# AI-assisted integration 

> Use coding agents, skills, and llms.txt files to integrate Devolens faster.

Use AI coding agents to integrate Devolens (formerly Cryptolens) faster.

Install the full Devolens skill bundle rather than a single skill. The language-specific skills depend on `cryptolens-sdk-common`.

<Tabs>
  <Tab title="Claude Code">
    Install from the Claude plugin marketplace:

    ```text theme={null}
    /plugin marketplace add Cryptolens/skills
    /plugin install devolens@devolens
    ```

    This installs all twelve skills in the bundle. To pull new versions later, refresh the marketplace with `/plugin marketplace update devolens`.

    If you need a manual fallback, copy the folders from the repo's `skills/` directory into `.claude/skills/` or `~/.claude/skills/`, then start a new Claude Code session.

    Try:

    ```text theme={null}
    Use the license-offline skill to help me add cached offline license verification to this project.
    ```
  </Tab>

  <Tab title="Codex">
    Install the Devolens Codex marketplace:

    ```bash theme={null}
    curl -fsSL https://raw.githubusercontent.com/Cryptolens/skills/main/install.sh | bash
    ```

    Restart Codex, open Plugin Directory, then install `Devolens Licensing` (`devolens`).

    The installer places a local marketplace at `$CODEX_HOME/marketplaces/devolens`, defaulting to `~/.codex/marketplaces/devolens` when `CODEX_HOME` is not set. It registers `Devolens` as a marketplace source in `$CODEX_HOME/config.toml`. If you prefer not to run the remote script directly, download [github.com/Cryptolens/skills](https://github.com/Cryptolens/skills) and run `scripts/install_codex_marketplace.sh` locally.

    Try:

    ```text theme={null}
    Use the license-key-verification skill to help me add license key verification with cached offline fallback to this project.
    ```
  </Tab>

  <Tab title="Other agents">
    If your agent does not support skills directly, load the `llms.txt` files below.

## Documentation for AI agents

Load these files to give your agent full context of Devolens (formerly Cryptolens) Web API, license models, use cases and best practises.
