# Verify Marketplace > Drive the duyet/codex-claude-plugins marketplace pack via control-marketplace: marketplace JSON, Claude/Codex/Antigravity/Grok manifests, local plugin logos, and documented install paths. Use when verifying plugin catalog changes, install docs, or scripts/validate-plugins.sh. There is no hosted web UI. - Skill: `duyet/verify-marketplace` (Agent Skill, multi-file: 14 files) - Install (CLI): `npx skillmds@latest add duyet/verify-marketplace` - Raw SKILL.md: https://api.skillmd.com/api/skills/duyet/verify-marketplace/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Coding & Dev Tools - Author: duyet (https://skillmd.com/u/duyet) - Updated: 2026-09-09 - Page: https://skillmd.com/skills/duyet/verify-marketplace --- # Verify marketplace Drive this checkout as a **plugin marketplace pack**, not a web app. Users add a marketplace and install plugins in Claude Code, Codex, Grok Build, or Grok Bot. The lever is `control-marketplace.mjs`. `--help` is canonical. ```bash node .cursor/skills/verify-marketplace/control-marketplace.mjs --help ``` ## Surface (interview) - **Primary:** catalogs and manifests on disk (`marketplace.json`, `.claude-plugin/marketplace.json`, `.agents/plugins/marketplace.json`, `.grok-plugin/marketplace.json`, per-plugin `.claude-plugin/plugin.json`, `.codex-plugin/plugin.json`, `.grok-plugin/plugin.json`, and `.grok-build-plugin/plugin.json`). - **Install docs:** root `README.md`, `CLAUDE.md`, `CONTRIBUTING.md`. - **Logos:** each plugin's `assets/logo.svg`, plus marketplace `logo` paths relative to the plugin source directory. - **Existing harness:** `bash scripts/validate-plugins.sh` (same script CI runs). - **Also present:** `scripts/install-antigravity.sh` for the one plugin that ships `.antigravity-plugin/plugin.json`. - **Not present:** hosted UI. Do not open a browser against this repo. Drive Grok Build and Grok Bot with `check-install --surface grok`. Skip is a failure. ## Launch There is no server. Launch means: this git checkout, `python3`, and Node. ```bash node .cursor/skills/verify-marketplace/control-marketplace.mjs doctor --json ``` Ready when `ok` is true and `checks` all pass. Teardown is not required for read-only commands. Two agents may run read-only commands in the same checkout. Do not create git worktrees for verification. ## Doctor Run first when anything looks off: ```bash node .cursor/skills/verify-marketplace/control-marketplace.mjs doctor node .cursor/skills/verify-marketplace/control-marketplace.mjs doctor --json ``` Doctor answers "is this instance worth driving?": marketplace JSON parses (including `.grok-plugin/marketplace.json`), `scripts/validate-plugins.sh` exists, plugin directories are visible, python3 works. Catalog drift (for example a plugin missing from the Codex or Grok marketplace) is **not** a doctor failure; `validate` and `check-install --surface codex|grok` report that. ## Drive Match the change to a file under [`references/features/`](references/features/). Then run the commands that file lists. Compose with `--json` and `jq`. ```bash # identity and inventory node .cursor/skills/verify-marketplace/control-marketplace.mjs info --json node .cursor/skills/verify-marketplace/control-marketplace.mjs list --json node .cursor/skills/verify-marketplace/control-marketplace.mjs inspect commit --json # production validator (CI equivalent) node .cursor/skills/verify-marketplace/control-marketplace.mjs validate --json # docs + install resolvability node .cursor/skills/verify-marketplace/control-marketplace.mjs check-docs --json node .cursor/skills/verify-marketplace/control-marketplace.mjs check-install --surface claude --json node .cursor/skills/verify-marketplace/control-marketplace.mjs check-install --surface codex --json node .cursor/skills/verify-marketplace/control-marketplace.mjs check-install --surface grok --json # Grok Bot + Grok Build proven drive (skip is a failure) node .cursor/skills/verify-marketplace/control-marketplace.mjs prove --feature grok-build-and-bot --json # destructive Antigravity symlink plan only node .cursor/skills/verify-marketplace/control-marketplace.mjs install-antigravity --dry-run --json ``` Prefer these handles over reading source: marketplace `name` / `source` / `source.path`, manifest `name`+`version`+`description`, README install commands. ## Evidence Proof lives under `.cursor/skills/verify-marketplace/proof/` unless `--out` says otherwise. Cleanup must not delete it. Standards: - Exercise the real user path: documented install commands and the files those commands would resolve, plus `scripts/validate-plugins.sh`. Do not treat "the JSON looks fine" as proof that a `source` path exists. - Capture the command and the resulting `ok` / failed check ids, not only a final summary. - Side effects: for `install-antigravity --dry-run`, observe that the target directory is unchanged (no new symlinks). Do not trust the flag name alone. - Mocks: none. This pack is files on disk. - Hosted UI screenshots are not evidence here; there is nothing to screenshot. Record a drive: ```bash node .cursor/skills/verify-marketplace/control-marketplace.mjs prove --feature marketplace-catalog --json node .cursor/skills/verify-marketplace/control-marketplace.mjs prove --feature grok-build-and-bot --json ``` ## Cleanup ```bash node .cursor/skills/verify-marketplace/control-marketplace.mjs cleanup --dry-run --json node .cursor/skills/verify-marketplace/control-marketplace.mjs cleanup --json ``` Removes `/tmp/verify-marketplace-*` only. Never kill processes by name. Never delete `proof/`. After cleanup, `proof/drive.json` must still exist. ## Helpers The only helper is `control-marketplace.mjs` in this directory. It is executable. `--help` and ` --help` document flags. Destructive command: `install-antigravity` (writes symlinks) and `cleanup` (deletes tmp scratch); both accept `--dry-run`. `install-antigravity` is dry-run unless `--apply` is passed, and it refuses the default `$HOME/.gemini/config/plugins` target without `--force`. ## Feature map [`references/features/README.md`](references/features/README.md) is the regression index. Each feature file uses `Sub-features`, `How to get to it (user POV)`, `Driving it with control-marketplace`, `Gotchas`. Keep the map honest with `/maintain-verification-skill` as catalogs grow.
