Summon

Copy (or move) Claude Desktop Code-tab sessions across accounts so they're visible from the account you switch to next. Full transcripts intact; no API calls; no summarisation.

When to run it

Before you switch accounts, not after. The natural workflow:

Notice you're approaching usage limit on the account you're currently using
Run summon --to <next-account> — sessions get copied (default) into the next account's dir
Logout from current account in Desktop → Login to the new account
All your mid-flight sessions appear in the new account's left-hand session picker (the sidebar on the left side of Desktop's Code tab). The Logout/Login is the natural switch you were going to do anyway.

Running summon after hitting the usage limit also works — the file moves are pure local ops, no API needed — but you'll still need to Logout/Login on the destination to see the sessions, since Desktop's session list is cached at login. Doing it proactively just means the Logout/Login is no longer "extra friction," it's the same step you'd be doing anyway.

Mental model

Each Desktop session has two halves:

Half	Location	Account-bound?
Metadata JSON	`%APPDATA%/Claude/claude-code-sessions/<account>/<workspace>/local_<uuid>.json`	Yes — lives under `<account>`
Transcript JSONL	`~/.claude/projects/<encoded-cwd>/<cli-uuid>.jsonl`	No — global, shared

Summon copies (or with --move, relocates) the metadata wrapper into the destination account's dir. The transcript stays put — both wrappers point at the same conversation. After Logout/Login on the destination, the new entries appear in the left-hand session picker (Desktop's Code-tab sidebar).

Run

# Wrapper (after install — see below)
summon [flags]

# Or direct
python ~/.claude/skills/summon/scripts/summon.py [flags]

Default behaviour: list candidate sessions across all non-destination accounts, grouped Account → Project → Session, then prompt to copy them into the destination account. Copy semantics by default — sessions remain visible in the source account too. Last 3 days; remote-VM sessions auto-skipped.

Two natural framings of the same operation:

Push (proactive): you're approaching usage limit on your current account. Run summon --to <next-account> while still on the current one. Pick which sessions to push. Then Logout/Login is the account switch you were going to do anyway.
Pull (rescue): you've already switched accounts and want to bring earlier sessions over. Run summon (no --to); destination defaults to your now-current account.

Mechanically identical — the file moves are the same regardless of which framing you have in mind. Push is the recommended workflow because the Logout/Login becomes invisible.

Flags

Flag	Default	Effect
`--to <account>`	most-recently-active account	Destination — where the sessions land. Specify when pushing to a different account; omit when pulling into your current account. UUID prefix or email substring
`--from <account>`	all non-destination accounts	Restrict source to one account
`--days N`	3	Time window
`--all`		Disable time filter
`--cwd <pattern>`		Substring match against session cwd
`--title <pattern>`		Substring match against session title
`--pick`		Interactive multi-select by number
`--move`		Move instead of copy — delete source after copying (lean cleanup)
`--dry-run`		Preview without touching files
`--list-accounts`		Show all accounts and exit
`--peek <id>`		Preview a session's last messages and exit (id prefix or full)
`--flat`		Flat list instead of grouped hierarchy
`--yes`		Skip confirmation prompt

Auto-detect rules

Destination: account with the most recent filesystem activity (mtime of any session JSON). This reliably tracks the active Desktop account.
Source: by default, all accounts except destination. Use --from <account> to restrict to one.
Workspace dir under destination: most-recently-active existing workspace. New UUID is created if the destination has no workspaces yet.

Display

Output follows the Terminal Panel Design System (panel header, body with │ rail, footer, ASCII fallback when stdout isn't UTF-8). The candidate hierarchy is Account → Project → Session, with sessions globally numbered for picker selection (3, 5, 7).

Header shows → destination. Summary line shows count, source breadth, and active filter window. Body shows Account → Project → Session hierarchy with global numbering for picker selection (3,5,7). A rotating hint tile sits above the footer; the footer shows the active hotkeys.

Edge cases handled

Case	Behaviour
Session cwd is `/sessions/<vm>/mnt` (remote)	Skipped — no local transcript to bridge
Transcript JSONL missing on disk	Skipped with warning (orphan metadata)
Same `sessionId` already in destination	Skipped (idempotent)
Destination has no workspace dirs	New workspace UUID created
Stdout is not UTF-8 (Windows cp1252)	ASCII fallback for all panel glyphs
Stdout is not a TTY or `NO_COLOR` set	Plain text, no ANSI escapes

Sidebar refresh

Desktop loads sessions into its left-hand session picker on login and doesn't watch the filesystem afterwards (verified via bundle inspection — no chokidar, no relevant fs.watch on the session dir, only direct fs.readdir calls). Summon throws a best-effort nudge at fs.watch (sentinel pings, mtime touches, rename ping-pong) but don't rely on it — assume Logout/Login is required to populate the sidebar with new sessions.

This is why summon is best run before switching accounts: the Logout/Login is what you'd do anyway. Running summon as a "rescue" after the fact still works mechanically, but the Logout/Login still has to happen.

If sessions still don't appear:

Try View → Reload (rarely helps; Ctrl+R only re-renders)
Logout → Login triggers a full filesystem rescan and always works

Wrapper install

Symlink (or copy) the wrapper into a directory on PATH:

# Linux/macOS/Git Bash
ln -s ~/.claude/skills/summon/bin/summon ~/.local/bin/summon

# Windows (PowerShell)
copy "$env:USERPROFILE\.claude\skills\summon\bin\summon.cmd" "$env:USERPROFILE\bin\summon.cmd"

Then summon --pick works directly from any shell.

Architecture reference

Full file system layout, session schemas, account binding, and the validated cross-account transfer procedure live in docs/references/claude-desktop-internals.md (claude-mods). That document is canonical; this skill is the operating manual.

Anti-patterns

Waiting until you've already hit the limit — the file moves still work, but you've burned the chance to wrap up your current message before switching. Run summon proactively while you still have usage on the source.
Expecting sessions to appear in the sidebar without Logout/Login — Desktop's session list is loaded on login; the kitchen-sink fs.watch nudge is best-effort and shouldn't be relied on. The Logout/Login becomes painless if you've timed summon as a push before switching.
Running while Desktop is mid-write to a session JSON — quit Desktop first if you've literally just closed the session you want to push.
Trying to summon remote sessions — they have no local transcript and can't be transferred.
Hardcoding account UUIDs — use --list-accounts first, then email substring (more readable, less brittle).
Treating this as a transfer for archived sessions — it's for mid-flight work; archived sessions belong in the source account's archive view.
Using --move for sessions you might want to access from both accounts — copy is default precisely because multi-account workflows are the common case.
