The /custom/ layer is a template: in upstream microsoft/BCQuality it stays empty by default and is meant to be populated only inside a fork or consumer clone. PR #55 both targeted /custom/ and leaked a new top-level folder. - skills/write.md: add a fork-precondition guard so authors (human or agent) confirm they are not in microsoft/BCQuality before scaffolding /custom/ content. - Guard custom layer workflow: auto-closes upstream PRs that add/modify /custom/ content beyond the template files, with a friendly redirect-to-fork comment. - Flag new top-level entries workflow: posts an advisory (non-blocking) comment when a PR introduces an unexpected top-level folder or file for maintainer review. Both workflows run only on microsoft/BCQuality (never on forks) and read the PR file list via the API without checking out or executing PR code.

# The /custom/ layer is a template: in upstream microsoft/BCQuality it stays
|
|
# empty by default (README.md + .gitkeep placeholders only). Custom knowledge
|
|
# and skills are partner/customer-specific and belong in a fork, never upstream.
|
|
#
|
|
# This workflow auto-closes any PR that adds or changes content under /custom/
|
|
# (anything beyond the allowed template files). It runs only on the upstream
|
|
# repo, so forks that legitimately populate /custom/ are unaffected.
|
|
#
|
|
# pull_request_target is required so the workflow runs with a token that can
|
|
# comment on and close the PR (including PRs opened from forks). It only reads
|
|
# the PR's file LIST via the API and never checks out or executes PR code, so
|
|
# the elevated token is not exposed to untrusted content.
