One command for Claude Code, Cursor, Codex, Windsurf and other agents — installs from the upstream repo (current HEAD; it ships 5 skills — pick testing when prompted).
Drop the mirrored SKILL.md into your skills directory. Global (all projects):
Or scoped to the current project:
This skill references companion files (4) that stay on GitHub — links in the mirror point there, pinned to the indexed commit. For the full offline bundle use the CLI or Git tab.
The skill is mirrored as plain markdown — tell your agent:
Or have the skills CLI generate a one-shot prompt (pipe it straight into your agent):
Or pull the raw file into a terminal session:
Copy the skill directory with all companion files straight from GitHub:
Skill contents
Light Protocol testing
Workflow
- Clarify intent
- Recommend plan mode, if it’s not activated
- Use
AskUserQuestionto resolve blind spots - All questions must be resolved before execution
- Identify references and skills
- Match task to test references below
- Locate relevant documentation and examples
- Write plan file (YAML task format)
- Use
AskUserQuestionfor anything unclear — never guess or assume - Identify blockers: permissions, dependencies, unknowns
- Plan must be complete before execution begins
- Use
- Execute
- Use
Tasktool with subagents for parallel research - Subagents load skills via
Skilltool - Track progress with
TodoWrite
- Use
- When stuck: ask to spawn a read-only subagent with
Read,Glob,Grep, and DeepWiki MCP access, loadingskills/ask-mcp. Scope reads to skill references, example repos, and docs.

Security
This skill provides test patterns and configuration references only.
- Declared dependencies. Devnet testing requires
HELIUS_API_KEY(RPC provider key). Localnet testing needs no credentials. In production, load from a secrets manager. - Subagent scope. When stuck, the skill asks to spawn a read-only subagent with
Read,Glob,Grepscoped to skill references, example repos, and docs. - Install source.
npx skills add Lightprotocol/skillsfrom Lightprotocol/skills. - Audited protocol. Light Protocol smart contracts are independently audited. Reports are published at github.com/Lightprotocol/light-protocol/tree/main/audits.
