Install Experience Skills

Install Experience Skills into this coding-agent environment using the official repository instructions.

Official repository: https://github.com/moh-obaida/experience-skills
Installation documentation: https://github.com/moh-obaida/experience-skills/blob/main/docs/installation.md

First, inspect the official installation documentation and determine the correct installation method for this environment. Do not guess an install path that the documentation does not describe.

Documented methods:

1. Recommended: the skills CLI (verified upstream with skills CLI 1.7.0).
   - Interactive, choose skills and agents: npx skills add moh-obaida/experience-skills
   - List the collection without installing: npx skills add moh-obaida/experience-skills --list
   - One skill: npx skills add moh-obaida/experience-skills --skill experience-architect
   - User-level instead of this project: add -g
   - Non-interactive example for one agent: npx skills add moh-obaida/experience-skills --skill experience-architect -a claude-code -y
   - Copy files instead of symlinking: add --copy
   - Every skill and every agent the CLI supports, with no prompts: npx skills add moh-obaida/experience-skills --all
   - If this environment uses one agent, prefer --skill '*' -a <agent> rather than --all. In the documentation, --all means all skills and all agents.
   - Project installs go into the agent's project skills folder. For Claude Code that folder is .claude/skills/. The -g flag installs into the user folder.
   - Repository integration notes also name Codex, Claude Code, and Cursor as install locations, each using that agent's documented skills path. If the CLI's agent name for this environment is not clear from the documentation, stop and say so.

2. Manual: copy the needed skills/<name>/ folder from the repository into this agent's skills directory. Each folder is self-contained.

The recommended starting skill, when the problem is unclear, is experience-architect. Specialists also work on their own. use-all-skills is for a substantial product build or an explicit request to consider every skill; it should activate only specialists with material value.

Then:
- Install the current supported release. This prompt was prepared against collection version 0.7.1; confirm the version in the repository rather than assuming it is still current.
- Preserve my existing configuration and project files.
- Do not perform unrelated cleanup or refactoring.
- Do not overwrite unrelated skills or settings.
- Verify with the documented checks: run npx skills add moh-obaida/experience-skills --list and confirm the chosen skill folders are present in the agent's skills directory. Do not invent an extra verification command.
- Tell me exactly what you changed and where.
- Tell me which Experience Skills are now available and how I should invoke them. Most agents select skills from their descriptions. A direct ask the documentation gives is: "Use experience-architect to review the join page."
- Do not commit anything unless I explicitly ask.

Measurement scripts are optional. They need Node.js 18 or newer. Browser-based scripts need Playwright in the project being checked. Without those, the skills still work: the agent should use static analysis and say what it could not verify. Developing the Experience Skills repository itself is a separate task and asks for Node.js >= 20.11.

If anything required for installation is ambiguous or unsupported in this environment, stop and explain the issue rather than guessing.
