feat(web,mobile): install and update plugins from npm in Settings by saphid · Pull Request #16057 · pingdotgg/t3code

saphid · 2026-10-05T12:08:54Z

Stacked on #16056 (and #15010). Review only the top 2 commits: 1d7af3b.

Rebased 2026-10-10 onto #15010's current head (1fe8efd69a, on main 57b3780). The npm settings test's session mock provides main's useEnvironmentScope, which settings rows now read. Apart from context lines, the patch is unchanged by this rebase, so the earlier review still applies. A bot review found a downloaded update of the installed version was hidden in the list; "fix(client-runtime): show a downloaded same-version plugin update in the list" shows it for review (GPT-6.1 Sol (high): SHIP). Captures below were taken at the revisions they name. At this head (1d7af3bd3a) these pass: focused tests (11 files, 137 tests), typecheck (@t3tools/mobile, @t3tools/web, @t3tools/client-runtime, @t3tools/contracts), lint and fmt on the changed files, knip, lint:mobile.

iOS: this PR's mobile surfaces were also captured on an iPhone 17 Pro simulator (iOS 26.5), at the top-of-stack head 5ec8b17, which contains this PR: light-npm-provenance. These are after-only captures; the before/after comparison below is on Android.

Problem

The server can install plugins from npm (the npm install PR below this one), but no client offers it. A user who wants a published plugin has to send raw plugins.npm.* requests from an administrative connection, and has no screen that shows the package, its registry checksum or the scripts policy before they approve it. Updating an npm plugin is the same: there is no way to download, review and apply a new version from the app.

This PR adds installing and updating plugins from npm to the Plugins page on web and desktop. Mobile shows where a plugin came from, read-only.

Why this qualifies

This is the proposal route in CONTRIBUTING, and no maintainer has agreed to it yet. It needs the plugin-system approval on #6714 / #6837, like the plugin PRs below it.

It stacks on the plugin settings forms PR, and is the first client of the npm install PR's RPCs; we recommend reviewing the two together. It adds no server code, no RPC and no scope. If the answer is no, we close this with the plugin PRs around it. Previous PR in this stack: feat(web,mobile): fill in plugin settings from Settings (#16056).

Fix

Shared client state (packages/client-runtime):

state/pluginNpm: the npm list query and the four npm commands (add, stageUpdate, applyUpdate, discardUpdate), one step per environment at a time. Every request checks the pluginNpm capability on the session it would use, so an older server never receives one.
state/pluginNpmPresentation: the request gate for the install and update forms (decodes the package name and version with the contract schemas, so ranges are refused before sending; an empty version means latest; an empty registry is left to the server's default), the npm list state, and where each installation came from. After a step, the step's reply is trusted only until a list read that started after the step; after a failed step the screen says "Checking what is installed…" until that read, so it never claims a version after a rollback. settlePluginNpmStep (in state/pluginNpm) records the list the client holds when the step settles and reads it again in the same call; that refresh cancels a read already running, so a list that arrived while the step ran, or a read that started before it ended, cannot take the place of the reply. The list is read again after each npm step and when installations or their files change, never on a timer.
The existing action gate also binds an applied update to the downloaded digest the user acknowledged, and refuses approval while an npm-capable server has not yet said where the files came from.

Web and desktop (Settings > Plugins): Install from npm next to Add plugin, only on servers with pluginNpm. The dialog takes a package, a version or tag, and an optional registry, and explains an invalid request inline. Download and review opens the existing review, which now also shows the package, its sha512 integrity and what it means, and the scripts policy. Discard removes a download nobody approved. Rows of npm plugins show npm · name@version, and "Update X ready to review" when one is downloaded. In an npm plugin's details, Updates downloads a version next to the installed one, shows its version, integrity, digest and capabilities (new ones highlighted, removed ones listed), and applies it only after the user ticks trust for that exact download. The Remove confirmation says the plugin's saved settings and storage are deleted, and what happens to its files: an added directory stays, a downloaded copy is deleted, and while the origin is not yet known it says both.

Mobile (read-only): a plugin's row shows npm · name@version, and its screen shows Package and Integrity (with what the checksum means). Installing, updating and discarding are not on mobile: the mobile app always pairs with standard scopes (unchanged from main), so it never has the access:write these steps need, and its Plugins screens already say plugins are managed from an administrative web or desktop connection.

