CLAUDE_INGEST_SKIP_PROJECTS takes filepath.Match globs tested against
the project directory NAME, and a matching directory is skipped during
the directory WALK — so its files are never opened and their content
never enters the process. That is a stronger property than filtering
after reading, and the difference is observable: without SkipDir,
WalkDir lists the directory's entries, and an unreadable one aborts the
entire walk, silently stopping ingestion for every other project.
Globs rather than exact names because a project directory is derived
from the session's working directory, so a git worktree yields an
ephemeral name no exact-match list could keep up with.
An unparseable pattern refuses to run. filepath.Match returns an error
ALONGSIDE a false match, so a bad pattern checked per-file would ingest
the directory while the log complained — the failure nobody notices.
Validated once, up front, in both entry points.
This complements the client-name scrubber rather than replacing it. The
scrubber drops individual turns whose content matches a client
identity; this excludes whole workspaces whose content is confidential
in ways no pattern reliably recognises. Learnings from excluded
sessions are captured deliberately through the session-close ritual
instead.
Recorded caveat: the project directory reflects the session's working
directory, NOT the repositories it touches. A session run from ~/dev
that reads an excluded repo is not excluded by this. The scrubber
remains the control for content; this is a control for workspaces.
A mutation test earned the strongest assertion here: the original tests
could not distinguish SkipDir from filtering after the walk, because
neither opens files. The unreadable-directory test can.
