CockroachDB Plugin for Cursor connects the Cursor coding agent to CockroachDB clusters for database work such as exploring schemas, writing SQL, debugging queries, and managing distributed clusters. It supports self-hosted and CockroachDB Cloud connections, and its catalogue add-ons provide database-focused agents, skills, rules, and instructions.
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 | $0.00087 | $0.03314 |
| Opus 5.5 | $0.00035 | $0.01326 |
| Sonnet 5.5 | $0.00017 | $0.00663 |
| Haiku 4.5 | $0.00009 | $0.00331 |
Grade B, and why
performing-cluster-maintenance scanned grade B with 2 findings 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 2mo 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Performing Cluster Maintenance
Manages planned cluster maintenance across all deployment tiers. For Self-Hosted, this means draining and restarting individual nodes. For Advanced/BYOC, this means configuring and managing maintenance windows for CRL-applied patches. For Standard and Basic, maintenance is fully managed with no customer action required.
When to Use This Skill
- Planning OS patching, hardware changes, or configuration updates (Self-Hosted)
- Configuring or modifying a maintenance window (Advanced, BYOC)
- Setting patch deferral policies (Advanced, BYOC)
- Monitoring during a CRL-managed maintenance event (Advanced, BYOC)
- Running pre-maintenance validation checks (Self-Hosted, Advanced, BYOC)
- Understanding how maintenance affects your application (all tiers)
- Preparing applications for maintenance events (all tiers)
For permanent node removal: Use managing-cluster-capacity. For pre-maintenance health check: Use reviewing-cluster-health. For version upgrades: Use upgrading-cluster-version.
Step 1: Gather Context
Required Context
| Question | Options | Why It Matters |
|---|---|---|
| Deployment tier? | Self-Hosted, Advanced, BYOC, Standard, Basic | Determines maintenance procedure |
| Goal? | Plan maintenance, Configure maintenance window, Defer a patch, Monitor during maintenance, Prepare application | Routes to the right procedure |
Additional Context (by tier)
If Self-Hosted:
| Question | Options | Why It Matters |
|---|---|---|
| Maintenance type? | OS patching, Hardware change, Binary upgrade, Config change, Planned restart | Affects sequencing and post-maintenance steps |
| Deployment platform? | Bare metal, VMs, Kubernetes (Operator/Helm/manual) | Changes drain and restart commands |
| Process manager? | systemd, manual, container orchestrator | Changes stop/start commands |
| Target node ID? | Node ID | Required for drain command |
| Long-running queries expected? | Yes (increase drain timeout), No (default timeout) | Determines drain-wait parameter |
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

performing-cluster-maintenance is a skill published in the GitHub repository cockroachdb/cursor-plugin (2 stars, last pushed 28d ago), licensed Apache-2.0. It adds 87 tokens to every session and 3,314 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it B with 2 findings (asks for root, makes network calls). It is 100% identical to performing-cluster-maintenance, differing in 0 lines, and is treated as a copy.
