feat(accounts): share the anchor's auto-memory, per project by grimmerk · Pull Request #160 · grimmerk/codev

grimmerk · 2026-09-18T12:38:18Z

Auto-memory is stored per project, under each account's own config dir, so two accounts on one machine keep two separate memories for the same repository. This adds an opt-in, per-account switch that points a non-anchor account at the anchor's memory for whichever repository a session starts in — one repository, one memory.

Off by default. The anchor is never offered it: its memory is the one the others share.

Mechanism

autoMemoryDirectory relocates auto-memory and --settings is a settings scope that accepts a JSON string, so a launcher can redirect one launch without touching either account's settings.json and without writing anything into the repository. The directory has to be computed per launch, because it depends on the repository the session starts in.

The slug rule, measured against Claude Code 2.1.276:

the key is the git common directory's parent, so a repository, its subdirectories and all of its linked worktrees resolve to one memory. Verified against a real linked worktree: it reports the main repository's .git, and projects/ holds only the main repository's slug;
outside a git repository the key is the working directory itself;
the slug is that absolute path with every non-alphanumeric byte replaced by -, case preserved.

Three launch paths, not one

A session under a non-anchor account can start in three ways. Covering only the shell dispatcher would have left the app's own buttons writing to the old place, which is most of how CodeV is used — so all three carry it:

Path	How
`claude <name> …` and `claude-<name>` (the generated `accounts.sh`)	`_codev_memory_settings` computes the payload from `$PWD` at launch; inline JSON
CodeV resume (`buildResumeCommand`)	`--settings <file>` under `~/.config/codev/memory-settings/`
CodeV new session under a picked account (`launchNewClaudeSession`)	the same file

claude-whoami is deliberately untouched — auth status is not a session.

Why CodeV's paths use a file rather than the same inline JSON: they embed the command in an AppleScript string, and two of the four terminals interpolate it unescaped — Ghostty's initial input:"…" and cmux's --command "…". A JSON payload's double quotes would end the string and the launch would fail. (iTerm2 and Terminal.app do escape; the repo already learned this once, which is why the CLAUDE_CONFIG_DIR prefix is single-quoted.) A path under ~/.config/codev contains no quotes at all. The shell dispatcher has no AppleScript layer, so inline JSON is safe there.

One rule, two implementations — pinned together

The rule lives once, in src/cli/memory-dir.ts. The shell function in accounts.sh is generated from that same module, and memory-dir.test.ts runs it under zsh and asserts it agrees with the TypeScript for a repository, a subdirectory, a linked worktree and a plain directory. Without that the two would drift, which is the failure mode this repo has hit before.

What is NOT shared

Session transcripts. Claude Code still writes them to the launching account's own projects/<slug>/ — confirmed by probe: the slug directory is created for the transcript, with no memory/ inside it. That is what keeps CodeV's per-account session attribution working, and it is why this is memory sharing rather than session sharing.

Known gap, stated in the UI rather than hidden: a session started outside both launchers — a bare CLAUDE_CONFIG_DIR=… claude, or the VS Code extension — uses that account's own memory for that session. Nothing breaks; it just does not see the shared copy.

Verification

Each link of the chain was measured, not assumed:

--settings inline JSON does relocate auto-memory. Probe from a non-repository directory with a scratch target: the memory file and its MEMORY.md landed in the target. A slug directory was created under the account — containing only the session transcript, no memory/ — which is the transcript behaviour above.
The slug rule matches Claude Code, checked against directories already on disk, including the worktree case.
End to end, through the real dispatcher and a real non-anchor account: an accounts.sh generated with the anchor pointed at a scratch path, sourced in a subshell, claude <name> -p … run from a real repository. The memory landed at <scratch>/projects/<repo-slug>/memory/, and no memory directory appeared under the launching account for that repository. Nothing real was written.
Mutation-verified: making the shell slug rule diverge from the TypeScript one, and making the shell ignore the git common directory, each turn the agreement test red — so the test is attached to the behaviour.
208 tests (13 new), tsc clean.

