What it does

Update Keyword Engine Lists is an agent skill from ClickHouse/clickhouse-java. Update ALLOWEDKEYWORDALIASES in ClickHouseSqlUtils.java and ENGINETOTABLETYPE in DatabaseMetaDataImpl.java from failing test output. Use when StatementSQLTest.testAllowedKeywordAliasesMatchSystemKeywords or DatabaseMetaDataTest.testAllTableEnginesFromSystemTableEnginesAreMapped fails.

Its SKILL.md is about 460 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Databases, covering Failing and flaky tests and Data warehousing. It works with Java and ClickHouse. The repository describes itself as: ClickHouse Java Clients & JDBC Driver. The licence is Apache-2.0.

When your agent uses it

  • StatementSQLTest.testAllowedKeywordAliasesMatchSystemKeywords
  • DatabaseMetaDataTest.testAllTableEnginesFromSystemTableEnginesAreMapped fails

Example prompts

  • “/update-keyword-engine-lists”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Parse the failing test message to extract the list of missing items.
  2. For keywords (StatementSQLTest failure — e.g. ["CURSOR", "DETERMINISTIC", ...])
  3. For engines (DatabaseMetaDataTest failure — e.g. [Paimon, PaimonAzure, ...])

What it can do on your machine

Read from SKILL.md and the folder at commit 67a6b9e. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Update Keyword Engine Lists loads about 457 tokens when it runs. Until then it costs about 80 tokens; SKILL.md has 128 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~80
When it runs · the whole SKILL.md, loaded when a task matches
~457

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Update ALLOWED_KEYWORD_ALIASES in ClickHouseSqlUtils.java and ENGINE_TO_TABLE_TYPE in DatabaseMetaDataImpl.java from failing test output. Use when StatementSQLTest.testAllowedKeywordAliasesMatchSystemKeywords or DatabaseMetaDataTest.testAllTableEnginesFromSystemTableEnginesAreMapped fails.

Update keyword and engine lists from test failures

Files

Keywords: jdbc-v2/src/main/java/com/clickhouse/jdbc/internal/parser/javacc/ClickHouseSqlUtils.java — initAllowedKeywordAliases(), append after the last // Appended comment block.

Engines: jdbc-v2/src/main/java/com/clickhouse/jdbc/metadata/DatabaseMetaDataImpl.java — ENGINE_TO_TABLE_TYPE static block, insert a new group before // Special.

Steps

  1. Parse the failing test message to extract the list of missing items.

  2. For keywords (StatementSQLTest failure — e.g. ["CURSOR", "DETERMINISTIC", ...]): Append a new dated comment + entries at the end of buildKeywordSet(...), after the last existing // Appended block:

    java
    // Appended MM/DD/YYYY
"KEYWORD1", "KEYWORD2", ...

    The previous entry must have a trailing comma. Keep alphabetical order within the new block.

  3. For engines (DatabaseMetaDataTest failure — e.g. [Paimon, PaimonAzure, ...]): Add a new named group before // Special in the static block:

    java
    // <GroupName> (appended MM/DD/YYYY)
map.put("Engine1", TableType.REMOTE_TABLE.getTypeName());

    Choose TableType by analogy:

    • External storage (S3/Azure/HDFS variants, lake formats) → REMOTE_TABLE
    • MergeTree family or local engines → TABLE

Output

After editing, output this git commit command:

git commit -m "jdbc-v2: update <keywords|engines|keywords and engines> in JDBC"
