 Generate a comprehensive, prioritized issue triage report for the `modelcontextprotocol/csharp-sdk` repository. The C# SDK is **Tier 1** ([tracking issue](https://github.com/modelcontextprotocol/modelcontextprotocol/issues/2261)), so apply the Tier 1 SLA thresholds (for triage, P0 resolution, and other applicable timelines) as defined in the live Tier 1 requirements fetched from `sdk-tiers.mdx` in Step 1. **Triage** means the issue has at least one type label (`bug`, `enhancement`, `question`, `documentation`) or status label (`needs confirmation`, `needs repro`, `ready for work`, `good first issue`, `help wanted`).

-### Step 2: Fetch All Open Issues
+### Step 2: Gather Prior Triage Reports
 
-Paginate through all open issues in `modelcontextprotocol/csharp-sdk` via the GitHub API. For each issue, capture:
+Search the **workflow repository** (where this workflow is running) for triage report issues — both open **and** closed — whose title starts with `[C# SDK Issue Triage] ` and that were created or updated within the last **4 weeks**. The workflow repository may be a fork or side repo, or it may be `modelcontextprotocol/csharp-sdk` itself; search whichever repo this workflow is running in.
+
+For each matching issue found:
+
+1. Read the issue **body** (the triage report from that run).
+2. Read **all comments** on the issue (these may contain maintainer feedback, action items, or guidance).
+3. Note whether the issue is open or closed and its date.
+
+If there is currently an open triage report issue, record its issue number for later use in the publishing step.
+
+Retain this prior-run context for use in Step 9 when generating the report:
+
+- **Trends:** Compare the current triage state with prior reports to note new issues since last run, issues that were resolved, and changes in SLA compliance over the 4-week window.
+- **Maintainer guidance:** If comments on any triage report issue contain instructions (e.g., "plan to close #42 next sprint", "this is intentionally kept open"), incorporate that context into the assessment and recommendations.
+- **Stability:** When an issue's status has not changed since the last report, you may carry forward the previous assessment rather than restating it from scratch — but always verify it is still accurate.
+
+If no matching triage report issues exist, proceed without prior-run context.
+
+### Step 3: Fetch All Open Issues
+
+Paginate through all open issues in `modelcontextprotocol/csharp-sdk` (always the upstream repo, regardless of where this workflow is running) via the GitHub API. For each issue, capture:
 - Number, title, body (description)
 - Author and author association (member, contributor, none)
 - Created date, updated date
 - All labels
 - Comment count
 - Assignees
 
-### Step 3: Classify Triage Status
+**Exclude** any issue labeled `automation` from the triage data set. These are workflow-generated issues (e.g., triage reports, tier audits) and are not part of the SDK issue backlog.
+
+### Step 4: Fetch Recent Pull Requests
+
+Fetch open **and** recently closed/merged pull requests from `modelcontextprotocol/csharp-sdk` (always the upstream repo). Include PRs that were merged or updated within the last 4 weeks. For each PR, capture:
+- Number, title, state (open, closed, merged)
+- Linked issues (from the PR body, e.g., "Fixes #N", "Closes #N", "Resolves #N")
+- Merge date (if merged)
+- Author
+
+Use this data during the deep-dive review (Step 7) to:
+- Identify issues that may already be resolved by merged PRs but haven't been closed yet.
+- Note issues with open PRs that are actively being worked on.
+- Recommend "Link to PR" or "Close — resolved by PR #N" in the issue's next-step recommendations.
