What it does
Claudex Second Opinion is an agent skill from ccplugins/awesome-claude-code-plugins. Suggests a cross-model second opinion after substantial or risky code changes. Use when a significant implementation, refactor, security-sensitive change, or uncertain bug fix has just been completed and is about to be committed or shipped. Advisory only — it recommends running /claudex:verdict; it never invokes Codex on its own.
Its SKILL.md is about 520 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Debugging and Refactoring. The repository describes itself as: Awesome Claude Code plugins — a curated list of slash commands, subagents, MCP servers, and hooks for Claude Code. The licence is Apache-2.0.
When your agent uses it
- A significant implementation
- Security-sensitive change
- Uncertain bug fix has just been completed and is about to be committed
Example prompts
- “Use the claudex-second-opinion skill to suggest a cross-model second opinion after substantial or risky code changes”
- “/claudex-second-opinion”
What it can do on your machine
Read from SKILL.md and the folder at commit 5bd4f16. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Claudex Second Opinion loads about 515 tokens when it runs. Until then it costs about 89 tokens; SKILL.md has 254 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Suggests a cross-model second opinion after substantial or risky code changes. Use when a significant implementation, refactor, security-sensitive change, or uncertain bug fix has just been completed and is about to be committed or shipped. Advisory only — it recommends running /claudex:verdict; it never invokes Codex on its own.
ClauDex Second Opinion
Overview
When a change is substantial or risky, suggest a cross-model review with
/claudex:verdict. Two frontier models trained by rival labs have different
blind spots — when both flag the same line it's the strongest free review
signal there is, and where they disagree is exactly where a human should look.
Hard rule: never run codex yourself under this skill. A cross-model
review spends the user's Codex quota and adds real latency. Explicit
invocation is consent — your job here is one well-timed suggestion, nothing more.
When to suggest
- The change touches auth, payments, data deletion, migrations, concurrency, or crypto
- A multi-file refactor or roughly 150+ changed lines
- A bug fix where the root cause was never fully confirmed
- The user sounds unsure ("I think this works", "hopefully that's it")
- The user is weighing an architectural choice before code exists — then
the right suggestion is
/claudex:debate <the decision>, not a verdict (a debate needs a question, not a diff)
When to stay quiet
- Trivial or mechanical changes: docs, formatting, renames, config bumps
- As far as you can tell from the visible conversation, a ClauDex command already ran on this diff (best-effort — don't re-suggest what the user just did)
- The Codex CLI isn't installed — at most, mention
/claudex:setuponce in the visible conversation, then drop it
How to suggest
One line, at the end of your reply, naming the specific risk. Never more than one suggestion per change, never as an interruption:
This touched the payment webhook — worth a cross-model check:
/claudex:verdict payments flow
