Set per-request, per-session, daily, and monthly spend limits, configure rate limiting and circuit breakers, and isolate costs per user or tenant.
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 and Budget Enforcement
## Agent objective
Produce a builder with cost tracking, budget limits, and rate limiting configured so the agent never exceeds defined spending thresholds.
## When to load this skill
- Deploying agents in production with real API costs
- Building multi-tenant SaaS where per-user cost isolation matters
- Protecting against runaway agent loops consuming excessive tokens
- Adding circuit breakers for provider reliability
## Implementation baseline
```ts
import { ReactiveAgents } from "@reactive-agents/runtime";
const agent = await ReactiveAgents.create()
.withName("assistant")
.withProvider("anthropic")
.withReasoning({ defaultStrategy: "adaptive", maxIterations: 15 })
.withTools({ allowedTools: ["web-search", "http-get", "checkpoint"] })
.withCostTracking({
perRequest: 0.25, // max $0.25 per LLM call
perSession: 2.0, // max $2.00 per agent.run() call
daily: 10.0, // max $10.00/day across all sessions
monthly: 100.0, // max $100.00/month
})
.withRateLimiting({
requestsPerMinute: 30,
tokensPerMinute: 50_000,
maxConcurrent: 3,
})

How to install
mdr add tylerjrbuell/reactive-agents-ts/cost-budget-enforcement@sha256:db1c190516ec6c0dThe line at the top of this page pins the label v2.0, 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.
