2. Compatibility Analysis

2.1 Hooks System - COMPATIBLE

Status: Full compatibility confirmed.

The coditect-core hook architecture (ADR-074) aligns with Claude Code's hook protocol:

Aspect	Claude Code v2.1.32	coditect-core	Compatible?
Hook types	PreToolUse, PostToolUse, UserPromptSubmit, SessionEnd	PreToolUse, PostToolUse, SessionEnd	Yes
Input format	JSON on stdin	JSON on stdin	Yes
Output format	JSON on stdout (`continue: true/false`)	JSON on stdout	Yes
Matchers	Tool name regex patterns	Regex patterns (e.g., `Bash\|Edit\|Write`)	Yes
Timeout	Configurable per hook	Set per hook (1000-10000ms)	Yes
Fail mode	Configurable	Fail-open (ADR-074)	Yes
Concurrency	Sequential per event	Sequential	Yes

Key hooks verified:

task-id-validator.py - PreToolUse on Bash/Edit/Write/Task
task-tracking-enforcer.py - PreToolUse on TodoWrite (3 enforcement levels)
task-plan-sync.py - PostToolUse on TodoWrite (bidirectional sync)
token-limit-pivot-detector.py - PreToolUse on all tools
hook_logger.py - Centralized structured JSON logging

2.2 Configuration System - COMPATIBLE

Status: Full compatibility confirmed.

coditect-core's setup script (CODITECT-CORE-INITIAL-SETUP.py) correctly:

Deep-merges hooks into existing ~/.claude/settings.json
Preserves user-defined hooks (no overwriting)
Deduplicates hook commands before injection
Configures statusline via statusLine.command key
Sets MCP servers via mcpServers key

2.3 MCP Server Integration - COMPATIBLE

Status: Compatible. No issues found.

Feature	Support
stdio transport	Yes - coditect-skills server uses Python stdio
HTTP transport	Yes - supported for future use
Auto-discovery	Yes - `enableAllProjectMcpServers: true`
`.mcp.json`	Yes - project-level MCP config supported
Environment vars	Yes - `${workspaceFolder}` expansion works

2.4 Skills & Commands - COMPATIBLE

Status: Full compatibility. Flat structure requirement met.

Skills at skills/*/SKILL.md (no nesting) - compliant with Claude Code standard
Commands at commands/*.md - auto-discovered by Claude Code
CLAUDE.md hierarchy correctly loaded (global > project > submodule)

2.5 Statusline - COMPATIBLE

Status: Working. 7 sections, configurable via JSON toggle.

The statusline-command.sh (489 lines) correctly integrates:

Git status with lock-aware operations (300ms timeout)
Session detection with context % monitoring
Auto-preservation trigger at configurable threshold
Model-specific color coding

3. Non-Blocking Compatibility Concerns

3.1 Task ID Format Conflict (Low Risk)

Issue: The /project-new command generates task IDs in E001-T001 format, which conflicts with the track nomenclature A.9.1.3 enforced by ADR-054 and task-id-validator.py.

Impact: Tasks created via /project-new may trigger validation warnings.

Mitigation: Use track nomenclature manually in TodoWrite. The task-id-validator.py currently set to warn level (non-blocking).

Recommendation: Add format normalization adapter in task-plan-sync.py to convert between formats.

3.2 context.db Migration Incomplete (Low Risk)

Issue: ADR-118 deprecated context.db in favor of org.db + sessions.db, but some legacy code paths may still reference it.

Impact: No runtime impact - hooks already use sessions.db via get_sessions_db_path().

Recommendation: Complete the migration audit and remove remaining context.db references.

3.3 No Claude Code Version Pinning (Low Risk)

Issue: CODITECT-CORE-INITIAL-SETUP.py validates Python (3.10+), Git (2.30+), and Node (18+) versions but does not check claude --version.

Impact: Future Claude Code versions could introduce breaking changes to hook protocol.

Recommendation: Add version check: claude --version with minimum version constraint.

3.4 SQLite Concurrent Write Contention (Low Risk)

Issue: Multiple hooks writing to sessions.db concurrently (e.g., task-tracking-enforcer.py and task-plan-sync.py both write during TodoWrite events) without WAL mode enabled.

Impact: Potential SQLITE_BUSY errors under high hook load. Mitigated by sequential hook execution within each event type.

Recommendation: Enable WAL mode (PRAGMA journal_mode=WAL) in database initialization.

