What problem does it solve? Agents editing the CG-agent-harness repository can act on stale documentation or touch security-critical code without knowing the project's truth order, invariants, and quality bar. This Skill orients an agent before substantive repository work so changes follow the correct sources and gates. ## Core Features & Use Cases - Truth Order Enforcement: Establishes that code under src/ and assets/config.default.yaml outrank prose docs, and requires doc fixes in the same change set when behavior changes. - Task-to-Source Mapping: Tables map tasks (shim/I6, HTTP guards, write gates, clone jail, config, routes, packaging) to the exact files and tests to read first. - Skill Routing & Quality Bar: Directs which companion skill to load next (verify, invariant-guard, config-guard, release, etc.) and lists the mandatory checks: cargo fmt, clippy -D warnings, cargo test, and cargo deny check. - Use Case: Before modifying the write-gate path, an agent loads this Skill, reads src/agentic/writer.rs and the write-gate sections of INVARIANTS.md, then routes to the write-policy-redteam skill. ## Quick Start Ask the agent to load the cgagentharness-project-guidance skill before starting substantive work on the CG-agent-harness repository.
