Below is the list of skills that can be used. Each entry includes a name, description, and file path so you can open the source for full instructions when using a specific skill.\n### Available skills\n- skill-creator: Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Codex's capabilities with specialized knowledge, workflows, or tool integrations. (file: /home/ubuntu/.codex/skills/.system/skill-creator/SKILL.md)\n- skill-installer: Install Codex skills into $CODEX_HOME/skills from a curated list or a GitHub repo path. Use when a user asks to list installable skills, install a curated skill, or install a skill from another repo (including private repos). (file: /home/ubuntu/.codex/skills/.system/skill-installer/SKILL.md)\n### How to use skills\n- Discovery: The list above is the skills available in this session (name + description + file path). Skill bodies live on disk at the listed paths.\n- Trigger rules: If the user names a skill (with `$SkillName` or plain text) OR the task clearly matches a skill's description shown above, you must use that skill for that turn. Multiple mentions mean use them all. Do not carry skills across turns unless re-mentioned.\n- Missing/blocked: If a named skill isn't in the list or the path can't be read, say so briefly and continue with the best fallback.\n- How to use a skill (progressive disclosure):\n  1) After deciding to use a skill, open its `SKILL.md`. Read only enough to follow the workflow.\n  2) If `SKILL.md` points to extra folders such as `references/`, load only the specific files needed for the request; don't bulk-load everything.\n  3) If `scripts/` exist, prefer running or patching them instead of retyping large code blocks.\n  4) If `assets/` or templates exist, reuse them instead of recreating from scratch.\n- Coordination and sequencing:\n  - If multiple skills apply, choose the minimal set that covers the request and state the order you'll use them.\n  - Announce which skill(s) you're using and why (one short line). If you skip an obvious skill, say why.\n- Context hygiene:\n  - Keep context small: summarize long sections instead of pasting them; only load extra files when needed.\n  - Avoid deep reference-chasing: prefer opening only files directly linked from `SKILL.md` unless you're blocked.\n  - When variants exist (frameworks, providers, domains), pick only the relevant reference file(s) and note that choice.\n- Safety and fallback: If a skill can't be applied cleanly (missing files, unclear instructions), state the issue, pick the next-best approach, and continue.\n</INSTRUCTIONS>",

      "text": "Here’s what’s going on and the fastest ways to fix it.\n\n**What Happened**\n- pip pulled the wandb source tarball (sdist) and tried to build its Go-based core, but no Go compiler is installed.\n- In this repo, wandb is optional and safely disabled by default: see `col/src/utils/wandb_utils.py:1` and `col/src/config/config.py:1`.\n\n**Quick Fix (prefer binary wheel)**\n- Upgrade packaging tools: `python -m pip install -U pip setuptools wheel`\n- Force a binary wheel (avoids building Go):\n  - Latest, if a wheel exists for your Python/OS: `pip install --only-binary=:all: wandb`\n  - If that still pulls sdist, pick a version with wheels for your Python (3.8–3.12 commonly have them):  \n    `pip index versions wandb`  \n    then install one with `pip install --only-binary=:all: wandb==<version>`\n\n**If You Don’t Need W&B**\n- Do nothing. W&B is optional and default-off; the code gracefully skips it if not installed and if `WANDB_ENABLED` isn’t set.\n\n**Other Options**\n- Conda (prebuilt): `conda install -c conda-forge wandb` (version may differ from PyPI; avoids Go build).\n- Install Go to build from source (only if you truly need the sdist):\n  - Conda: `conda install -c conda-forge go`\n  - Apt (requires sudo): `sudo apt-get update && sudo apt-get install -y golang-go`\n  - Then: `pip install wandb`\n\n**Why This Happens**\n- pip falls back to sdist when a compatible wheel isn’t available (or when pip is configured to avoid wheels).\n- If your pip config forces source builds, override with `--only-binary=:all:` or check via `pip config list` and remove any `no-binary=:all:` setting.\n\nWant me to help pick a specific wandb version for your Python/OS? Tell me your Python version (`python -V`) and platform (`uname -m && uname -s`).",
