+
+# Triage Issue Skill
+
+You are triaging a GitHub issue for the `getsentry/sentry-javascript` repository.
+
+## Input
+
+The user provides: `<issue-number-or-url> [--ci]`
+
+- **Required:** An issue number (e.g. `1234`) or a full GitHub URL (e.g. `https://github.com/getsentry/sentry-javascript/issues/1234`)
+- **Optional:** `--ci` flag — when set, format output as a Linear payload stub instead of a terminal report
+
+Parse the issue number from the input. If a URL is given, extract the number from the path.
+
+## Workflow
+
+Follow these steps in order. Use tool calls in parallel wherever steps are independent.
+
+### Step 1: Fetch Issue Details
+
+- Run `gh api repos/getsentry/sentry-javascript/issues/<number>` to get the title, body, labels, reactions, and state.
+- Run `gh api repos/getsentry/sentry-javascript/issues/<number>/comments` to get the conversation context.
+
+### Step 2: Classify the Issue
+
+Based on the issue title, body, labels, and comments, determine:
+
+- **Category:** one of `bug`, `feature request`, `documentation`, `support`, `duplicate`
+- **Affected package(s):** Identify which `@sentry/*` packages are involved. Look at:
+  - Labels (e.g. `Package: browser`, `Package: node`)
+  - Stack traces in the body
+  - Code snippets or import statements mentioned
+  - SDK names mentioned in the text
+- **Priority:** `high`, `medium`, or `low` based on:
+  - Number of reactions / thumbs-up (>10 = high signal)
+  - Whether it's a regression or data loss issue (high)
+  - Crash/error frequency signals (high)
+  - Feature requests with few reactions (low)
+  - General questions or support requests (low)
+
+### Step 3: Codebase Research
+
+Search for relevant code in the local sentry-javascript repository:
+
+- Use Grep/Glob to find error messages, function names, and code paths mentioned in the issue.
+- Look at stack traces and find the corresponding source files.
+- Identify the specific code that is likely involved.
+
+Then search cross-repo for related context:
+
+- Search `getsentry/sentry-javascript-bundler-plugins` via: `gh api search/code -X GET -f "q=<search-term>+repo:getsentry/sentry-javascript-bundler-plugins"`
+- Search `getsentry/sentry-docs` via: `gh api search/code -X GET -f "q=<search-term>+repo:getsentry/sentry-docs"`
+
+Pick 1-3 targeted search terms from the issue (error messages, function names, config option names). Do NOT search for generic terms.
+
+### Step 4: Related Issues & PRs
+
+- Search for duplicate or related issues: `gh api search/issues -X GET -f "q=<search-terms>+repo:getsentry/sentry-javascript+type:issue"`
+- Search for existing fix attempts: `gh pr list --repo getsentry/sentry-javascript --search "<search-terms>" --state all --limit 5`
+
+### Step 5: Root Cause Analysis
+
+Based on all gathered information:
+
+- Identify the likely root cause with specific code pointers (`file:line` format)
+- Assess **complexity**: `trivial` (config/typo fix), `moderate` (logic change in 1-2 files), or `complex` (architectural change, multiple packages)
+- If you cannot determine a root cause, say so clearly and explain what additional information would be needed.
+
+### Step 6: Generate Triage Report
+
+Output the following structured report:
+
+```
+## Issue Triage: #<number>
+
+**Title:** <title>
+**Classification:** <bug|feature request|documentation|support|duplicate>
+**Affected Package(s):** @sentry/<package>, ...
+**Priority:** <high|medium|low>
+**Complexity:** <trivial|moderate|complex>
+
+### Summary
+<1-2 sentence summary of the issue>
+
+### Root Cause Analysis
+<Detailed explanation with file:line code pointers. Reference specific functions, variables, and logic paths.>
+
+### Related Issues & PRs
+- #<number> - <title> (<open|closed|merged>)
+- (or "No related issues found")
+
+### Cross-Repo Findings
+- **bundler-plugins:** <findings or "no matches">
+- **sentry-docs:** <findings or "no matches">
+
+### Recommended Next Steps
+1. <specific action item>
+2. <specific action item>
+3. ...
+```
+
+### Step 7: Suggested Fix Prompt
+
+If a viable fix is identified (complexity is trivial or moderate, and you can point to specific code changes), include a copyable prompt block:
+
+```
+### Suggested Fix
+
+Complexity: <trivial|moderate|complex>
+
+To apply this fix, run the following prompt in Claude Code:
+
+\`\`\`
+Fix GitHub issue #<number> (<title>).
+
+Root cause: <brief explanation>
+
+Changes needed:
+- In `packages/<pkg>/src/<file>.ts`: <what to change>
+- In `packages/<pkg>/test/<file>.test.ts`: <test updates if needed>
+
+After making changes, run:
+1. yarn build:dev
+2. yarn lint
+3. yarn test (in the affected package directory)
+\`\`\`
+```
+
+If the issue is complex or the fix is unclear, skip this section and instead note in the Recommended Next Steps what investigation is still needed.
+
+### Step 8: Output Based on Mode
+
+- **Default (no `--ci` flag):** Print the full triage report directly to the terminal. Do NOT post anywhere, do NOT create PRs, do NOT comment on the issue.
+- **`--ci` flag:** Format the triage report as a Linear payload stub and print it. Include a `TODO` note that this will be connected to Linear via MCP/API integration in the future. The stub should look like:
+
+```json
+{
+  "TODO": "Connect to Linear API or MCP tool to post this payload",
+  "teamId": "JAVASCRIPT_SDK_TEAM_ID",
+  "title": "Triage: #<number> - <title>",
+  "description": "<full triage report in markdown>",
+  "priority": <1-4>,
+  "labels": ["triage", "<category>"]
+}
+```
+
+## Important Rules
+
+- Do NOT modify any files in the repository.
+- Do NOT create branches, commits, or PRs.
+- Do NOT comment on the GitHub issue.
+- Do NOT post to any external services (unless `--ci` is specified, and even then only print the payload).
+- Focus on accuracy: if you're uncertain about the root cause, say so rather than guessing.
+- Keep the report concise but thorough. Developers should be able to act on it immediately.

