Devolens (formerly Cryptolens) Skills

This repository is a bundle of Devolens (formerly Cryptolens) skills intended to be used together, packaged for Claude Code and Codex plugin marketplace installs.

The language-specific skills depend on cryptolens-sdk-common for shared licensing rules, cross-language invariants, and doc-backed guidance that should stay aligned across SDKs. The current layout is bundle-first rather than individually packaged by default, so the ../cryptolens-sdk-common/... links are intentional — all skills live as siblings inside skills/.

Claude Code Marketplace

Install the Devolens plugin from the GitHub marketplace with:

/plugin marketplace add Cryptolens/skills
/plugin install devolens@devolens

Run both commands inside Claude Code. The first registers this repository as a plugin marketplace (reading .claude-plugin/marketplace.json); the second installs the devolens plugin, which bundles all skills under skills/ (cryptolens-sdk-common, the language-specific skills, and the license-* aliases).

To install from a local clone instead of GitHub, point marketplace add at the repository path:

/plugin marketplace add /path/to/skills
/plugin install devolens@devolens

Restart Claude Code after installing so the new skills are discovered.

Codex Marketplace

Review the installer source at:

https://github.com/Cryptolens/skills/blob/main/install.sh

Install the Devolens Codex marketplace with the raw script URL:

curl -fsSL https://raw.githubusercontent.com/Cryptolens/skills/main/install.sh | bash

The installer places a local marketplace at $CODEX_HOME/marketplaces/devolens, defaulting to ~/.codex/marketplaces/devolens when CODEX_HOME is not set. It registers the marketplace in $CODEX_HOME/config.toml so Codex can show Devolens as a marketplace source. On older setups where the config registry cannot be updated, it falls back to the legacy ~/.agents/plugins/marketplace.json path. Restart Codex, open Plugin Directory, choose Devolens, then install Devolens Licensing (devolens).

The Codex installer builds the plugin's skills/ directory from the canonical skills/ bundle during installation. Keep skills/ as the single source of truth.

Skill Layout

Canonical implementation skills (under skills/):

• cryptolens-sdk-common: shared/common skill with cross-language licensing rules and reference material.
• cryptolens-dotnet: .NET-specific guidance, repo mapping, and examples.
• cryptolens-java: Java-specific guidance, repo mapping, and examples.
• cryptolens-python: Python-specific guidance, repo mapping, and examples.

Intent-based alias skills (under skills/):

• license-offline: entrypoint for offline license verification, cached licenses, and air-gapped/manual activation flows.
• license-key-verification: entrypoint for general license key verification and activation flows.
• license-floating: entrypoint for floating-license behavior and overdraft questions.
• license-trials: entrypoint for verified trials and trial-key workflows.
• license-feature-gates: entrypoint for feature-gated licensing, feature templates, and entitlement checks.
• license-subscriptions: entrypoint for subscription expiry checks, renewals, cancellations, and grace periods.
• license-key-generation: entrypoint for backend CreateKey provisioning and license delivery flows.
• license-payment-automation: entrypoint for Stripe, n8n, Zapier, webhook, and external payment-provider automation.

cryptolens-sdk-common is both shared infrastructure for the language-specific skills and a valid standalone skill when the task is language-agnostic, such as explaining product-wide licensing behavior or cross-SDK verification assumptions. The license-* skills are thin SEO/discoverability entrypoints that route into the canonical skills rather than replacing them.

Dependency Model

Use the skills as one bundle unless you explicitly repackage them.
