Diagnoses + recovers the "every shell command now fails `fatal: Unable to read current working directory: Operation not permitted`" trap, which appears AFTER a git worktree you were running commands in gets removed/pruned mid-session (you merged + deleted its branch, ran `git worktree remove`, or the Claude Code harness auto-cleaned a merged/unchanged worktree). Use when: (1) git AND python both error `Operation not permitted` / `PermissionError: [Errno 1] Operation not permitted` on startup…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Shell pinned to a deleted worktree cwd blocks all git/subprocess work ## Problem Mid-session, a git worktree that your Bash shell is running inside gets removed — you squash-merged + deleted its branch, ran `git worktree remove`, or (most insidiously) the Claude Code harness auto-cleaned the worktree after the branch merged. From that point, **every** `Bash` command's git or python invocation fails: ``` fatal: Unable to read current working directory: Operation not permitted ``` or, from Python: ``` PermissionError: [Errno 1] Operation not permitted ``` The shell's kernel working directory is now a **deleted directory** the OS (macOS especially) refuses to resolve via `getcwd()`. Every subprocess inherits that broken cwd at startup and dies before doing any work. ## Context / Trigger Conditions - The error is `Unable to read current working directory: Operation not permitted` on git, and `PermissionError: [Errno 1] Operation not permitted` on python — at *startup*, before any real work. - **`pwd` lies.** `cd /valid/absolute/path && pwd` prints the valid path, but a `git`/`python` in the …

How to install
mdr add wan-huiyan/agent-traffic-control/shell-pinned-to-deleted-worktree-cwd-blocks-git@sha256:896cb092b00f5948The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
