Hot Updater CLI

Use this skill when a task involves Hot Updater's CLI, hot-updater.config.ts, React Native OTA deployment, patch artifacts, bundle operations, rollback, release-channel management, code signing keys, database migration, fingerprints, or diagnostics.

Operating Rules

• Start from the project root unless the user specifies another app directory.
• Read local hot-updater.config.ts before assuming provider behavior.
• Use npx hot-updater ... for CLI examples and user-facing instructions.
• Do not run npx hot-updater init on behalf of the user. It is interactive and asks for provider, build, and project-specific choices. Guide the user to run it directly and follow the setup documentation.
• Before running npx hot-updater doctor for a server/infrastructure check, make sure the server base URL is available. If the user did not provide it and it is not obvious from local config, ask for the update server URL first.
• For doctor repair loops, run npx hot-updater doctor --json first. Fix issues marked fixability: "auto" by editing local project files, run the listed commands for issues marked fixability: "command", and rerun doctor after each focused change. Stop when doctor passes or the remaining issues are marked fixability: "blocked".
• Treat fixability: "blocked" as outside the autonomous local loop. Server infrastructure remediation commonly needs provider credentials, environment variables, and redeploy access; summarize the blocker instead of running migrations or mutating provider setup.
• Treat deploy, patch, bundle enable, bundle disable, bundle update, bundle delete, bundle promote, rollback, channel set, keys export-public, keys remove, and db migrate as state-changing operations.
• Treat keys generate and db generate as local file/artifact writing operations.
• Use --json only with commands documented here as supporting it. For mutating commands, --json only changes the output format after the requested mutation has already been authorized. If a target project uses an older CLI without that option, fall back to the human-readable output.
• For non-interactive shells, use -y only when the user already requested the exact mutation and the target is unambiguous.
• After mutating bundle state, verify with bundle list or the relevant provider state.
• If deploy fails, stop the deploy workflow. Do not keep retrying fixes, edit setup, change credentials, install dependencies, or run migrations unless the user explicitly asks for that follow-up. Analyze only the failed command, relevant output, likely cause, and suggested next checks.
• Do not edit provider credentials unless the user explicitly asks. Credentials are commonly stored in .env.hotupdater, but projects may use a different environment-loading setup.

Natural Language Requests

Users may invoke this skill with prompts such as:

$hot-updater deploy using the current app version
$hot-updater deploy the current iOS app version to production
$hot-updater roll back the most recently deployed bundle
$hot-updater list iOS bundles on the production channel
$hot-updater update rollout cohort count for bundle <bundle-id> to 500
$hot-updater promote bundle <bundle-id> to staging
$hot-updater create a patch from bundle <old-id> to <new-id>
$hot-updater export the code signing public key
$hot-updater run doctor with server URL https://updates.example.com/api/check-update
$hot-updater fix local doctor issues that do not require server credentials

Translate the request into the safest CLI flow. If a state-changing request is missing a required channel, platform, bundle target, patch base, destination channel, or server URL that cannot be inferred from local context, ask one concise question before mutating anything. For deploy and patch channel, use the CLI default production unless the user names another channel or local context clearly indicates one.

Current App Version Deploy

When the user asks to deploy for the current app version:

1. Run npx hot-updater app-version --json when supported; otherwise run npx hot-updater app-version.
2. Extract ios and/or android from JSON when available, or from the human-readable output as a fallback.
3. If the platform is missing, ask whether to deploy iOS, Android, or both.
4. Deploy with -t <version>:

npx hot-updater deploy -p ios -t <ios-app-version>
npx hot-updater deploy -p android -t <android-app-version>

If deploying both platforms, run one platform at a time and verify each result with npx hot-updater bundle list -p <platform> --limit 5 --json when supported, or without --json as a fallback.

If a deploy command fails, do not continue to the next platform or attempt an automatic repair. Report the failure analysis and wait for a new user request.

Recent Bundle Rollback

When the user asks to roll back the most recent deployment without naming a bundle:

1. Run npx hot-updater bundle list --json --limit 10.
2. Choose the most recent enabled bundle from the JSON result.
3. Use that bundle's channel, platform, and id for a scoped rollback:

npx hot-updater rollback <channel> -p <platform> --target <bundle-id> -y

If the most recent bundle is already disabled, tell the user and ask whether to roll back the next enabled bundle. After rollback, verify with:

npx hot-updater bundle list -c <channel> -p <platform> --limit 5 --json

If --json is unavailable, rerun the same command without --json.

