Feature parity with the Claude plugin suite has been implemented for the Codex plugin set under `core-agent/codex`.
## What Was Implemented
### Marketplace & Base Plugin
- Added Codex marketplace registry at `core-agent/codex/.codex-plugin/marketplace.json`.
- Updated base Codex plugin metadata to `0.1.1`.
- Embedded the Axioms of Life ethics modal and “no silly things with strings” guardrails in `core-agent/codex/AGENTS.md`.
### Ethics & Guardrails
- Added ethics kernel files under `core-agent/codex/ethics/kernel/`:
-`axioms.json`
-`terms.json`
-`claude.json`
-`claude-native.json`
- Added `core-agent/codex/ethics/MODAL.md` with the operational ethics modal.
- Added guardrails guidance in `core-agent/codex/guardrails/AGENTS.md`.
### Plugin Parity (Claude → Codex)
For each Claude plugin, a Codex counterpart now exists with commands, scripts, and hooks mirrored from the Claude example (excluding `.claude-plugin` metadata):
-`api`
-`ci`
-`code`
-`collect`
-`coolify`
-`core`
-`issue`
-`perf`
-`qa`
-`review`
-`verify`
Each Codex sub-plugin includes:
-`AGENTS.md` pointing to the ethics modal and guardrails
-`.codex-plugin/plugin.json` manifest
- Mirrored `commands/`, `scripts/`, and `hooks.json` where present
### Gemini Extension Alignment
- Codex ethics modal and guardrails embedded in Gemini MCP tools.
- Codex awareness tools return the modal content without shell execution.
## Known Runtime Constraints
- Gemini CLI currently logs unsupported hook event names (`PreToolUse`, `PostToolUse`). Hooks are mirrored for parity, but hook execution depends on runtime support.
- Shell-based command prompts are blocked by Gemini policy; MCP tools are used instead for Codex awareness.
-`claude/code/hooks.json` is not valid JSON in the upstream source; the Codex mirror preserves the same structure for strict parity. Recommend a follow-up fix if you want strict validation.
