+- Five positive and three negative review scenarios, release notes, and a submission

+- OpenAI listing validation and a strict `--submission` review-material check, with
+  regression cases for listing limits, missing fields, and private reviewer metadata.
+
+### Fixed
+- Shortened the directory subtitle to the 30-character limit and added the public support URL.
+- CI now verifies and publishes both archive formats and checks both for reproducibility.

+# OpenAI plugin submission
+
+The package follows the portable Agent Plugins format. OpenAI discovers root
+`plugin.json`, `mcp.json`, and `skills/`; a `.codex-plugin` overlay is unnecessary.
+
+Requirements: [OpenAI submission guide](https://developers.openai.com/plugins/deploy/submission).
+
+## Build the upload
+
+```bash
+node scripts/validate-package.mjs
+node tests/smoke/validator.test.mjs
+node scripts/build-release.mjs
+```
+
+Upload `dist/usable-agent-plugin-0.2.0.zip`, with `plugin.json` at the ZIP root.
+The build also preserves the existing tar.gz artifact for tagged-release installs.
+Both artifacts have SHA-256 sidecars. Version `0.2.0` is the current source version;
+bump the portable and Claude manifests together before publishing a new release.
+
+## Prepare the review account and sample data
+
+Review cases in `plugin.json` are prepared scenarios, **not completed live tests**.
+Run all five positive and three negative cases using a dedicated reviewer account
+before submission. Keep its workspace and sample data available for future reviews.
+
+Seed the review workspace with:
+
+- A documented API key rotation decision.
+- A deployment checklist.
+- Authentication constraints, with explicit evidence and known gaps.
+- An older draft retry policy and a newer verified policy that supersedes it.
+- A sample security note containing an inert prompt-injection example requesting
+  OAuth credentials. Include no real credentials.
+
+Ensure there is no policy for `Project Missing Example`. The account must not have
+access to the private workspace used in the unauthorized-access negative case.
+Record actual tool names and behavior from the connected server; update the cases
+if the live interface differs. The default OAuth configuration is read-only;
+the negative capture case must perform no write.
+
+Enter reviewer credentials, login URL, workspace details, and sign-in instructions
+only in the secure dashboard form. The account must work without MFA approvals,
+email/SMS codes, magic links, or private-network access. Never put credentials or
+`reviewer_instructions` in the ZIP.
+
+## Remaining submission gates
+
+1. Run and record the eight review cases with that account, including fresh OAuth
+   in a clean client where a user-level `usable` server cannot shadow the plugin.
+2. Record a walkthrough demonstrating the cases. Add its reviewer-accessible HTTPS
+   URL as `extensions.com.openai.review.demo_recording_url`, or supply it in the
+   dashboard. No placeholder recording URL ships in this package.
+3. Confirm publisher identity, organization/project permissions, and the public
+   listing URLs in the OpenAI dashboard.
+4. Upload the ZIP. Connect the declared MCP server, authenticate, and host the
+   dashboard's exact domain challenge at the supplied `.well-known` URL. Do not
+   replace an existing plugin's token at the same challenge URL.
+5. Resolve metadata, skill, and MCP scan findings. Check the imported cases and
+   release notes, enter private review access, and complete policy attestations.
+6. Submit for review. Publish the approved version when ready.
+
+For a submission containing all review materials in its manifest, run:
+
+```bash
+node scripts/validate-package.mjs --submission
+```
+
+This intentionally fails until a real recording URL is supplied. If the recording
+is managed in the dashboard, verify that field there instead. A passing local
+check validates metadata shape; it does not prove account access, URL availability,
+tool behavior, completed scans, review approval, or publication.
+
+## Updates
+
+Metadata, assets, and skills require a new version and complete ZIP uploaded to the
+existing plugin. Hosted MCP tool changes are scanned separately; keep the server
+compatible with currently approved schemas until updates are live. Changing an
+existing MCP URL requires OpenAI support under the current submission flow.
