* fix(logger): handle non-JSON tool_input in formatTool (#545)

Wrap JSON.parse in try-catch to handle raw string inputs (e.g., Bash
commands) that aren't valid JSON. Falls back to using the string as-is.

* fix(tests): clean up flaky tests and fix circular dependency

Phase 1 of test quality improvements:

- Delete 6 harmful/worthless test files that used problematic mock.module()
  patterns or tested implementation details rather than behavior:
  - context-builder.test.ts (tested internal implementation)
  - export-types.test.ts (fragile mock patterns)
  - smart-install.test.ts (shell script testing antipattern)
  - session_id_refactor.test.ts (outdated, tested refactoring itself)
  - validate_sql_update.test.ts (one-time migration validation)
  - observation-broadcaster.test.ts (excessive mocking)

- Fix circular dependency between logger.ts and SettingsDefaultsManager.ts
  by using late binding pattern - logger now lazily loads settings

- Refactor mock.module() to spyOn() in several test files for more
  maintainable and less brittle tests:
  - observation-compiler.test.ts
  - gemini_agent.test.ts
  - error-handler.test.ts
  - server.test.ts
  - response-processor.test.ts

All 649 tests pass.

- Remove mock-heavy query tests from observation-compiler.test.ts, keep real buildTimeline tests
- Convert session_id_usage_validation.test.ts from 477 to 178 lines of focused smoke tests
- Remove tests for language built-ins from worker-spawn.test.ts (JSON.parse, array indexing)
- Rename logger-coverage.test.ts to logger-usage-standards.test.ts for clarity

