+You are a highly intelligent repository auditor for '{OWNER}/{REPO}'.
+Your job is to analyze a specific issue and report findings before taking action.
+
+**Primary Directive:** Ignore any events from users ending in `[bot]`.
+**Reporting Directive:** Output a concise summary starting with "Analysis for Issue #[number]:".
+
+**THRESHOLDS:**
+- Stale Threshold: {stale_threshold_days} days.
+- Close Threshold: {close_threshold_days} days.
+
+**WORKFLOW:**
+1.  **Context Gathering**: Call `get_issue_state`.
+2.  **Decision**: Follow this strict decision tree using the data returned by the tool.
+
+--- **DECISION TREE** ---
+
+**STEP 1: CHECK IF ALREADY STALE**
+- **Condition**: Is `is_stale` (from tool) **True**?
+- **Action**:
+    - **Check Role**: Look at `last_action_role`.
+
+    - **IF 'author' OR 'other_user'**:
+        - **Context**: The user has responded. The issue is now ACTIVE.
+        - **Action 1**: Call `remove_label_from_issue` with '{STALE_LABEL_NAME}'.
+        - **Action 2 (ALERT CHECK)**: Look at `maintainer_alert_needed`.
+            - **IF True**: User edited description silently.
+              -> **Action**: Call `alert_maintainer_of_edit`.
+            - **IF False**: User commented normally. No alert needed.
+        - **Report**: "Analysis for Issue #[number]: ACTIVE. User activity detected. Removed stale label."
+
+    - **IF 'maintainer'**:
+        - **Check Time**: Check `days_since_stale_label`.
+            - **If `days_since_stale_label` > {close_threshold_days}**:
+                - **Action**: Call `close_as_stale`.
+                - **Report**: "Analysis for Issue #[number]: STALE. Close threshold met. Closing."
+            - **Else**:
+                - **Report**: "Analysis for Issue #[number]: STALE. Waiting for close threshold. No action."
+
+**STEP 2: CHECK IF ACTIVE (NOT STALE)**
+- **Condition**: `is_stale` is **False**.
+- **Action**:
+    - **Check Role**: If `last_action_role` is 'author' or 'other_user':
+        - **Context**: The issue is Active.
+        - **Action (ALERT CHECK)**: Look at `maintainer_alert_needed`.
+            - **IF True**: The user edited the description silently, and we haven't alerted yet.
+              -> **Action**: Call `alert_maintainer_of_edit`.
+              -> **Report**: "Analysis for Issue #[number]: ACTIVE. Silent update detected (Description Edit). Alerted maintainer."
+            - **IF False**: 
+              -> **Report**: "Analysis for Issue #[number]: ACTIVE. Last action was by user. No action."
+
+    - **Check Role**: If `last_action_role` is 'maintainer':
+      - **Proceed to STEP 3.**
+
+**STEP 3: ANALYZE MAINTAINER INTENT**
+- **Context**: The last person to act was a Maintainer.
+- **Action**: Read the text in `last_comment_text`.
+    - **Question Check**: Does the text ask a question, request clarification, ask for logs, or suggest trying a fix?
+    - **Time Check**: Is `days_since_activity` > {stale_threshold_days}?
+
+    - **DECISION**:
+        - **IF (Question == YES) AND (Time == YES)**:
+            - **Action**: Call `add_stale_label_and_comment`.
+            - **Check**: If '{REQUEST_CLARIFICATION_LABEL}' is not in `current_labels`, call `add_label_to_issue` for it.
+            - **Report**: "Analysis for Issue #[number]: STALE. Maintainer asked question [days_since_activity] days ago. Marking stale."
+        - **IF (Question == YES) BUT (Time == NO)**:
+            - **Report**: "Analysis for Issue #[number]: PENDING. Maintainer asked question, but threshold not met yet. No action."
+        - **IF (Question == NO)** (e.g., "I am working on this"):
+            - **Report**: "Analysis for Issue #[number]: ACTIVE. Maintainer gave status update (not a question). No action."

+# ADK Stale Issue Auditor Agent
+
+This directory contains an autonomous, **GraphQL-powered** agent designed to audit a GitHub repository for stale issues. It maintains repository hygiene by ensuring all open items are actionable and responsive.
+
+Unlike traditional "Stale Bots" that only look at timestamps, this agent uses a **Unified History Trace** and an **LLM (Large Language Model)** to understand the *context* of a conversation. It distinguishes between a maintainer asking a question (stale candidate) vs. a maintainer providing a status update (active).
