claude-repath 1.0.0

Migrate Claude Code project state when your project folder moves — rewires cwd paths across sessions, ~/.claude.json, and worktrees.

claude-repath

Rewire Claude Code's local state when your project folder moves.

When you move or rename a project directory, Claude Code loses track of its sessions, memory, todos, and worktrees — because the absolute path is hardcoded in four different places. claude-repath patches all of them in one shot.

---

Why this exists

Claude Code stores per-project state under ~/.claude/projects/<encoded-cwd>/, where the folder name is derived from the project's absolute path. Moving the project folder breaks:

1. ~/.claude/projects/<encoded>/ — the encoded folder name no longer matches
2. ~/.claude/projects/<encoded>/*.jsonl — each session file has "cwd" hardcoded inside
3. ~/.claude.json — the projects key is indexed by absolute path
4. Git worktree sub-projects — each has its own encoded folder AND internal cwd fields

Anthropic has no official migration command (as of 2026-04), and existing community tools cover at most 6 of the needed layers. claude-repath aims to handle all of them, with special care for Windows paths and worktrees.

Install

Pick whichever matches your workflow — they're all equivalent:

Method	Command	When to use
uvx (zero-install)	uvx --from claude-repath claude-repath <subcommand>	Try or use without installing — uv caches it transparently
pipx (global CLI)	pipx install claude-repath	Daily use, isolated from system Python
pip (in a venv)	pip install claude-repath	Already inside a project venv

💡 First time? Run uvx --from claude-repath claude-repath --version — no commitment, just see if it works on your box. Upgrade later with uvx --refresh ….

---

Install as a Claude Code plugin (optional)

In addition to the CLI, this repo ships a Claude Code plugin so your AI assistant can recognize symptoms — "I moved my project and Claude forgot everything", "sessions gone after rename", "~/.claude/projects has the old folder name" — and suggest claude-repath automatically, without you having to remember the tool's name.

From inside Claude Code:

/plugin marketplace add xPeiPeix/claude-repath
/plugin install claude-repath@claude-repath-marketplace

Or, from any terminal (uses the open skills.sh ecosystem — Claude Code, Cursor, Codex, and ~40 more agents):

npx skills add xPeiPeix/claude-repath

The plugin only ships a skill (a ~200-line guidance document). It does not bundle the CLI — you still install that via uvx/pipx/pip above, or let the skill guide Claude to run it via uvx on first use.

Quick start

# INTERACTIVE mode — pick from a list, no path typing needed
claude-repath move

# Explicit mode — preview changes first (ALWAYS recommended)
claude-repath move D:\dev_code\time-blocks D:\dev_code\Life\time-blocks --dry-run

# Actually perform the migration (auto-backs-up first)
claude-repath move D:\dev_code\time-blocks D:\dev_code\Life\time-blocks

# Broader scan — also rewrite cross-project references (use with care)
claude-repath move <old> <new> --scope broad

# Override pre-flight lock check (still bounded by OS-level runtime locks
# — see --force note in Safety section). v0.4.1+ uses atomic os.rename, so
# a runtime lock now fails loudly with the source directory intact; previously
# shutil.move could half-succeed on Windows.
claude-repath move <old> <new> --force

# If you already moved the folder manually, just rewire state
claude-repath rewire D:\dev_code\time-blocks D:\dev_code\Life\time-blocks

# Health check a project's Claude Code state
claude-repath doctor D:\dev_code\time-blocks

# List all projects Claude Code knows about
claude-repath list

# Roll back a previous migration
claude-repath rollback 20260419-155331

What gets migrated

Legend: ✅ fully handled · ⚠️ physically moved but needs manual rebuild · 🔍 diagnosed but not migrated

#	Layer	Status
1	Physical project folder (mv)	✅
2	~/.claude/projects/<encoded>/ directory name	✅
3	.jsonl session files — inline "cwd" fields	✅
4	~/.claude.json — projects key	✅
5	Worktree-derived project folders (auto-discovered)	✅
6	~/.claude/git-worktrees.json (if present)	✅
7	Python .venv/ / venv/ — rebuild after move (why & how)	⚠️
8	node_modules/ — rebuild after move (why & how)	⚠️
9	Chromium Local Storage/leveldb entries (Desktop app)	🔍

⚠️ rows: move physically relocates these directories, but their internal binaries/shims embed absolute paths and stop working until you rebuild with the original package manager. claude-repath detects them pre-flight and prints a non-blocking warning — see Known limitations for the exact rebuild commands.

