+# Depression-Sensitive Web Content Support (DS-WCS)
+
+This skill enables OpenCode agents to audit and rewrite web content for depression-sensitive patterns. The skill addresses emotional safety and cognitive accessibility through evidence-based content design principles.
+
+## Purpose and Clinical Boundaries
+
+This skill is a **UX and content accessibility tool**, NOT a clinical resource. It focuses on:
+
+- Reducing shame-inducing language in digital interfaces
+- Minimizing cognitive load for users with executive function differences
+- Providing clear error recovery paths
+- Supporting emotional safety through calm, professional tone
+- Improving task completion rates for users with cognitive impairments
+
+**This skill does NOT provide:**
+- Medical advice or diagnosis
+- Clinical assessment of mental health conditions
+- Therapeutic interventions
+- Treatment recommendations
+
+For mental health concerns, users should seek guidance from qualified healthcare professionals.
+
+---
+
+## When to Use This Skill
+
+Apply this skill when auditing or reviewing:
+
+- **Error messages and validation feedback** - Forms, checkout flows, login/authentication
+- **Call-to-action buttons and labels** - Signup, submit, and action buttons
+- **Empty states and onboarding flows** - New user experiences, progressive disclosure
+- **Notifications and alerts** - Warnings, confirmations, status updates
+- **Help text and tooltips** - Form guidance, contextual assistance
+- **Content for sensitive services** - Health portals, financial services, government applications, wellness platforms
+
+**Ideal for:**
+- Content design reviews
+- UX writing audits
+- Accessibility assessments (complementary to technical WCAG audits)
+- User experience improvement initiatives
+- Inclusive design implementation
+
+---
+
+## When NOT to Use This Skill
+
+Do not use this skill for:
+
+- **Medical or clinical content requests** - "Assess if this patient has depression" (clinical diagnosis)
+- **Therapy or counseling guidance** - "What should I say to someone with depression" (treatment advice)
+- **Non-UX content reviews** - Legal documents, medical records, clinical protocols
+- **Simple grammar or typo corrections** - Use general language tools instead
+- **Content already reviewed by clinical professionals** - Mental health organization guidelines
+
+---
+
+## Context for Agents
+
+Depression affects cognitive function, including:
+
+- **Working memory**: Reduced capacity to hold information across steps
+- **Executive function**: Impaired planning, decision-making, and problem-solving
+- **Attention**: Difficulty concentrating,容易被分散
+- **Processing speed**: Slower information processing and response generation
+
+These deficits mean users may:
+- Abandon tasks when faced with shame-inducing errors
+- Struggle with complex, multi-step processes
+- Forget information between steps
+- Require clear recovery paths to maintain task completion
+- Be more sensitive to tone and emotional language
+
+This skill applies evidence-based content patterns to support these users while maintaining alignment with international accessibility standards.
+

+
+## Agent Workflow Instructions
+
+### For Audit Requests
+
+When a user requests content auditing for depression-sensitive patterns, follow this workflow:
+
+1. **Scope Definition**
+   - Identify target content (files, URLs, or user-provided text)
+   - Determine content types to review (errors, CTAs, forms, notifications, etc.)
+   - Note any context-specific considerations (health, financial, sensitive services)
+
+2. **Content Analysis**
+   - Read target content files or user-provided text
+   - Apply the audit checklist from `resources/implementation-guide.md#audit-checklist`
+   - Identify patterns across these categories:
+     - Error messages (shame language, missing recovery)
+     - CTAs (generic labels, urgency)
+     - Forms (memory reliance, required field handling)
+     - Notifications (urgency markers, dismissive tone)
+     - Empty states (obligation language, shame)
+     - Onboarding (premature disclosure, unclear value)
+     - Help text (hidden, inconsistent)
+
+3. **Severity Assessment**
+   - Rate each finding: HIGH, MEDIUM, or LOW
+   - HIGH: Causes task abandonment or emotional distress
+   - MEDIUM: Increases cognitive load or friction
+   - LOW: Missed opportunity, comfort improvement
+
+4. **Findings Report Generation**
+   - Organize by severity (HIGH first)
+   - Include file path and line number references
+   - Provide specific text excerpts (before)
+   - Reference standards for each finding
+
+5. **Standards Traceability**
+   - Map each finding to relevant WCAG 2.2 success criteria
+   - Map to W3C COGA objectives
+   - Map to ISO 9241-110 principles
+   - Map to ISO/IEC 30071-1 clauses where applicable
+
+### For Rewrite Requests
+
+When a user requests content rewriting for depression-sensitive patterns:
+
+1. **Pattern Identification**
+   - Identify problematic patterns using the rewrite library
+   - Consult `resources/implementation-guide.md#rewrite-library`
+   - Determine which principles apply
+
+2. **Rewrite Application**
+   - Apply appropriate rewrite rules
+   - Reference the 12+ before/after examples for guidance
+   - Maintain original intent while improving accessibility
+
+3. **Output Generation**
+   - Present before/after comparison
+   - Include rationale for each change
+   - Map changes to specific standards
+   - Note any context-specific considerations
+
+### Output Format Template
+
+All DS-WCS skill outputs shall follow this structure:
+
+```markdown
+## Findings
+
+### HIGH Severity
+[Findings that cause task abandonment or emotional distress]
+- **File:line**: Description of issue
+  - Original: "problematic text"
+  - Standards: WCAG X.X.X, COGA Objective Y, ISO 9241-110 Clause Z
+
+### MEDIUM Severity
+[Findings that increase cognitive load or friction]
+- Same format
+
+### LOW Severity
+[Missed opportunities for improvement]
+- Same format
+
+## Recommended Rewrites
+
+### Example 1: [Category]
+**Before:**
+```
+original text
+```
+
+**After:**
+```
+rewritten text
+```
+
+**Rationale:**
+- Why this change improves accessibility
+- How it addresses the identified issue
+
+**Standards:**
+- WCAG 2.2: X.X.X (Error Identification)
+- W3C COGA: Objective N
+- ISO 9241-110: Clause M
+
+## Structure Analysis
+
+[Optional: Observations about content organization, scanability, memory load]
+
+## Standards Traceability Summary
+
+| Finding Type | WCAG 2.2 | COGA | ISO 9241-110 | ISO/IEC 30071-1 |
+|-------------|----------|------|--------------|-----------------|
+| [Category]  | X.X.X    | Obj N| Clause M     | Clause P        |

+
+## Quality Assurance
+
+When applying this skill:
+
+1. **Preserve original intent** - Rewrites must maintain the original purpose and meaning
+2. **Maintain brand voice** - Adapt tone to match organizational style while improving accessibility
+3. **Consider context** - Sensitive contexts (health, finance) may require additional consideration
+4. **Test with users** - Where possible, validate changes with users who have cognitive differences
+5. **Document decisions** - Note any context-specific rationale for audit findings
