+# @paperclipai/plugin-missions
+
+First-party Missions plugin package for Paperclip mission orchestration workflows.
+
+This package is the packaging and installation home for the Missions plugin in the
+current alpha plugin runtime. Install is instance-wide, but the workflow it owns
+is company-scoped once the worker logic is invoked against company issues.
+
+Today this package carries the plugin identity, local install path, verification
+commands, and basic health surface. Mission advance/findings/waiver behavior
+continues to land in the same package under the sibling implementation issues.
+
+## Operator Workflow
+
+Build the plugin, then install it into the local Paperclip instance by repo path:
+
+```bash
+pnpm --filter @paperclipai/plugin-missions typecheck
+pnpm --filter @paperclipai/plugin-missions test
+pnpm --filter @paperclipai/plugin-missions build
+pnpm paperclipai plugin install ./packages/plugins/plugin-missions
+```
+
+The current first-party install path is a checked-out local package path. Do not
+document npm publishing for this plugin until the release/distribution path is
+ready.
+
+API install is equivalent:
+
+```bash
+curl -X POST http://127.0.0.1:3100/api/plugins/install \
+  -H "Content-Type: application/json" \
+  -d '{"packageName":"/absolute/path/to/paperclip/packages/plugins/plugin-missions","isLocalPath":true}'
+```
+
+Build first. The host loads the worker and UI from the manifest entrypoints under
+`dist/`, so a fresh install without a build will fail activation.
+
+## Developer Workflow
+
+From the repo root:
+
+```bash
+pnpm --filter @paperclipai/plugin-missions typecheck
+pnpm --filter @paperclipai/plugin-missions test
+pnpm --filter @paperclipai/plugin-missions build
+```
+
+For local iteration inside the package directory:
+
+```bash
+pnpm install
+pnpm dev
+pnpm dev:ui
+```
+
+## Maintenance Path
+
+The main package files are:
+
+- `src/manifest.ts` for plugin identity, capabilities, and mounted UI slots
+- `src/worker.ts` for worker lifecycle, state, events, and orchestration logic
+- `src/ui/index.tsx` for the currently mounted UI surface
+- `tests/plugin.spec.ts` for package-local verification
+
+When the Missions workflow changes, keep the package README and the targeted
+verification commands in sync with the actual install path and runtime surface.
+
+## Build Options
+
+- `pnpm build` uses esbuild presets from `@paperclipai/plugin-sdk/bundlers`.
+- `pnpm build:rollup` uses rollup presets from the same SDK.
