# boltz Run Boltz structure prediction, molecule and protein screening, and binder design from Claude Code. You’ll need the boltz-api CLI on your PATH and an authenticated account. - plugin · `type=plugin` · Claude Code · ★ 5 - Author: Boltz - License: MIT · policy=mirror · the beginning of the file is at the end of this page - Source: https://github.com/boltz-bio/boltz-api-skills/tree/HEAD/plugins/boltz - Updated: 2026-09-07 - HTML: https://affpapa.org/en/nevibecode/plugins/boltz ## What it does Use the plugin to predict a defined protein–ligand complex, score binding, or rank a SMILES library against a target. It can also generate small-molecule and protein binders, and estimate solubility, permeability, and logD from SMILES. Before submitting a job, the agent prepares its input and shows a cost estimate; results go to `boltz-experiments/`. The plugin includes skills for CLI setup, job status and recovery, molecular screening, and protein design. `boltz-api` must be available on your `PATH`, and you must authenticate with device-code login or an API key. Without both, jobs won’t run. The `boltz-cli-setup` skill can help install or authenticate the CLI. ## Install ### Claude Code (native platform) **Plugin marketplace** In the agent chat (not a shell): ```text /plugin install boltz@claude-plugins-official ``` In the agent chat (not a shell): ```text /plugin marketplace add anthropics/claude-plugins-official ``` ## When to use it - predict a protein–ligand complex structure - score binding against a target - rank a SMILES library by target interaction - estimate ADME properties from SMILES - design peptide or antibody binders ## Example prompts - Predict this protein–ligand complex structure and score its binding. - Rank these SMILES against my target. - Design a peptide binder for this target. ## Source text · boltz · MIT Below is the content of a third-party file.

BEGIN THIRD-PARTY FILE 21b18b7ed448a245 ````text # Boltz Skills Run Boltz biomolecular workflows — structure prediction, binding, molecular and protein screening, and de novo design — directly from your AI coding agent. The skills shell out to the [`boltz-api`](https://install.boltz.bio) CLI to create inputs, estimate cost, submit jobs, and download results. 📖 **Full guide:** [Agent integrations for the Boltz API](https://api.boltz.bio/docs/guides/agent-integrations/) ## Supported agents For Codex and Claude Code, use the official marketplace plugins. Gemini CLI has a native extension, and Claude Desktop uses the MCPB server. [Vercel Skills](https://github.com/vercel-labs/skills) provides an additional way to install the shared skills in Antigravity and other supported agents, or in environments where you prefer a direct skill installation. ## Skills | Skill | What it does | |---|---| | `boltz-cli-setup` | Install, update, verify, and authenticate the `boltz-api` CLI. | | `boltz-structure-and-binding` | Predict the 3D structure of a defined complex; optionally score binding. | | `boltz-small-molecule-screen` | Rank a SMILES library against a target. | | `boltz-small-molecule-design` | Generate novel small-molecule binders. | | `boltz-small-molecule-adme` | Estimate Tier-1 ADME (solubility, permeability, logD) from bare SMILES. | | `boltz-protein-screen` | Rank proteins / peptides / antibodies against a target. | | `boltz-protein-design` | Generate novel peptide / antibody / nanobody / custom-protein binders. | | `boltz-check-status` | List and inspect jobs; recover results after an interrupted session. | ## Prerequisites All surfaces need the `boltz-api` CLI on your `PATH`. **macOS and Linux:** ```sh curl -fsSL https://install.boltz.bio/boltz-api/install.sh | sh ``` **Windows PowerShell:** ```powershell irm https://install.boltz.bio/boltz-api/install.ps1 | iex ``` Verify it: ```sh boltz-api --version ``` Then authenticate, using either device-code login or an API key: ```sh boltz-api auth login --device-code # or export BOLTZ_API_KEY="your-api-key" ``` Results download to a `boltz-experiments/` directory in your working directory (created automatically). Point any command at a different location with `--root-dir`. ## Install ### Codex and Claude Code (recommended: official plugins) For Codex, open the plugin directory, search for **Boltz**, and install the official plugin. In Codex CLI, enter `/plugins` to open the plugin browser. Start a new session after installing. See the [Codex installation guide](surfaces/codex-cli/README.md) for details. For Claude Code, follow the [marketplace installation guide](surfaces/claude-code-cli/README.md). Both plugins use `boltz-api`; complete the prerequisites above or ask for `boltz-cli-setup`. ### Other agents and direct skill installation Use [Vercel Skills](https://github.com/vercel-labs/skills) with Node.js 22.20 or newer. Select your agents and skills interactively: ```sh npx skills add boltz-bio/boltz-api-skills ``` For example, install all eight skills for Gemini CLI in the current project: ```sh npx skills add boltz-bio/boltz-api-skills --skill '*' --agent gemini-cli ``` Add `--global` to make the skills available across projects. Use `--list` to preview the available skills without installing. Use `--copy` if your host cannot use symlinks. Skills installation does not install or authenticate the `boltz-api` CLI; complete the prerequisites above or ask for `boltz-cli-setup`. Use one installation method per agent and scope to avoid loading the same skills twice. Direct Skills installation is optional for Codex and Claude Code; existing marketplace users can keep their plugin installation. To install selected skills, pass their names to `--skill`. Include `boltz-cli-setup` if you need help installing or authenticating the CLI: ```sh npx skills add boltz-bio/boltz-api-skills --skill boltz-cli-setup boltz-protein-design --agent gemini-cli ``` For direct Skills installations, keep the generated `skills-lock.json` with your project. Updates are explicit; review the resulting file changes: ```` END THIRD-PARTY FILE 21b18b7ed448a245 The third-party file has ended.