+  First, check the GitHub issue comments (already fetched in Step 1) for a Linear linkback comment. Extract the issue identifier (e.g. `JS-1669`) from the comment body.

+
+  **Step 8e: Post the triage comment**
+
+  **CRITICAL: Always use Python to build and write the JSON payload to a temp file.** Do NOT use shell heredocs (`<<EOF`), string interpolation, or `cat` to construct JSON — this causes escaping issues with `$`, backticks, and newlines that silently corrupt the payload or produce duplicate requests.
+
+  ```python
+  python3 -c '
+  import json, os, tempfile
+
+  issue_id = "<LINEAR_ISSUE_UUID>"  # from Step 8c
+  comment_body = "<TRIAGE_REPORT_CONTENT>"  # the full triage report text

+      "variables": {
+          "input": {
+              "issueId": issue_id,
+              "body": comment_body
+          }
+      }
+  }
+
+  fd, path = tempfile.mkstemp(suffix=".json")
+  with os.fdopen(fd, "w") as f:
+      json.dump(payload, f)
+  print(path)
+  '
+  ```
+
+  Then POST the payload file and parse the response:
+
+  ```bash
+  RESPONSE=$(curl -s -X POST https://api.linear.app/graphql \
+    -H "Content-Type: application/json" \
+    -H "Authorization: Bearer $LINEAR_ACCESS_TOKEN" \
+    -d @"$PAYLOAD_FILE")
+  rm -f "$PAYLOAD_FILE"
+  ```
+
+  Parse `$RESPONSE` using Python. Print only:
+  - On success: `Triage comment posted on <identifier>: <url>`
+  - On failure: `Failed to post triage comment: <error message from response body>`
+
+  If the API call fails, fall back to printing the full report to the terminal.
 
