burnrate v1.0.0: Flagship Production 1.0 Release

⚡ burnrate v1.0.0 Production Flagship Release

Never wake up to an unexpected 0 Claude Code or Cursor bill again.
Terminal HUD, hard spend breakers, prompt-cache linting, model cost cascade routing, multi-agent quotas, and velocity brakes in pure Rust.

🌟 Flagship Architecture

• In-Line Hard Spend Circuit Breaker (src/budget.rs): Immediate HTTP 402 termination when session caps are hit.
• Prompt-Cache Invalidation Linter (src/cache_linter.rs): Catches prefix drift (dynamic timestamps, unsorted JSON) that bust the 90% cache discount.
• Token-Cost Optimal Cascade Router (src/router.rs): Dynamically downgrades tasks when budgets run low to preserve funds.
• Team Budget Pool & Multi-Agent Partitioning (src/team.rs): Partition shared budget pools across subagents (e.g. planner, coder, reviewer).
• Sliding-Window Token Velocity Brake (src/velocity.rs): Guards against runaway infinite loop consumption.
• Prometheus Observability (/metrics & src/metrics.rs): Enterprise Prometheus text exposition format for Grafana dashboards.
• Zero-Lag SSE Streaming Counter (src/streaming.rs): Tracks stream consumption on the wire.
• Native MCP stdio Server (burnrate mcp): Drop-in Model Context Protocol server for Claude Desktop, Cursor, and Hermes.
• Official Client SDKs: Python (burnrate-agent) & TypeScript.

📦 Installation

cargo install burnrate-agent

🧪 Verification & Benchmarks

• 12/12 Tests Passing across all modules.
• Published to Crates.io: https://crates.io/crates/burnrate-agent

burnrate v0.5.0: Production FinOps Suite with Python & TypeScript SDKs

⚡ burnrate v0.5.0 Release

Never wake up to an unexpected 0 Claude Code or Cursor bill again.
Hard spend circuit breakers, byte-level prompt-cache linting, and full client SDK support.

🚀 What's New in v0.5.0

• Native MCP stdio Server (burnrate mcp): Zero-overhead Model Context Protocol integration for Claude Desktop, Cursor, and Hermes.
• Zero-Lag Streaming SSE Token Counter (src/streaming.rs): Ingests streaming responses on the wire without buffering or adding latency.
• Context Window Explosion Guard (src/context_guard.rs): Alerts before an agent reads massive lockfiles or SQLite databases into context.
• Multi-Language Client SDKs:
  • Python SDK (sdk/python/burnrate)
  • TypeScript SDK (sdk/typescript)
• Published on Crates.io: https://crates.io/crates/burnrate-agent

burnrate v0.1.0: Terminal HUD, Hard Spend Caps & Cache Guard

⚡ burnrate v0.1.0 Release

Never wake up to an unexpected 0 Claude Code or Cursor bill again.
Terminal HUD, hard spend breakers, and instant prompt-cache leak alerts.

🚀 Features

• Hard Spend Circuit Breaker: Terminates runaway agent loops the moment max_spend is breached.
• Prompt-Cache Invalidation Linter: Detects byte-level prefix drift (e.g. dynamic timestamps or unsorted JSON) that bust the 90% prompt-cache discount.
• Live Terminal HUD: Renders an ANSI status bar displaying spend, burn rate ($/min), turns, and cache hit rates.
• Reverse Proxy Daemon (burnrate serve): In-line proxy supporting Anthropic and OpenAI wire protocol formats.
• Command Wrapper (burnrate run): Easily wrap claude, opencode, or custom agent loops with budget limits.

📦 Installation

cargo install burnrate-agent

🧪 Verification & Health

• 5/5 Tests Passing in CI.
