Nothing writes to `/root`, `/etc`, `/opt` or -`/usr/lib/node_modules`. The `/etc` paths above are read only, and -`NPM_CONFIG_PREFIX` keeps every npm global write in `/data/agents`. No CLI -depends on a keyring on Linux. - -## Further findings for the container - -1. **Every agent's subprocesses inherit `NPM_CONFIG_PREFIX=/data/agents//`.** - The wrapper exports it for the agent process, so a `npm install -g`, - `npx` or `npm prefix -g` that the agent's own shell tool runs targets the - agent's prefix, not `/data/agents/custom`. The installed command lands in - `/data/agents///bin`, which is not on `PATH`. Reinstalling the - agent, which deletes the prefix, removes it. This follows from process - environment inheritance; it was not run. Terminal panes are unaffected: - they get Tcode's own environment, where the prefix is `/data/agents/custom`. -2. **A newer npm on `PATH` would break three self-updaters.** Claude Code, - OpenCode and Grok rely on `postinstall`, and their updaters do not pass - `--allow-scripts`. npm 11.19.1 in the image runs those scripts with a - notice. npm 12 skips them by default. The likeliest way npm 12 reaches - `PATH` is a user's `npm install -g npm@latest`, which lands in - `/data/agents/custom/bin`, ahead of the image's npm. -3. **Tcode's Cursor home override does not move the login.** Tcode maps a - provider home to `CURSOR_CONFIG_DIR` (`crates/agent/src/lib.rs:813`), but - Cursor reads `auth.json` from `$XDG_CONFIG_HOME/cursor` or - `~/.config/cursor`, and project data from `CURSOR_DATA_DIR` or `~/.cursor`. - Two Cursor profiles with different homes would share one login. This is not - specific to the container. -4. Tcode's own provider-update detection probably reports these installs as - `Unknown`. It canonicalizes the command on `PATH`, and the sh wrapper in - `/data/agents/bin` is not a symlink. The resolver recognizes only Windows - `.cmd` shims as wrappers (`crates/services/src/version_check/provider_updates/installation.rs` - around lines 1290-1330), and it binds npm updates to `npm root --global`, - which here is `/data/agents/custom`. If so, Tcode offers no in-app updates - for the five npm CLIs. Unverified; settled by checking what Settings → - Providers shows in a running container. -5. `docker compose exec` without `--user tcode` runs as root with - `HOME=/data/home`. Running a CLI that way leaves root-owned files in the - shared home (`.claude.json`, `.codex/`), which the `PUID` user then cannot - rewrite. The entrypoint only fixes ownership at the next start, and only - when `/data` itself has the wrong owner. `docs/docker.md` already says to - use `--user tcode`. - -## Recommendations - -Each item is tied to the finding it addresses. What the container does now: - -- Item 1 is not applied. An exported `NPM_CONFIG_ALLOW_SCRIPTS` reaches every - process an agent starts, so under the image's npm 11 it would skip the - install scripts of a project's own dependencies whenever an agent runs - `npm install`. `docs/docker.md` says to keep the image's npm instead. - (npm 11.19.1 and 12.2.1 both read `allow-scripts` from the environment, - checked with `NPM_CONFIG_ALLOW_SCRIPTS=x npm config get allow-scripts`.) -- Item 2 is superseded: npm CLIs install into the image's own global prefix, - `/data/agents//npm`, which is on `PATH`, with no wrapper. An agent's - global installs land there, run and persist, and the CLIs resolve as npm - global installs, so Tcode's provider update recognises them (finding 4). - An npm CLI left out of `TCODE_AGENTS` is uninstalled to keep it off `PATH`. -- Item 3: docs only, as recommended. -- Item 4: the Grok command links to `~/.grok/bin/grok` once it exists. The - package's `postinstall` installs the build there (observed: `~/.grok/bin/grok - -> grok-1.0.70`), so both update paths move the binary that runs. -- Items 5 and 6: applied to `docs/docker.md`, with Tcode's provider update - as the way to update Codex, pi and OpenCode. -- Item 7: `CURSOR_DATA_DIR` joins `CURSOR_CONFIG_DIR`; the login stays shared, - because moving `XDG_CONFIG_HOME` or `HOME` would also move the configuration - of every tool the agent runs. The `LaunchEnv` documentation says so. - -1. **Pin the install-script policy for self-updates** (finding 2). In - `install-agents.mjs`, add `NPM_CONFIG_ALLOW_SCRIPTS=''` to the - wrapper, next to `NPM_CONFIG_PREFIX`. Then the CLIs' own `npm install -g` - keeps running `postinstall` under any npm. npm reads `allow-scripts` like - any other config key (`npm@11.19.1:docs/content/using-npm/config.md`: - "persist the setting with `npm config set allow-scripts=…`"). That npm - accepts it from the environment is unverified; settled by - `NPM_CONFIG_ALLOW_SCRIPTS=x npm config get allow-scripts`. -2. **Document, or contain, the inherited prefix** (finding 1). The minimal - step is a sentence in `docs/docker.md` → *Choose agents*: global npm - installs made by an agent's own tools go into that agent's prefix. To - contain it, the wrapper can keep `NPM_CONFIG_PREFIX` and also prepend - `/bin` to `PATH`, so such installs at least run. Moving them to - `/data/agents/custom` would need each updater to target a prefix some - other way. pi already does this (`--prefix` inferred from its own path); - the other four would need a different launch mechanism. -3. **Decide about the temp tree** (Claude scratchpad and pasted images; OpenCode - tmp). If those should survive restarts, set `CLAUDE_CODE_TMPDIR` - (Claude-only), or `TMPDIR` (all CLIs), to a directory on the volume such as - `/data/tmp`, in the Dockerfile `ENV` and created by `entrypoint.sh`. - Otherwise state in `docs/docker.md` → *Data and projects* that `/tmp` is - not persisted and that Claude's scratchpad and pasted-image copies live - there. The docs-only option is recommended: neither CLI treats these as - durable state. -4. **Grok update target** (Grok item 6). Until the npm-versus-download - question is settled, either set `GROK_DISABLE_AUTOUPDATER=1` in the Grok - wrapper and rely on `grok update` run in a pane, or have the wrapper exec - `$GROK_HOME/bin/grok` when it exists. That symlink is the one both the npm - `postinstall` and the native updater maintain. The second option is - preferred if the experiment shows the background updater downloads into - `~/.grok/bin`. -5. **`docs/docker.md` credential table** (verification above). Keep the rows - and add the missing state: - - Claude: `.config/anthropic` for a Console sign-in. - - Codex: `.codex/.credentials.json` for MCP OAuth. - - OpenCode: `.local/share/opencode/mcp-auth.json`. - - Cursor: say that `.config/cursor/auth.json` is the login and `.cursor` - holds config and chats. - - Grok: `.grok/mcp_credentials.json`. - - One footnote should say that no CLI uses a keyring on Linux, so nothing - depends on D-Bus. -6. **`docs/docker.md` → *Choose agents* and *Upgrade*** (summary table, self-update - column). Replace "updates itself the way that CLI does outside a - container" with the actual split. Claude Code and Cursor update in the - background. Grok has a background updater, target unverified. Codex, pi and - OpenCode update only when you run their update command (`codex` TUI - prompt, `pi update`, `opencode upgrade`) in a terminal pane. In *Upgrade*, - add `~/.local/bin/cursor` to the Cursor reinstall list. -7. **Cursor home override** (finding 3; outside `crates/headless`). When - Tcode applies a Cursor home, it should set `XDG_CONFIG_HOME` and - `CURSOR_DATA_DIR` as well as `CURSOR_CONFIG_DIR`, or document that the - override does not isolate the login. - -## Not confirmed - -- Whether Claude Code's background updater runs in `-p`/SDK sessions (Claude item 6). -- Grok's update path for npm installs (Grok item 6), and Grok's temp-file - use. The source is not public; only binary strings were read. -- What OpenCode keeps in `/tmp/opencode`. -- Tcode's own update detection for wrapper scripts (finding 4). -- No CLI was run in a container.
