Closed upstream submission. The maintainer closed this PR for conflicts and requested a fresh PR from current main. This closed PR remains at its archived head; it has not been reopened. The reviewed corrections and main integration are preserved at d79284be79a and in the open counterpart PR. The checks and capture identities below describe the archived submission, not the newly published counterpart. Platform #33606 was also closed unmerged.

Server plugins cannot read the files in the thread they serve through the public SDK. Server API version 2 adds workspace.listEntries({ threadId, directoryPath? }) and workspace.readFile({ threadId, relativePath }).

Each call resolves the active thread and project, uses the thread worktree or project folder, and reuses the existing shallow listing and bounded text reader. Absolute paths, traversal and symlinks outside the workspace are refused. The SDK README includes an MCP tool example. This is a read-only API for trusted plugins, with the existing 1 MiB text limit. Reads under .git retain existing workspace behavior; errors can include host paths. There is no Files renderer or editing API in this slice, and no client UI change.

Depends on the plugin platform #33606, which is not merged. This branch preserves ashx-j's platform and Maria's follow-up commits, rebased onto main ddc4f576. Their branches and PR ownership are unchanged. The full upstream diff includes that prerequisite. Review the feature and follow-up fixes. Paired PR: ashx-j#32.

Published head c780dff2081 adds the shared platform review corrections: structured host lifecycle errors that retain the original cause and existing plugin diagnostics, route-visibility styling owned by SidebarInset, and removal of one static home-region test. The additive feature behavior is unchanged. The earlier ancestry-only merge 66285781965 is retained, keeping the original author base as an ancestor without retargeting either PR. Platform owner refs remain untouched.

Verification on this source tree: CI=true VITEST_MAX_WORKERS=1 vp run check:changed origin/main passed all stages: 1,100 tests in 79 files, 42 package typechecks, format, lint, knip, GraphQL, unused patches and React Compiler. The frozen tree fac078efb3e434587fa854c78a0cc1c42f072d8e matches the committed tree exactly; commit hooks passed. Focused shared-patch verification in the workspace tree passed 42 server tests and 13 browser tests. A fresh independent GPT-6.1 Sol review (high reasoning, Codex harness) approved the exact six-file patch across all three branches with no actionable findings; its additional runtime check passed 27 stage/cause combinations. The earlier isolated Linux suite passed 249 tests in 37 files before this shared follow-up; it was not repeated for these edits. All eight required upstream checks passed on c780dff2081; live upstream checks.

The refresh retains main's MCP tool search, settings translations/accessibility, and current composer dictation/submission behavior. The shared browser test now selects the “New thread in…” submenu by name instead of assuming an optional project row exists; Enter activation and project highlight assertions remain. No production keyboard behavior, timeout or retry changed. At the previous publication, all three branches merged cleanly with newer main ed54f306; that later main revision was checked for merge conflicts, not represented as the tested base.

Landing gates: this is additive feature work dependent on the unmerged platform. Upstream's current contribution policy requires a maintainer request for feature PRs; this description makes no claim that such a request or merge approval has been given. Approvability also requires human review of platform/default-primary-environment loading, diagnostic suppressions and intentional plugin exception-text exposure; those gates remain open. Macroscope correctness review was cost-limited and was not bypassed or retriggered. GitHub's clean merge result is not a merge-readiness verdict. Kept open and unmerged; tracked in saphid/personal-ops#128.

Created and integrated with Claude Opus 5.5 in Claude Code and GPT-6.1 Sol in Codex through T3 Code. Fresh integration and shared-fix reviews: GPT-6.1 Sol, high reasoning, Codex harness.

The new error paths copy arbitrary plugin exception text into reason and expose it through RPC; bounding it does not make defect text safe under this check's error convention. Please normalize failures into structured categories and retain exact exceptions only as cause. The same correction is needed for PluginMcpToolError and the persisted load/activation failure messages; preserve caller-visible behavior explicitly when restructuring.

Note

🤖 GPT-6.1 Sol responding on behalf of saphid

Plugin-owned diagnostic text remains unchanged in RPC/MCP failures, failed-plugin rows and cleanup logs. The SDK explicitly promises that a thrown tool error reaches the agent, and the user guide promises the failed-plugin reason. This deliberate inherited behavior is not an exception currently named in effect-services.md; changing the public diagnostic contract or approving an exception needs a maintainer decision. Leaving this thread unresolved and the exception-exposure gate open. The internal structured-error fix does not settle that policy question.

