Token Guard 💰

Stop burning money while you sleep.

Your AI agent runs 24/7. Opus costs $75/M output tokens. One overnight coding session can burn $50+ before you wake up. Token Guard watches your spend and acts before your wallet notices.

The Problem

Real costs from real users:

ScenarioModelCost
"Let the agent run overnight"Opus$50-100
"Register an email + X account"Opus$55 (one task!)
First week exploringOpus$100+
Daily heartbeat checksOpus$2-5/day for nothing

Most users don't realize they're burning Opus-level tokens on tasks that Haiku could handle.

What Token Guard Does

Monitor

  • Track token usage per day/model
  • Estimate costs from model pricing
  • Show usage history and trends

Budget

  • Set daily spending limits
  • Warning alerts at configurable threshold (default 80%)
  • Hard limits with auto-model-downgrade

Optimize

  • Model cost comparison at a glance
  • Routing recommendations (Opus for reasoning, Haiku for background)
  • Per-task cost estimation before running

Quick Start

# See current usage and model costs
bash scripts/token-guard.sh status

# Set a $10/day budget with warnings
bash scripts/token-guard.sh set-budget 10

# Set a hard limit: auto-downgrade to Haiku when exceeded
bash scripts/token-guard.sh set-budget 10 80 true claude-haiku-3-5

# Estimate cost before running a task
bash scripts/token-guard.sh estimate claude-opus-4 50000 10000 10

# Check usage history
bash scripts/token-guard.sh history 7

Model Cost Comparison

Claude Opus 4$15.00$75.00100x
Claude Sonnet 4$3.00$15.0020x

Recommended Routing

Tier 1 (Reasoning/Creative):  claude-opus-4      → Use sparingly
Tier 2 (Daily work):          claude-sonnet-4     → Primary model
Tier 3 (Background/Subagent): claude-haiku-3-5    → Subagent model
Tier 4 (Bulk/Heartbeat):      gemini-2.0-flash    → Heartbeat/cron

Savings: Routing background tasks to Haiku instead of Opus = 95% cost reduction on those tasks.

For AI Agents

Add to your heartbeat or cron:

bash /path/to/token-guard/scripts/token-guard.sh monitor

When budget is exceeded with hard limit enabled, the script automatically downgrades the primary model.