Core Commands

Setup and Diagnostics

npx hot-updater init
npx hot-updater doctor --server-base-url <update-server-url>
npx hot-updater doctor --json
npx hot-updater doctor --server-base-url <update-server-url> --json
npx hot-updater fingerprint
npx hot-updater fingerprint create
npx hot-updater app-version
npx hot-updater app-version --json
npx hot-updater console

• init creates or updates project configuration. Because it is interactive, tell the user to run it directly instead of choosing answers for them.
• doctor checks local setup and server health. Provide --server-base-url; the command appends /version for the server check. If the user has not provided one, ask for it before running the command.
• doctor --json is the preferred agent surface. It returns stable issue codes, related paths, fixability, and command hints for local iterative repair. Do not parse the human-readable doctor output when JSON is available.
• fingerprint and fingerprint create generate the app fingerprint.
• app-version reads native iOS and Android app versions. --json returns { "android": string | null, "ios": string | null } on CLIs that support it.
• console opens the local management console.

Deploy

npx hot-updater deploy -p <ios|android>
npx hot-updater deploy -p ios -c production -r 25
npx hot-updater deploy -p android -f
npx hot-updater deploy -p ios -d
npx hot-updater deploy -p ios -o ./hot-updater-output

Important options:

Patch Artifacts

npx hot-updater patch -b <bundle-id> --base-bundle-id <base-bundle-id> -p ios
npx hot-updater patch -b <bundle-id> --base-bundle-id <base-bundle-id> -p android -c production
npx hot-updater patch -i

Important options:

Bundle Inventory and State

npx hot-updater bundle list
npx hot-updater bundle list -c production -p ios --limit 10
npx hot-updater bundle list -c production -p ios --limit 10 --json
npx hot-updater bundle list --json
npx hot-updater bundle show <bundle-id>
npx hot-updater bundle show <bundle-id> --json
npx hot-updater bundle disable <bundle-id>
npx hot-updater bundle enable <bundle-id>
npx hot-updater bundle update <bundle-id> --rollout-cohort-count 500
npx hot-updater bundle update <bundle-id> --force-update true --json
npx hot-updater bundle update <bundle-id> --target-cohorts 1,2,3
npx hot-updater bundle update <bundle-id> --clear-target-cohorts
npx hot-updater bundle delete <bundle-id>
npx hot-updater bundle promote <bundle-id> -t staging
npx hot-updater bundle promote <bundle-id> -t staging -a move

• bundle list shows the most recent bundles first.
• bundle list --limit <n> defaults to 20.
• --json is available for bundle list, bundle show, and bundle update on CLIs that support it.
• bundle disable and bundle enable read the bundle, mutate enabled state, commit the change, then re-read to verify.
• bundle update can set rollout cohort count from 0 to 1000, force update metadata, and target cohorts.
• bundle delete removes the bundle record by id.
• bundle promote copies to a target channel by default. Use -a move only when the user explicitly wants to keep the same bundle id and move channels.
• In CI or other non-interactive shells, pass -y to enable or disable. Also pass -y to update, delete, or promote only when the requested mutation target is unambiguous.

Rollback

npx hot-updater rollback <channel>
npx hot-updater rollback production -p ios
npx hot-updater rollback production -p ios --target <bundle-id> -y

• Rollback disables the latest enabled bundle on the channel.
• Without -p, rollback applies to both iOS and Android.
• The next most recent enabled bundle on the same channel and platform becomes the fallback.
• If no previous enabled bundle exists, the app falls back to the JavaScript bundle shipped in the native binary.
• Use --target <bundle-id> to retry a partial rollback for exactly one bundle.

Channels

npx hot-updater channel set <channel>

This writes the default channel into native iOS and Android project files. Changing this embedded channel requires a native rebuild.

Code Signing Keys

npx hot-updater keys generate
npx hot-updater keys generate -o ./keys -k 4096
npx hot-updater keys export-public
npx hot-updater keys export-public -i ./keys/private.pem --print-only
npx hot-updater keys remove

• keys generate writes an RSA key pair. The default output directory is ./keys, and supported key sizes are 2048 and 4096 with default 4096.
• keys export-public reads the private key from -i or from signing.privateKeyPath in hot-updater.config.ts, then writes native public key configuration unless --print-only is used.
• keys remove removes public keys from native configuration files.
• Use -y for native file writes only when the user explicitly requested the exact operation.

Database

npx hot-updater db generate [configPath] [outputDir]
npx hot-updater db generate --sql
npx hot-updater db generate --sql postgresql
npx hot-updater db migrate [configPath]

• db generate creates migration output without applying it. The default output directory is hot-updater_migrations.
• db generate --sql [provider] creates a standalone SQL file without reading config. Supported providers are postgresql, mysql, and sqlite; omitting the provider starts interactive selection.
• db migrate applies the latest migration through the configured database plugin.
• Pass -y only when the user explicitly requested the write or migration.
