Triage Frontend Issues

Archive non-actionable noise from the sentry/javascript issue queue: only archive, always untilEscalating, always with a stated reason. Issues that look actionable in our code, or that you cannot confidently classify, must be skipped.

Hard Rules

These rules override anything else. Do not relax them.

1. Project scope. Only operate on organizationSlug=sentry, project slug javascript. If asked to triage a different project, stop and ask the user to confirm.
2. Archive only. The only status mutation permitted is status=ignored. Never resolve, never unresolve, never assign, never delete, never bulk-update fields other than status.
3. Always untilEscalating. Use ignoreMode=untilEscalating. Never use forever, forDuration, untilOccurrenceCount, or untilUserCount. If the user asks for a different mode, stop and have them archive that issue manually — this skill does not perform non-escalating archives.
4. Always include a reason. The reason must be a short, factual sentence naming the category from references/archive-criteria.md (e.g., "Third-party library noise — echarts internals; not actionable in our code").
5. Never touch issues outside the unresolved queue. Skip anything with status of resolved, ignored, or reprocessing.
6. Never archive without confirmation. Build a full plan, show it to the user, wait for explicit approval before calling update_issue. A single approval covers the displayed plan only; new batches need new approval.
7. When in doubt, skip. If an issue could plausibly be a real bug in our code, do not archive it. Surface it as needs-human in the plan with a one-line note.

Prerequisites

• Sentry MCP authenticated via mcp.sentry.dev. Required tools: search_issues, get_sentry_resource, update_issue.
• If update_issue is not available, stop and ask the user to authenticate the Sentry MCP server.

Inputs

$ARGUMENTS is one of:

If $ARGUMENTS is ambiguous, ask the user to clarify before searching.

Workflow

1. Load the queue

For single-issue input:

• Call get_sentry_resource(url=<issue-url>) or get_sentry_resource(resourceType='issue', organizationSlug='sentry', resourceId=<shortId>).
• Confirm Project is the javascript frontend project. If not, stop.

For query/default input:

• Call search_issues(organizationSlug='sentry', projectSlugOrId='javascript', query=<query>, sort='new', limit=50).
• Then call get_sentry_resource for each result in parallel to get culprit, substatus, assignee, and stack-frame hints (the search response omits some fields).

Skip immediately if any of these are true on an issue:

• status is not unresolved (already archived, resolved, or in reprocessing).
• assignedTo is set to a human (someone is already owning it).
• assignedTo is set to a team other than frontend/issues and the issue looks team-specific (let the owning team triage).

2. Classify each issue

Read references/archive-criteria.md for the category taxonomy with recognition heuristics and examples. For each candidate issue, produce one of:

When evaluating, weight these signals (in this order):

1. Top non-Sentry-SDK frame. If the top in-app frame is in node_modules/, chrome-extension://, a third-party host, or <unknown>, this is a strong archive signal.
2. Title pattern. Many archives are recognizable from the title alone (see criteria reference).
3. Volume is not a veto. Some high-volume issues (10k+ events, thousands of users) are still archive-worthy if the top frame is third-party. Volume alone never forces archive either.
4. Recency. Single-event issues older than 30 days with no recurrence are usually noise.
5. Customer org spread. If events come from one customer subdomain only (check customerDomain.subdomain tag), it is likely customer-environment noise.

3. Build the plan

Output one Markdown table to the user, in this exact shape:

## Triage plan — sentry/javascript (<N> candidates)

| # | Issue | Title | Volume | Decision | Category | Reason |
|---|-------|-------|--------|----------|----------|--------|
| 1 | [JAVASCRIPT-XXXX](url) | TypeError: ... | 12e/3u | archive | browser-api-noise | Browser clipboard permission denied; not actionable. |
| 2 | [JAVASCRIPT-YYYY](url) | <unknown> | 4945e/123u | needs-human | — | High volume, no title — please review before archiving. |
| 3 | [JAVASCRIPT-ZZZZ](url) | ZodError: ... | 360e/132u | skip | — | Schema validation failure in our code; looks actionable. |

Then summarize counts: N archive / M skip / K needs-human. End with:

Reply `apply` to archive the N issues marked `archive`, `apply N,M,...` to archive a subset, or `cancel` to take no action.

4. Apply on approval

When the user replies apply (or apply <subset>):

For each issue in the approved set, call:

update_issue(
  organizationSlug='sentry',
  issueId=<shortId>,
  status='ignored',
  ignoreMode='untilEscalating',
  reason=<category-tagged reason from the plan>,

Run these sequentially (not in parallel). If a call fails, log the failure, continue with the remaining issues, and report the failed IDs in step 5.

If the user replies cancel or asks to modify the plan, do NOT call update_issue. If they reply with edits ("change row 2 to skip"), rebuild the plan and re-confirm.

5. Report

After applying, output:

Recovery

• If update_issue fails on one item, log the failure and continue with the rest. Report failed IDs at the end.
• If the user notices a wrong archive, the user can unarchive it themselves in Sentry. The skill never reverses its own actions automatically.
• If the user asks "redo the plan with these tweaks" mid-flow, regenerate the plan from scratch — do not assume the previous plan still applies.

Example reasons (use this voice)

• Third-party library noise — echarts tooltip; not actionable in our code.
• Browser API permission noise — Clipboard writeText denied by user agent.
• Customer-environment proxy interference — 200 response treated as error (HTML body from corporate proxy).
• Transient backend 5xx — InternalServerError on /api/0/organizations/.../events-meta/; backend transient.
• Test/synthetic event — smoke test or security probe, not production traffic.
• Wrong project — Prisma/Python error mis-routed to frontend project.
• Single-event fluke — 1 event, 1 user, no recurrence in 30+ days.
• Browser extension noise — ReferenceError for extension-injected global (DarkReader/WeixinJSBridge).
