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 | $0.00097 | $0.03438 |
| Opus 5.5 | $0.00039 | $0.01375 |
| Sonnet 5.5 | $0.00019 | $0.00688 |
| Haiku 4.5 | $0.00010 | $0.00344 |
Grade A, and why
reviewing-cluster-health 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 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.

Reviewing Cluster Health
Performs a comprehensive health check of a CockroachDB cluster. Before running diagnostics, this skill gathers deployment context to provide the right queries and tools for the operator's tier.
When to Use This Skill
- Daily or shift-start operational health checks
- Before starting maintenance (Self-Hosted, Advanced, BYOC)
- After incidents to confirm recovery
- Verifying production readiness
- Monitoring capacity and performance
For live query issues: Use triaging-live-sql-activity. For background jobs: Use monitoring-background-jobs. For range analysis: Use analyzing-range-distribution.
Step 1: Gather Context
Required Context
| Question | Options | Why It Matters |
|---|---|---|
| Deployment tier? | Self-Hosted, Advanced, BYOC, Standard, Basic | Determines available diagnostics and operator responsibilities |
| Reason for health check? | Daily check, Pre-maintenance, Post-incident, Pre-upgrade | Prioritizes which dimensions to check first |
Additional Context (by tier)
If Self-Hosted:
| Question | Options | Why It Matters |
|---|---|---|
| Access available? | SQL + CLI, SQL only | Determines which tools can be used |
| Cloud provider? | AWS, GCP, Azure, On-Premises | Affects infrastructure-level checks |
| Kubernetes deployment? | Yes (Operator, Helm, manual), No | Changes CLI commands and monitoring |
| Node count and regions? | e.g., 9 nodes, 3 regions | Sets expectations for query results |
If Advanced or BYOC:
| Question | Options | Why It Matters |
|---|---|---|
| Cloud provider? (BYOC only) | AWS, GCP, Azure | For infrastructure-level monitoring in your cloud account |
What ships with it
1 file 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.
