Pantheon X

Category: Security  ·  Sub-category: security-misc  ·  Last updated:
ai:openaiai:agent
A skill that runs a hard, testable coding task through a multi-agent harness (enhanced variant: GPT-5.5 cross-model adversarial verification). It takes implementations, large refactors, or migrations whose correctness can be expressed as tests and runs them through plan → parallel variants (test-driven self-correction loop) → **GPT-5.5 (Codex) adversarial verification** → synthesis. Because the implementation Claude wrote is attacked by a *different* model, it's stricter than the base (pantheon). Requires a Codex CLI login. Use when the user says "pantheon x", "pantheon enhanced", "GPT-5.5 adversarial verify", "cross-model hard verification", or wants the strongest cross-verified pipeline. If Codex/GPT-5.5 isn't available, use the pantheon skill instead. Don't use for easy one-shot work (cost is high).

From the source SKILL.md

Same plan → parallel variants → test-driven self-correction → adversarial verification → synthesis pipeline as the pantheon base, but the adversarial verification step is run by GPT-5.5 (Codex) (agentType: 'codex:codex-rescue'). Because a different model tries to break what Claude wrote, it shrinks single-model blind spots (the same mistake a same-model verifier would miss) — the strongest setting.

What this skill does

Pantheon X is a community-contributed Claude Code skill in the security-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/pantheon-x/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when the user says "pantheon x", "pantheon enhanced", "GPT-5.5 adversarial verify", "cross-model hard verification", or wants the strongest cross-verified pipeline.

Who uses this skill

The Pantheon X Claude Code skill is built for security engineers, penetration testers, DevSecOps practitioners, and development teams hardening codebases and infrastructure. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 117,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

Frequently asked questions

How do I install the Pantheon X Claude Code skill?
Install via the ClaudSkills desktop app (one click) or copy SKILL.md from the source repository to ~/.claude/skills/pantheon-x/SKILL.md and restart Claude Code. Both flows are detailed at claudskills.com/install/.
What does the Pantheon X skill do?

Is this skill free to install?
Yes. ClaudSkills is an open registry — every skill keeps its source repository's license, and manual install via copy is free. ClaudSkills Pro ($9/mo, $79/yr, or $149 one-time) adds one-click install via the desktop app and a multi-signal Quality Score.
When should I use the Pantheon X skill?
Use Pantheon X when your Claude Code task falls under the Security category — specifically in the security misc area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Pantheon X" or describe the task and let Claude pick). Browse related skills at /category/security/.
What is a Claude Code skill and how does the Pantheon X skill fit in?
A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Pantheon X is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Security category.
