Detect overlapping or closely related projects and merge them into a single consolidated project note.
CRITICAL RULES
- Never merge automatically — always present candidates and get user approval
- Never delete source projects until merged project is verified
- Merged project inherits the highest status of its sources (seed < idea < active < writing < finished)
- All paper links from source projects must be preserved in merged project
- All MOC links from source projects must be preserved in merged project
- Bidirectional links must be updated: papers that linked to old projects must link to merged project
- Vault index must be updated after merge
WORKFLOW
1. Choose mode
Ask user:
- Scan for candidates? (analyze all projects for overlap)
- Merge specific projects? (user names 2-3 projects to merge)
2a. Scan mode — Identify merge candidates
Read vault index to get all projects and their descriptions.
For each project pair, assess overlap signals:
- Similar research questions or hypotheses
- Shared relevant papers (≥2 papers in common)
- Overlapping MOC links
- Complementary seed ideas (one project's approach is another's variant)
- Same phenomenon studied from slightly different angles
Score overlap:
- 🔴 High overlap (likely should merge): same core question, ≥3 shared papers, nearly identical hypotheses
- 🟡 Moderate overlap (consider merging): related questions, 2 shared papers, one could be a variant of the other
- 🟢 Low overlap (keep separate): distinct questions, ≤1 shared paper, different mechanisms
Present candidates grouped by overlap score. For each candidate pair/group:
- List the projects
- Explain WHY they overlap (shared papers, similar questions, etc.)
- Suggest which project should be the "primary" (the more developed one)
- Suggest a merged title if current titles are too narrow
Get user approval before proceeding to merge.
2b. Direct merge mode — User specifies projects
- Read all specified project files in full
- Confirm overlap is real
- Ask user which should be primary (or suggest based on development level)
- Proceed to merge
3. Execute merge
Create merged project:
- Use the primary project as base
- Integrate content from secondary project(s) section by section:
| Section | Merge strategy |
|---|---|
| Current Focus | Keep primary's; note secondary's angle if distinct |
| Seed Idea | Combine triggers from all sources |
| Current Working Idea | Synthesize into broader framing |
| Research Question | Merge into unified question; keep sub-questions if distinct |
| Hypothesis / Claim | Keep primary; add secondary as alternative hypothesis if different |
| Context & Motivation | Union of all motivations |
| Possible Approaches | Union of all approaches (deduplicate) |
| Research Ideas & Variants | Secondary project's main direction becomes a variant |
| Related Work | Union (deduplicate) |
| Relationship to Prior Work | Union (deduplicate) |
| Possible Experiments | Union (deduplicate) |
| Open Questions & Risks | Union (deduplicate) |
| Next Actions | Union; remove completed/redundant |
| Relevant Papers | Union of ALL paper links (no paper lost) |
Decide on merged title:
- If primary title is broad enough → keep it
- If both titles are narrow → create new title capturing combined scope
- Title must be concise and descriptive
Set merged status:
- Use highest status among source projects
- If any source is
activeor higher → merged project inherits that status
4. Update all references
Papers linking to absorbed projects:
- Find all papers in
Reading/that link to secondary (absorbed) project(s) - Replace
[[Old Project Name]]with[[Merged Project Name]]in their "Linked Research Projects" section
MOCs containing absorbed projects:
- Find MOCs listing secondary project(s)
- Replace with merged project link (avoid duplicates if primary already listed)
Projects referencing absorbed projects:
- Check if any other projects reference the absorbed ones in Related Work
- Update those references
5. Remove absorbed projects
Only after verification:
- Confirm merged project file exists and is complete
- Confirm all paper links updated
- Confirm all MOC links updated
- Confirm no remaining references to old project names
Then delete secondary (absorbed) project files.
6. Update vault index
- Run update_vault_index logic or notify user to run
/update_vault_index
TOKEN EFFICIENCY
Optimizations:
- In scan mode: read only vault index + project frontmatter + Relevant Papers sections first
- Only read full project files for confirmed merge candidates
- Use grep to find references to absorbed project names across vault
- Batch reference updates per file
Avoid:
- Reading all project files in full during scan phase
- Reading paper files unless needed for reference updates
- Multiple passes over same files
OUTPUT RULES
- Scan results: table of candidate pairs with overlap score + rationale
- Merge summary: before/after comparison (projects consolidated, papers preserved, links updated)
- Bullets only, no prose
- Confirm paper count preserved: "X papers linked before → X papers linked after"
SELF-CHECK
✅ Did I get user approval before merging? ✅ Are ALL paper links from source projects preserved in merged project? ✅ Are ALL MOC links preserved? ✅ Did I update paper notes that linked to absorbed projects? ✅ Did I update MOCs that listed absorbed projects? ✅ Did I check for references to absorbed projects in other project files? ✅ Is the merged project status correct (highest of sources)? ✅ Did I delete absorbed project files only after full verification? ✅ Is the vault index updated or user notified to update? ✅ No orphan references remain to deleted project names?
