Draft — the content is settled, but it is worth a read before it goes in, since two of the paragraphs are new claims about behaviour rather than restatements.

#160 shipped shared auto-memory without touching the README, so the Multi-Account Support section still describes cross-account sharing as symlink-or-copy only. This adds the missing parts and fixes two statements that turned out to be wrong or imprecise.

What was missing

  • codev account share-memory <name> on|off was absent from the CLI table.
  • The shareable-items table had no row for auto-memory.
  • The Sharing paragraph offers "three choices: Link, Copy, or skip", which no longer covers the panel — there is now a checkbox that is neither.

The new Shared auto-memory subsection says what is shared (auto-memory for the project the session starts in), what is not (session transcripts, which is what keeps CodeV's per-account session attribution working), and which of the launch paths carry the redirect. That last one matters in practice: a session started by a bare CLAUDE_CONFIG_DIR=… claude or by the VS Code extension keeps using that account's own memory, and nothing warns you.

The reason it needed prose beside the table rather than one more ✅ row is that this mechanism is not a symlink like the rows above it. It is a --settings redirect computed per launch, so nothing is written into the repository and neither account's settings.json is touched.

Two corrections

"CodeV refreshes accounts.sh on every launch" is packaged-only. The sync returns early unless app.isPackaged, so yarn start never rewrites the file. The consequence is worth stating explicitly because it is silent: regenerate from a newer checkout with yarn account regenerate, then launch an older installed CodeV, and the older app's bundled template replaces the file. The registry still holds what you configured, but the generated shell functions are the old ones — which is exactly how a configured account can stop behaving as configured with nothing to show for it.

cmux replaces the dispatcher. cmux's shell integration installs its own claude wrapper after ~/.zshrc is read, so claude <name> in a cmux pane does not switch accounts — it hands the account name to Claude Code as the initial prompt and starts the session under the anchor, with no error. claude-<name> is untouched and works, and so does CodeV's own account picker, which never goes through the dispatcher. Filed as #161 with the mechanism and the measurements; the README now points at claude-<name> for cmux and the "not yet supported" note mentions the missing warning.

Scope

Documentation only — no code, no tests, no version bump.

🤖 Generated with Claude Code


Summary by cubic

Documents shared auto-memory, which shipped in #160 without README coverage, and corrects two inaccurate claims about account management.

  • Adds the codev account share-memory <name> on|off CLI entry, a shareable auto-memory row, and a Shared auto-memory section covering what is shared, what is not, and confirming both generated launcher forms carry the redirect.
  • Corrects the "refreshes accounts.sh on every launch" claim: the refresh is packaged-only, and an older installed app can silently downgrade a newer generated file.
  • Corrects cmux behavior: cmux replaces the claude dispatcher, so claude <name> doesn't switch accounts; cmux users should use claude-<name>, while CodeV's account picker still works in cmux.
  • Adds design-doc rationale for the sharing table: scanned directories need symlinks, path-based items need no sharing, plugins carry per-account state, and auto-memory is a launch-time --settings redirect.

Written for commit 7974fc2. Summary will update on new commits.

Summary by CodeRabbit

  • Documentation
    • Clarified supported launcher formats and redirect behavior, including cmux’s required claude-<name> form.
    • Documented the share-memory command, account-to-folder mapping, and rename/remove behavior.
    • Added guidance on packaged-only account script refreshes and shared auto-memory limitations.
    • Expanded Projects tab guidance for account overrides.
    • Explained how skills, commands, plugins, hooks, scripts, and settings are shared or kept account-specific.

#160 shipped without touching the README, so the Multi-Account
section still describes sharing as symlink-or-copy only.

Adds `share-memory` to the CLI table, an auto-memory row to the
shareable-items table, and a short section of its own: what is shared
(memory), what is not (transcripts), and which launch paths carry the
redirect. The point the table cannot make on its own is that this one
is NOT a symlink — it is a per-launch `--settings` redirect — so it
needed prose beside the Link/Copy wording.

Two corrections while in there, both found the hard way:

"CodeV refreshes accounts.sh on every launch" is packaged-only; the
sync returns early unless `app.isPackaged`. The consequence is worth
stating: regenerate from a newer checkout, then open an older
installed CodeV, and the older template silently replaces the file.

And cmux's shell integration installs its own `claude` wrapper after
~/.zshrc, replacing the dispatcher — so `claude <name>` there sends
the account name as a prompt and starts under the anchor, silently.
`claude-<name>` still works and is now the documented form for cmux
(#161).

The new cmux warning and the UI table read as contradicting each
other: one says the dispatcher does not switch accounts in cmux, the
other says the account override applies to cmux. Both are true for
different launch paths, so the table now says which and why.

Both reviewers caught the same gap, and it lands exactly where it
hurts: the previous round told cmux users to switch to
`claude-<name>`, while the shared-memory table listed only
`claude <name>` as carrying the redirect. Verified from the
generator rather than assumed — `claude-<name>` and the dispatcher
branch both come from launchCmd(account, true), and generating
accounts.sh from a sharing registry emits the identical
`--settings "$(_codev_memory_settings)"` in both.

Also fixes a sentence I broke in the previous commit: a trailing
"breaks" left dangling after the #161 link.

Section 5's table says WHAT each item does; it never said why, so
every new item was a fresh argument. It follows from how Claude Code
locates the thing: it scans a fixed directory (only a symlink is
zero-drift), it runs a path you wrote (no sharing mechanism needed at
all — one script, two registrations), or it is a directory plus
per-account state (plugins: linking the payload saves ~780KB and
nothing else, linking the registries makes one account's install
change the other's).

Two things that look like conventions and are not: hooks/ and
scripts/ are NOT Claude Code directories — measured, neither exists
in a second account it has managed for months — and settings.json is
a mixed file, which is the whole reason four keys are copied out of
it rather than the file being linked.

Grammatically fine ("the form [that] cmux forces you onto shares
memory"), but a reviewer parsed "shares" as a noun, which is
evidence enough that a reader would too. Split into two sentences.

Make §5 use one sharing contract. The prose keeps plugin registries and enabledPlugins per account, and rejects whole-file settings.json links. However, the table still permits symlinking the whole plugins/ directory and settings.json. Following those rows shares installed_plugins.json, enabledPlugins, permissions, and hooks between accounts. The prose also places identity in settings.json, while the table and README place identity and trust in .claude.json. Split the skills/ and commands/ row from plugins/, mark plugins/ and whole-file settings.json as non-shareable, retain only the four per-key settings copies, and assign identity and trust consistently to .claude.json.
