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 | $0.00022 | $0.01126 |
| Opus 5 | $0.00011 | $0.00563 |
| Sonnet 5 | $0.00004 | $0.00225 |
| Haiku 4.5 | $0.00002 | $0.00113 |
Grade A, and why
optimize-clickhouse-sql 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.

No licence file
A repository with no LICENSE is all rights reserved by default, so the body is not copied here. The metadata, the measurements and the link are.
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.

optimize-clickhouse-sql is a skill published in the GitHub repository FrankChen021/datastoria (326 stars, last pushed 1mo ago), with no licence file. It adds 22 tokens to every session and 1,126 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

dbx
DBX CLI for database schema exploration and read-only queries. When the user needs to list connections, explore tables, describe schemas, run queries, or generate AI-friendly schema context from DBX-managed databases. Do NOT use for write operations unless the user explicitly confirms with --allow-writes.
migration-patterns
Schema migrations: ALTER patterns, engine changes, zero-downtime swaps, clickhouse-local offline migrations, lightweight UPDATE/DELETE strategies, and Postgres→ClickHouse migration planning (type mapping, schema pitfalls, PeerDB CDC, validation, schema introspection).
incident-response
Structured triage recipes for common ClickHouse incidents: disk, errors, replication, mutations, cluster health, and slow queries.
concept-explainer
Explains core ClickHouse concepts with accurate mental models — MergeTree, indexes, replication, sharding, and special engines.
data-analysis
Analyze cluster data and metrics using raw SQL recipes against system.querylog and system.parts when no dedicated tool exists.
hardware-tuning
Detect server cores/RAM/disk from system tables, then recommend ClickHouse settings sized to that hardware.