Access: every npm step needs access:write, as on the server (plugins.npm.list is orchestration:read, the four mutations are access:write). A standard pairing sees npm provenance but the entry and every action are disabled, and each submit path refuses at dispatch, not only through disabled controls.

Docs: docs/user/plugins.md "Installing from npm" now describes the app flow. The raw-request section is replaced by a short "Publishing to npm" note for plugin authors, and Managing says removing an npm plugin deletes the server's copy.

Size: 15 files, +2215 / −70. About 1.1k of the added lines are tests (the fake server these tests use comes from the plugin management PR).

Evidence

Environment: macOS arm64; this PR on top of the plugin settings forms PR.

How to exercise it: use an isolated vp run dev and a local registry that serves npm pack --ignore-scripts tarballs of a fixture plugin at 1.0.0 and 1.1.0 with their sha512 integrity. Install from npm with that registry, approve, then download 1.1.0 under Updates and apply it. Then pair a second client with a standard link.

Captures (isolated dev server on fresh state, web in Chromium, the built desktop app, and one vp run dev --share remote browser; the environment label is a neutral "Proof server"; the registry is a local test registry):

	Before	After
Web, light
Web, dark
Desktop, light
Desktop, dark

Install, review, approve (web video, desktop video): a range is refused inline and nothing is sent; the review shows the package and registry, the sha512 integrity and what it does and does not prove, the digest, and the scripts policy; Approve stays disabled until trust is ticked; the row then reads "npm · name@1.0.0".

Range refused	Review (untrusted)	Review (dark)	Enabled

Update (video): downloading 1.1.0 shows its integrity, digest and capabilities with the new one highlighted ("New: tools"); the row says "Update 1.1.0 ready to review"; Apply needs trust for that download; then "Updated to 1.1.0". Discard update returns to the empty form.

Staged	Row	Updated	Failed apply → "Checking what is installed…"

Failed apply (video): with the staged files removed on disk, Apply shows the server's error, "Checking what is installed…", then the version the server reports.

Provenance not loaded	Postinstall refused	Standard pairing	Server without npm

While the npm list is held or fails (intercepted in the test browser), the review says "Checking where it came from…", then "Not known…" with Retry, and approval waits. After Retry the package and integrity appear.
A package with a postinstall script is refused by the server, inline.
Removing an npm plugin drops its row live in a second admin tab.
A standard pairing sees View only with Install from npm disabled; its sessions sent 0 npm mutation requests (browser wire counters, local and remote).
A server without npm support, paired as a second environment, has no Install from npm, and the client sent it no plugins.npm.list. (That pairing was standard; on an npm-capable server a standard pairing still shows the entry, disabled, so the absence comes from the capability.)

Remote (vp run dev --share, its own pairing link, a fresh browser profile; video): install 1.0.0 → approve → download 1.1.0 → apply worked over HTTPS; a fresh standard pairing was view only. Relay and T3 Connect were not exercised.

The captures above were taken at an earlier revision of this PR that differs from this head outside mobile only in the Remove confirmation's wording and in comments and tests, so every web and desktop state above renders the same here. The Remove confirmation and the Android screens below were captured at this head.

Remove (this head, web and built desktop, light and dark): both kinds of plugin say their saved settings and storage are deleted.

	Added directory	npm download
Web, light
Web, dark
Desktop, light
Desktop, dark

Directory: "T3 Code stops the plugin, forgets your approval, and deletes its saved settings and storage. Its directory stays on Proof server's machine."
npm: "T3 Code stops the plugin, forgets your approval, and deletes its saved settings and storage. It also deletes the copy of t3-proof-npm it downloaded to Proof server's machine."

Android (this head, an emulator with a standard pairing; the plugins were installed from an administrative web session): read-only provenance, with no Install from npm, update, discard or remove control.

	Before (parent)	List	Plugin screen	Bottom of plugin screen
Light
Dark

The row reads "npm · t3-proof-npm@1.0.0 from http://127.0.0.1:"; the plugin screen shows Package and the sha512 Integrity with what it does and does not prove; both end with "Plugins are view-only on mobile. Add, install, approve, enable, update, or remove them from an administrative web or desktop connection."

