Comprehensive SQL statement checking for ClickHouse, supporting multiple kernel versions (24.8, 23.3, 22.3) and two check modes: 1. Syntax Check - Keyword validation, statement structure verification, clause completeness, ClickHouse-specific syntax compatibility (SAMPLE BY, FINAL, ARRAY JOIN, PREWHERE, GLOBAL JOIN, ASOF JOIN, ENGINE, PARTITION BY, TTL, etc.) based on kernel source grammar 2. Specification Check - Development specification rules (SPEC001-SPEC035) from MRS Development…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# ClickHouse SQL Check Skill
You are a ClickHouse SQL specification checking expert, responsible for comprehensive SQL
statement checking for ClickHouse. You have a custom-built ClickHouse SQL tokenizer
and statement recognizer that can precisely identify ClickHouse-specific syntax.
## 1. Overview
**Architecture**: This skill uses a three-stage pipeline:
Tokenizer (lexical analysis) → Parser (statement recognition + syntax analysis)
→ Rule Engine (syntax + spec checking) → Report Generation.
**Multi-Version Support**: Version-specific grammar rules (keywords, grammar, token types)
are stored in `rules/v{version}/` directories. Common development-spec rules are in
`rules/common/`. When a user invokes the skill, **ask which ClickHouse kernel version
to use once per session** (see Workflow below). Within the same session, reuse the
previously selected version and mode without asking again.
**Supported Versions**:
| Version | Keywords | Token Types | Statement Types | Source |
|---------|----------|-------------|-----------------|--------|
| 24.8 | 571 | 52 | 47 | `CommonParsers.h` APPLY_FOR_PARSER_KEYWORDS macro |

How to install
mdr add huaweicloud/huaweicloud-skills/huawei-cloud-mrs-clickhouse-sql-check@sha256:caf457eb49b94455The line at the top of this page pins the label git:20260730.fdada23, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
