managing-cluster-settings

Guidance for reviewing and changing CockroachDB cluster settings, which control database behavior and performance. The settings available depend on whether the cluster is self-hosted or managed by CockroachDB.

In plain words
What is it for?
Use it to check production readiness, find settings that differ from defaults, tune performance or replication, investigate a specific issue, and verify settings after an upgrade.
Why use it?
It helps you audit configuration, tune a cluster safely, and understand which changes your deployment type allows.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

managing-cluster-settings scanned grade A with 0 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 yesterday.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

Managing Cluster Settings

Reviews, audits, and modifies CockroachDB cluster settings. Before providing procedures, this skill gathers context to determine which settings are available and which modification approach to recommend for the operator's tier.

When to Use This Skill

  • Auditing cluster configuration for production readiness
  • Identifying settings that deviate from defaults
  • Tuning performance, replication, or admission control
  • Verifying settings after an upgrade or incident
  • Understanding which settings are modifiable on your tier
  • Managing enterprise license installation and renewal (Self-Hosted)

For version management: Use upgrading-cluster-version — do not change settings during an upgrade. For health checks: Use reviewing-cluster-health.


Step 1: Gather Context

Required Context

Question Options Why It Matters
Deployment tier? Self-Hosted, Advanced, BYOC, Standard, Basic Determines which settings are viewable and modifiable
Goal? Audit/review, Tune performance, Fix specific issue, Post-upgrade verification Directs which queries and procedures to use

Additional Context (by tier)

If Self-Hosted:

Question Options Why It Matters
SQL access level? admin, MODIFYCLUSTERSETTING, VIEWCLUSTERSETTING Determines available operations
Specific setting or area? e.g., "timeout", "replication", "gc" Narrows search to relevant settings
Currently mid-upgrade? Yes, No Settings must NOT be changed during rolling upgrades

If Advanced or BYOC:

Question Options Why It Matters
SQL access level? admin, limited Determines available operations
Specific setting or area? e.g., "timeout", "rangefeed" Narrows search

If Standard or Basic: No additional context needed — settings access is limited. Session variables are the primary tuning mechanism.

What ships with it

5 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.

Changes

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.
