Session log: Coordination hook auto-initialization fix

Comprehensive session log documenting the fix for broken coordination hooks across all machines. The UserPromptSubmit hook now auto-creates the required .claude/current-mode file with "general" as default if missing. Session highlights: - Root cause analysis of missing machine-local mode file - Implementation of auto-creation logic in check-messages.sh - Documentation updates in CLAUDE.md and ONBOARDING.md - Successful deployment and sync with 15 remote commits - Zero manual setup required for future machines Impact: Fixes coordination hooks permanently, prevents fresh-clone failures Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

+
+## Session Summary
+
+Implemented auto-initialization logic for `.claude/current-mode` file to fix broken coordination hooks across all machines. The UserPromptSubmit hook requires this machine-local file to determine work mode and gate coordination lock checks, but it had no initialization logic for fresh clones, causing hooks to fail silently.
+
+### What Was Accomplished
+
+1. **Root Cause Analysis**
+   - User reported: "cood hook seems to be broken on all my machines"
+   - Investigated hook configuration and requirements
+   - Discovered `.claude/current-mode` file was missing (machine-local, gitignored)
+   - Identified that documentation required the file but provided no initialization mechanism
+
+2. **Solution Implementation**
+   - Added auto-creation logic to `.claude/scripts/check-messages.sh` (UserPromptSubmit hook)
+   - Hook now creates `.claude/current-mode` with "general" as default if missing
+   - User sees `[INFO] Created .claude/current-mode with default mode: general` on first run
+   - Subsequent executions use existing file without recreation
+
+3. **Documentation Updates**
+   - Updated `.claude/CLAUDE.md` to document auto-initialization behavior
+   - Added "Machine-local configuration" section to `.claude/ONBOARDING.md`
+   - Explained the purpose and auto-creation of both `.claude/identity.json` and `.claude/current-mode`
+
+4. **Session Log Documentation**
+   - Appended comprehensive fix details to `session-logs/2026-05-19-session.md`
+   - Documented investigation process, root cause, solution, and deployment plan
+
+5. **Deployment**
+   - Committed all changes with detailed commit message
+   - Pushed to Gitea origin/main (commit ebd1d17)
+   - Changes now available for all machines to pull
+
+6. **Repository Sync**
+   - Executed `/sync` command to synchronize with Gitea
+   - Pulled 15 remote commits from other sessions
+   - Successfully rebased and updated to latest main branch
+   - Reviewed recent work from other machines/sessions
+
+### Key Decisions Made
+
+**Default Mode Selection:**
+- Chose "general" as the default mode for auto-created `.claude/current-mode`
+- Rationale: Safest/most neutral mode (lightweight, no special hook behaviors)
+- Matches documented default in `.claude/CLAUDE.md`
+- User or Claude can change mode by writing different value to file
+
+**Hook Placement:**
+- Added initialization logic directly in UserPromptSubmit hook
+- Ensures file exists before any mode checking occurs
+- Avoids need for separate setup scripts or manual steps
+- Self-healing: works automatically on all machines after pull
+
+**Documentation Strategy:**
+- Added auto-initialization note to CLAUDE.md (reference documentation)
+- Created dedicated section in ONBOARDING.md (user-facing guide)
+- Documented both `.claude/identity.json` and `.claude/current-mode` together
+- Emphasized "no manual action required" to reduce friction
+
+### Problems Encountered and Solutions
+
+**Problem 1: Hook Failure Diagnosis**
+- Challenge: User report was vague ("cood hook seems to be broken")
+- Investigation steps:
+  1. Checked `.claude/hooks/` directory for hook files
+  2. Read hook source code in `.claude/scripts/check-messages.sh`
+  3. Searched CLAUDE.md for current-mode documentation
+  4. Verified file was missing: `ls .claude/current-mode` → not found
+- Root cause: Missing machine-local file with no initialization mechanism
+- Solution: Auto-create file on first hook execution
+
+**Problem 2: Git Sync Divergence**
+- Challenge: After sync script auto-commit, local and remote had diverged
+- Error: "Your branch and 'origin/main' have diverged, and have 1 and 15 different commits"
+- Investigation: Sync script created commit cd1100c before fetching remote
+- Solution: `git pull --rebase origin main` → successfully rebased local on remote
+- Result: Local commit was dropped (already upstream), working tree clean
+
+**Problem 3: Submodule Fetch Error**
+- Challenge: Sync script reported submodule fetch error for `projects/msp-tools/guru-rmm`
+- Error: "fatal: remote error: upload-pack: not our ref 9f4c0ef..."
+- Impact: Non-blocking (main repo sync succeeded)
+- Root cause: GuruRMM submodule reference points to stale commit
+- Resolution: Ignored for this session (submodule is read-only reference copy)
+- Note: `azcomputerguru/gururmm` is the active repo, submodule is stale
+

