ch4570 Codex Agent Runtime — Unsupported
This is an installable negative-contract compatibility skill. It documents that the removed legacy runner
must stay disabled even though this SKILL.md and its inert compatibility script can be discovered.
Call no tools. Do not run a runner script, discovery probe, native subagent, shell command, web request, MCP call, or delegated task. Do not search plugin caches, source checkouts, project paths, user paths, receipts, or environment variables for an executable copy.
Installing this skill copies only its own skill directory and receipt entry. It does not authorize agent execution or create an execution trust root.
If this source skill is invoked directly, return:
AGENT_RUNTIME_ERROR:project_execution_disabled
Use the host's normal reviewed coding workflow for the user's actual task. Do not present repository catalog metadata as installed, discovered, or executable runtime state.
