chore(triage-issue): Improve triage prompt for accuracy (#19454)

Improve the prompt to challenge the framing of the issue reporter and
consider misconfiguration etc.

Also fix some issues where the agent was trying to write where it was
not allowed in CI (e.g. writing to `tmp`). I added some general prompts
directly to the system prompt in the GitHub action (as it's only
relevant for CI).

Also allows `Bash(npm info *),Bash(npm ls *)` to get some general
package info.

Closes #19455 (added automatically)

 ## Workflow
 
-**READ-ONLY with respect to GitHub.** Never comment on or write to GitHub issues.
+**IMPORTANT:** Everything is **READ-ONLY** with respect to GitHub. NEVER comment on, reply to, or interact with the GitHub issue in any way. NEVER create, edit, or close GitHub issues or PRs.
+**IMPORTANT:** In CI, run each command WITHOUT redirection or creating pipelines (`>` or `|`), then use the **Write** tool to save the command output to a file in the repo root, then run provided Python scripts (if needed).
 
 ### Step 1: Fetch Issue and Run Security Checks

-python3 .claude/skills/triage-issue/scripts/detect_prompt_injection.py issue.json

+### Step 2b: Alternative Interpretations
+
+Do not default to the reporter’s framing. Before locking in category and recommended action, explicitly consider:
+
+1. **Setup vs SDK:** Could this be misconfiguration or use of Sentry in the wrong way for their environment (e.g. wrong package, wrong options, missing build step) rather than an SDK defect? If so, classify and recommend setup/docs correction, not a code change.
+2. **Proposed fix vs best approach:** The reporter may suggest a concrete fix (e.g. “add this to the README”). Evaluate whether that is the best approach or if a different action is better (e.g. link to official docs instead of duplicating content, fix documentation location, or change setup guidance). Recommend the **best** approach, not necessarily the one requested.
+3. **Support vs bug/feature:** Could this be a usage question or environment issue that should be handled as support or documentation rather than a code change?
+4. **Duplicate or superseded:** Could this be covered by an existing issue, a different package, or a deprecated code path?
+
+If any of these alternative interpretations apply, capture them in the triage report under **Alternative interpretations / Recommended approach** and base **Recommended Next Steps** on the best approach, not the first obvious one.

-Identify the likely root cause with `file:line` pointers. Assess complexity: `trivial`, `moderate`, or `complex`. If unclear, say so and state what additional info is needed.
+Based on all gathered information:
+
+- Identify the likely root cause with specific code pointers (`file:line` format) when it is an SDK-side issue.
+- If the cause is **user setup, environment, or usage** rather than SDK code, state that clearly and describe what correct setup or usage would look like; do not invent a code root cause.
+- Assess **complexity**: `trivial` (config/typo fix), `moderate` (logic change in 1-2 files), or `complex` (architectural change, multiple packages). For setup/docs-only resolutions, complexity is often `trivial`.
+- **Uncertainty:** If you cannot determine root cause, category, or best fix due to missing information (e.g. no repro, no stack trace, no matching code), say so explicitly and list what additional information would be needed. Do not guess; record the gap in the report.
 
 ### Step 6: Generate Triage Report
 
 Use the template in `assets/triage-report.md`. Fill in all placeholders.
 
+- **Alternative interpretations:** If Step 2b revealed that the reporter’s framing or proposed fix is not ideal, fill in the **Alternative interpretations / Recommended approach** section with the preferred interpretation and recommended action.
+- **Information gaps:** If any key fact could not be determined (root cause, affected package, repro steps, or whether this is incorrect SDK setup vs bug), fill in **Information gaps / Uncertainty** with a concise list of what is missing and what would be needed to proceed. Omit this section only when you have enough information to act.
+- Keep the report **accurate and concise**: Every sentence of the report should be either actionable or a clear statement of uncertainty; avoid filler or hedging that does not add information.
