From d59c8b679428167f19d62071c0f6a2a87ca8b3b0 Mon Sep 17 00:00:00 2001 From: Franklin Moormann Date: Sun, 2 Nov 2025 16:02:55 -0500 Subject: [PATCH 1/3] fix: resolve powershell parse errors and session file corruption MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit CRITICAL FIXES: 1. PowerShell Parse Error (lines 1598, 1620): - Changed $toolName: to ${toolName}: to avoid drive syntax interpretation - Prevents "Variable reference is not valid" errors - Script can now execute without syntax errors 2. Write-SessionFile Corruption Fix: - Initialize $fileStream = $null and $writer = $null at loop start - Add $writer.Dispose() in finally block - Increase ConvertTo-Json depth from default to 100 - Proper disposal order prevents 0-byte session files 3. Enhanced Debugging: - Added extensive Write-Host checkpoints in Handle-OptimizeToolOutput - Added script version logging - Added DIAGNOSTIC logs for optimize-tool-output action Root Cause Analysis (via Gemini CLI): - Each orchestrator invocation runs in NEW PowerShell process - No shared in-memory state between invocations - current-session.txt is ONLY mechanism for state sharing - Parse error prevented script execution entirely - Improper file disposal caused 0-byte session files 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .../handlers/token-optimizer-orchestrator.ps1 | 306 ++++++++++++------ 1 file changed, 214 insertions(+), 92 deletions(-) diff --git a/hooks/handlers/token-optimizer-orchestrator.ps1 b/hooks/handlers/token-optimizer-orchestrator.ps1 index 401ec9f..0bc2ecc 100644 --- a/hooks/handlers/token-optimizer-orchestrator.ps1 +++ b/hooks/handlers/token-optimizer-orchestrator.ps1 @@ -2,10 +2,28 @@ # Unified handler for ALL token optimization operations # Replaces 15+ fragmented PowerShell handlers with direct MCP calls -# CRITICAL FIX: Removed param block that consumed stdin when dot-sourced! -# The Mandatory=$true parameters were trying to read from stdin during dot-sourcing, -# consuming the JSON input before dispatcher.ps1 could read it. -# Functions now receive their inputs via parameters (e.g., $InputJson) +# Accept Phase, Action, and InputJsonFile (temp file path) from dispatcher +# NOT marked as Mandatory to avoid stdin consumption issues +param( + [string]$Phase = "", + [string]$Action = "", + [string]$InputJsonFile = "" +) + +# DIAGNOSTIC: Log script version/load time to verify latest version is being used +$SCRIPT_VERSION = Get-Date -Format 'yyyyMMdd.HHmmss' +Write-Host "DEBUG: token-optimizer-orchestrator.ps1 version $SCRIPT_VERSION loaded.

This caused ALL background optimization processes to fail immediately with InvalidOperationException. **Error**: "Parameters '-NoNewWindow' and '-WindowStyle' cannot be specified at the same time." **Impact**: Background optimization was spawning but failing instantly, resulting in zero token savings despite processes appearing to start. **Fix**: Removed -NoNewWindow parameter, kept -WindowStyle Hidden **Evidence**: Dispatcher logs showed "BACKGROUND: Starting optimize-tool-output" with spawn times of ~100-130ms, but orchestrator logs showed NO execution, and current-session.txt showed zero optimization stats despite 383 operations. This explains why totalOperations incremented but all optimization stats remained at 0. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- hooks/dispatcher.ps1 | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/hooks/dispatcher.ps1 b/hooks/dispatcher.ps1 index 8bc3b3d..acc6187 100644 --- a/hooks/dispatcher.ps1 +++ b/hooks/dispatcher.ps1 @@ -164,7 +164,7 @@ try { # This allows hooks to return immediately while optimization runs async $actionStart = Get-Date Write-Log "BACKGROUND: Starting optimize-tool-output in background process" - Start-Process -FilePath "powershell" -ArgumentList "-NoProfile","-ExecutionPolicy","Bypass","-File",$ORCHESTRATOR,"-Phase","PostToolUse","-Action","optimize-tool-output","-InputJsonFile",$tempFile -WindowStyle Hidden -NoNewWindow + Start-Process -FilePath "powershell" -ArgumentList "-NoProfile","-ExecutionPolicy","Bypass","-File",$ORCHESTRATOR,"-Phase","PostToolUse","-Action","optimize-tool-output","-InputJsonFile",$tempFile -WindowStyle Hidden $actionDuration = ((Get-Date) - $actionStart).TotalMilliseconds Write-Log "TIMING: optimize-tool-output background spawn took ${actionDuration}ms"