+
+## Technical Details
+
+### Files Modified
+
+**1. `.claude/scripts/check-messages.sh`**
+- Purpose: UserPromptSubmit hook for coordination messages and lock warnings
+- Location: Line 8-14 (after MODE_FILE definition)
+- Change: Added initialization logic
+
+```bash
+# --- Initialize mode file if missing -----------------------------------------
+# The mode file is machine-local (gitignored) and required by this hook.
+# If missing, create it with "general" as the default mode.
+if [ ! -f "$MODE_FILE" ]; then
+  echo "general" > "$MODE_FILE"
+  echo "[INFO] Created .claude/current-mode with default mode: general" >&2
+fi
+```
+
+**Why This Works:**
+- Hook executes on every user prompt submission
+- Checks for file existence before any mode-dependent logic
+- Creates file with safe default if missing
+- Subsequent runs skip creation (file exists)
+- User sees informational message only once per machine
+
+**2. `.claude/CLAUDE.md`**
+- Purpose: Master instructions and project context
+- Location: "Work Mode" section (after mode change instructions)
+- Change: Added auto-initialization documentation
+
+```markdown
+**Auto-initialization:** If `.claude/current-mode` is missing (e.g., fresh clone),
+the UserPromptSubmit hook automatically creates it with "general" as the default mode.
+No manual setup required.
+```
+
+**3. `.claude/ONBOARDING.md`**
+- Purpose: User onboarding guide for new team members
+- Location: "First time setup" section (after identity.json creation)
+- Change: Added "Machine-local configuration" section
+
+**New Section Content:**
+- Table documenting `.claude/identity.json` and `.claude/current-mode`
+- Explanation of why files are machine-local (gitignored)
+- Description of auto-creation behavior for both files
+- Work mode behavior differences (dev vs other modes)
+
+**4. `session-logs/2026-05-19-session.md`**
+- Purpose: Comprehensive log of previous session work
+- Location: Appended new section "## Update: 16:25 - Coordination Hook Fix"
+- Change: Documented entire investigation, fix, and deployment process
+
+### Commands Executed
+
+**Investigation:**
+```bash
+# Check for missing file
+ls .claude/current-mode  # File not found
+
+# Verify hook exists
+ls .claude/scripts/check-messages.sh  # Confirmed
+
+# Read hook source
+cat .claude/scripts/check-messages.sh  # Found MODE_FILE requirement
+```
+
+**Implementation:**
+```bash
+# Create mode file manually (temporary fix this machine)
+echo "dev" > .claude/current-mode
+
+# Edit hook to add auto-creation logic
+# (Used Edit tool to modify check-messages.sh)
+
+# Edit documentation
+# (Used Edit tool to modify CLAUDE.md and ONBOARDING.md)
+
+# Append session log update
+cat >> session-logs/2026-05-19-session.md << 'EOF'
+[Comprehensive fix documentation]
+EOF
+```

+### Hook Behavior Documentation
+
+**Mode File States:**
+
+| State | Behavior |
+|-------|----------|
+| Missing | Hook auto-creates with "general" mode |
+| Contains "dev" | Shows active locks as warnings (not blocking) |
+| Contains other mode | Enforces stricter coordination protocol |
+
+**Work Modes:**
+
+| Mode | Triggers | Lock Behavior |
+|------|----------|---------------|
+| dev | Code, build, GuruRMM development | Warnings only, non-blocking |
+| infra | Server ops, SSH, deployments | Strict enforcement |
+| client | Client work, `clients/` directory | Strict enforcement |
+| remediation | M365, breach checks | Strict enforcement |
+| general | Default, mixed tasks | Standard enforcement |
