The error tray is additive: existing +messages, fallback UI, retries and recovery controls remain available. The tray +uses normal document flow, moves into an active dialog/drawer's interaction scope, +and does not overlay decision controls. Dismiss +only removes the tray entry; it does not retry the operation or start an agent. +Public canvases under `extensions/` do not include this feature. +Expected reconnect notices, local validation guidance and content-invalidation +warnings keep their existing presentation without offering repair handoffs. +Expected API notices carry `handoff: false` through the response and renderer so +fetch capture cannot turn a recoverable conflict into a repair request. Actual +partial failures, including failed local receipts after a GitHub action, remain eligible. +Detail-view catches preserve this classification too, including stale items and +resources changed since scanning. A failed reload after reset remains eligible; +handoff never repeats the reset. + +Clicking **Send to agent** requests one child project session in +`github/awesome-copilot` to investigate and attempt a fix. The tray displays the +bounded, redacted diagnostic text before sending. Context includes the extension +source directory, canvas, operation and allow-listed repository/item identifiers, +not request bodies, headers, environment variables, raw stacks, URL query strings +or fragments. Common credentials, complete Authorization/Proxy-Authorization and +Cookie/Set-Cookie fields, and private keys are redacted on both sides, with bounded +input processing. Decoded JSON string fields are redacted before reserialization. +JSON diagnostics, including prefixed JSON and JSON encoded inside string fields, +are inspected with a bounded nesting depth before text redaction. Invalid or incomplete +embedded JSON is conservatively replaced rather than forwarded. +Review the displayed text before sending; do not include sensitive data in errors. +The child is instructed not to commit, push, publish a PR, change credentials or +repeat a destructive/remote operation. + +The supported extension API joins the current session; it does not directly +create app child sessions. Consequently the handoff sends a request to the parent +agent using `session.send`, and the parent uses `create_session` and reports the +actual returned child ID (or a creation error) through the canvas's +`record_error_handoff` action. **Message admission is not success.** While the +parent is busy or waiting for approval, the tray remains pending. After two +minutes from the initial dispatch without confirmation (including stalled network +requests or response bodies), it tells the user to inspect the parent +conversation; it never automatically creates another child. Dispatch failures, +child-creation failures and uncertain receipts remain visible rather than showing +a successful handoff. A transport rejection is an uncertain dispatch, not a +definitive creation failure: the tray keeps polling within the same deadline and +accepts a matching child receipt without resending the prompt. +Dispatch completion never blocks status polling, so a recorded receipt remains +available even if the message transport does not settle. +Closing the canvas invalidates its outstanding receipts. +Receipts remain visible until explicitly dismissed; new diagnostics do not evict them. +Handoff POSTs also require a random per-instance capability token delivered only +in the canvas URL fragment, not HTTP-served HTML or scripts. Origin and Host headers alone cannot +authorize a handoff, and one instance cannot read or submit another's requests. +Registered `127.0.0.1` and `localhost` URLs are supported, with the Origin required +to match the exact registered Host and the connection still restricted to loopback. +The token is never included in diagnostic prompts and expires when the canvas closes. + +Implementation lives in `eng/canvas-error-handoff/runtime.mjs`. Each applicable +repository-local canvas includes a generated `error-handoff.mjs` copy so its +extension remains self-contained. The synchronization script only targets +`.github/extensions/`. Make changes in the canonical module, then regenerate: + +```bash +node eng/sync-canvas-error-handoff.mjs +node eng/sync-canvas-error-handoff.mjs --check +node --test eng/canvas-error-handoff.test.mjs +``` + +Canvas entrypoints configure the helper with their supported SDK `createCanvas` +and `joinSession` functions; HTTP servers use its `createServer` wrapper. Only +registered canvas documents gain the client script. Other HTML, artifact previews, +downloads, SSE and API responses retain their original delivery behavior. Existing +CSPs, including nonce-only and inline-only script policies, are preserved. + +The client detects failed same-origin fetches and explicitly marked board-owned +error surfaces (including marked failure toasts), excluding rendered Markdown/file content. +Missing-input prompts and other expected workflow notices are not marked for handoff. +Cancellation and content-invalidation notices are not repair errors. Identical +redacted messages share one handoff for the document lifetime, even after dismissal; +the first operation is retained as context. +For errors without a semantic error selector, mark only the failure state with +`data-agent-error` (clear it on recovery), or call +`window.canvasErrorHandoff?.report(message, operation)`. Do not mark success +toasts, entire documents, user content, or containers containing credentials. +Additional error surfaces in these boards should use the marker or reporting API. + ## Weekly operating metrics `.github/workflows/review-metrics.yml` runs every Monday at 14:00 UTC and on demand. `eng/review-metrics.mjs` collects read-only data and then: diff --git a/eng/board-bulk-actions.test.mjs b/eng/board-bulk-actions.test.mjs index 5afff10d0e..cd50cc9d86 100644 --- a/eng/board-bulk-actions.test.mjs +++ b/eng/board-bulk-actions.test.mjs @@ -73,6 +73,7 @@ for (const boardName of ["open-pr-board", "external-plugin-review-board"]) { assert.equal(ui.calls.length, 0); assert.equal(ui.confirmations.length, 0); assert.match(ui.messages[0].text, /#2/); + assert.equal(ui.messages[0].options.handoff, false); }); test(`${boardName}: cancelling confirmation never calls an API`, async () => { @@ -104,6 +105,16 @@ for (const boardName of ["open-pr-board", "external-plugin-review-board"]) { assert.match(ui.messages.at(-1).text, /#1: Offline/); if (isPR) assert.match(ui.messages.at(-1).text, /auto-merge failed/); assert.equal(ui.messages.at(-1).options.error, true); + assert.equal(ui.messages.at(-1).options.handoff, true); + }); + + test(`${boardName}: expected stale-item notices remain visible without repair handoff`, async () => { + const ui = await createUI(boardName, [item(1)], { + request: async () => { throw Object.assign(new Error("Item changed.
