Inbox Processing & Large-Scale Organization

Overview

Process large Things3 inboxes (100+ items) efficiently through batch analysis, confidence-based automation, and intelligent user interaction.

CRITICAL: Before using this skill:

• Load things3-productivity skill for MCP tool patterns
• Read private-prefs/personal-taxonomy.json for organizational context
• Create temp/inbox-processing/ folder for session state

When to use: Inbox has 100+ items requiring organization.

Personal Organization Integration

Claude uses LLM-driven analysis with semantic understanding from personal-taxonomy.json:

• Work identification: Tags (e.g., "AMPL") and areas (e.g., "Amplitude")
• Priority system: 1-9 scale, 7+ for high priority
• Project patterns: Existing projects and typical content
• Semantic matching: Based on meaning, not just keywords

Core Workflow: 14-Step Process

Phase 1: Initialize & Analyze (Steps 1-3)

Step 1: Setup - Create temp/inbox-processing/ with:

session.md                    # Batch progress, statistics
match_results.json            # Decisions with confidence scores
pending_decisions.json        # Items awaiting approval
high_confidence_actions.json  # Auto-apply candidates (≥90%)
reference_items.json          # Detected reference notes
execution_log.md              # Complete action history

Step 2: Load Inbox Batch - First batch: 50 items, subsequent: 50-100 items

read_tasks(when="inbox", limit=50, include_notes=True)

Step 3: Load System Inventory - Cache once per session

list_areas()    # All areas with IDs and tags
list_projects() # All projects with metadata
list_tags()     # All tags including hierarchy

Phase 2: Categorize & Match (Steps 4-6)

Step 4: Categorize Items - Use semantic understanding:

• Actionable tasks: Clear next actions, specific outcomes
• Reference items: Notes, ideas, meeting summaries
• Project candidates: Multiple related tasks suggesting new project

Step 5: Match to Existing Structure - LLM-driven matching:

• Analyze title and notes semantically
• Consider existing areas, projects, tags
• Apply personal taxonomy patterns
• Generate confidence score (0-100%)

Step 6: Categorize by Confidence

• High (90-100%): Auto-apply with batch approval
• Medium (70-89%): Ask user in batches
• Low (<70%): Keep in inbox or ask individually

Phase 3: User Interaction (Steps 7-9)

Step 7: High-Confidence Batch Approval

## High-Confidence Matches (Batch 1: 35 items)

### Area: Amplitude (25 items, 90-100% confidence)
**Direct area references:**
- "Amplitude: Fix login bug" (100%) - Explicit area mention
- "Dashboard review for AMPL" (95%) - Work tag + clear context

**Action Plan:**
1. Set area="Amplitude" for 25 items
2. Add tags=["AMPL"] where missing (15 items)
3. Move to Today (10 high-priority items)

Approve? [Yes/No/Review individually]

Step 8: Ambiguous Matches - Batched by suggested area/project

## Ambiguous Matches (10 items, 70-85%)

1. "Design review notes" (85%) → area="Amplitude"?
   [Approve / Different area / Keep in Inbox]

Quick response: "1 Approve, 2 Different area: Personal, ..."

Step 9: Reference Items - Present individually

## Reference Item 1 of 5

**Item:** [Empty title]
**Notes:** "Customer success meeting - Q4 roadmap..."

**Options:**
1. **Migrate to Notion** (Recommended)
2. **Create project "Q4 Roadmap"**
3. **Convert to task** with title
4. **Delete**

Your choice: [1/2/3/4]

Phase 4: Execute (Steps 10-12)

Step 10: Batch Execute - Use MCP tools efficiently

move_tasks(task_uuids=[...], target_list="today")
add_tags(task_uuids=[...], tags=["AMPL"])
edit_task(task_uuid="...", area="Amplitude")
migrate_inbox_to_notion(block_id="...")
create_project(name="Q4 Roadmap", area="Amplitude")

Step 11: Track Progress - Update session.md incrementally

## Progress
- Total: 446 | Processed: 100 | Remaining: 346

## Statistics
- High confidence: 70 (70%)
- Auto-applied: 65 (93% of high-confidence)

## Patterns Learned
- "Dashboard" + AMPL → area="Amplitude" (98% accuracy)

Step 12: Summary Report

## Complete Summary

**Before:** Inbox: 446 | Amplitude: 120 tasks

**Processed:** 310 organized (70%), 45 migrated (10%), 91 kept (20%)

**After:** Inbox: 91 | Amplitude: 385 tasks (+265)

**New Projects:** Q4 Roadmap (12 tasks), Team Onboarding (8 tasks)

Phase 5: Learn & Cleanup (Steps 13-14)

Step 13: Propose Taxonomy Updates - Based on patterns discovered

## Proposed Taxonomy Updates

### New Project Keywords
"On-call": ["on-call", "oncall", "incident"] (25 occurrences, 100% accuracy)
"Dashboard": ["dashboard", "metrics"] (18 occurrences, 98% accuracy)

### Common Patterns
- Empty title + meeting notes → migrate_to_notion (95% approval, 12 samples)

Approve these updates? [Yes/No/Modify]

CRITICAL: Always get user approval before updating personal-taxonomy.json.

