lov-cc-mv
Two modes in one tool:
Directory-level (default) — four things in one shot:
mv FROM TO on disk (fs.renameSync — instant, preserves everything)
- Rewrites
~/.claude/projects/<slug>/*.jsonl session store — including every sub-directory slug
- Rewrites
~/.claude/history.jsonl (prompt up-arrow recall)
- Rewrites
~/.claude/sessions/*.json (running-session records)
Session-level (opt-in, via --session/--grep/--pick) — migrate a subset of chats:
- Copies only the selected
.jsonl files from FROM's slug dir into TO's
- Rewrites each file's
cwd from FROM → TO
- Rewrites only the matching running-session records
- Does not touch
history.jsonl or fs mv (project itself isn't being moved)
- Sub-dir slugs are ignored (root only by design)
Old slug dirs and source sessions are left intact unless --delete-source is passed.
When to Trigger
YES — directory-level when:
- User wants to move/rename a project folder (prospective move — we do the mv)
- User already moved the folder externally and CC lost history (post-move recovery — use
--no-mv or the cc-migrate-session alias)
- Sub-dir sessions under FROM should come along (handled automatically)
YES — session-level when:
- User wants to migrate only some sessions from FROM to TO — identified by id, topic/content, or to be picked interactively
- User said "只搬这几个" / "those chats about X" / "not all of them"
- User needs to split one project's chat history across two projects
NO — don't invoke when:
- Renaming a file, function, variable, or branch (not the project root)
- General question about CC's storage model (explain, don't migrate)
- Paths are ambiguous — ask first
Workflow
Step 1 — Gather FROM and TO
| User said |
FROM |
TO |
| "把 /a 搬到 /b" / "mv /a to /b" |
/a |
/b |
| "rename ~/foo to ~/bar" |
~/foo |
~/bar |
| "this project used to be at /old" (cwd is the new location) |
/old |
process.cwd() |
| "本项目已迁移到 /new" (cwd is the old location) |
process.cwd() |
/new |
If either side is ambiguous, ask once with AskUserQuestion. Don't guess.
Always expand ~ and resolve to absolute paths before running the CLI.
Step 2 — Decide directory-level vs session-level
Directory-level if:
- User said "move the whole project" / "rename the folder"
- User wants
fs mv (the folder itself is moving on disk)
- User wants ALL sessions (including any sub-dir sessions) migrated
Session-level if:
- User said "only the sessions about X" / "just these chats" / "not all of them"
- User referenced sessions by content/topic or explicit id
- The folder itself should stay put (only CC state for a subset is moving)
Step 3 — Session-level: resolve the session set
The key design point: AI should auto-filter whenever possible, only prompt the user when ambiguous.
- Run:
``bash npx -y @lovstudio/cc-mv <FROM> --list-sessions --json ``
Parse sessions[*] — each has sessionId, firstUserPrompt, mtime, sizeBytes, messageCount.
- Match the user's intent against
firstUserPrompt yourself:
- If the topic is unambiguous (e.g. "about command vs skill" + exactly one session's prompt obviously matches) → pick it directly, proceed to Step 4 with --session <id> flags. - If a regex captures it cleanly (e.g. topic = "slash command") → use --grep '<pattern>' instead of passing ids. - If multiple sessions could match and you can't disambiguate from firstUserPrompt alone → show the user the shortlist and ask which ones. - If the user asked for interactive picking explicitly → run with --pick and let the CLI do the UX.
- Exclude the current running CC session from the selection — it's the one the user is talking to you from right now, migrating it mid-conversation will break things. (Its
sessionId matches the session file that was written to most recently; safer signal: ask the user to confirm if ambiguous.)
Step 4a — Dry-run + json to preview (directory-level)
npx -y @lovstudio/cc-mv <FROM> <TO> --dry-run --json
Parse the JSON. Tell the user:
- Total sessions and affected slug count (
pairs[*] with sessionCount > 0)
- If
pairs.length > 1: flag that sub-directories also have CC history
- If
toDirExistsOnDisk and FROM also exists: warn — CLI will refuse the fs mv
- If any
pairs[i].toSlugDirExists: warn — destination slug dir will be merged
If totalSessions === 0 AND the user wanted post-move recovery (FROM path doesn't exist): stop, tell them either (a) FROM path is wrong, or (b) CC never ran there.
Step 4b — Dry-run + json to preview (session-level)
npx -y @lovstudio/cc-mv <FROM> <TO> --session <id> --session <id> --dry-run --json
# or
npx -y @lovstudio/cc-mv <FROM> <TO> --grep '<pattern>' --dry-run --json
The JSON's sessionLevel: true, resolvedSessionIds: [...], and pairs[0].sessionFilter: [...] confirm which sessions will move.
