Atlan App Scaffold Standard

Atlan App Scaffold Standard

When a user asks to create a new app, treat CLI bootstrap as implicit. Do not require users to mention CLI commands.

Workflow

1. Interpret user intent:
   • If request is "create/build/new app" (even without technical detail), trigger this skill first.
2. Resolve app path and slug from user request.
3. Ask clarifying questions when high-impact requirements are missing:
   • Ask 1-3 short questions for business behavior only (input source, expected output, critical constraints).
   • Do not ask users to specify CLI commands or low-level scaffolding details.
   • If unanswered, proceed with sane defaults and state the assumptions.
4. Choose quality tier before implementation:
   • default: quickstart-utility
   • use connector-standard when request requires connector behavior comparable to postgres/redshift patterns.
   • follow ../_shared/references/app-quality-bar.md.
5. Run progressive discovery before coding (no repo-wide sweep):
   • quickstart-utility: read only skill references + one representative quickstart app (main/workflow/activity/pyproject + one e2e test), target <= 12 reads.
   • connector-standard: read skill references + one postgres-style and one redshift-style reference slice, target <= 20 reads.
   • Expand beyond budget only when blocked by missing facts.
   • Do not run recursive wildcard scans (for example full-tree Search(\"**\")) in first pass.
6. Enforce CLI-first bootstrap:
   • Check atlan availability (command -v atlan).
   • If available: use atlan app init -o <app_path> -t generic -y (or -s <sample> when requested).
   • If missing: invoke atlan-cli-install-configure, then continue scaffold.
   • Do not begin by searching for a local atlan-cli repository.
   • Re-verify with command -v atlan && atlan --help.
   • If network/install is blocked, stop and ask the user to enable installation or provide an existing CLI binary path.
7. Verify template/sample choices only when needed:
   • atlan app template list
   • atlan app sample list
8. After scaffold, apply mode-specific structure from references/scaffold-matrix.md:
   • postgres-minimal by default.
   • redshift-custom only when requirements demand custom auth/preflight/miner behavior.
9. If behavior-critical decisions are unclear, run atlan-fact-verification-gate.
10. Continue implementation on scaffolded project files; do not hand-create base tree.
11. Before declaring completion, hand off to atlan-cli-run-test-loop to run at least:

• unit tests
• e2e tests (or record a concrete infrastructure blocker) and summarize results.

Hard Rules

• Do not manually create baseline app skeleton when CLI scaffold is available.
• Do not copy another quickstart folder as a substitute for scaffold.
• Keep SDK/CLI repositories read-only.
• Keep outputs portable; no machine-local absolute paths.
