+# feat(opencode): compact AGENTS.md generator and JSON-only integration
+
+## What
+
+Add JSON-only OpenCode integration and a compact AGENTS.md generator (no large embeds; clickable file links) with idempotent merges for BMAD instructions, agents, and commands.
+
+## Why
+
+Keep OpenCode config schema‑compliant and small, avoid key collisions, and provide a readable agents/tasks index without inflating AGENTS.md.
+
+## How
+
+- Ensure `.bmad-core/core-config.yaml` in `instructions`
+- Merge only selected packages’ agents/commands into opencode.json file
+- Orchestrators `mode: primary`; all agents enable `write`, `edit`, `bash`
+- Descriptions from `whenToUse`/task `Purpose` with sanitization + fallbacks
+- Explicit warnings for non‑BMAD collisions; AGENTS.md uses a strict 3‑column table with links
+
+## Testing
+
+- Run: `npx bmad-method install -f -i opencode`
+- Verify: `opencode.json[c]` updated/created as expected, `AGENTS.md` OpenCode section is compact with links
+- Pre‑push checks:
+
+```bash
+npm run pre-release
+# or individually
+npm run validate
+npm run format:check
+npm run lint
+# if anything fails
+npm run fix
+# or
+npm run format
+npm run lint:fix
+```
+
+Fixes #<issue-number>

+Targets: `next` branch
