Terrazul CLI (`tz`)

npm i -g @terrazul/tz

Terrazul CLI is the package manager for AI agent configurations. Easily build, run and share agent configurations for Claude Code, Codex and Gemini CLI.

---

Quickstart

Install tz

pnpm / npm (when published)

pnpm i -g @terrazul/tz
# or
npm i -g @terrazul/tz

Why Terrazul CLI

• Production ready: Run battle tested agentic configurations that adapt to your projects with context-aware rendering.
• Multi-tool support: Generates Claude Code, Codex and Gemini CLI, with a single install step.
• Offline-first: Local cache mirrors upstream packages so rebuilds succeed without a network connection.
• Team-friendly: Adopt consistent AI workflows across your team by publishing private packages.

---

Key Concepts & Files

• agents.toml: Project manifest with dependencies, compatibility rules, and profiles.
• agent_modules/: Extracted package payloads linked into local tool directories.
• ~/.terrazul/cache/ and ~/.terrazul/store/: Content-addressable caches for fast reinstalls.
• TERRAZUL.md: Human-readable snapshot of the active manifest, regenerated on every install/update.

---

Command Tour

• tz init: Bootstrap manifests, .gitignore, and optional Claude scaffolding.
• tz add <pkg@range>: Resolve, verify, and extract packages; updates profiles and lockfile.
• tz install: Install every dependency declared in agents.toml, refresh the lockfile, and render templates.
• tz update [pkg]: Plan or apply upgrades to the latest compatible non-yanked versions.
• tz uninstall <pkg>: Remove packages, clean symlinks, prune profiles, and refresh docs.
• tz run -- [args...]: Launch integrations (e.g., Claude Code) with generated MCP configs and optional profiles.
• tz extract: Launches an Ink-powered wizard (TTY default) to select artifacts and MCP servers; add --no-interactive for script-friendly flag mode.
• tz cache prefetch: Download SEA binaries for specific targets into ~/.terrazul/cache/sea so cold starts work offline.
• tz link / tz unlink: Register local development packages and swap between linked and registry versions.
• tz env *: Manage registry endpoints and active environments without editing config files.
• tz auth login|logout: Manage tokens per environment.

See tz --help for the full command catalog and flags.

tz extract Wizard Layout

• Top bar conveys the wizard name, step progress, and verb-oriented title (e.g., Extract • Step 3/6 — Choose Output Directory).
• Body opens with concise instructions and structured content (selection lists, counters, validation hints).
• Action bar keeps the primary action first (Enter • Continue or Enter • Extract package) and lists secondary shortcuts in a stable order (Shift+Tab, Space, A, N, V, ?, C).
• Status bar only appears during background work, animating a spinner while analyzing or executing plans.
• Log drawer starts hidden; press V to reveal recent log lines or hide them again.
• Review step groups artifacts, MCP servers, and destination with counts and offers a clipboard-friendly summary via C.

Template Snippets: askUser & askAgent

Templates can gather inputs interactively using askUser (prompts the user) and askAgent (calls AI tools):

• Inline prompts: {{ askUser('Question?') }} and {{ askAgent('Prompt text') }}. Both support whitespace trimming (~ / -) and can appear inline or within blocks.
• Variable capture: {{ var summary = askAgent('Prompt', { json: true }) }} stores the result under vars.summary for later reuse.
• Options: askUser accepts { default, placeholder }. askAgent accepts { json, tool, schema, safeMode, timeoutMs }.
• Multi-line prompts: Use triple quotes for askAgent: {{ askAgent("""Multi-line prompt here""") }}.
• Interpolation: Access captured variables in prompts: {{ askAgent('Summarize: {{ vars.userInput }}') }}.

Example

{{~ var projectName = askUser('Project name?', { default: 'My Project' }) ~}}
{{~ var summary = askAgent("""
Analyze the repository and provide a brief summary.
Project: {{ vars.projectName }}
""", { json: true }) ~}}

# {{{ vars.projectName }}}
{{{ vars.summary.result }}}

See packages/mattheu-ctx-default/templates/CLAUDE.md.hbs for a complete example.

