Architect-level guidance, workflows, and scripts for building agentic coding systems with OpenAI Codex. Use for Codex SDK (@openai/codex-sdk) threads + streaming JSONL events; Codex CLI automation (codex exec, output schema, JSONL, resume); MCP server usage (codex mcp-server) and dynamic tool integration; multi-agent orchestration with OpenAI Agents SDK (handoffs, gating, tracing); durable state, caching, and memory using SQLite; safe-by-default sandbox/approval patterns and execpolicy rules.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Codex SDK + Codex CLI (master skill) Build reliable, auditable, multi-step coding workflows that scale from a single run to multi-agent orchestration. ## ExecPlans (durable planning) For multi-hour work, keep intent durable across compaction/restarts using an **ExecPlan**: - Contract: `references/execplans.md` - Template + rules: `.agent/PLANS.md` (use `scripts/init_agent_workspace.py` to bootstrap a repo) - ExecPlan skeleton: `assets/templates/execplan.md` (or generate a file with `scripts/new_execplan.py`) ## Workflow decision tree 1. **Need a scriptable one-shot in CI or cron?** → use `codex exec` (`references/codex-cli-exec.md`) 2. **Need a server-side app controlling Codex programmatically?** → use `@openai/codex-sdk` (`references/codex-sdk-typescript.md`) 3. **Need multi-agent orchestration or dynamic tools?** → run `codex mcp-server` and orchestrate via OpenAI Agents SDK (`references/mcp-and-agents-sdk.md`) 4. **Need durability across runs (memory, caching, resumable state)?** → persist run metadata and event logs in SQLite (`references/state-memory-sqlite.md`) ## Default workflow (safe + production-friendly) …

How to install
mdr add bjornmelin/dev-skills/codex-sdk@sha256:ffe61496b310acffThe line at the top of this page pins the label git:20260126.735ce96, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