Inspected source.

Merge Risk: Moderate · up to c780d

Several previously reported plugin-platform problems are still open. The most important are possible credential text in plugin failure logs and published failures, plugin storage writes continuing after a plugin is disabled, saved plugin switches being deleted when discovery stops at its directory limit, and settings edits being lost during an in-flight save. These should be resolved or explicitly accepted before merge.

Full details: Title check

Explanation

The title "feat(plugins): read files from a thread workspace" is a conventional commit title that matches the main change: the PluginWorkspace service and the workspace.listEntries and workspace.readFile plugin API methods that read files from a thread's worktree or project folder. It is specific and scannable. It omits the server API version bump and the MCP tool example, which are minor, so it is not a full summary of the changeset.

Full details: Description check

Explanation

The description covers the problem and scope of the change: read-only workspace access for trusted plugins, the two new API methods, path and symlink restrictions, the 1 MiB limit, and the .git and host-path behavior. It also gives extensive verification results and landing-gate notes. However, it does not follow the repository template. It lacks the required '## Problem', '## Change', '## Scope', and '## Verification' headings. It also does not link a bug issue, which the template requires for the scope check. The feature is framed as additive work, not a bug fix, and the description says a maintainer request is not confirmed. Its Verification section is detailed but mixes in platform-branch and review-process content. Most required information is present, so the check passes, but the template structure should be applied and the scope justification clarified.

Resolution

Restructure the description to match the template headings (Problem, Change, Scope, Verification). Under Scope, state that this is a feature and link the maintainer request that the contribution policy requires. Keep the verification notes focused on the changed workspace behavior.

If the system uses light appearance and the page is pinned dark, this line applies the dark canvas. Line 368 still selects the light-appearance symbol color, #1f2937. On Windows and Linux, the transparent title-bar overlay can therefore show dark window controls against a dark page.

A t3-secret field without an exact type: "string" is stored and sent to clients as plain text.

secretFields treats a field as a secret only when property.type === "string". A plugin manifest can declare token: { format: "t3-secret" } or token: { type: ["string", "null"], format: "t3-secret" }. In both cases fields does not contain token. update then writes the value into settings.json, and getForClient returns it without SECRET_REDACTED. The plugin author asked for secret storage and gets plain-text storage, with no warning.

Do one of these:

• Treat format: "t3-secret" as the marker for a secret, whatever the declared type.
• Make settingsSchemaProblem reject a t3-secret field whose type is not exactly "string", so the installer refuses that manifest.

Refold needs a second qualifying input after the composer reopens.

noteReaderScroll records the scroll position only on the first qualifying input after the reader reopens the composer. The next qualifying input compares against that position. One discrete input, such as a single mouse-wheel notch, one arrow or page key, or a scrollbar press, can move the timeline 24 px or more without a later input. The composer then stays open until the reader sends another qualifying input.

Scroll-source notifications do not cover this gap. Lines 397–403 exclude "scroll" navigation, and handleScroll emits it only when a frame has input.

Compare the movement after the browser applies the input, for example in a follow-up animation frame, so one input can satisfy the 24 px rule.

180-190: Minor · Functional Correctness · Quick win

Give the search shortcut one owner on settings pages.

On a settings route, the page-placement nav in the modal and the sidebar-placement nav both mount. Each registers a window keydown listener. The first listener calls preventDefault(), so the second returns at its defaultPrevented check. The shortcut therefore focuses whichever nav registered first, which can be the nav the user is not viewing. That nav's search field is also not focused. Choose one active owner for / and Find, such as the visible placement, and make the other listener skip the event.

Possible approach

Gate the page-placement listener on whether the sidebar nav is shown. Read sidebarSettingsNavShownAtom in SettingsSidebarNav and return early from the page-placement listener when it is true. Confirm the desired owner first. This change is not yet verified.

Keep web and style failures separate.

The web loader and style loader both write this key. If a stylesheet fails and the web loader starts later, the web loader clears the stylesheet failure while it remains active. The Plugins page then loses the failure message. Store failures by source and derive the displayed message from the active failures.
