Pi installed with its own installer (curl pi.dev/install.sh, a launcher script at ~/.pi/agent/bin/pi) had no proven package manager, so the update toast said "Pi can be updated from provider settings." with no button. The same happened for any provider installed in a way the resolver did not recognize.

  • When no package manager is proven, the resolver now falls back to the provider's own updater: pi update --self, claude update, codex update, opencode upgrade (Grok already used grok update). Each of these detects its own installer, and the runner's post-update version check still reports an updater that exits 0 without updating.
  • Yarn global and Volta installs are detected and updated with yarn global add / volta install (and support version pinning).
  • A Homebrew keg uses its own <prefix>/bin/brew when brew is not on the server's PATH (GUI-launched desktop).
  • Still manual: mise installs and wrapper scripts that run mise x (version pinned in mise config), and node_modules paths we cannot attribute to the provider's package (another package or a project dependency). Cursor and Antigravity ship with T3 Code and are unchanged.

Verification

  • Real installs, resolved with the new code: managed Pi 1.0.1 at ~/.pi/agent/bin/pi resolves to pi update --self (old code: manual); npm-prefix Pi still resolves to npm install -g --prefix …. Running pi update --self non-interactively updated 1.0.1 to 1.0.2 (npm install) and exits 0 on an up-to-date managed install.
  • One-click update through the app updated a managed Pi from 1.0.1 to 1.0.2 (binary reports 1.0.2 afterwards).
  • Server provider tests (1312), typecheck, and lint pass.

Evidence (isolated dev server, Pi pointed at a pi.dev managed 1.0.1 install)

Before: managed Pi had no update action.

before: toast says Pi can be updated from provider settings, no update button

After: the toast offers Update, and the Pi card offers Update now with pi update --self.

after: update toast with Update button, Pi v1.0.1 listed with an update icon

after: Pi card popover with Update now and the pi update --self command

Clicking Update now runs the managed updater and Pi refreshes to 1.0.2:

after update: Pi v1.0.2 with no update pending

Fall back to the provider's own updater (pi update --self, claude update,
codex update, opencode upgrade) when no package manager is proven, detect
Yarn and Volta globals, and use the keg's brew when Homebrew is not on PATH.

🟠 High provider/providerMaintenance.ts:434

For an unrecognized Codex executable, fallback returns native and exposes a one-click update with env: { CODEX_HOME: sharedHomePath }. makeCodexMaintenanceResolver therefore updates the shared CODEX_HOME installation instead of the configured binary, leaving that binary outdated while potentially modifying an unrelated installation. Keep this fallback manual for Codex unless the executable proves a standalone install or its matching home can be derived.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR substantially broadens one-click provider updates across native, Yarn, Volta, mise, and Homebrew installation paths, changing production update behavior and introducing package-management side effects. An unresolved high-severity Codex fallback risk further warrants human review of which installation is actually targeted.

📝 Walkthrough

Walkthrough

Provider maintenance resolution now supports native updater fallback for some unproven installs and adds Yarn and Volta update actions. It also changes mise and Homebrew ownership checks, configures Pi’s native updater, and updates provider maintenance guidance.

Changes

Provider maintenance

Layer / File(s) Summary
Install ownership and updater selection
apps/server/src/provider/providerMaintenance.ts, apps/server/src/provider/providerMaintenance.test.ts
Native updater selection can omit an ownership predicate. Unproven paths outside node_modules can use the provider’s native updater; mise-managed installs remain manual-only.
Package-manager actions and ownership checks
apps/server/src/provider/providerMaintenance.ts, apps/server/src/provider/providerMaintenance.test.ts
The resolver adds Yarn-global and Volta update actions. It detects mise wrappers and Volta installs, and can invoke Homebrew beside a keg when brew is not on PATH.
Provider configuration and update guidance
apps/server/src/provider/Drivers/PiDriver.ts, docs/internals/providers.md, docs/user/install.md
Pi’s native update action runs update --self. The documentation describes installer ownership, native updater fallback, mise handling, and supported update paths.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Bug fix

Suggested reviewers: juliusmarminge

Merge Risk: 🔵 Low · up to f9d03

An oversized mise wrapper can incorrectly offer a one-click update. This is a narrow case; keep uninspectable wrappers manual-only before merging.

Security Architecture Review

Security architecture risk: 🔵 Low · up to f9d03

Update execution retains instance checks, coordination, and post-update verification. However, an oversized version-manager launcher can now be offered an update despite the manual-only policy for pinned installations. Ownership detection and recovery behavior inside the external updaters remain unverified.

Retained concerns

  • Low · architecture · inferred: A configured Pi launcher outside recognised installer paths that invokes mise but exceeds 16 KiB can now receive update --self: wrapper inspection returns false and the resolver selects native fallback. Previously, Pi had no native updater for this unproven installation. This weakens the manual-only boundary for pinned installations; whether the external updater actually changes the pinned installation remains unverified.
Security review details

Security Blast Radius

  • inferred — Update effects can reach provider installations and global package-manager locations writable by the server process, rather than being confined to a conversation or project. The inspected spawn path shows no additional privilege grant, and the request cannot directly supply the update command.

Security Findings and Attack Paths

  • inferred — The retained concern requires a configured oversized mise launcher outside recognised installer paths and an update invocation. Its newly reachable outcome is an update action despite the pinned-install exclusion. Attacker authority over that configuration and an actual unintended installation change were not established, so this is not a verified remote execution or privilege-escalation path.

Trust Boundaries and Controls

  • observed — Commands are generated from provider definitions and installation capabilities rather than request-supplied command text. Live instance/driver matching, fresh ownership selection, and target-version compatibility checks constrain the transition from an update request to process execution. Transport authorization is not established by these controls.

Resilience and Maintainability Implications

  • observed — The command has a five-minute timeout and scoped child termination. Successful exit triggers fresh installation resolution and provider verification; missing installations or still-outdated versions can produce an unchanged result. These checks detect some ineffective updates but cannot prevent earlier writes to the wrong installation or guarantee recovery from interruption.

Hardening Proposals

  • proposed — Preserve bounded launcher inspection, but distinguish an uninspected launcher from a confirmed non-mise executable. Keep ambiguous launchers manual-only unless another ownership proof establishes that automatic updates respect the pinned installation.

Keep oversized mise wrappers manual-only.

For an oversized mise launcher at an otherwise unowned Pi command path, isMiseWrapperScript returns false. The resolver can then expose Pi’s update --self action using the resolved wrapper path, contrary to the manual-only rule for mise installs. Keep wrapper inspection failures from turning a mise-managed install into a native-update fallback.
