AgentCash Banner

#!/usr/bin/env bash
# Claude Code status line — AgentCash brand banner.
# Green diagonal slashes (bright left -> fading dark) with a shimmer band that
# travels once per second (requires "refreshInterval": 1 in settings.json),
# the AGENTCASH wordmark, and live wallet balances.
#
# Requirements & privacy:
#   * Balances come from the agentcash CLI (install: https://agentcash.dev/skill.md).
#     If the CLI is not installed, the script never invokes anything and simply
#     renders $0.00 — no other functionality is affected.
#   * The only external command ever run is `agentcash accounts --format json`,
#     a read-only balance query. It runs as a single short-lived background
#     fetch, debounced by a stamp file to at most once per 60s (10s while the
#     cache is cold). Nothing persists after the fetch exits; no daemons.
#   * The "topup" hyperlink embeds YOUR OWN wallet's public deposit address
#     (read from the local cache). Be aware it is visible in the status bar if
#     you screen-share or log terminal output.
#   * State lives in two small cache files under ~/.claude/ and never leaves
#     the machine.
#
# Test with mock input:
#   echo '{}' | COLUMNS=120 ~/.claude/statusline.sh
