Interpretation is structured for decision-making; original keeps the upstream SKILL.md unchanged.

Decide Fit First

Core job: Use at session start and before running shell commands involving Python, Node.js, file search, or HTTP requests. Use when this c…
Best fit: Use it when the task has reusable inputs, steps, and validation criteria rather than a one-off answer.
Avoid forcing it: If the source lacks commands, platform support, or external-service evidence, keep those fields unknown instead of guessing.

Design Intent

Structure: The skill is organized around “NEVER USE These Commands”, “Modern Replacements”, “Tool Not Installed?”, “Red Flags — You Are About to Violate This Skill”, showing how the author expects the agent to judge fit, collect context, and produce verifiable output.
Trigger evidence: Prioritize the author’s wording around when to use it, what context to collect, and what output shape to produce.
Evidence boundary: Author text states facts, repository files prove commands and paths, and Fluxly only adds fit, limits, and usage judgment.

How To Use It

Inputs: Provide target material, scope, expected result, forbidden changes, and validation method.
Invocation: Name modern-cli-tools directly; if the source includes slash commands, start with the command and then add task context.
Validation: Start small and check whether the result follows “NEVER USE These Commands / Modern Replacements / Tool Not Installed?” before expanding.

Boundaries And Review

Dependencies: It usually needs no extra API key, so start with a small validation task.
Permissions: Declared permissions include read / shell-exec; ask the agent to state file, command, and rollback boundaries before acting.
Quality bar: A useful result names the deliverable, evidence, and next action. Generic prose means the task needs tighter context.

NEVER USE These Commands

These commands are prohibited. No exceptions, no fallback.

Python:

pip, pip3, pip install, pip freeze
python -m venv, virtualenv
python, python3 (to run scripts — use uv run instead)

Node.js:

npm, npm install, npm run, npx
yarn

Node Versions:

nvm

Shell:

grep — use rg (ripgrep)
find — use fd

HTTP:

curl, wget — use xh

Modern Replacements

Task	Command	Replaces
Install Python package	`uv add <pkg>`	pip install
Run Python tool (one-off)	`uvx <tool>`	pipx run / pip install + run
Run Python script	`uv run script.py`	python script.py
Run Python tests	`uv run pytest`	python -m pytest
Sync Python environment	`uv sync`	pip install -r requirements.txt
Manage Python version	`uv python install 3.12`	pyenv / system python
Install Node packages	`pnpm install`	npm install / yarn
Run Node script	`pnpm run <script>`	npm run / yarn
Install Node version	`fnm install <version>`	nvm install
Use Node version	`fnm use <version>`	nvm use
Search file contents	`rg <pattern>`	grep -r
Find files	`fd <pattern>`	find . -name
Make HTTP request	`xh GET <url>`	curl / wget

Tool Not Installed?

Do NOT fall back to the legacy tool. Stop and tell the user to install the modern tool:

Tool	Official Site
uv / uvx	https://github.com/astral-sh/uv
pnpm	https://pnpm.io
fnm	https://github.com/Schniz/fnm
ripgrep (`rg`)	https://github.com/BurntSushi/ripgrep
fd	https://github.com/sharkdp/fd
xh	https://github.com/ducaale/xh

Example message to user:

"rg (ripgrep) is not installed. Install it from https://github.com/BurntSushi/ripgrep before continuing."

Red Flags — You Are About to Violate This Skill

Thought	Reality
"The tool isn't installed"	Tell the user to install it. Do NOT fall back to legacy tool.
"Just this once"	No exceptions. Use the modern tool or stop.
"This is a CI/container environment"	Still applies. Notify the user if the tool is unavailable.
"The existing script already uses pip/npm"	Tell the user to migrate. Do not propagate legacy tool usage.
"It's faster/easier to use grep here"	Use `rg`. It is faster.
"The user didn't ask me to use modern tools"	This skill is always active. It applies regardless.

## NEVER USE These Commands

These commands are **prohibited**. No exceptions, no fallback.

**Python:**

**Node Versions:**
- `nvm`

**Shell:**
- `grep` — use `rg` (ripgrep)
- `find` — use `fd`

**HTTP:**
- `curl`, `wget` — use `xh`
