CockroachDB Plugin for Claude Code connects Claude Code to CockroachDB clusters, which are distributed databases, so the agent can work with schemas, SQL queries, and database operations. It is intended for developers, database administrators, and operators working with self-hosted or CockroachDB Cloud deployments. The catalogue entries provide its MCP connections, specialized agents, skills, and safety hooks.
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 | $0.00059 | $0.04057 |
| Opus 5.5 | $0.00024 | $0.01623 |
| Sonnet 5.5 | $0.00012 | $0.00811 |
| Haiku 4.5 | $0.00006 | $0.00406 |
Grade A, and why
profiling-statement-fingerprints 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 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.
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.
This is a copy
100% identical to profiling-statement-fingerprints — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 330 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Profiling Statement Fingerprints
Analyzes historical statement performance patterns using aggregated SQL statistics to identify slow, resource-intensive, or error-prone query fingerprints. Uses crdb_internal.statement_statistics for time-windowed analysis of latency, CPU, contention, admission delays, and failure rates - entirely via SQL without requiring DB Console access.
Complement to triaging-live-sql-activity: This skill analyzes historical patterns; for immediate triage of currently running queries, see triaging-live-sql-activity.
When to Use This Skill
- Identify slowest statement fingerprints over past hours/days/weeks
- Find queries with high CPU consumption, contention, or admission waits
- Investigate performance regressions or plan changes
- Locate full table scans or missing indexes via index recommendations
- Analyze resource consumption by application or database
- SQL-only historical analysis without DB Console access
For immediate incident response: Use triaging-live-sql-activity to triage currently running queries and cancel runaway work. For transaction-level analysis: Use profiling-transaction-fingerprints to analyze retry patterns, commit latency, and statement composition at the transaction boundary. For background job monitoring: Use monitoring-background-jobs for long-running schema changes and automatic jobs excluded from statement statistics.
Prerequisites
- SQL connection to CockroachDB cluster
VIEWACTIVITYorVIEWACTIVITYREDACTEDcluster privilege for cluster-wide visibility- Statement statistics collection enabled (default):
sql.stats.automatic_collection.enabled = true
Check collection status:
SHOW CLUSTER SETTING sql.stats.automatic_collection.enabled; -- Should return: true
See triaging-live-sql-activity permissions reference for RBAC setup (same privileges).
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.

profiling-statement-fingerprints is a skill published in the GitHub repository cockroachdb/claude-plugin (4 stars, last pushed 28d ago), licensed Apache-2.0. It adds 59 tokens to every session and 4,057 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to profiling-statement-fingerprints, differing in 0 lines, and is treated as a copy.
