OpenRig is a software harness that coordinates Claude Code and Codex coding agents as one system, with agent teams defined in YAML and launched together. It is for organizing persistent teams of coding agents that can delegate work to specialists and return results or decisions. The catalogue lists 53 skills and one plugin as add-ons for OpenRig.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

openrig-core scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it installs
The manifest is a name and a version. 19 skills travel with it, and installing the plugin installs all of them — 1,549 tokens a session between them. Each is measured on its own page, and each can be installed alone.

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

openrig-core is a plugin published in the GitHub repository mvschwarz/openrig (7,515 stars, last pushed today), licensed Apache-2.0. Its token cost is not measured: this kind of file is read by the harness, not the model. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other plugins, from other repositories
chrono-vault
Chrono squad memory: private off-repo markdown source of truth with disposable FTS5/BM25 recall, fail-closed root resolution, and per-lane sensitivity clearance.
rekal
Memory for your coding agent. Rekal saves every AI session transcript raw and append-only — no summaries to rot — then recalls the reasoning behind any change: why an approach was chosen, what was tried, what was rejected. Agent agnostic: Claude Code, Cursor, Codex, Gemini, Copilot, Kiro and OpenCode sessions all land.
symbiote
AI coding companion with persistent memory — code knowledge graph, developer DNA, and architectural intelligence via MCP.
aigon
aigon. Aigon is a local, open-source, spec-first software-delivery orchestrator for coding agents. It takes a Git-backed feature spec through isolated implementation, cross-agent review, and merge—using the agents and subscriptions you already have.
humanizer
Rewrite AI-sounding text so it reads like the writer without changing what it says.
nextjs
Official Next.js skills: adopt and optimize Cache Components, adopt Partial Prefetching, and verify runtime behavior against a running dev server.
