with the matching InstallerIdentity field (config_dir, aliases_file, wm_class, …).

Passing no identity selects the historical first-party names, so existing installs are untouched by an upgrade. Running the engine bare — no identity, no wrapper — stops and offers setup rather than claiming those names.

run()

Keyword-only; every argument defaults to None, meaning "leave the default".

Argument	Default	What it does
identity	LEGACY_IDENTITY	The names above. The one argument a third party should always pass.
root_dir	cwd	The tree to manage. Discovery, .env loading and the self-shortcut's Path= all anchor here.
entry_script	this module	The script the manager shortcut and the login-check autostart entry launch. Pass __file__ so they re-enter your wrapper, not the bare engine.
discoverer	flat + tools_*/ walk, or the wider walk once discovery_roots is set	callable(root) -> [(entry_point_path, category), …]. Pass your own for a differently shaped tree.
prune	None	Extra directory names the default wider walk never enters, on top of the built-in set. Ignored when you pass your own discoverer.
discovery_roots	[root_dir]	Scan these directories instead — for tools that live in a subdirectory or several.
group_by	"capability"	Which field bands the GUI rows: "capability" (the advertised word) or "category" (whatever your discoverer assigned). Anything else raises ValueError.
pre_discovery	None	callable(refresh: bool) run once before scanning, for side effects like cloning repos into a cache. Skipped on the --check path so a login hook never touches the network.
check_reconcile_shortcuts	True	Whether --check also reinstalls drifted shortcuts. Set False when your tools' --install has side effects unsafe for a login hook, making --check skill-only.
skill_targets	[claude_target()]	Where the text screen can register a skill — see "The text screen" below.
tui_preselect	None	Initial ticks on the text screen: None ticks everything on a host with nothing installed yet and otherwise mirrors the host; True/False force one or the other.
window_title	identity's title	GUI window title.
self_desktop_file, self_desktop_name, self_desktop_icon	identity's	The manager's own shortcut.
wm_class	identity's	StartupWMClass for window-manager grouping.
notify_app	identity's	notify-send application label on the --check path.
autostart_check_desktop_name, check_log_name, check_state_name	identity's	Login-check artifact filenames.

The identity is applied first and these individual names override it, so you can take the whole namespace from a slug and still change one thing.

run() owns its own argparse and consumes sys.argv: --list, --check, --enable-autostart-check, --install, --update-all, --cleanup, --tui, --gui, and a screen when given none of them. A wrapper that needs its own subcommands should skip run() and call the primitives (discover_tools, install_tool, remove_tool, cli_check) after applying an identity with _apply_identity.

The text screen

Without a display (DISPLAY/WAYLAND_DISPLAY unset: SSH, WSL, a server) or without python3-tk, run() opens a curses screen instead of the tkinter window; --tui and --gui force either. Same rows, same Apply: Space ticks Install, s ticks Skill, a/n tick all or none, Enter applies, q quits. On a host where none of the tools is installed yet every row starts ticked.

A skill can go to more than one place. The default target writes ~/.claude/skills/<name>/ through the tool's --install-skill; a wrapper adds others with skill_targets, and the screen lets the user tick which ones Apply writes to (keys 1..9):

from cli_tools_kit.tui_installer import SkillTarget, claude_target

session = SkillTarget(
    key="fauclaude", label="fauclaude session plugin",
    installed=lambda tool: ...,          # bool
    install=lambda tool: (True, "..."),  # (ok, output)
    uninstall=lambda tool: (True, ""),
)
run(identity=IDENTITY, root_dir=HERE, entry_script=__file__,
    skill_targets=[claude_target(), session])

Without any screen, --apply NAMES installs the named tools (aliases, or all) and their skills, --skill-target KEYS says where the skills go (claude, a wrapper's own keys, or none). This is what a coding agent runs when it sets a machine up from a pasted prompt:

./installer.py --apply xrdlab,cifsearch --skill-target claude,fauclaude

The screen calls the engine's install_tool / remove_tool / skill functions by name at run time, so a wrapper that replaced them (to run each tool in its own venv, say) is honoured there too.

Discovering your tools

With one root_dir, the default discoverer accepts two layouts, and a tree may mix them:

• flat — <root>/<tool>/main.py (plus requirements.txt). Category empty, so rows band by each tool's advertised capability.
• nested — <root>/tools_<category>/<tool>/main.py, where the folder supplies the category label.

Directories starting with _ or . are skipped.

With discovery_roots — several repos, each shaped as its authors liked — the default is a wider walk of every root. A directory is a tool when it holds requirements.txt next to main.py or <dirname>.py with dashes written as underscores, which is how a one-tool repo names its script (manim-kit ships manim_kit.py). The root itself counts, so such a repo is one tool. The walk goes four levels deep at most and never enters .venv, venv, .git, node_modules, __pycache__, out, cache, build, dist, archive, a name starting with vendor, or a dot directory. Pass prune=[...] to add more names to that list. The category is the tool's parent directory name, empty when the parent is the root, and the root's own name when the tool is the root.

Anything else: pass a discoverer. If an expected tool does not appear, its --advertise is the thing to fix — it must print JSON and exit before any heavy import, or it trips the 5-second probe timeout. See PROTOCOL.md.

