Track LLM API spend per session and task. Estimate token usage across providers. Warn before you blow your budget. Use when estimating task cost, checking token usage, or setting a session budget.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 💰 Cost Tracker
> Uses the Agent Skills package format. Execution depends on the host tools and permissions; consult the frontmatter compatibility requirements where provided.
Track what your AI sessions actually cost. Estimate token usage, cumulative spend, and warn you before you hit budget thresholds — across OpenAI, Anthropic, Google, and other major providers.
---
## Triggers
Activate this skill when:
- User asks "how much has this session cost?"
- User asks "what's my token usage?"
- User sets a session budget ("keep this under $2")
- User wants a cost estimate before a large task
- Cumulative session spend needs tracking
- "track my costs", "budget check", "token count", "how much am I spending"

How to install
mdr add suryast/free-ai-agent-skills/cost-tracker@sha256:3f28d8ffb921259fThe line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