Notes for review

RegistryAccount / CodevAccount / the renderer's row type each gained the flag; that three-way duplication of one registry record predates this change.
feat: launch Claude session as git worktree (⌘+Shift+Enter) #119 (worktree launch) touches some of the same files. It composes cleanly: a session launched in a worktree resolves to the parent repository's memory, which is the intended behaviour here.
The relayed request described only the shell launcher and inline JSON everywhere. The two deviations — all three launch paths, and a file for the app's own launches — are explained above; both were needed for the stated goal ("one memory per repo") to actually hold.

🤖 Generated with Claude Code

Review round 1 (18 threads, ~12 distinct after de-duplicating the two bots — all addressed in `35d409d`)

CI was red on the first head and that was mine: both new tests shell out to zsh, which Ubuntu runners do not have. The workflow installs it now rather than the tests dropping to bash, because zsh is the shell that actually sources the generated accounts.sh.

The finding worth reading: both reviewers asked for git discovery variables to be cleared, and both spelled it GIT_DIR= git rev-parse …. Taken literally that breaks the lookup — an empty GIT_DIR is not an unset one, git answers fatal: not a git repository: '', and every subdirectory and worktree silently falls through to the working-directory branch. I applied it as written and the shell-versus-TypeScript agreement test went red on the subdirectory case, which is exactly what that test is for. It is env -u on the shell side and a deleted key on the TypeScript side, with a test that poisons GIT_DIR and asserts the repository still wins.

Also fixed: the settings path is single-quoted (a home directory with a space truncated the launch); the settings file is written temp-then-renamed; the registry flag is read as strictly true in both readers, so a hand-written "false" cannot switch an account into the anchor's memory; the helper is emitted whenever any account carries the flag, including a registry with no anchor marked, since that is exactly when a launcher would call it; getAnchorDir resolves; the shell slug translates newlines before sed; the checkbox disables while the IPC is in flight; the help text is no longer a <div> inside a <span>; and share-memory reports which half of its arguments was wrong.

One declined, with the reasoning in the code. The slug collides (/tmp/a-b and /tmp/a/b both become -tmp-a-b). That is Claude Code's own rule, it already applies to a single account today, and the job of this module is to name the directory Claude Code will actually read — a collision-free key would name one it never opens.

Review round 2 (3 threads — `9ed9c40`)

The UTF-16 divergence is closed, not documented. Round 1 declined it on the reasoning that the TypeScript side matches Claude Code because Claude Code is JavaScript — an inference. Measuring it changed the answer: a real session run in a directory whose path contains 😀 makes Claude Code name its projects/ directory with four dashes for the surrogate pair, confirming it counts UTF-16 code units and that the shell twin was the wrong side. The helper now normalises with perl -CSD -pe 's/([^a-zA-Z0-9])/"-" x (ord($1) > 0xFFFF ? 2 : 1)/ge', which is exact for both planes; perl ships with macOS, the only platform this app runs on, and runs per launch rather than when a shell sources accounts.sh. An astral path joins the newline and BMP cases in the agreement test, and reverting the helper to sed turns it red.

The one prettier/prettier finding in src/cli/account-manager.ts is fixed — that file has no others, so formatting the line leaves it as clean as it was found. The same finding on src/popup.tsx is declined with counts: that file has 787 findings, this PR added 55 lines, 33 of the findings land on them, and all 33 are indentation — the same complaint the surrounding code has, since 15 of the 15 unchanged lines immediately after the block also have one. Formatting only these lines would indent them differently from the code they sit inside and would not make yarn lint cleaner; there is no lint gate in CI either.

Summary by cubic

Previously, each account kept a separate Claude Code auto-memory for the same project. This adds an opt-in per-account switch that redirects non-anchor sessions to the anchor's project memory, while keeping session transcripts under the launching account and leaving the switch off by default.

Resolves memory per launch from the Git common directory, so repositories, subdirectories, and linked worktrees share one memory; non-repository paths use the working directory.
Applies to shell launches, CodeV resume, and new-session launches; CodeV uses a safely quoted settings file for terminal integrations.
Configure sharing in Settings → Accounts or with codev account share-memory <name> on|off; the anchor cannot enable it.
Bare CLAUDE_CONFIG_DIR=… claude launches and the VS Code extension continue using the account's own memory.
Keeps the TypeScript and generated shell rules aligned with zsh tests, including inherited Git environment variables and concurrent settings-file writes.

