+# OpenCode Setup
+
+[OpenCode](https://opencode.ai) natively loads [Agent Skills](https://agentskills.io) and reads
+`AGENTS.md`, so all six brooks-lint modes run with no conversion.
+
+## Install
+
+```bash
+# simplest — one command (global)
+curl -fsSL https://raw.githubusercontent.com/hyhmrright/brooks-lint/main/scripts/install.sh | bash -s -- opencode
+
+# from a clone
+./scripts/install.sh opencode            # global: ~/.config/opencode/skills
+./scripts/install.sh opencode --project  # this repo: ./.opencode/skills
+```
+
+Manual equivalent:
+
+```bash
+git clone https://github.com/hyhmrright/brooks-lint.git /tmp/brooks-lint
+mkdir -p ~/.config/opencode/skills
+cp -r /tmp/brooks-lint/skills/* ~/.config/opencode/skills/   # flat — brooks-* and _shared/ as siblings
+```
+
+OpenCode also discovers Claude-compatible `~/.claude/skills/*/SKILL.md`, so an existing Claude install
+(if flat) is picked up automatically.
+
+## Invoke
+
+Just ask — OpenCode auto-selects skills from each `description`:
+
+- "review this PR" → `brooks-review`
+- "audit the architecture" → `brooks-audit`
+- "where's our worst tech debt?" → `brooks-debt`
+
+For explicit invocation, `/brooks-review` etc. are available once the skill is discovered. The repo's
+`AGENTS.md` carries the Iron Law (Symptom → Source → Consequence → Remedy) and the Health Score rules.
+
+## Notes
+
+- **Flat layout** is mandatory (the installer guarantees it): skills read `../_shared/`, which only
+  resolves when `_shared/` sits beside the `brooks-*` folders.
+- 🧪 Documented per the official [skills](https://opencode.ai/docs/skills/) and
+  [rules](https://opencode.ai/docs/rules/) docs; community end-to-end verification welcome —