 ## Important Rules
 
 - Do NOT modify any files in the repository.
 - Do NOT create branches, commits, or PRs.
 - Do NOT comment on the GitHub issue.
-- Do NOT post to any external services (unless `--ci` is specified, and even then only print the payload).
+- Do NOT post to external services unless `--ci` is specified.
+- When `--ci` is specified, only post a comment on the existing Linear issue — do NOT create new Linear issues, and do NOT post anywhere else.
+- **NEVER print, log, or expose API keys, tokens, or secrets in conversation output.** Only reference them as `$ENV_VAR` in Bash commands.
 - Focus on accuracy: if you're uncertain about the root cause, say so rather than guessing.
 - Keep the report concise but thorough. Developers should be able to act on it immediately.

-    -d '{"query": "{ issue(id: \"JS-XXXX\") { comments { nodes { body } } } }"}')
-  ```
-
-  Check if any comment body starts with `## Automated Triage Report`. If one already exists, print `"Triage comment already exists on <identifier>, skipping"` and exit without posting.
+  Use the Python script at `assets/post_linear_comment.py` to handle the entire Linear API interaction. This avoids all shell escaping issues with GraphQL (`$input`, `CommentCreateInput!`) and markdown content (backticks, `$`, quotes).
 
-  **Step 8e: Post the triage comment**
+  The script reads `LINEAR_CLIENT_ID` and `LINEAR_CLIENT_SECRET` from environment variables (set from GitHub Actions secrets), obtains an OAuth token, checks for duplicate triage comments, and posts the comment.
 
-  **CRITICAL: Always use Python to build and write the JSON payload to a temp file.** Do NOT use shell heredocs (`<<EOF`), string interpolation, or `cat` to construct JSON — this causes escaping issues with `$`, backticks, and newlines that silently corrupt the payload or produce duplicate requests.
+  1. **Write the report body to a temp file** using the Write tool (not Bash). This keeps markdown completely out of shell.
 
-  ```python
-  python3 -c '
-  import json, os, tempfile
+     Write the triage report to `/tmp/triage_report.md`.
 
-  issue_id = "<LINEAR_ISSUE_UUID>"  # from Step 8c
-  comment_body = "<TRIAGE_REPORT_CONTENT>"  # the full triage report text
+  2. **Run the script:**
 
-  payload = {
-      "query": "mutation CommentCreate($input: CommentCreateInput!) { commentCreate(input: $input) { success comment { id body } } }",
-      "variables": {
-          "input": {
-              "issueId": issue_id,
-              "body": comment_body
-          }
-      }
-  }
+     ```bash
+     python3 .claude/skills/triage-issue/assets/post_linear_comment.py "JS-XXXX" "/tmp/triage_report.md"
+     ```
 
-  fd, path = tempfile.mkstemp(suffix=".json")
-  with os.fdopen(fd, "w") as f:
-      json.dump(payload, f)
-  print(path)
-  '
-  ```
+  If the script fails (non-zero exit), fall back to printing the full report to the terminal.
 
-  Then POST the payload file and parse the response:
+  Clean up temp files after:
 
   ```bash
-  RESPONSE=$(curl -s -X POST https://api.linear.app/graphql \
-    -H "Content-Type: application/json" \
-    -H "Authorization: Bearer $LINEAR_ACCESS_TOKEN" \
-    -d @"$PAYLOAD_FILE")
-  rm -f "$PAYLOAD_FILE"
+  rm -f /tmp/triage_report.md
   ```
 
-  Parse `$RESPONSE` using Python. Print only:
-  - On success: `Triage comment posted on <identifier>: <url>`
-  - On failure: `Failed to post triage comment: <error message from response body>`
-
-  If the API call fails, fall back to printing the full report to the terminal.
-
 ## Important Rules
 
 - Do NOT modify any files in the repository.

   Use the Python script at `assets/post_linear_comment.py` to handle the entire Linear API interaction. This avoids all shell escaping issues with GraphQL (`$input`, `CommentCreateInput!`) and markdown content (backticks, `$`, quotes).
 
   The script reads `LINEAR_CLIENT_ID` and `LINEAR_CLIENT_SECRET` from environment variables (set from GitHub Actions secrets), obtains an OAuth token, checks for duplicate triage comments, and posts the comment.
