# Tokdash -> Claude Code statusline (PowerShell / native Windows starter)
# -------------------------------------------------------------------------------
# Renders one line, e.g.:   [Claude Sonnet 4.6] 📁 myproject | 📊 12.3M ($4.56) today
#
# Requires: PowerShell 5.1+ (Invoke-RestMethod / ConvertFrom-Json are built in --
# no curl or jq needed). Fails silently (drops the 📊 segment) if tokdash isn't
# running. This script only ever issues GET requests, so the write-protection
# gate never blocks it.
#
# Install:
#   1. copy statusline.ps1 to %USERPROFILE%\.claude\scripts\statusline.ps1
#   2. add the Windows "statusLine" block from this folder's README.md to
#      %USERPROFILE%\.claude\settings.json
#
# If you changed TOKDASH_HOST / TOKDASH_PORT, point the script at your endpoint,
# e.g. in your PowerShell profile:
#   $env:TOKDASH_URL = "http://127.0.0.1:55423"
#
# This is the PowerShell counterpart of statusline-minimal.sh -- keep the two in
# sync if you change one.
