fix(refresh-drizzle-migration): refresh finds stale migrations wherever the generate script runs drizzle-kit - #110
PR #109 shipped the refresh-drizzle-migration skill, which regenerates a branch's stale Drizzle migration after a base merge. It merged while four review threads were still open, and they found real gaps. Step 1 looked for migrations relative to the config file, but drizzle-kit writes them relative to the directory it runs in. So a project whose script runs drizzle-kit generate --config config/drizzle.config.ts had its stale migration left untouched with no warning. The skill could also run a generate script whose npm post hook pushes to a database. And a conflict resolution started outside the skill could discard the head's edit to an existing migration. This PR closes those gaps and tightens the SQL comparison step.
What changed
Step 1 records each config's generate script and the directory drizzle-kit actually runs in. That directory accounts for cd, --filter, --prefix, --cwd and -C. The skill resolves out and --config against it, and stops to ask when two scripts reach one config from different directories. Step 4's direct-binary fallback runs from the same directory.
Step 4 runs the project's script only when the script does nothing but drizzle-kit generate for this config and has no pre or post hook, since npm runs those hooks with the script. Anything else goes to the installed binary, run directly.
resolving-merge-conflicts step 1: when the refresh skill did not start the merge, it first runs the refresh skill's check for head edits to migrations the base already has, and stops on any it finds before taking a side. When the merge drops the head's migration, it skips its own verification run, because the refresh skill runs it after regenerating. That stops a migration-consistency check from failing mid-merge on a gap the refresh is about to close.
Step 5's statement comparison keeps text inside single-quoted, double-quoted and dollar-quoted SQL strings byte-exact, drops -- comments, and trims each statement before stripping its trailing ;. Previously, DEFAULT 'a b' and DEFAULT 'a b' compared as equal.
Step 6 commits any fix for other merge damage before the regenerated migration, so the two don't share a commit.
How to verify
python3 -I tools/verify_skills.py ./skills exits 0 with the same 23 warnings as main.
python3 -m unittest discover -s tools/eval runs 282 tests, OK.
In scratch repos I ran the git commands the new text relies on:
Mid-merge, git diff --name-only --no-renames --diff-filter=MD MERGE_HEAD...HEAD flags a head edit to a base-owned snapshot and leaves the journal alone.
In a nested db/drizzle folder after a hand merge, the same check lists only paths the skill exempts.
The changes went through three review passes. The last found no Critical or Serious problems.
One review comment, raised again in the last pass, asked the skill to stop until the user confirms whether a database already applied the stale migration. I left it out, as on feat(skills): asking to refresh a stale Drizzle migration now runs one checked procedure #109. The skill never touches a database, and its final report already tells the user what happens to such a database.
skills/refresh-drizzle-migration/SKILL.md is now 9,880 bytes, close to the verifier's 10,000-byte threshold. The next addition should move the folder-layout details into references/.
Follow-up to #109's open review threads. Refs #105
Summary by CodeRabbit
Documentation
Clarified how migration refresh handles configuration paths, generation scripts, migration layouts, previously dropped migrations, and comparisons that preserve quoted SQL.
Added guidance for generation prompts or terminal failures, including how to continue after generating files manually.
Expanded merge-conflict instructions for Drizzle metadata and migration files, including checks for flagged paths and when to run migration refresh.
Added guidance to recheck configurations after completion and retry if schema changes are detected.
…actually writes it
- resolve out and --config from the directory the generate script runs drizzle-kit in, and stop when two scripts disagree
- run the package script only when it has no pre or post hook that could push to a database
- check for head edits to base-owned migrations before resolving a standalone Drizzle conflict, and defer done until after regeneration
- keep quoted, dollar-quoted and commented SQL intact in the same-change comparison
- commit fixes for other merge damage before the regenerated migration

Walkthrough
The Drizzle migration refresh instructions now track config execution directories, select generation commands, preserve quoted SQL during comparison, and verify results after completion. The merge-conflict instructions add Drizzle-specific checks and resolution rules. A reference covers generation prompt and timeout failures.
Changes: Drizzle migration workflow
Layer / File(s)
Summary
Config discovery, generation, and prompt handling skills/refresh-drizzle-migration/SKILL.md, skills/refresh-drizzle-migration/references/rename-prompts.md
The instructions record each config’s generate directory and select a package script only when it meets the stated conditions. They direct prompt, TTY, and timeout failures to the reference, which explains how to run generation and resume the workflow. The merge workflow no longer needs to provide a readiness card.
SQL comparison and post-completion verification skills/refresh-drizzle-migration/SKILL.md
The same-change check preserves quoted text while normalizing comments and whitespace outside quoted spans. After done changes files, the workflow probes touched configs and can clean up generated migrations, restore the journal, and rerun checks and completion.
The instructions distinguish rebase and merge handling, add discovery and ownership checks before resolving Drizzle files, and specify how to handle conflicted metadata and migration SQL. They also define when to skip step 4 and when to run the refresh workflow.
bhagyamudgal/skills#109: This PR changes the same refresh and conflict-resolution skills and updates behavior introduced by that PR.
Merge Risk: Moderate · previous review 29d97
The migration refresh workflow can commit a regenerated migration without confirming it matches the schema when the post-done probe fails with an error. The merge-conflict workflow can also send unrelated merges through an unneeded refresh and push. Both are instruction-level gaps with bounded impact, and they are worth fixing before merge.

Explanation
The title names the main change: refresh-drizzle-migration now finds stale migrations wherever the generate script runs drizzle-kit. The objectives describe resolving each Drizzle config's output paths and --config relative to the directory where its generate script runs, which matches the title. The fix prefix fits the bug-fix nature of the change. The title is 108 characters, which is long, but it stays a single clear sentence.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Do not assume the config directory is the generate directory.
A project can invoke drizzle-kit generate --config packages/app/drizzle.config.ts from the repository root without a package script. For out: "./drizzle", this instruction checks packages/app/drizzle instead of the actual root drizzle folder. It can classify the config as untouched and leave its stale migration unrefreshed. When no script establishes the directory, ask the user for the invocation directory.

the PR or default base. Use an established way to pass that target; if the
refresh workflow cannot honor it, stop when its resolved base differs from
MERGE_HEAD rather than proceeding with a mismatched migration classification.
