cargo clippy -- -D warnings    # Run linter

# Testing
cargo test                     # Run all tests (unit + e2e)
cargo test --test e2e          # Run e2e tests only
cargo test --lib               # Run unit tests only

# CLI
glm-plan-usage init            # Initialize config
glm-plan-usage print           # Print current config

Standards

MUST FOLLOW THESE RULES, NO EXCEPTIONS

• Graceful degradation: the plugin must never cause Claude Code to fail. All segments return Option<SegmentData>, never panic.
• All config fields must have #[serde(default)] to allow adding new fields without breaking existing configs.
• Silent by default: no stderr output unless --verbose is set. API failures return None, not errors.
• Only add meaningful comments explaining why (not what) something is done.