---

Safety

• Pre-flight lock check (v0.4+): scans every running process via psutil for any that have a cwd inside the target directory or a file open under it, and hard-refuses the migration with exit code 1 if any are found. Reports PID, process name, and specific lock reason (shell cd, IDE, editor, etc.). Overridable with --force / -f.
• Atomic physical move (v0.4.1+): even when the pre-flight check misses a lock (elevated processes invisible to psutil, TOCTOU races, transient AV-scanner or Windows-Search-indexer locks), the physical folder move uses a bare os.rename instead of shutil.move — no silent copytree + rmtree downgrade. Result: on WinError 32 / 5 the move fails loudly with exit code 1 and the source directory is guaranteed intact for retry; the previous half-migration failure mode (target complete, source half-deleted) is now impossible. Cross-volume moves fall back to robocopy /MOVE (Windows) or shutil.move (Unix).
• Dry-run by default logic: destructive commands require either --dry-run preview first or explicit confirmation. Dry-run also previews the pre-flight lock report without blocking.
• Auto-backup: every mutation is snapshotted to ~/.claude/.repath-backups/<timestamp>/.
• Running-Claude warning: soft heads-up if any claude CLI process is detected holding state files (complements the hard pre-flight check above).
• Rollback: claude-repath rollback <timestamp> restores a previous snapshot.

---

Known limitations

Some directories inside a project embed absolute paths at creation time, and no amount of careful copying fixes that — they must be rebuilt after the move. claude-repath move detects the most common offenders and prints a warning (non-blocking) so you know what to rebuild:

Directory	Why it breaks	How to rebuild
Python .venv/ / venv/	Windows Scripts/*.exe trampolines hard-code the path to python.exe; Unix scripts use #!/abs/path shebangs	uv sync / pip install -e . / poetry install — whichever your project uses
node_modules/	.bin/*.cmd shims (Windows) and pnpm symlinks may contain absolute paths	npm ci / pnpm install / yarn install

claude-repath does not run the rebuild for you — every package manager has its own command and auto-running any of them without your consent can clobber lockfiles, pull unexpected versions, or take a long time with no progress feedback. The warning tells you what needs attention; you run the right command.

Other directories with similar issues (target/ for Rust debug builds, vendor/bundle/ for Ruby Bundler, etc.) are currently not detected — flag them via a GitHub issue if you hit problems.

Platform support

OS	CLI state (~/.claude/)	Desktop state (Local Storage/leveldb)
Windows 11 (Git Bash / PowerShell / cmd)	✅ auto-migrated	🔍 diagnosed
macOS	✅ auto-migrated	🔍 diagnosed
Linux	✅ auto-migrated	🔍 diagnosed

Windows paths with drive letters (D:\...) and backslashes are first-class — they were the primary motivation for writing this tool. The path matcher accepts both \ and / separators and automatically aligns with ~/.claude.json's forward-slash-stored keys.

About Claude Code Desktop

Claude Code Desktop stores additional session state in Chromium's Local Storage LevelDB:

• Windows: %LOCALAPPDATA%\claude\Local Storage\leveldb\
• macOS: ~/Library/Application Support/claude/Local Storage/leveldb/
• Linux: ~/.config/claude/Local Storage/leveldb/

claude-repath doctor reports whether this directory exists on your machine but does not migrate it automatically — Desktop's Chromium leveldb format is intentionally out of scope (the schema is private to Anthropic and shifts between Desktop releases, so any auto-migration would be brittle to maintain). If you use Desktop exclusively and move a project, the Desktop UI's "recent projects" list may show a stale path. Remedy: open the new folder via Desktop's File menu to re-register it.

Comparison to existing tools

At the time of writing (April 2026) there is no official Anthropic migration command. A handful of community tools exist — claude-repath is designed to close their gaps:

Tool	Layers covered	Windows	Worktrees	~/.claude.json	Separator tolerance
arak-git/claude-code-project-mover-py	6	✅	partial	✅	partial