^{Written for commit 35d409d. Summary will update on new commits.}

Summary by CodeRabbit

New Features
- Added per-account auto-memory sharing with the anchor account, configurable per project and disabled by default.
- Added a Settings checkbox and the codev account share-memory <name> on|off command.
- Shared memory applies across repositories, subdirectories, and linked worktrees while keeping session transcripts separate.
- Added support across account launchers, resume flows, and new-session launches.
- Sessions launched outside supported account flows continue using their own account memory.
Documentation
- Documented configuration behavior, project scope, launch paths, and known limitations.

Auto-memory is stored per project under each account's own config dir, so two accounts on one machine kept two memories for the same repository. `autoMemoryDirectory` relocates it and `--settings` is a settings scope, so a launcher can point a non-anchor account at the anchor's copy without touching either settings.json and without writing into the repository. The directory is computed per launch — it depends on the repository the session starts in: the git common dir's parent, so a repo, its subdirectories and all its linked worktrees resolve to one memory; outside a repo, the directory itself. All three launch paths carry it, not just the shell one. Covering only the dispatcher would have left CodeV's own resume and new-session buttons writing to the old place, which is most of how the app is used. CodeV's two paths pass a settings FILE rather than inline JSON: they embed the command in an AppleScript string and Ghostty's `initial input` and cmux's `--command` interpolate it unescaped, so a JSON payload's quotes would break those launches. The dispatcher has no AppleScript layer and uses inline JSON. The rule lives once (memory-dir.ts); the shell function is generated from the same module and a test runs it under zsh to assert the two agree for a repo, a subdirectory, a worktree and a plain directory. Off by default, per account, and never offered on the anchor. Session transcripts are NOT shared — Claude Code still writes them under the launching account, which keeps per-account session attribution working.

Review round 1 (CodeRabbit + cubic, 18 threads, ~12 distinct). CI was red and that was mine: both new tests shell out to zsh, which the Ubuntu runner does not have. zsh is what sources accounts.sh in real use, so the workflow installs it rather than the tests dropping to bash. Git discovery variables are now unset for both implementations, so an inherited GIT_DIR cannot key the memory to another repository. Both reviewers suggested the `VAR=` form; taken literally it BREAKS the lookup — an empty GIT_DIR makes git fail outright and sends every lookup down the $PWD fallback. `env -u` on the shell side, a deleted key on the TypeScript side, and a test that pins it. Also: the settings path is single-quoted, so a home directory with a space no longer truncates the launch; the settings file is written temp-then-renamed, so two launches for one repository cannot read a truncated one; the registry flag is read as strictly `true`, so a hand-written "false" cannot switch an account into the anchor's memory; the generated helper is emitted whenever any account carries the flag, including a registry with no anchor marked, since that is exactly when a launcher would call it; `getAnchorDir` resolves, so a relative registry dir cannot put memory under the working directory; the shell slug translates newlines before sed; the checkbox disables while the IPC is in flight; the help text is a span, not a div inside one; and `share-memory` says which half of its arguments was wrong. Declined, with the reasons in the code: the slug collides (`/tmp/a-b` vs `/tmp/a/b`) and counts UTF-16 code units. Both are Claude Code's own rule, and the point of this module is to name the directory Claude Code will actually use. The UTF-16 half does leave a real divergence outside the Basic Multilingual Plane, measured and documented. 208 tests (3 new: newline and non-ASCII paths, inherited git variables, a registry with no anchor).

Review round 2 (CodeRabbit, 3 threads). The astral-plane divergence is closed rather than documented. Measured it first: a real session run in a directory whose path contains an emoji makes Claude Code name the projects/ directory with FOUR dashes for the surrogate pair, so it counts UTF-16 code units and the TypeScript side was the correct one. The shell twin normalised with sed, which counts characters and emitted three. The helper now normalises with perl, which can count code units; perl ships with macOS, the only platform this app runs on, and the call is per launch, not per shell startup. The agreement test gains an astral path beside the newline and BMP ones. Also: the one prettier violation in account-manager.ts, in a file that has no others.