Grouping rows by meaning

group_by="capability" bands rows by the one word each tool advertises. Once a tree outgrows that, cli_tools_kit.taxonomy reads what the tree already documents about itself and produces a small set of named categories:

from cli_tools_kit.taxonomy import ensure_groups

def discover(root):
    groups = ensure_groups(root)          # {tool_name: band label}
    return [(entry, groups.get(name, "")) for entry, name in my_walk(root)]

It fingerprints every CLAUDE.md/README.md in the tree and rebuilds only when one changed (content hashes, not mtimes — a sync checkout restamps mtimes). Three tiers, tried in order so it degrades rather than failing: an LLM naming and filling the categories (Gemini via GEMINI_API_KEY, else a local LM Studio / Ollama server), else the advertised capability words banded into a fixed six, else embedding + k-means. Nothing configured means tier two, which is instant and needs no network.

The GUI extra

Icon thumbnails need Pillow:

pip install "cli-tools-kit[gui]==0.6.0"

Installing the package also exposes a cli-tool-installer console script.

Sources: installing tools from several repos

An organisation's tools rarely sit in one checkout. cli_tools_kit.sources reads a list of repos from a TOML file, puts each one on disk, and hands the engine one discovery root per repo. The installer that consumes it is a few lines long.

installer.toml is tracked and shared by everyone:

[[source]]
name = "acme/tools"
path = "."                                    # relative to this file

[[source]]
name = "acme/lab"
url = "https://github.com/acme/lab-tools"     # cloned into <root>/acme/lab

[[source]]
name = "manim-kit"
url = "https://github.com/AutomatedAlchemy/manim-kit"

installer.local.toml next to it is optional and belongs to one machine, so keep it out of git. It sets the root and replaces a path for a source matched by name:

root = "/home/me/checkouts"

[[source]]
name = "acme/lab"
path = "/home/me/work/lab-tools"

A source resolves in this order: the path from the local file, then the path from the tracked file, then an existing <root>/<name>, then a clone of url into <root>/<name>.

The root is --root DIR if given, else the local file's root, else the answer to a question. The GUI asks in a small dialog before discovery, the text screen asks in one line on stdin, and both suggest <current directory>/<name> as an absolute path — <name> is run_installer's default_root_name, tools by default. The answer is written into installer.local.toml as its root, above any [[source]] tables already there, so the question is asked once per machine; a root that file already has is left alone. The directory is created if it does not exist, and cancelling the dialog installs nothing.

A headless run never asks: --list, --apply, --check, or a text screen with no terminal take the suggestion and print root: /abs/path (pass --root to change).

Cloning is deliberately narrow. Only https:// URLs are cloned, ext:: and file:// transports and any hook are switched off for the git call, the clone is full rather than shallow (a tool that stamps its output with its commit needs the history), and nothing is cloned into a root that does not exist or cannot be written to. A clone that fails prints one line and that source is dropped, so a colleague without access to a private repo still gets everybody else's tools. --refresh brings the clones up to date with git pull --ff-only; a checkout given by path is never pulled. Cloning happens in the engine's pre_discovery hook, which --check skips, so the login check stays network-free.

A repo that is itself an installer tree can carry its own installer.toml. Its [[source]] entries are resolved too, one nested level deep and no further, with paths relative to that file and clones under the same root. A path that is already resolved is not visited twice, so a file pointing back at its parent cannot loop, and duplicates are dropped.

The consumer:

#!/usr/bin/env python3
import os
from cli_tools_kit import InstallerIdentity
from cli_tools_kit.sources import run_installer

HERE = os.path.dirname(os.path.abspath(__file__))
run_installer(os.path.join(HERE, "installer.toml"),
              identity=InstallerIdentity(slug="acme-tools", title="Acme Tools"),
              default_root_name="acme-tools",
              entry_script=__file__)

run_installer takes --root DIR for itself and leaves every other flag to the engine, so --list, --apply, --skill-target, --check, --refresh, --tui and --gui work as they do without sources. Every keyword besides config_path, argv and default_root_name goes to run(); discovery_roots and pre_discovery are the function's own to set and passing either raises TypeError.

Without a wrapper, the same thing from the command line:

python3 -m cli_tools_kit install path/to/installer.toml --list

That surface uses the default installer identity, so an organisation that wants its own namespace on the host writes the wrapper above and runs that.

The two loaders are usable on their own:

from cli_tools_kit.sources import load_sources, resolve_sources

sources = load_sources("installer.toml")            # [Source(name, url, path), …]
roots = resolve_sources(sources, root="~/acme-tools", refresh=False)

resolve_sources returns one Path per repo it could resolve and logs a line per repo it could not (log= takes any callable, print by default). Pass clone=False to resolve from the filesystem alone and never reach the network. Reading the TOML needs Python 3.11 or the tomli package, which is a dependency on 3.10.

Tests

pip install -e ".[dev]"
pytest

Used by

Consumers, each a self-installing tool that answers --advertise:

• studon-client — ToolInstaller + CronInstaller + a Claude Code skill
• BlogGen — install machinery falls back gracefully when the kit is absent
• lernclaude — same pattern
• manim-kit — reports skill_status

Two parent installers built on gui_installer are private (a tools_*/<tool>/main.py monorepo and a flat tree bootstrapped from a repos.json cache); a third walks a lab-tools tree and gives each tool its own venv.
