Even when MCP auth is healthy, Codex wastes tool calls reading the
local workspace (README.md, plugin.json, Get-ChildItem -Recurse)
because the canonical methodology includes pre-flight checks that
read files like `kb/CHANGELOG.md` — those exist in the skill repo
but not in the plugin repo or the plugin install directory.
New section explicitly tells the agent: all methodology and KB
content lives in MCP resources; never read local files to satisfy
methodology steps. The working directory is only relevant when the
user explicitly asks about it.
Complements the Auth-required fallback by addressing the
healthy-MCP-but-still-exploring case.