Step 14: Cleanup - Archive or delete temp folder

mv temp/inbox-processing temp/inbox-processing-2025-11-30-archive
# Or: rm -rf temp/inbox-processing

Matching Strategy: LLM-Driven

Core Principle: Use Claude's semantic understanding, not hard-coded algorithms.

Confidence Assessment

High Confidence (90-100%)

• Explicit area/project mentions
• Strong semantic relationship to existing structure
• Consistent with taxonomy patterns

Example: "Amplitude: Fix login bug" → 100%

• Explicit area mention + work tag "AMPL" + matches existing area

Medium Confidence (70-89%)

• Reasonable but ambiguous
• Could fit multiple areas/projects

Example: "Design review notes" → 85%

• Has work tag but generic term, needs confirmation

Low Confidence (<70%)

• No clear organizational fit
• Keep in inbox or ask individually

Always Provide Reasoning

**Task:** "Dashboard analytics update"
**Confidence:** 95%
**Suggested:** area="Amplitude", project="Dashboard"
**Reasoning:**
- Work tag "AMPL" present
- "Dashboard" matches existing project
- Pattern seen 18 times with 98% accuracy

Reference Item Detection

Use semantic understanding to identify reference items:

Strong indicators:

• Empty title + substantial notes (>50 words)
• Tagged "migrate to notion"
• URL-only content
• Titles: "Note:", "Idea:", "Reference:"

Contextual analysis:

• Informational rather than actionable
• Multi-paragraph notes without clear next actions
• Meeting summaries, research findings

Four-Option Decision Tree

1. Migrate to Notion (Most Common)

• Preserve detailed notes as documentation
• Extract actionable items as separate Things3 tasks
• Best for: Meeting notes, research, planning docs

2. Create Project + Extract Tasks

• Content suggests multiple related actions
• Best for: Multi-step initiatives, campaigns

3. Convert to Single Task

• Add descriptive title to empty-title item
• Best for: Simple notes, reminders

4. Delete

• Outdated or no longer relevant

User Interaction Patterns

Minimizing Fatigue

• Auto-apply ≥90% confidence (reduces decisions by 60-70%)
• Batch similar questions together
• Provide quick response formats
• Show progress and remaining items
• Target: <20 interaction points for 400 items

Four Interaction Types

1. Batch Approval (High confidence) - Group by area/project, simple Yes/No
2. Batched Questions (Medium confidence) - Numbered list, quick format
3. Individual Questions (References) - Full preview with 4 options
4. Change Validation (Before execution) - Before/After summary

Learning & Taxonomy Updates

After each session, propose updates to personal-taxonomy.json:

What to capture:

1. New project keywords - Projects that appeared frequently with accuracy rates
2. Common matching patterns - Successful matches and user corrections
3. Reference patterns - What user consistently migrated/converted
4. Workflow preferences - Batch sizes and interaction patterns that worked

Update Format:

{
  "things3": {
    "project_keywords": {
      "On-call": ["on-call", "incident", "alert"]
    },
    "learned_patterns": [{
      "pattern": "Dashboard + AMPL tag",
      "action": "area=Amplitude, project=Dashboard",
      "accuracy": 98,
      "sample_count": 18
    }]
  }
}

Continuous Improvement

• First session: ~70% auto-apply
• Second session: ~80% auto-apply (learned patterns)
• Ongoing: Approach 85-90% auto-apply

Best Practices

Batch Sizing

• First batch: 50 items (establish patterns)
• Subsequent: 50-100 items (apply learned patterns)
• Large inboxes (500+): Consider 2-3 sessions across days

Performance

• Cache system inventory once per session
• Use batch MCP operations where possible
• Leverage LLM context window
• Take breaks after 100-150 items

Error Recovery

• All actions logged in execution_log.md
• Can undo with Things3 MCP tools
• Session state saved (resume capability)
• Ask before destructive operations

Troubleshooting

Low auto-apply rate (<50%)

• Inbox too diverse - manual review outliers
• Update taxonomy after session
• Consider lowering threshold to 85%

Processing too slow

• Reduce batch size to 25-50
• Skip reference reviews (mark for later)
• Focus on high-confidence first pass

Incorrect matches

• Review confidence reasoning
• Check taxonomy alignment
• Add corrections to learned patterns

Session interruption

• Resume from session.md
• Check execution_log.md for last action
