A GitHub Copilot canvas for on-call error triage. It scans your live Sentry issues, groups them by why they need attention, and lets you hand a selected issue off to Copilot — either to file a tracking issue or to spin up a session that drafts a fix pull request.

Features

Live scan of Sentry issues for an organization (optionally narrowed to a single project), grouped by urgency.
Plain-English titles toggle that rewrites the raw Sentry error into a one-sentence, user-facing summary.
Tracking detection so already-triaged issues (filed with the sentry-triage label) are recognized on later scans.
📝 Create issue files or reuses a tracking issue only — no code, branch, or PR.
🔧 Fix with Copilot files/reuses the tracking issue and spawns a dedicated session that drafts a fix PR.
Settings panel to confirm the repository, local checkout, base branch, and issue tracker before anything is created.

Prerequisites

Node.js 22 or newer.
The GitHub Copilot app canvas / UI-extensions experiment enabled.
A Sentry sign-in. This canvas reads issues through the Sentry CLI in library mode — there is no MCP server to configure. After installing the dependency (see Install below), sign in once with the package-local CLI, run from the extension folder:
```
npx sentry auth login
```
This stores an OAuth credential the canvas auto-detects. For non-interactive environments, export a token instead:
```
export SENTRY_AUTH_TOKEN=<your-token>
```
The login or token needs these scopes: event:read, org:read, project:read. The canvas checks for a valid sign-in each time it opens; if you aren't signed in it shows a setup gate with the exact reason.

Install

Drop this folder at ~/.copilot/extensions/sentry-triage/ for user scope, or in a repository at .github/extensions/sentry-triage/ for project scope.

This canvas depends on the sentry npm package at runtime, which isn't bundled with the extension source. If it's missing, the canvas still opens and shows a setup gate explaining what to do instead of crashing.

Let Copilot set it up (recommended)

Because the canvas runs inside GitHub Copilot, the agent can install the dependency for you. Paste this into Copilot:

Locate the loaded sentry-triage canvas extension folder — the directory that contains its package.json — run npm install there, then reload extensions.

(That folder is ~/.copilot/extensions/sentry-triage/ for user scope, .github/extensions/sentry-triage/ for project scope, or, if you installed the published plugin, com.github.copilot/extensions/sentry-triage inside the installed plugin.)

Then finish the one interactive step yourself — sign in so Copilot never handles a raw secret. Run this from the same extension folder (npx resolves the CLI the local npm install just placed in node_modules):

npx sentry auth login

Or install it manually

# User scope
cd ~/.copilot/extensions/sentry-triage

# Or project scope, from the repository root
cd .github/extensions/sentry-triage

# Or, if you installed the published plugin (`copilot plugin install`), the source
# lives inside the installed plugin — cd into its extension folder:
cd <installed-plugin-path>/com.github.copilot/extensions/sentry-triage

npm install
npx sentry auth login

Reload extensions in the GitHub Copilot app, then open the sentry-triage canvas.

Open the canvas in the correct repository scope

Open the canvas from a Copilot session scoped to the repository where you want issues and draft pull requests created, so it can detect the repository, local checkout, and base branch automatically. If you opened it outside the intended repository, open Settings and confirm the targets before selecting Create issue or Fix with Copilot.

Use the canvas

Open the canvas from the repository you want to work in.
Confirm the Sentry organization (auto-detected from your sign-in). If your account has more than one org, pick it from the dropdown. Scan issues stays disabled until an organization is set.
Optionally narrow to a single project using the autocomplete field. Leave it blank to scan the whole org.
Review the issues grouped by why they need attention. Toggle Plain-English titles to swap the raw Sentry error for a readable summary.
Select issues and choose an action in the toolbar — 📝 Create issue or 🔧 Fix with Copilot.

Agent tools

The canvas exposes structured hand-off tools the agent calls instead of printing JSON into the timeline: submit_issue_summaries, submit_tracking, submit_related, and submit_work_pr.