Checks at this head (065649b7cd), re-run 2026-10-05 (vp test run, CI=true, all exit 0):

client-runtime state/pluginNpm, state/pluginNpmPresentation, state/pluginPresentation, state/plugins: 4 files, 73 tests pass. They cover the install and update request gates (exact versions and tags pass, ranges and bad names are refused, nothing is sent without management or while busy), provenance after successful and failed steps, the list key, the update presentation, and the apply gate (refused without acknowledgement, for a different download, or with nothing staged). Two run the real npm list atom against held list reads: a reply outlives a list that arrived during the step until a read after it, and a read already running when the step settles is cancelled.
web PluginsSettings.npm.test.tsx mounts the Plugins section in jsdom with the real atoms and registry; only the server is fake, holding each request until the test answers it. Clicking and typing like a user, it checks that the exact version typed is downloaded; that the review keeps the install's package and checksum when a list read finished during the download and another was running when it ended; consent then enable for the reviewed digest; that a range sends nothing; that an old server gets no entry and no list read; that Discard removes an unapproved download once; and that a failed update download shows "Checking what is installed…" even when a list arrived during it, then applies only the acknowledged download. With PluginsSettings.test.tsx and PluginSettingsForm.test.tsx: 3 files, 13 tests pass.
Every branch of the Remove confirmation (added directory, npm download, origin not yet known, checking) says the plugin's saved settings and storage are deleted; this test fails on the previous wording (recorded during development). Server src/plugins/PluginSettings.test.ts and src/plugins/PluginNpm.test.ts: 2 files, 38 tests pass, including "keeps values across disable and re-enable, and deletes them on remove". Contracts src/pluginNpm.test.ts: 3 pass; mobile dependency-graph: 3 pass.
vp run --filter typecheck for contracts, client-runtime, web and mobile; vp lint --report-unused-disable-directives and vp fmt --check on the added and modified files (no warnings); vp run knip:check; vp run lint:mobile.
Not part of the re-run (no server, desktop or packaging change): vp run --filter @t3tools/web build, vp run build:desktop and node scripts/release-smoke.ts passed at the top of this stack (the example plugins PR), which contains this change.
Recorded during development, not repeated at this head: on the parent the npm test file and the two new client-runtime suites do not load, and the apply-gate test fails. On this PR's code before the review fix, the two race tests fail: the review shows no package, and the failed download shows the old form instead of "Checking what is installed…".

Surfaces

Entry points: Settings > Plugins on web and desktop (header button, review/details dialog, row label and Remove text); Settings > Server settings > Plugins on mobile shows provenance only (row label, Package and Integrity on the plugin screen). There is no command palette or keybinding entry, as for Add plugin.
Clients: web and desktop install and update (same page). Mobile (iOS and Android) shows npm provenance read-only.
Providers: not applicable. Codex, Claude, Cursor, Grok, OpenCode, Antigravity and Pi are unaffected.
Contracts: no wire change. PluginNpmPackageName and PluginNpmVersionRequest (and its type) are exported again so the forms can check input with the server's own schemas.
Reverse states: install ↔ Discard (before approval) or Remove (after); download update ↔ Discard update; apply has no undo, but a failure before it keeps the installed version, and the screen shows what the server reports afterwards.
Connection modes: the existing npm RPCs over the same session, so local, remote/relay and tunnel behave the same; the registry is fetched by the server, not the client. Access and the capability are decided per environment from that environment's session.
Docs: docs/user/plugins.md install, managing and authoring sections rewritten. No internals doc.

Not verified

Most web, desktop and remote captures above come from an earlier revision of this PR (identical here outside mobile, the Remove wording, comments and tests); the Remove confirmation and Android were captured at this head.
Relay and T3 Connect tunnel were not exercised; the remote pass used --share.
Mobile npm install and update are deferred to a separate authority change (mobile pairs with standard scopes, unchanged from main); no scope is changed here.
iOS was not run (an earlier simulator build stalled in ExpoModulesJSI). No Android video: only read-only states are reachable on mobile.
A download staged from another client shows on this one only after its own npm step, a catalogue change, or reopening the screen: the npm list is a query, and the server checks the staged digest on apply either way.
No update check exists (the npm install PR does not provide one), so "Update ready" appears once a download is staged.
The client hides the registry in labels when it is npm's own (https://registry.npmjs.org); that string is a display constant, the server keeps the actual default.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR introduces a full plugin platform with trusted server-side code execution, npm installation and updates, new persistent data, authorization surfaces, MCP/actions/views, and substantial web, desktop, mobile, and orchestration behavior. It also enables multiple capabilities by default and adds static-analysis suppressions, making the aggregate risk and scope unsuitable for automatic approval.

