LazyCodex Install Doctor

Audits your LazyCodex and Codex CLI installation against the latest upstream sources and returns an evidence-backed PASS/WARN/FAIL report.

UtilitiesIntermediate★ 67,531⑂ 5,507AI score 6/10Last updated: Aug 9, 2026

What it does

A diagnose-only health check for a local LazyCodex (omo-codex) and Codex CLI installation.

  • Syncs the latest lazycodex and openai/codex sources into a temp source root and compares against real code instead of memory.
  • Inventories codex --version, command -v codex, bin links, CODEX_HOME/config.toml, the plugin manifest (.codex-plugin/plugin.json), and declared runtime payload files.
  • Distinguishes expected install-time path rewrites (e.g. absolute .mcp.json runtimes) from genuine drift.
  • Searches GitHub issues for each FAIL so known problems are linked rather than re-diagnosed.
  • Emits a table-based PASS/WARN/FAIL report plus prioritized remediations.

Core rule: nothing is mutated during diagnosis. Writes are limited to the source cache directory, and fixes are applied only if you ask afterward.

Who it's for

  • Developers actively using LazyCodex / omo-codex / Codex CLI.
  • Anyone whose Codex setup started misbehaving after an install, update, or config change.
  • Users suspecting a stale install, broken bin links, or missing plugin payload files.

Examples

  1. "Run a LazyCodex doctor check" → you get environment details, a six-row check table with evidence, and next actions.
  2. Hooks stopped firing after an update → the skill validates every manifest-declared hook path and points at the missing or zero-byte file.
  3. "Is my install drifted from latest?" → it compares installed vs. latest versions and reports only real drift, citing both local and upstream paths.

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the packages/omo-codex/plugin/components/lcx/skills/lcx-doctor folder from the GitHub repo code-yeongyu/oh-my-openagent into my ~/.claude/skills/lcx-doctor/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone --depth=1 https://github.com/code-yeongyu/oh-my-openagent.git /tmp/omo && mkdir -p ~/.claude/skills && cp -r /tmp/omo/packages/omo-codex/plugin/components/lcx/skills/lcx-doctor ~/.claude/skills/

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

  1. Open a terminal.
  2. Clone the repository shallowly: git clone --depth=1 https://github.com/code-yeongyu/oh-my-openagent.git /tmp/omo
  3. Create the skills folder: mkdir -p ~/.claude/skills
  4. Copy the skill in: cp -r /tmp/omo/packages/omo-codex/plugin/components/lcx/skills/lcx-doctor ~/.claude/skills/
  5. (Recommended) Make sure git and the GitHub CLI (gh) are installed and you've run gh auth login, since the skill clones upstream sources and searches issues.
  6. Restart Claude Code, then ask something like "run a health check on my LazyCodex install" to trigger the skill.
