Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00066 | $0.01646 |
| Opus 5 | $0.00033 | $0.00823 |
| Sonnet 5 | $0.00013 | $0.00329 |
| Haiku 4.5 | $0.00007 | $0.00165 |
Grade A, and why
configuring-ip-allowlists scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Configuring IP Allowlists
Configures and hardens IP allowlists on CockroachDB Cloud clusters to restrict SQL and DB Console access to authorized CIDR ranges. Identifies overly permissive entries (such as 0.0.0.0/0) and replaces them with specific, narrow ranges.
When to Use This Skill
- Removing
0.0.0.0/0(open to all) from the IP allowlist - Restricting network access after initial cluster setup
- Adding office, VPN, or CI/CD CIDR ranges to the allowlist
- Reviewing and tightening existing allowlist entries
- Responding to a security audit finding about overly broad network access
Prerequisites
- ccloud CLI installed and authenticated (
ccloud auth login) - Cloud Console role: Cluster Admin or Cluster Operator
- Known CIDR ranges: Office IPs, VPN egress IPs, CI/CD runner IPs, or other authorized sources
- Cluster ID: Available from
ccloud cluster list
Verify access:
ccloud auth whoami
ccloud cluster list
Steps
1. List Current Allowlist Entries
# List all IP allowlist entries for the cluster
ccloud cluster networking allowlist list <cluster-id> -o json
Review each entry. Flag any of these as overly permissive:
0.0.0.0/0— Open to all IPv4 addresses/8ranges — 16 million+ addresses/16ranges — 65,000+ addresses- Unknown or undocumented entries
See ccloud commands reference for full command syntax.
2. Understand Allowlist Limits
CockroachDB Cloud clusters have a maximum number of IP allowlist entries per cluster. If you need more entries than the limit allows:
- Consolidate entries: Use broader CIDR ranges where security permits (e.g., combine several
/32entries into a/24) - Use private endpoints: Switch to private endpoints instead of allowlists for VPC-based access — private endpoints bypass the allowlist entirely
- Request a limit increase: Contact CockroachDB Cloud support if consolidation and private endpoints are not sufficient

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

configuring-ip-allowlists is a skill published in the GitHub repository cockroachlabs/cockroachdb-skills (21 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 66 tokens to every session and 1,646 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
