Read and follow `../../../.claude/skills/runtime-canary/SKILL.md`, a path relative to this file, as the authoritative workflow.
Run its commands from the repository root, the folder that holds `.agents` and `.claude`, and resolve every relative path it names from there.
A command that writes a shim under `.agents` needs an approval to run outside Codex's sandbox, which keeps `.agents` read-only.