Summarize for the user: "Will migrate N session(s): <first-prompt-excerpt of each>". Get confirmation before executing.
Step 5 — Confirm
For directory-level with sub-dirs: ask "Found N sub-dir(s) with CC history. Migrate everything? [Y/n]" — default yes.
For session-level: always summarize the selected sessions (by first-prompt excerpt) and ask "Migrate these N session(s)?" — especially if you resolved them from a regex or topic match, so the user can catch false positives.
Also ask about --delete-source if the user said anything like "move" (vs "copy") — default to keeping source as safety net, only pass --delete-source when the user explicitly wants it.
Step 6 — Execute
Directory-level:
npx -y @lovstudio/cc-mv <FROM> <TO> --yes --json
For post-move recovery (FROM already moved externally):
npx -y @lovstudio/cc-mv <FROM> <TO> --yes --no-mv --json
# OR equivalently:
npx -y @lovstudio/cc-migrate-session <FROM> <TO> --yes --json
Session-level:
npx -y @lovstudio/cc-mv <FROM> <TO> --session <id1> --session <id2> --yes --json
# or with regex:
npx -y @lovstudio/cc-mv <FROM> <TO> --grep '<pattern>' --yes --json
# optionally add --delete-source
Parse phase: "done":
result.slugsMigrated, result.jsonlFilesWritten, result.cwdRewrites
result.historyRewrites (0 in session-level mode — expected)
result.runningSessionRewrites
result.sourceSessionsDeleted (only non-zero with --delete-source)
fsMvMethod: "rename", "shell-mv", or null (session-level / --no-mv)
restartHint.cd + restartHint.command
Step 7 — Tell user to restart CC
Directory-level:
✓ Moved FROM → TO and migrated N session(s) across M slug dir(s).
✓ Also rewrote prompt history and running-session records.
Restart Claude Code in the new location:
cd <TO>
claude --resume
(The old slug dirs at ~/.claude/projects/<old-slug>* are untouched — delete
them once you've verified --resume works.)
Session-level:
✓ Migrated N session(s) from FROM to TO.
✓ Source sessions {kept as safety net | deleted}.
To resume one of the migrated sessions:
cd <TO>
claude --resume <session-id>
IMPORTANT: The CURRENT Claude Code session cannot "switch" its own cwd mid-session. The user must exit and re-invoke claude from the new directory. State this clearly.
CLI Reference
npx -y @lovstudio/cc-mv <FROM> <TO> [options] npx -y @lovstudio/cc-mv <FROM> [<TO>] --list-sessions [--json]
| Option |
Purpose |
-y, --yes |
Skip confirmation prompt |
--dry-run |
Show plan, don't write |
--no-mv |
Skip the filesystem mv (only migrate CC state — post-move recovery) |
--json |
Machine-readable output (use this from the skill) |
--projects-dir <dir> |
Override CC projects dir (default ~/.claude/projects) |
--session <id> |
Session-level: migrate only this id (repeatable) |
--grep <pattern> |
Session-level: migrate sessions whose first user prompt matches the regex (case-insensitive) |
--pick |
Session-level: interactive numbered picker |
--list-sessions |
Print session summaries and exit (pair with --json for scripting) |
--delete-source |
Delete migrated source sessions after copy+rewrite (default keeps them) |
Backwards-compatible alias
npx -y @lovstudio/cc-migrate-session <FROM> <TO> — same tool, but defaults to --no-mv (only migrates CC state, doesn't touch the filesystem). Use when the user already moved the folder externally.
Sub-directory Discovery (directory-level only)
CC's slug rule is: replace every non-[A-Za-z0-9] with -. So FROM/sub slugifies to <fromSlug>-<subSlug>.
The CLI lists ~/.claude/projects/ and takes every slug matching slug === fromSlug || slug.startsWith(fromSlug + "-"). That catches FROM and all descendants in one readdir. It then reads each slug's first jsonl to recover the original absolute sub-path (since slug → path isn't reversible), builds the migration pair, and proceeds.
Session-level mode deliberately ignores sub-dir slugs — the user is cherry-picking sessions, not moving the whole project.
Safety
- Old slug dirs are never deleted in directory-level mode. Copy-then-rewrite. Old state survives.
- Source session files are kept by default in session-level mode. Pass
--delete-source explicitly to remove them.
- fs mv refuses if TO already exists on disk (avoid overwrite).
- Slug-dir merging is default when dest slug dir exists — conflicting jsonls overwritten.
- Session-level +
--mv is rejected (doesn't make sense — the folder itself isn't moving).
- Malformed jsonl lines are passed through unchanged.
Tell the user to verify claude --resume works at TO before rm -rf of old slug dirs.
