[Writers] Define use cases for must-have abilities

[pluginslab]

Goal

For each of the 10 must-have abilities, define the use case spec that PHP and JS developers will build from.

What to Define (per ability)

• Natural language triggers: 5-10 phrases a user might say (these become keywords)
• Expected behavior: What the AI should do, step by step
• Response format: What the user should see (example output with markdown formatting)
• Read-only or destructive?: Does it modify data? Does it need confirmation?
• Edge cases: What if there are no results? What if there's an error?

Abilities Needing Use Cases

• theme-list
• user-list
• update-check
• disk-usage
• post-list
• comment-stats
• security-scan
• error-log-search
• opcode-cache-status
• backup-check

How to Submit

Add your use case as a comment on the relevant ability issue, or submit them all here as a single comment.

Context

• See the ability issues for implementation details
• See CLOUDFEST_HACKATHON.md for the Writer role definition
• Look at existing abilities in src/extensions/abilities/ for examples of keywords and summarize functions

Overview

Complete use case specifications for all 10 required WordPress AI abilities. Each specification includes:

1. Natural Language Triggers (5-10 phrases users might say → keywords)
2. Expected Behavior (what the AI should do, step by step)
3. Response Format (example output with markdown formatting)
4. Read-only or Destructive? (data modification, confirmation needs)
5. Edge Cases (special situations handling)

---

1. theme-list - List Installed Themes

Natural Language Triggers

"List themes", "Show installed themes", "What themes do I have?", "Display all themes", "Theme overview"

Expected Behavior

1. Query WordPress database for installed themes
2. Retrieve theme info (name, version, author, description, active status)
3. Check for available updates
4. Format with active theme highlighted, others categorized
5. Present with update status and recommendations

Response Format (Example)

# Theme List Results
**Found:** 5 installed themes (1 active, 2 have updates)

## Active Theme
- **Twenty Twenty-Four** v1.0 (WordPress Team)

## Other Themes
1. **Twenty Twenty-Three** v1.3 → Update available (1.4)
2. **Astra** v4.1.6 → Update available (4.2.0)
3. **OceanWP** v3.4.5 → Up to date
4. **GeneratePress** v3.3.0 → Up to date

## Recommendations
- Update Twenty Twenty-Three for security fixes
- Review inactive themes for removal

Read-only or Destructive?

Read-only - No data modification, no confirmation needed
Permissions: switch_themes capability

Key Edge Cases

• No themes found → Suggest theme installation
• Permission issues → Show only authorized information
• Many themes → Paginate or summarize

---

2. user-list - List WordPress Users

Natural Language Triggers

"List users", "Show all users", "Who has access?", "User management", "Site members"

Expected Behavior

1. Query users from WordPress database
2. Group by role (admin, editor, author, contributor, subscriber)
3. Include username, email, role, registration date, last login
4. Check for security patterns (failed logins, inactive users)

Read-only or Destructive?

Read-only - Only searches logs, doesn't modify
Permissions: manage_options + log file read access

Key Edge Cases

• No logs found → Enable debugging instructions
• Very large logs → Efficient parsing, sampling
• Sensitive data in logs → Masking/obfuscation

- **Memory Usage:** 200.7/256 MB (78.4%) ⚠️ Approaching 80%
- **Cached Scripts:** 1,847 files (WordPress: 60.8%, Plugins: 29.4%, Themes: 9.8%)

## Configuration Assessment
✅ **Good:** Enabled, 256MB allocation, 10,000 file limit  
⚠️ **Suboptimal:** validate_timestamps=1 (disable in production)  
❌ **Missing:** Preloading not configured (PHP 7.4+ feature)

## Recommendations
1. **Increase interned strings buffer** from 16MB → 32MB (3-5% performance)
2. **Disable timestamp validation** in production (8-12% performance)
3. **Implement OPcache preloading** (15-20% faster first loads)
4. **Monitor memory** - consider 384MB if consistently >80%

Read-only or Destructive?

Read-only - Only checks status, doesn't modify cache
Permissions: Ability to call opcache_get_status() and opcache_get_configuration()

Key Edge Cases

• OPcache not installed → Installation instructions
• Limited function access → Alternative methods
• Development vs production → Different recommendations

✅ **Dual strategy** (scheduled + real-time)  
✅ **Off-site storage** (geographic redundancy)  
✅ **Recent backups** (all <48 hours)  
⚠️ **Local storage** 15.3 GB (consider cleanup)  
⚠️ **Restore test overdue** (45 days ago - should be monthly)

## 3-2-1 Rule Compliance
✅ **3 copies** (local, Google Drive, VaultPress cloud)  
✅ **2 media types** (cloud + local disk)  
✅ **1 off-site** (Google Drive different region)

Read-only or Destructive?
