session-start-reminder.ps1 — wired to the PreToolUse hook in ~/.claude/settings.json (Windows)

PowerShell equivalent of session-start-reminder.sh — injects a memory-load

reminder before the first tool use of each new session, then stays silent.

Requires: PowerShell 5.1+ (built into Windows 10/11) or PowerShell 7+

Install: add to %USERPROFILE%.claude\settings.json:

"hooks": { "PreToolUse": [{ "matcher": ".*", "hooks": [{ "type": "command",

"command": "powershell -NonInteractive -File %USERPROFILE%\.claude\scripts\session-start-reminder.ps1" }] }] }

$ClaudeDir = Join-Path $env:USERPROFILE '.claude' $MemoryDir = Join-Path $ClaudeDir 'memory' $SessionMarker = Join-Path $MemoryDir '.session-active' $DATE = Get-Date -Format 'yyyy-MM-dd'

Already active this session — stay silent

if (Test-Path $SessionMarker) { exit 0 }

Mark session as active to prevent repeat output on subsequent tool calls

New-Item -ItemType Directory -Force -Path $MemoryDir | Out-Null New-Item -ItemType File -Force -Path $SessionMarker | Out-Null
