Agent-Friendly CLI Builder

Turns Python CLI scripts into machine-readable NDJSON output behind a --json flag, or scaffolds a full cli_utils package.

Dev & CodingIntermediate★ 410⑂ 60AI score 8/10Last updated: Nov 5, 2026

What it does

  • Scans a Python script for output and exit points and replaces them with structured JSON events (NDJSON).
  • Generates a cli_utils.py with json_log, json_error, die, log, add_json_flag, enable_json, is_json, json_ready.
  • Optionally scaffolds a distributable package: src layout, pyproject.toml, pytest suite, MIT license, GitHub Actions CI.
  • Ships a done-checklist (flag visible in --help, every line parseable, interactive prompts and side effects guarded, no tracebacks leaking to stdout).

Who it's for

  • Python developers whose scripts are invoked by AI agents or automation pipelines.
  • Anyone exposing daemon/monitor status in a machine-readable stream.
  • Maintainers who want to publish a CLI helper library as open source.

Examples

  1. "Make hr_monitor.py agent-friendly" → prints become log()/die(), daemon startup emits {"event": "ready", "port": ...}.
  2. "Create a cli_utils package I can publish" → full package with tests and CI matrix for Python 3.10–3.13.
  3. "Verify my script's JSON output" → greps leftover raw prints, guards them, and walks the verification checklist.

Try it now, no install

Paste this into Claude to use the skill without installing anything.

Read the instructions in this file and follow them to help me:
https://raw.githubusercontent.com/glebis/claude-skills/HEAD/agent-cli/SKILL.md

What I want: (describe your task here)

If Claude can't open the link, open it yourself and paste the contents instead.

↓ If it works for you, download the ZIP below and install it. Then it runs on its own — no pasting each time.

Install in the Claude app (no terminal)
  1. Download the ZIP with the button below.
  2. In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
  3. Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.
↓ Download ZIP
Install in Claude Code

Let Claude do it — paste this into Claude Code

Install the skill I found on AI Skill Mart.
Copy the agent-cli folder from the GitHub repo glebis/claude-skills into my ~/.claude/skills/agent-cli/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/glebis/claude-skills.git /tmp/claude-skills && mkdir -p ~/.claude/skills && cp -r /tmp/claude-skills/agent-cli ~/.claude/skills/agent-cli

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal.
  2. Clone the repo: git clone https://github.com/glebis/claude-skills.git
  3. Create the skills directory: mkdir -p ~/.claude/skills
  4. Copy the skill: cp -r claude-skills/agent-cli ~/.claude/skills/agent-cli
  5. Confirm ~/.claude/skills/agent-cli/SKILL.md exists (and the references/ folder came along).
  6. Restart Claude Code and ask something like "add --json NDJSON output to this script" to trigger the skill.
