cel2sql

Adds new CEL operator, function, macro, or comprehension support to cel2sql across all SQL dialects, touching cel2sql.go visit*, the dialect.Dialect interface, every dialect/<name>/dialect.go, and testcases/<category>_tests.go. Use when wiring a new CEL function (e.g., string.toLowerCase, timestamp.toISOString), a new comprehension form, a new operator overload, or extending the converter to recognise a CEL extension package.

Adds a new SQL dialect to cel2sql by registering its name, implementing the Dialect interface in dialect/<name>/, adding a sibling type provider in <name>/, populating shared test cases in testcases/, and refreshing README.md and CLAUDE.md. Use when adding any new database backend (Trino, Snowflake, ClickHouse, MS SQL, Athena, Oracle) or porting cel2sql to another analytics engine.

Cuts a new cel2sql release by preparing CHANGELOG.md, deciding the semver bump from commit history, opening a release-prep PR, then tagging and pushing after merge to trigger .github/workflows/release.yml. Use when shipping any new patch, minor, or major version of cel2sql.

Authors and reviews agent skills for this repo, enforcing progressive disclosure (metadata → instructions → resources), ≤500-line SKILL.md files, domain-split references, scripts over prose for deterministic work, and specific third-person descriptions. Use when creating a new skill, splitting an oversized SKILL.md, or reviewing an existing skill for structure.
