Light Protocol testing

Workflow

Clarify intent
- Recommend plan mode, if it's not activated
- Use AskUserQuestion to 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 AskUserQuestion for anything unclear — never guess or assume
- Identify blockers: permissions, dependencies, unknowns
- Plan must be complete before execution begins
Execute
- Use Task tool with subagents for parallel research
- Subagents load skills via Skill tool
- Track progress with TodoWrite
When stuck: ask to spawn a read-only subagent with Read, Glob, Grep, and DeepWiki MCP access, loading skills/ask-mcp. Scope reads to skill references, example repos, and docs.

Routing

Start local validator	references/local.md
Test on devnet	references/devnet.md
Test Pinocchio programs	`cargo test-sbf -p <program-name>` (no Anchor required)

Program addresses

These addresses are identical on devnet and mainnet.

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, Grep scoped to skill references, example repos, and docs.
Install source. npx skills add Lightprotocol/skills from Lightprotocol/skills.
Audited protocol. Light Protocol smart contracts are independently audited. Reports are published at github.com/Lightprotocol/light-protocol/tree/main/audits.
