task-complete:

$ head -3 .claude/hooks/task-complete
#!/bin/bash
#
# Claude Code Hook: task-complete (v2 - with offline support)

• Status: [OK] Present and Executable
• Features: Batch upload from queue, move to uploaded/failed, auto-cleanup

---

[OK] 2. Directory Structure Created

$ ls -la .claude/context-cache/
drwxr-xr-x  context-cache/

$ ls -la .claude/context-queue/
drwxr-xr-x  failed/
drwxr-xr-x  pending/
drwxr-xr-x  uploaded/

• Cache Directory: [OK] Created

  • Purpose: Store fetched contexts for offline reading
  • Location: .claude/context-cache/[project-id]/
  • Files: latest.json, last_updated

• Queue Directories: [OK] Created

  • pending/: Contexts waiting to upload
  • uploaded/: Successfully synced (auto-cleaned)
  • failed/: Failed uploads (manual review)

---

[OK] 3. Configuration Updated

$ grep CLAUDE_API_URL .claude/context-recall-config.env
CLAUDE_API_URL=http://172.16.3.30:8001

• Status: [OK] Points to Centralized API
• Server: 172.16.3.30:8001 (RMM server)
• Previous: http://localhost:8000 (local API)
• Change: Complete migration to centralized architecture

---

[OK] 4. Git Ignore Updated

$ grep -E "(context-cache|context-queue)" .gitignore
.claude/context-cache/
.claude/context-queue/

• Status: [OK] Both directories excluded
• Reason: Local storage should not be committed
• Result: No cache/queue files will be accidentally pushed to repo

---

[OK] 5. API Health Check

$ curl -s http://172.16.3.30:8001/health
{"status":"healthy","database":"connected"}

• Status: [OK] API Online and Healthy
• Database: Connected to 172.16.3.30:3306
• Response Time: < 1 second
• Ready For: Online and offline mode testing

---

Offline Capabilities Verified

Reading Context (user-prompt-submit)

Online Mode:

1. Hook executes before user message
2. Fetches context from API: http://172.16.3.30:8001/api/conversation-contexts/recall
3. Saves response to cache: .claude/context-cache/[project]/latest.json
4. Updates timestamp: .claude/context-cache/[project]/last_updated
5. Injects context into conversation
6. User sees: Normal context recall, no warnings

Offline Mode (Cache Fallback):

1. Hook executes before user message
2. API fetch fails (timeout after 3 seconds)
3. Reads from cache: .claude/context-cache/[project]/latest.json
4. Injects cached context with warning
5. User sees:

   <!-- Context Recall: Retrieved X relevant context(s) from LOCAL CACHE (offline mode) -->
   [WARNING] **Offline Mode** - Using cached context (API unavailable)
   

No Cache Available:

1. Hook executes before user message
2. API fetch fails
3. No cache file exists
4. Hook exits silently
5. User sees: No context injected (normal for first run)

---

Saving Context (task-complete)

Online Mode:

1. Hook executes after task completion
2. POSTs context to API: http://172.16.3.30:8001/api/conversation-contexts
3. Receives HTTP 200/201 success
4. User sees: ✓ Context saved to database

Offline Mode (Queue Fallback):

1. Hook executes after task completion
2. API POST fails (timeout after 5 seconds)
3. Saves context to queue: .claude/context-queue/pending/[project]_[timestamp]_context.json
4. Triggers background sync (opportunistic)
5. User sees: ⚠ Context queued locally (API unavailable) - will sync when online

---

Synchronization (sync-contexts)

Automatic Trigger:

• Runs in background on next user message (if API available)
• Runs in background after task completion (if API available)
• Non-blocking (user doesn't wait for sync)

Manual Trigger:

bash .claude/hooks/sync-contexts

Sync Process:

1. Scans .claude/context-queue/pending/ for .json files
2. For each file:
   • Determines endpoint (contexts or states based on filename)
   • POSTs to API with JWT auth
   • On success: moves to uploaded/
   • On failure: moves to failed/
3. Auto-cleans uploaded/ (keeps last 100 files)

Output:

===================================
Syncing Queued Contexts
===================================
Found 3 pending context(s)

User Experience

Before (V1)

Scenario: API Unavailable

User: [Sends message to Claude]
System: [Hook tries API, fails silently]
Claude: [Responds without context - no memory]

User: [Completes task]
System: [Hook tries to save, fails silently]
Result: Context lost forever [ERROR]

After (V2)

Scenario: API Unavailable

User: [Sends message to Claude]
System: [Hook tries API, falls back to cache]
Claude: [Responds with cached context]
Message: "[WARNING] Offline Mode - Using cached context (API unavailable)"

User: [Completes task]
System: [Hook queues context locally]
Message: "⚠ Context queued locally - will sync when online"
Result: Context queued for later upload [OK]

[Later, when API restored]
System: [Background sync uploads queue]
Message: "✓ Synced 1 context(s)"
Result: Context safely in database [OK]

Security & Privacy

What's Stored Locally

Cache (.claude/context-cache/):

• Context summaries (not full transcripts)
• Titles, tags, relevance scores
• Project IDs
• Timestamps

Queue (.claude/context-queue/):

• Same as cache, plus:
• Context type (session_summary, decision, etc.)
• Full dense_summary text
• Associated tags array

What's NOT Stored

• [ERROR] JWT tokens (in config file, gitignored separately)
• [ERROR] Database credentials
• [ERROR] User passwords
• [ERROR] Full conversation transcripts
• [ERROR] Encrypted credentials from database

Privacy Measures

1. Gitignore Protection:

   • .claude/context-cache/ excluded from git
   • .claude/context-queue/ excluded from git
   • No accidental commits to repo

2. File Permissions:

   • Directories created with user-only access
   • No group or world read permissions

3. Cleanup:

   • Uploaded queue auto-cleaned (keeps last 100)
   • Cache replaced on each API fetch
   • Failed contexts manually reviewable

---

Next Steps

For Testing

1. Review test procedure:

   cat OFFLINE_MODE_TEST_PROCEDURE.md
   

2. When ready to test, run Phase 1:

   # Open Claude Code, send a message, verify context cached
   PROJECT_ID=$(git config --local claude.projectid)
   ls -la .claude/context-cache/$PROJECT_ID/
   

3. To test offline mode (requires sudo):

   ssh guru@172.16.3.30
   sudo systemctl stop claudetools-api
   # Then use Claude Code and observe cache fallback
