…, release-cel2sql) The Spark dialect work (#117), the v3.7.0/v3.7.1 release flow, and the 5+ CEL feature PRs in the recent history are all heavily procedural, multi-file, and easy to mess up in subtle ways. Captures each pattern as a Claude Code skill following the discipline established by skill-authoring (#118): - add-sql-dialect (~25 file touches in lockstep): SKILL.md + dialect-method matrix across the 6 existing dialects, exhaustive touchpoints checklist, check_testcase_coverage.py script (verifies every WantSQL has the new dialect or a SkipDialect reason), and a gen_expected_sql.go.tmpl build-tagged template that prints actual SQL for every shared test case. - add-cel-feature (5+ recent PRs): SKILL.md + converter-file-map (which file owns which CEL surface area) + dialect-method-checklist (steps when adding a method to dialect.Dialect, with a worked WriteEpochExtract example). Reuses check_testcase_coverage.py. - release-cel2sql (every release): SKILL.md + semver-decision tree with the SIV /v4 caveat + prepare_release.py script that splits [Unreleased] into a versioned section dated today and prints the branch/commit/tag commands. Errors out cleanly when [Unreleased] is empty (the v3.6.0 → v3.7.0 backfill footgun is now caught). All three pass `python .claude/skills/skill-authoring/scripts/lint_skill.py` with 0 errors / 0 warnings. check_testcase_coverage.py self-tests correctly across all six existing dialects (spark, duckdb, postgresql, bigquery: full coverage; mysql, sqlite: real gaps in array/comprehension tests). prepare_release.py self-tests against a synthetic CHANGELOG.md. Branched off feat/add-skill-authoring-skill (#118) so the linter is locally available; the skill-authoring content is unchanged from #118 so this branch needs no rebase touch-ups beyond the standard merge once #118 lands.

Summary
Re-targets #119 onto
main. The original PR was stacked onfeat/add-skill-authoring-skill(which became #118), and after #118 was squash-merged into main, GitHub merged #119's content into the now-stale branch instead of into main. Net result:skill-authoring/is on main, butadd-sql-dialect/,add-cel-feature/, andrelease-cel2sql/are not.This PR cherry-picks the three-skills commit onto a fresh branch off main. Content is identical to #119.
