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 | $0.00080 | $0.04724 |
| Opus 5 | $0.00040 | $0.02362 |
| Sonnet 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 3d 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/cursor-plugin (1 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 80 tokens to every session and 4,724 once invoked, about $0.0004 per session on Opus 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.