Roadmap

• v1.0.0 (current) — Interactive pickers for rollback / doctor + shell-completion auto-install. Both commands previously hard-required a positional argument (rollback <timestamp> meant copy-pasting an encoded folder name from list-backups; doctor <path> required typing the absolute project path). v1.0.0 makes the argument optional and a no-args invocation launches a TUI picker matching move's v0.3.0 wizard style. rollback's picker lists every backup directory under ~/.claude/.repath-backups/ newest-first, each annotated with a humanized date (2026-04-27 15:30:12) parsed from the YYYYMMDD-HHMMSS directory name plus the manifest's entry count (or [unreadable] for corrupted manifests so one bad backup never aborts the picker). doctor's picker reuses pick_project (status filter → orphan detection → conflict markers) but suppresses the Step 1/3 wizard banner and filters out <unknown: ...> placeholder rows so the synthetic string never reaches MigrationContext as if it were a real path. add_completion=True flipped on the typer app exposes claude-repath --install-completion (auto-detects bash / zsh / fish / PowerShell and writes the script into the appropriate rc file) and --show-completion (dumps the script to stdout for manual inspection). pick_project gains keyword-only wizard_step / title / prompt / exclude_unknown parameters so non-wizard callers opt out of the step banner without forking the picker. _read_manifest_entry_count hardens against three previously-unhandled corruption modes: non-dict JSON root (json.loads("[]") returns a list, data.get("entries") was raising AttributeError), missing entries key, and non-UTF-8 bytes (Path.read_text(encoding="utf-8") raises UnicodeDecodeError, a ValueError subclass not in the original (OSError, JSONDecodeError) tuple). New tests/test_cli.py adds 8 typer-CliRunner smoke tests pinning the Argument(None, ...) change against future regressions — particularly the v0.5.1 "PyPI code right but --version wrong" footgun, now caught by test_version_matches_init.
• v0.9.2 — Pre-flight lock scan no longer "looks hung" on Windows. find_locks_on_paths parallelizes the per-process inspection via ThreadPoolExecutor (max_workers = min(32, cpu_count * 4)); psutil's proc.cwd() / proc.open_files() release the GIL on every syscall so plain threads fan out cleanly, compressing 200+ processes × per-handle type-query latency from "10–60 s perceived hang" into single-digit seconds. cli.py additionally emits a permanent ● Pre-flight lock scan stage marker plus a console.status spinner before the scan so the phase is visible in scrollback (matching v0.9.1's ● Moving project folder / ● Rewiring Claude Code state markers). _inspect_process now catches psutil.ZombieProcess (Linux/macOS unreaped children) and OSError at every entry point, including the leading proc.info access — a single transient /proc read failure no longer aborts the whole batch via pool.map. pool.shutdown(wait=True, cancel_futures=True) keeps Ctrl+C latency bounded by the slowest in-flight open_files() call instead of the full process queue. Step 2's Esc-at-name now calls a new _erase_prev_lines(2) helper before re-entering the parent prompt, so repeated Esc cycles overwrite the prior questionary transcript rows in place instead of stacking a growing column. The helper writes to sys.stderr (matching prompt_toolkit's default) and on Windows gates emission on WT_SESSION / TERM_PROGRAM / TERM env-var hints or an explicit GetConsoleMode check for the ENABLE_VIRTUAL_TERMINAL_PROCESSING bit — legacy cmd.exe without VT processing is silently skipped instead of rendering literal ?[F?[2K garbage. TERM=dumb / unknown honored as opt-out.
• v0.9.1 — Single-confirmation migration flow. Step 2's trailing "Confirm the new location?" action menu was collapsed into Step 3's Proceed menu — both previously confirmed the same decision (one over a path, one over the same path plus a plan-count breakdown), which felt like redundant friction. prompt_new_path now returns as soon as parent + name are filled (plus the parent-creation confirm when the parent is missing), and the Step 3 menu absorbs the displaced navigation: ✅ Yes, proceed / ✏️ Edit — re-enter path (Step 2) / ⬅️ Back to project selection (Step 1) / ❌ No, cancel. Also adds explicit stage markers during migration (● Moving project folder / ● Rewiring Claude Code state printed before each phase) — Rich's console.status spinner is live-redrawn and leaves no scrollback trace, so on larger moves users saw a silent gap and suspected a hang. The ● lines stay visible both during and after execution. _step_banner gains a leading blank line for steps > 1 so the Step 3 Panel doesn't abut the tail of Step 2's path-preview output.
• v0.9.0 — Interactive picker now disambiguates duplicate-cwd rows. When two project folders under ~/.claude/projects/ record the same cwd value (classic case: a WSL-launched session at /mnt/d/dev_code encodes as -mnt-d-dev-code/ but its .jsonl entries carry D:\dev_code\x from a later --add-dir / cwd switch, colliding with the native D--dev-code-x/ folder), previously-identical picker rows now gain a dim-yellow ⚠ from: <folder> suffix so you can tell which ~/.claude/projects/<encoded>/ each row lives in. Collision detection scopes to the currently-visible filter bucket — a row visible in isolation stays clean.