# Issue #543 Analysis: /claude-mem Slash Command Not Available Despite Installation
**Date:** 2026-01-05
**Version Analyzed:** 8.5.9
**Status:** Expected Behavior - No such command exists
**Related Issues:** #557 (if it exists), Windows initialization issues
## Issue Summary
A user reports that the `/claude-mem diagnostics` command returns "Unknown slash command: claude-mem" after installing claude-mem v8.5.9 on Windows.
### Reported Environment
- Claude-mem version: 8.5.9
- Claude Code version: 2.0.76
- Node.js version: v22.21.0
- Bun version: 1.3.5
- OS: Windows 10.0.26200.7462 (x64)
### Reported Plugin Status
- Worker Running: No
- Database Exists: Yes (4.00 KB - minimal/empty database)
- Settings Exist: No
## Root Cause Analysis
### Finding 1: No `/claude-mem` Slash Command Exists
**Critical Discovery**: The `/claude-mem diagnostics` command does not exist in claude-mem. After extensive codebase analysis:
1. **No slash command registration found**: The `plugin/commands/` directory is empty. Claude-mem does not register any slash commands.
2. **Skills, not commands**: Claude-mem uses Claude Code's **skill system**, not the command system. Skills are defined in `plugin/skills/`:
- `mem-search/` - Memory search functionality
- `troubleshoot/` - Troubleshooting functionality
- `search/` - Search operations
- `claude-mem-settings/` - Settings management
3. **Empty skill directories**: All skill directories currently contain only empty subdirectories (`operations/`, `principles/`) with no SKILL.md files present in the built plugin. This suggests either:
- Skills are dynamically loaded from the worker service
- A build issue where skill files are not being bundled
- Skills were removed or relocated in a recent refactor
### Finding 2: How Troubleshooting Actually Works
According to the documentation (`docs/public/troubleshooting.mdx`):
> "Describe any issues you're experiencing to Claude, and the troubleshoot skill will automatically activate to provide diagnosis and fixes."
The troubleshoot skill is designed to be **invoked naturally** - users describe their problem to Claude, and the skill auto-invokes. There is no `/claude-mem diagnostics` command.
### Finding 3: Settings.json Creation Flow
The `settings.json` file is **not created during installation**. It is created:
1. **On first worker API call**: The `ensureSettingsFile()` method in `SettingsRoutes.ts` (lines 400-413) creates the file with defaults when the settings API is first accessed.
2. **Worker must be running**: Since settings creation is triggered by API calls, the worker service must be running for settings to be created.
3. **Lazy initialization pattern**: This is intentional - settings are created on-demand with sensible defaults rather than during installation.
### Finding 4: Worker Service Not Running
The user reports "Worker Running: No". This is the core issue because:
1. **Worker auto-start on SessionStart**: The `hooks.json` shows the worker starts via:
```json
{
"type": "command",
"command": "bun \"${CLAUDE_PLUGIN_ROOT}/scripts/worker-service.cjs\" start",
"timeout": 60
}
```
2. **Smart-install runs first**: Before worker start, `smart-install.js` runs to ensure Bun and uv are installed.
3. **Windows-specific issues**: The user is on Windows, which has known issues:
- PowerShell escaping problems in `cleanupOrphanedProcesses()` (Issue #517)
- PATH issues with freshly installed Bun
- Process spawning differences
### Finding 5: Database Size Indicates No Data
The database is 4.00 KB, which is essentially an empty schema:
- No observations recorded
- No sessions created
- Hooks may not have executed successfully
## Initialization Flow Analysis
```
Installation
|
v
First Session Start
|
+---> smart-install.js (ensure Bun + uv)
| |
| +---> May fail silently on Windows (PATH issues)
|
+---> worker-service.cjs start
| |
| +---> Likely failing (worker not running)
|
+---> context-hook.js (requires worker)
| |
| +---> Fails or returns empty (no worker)
|
+---> user-message-hook.js
|
+---> No context injected
```
## Why Skills Directories Are Empty
After investigation, the skill directories in `plugin/skills/` are scaffolding structures but appear to have no SKILL.md files in the built plugin. The actual skill functionality may be:
1. **Served via HTTP API**: The Server.ts shows an `/api/instructions` endpoint that loads SKILL.md sections on-demand from `../skills/mem-search/`
2. **Built differently**: The skills may be bundled into the worker service rather than standalone files
3. **Documentation discrepancy**: The README and docs reference skills that may work differently than traditional Claude Code skill files
## Proposed Diagnosis
The user's issue is **not** that `/claude-mem diagnostics` doesn't work - that command never existed. The actual issues are:
1. **Misunderstanding of troubleshoot functionality**: The user expects a slash command but should describe issues naturally to Claude.
2. **Worker service failed to start**: Root cause for:
- No settings.json created
- Empty database (no observations)
- No context injection working
3. **Possible Windows initialization failures**:
- Bun may not be in PATH after smart-install
- PowerShell execution policy issues
- Worker spawn failures
## Recommended User Resolution
### Step 1: Verify Bun Installation
```powershell
bun --version
```
If not found, manually install:
```powershell
powershell -c "irm bun.sh/install.ps1 | iex"
```
Then restart terminal.
### Step 2: Manually Start Worker
```powershell
cd ~/.claude/plugins/marketplaces/thedotmack
bun plugin/scripts/worker-service.cjs start
```
### Step 3: Verify Worker Health
```powershell
curl http://localhost:37777/health
```
### Step 4: Create Settings Manually (if needed)
```powershell
curl http://localhost:37777/api/settings
```
This will create `~/.claude-mem/settings.json` with defaults.
### Step 5: For Diagnostics - Natural Language
Instead of `/claude-mem diagnostics`, describe the issue to Claude:
> "I'm having issues with claude-mem. Can you help troubleshoot?"
The troubleshoot skill should auto-invoke if the worker is running.
## Proposed Code Improvements
### 1. Add Diagnostic Slash Command
Create a `/claude-mem` command for diagnostics. File: `plugin/commands/claude-mem.json`:
```json
{
"name": "claude-mem",
"description": "Claude-mem diagnostics and status",
"handler": "scripts/diagnostic-command.js"
}
```
### 2. Eager Settings Creation
Modify `smart-install.js` to create settings.json during installation:
```javascript
const settingsPath = join(homedir(), '.claude-mem', 'settings.json');
if (!existsSync(settingsPath)) {
mkdirSync(join(homedir(), '.claude-mem'), { recursive: true });
writeFileSync(settingsPath, JSON.stringify(getDefaults(), null, 2));
console.log('Created settings.json with defaults');
}
```
### 3. Better Windows Error Reporting
Add explicit error messages when worker fails to start on Windows:
```javascript
if (process.platform === 'win32' && !workerStarted) {
console.error('Worker failed to start on Windows.');
console.error('Please run manually: bun plugin/scripts/worker-service.cjs start');
console.error('And check: https://docs.claude-mem.ai/troubleshooting');
}
```
### 4. Health Check Command
Add a simple health check that works without the worker:
```javascript
// plugin/scripts/health-check.js
const http = require('http');
http.get('http://localhost:37777/health', (res) => {
if (res.statusCode === 200) console.log('Worker: RUNNING');
else console.log('Worker: NOT RESPONDING');
}).on('error', () => console.log('Worker: NOT RUNNING'));
```
## Relationship to Issue #557
If Issue #557 relates to initialization issues, this analysis confirms:
- Settings.json creation is lazy (requires worker)
- Worker auto-start can fail silently on Windows
- Users may have incomplete installations without clear error messages
## Files Examined
- `/plugin/.claude-plugin/plugin.json` - Plugin manifest (no commands)
- `/plugin/hooks/hooks.json` - Hook definitions
- `/plugin/scripts/smart-install.js` - Installation script
- `/plugin/scripts/worker-service.cjs` - Worker service
- `/src/services/worker/http/routes/SettingsRoutes.ts` - Settings creation
- `/src/shared/SettingsDefaultsManager.ts` - Default values
- `/src/shared/paths.ts` - Path definitions
- `/docs/public/troubleshooting.mdx` - User documentation
- `/docs/public/usage/getting-started.mdx` - User guide
## Conclusion
The reported issue is a **user expectation mismatch** combined with a **Windows initialization failure**:
1. `/claude-mem diagnostics` does not exist - users should use natural language to invoke the troubleshoot skill
2. The worker service failed to start, causing cascading issues (no settings, no context)
3. Documentation could be clearer about available commands vs skills
4. Windows-specific initialization issues are a known pattern
The fix should include both user documentation improvements and potentially adding a `/claude-mem` diagnostic command for discoverability.