_{Logged so this PR shows when a maintainer was asked to review it.}

Preview becomes the second panel on the side-panel registry that Diff started. Each definition now also carries the panel's title, icon, launcher letter, client support and unavailable copy, so the tabs, the empty launcher and the add menu read one ordered list instead of three hand-kept ones. Labels, letters, order and copy are unchanged. Panel props are inferred from each lazily loaded body, and the caller is a closed union, so another panel's props, unknown ids and widened ids do not compile. ChatView lends the rendered panel a small host (thread, right panel visibility, composer draft target, workspace mutation id and the annotation send) instead of drilling the same props into each body; the annotation send keeps the per-render closure it had before, and PreviewView still drops a pick that settles after a thread switch. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

ChatView built a new PanelHost on every render, so every usePanelHost consumer re-rendered even when no host field changed. Memoize it on its fields and send annotations through onSendRef so the sender stays stable. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

The hook now reads plugin actions for the thread menu, and that module needs React context, which this test's minimal React mock does not provide. These tests cover the built-in menu items, so the plugin actions module is stubbed to return none. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

The slash menu and palette offer plugin actions from the cached orchestration:operate grant, which can be stale after a reconnect. Picking a slash action now reads the live grant first: without it the draft stays untouched and nothing runs; with it the typed command is removed at pick time, as before, and the action runs. runPluginAction reads the live grant too, so a palette entry picked after the grant changed is refused, and it reports whether the plugin ran the action. Nothing writes the draft after the action settles. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

…an open thread The mobile command palette loaded plugin actions only from the open thread's environment, so on a page without a thread it offered none, not even actions that target the environment. Take the open thread's environment, else the first connected one, and pass thread and project only when they exist, as the web palette does. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

A plugin with the `views` capability declares side-panel views (one script, optional stylesheet). The server serves each view's consented bytes per installation generation over three scoped RPCs and revokes them with the generation. Web and desktop list the current session's views in the right panel launcher and mount each in a sandboxed srcdoc frame bridged by one MessagePort; desktop also vetoes view-frame navigations in the main process. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

The view bridge refilled its message bucket from the wall clock, so a clock that stepped back drained it and could close a healthy view for violations. Elapsed time is now never negative. The desktop window also logged the start of a refused plugin view URL, which can carry the view's data in its path or query; it now logs only the protocol and host. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

A view calls its plugin through handlers registered on context.proposed, which only exists with "proposedApi": true. A manifest that asked for views without it could be added and enabled, and then every call from its views failed. The loader now refuses it, as it does for the other proposed capabilities. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

When an environment had plugin views placed outside the side panel, the filtered list was rebuilt on every chat render, so the launchers and both right-panel tab strips got a new array each time. The filtered list is now memoized on the session's views. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

…roup Typing every WebSocket handler against the instrumented group runs past the type checker's instantiation limit once the plugin view RPCs join main's WebSocket methods, and the checker then silently widens the server layer's requirements to `any`. RpcServer finds a handler by its tag alone, so the handlers are typed against the plain group while the server still runs the instrumented one. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

A view asset such as `..board.js` sits inside the plugin directory, but the containment check treated any `..` prefix as leaving it, so the whole installation's views failed to load. Only a whole `..` segment now counts, matching the entry check in the manifest loader. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

A view's files were read before the directory was digested, so a file changed for the read and restored before the digest served bytes that were never approved. Each read file's hash must now match the hash the digest pass took of it, and a file that several views share must read the same bytes every time. A view file that fails to read also runs the digest, so an approved plugin whose view was edited into an invalid file is disabled instead of keeping its stale approval. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

…ed updates Adds `plugins.npm.list/add/stageUpdate/applyUpdate/discardUpdate`, gated on the `pluginNpm` environment capability. Install and update download one exact version, require the registry's sha512 integrity to match, check the whole archive in memory before writing it, refuse install scripts and unbundled dependencies, and hand the unpacked directory to the catalogue, which still requires consent to its digest before anything runs. Applying an update consents to the staged digest and swaps the files in one catalogue step; interrupted swaps are finished or rolled back at startup. Listing needs orchestration:read; installing and updating need access:write. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

The integrity check compares the tarball with the sha512 the same registry publishes. Over plain http a network attacker can replace both, so the check authenticated nothing. Registries must now use https, except a loopback registry for local testing. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

…https rule Only the registry typed into add was checked. Metadata requests followed redirects anywhere, so one plain http hop let a network attacker supply both the integrity and the tarball, and an update of an installation saved from a plain http registry skipped the check entirely. Metadata requests now follow each redirect only to https or a loopback registry, and every metadata lookup refuses a saved registry that is not one. Tarball downloads still follow redirects: their integrity comes from that metadata. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