• v0.8.2 — Esc still took ~1 s despite v0.8.1 zeroing timeoutlen. Root cause: prompt_toolkit has two escape-timers on Application; v0.8.1 only lowered timeoutlen (multi-key binding wait) but left ttimeoutlen (terminal escape-sequence detection) at the 500 ms default, and the single-Esc path actually hits the latter. Setting ttimeoutlen = 0.01 too makes Esc fire on keydown (~10 ms). Localized via temporary debug instrumentation (CLAUDE_REPATH_DEBUG=1 hook), removed post-fix.
• v0.8.1 — Hotfix pass over v0.8.0: Esc now fires faster (was stuck behind prompt_toolkit's 500 ms escape-timeout despite the eager=True binding — needed to zero out Application.timeoutlen too); crash at Step 1a when the filter prompt returned an empty string (KeyError: '') fixed by routing it through the same _ask_with_back translator; Step-2 banner no longer stacks vertically every time the user cycles through the Edit option (moved the _step_banner + _help_bar calls out of the inner while loop).
• v0.8.0 — Esc = Back shortcut throughout the wizard. Esc at Step 1b's project list returns to the status filter. Esc at Step 2's parent input jumps to Step 1; Esc at the name input loops back to parent (retaining it). Esc at any action menu is equivalent to choosing its "Back" item. Cross-platform — prompt_toolkit's Escape recognition works identically on Windows / macOS / Linux. The help bar in every step now shows Esc back for discoverability.
• v0.7.0 — Interactive wizard gains status filter + bidirectional navigation. Step 1 now opens with a status-bucket menu (🟢 active / 🔴 orphan / ⚪ empty / ❓ unknown / 📋 all, each with counts), so machines with dozens of projects don't force you to paginate through everything to find one. Step 2 adds a live Source→Target path preview plus an action menu — Continue / ✏️ Edit (re-enter with defaults retained) / ⬅️ Back to Step 1 / ❌ Cancel. Step 3 similarly gains a Back option so you can hop back to Step 2 if the plan preview reveals a surprise, instead of Ctrl+C-ing out and restarting. Cursor defaults to active for daily-use flow.
• v0.6.0 — Pre-flight lock check is now project-scoped instead of global. Previously every migration panel-warned on every claude.exe running on the box (10+ unrelated PIDs on multi-project machines, all noise). The check now scans the source project folder plus ~/.claude/projects/<encoded-source>/ — catching only Claude Code sessions actually operating on this project, and closing a prior blind spot where a session actively writing the source project's .jsonl state could be stepped on mid-migration. Unrelated Claude Code windows are correctly ignored. New public API find_locks_on_paths(paths) in claude_repath.locks; the old global detect_claude_processes() and _warn_running_claude() soft-warning are removed.
• v0.5.0 — Interactive TUI picker visual overhaul: grayscale REPATH ASCII splash banner (figlet ansi_shadow, per-line #f0f0f0 → #404040 truecolor gradient), wizard-step icons (📋 pick / 📍 locate / 🚀 confirm), and per-row project-status icons with colored session counts. New 🔴 orphan detection surfaces projects whose resolved cwd no longer exists on disk — the primary migration candidate — so you can see at a glance which projects actually need claude-repath. Sort precedence active > orphan > empty > unknown keeps daily-driver projects at the top, orphans visible just below. New dependency: pyfiglet>=1.0.
• v0.4.2 — Pre-flight warning for path-sensitive subdirectories (.venv / venv with pyvenv.cfg, node_modules). Non-blocking heads-up before move: lists what will need rebuilding at the new location and the per-ecosystem rebuild command, but does not auto-rebuild (auto-running random package managers is risky). New env_warn.py module, new Known limitations section in the README, SKILL.md Edge cases entry so the Claude Code agent can warn users before they run move.
• v0.4.1 — Atomic os.rename replaces shutil.move for the physical folder move; EXDEV cross-volume fallback uses robocopy /MOVE on Windows. Eliminates the Windows half-migration failure mode (source half-deleted + target complete) that the v0.4 pre-flight check could only prevent, not recover from. New PhysicalMoveError with actionable recovery message. --force help text clarifies it cannot bypass OS-level runtime locks.
• v0.4 — Pre-flight lock check (psutil-based scan of running processes for cwd/open_files under the target path, hard-refusing unless --force is passed); Claude Code plugin distribution (installable as a single-plugin marketplace, ships a skill that lets Claude recognize rename symptoms and recommend the tool automatically); TUI picker sorts <unknown> and zero-session projects to the bottom.
• v0.3 — Wizard-style TUI with three-step flow (pick / locate / preview), two-stage path input (parent directory + project name) with Tab-completion, per-layer change counts in a Rich preview panel, and a live spinner during apply.
• v0.2 — Interactive TUI picker, --scope narrow|broad flag, Desktop Local Storage diagnostic, cross-platform path handling (Win/macOS/Linux).
