Operate the optional `grace` CLI against a GRACE project. Use when you want to lint GRACE artifacts, explain/remediate lint issues, check autonomy readiness, inspect project or module health, inspect verification entries, resolve modules from names or file paths, inspect shared/public module context, or inspect file-local/private markup through `grace lint`, `grace status`, `grace module`, `grace verification`, and `grace file show`.

Complete GRACE methodology reference. Use when explaining GRACE to users, onboarding new projects, or when you need to understand the GRACE framework - its principles, semantic markup, knowledge graphs, contracts, testing, and unique tag conventions.

Debug an issue using GRACE semantic navigation. Use when encountering bugs, errors, or unexpected behavior - navigate through the graph, verification plan, and semantic blocks to analyze the mismatch and apply a targeted fix.

Design and enforce testing, traces, and log-driven verification for a GRACE project. Use when modules need stronger automated tests, execution-trace checks, or a maintained verification-plan.xml that autonomous and multi-agent workflows can trust.