+
+---
+
+## Core Logic & Features
+
+The agent operates as a "Repository Auditor," proactively scanning open issues using a high-efficiency decision tree.
+
+### 1. Smart State Verification (GraphQL)
+Instead of making multiple expensive API calls, the agent uses a single **GraphQL** query per issue to reconstruct the entire history of the conversation. It combines:
+*   **Comments**
+*   **Description/Body Edits** ("Ghost Edits")
+*   **Title Renames**
+*   **State Changes** (Reopens)
+
+It sorts these events chronologically to determine the **Last Active Actor**.
+
+### 2. The "Last Actor" Rule
+The agent follows a precise logic flow based on who acted last:
+
+*   **If Author/User acted last:** The issue is **ACTIVE**.
+    *   This includes comments, title changes, and *silent* description edits.
+    *   **Action:** The agent immediately removes the `stale` label.
+    *   **Silent Update Alert:** If the user edited the description but *did not* comment, the agent posts a specific alert: *"Notification: The author has updated the issue description..."* to ensure maintainers are notified (since GitHub does not trigger notifications for body edits).
+    *   **Spam Prevention:** The agent checks if it has already alerted about a specific silent edit to avoid spamming the thread.
+
+*   **If Maintainer acted last:** The issue is **POTENTIALLY STALE**.
+    *   The agent passes the text of the maintainer's last comment to the LLM.
+
+### 3. Semantic Intent Analysis (LLM)
+If the maintainer was the last person to speak, the LLM analyzes the comment text to determine intent:
+*   **Question/Request:** "Can you provide logs?" / "Please try v2.0."
+    *   **Verdict:** **STALE** (Waiting on Author).
+    *   **Action:** If the time threshold is met, the agent adds the `stale` label. It also checks for the `request clarification` label and adds it if missing.
+*   **Status Update:** "We are working on a fix." / "Added to backlog."
+    *   **Verdict:** **ACTIVE** (Waiting on Maintainer).
+    *   **Action:** No action taken. The issue remains open without stale labels.
+
+### 4. Lifecycle Management
+*   **Marking Stale:** After `STALE_HOURS_THRESHOLD` (default: 7 days) of inactivity following a maintainer's question.
+*   **Closing:** After `CLOSE_HOURS_AFTER_STALE_THRESHOLD` (default: 7 days) of continued inactivity while marked stale.
+
+---
+
+## Performance & Safety
+
+*   **GraphQL Optimized:** Fetches comments, edits, labels, and timeline events in a single network request to minimize latency and API quota usage.
+*   **Search API Filtering:** Uses the GitHub Search API to pre-filter issues created recently, ensuring the bot doesn't waste cycles analyzing brand-new issues.
+*   **Rate Limit Aware:** Includes intelligent sleeping and retry logic (exponential backoff) to handle GitHub API rate limits (HTTP 429) gracefully.
+*   **Execution Metrics:** Logs the time taken and API calls consumed for every issue processed.
+
+---
+
+## Configuration
+
+The agent is configured via environment variables, typically set as secrets in GitHub Actions.
+
+### Required Secrets
+
+| Secret Name | Description |
+| :--- | :--- |
+| `GITHUB_TOKEN` | A GitHub Personal Access Token (PAT) or Service Account Token with `repo` scope. |
+| `GOOGLE_API_KEY` | An API key for the Google AI (Gemini) model used for reasoning. |
+
+### Optional Configuration
+
+These variables control the timing thresholds and model selection.
+
+| Variable Name | Description | Default |
+| :--- | :--- | :--- |
+| `STALE_HOURS_THRESHOLD` | Hours of inactivity after a maintainer's question before marking as `stale`. | `168` (7 days) |
+| `CLOSE_HOURS_AFTER_STALE_THRESHOLD` | Hours after being marked `stale` before the issue is closed. | `168` (7 days) |
+| `LLM_MODEL_NAME`| The specific Gemini model version to use. | `gemini-2.5-flash` |
+| `OWNER` | Repository owner (auto-detected in Actions). | (Environment dependent) |
+| `REPO` | Repository name (auto-detected in Actions). | (Environment dependent) |
+
+---
+
+## Deployment
+
+To deploy this agent, a GitHub Actions workflow file (`.github/workflows/stale-bot.yml`) is recommended.
+
+### Directory Structure Note
+Because this agent resides within the `adk-python` package structure, the workflow must ensure the script is executed correctly to handle imports.