4. Suggested Enhancements

Priority 1: Critical Improvements

E-001: Claude Code Version Pinning

What: Add claude --version check to CODITECT-CORE-INITIAL-SETUP.py Why: Prevent silent incompatibilities with future Claude Code releases Where: scripts/CODITECT-CORE-INITIAL-SETUP.py Step 3 (Claude Code config) Effort: Small (10 lines)

MIN_CLAUDE_VERSION = "2.1.0"

def check_claude_version():
    result = subprocess.run(["claude", "--version"], capture_output=True, text=True)
    version = result.stdout.strip()
    if version < MIN_CLAUDE_VERSION:
        print(f"WARNING: Claude Code {version} < minimum {MIN_CLAUDE_VERSION}")

E-002: SQLite WAL Mode

What: Enable Write-Ahead Logging in sessions.db and org.db Why: Prevent SQLITE_BUSY under concurrent hook writes Where: scripts/core/paths.py or database initialization Effort: Small (5 lines per database)

conn = sqlite3.connect(db_path)
conn.execute("PRAGMA journal_mode=WAL")
conn.execute("PRAGMA busy_timeout=5000")

E-003: Task ID Format Normalization

What: Add bidirectional format adapter for E001-T001 <-> A.9.1.3 Why: Eliminate validation warnings from /project-new generated IDs Where: hooks/task-plan-sync.py and hooks/task-tracking-enforcer.py Effort: Medium (30-50 lines)

E-004: SessionStart Hook Cleanup

What: Audit and remove all SessionStart hook references Why: Deprecated per ADR-074, causes race conditions with MCP initialization Where: Setup script, hook configs, documentation Effort: Small (audit + remove)

Priority 2: Robustness

E-005: Hook Error Recovery Framework

What: Replace try/except: pass with structured error recovery Why: Silent failures mask real issues; no visibility into hook health Where: All hook implementations, template in hooks/hook_template.py Effort: Medium (update each hook)

except Exception as e:
    logger.error("Hook failed", error=str(e), traceback=traceback.format_exc())
    # Fail-open but with visibility
    print(json.dumps({"continue": True}))

E-006: Symlink Health Check

What: Post-setup verification + periodic symlink validation Why: Broken symlinks silently disable the entire framework Where: New script scripts/verify-symlinks.py, callable from statusline Effort: Small (20 lines)

E-007: Hook Protocol Versioning

What: Version the hook JSON protocol for forward compatibility Why: Claude Code hook API could change; versioning enables graceful migration Where: All hooks add "protocol_version": "1.0" to output Effort: Small

E-008: Cloud Sync Resilience

What: Verify offline queue persistence across restarts, add queue depth monitoring Why: task-plan-sync.py queues for retry but persistence is unclear Where: hooks/task-plan-sync.py, scripts/core/cloud_sync_client.py Effort: Medium

Priority 3: Observability

E-009: Hook Health Dashboard

What: Real-time hook execution stats command: /hook-health Why: No visibility into hook success rates, latency, or error patterns Where: New command commands/hook-health.md, new script scripts/hook-health-dashboard.py Effort: Medium (parse ~/.coditect/logs/hooks.log)

Metrics to track:

Success/failure rate per hook
Average execution time
Error frequency by type
Last 24h summary

E-010: Statusline Debug Mode

What: Add --debug flag to statusline-command.sh Why: Debugging statusline issues requires manual log inspection Where: scripts/statusline-command.sh Effort: Small

E-011: Cross-Hook Audit Trail

What: Correlate hook events across a single tool invocation lifecycle Why: Currently each hook logs independently; no trace of full lifecycle Where: hooks/hook_logger.py - add correlation ID (tool_use_id) Effort: Medium

Priority 4: Extensibility

E-012: Hook Composition (AND/OR Matchers)

What: Support complex matcher logic beyond single tool name regex Why: Currently one matcher per hook entry; complex conditions require multiple entries Where: CODITECT-CORE-INITIAL-SETUP.py hook registration Effort: Medium - depends on Claude Code matcher API

E-013: Conditional Hook Execution

What: Support if_env, if_file_exists, if_project conditions Why: Reduce unnecessary hook invocations (e.g., skip plan sync if no plan file) Where: hooks/dispatcher.sh - add condition checks before dispatch Effort: Medium

E-014: Hook Template & Validation Tool

What: Standardized hook template with linting/validation Why: 118 hooks with inconsistent patterns; new hooks hard to get right Where: New scripts/validate-hook.py, template at hooks/HOOK-TEMPLATE.py Effort: Medium

6. Testing Recommendations

Before deploying any enhancements:

Hook regression test: Run all 118 hooks with sample inputs, verify JSON output
Concurrent write test: Simulate rapid TodoWrite calls, verify no SQLITE_BUSY
Version compatibility test: Test with Claude Code 2.0.x and 2.1.x
Symlink stress test: Break/repair symlinks, verify graceful degradation
MCP server test: Verify coditect-skills MCP server starts and responds
Statusline test: Run statusline-command.sh under various git states