Three header cases were misread. A GNU header's `ustar ` magic passed the POSIX check, so its access time became a path prefix and files landed under the wrong names. A directory entry's size is space to reserve, not data, so a nonzero one shifted every later header. A pax global header that sets `path` or `size` was skipped, so later entries kept names and sizes their writer did not mean. Only the full POSIX magic and version now read a prefix, directories carry no data, and a global path or size is refused. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

A staged update's summary was built by its own copy of the manifest summarizer, which left out tools, settings, and actions, so an administrator reviewing an update could not see changes to them before applying it. The npm installer now uses the catalogue's summarizer, so the review shows exactly what the catalogue will list once the update is applied. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

The inflate cap allowed 1.5 KiB of header and padding per file, but directories and extended headers are entries of their own, so an archive inside the file, byte, and entry limits could still be refused as too large. The cap now budgets every entry and one tar record of end padding. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

The pax reader dropped each record's last declared byte as its newline without checking it, so a malformed record such as `20 path=package/fooX` renamed the next file instead of being refused. A record whose last byte is not a newline now makes the archive unsafe. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

PluginNpm now reaches the plugin catalogue through its module namespace and builds each PluginCatalogError where the failure happens instead of through a forwarding helper. A failed file step keeps the file system error as the storage error's cause, and every Node builtin import exemption in the npm install modules says why it is needed. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

A pax size waiting for the next file was applied to a GNU long-name record in between, so the reader misread the name and refused a valid archive. Extended headers now always use their declared size. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

A pax path may carry a NUL, which passed the path checks and then failed the staging write after earlier files were already written. Such an archive is now refused before anything is staged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

…nabled again When enabling the plugin again failed after the consent to the new files was saved, applying the update reported a failure although the new version was installed, and a retry found no update to apply. It now returns the applied version and the installation as it is. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Applying an update whose files match the installed ones could lose the package: after a restart between the two moves, recovery read the existing consent as a finished swap and deleted the only copy. Such an update is now discarded before anything moves. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Plugins could only be added, approved, enabled or removed by sending raw RPCs from an administrative connection. Settings now has a Plugins page on web and desktop: add a directory, review its files and digest before approving, enable, disable, resume, check files again and remove. Event delivery is shown beside the process state, and retrying or stopped delivery offers Resume. Controls need access:write from the current session read and a live catalogue; a standard pairing sees the list read-only. Mobile shows the same catalogue, states and details read-only, with a notice to manage plugins from an administrative web or desktop connection: the mobile app always pairs with standard scopes, so it has no access:write. The client-runtime catalogue subscription and the shared presentation model keep web and mobile on the same states and copy. The five per-feature plugin pages are rewritten into one guide, docs/user/plugins.md. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

…lugins Deselecting every environment on the Plugins screen said to update T3 Code, even when every connected server supports plugins. It now asks to select an environment, as the usage screens do. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Plugins could declare settings and secrets, but the only way to save them was a raw plugins.settings.update request. Each installed plugin that declares settings now gets a form under Settings > Integrations on web and desktop. Secrets are write-only (the form shows only whether one is saved, with Clear), and values are checked against the field before they are sent. Saving needs access:write from the current session read. A standard pairing sees the values read-only, and every save path (submit, reset or clear, choices, switches) refuses at dispatch, not only through disabled controls. Mobile lists each plugin's saved values read-only on the environment's settings screen (secrets only as saved or not set), and says to edit them from an administrative web or desktop connection: the mobile app always pairs with standard scopes. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

Adds Install from npm next to Add plugin on web and desktop, a review of the downloaded package (name, version, registry, sha512 integrity, scripts policy) before approval, Discard for an unapproved download, and an Updates section that downloads, reviews and applies a new version bound to the digest the user acknowledged. Only servers that report the pluginNpm capability get the entry or any npm request, and every step needs administrative access, as on the server. The removal confirmation says what happens to the files for each origin, and that saved settings and storage are deleted. Mobile shows where a plugin came from, read-only: the npm package on its row, and Package and Integrity in its details. Installing and updating stay on web and desktop, because the mobile app pairs with standard scopes. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

…the list A staged npm download of the installed version still needs to be applied or discarded, but the plugin row hid it because only a new version counted. The row now says a download is ready to review whenever one is staged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