Switch registries & authenticate

# List known registries and the active target
tz env list

# Point at staging (https://staging.api.terrazul.com)
tz env use staging

# Log in (supports ChatGPT token or API key)
tz auth login

Tokens are stored per environment in ~/.terrazul/config.json with 0600 permissions. Use tz env commands to rotate between staging, production, or local dummy registries without editing the config file by hand.

Configure staging in ~/.terrazul/config.json

If you prefer to edit the config directly, create ~/.terrazul/config.json (or update the existing file) with the staging registry URL and cache defaults:

{
  "registry": "https://staging.api.terrazul.com",
  "token": "tz_eM94WWtBUtF1DbuojEOvRko1TU088vIK",
  "cache": { "ttl": 3600, "maxSize": 500 },
  "telemetry": false
}

Restart any running tz processes so they reload the updated configuration. Future tz env use commands will migrate this legacy single-registry config into the newer environment-aware layout automatically.

Built-in safety nets

• Every destructive operation (install overwrite, update with --apply-force, apply with --force) snapshots files into .tz-backup/<timestamp>/... at your project root.
• Lockfiles capture exact tarball hashes (sha256-<base64>) to guarantee reproducible installs, even offline.

Local Development

This directory builds the CLI distributed in releases. Clone the repo and run:

pnpm install
pnpm run build     # produces dist/tz.mjs (ESM bundle with shebang & require shim)
pnpm test          # vitest suite (unit + integration scaffolding)
pnpm run lint      # ESLint (max warnings = 0)
pnpm run format    # Prettier
pnpm run test:sea  # optional: smoke the Node SEA workflow

To install a local SEA binary for manual testing:

pnpm run sea:install -- --as tz --dest /usr/local/bin

SEA release verification

• Staged npm packages now target Node 20+. The release workflow rewrites engines.node to >=20.0.0 and ships an ESM launcher (bin/app.mjs).

• Run the local verification tool before publishing to confirm metadata, compressed assets, and launcher compatibility:

  pnpm tsx tools/verify-sea-package.ts \
  --release-version 0.0.0-dev \
  --run-id <gha-run-id> \
  --workflow-url https://github.com/terrazul-ai/terrazul/actions/runs/<gha-run-id> \
  --gh $(pwd)/path/to/gh-stub-or-binary \
  --node20 $(nvm which 20)

  Use --keep-stage to inspect the staged package directory and --skip-launch if the current platform binary is unavailable.

• workflow_dispatch runs of cli-sea-release.yml perform staging and smoke tests but intentionally skip the final npm publish step.

Any semantic commit that touches cli/ triggers CI to lint, build, test, and produce release artifacts.

---

SEA Distribution Basics

• SEA binaries are downloaded on demand. The first launcher execution fetches the {platform, arch} binary described in dist/manifest.json, verifies its SHA-256, decompresses it into ~/.terrazul/cache/sea/<version>/<target>/, and reuses the cached copy for future runs (including fully offline invocations).
• GitHub Releases host the authoritative compressed binaries plus manifest.json. The manifest provides deterministic URLs, sizes, and digests so provenance checks remain intact.
• Administrators can pre-seed caches on CI agents or air-gapped environments with tz cache prefetch --targets linux-x64,win32-x64 and copy the populated cache directory.
• Override paths during testing or CI with TERRAZUL_SEA_MANIFEST, TERRAZUL_SEA_CACHE_DIR, and TERRAZUL_SEA_BASE_URL. See docs/sea-distribution.md for advanced usage and troubleshooting.

• For staging token resets or registry access, reach out through your Terrazul support channel.
• Join internal Terrazul Slack #cli for roadmap updates and release coordination.

---

License

Licensing will be published alongside the first public release. Until then, Terrazul CLI is available for internal evaluation only.

---

Release Automation

• Release Please runs on pushes to main that touch cli/ using the RELEASE_PLEASE_TOKEN PAT so downstream SEA packaging and npm publish fire automatically.
• To cut a new release, land at least one conventional commit under cli/, merge the generated chore(main): release … PR, and let the automation handle tagging plus artifact publication.
• After the release workflow completes, verify the new bundle locally with node dist/tz.mjs --version; it should print the tag that was just published.
