+# Proposal: Application Validation
+
+## Why
+
+Currently, users can create and populate applications using `/new-application` and `/populate-application`, but there's no validation mechanism to ensure the application.md files are complete before generating professional documents (CV, cover letter, email).
+
+**Problems without validation:**
+- Users might try to generate documents with placeholder text like `[To be filled]` still present
+- Incomplete job information could lead to poorly targeted applications
+- No quality gate to catch missing critical information before document generation
+- Users might forget to run `/populate-application` after adding input documents
+
+**Similar to `/validate-profile`**, we need a validation command that acts as a quality gate, ensuring application.md files are ready for document generation.
+
+## What
+
+Add a `/validate-application` slash command that validates the completeness of application.md files.
+
+### Core Functionality
+
+1. **Auto-detection**: When run without parameters, detect if current directory is inside an application folder
+2. **Explicit path**: Accept optional application folder name/path as parameter
+3. **Required section validation**: Check that critical sections are filled (Organization Info, Job Info, Job Description Summary)
+4. **Placeholder detection**: Identify unfilled template placeholders like `[To be filled]`, `[...]`, bracket patterns
+5. **Population awareness**: Warn if `input/` folder is empty or application seems unpopulated
+6. **Binary pass/fail**: Clear ✅ PASSED or ❌ FAILED status (consistent with `/validate-profile`)
+7. **Actionable errors**: Show specific issues with quoted placeholder text and guidance on how to fix
+
+### Optional Sections
+
+These can remain incomplete without causing validation failure:
+- Match Strategy
+- Key Messages
+- Tone of Voice
+- Research Notes
+- Document Checklist
+
+### User Experience
+
+```bash
+# Run from inside application folder
+cd applications/pending/2025-11-02-TechCorp-Senior-Developer
+/validate-application
+
+# Or provide path from anywhere
+/validate-application 2025-11-02-TechCorp-Senior-Developer
+```
+
+**Success output:**
+```
+✅ Application Validation: PASSED
+
+Your application is complete and ready for document generation!
+
+Summary:
+- Organization: TechCorp
+- Position: Senior Developer
+- Job requirements: 12 identified
+- Match strategy: Complete
+- Input documents: 3 files analyzed
+
+You can now proceed with generating tailored CV, cover letter, and application email.
+```
+
+**Failure output:**
+```
+❌ Application Validation: FAILED
+
+Your application has incomplete sections that need attention.
+
+Issues found:
+
+## Organization Information
+- [ ] Organization Name: Contains placeholder "[To be filled]"
+
+## Job Description Summary
+- [ ] Responsibilities: No responsibilities documented
+- [ ] Required Skills: Contains placeholder "[List required skills]"
+
+## Population Status
+⚠️  Input folder appears empty. Consider:
+1. Adding job posting and related documents to input/
+2. Running /populate-application to extract information
+
+Please update application.md, then run /validate-application again.
+```
+
+## Impact
+
+### Benefits
+- **Quality gate**: Prevents generating documents with placeholder text
+- **User guidance**: Clear feedback on what's missing and how to fix it
+- **Workflow integration**: Natural step before document generation
+- **Consistency**: Matches `/validate-profile` pattern users already know
+- **Error prevention**: Catches incomplete applications early
+
+### Changes Required
+- New slash command: `/validate-application`
+- Documentation updates in `src/CLAUDE.md`
+- No changes to existing commands or templates
+
+### User Workflow Update
+```
+1. Validate profile (/validate-profile)
+2. Initialize application (/new-application)
+3. Add documents to input/ folder
+4. Populate application (/populate-application)
+5. **Validate application (/validate-application)** ← NEW
+6. Generate documents (future: CV, cover letter, email)
+```
+
+## Implementation Approach
+
+Follow the same pattern as `/validate-profile`:
+- Read application.md and parse sections
+- Check for bracket patterns: `\[([^\]]+)\]`
+- Validate required sections have real content
+- Check input/ folder exists and has files
+- Provide structured, actionable error messages
+- Use encouraging tone and clear next steps
