profiling-statement-fingerprints

profiling-statement-fingerprints is a skill for Cursor from cockroachdb/cursor-plugin. It costs 59 tokens per session (4,057 once invoked), scanned A, a copy of profiling-statement-fingerprints, Apache-2.0.

A method for examining recurring SQL query patterns using CockroachDB's stored performance statistics. A statement fingerprint groups similar queries so their combined behavior can be measured over time.

In plain words
What is it for?
Use it to rank historical query latency, CPU use, contention, waiting, failures, full table scans, missing-index suggestions, and resource use by application or database.
Why use it?
It helps find slow, resource-heavy, error-prone, or increasingly problematic queries without needing access to the database console.

About the project

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.

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

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.

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
  • VIEWACTIVITY or VIEWACTIVITYREDACTED cluster 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).

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.
