Ready‑to‑Use OPA Policy Templates for OpenClaw Edge Token‑Bucket Rate Limiter

Open Policy Agent (OPA) Policy Templates for OpenClaw Edge Token‑Bucket Rate Limiter

This article provides concrete, ready‑to‑use OPA policy templates that you can copy‑paste into your OpenClaw Edge deployment. The templates cover common scenarios such as per‑agent limits, burst control, and dynamic quota adjustments.

1. Per‑Agent Limits

package openclaw.rate_limit

# Define a token bucket per agent
default allow = false

allow {
    input.agent = agent
    token_bucket[agent].tokens >= 1
    token_bucket[agent].tokens = token_bucket[agent].tokens - 1
}

# Initialize token bucket (example for agent "agent‑123")
token_bucket["agent‑123"] = {"tokens": 100, "capacity": 100, "refill_rate": 10}

2. Burst Control

package openclaw.rate_limit

# Allow bursts up to a defined limit
allow {
    input.agent = agent
    bucket := token_bucket[agent]
    bucket.tokens >= 1
    bucket.tokens = bucket.tokens - 1
    # Record burst usage (optional)
    burst_usage[agent] = bucket.tokens
}

# Example bucket with burst capacity
token_bucket["agent‑456"] = {"tokens": 50, "capacity": 200, "refill_rate": 20}

3. Dynamic Quota Adjustments

package openclaw.rate_limit

# Adjust quota based on external metrics (e.g., load)
adjust_quota(agent, new_capacity) {
    token_bucket[agent].capacity = new_capacity
    token_bucket[agent].tokens = min(token_bucket[agent].tokens, new_capacity)
}

# Example adjustment call (could be triggered by a webhook)
adjust_quota("agent‑789", 500)

Feel free to adapt these snippets to your specific environment.
