+# Codex Agents Marketplace
+
+## Overview
+
+136+ specialized agent definitions converted from [VoltAgent/awesome-codex-subagents](https://github.com/VoltAgent/awesome-codex-subagents) (OpenAI Codex format) to Claude Code plugin marketplace format.
+
+- **Repo**: `cal/codex-agents` on Gitea (`git@git.manticorum.com:cal/codex-agents.git`)
+- **Local path**: `/mnt/NV2/Development/codex-agents/`
+- **Upstream**: Cloned to `upstream/` (gitignored), pulled on each sync
+
+## Sync Pipeline
+
+```bash
+cd /mnt/NV2/Development/codex-agents
+./sync.sh              # pull upstream + convert changed agents
+./sync.sh --force      # re-convert all regardless of hash
+./sync.sh --dry-run    # preview only
+./sync.sh --verbose    # per-agent status
+```
+
+- `convert.py` handles TOML → Markdown+YAML frontmatter conversion
+- SHA-256 per-file hashes in `codex-manifest.json` skip unchanged agents
+- Deleted upstream agents are auto-removed locally
+- `.claude-plugin/marketplace.json` is regenerated on each sync
+
+## Format Mapping

+| `sandbox_mode: read-only` | `disallowedTools: Edit, Write` |
+| `sandbox_mode: workspace-write` | full tool access |
+| `developer_instructions` | markdown body |
+| `"parent agent"` | replaced with `"orchestrating agent"` |
