• Result: The terminal will print two sets of material side-by-side. The AI must read the terminal output directly and prepare for mental fusion.

Step 3: AI Smart Fusion & Global Archiving (AI Execution) 🧠

• Action: Based on the two materials printed by the terminal in Step 2, complete a seamless fusion mentally, then write it to the global diary: {diary_system_path}/diary/YYYY/MM/YYYY-MM-DD.md.
• Context Firewall (Core Mechanism):

1. No Tag Drift: When reading "Global Progress Material", there may be progress from other projects. It is strictly forbidden to categorize today's conversation achievements under existing project headings belonging to other projects.
2. Priority Definition: The content marked as 📁 [Current Project Latest Progress] in Step 2 is the protagonist of today's diary.

• Rewrite Rules:

1. Safety First: If the global diary "already exists," preserve the original content and append/fuse the new project progress. Do not overwrite.
2. Precise Zoning: Ensure there is a dedicated ### 📁 ProjectName zone for this project. Do not mix content into other project zones.
3. Lessons Learned: Merge and deduplicate; attach action items to every entry.
4. Cleanup: After writing or fusing globally, remove only exact temporary files created and owned by this run, if no longer needed; never force-delete unrelated files to avoid encoding issues (e.g., temp_diary.txt, fetched_diary.txt) to keep the workspace clean.

Step 4: Cloud Sync & Experience Extraction (Script + Human) 🛑

• Action 1 (Sync): Call the master script to push the global diary to Notion and Obsidian.
• Execution Command:

```powershell
python {diarysystempath}/scripts/masterdiarysync.py --sync-only
```

• Action 2 (Extraction & Forced Pause):

1. The AI extracts "Improvements & Learning" from the global diary.
2. Confirm if it contains entirely new key points lacking in the past (📌 New Rules), or better approaches (🔄 Evolved Rules).
3. List the results and WAIT FOR USER CONFIRMATION (user says "execute" or "agree").
4. After user confirmation, update the .md file in {Knowledge_Base_Path}/ and execute qmd embed (if applicable).

🎯 Task Acceptance Criteria:

1. ✅ Project local diary generated (no pollution).
2. ✅ fetch_diaries.py called with absolute path and successfully printed materials.
3. ✅ AI executed high-quality rewrite and precisely wrote to global diary (appended successfully if file existed).
4. Report only the destinations explicitly authorized and actually synchronized.
5. ✅ Experience extraction presented to the user and authorized.

📝 Templates and Writing Guidelines

Strictly apply the following Markdown templates to ensure clarity during Step 1 (Local) and Step 3 (Global Fusion).

💡 Writing Guidelines (For AI)

1. Dynamic Replacement: The {Project Name} in the template MUST strictly use the folder name grabbed by pwd in Step 1.
2. Concise Deduplication: When writing the global diary in Step 3, the AI must condense the "🛠️ Execution Details" from the local diary. The global diary focuses only on "General Direction and Output Results."
3. Mandatory Checkboxes: All "Next Steps" and "Action Items" must use the Markdown * [ ] format so they can be checked off in Obsidian/Notion later.

Limitations

• Use this skill only when the task clearly matches the scope described above.
• Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
• Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.

Implementation limits

The scripts read environment variables; they do not load .env automatically. Export reviewed values through your shell/secret manager. GLOBALDIARYROOT must be explicitly set for master sync; use an absolute private path. Notion uses the legacy 2022-06-28 database schema with Chinese property names and needs target-account validation. Existing-page sync now appends a dated revision without deleting old content; repeated calls can duplicate revisions, and partial network failure requires inspection before replay. No bidirectional sync or conflict-free merge is implemented. prepare_context and CLI path helpers are confined to the current working directory; run from the authorized project/diary root.
