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 | $0.00080 | $0.04724 |
| Opus 5.5 | $0.00032 | $0.01890 |
| Sonnet 5.5 | $0.00016 | $0.00945 |
| Haiku 4.5 | $0.00008 | $0.00472 |
Grade A, and why
profiling-transaction-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-transaction-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.

Profiling Transaction Fingerprints
Analyzes historical transaction performance patterns using aggregated SQL statistics to identify high-retry transactions, contention patterns, and commit latency issues. Uses crdb_internal.transaction_statistics for time-windowed analysis of retry behavior, commit latency, and statement composition - entirely via SQL without requiring DB Console access.
Complement to profiling-statement-fingerprints: This skill analyzes transaction-level patterns (groups of statements with retry behavior); for statement-level optimization, see profiling-statement-fingerprints.
Complement to triaging-live-sql-activity: This skill analyzes historical transaction patterns; for immediate triage of currently active transactions, see triaging-live-sql-activity.
When to Use This Skill
- Identify transactions with high retry counts
- Analyze commit latency trends for transaction fingerprints
- Find transactions with high contention at transaction boundary
- Understand statement composition of problematic transactions
- Investigate transaction retry storms or abort patterns
- SQL-only historical transaction analysis without DB Console access
For immediate incident response: Use triaging-live-sql-activity to triage currently active transactions and cancel runaway work. For statement-level optimization: Use profiling-statement-fingerprints to analyze individual query patterns.
Prerequisites
- SQL connection to CockroachDB cluster
VIEWACTIVITYorVIEWACTIVITYREDACTEDcluster privilege for cluster-wide visibility- Same privilege requirements as profiling-statement-fingerprints
- Understanding of transaction performance concepts
- Transaction statistics collection enabled (default):
sql.stats.automatic_collection.enabled = true
Check transaction stats collection:
SHOW CLUSTER SETTING sql.stats.automatic_collection.enabled;
-- Should return: true
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-transaction-fingerprints is a skill published in the GitHub repository cockroachdb/claude-plugin (4 stars, last pushed 28d ago), licensed Apache-2.0. It adds 80 tokens to every session and 4,724 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to profiling-transaction-fingerprints, differing in 0 lines, and is treated as a copy.
