Lisa Integration Test

Apply Lisa templates to a downstream project and verify it works end-to-end. If anything breaks, fix the upstream templates in Lisa and retry until the project passes all checks.

This must be run FROM the Lisa repository directory.

Prerequisites

• Running from the Lisa repo (has src/core/lisa.ts)
• The target project's working directory is clean (no uncommitted changes)

Instructions

Step 1: Validate Environment

1. Confirm running from Lisa by checking for src/core/lisa.ts
2. Extract project path from $ARGUMENTS. If not provided, ask the user.
3. Validate the project path exists and has at least one project marker:
   • package.json (Node/Bun/TypeScript projects)
   • Gemfile or config/application.rb (Rails projects)
4. Check the project's working directory is clean: git -C <project-path> status --porcelain
   • If dirty, tell the user and stop: "The project has uncommitted changes. Please commit or stash them first."

Step 2: Record Baseline

Before applying Lisa, record the project's current state:

1. Run git -C <project-path> log --oneline -1 to note the current HEAD
2. Note the project's branch and whether there's an open PR: git -C <project-path> branch --show-current

Step 3: Apply Lisa

Run from the Lisa directory:

bun run dev <project-path>

If Lisa fails, report the error and stop.

Step 4: Check What Changed

Run git -C <project-path> status --short to see what Lisa modified.

If nothing changed, report "Lisa applied cleanly with no changes" and stop.

Step 5: Verify the Project

Run the project's verification commands in order. Stop at the first failure:

1. Typecheck: cd <project-path> && bun run typecheck (or npm run typecheck based on package manager)
2. Lint: cd <project-path> && bun run lint (or equivalent)
3. Test: cd <project-path> && bun run test (or equivalent)

Determine the package manager by checking which lockfile exists:

• bun.lockb → bun
• pnpm-lock.yaml → pnpm
• yarn.lock → yarn
• package-lock.json → npm

Step 6: Handle Failures

If any verification step fails:

1. Diagnose: Analyze the error output to determine root cause
2. Determine fix location:
   • If the fix belongs in Lisa templates (the upstream change broke something), fix it in Lisa and go to Step 6a
   • If the fix belongs in the project's *.local.* files (project-specific override needed), fix it in the project and go to Step 6b
3. Report what failed and what you're fixing

Step 6a: Fix Upstream in Lisa

1. Make the fix in the Lisa template files
2. Run Lisa's own checks: bun run typecheck && bun run lint && bun run test
3. If Lisa's checks pass, go back to Step 3 (re-apply Lisa to the project)
4. If Lisa's checks fail, fix those too, then retry

Step 6b: Fix in Project Local Files

1. Make the fix in the project's local override files (e.g., tsconfig.local.json, eslint.config.local.ts, vitest.config.local.ts, jest.config.local.ts)
2. Go to Step 5 (re-verify the project)

Step 7: Commit and Push

Once all verification passes:

1. Stage all changes in the project: git -C <project-path> add <changed-files>
2. Commit with message: chore: apply Lisa <version> templates
3. Push to the project's remote
4. If upstream Lisa changes were made, commit and push those too

Step 8: Report Results

Output a summary:

## Lisa Integration Test: PASSED

**Project:** <project-path>
**Lisa version:** <version>
**Branch:** <branch>

### Changes Applied
- <list of changed files>

### Verification
- Typecheck: PASSED
- Lint: PASSED
- Tests: PASSED

### Upstream Fixes (if any)
- <list of Lisa template fixes made>

### Commits
- <project-commit-hash> chore: apply Lisa <version> templates
- <lisa-commit-hash> fix: <description> (if upstream fixes were needed)

Important Notes

• Never skip verification — the whole point is proving it works empirically
• Fix upstream when possible — if Lisa broke something, fix the template, not the project
• Use local overrides for project-specific needs — tsconfig.local.json, eslint.config.local.ts, etc.
• Retry loop is bounded — if you've tried 3 fix-and-retry cycles without success, stop and report the situation to the user
• Preserve project conventions — check the project's commit message style before committing
