—Claude Code · Codex · Gemini · Grok — a shared skill library across 4 CLIs

Design by Zephermine, build by Poseidon, audit by Argos.

Four CLIs share one workflow. From requirement interviews to parallel builds, closeout audits, and final docs — 100 skills turn one developer's process into a team's.

Harness and Loop Engineering

Act → Observe → Verify

Agents don't run on a single prompt — they run on loops: act, observe, verify. Skill Olympus was built that way from the start.

Foundation

Harness

Zeus is the foundation. One non-interactive request is kept alive, decomposed, implemented, inspected, deployed, tested, and reported — without handing "next steps" back to you.

Operating Model

Loop

Chronos is the operating model on top of it. A verification gate that runs real tests (Chronos), fix-until-pass (Minos), AC cross-check (Argos), GO/NO-GO (Clio) — since v4.7.0 these loops run on the native /goal stop gate.

Pantheon Roster

Pantheon Index — 06 / 12

01 ZeusPipelineALL-IN-ONE Runs 02–06 for you, in order — no questions asked, from a single one-line brief. /zeus 02 PoseidonBuild Splits the spec into dependency waves so an agent team can build them in parallel. /poseidon 03 MinosTest Loop Generates Playwright tests from the QA scenarios and loops until they pass. /minos 04 ArgosAudit Cross-checks the implementation against every design artifact at closeout. /argos 05 ChronosAutofix Works through issues one priority cycle at a time in an autonomous fix loop. /chronos 06 ClioClose A final GO/NO-GO review, plus a PRD, technical docs, and a manual — generated in one pass. /clio

One Pipeline

Interview → Build → Audit → Ship

01 — Design

Zephermine asks first

Stakeholder interviews and domain analysis become a section-by-section build plan. Questions come before code.

02 — Build

Poseidon puts a team to work

Section dependencies are grouped into waves; an agent team implements them in parallel.

03 — Audit

Argos cross-checks

Spec, API contracts, QA scenarios, flow diagrams — the implementation is checked against every design artifact.

04 — QA

Minos sits in judgment

Generates Playwright tests from the QA scenarios and loops until they pass.

05 — Close

Clio writes it down

A final GO/NO-GO review, plus a PRD, technical docs, and a manual — generated in one pass.

Four CLIs. One Team.

One run of install.bat installs the same skills on Claude Code, Codex, and Gemini. Grok Build needs no install at all — its Claude-compat layer reads ~/.claude directly.
