AI-assisted integration

Devolens offers three ways you can speed up implementation of Devolens:

skill - tells the coding agent exactly how to implement a certain licensing model in your environment. For example, you can ask it to implement key verification in the desired language.
llms.txt - this file provides a summary of our documentation, which includes all documentation articles as well as SDK specific documentation, including the Web API reference.
MCP-endpoint- allows you to retrieve your account data and perform actions on your account. For example, you can use it within your coding agent to e.g. create a new product and troubleshoot errors.

Getting started

Installing the skill

We recommend installing the full skill bundle.

Claude Code
Codex
Other agents

Install from the Claude plugin marketplace:

/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:

Use the license-offline skill to help me add cached offline license verification to this project.

Install the Devolens Codex marketplace:

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 and run scripts/install_codex_marketplace.sh locally.Try:

Use the license-key-verification skill to help me add license key verification with cached offline fallback to this project.

If your agent does not support skills directly, load the llms.txt files below.

Documentation for AI agents (llms.txt)

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

Filename	Summary	When to use
llms.txt (Documentation)	Structured index of the documentation page hosted at help.cryptolens.io.	Answering queries on how to get started with e.g. key verification in different languages, available licensing models and best practises.
llms-full.txt (Documentation)	Completed documentation of all pages hosted at help.cryptolens.io.	When you need the full context (see above).
llms.txt (Web API)	Structured index of the Web API documentation page. It’s language agnostic but provides vital information about each API endpoint.	Answering queries that are not covered by our documentation. This is the source of truth of how the API endpoints work. It’s recommended when you are implementing a license flow not covered by examples, or when you need to implement advanced features, such as “field masking” for privacy/compliance reason, understanding of how to configure access tokens for advanced use cases, and more.
llms-full.txt (Web API)	Completed documentation of the Web API (see above).	When you need the full context (see above).

MCP-endpoint

To give your coding agent account context, you can use our MCP endpoint.
