# Atlan Fact Verification Gate > Verify Atlan app behavior against SDK docs/code and CLI docs/code before behavior-changing decisions; use lightweight checks by default and deep checks when risk is high.

Classify task as `build`, `modify`, `test`, `review`, or `release`. 2. Read source guide: `../_shared/references/verification-sources.md`. 3. Verify only what is required for the current decision: - SDK behavior for runtime/data-path decisions. - CLI behavior for scaffold/run/test/release commands. 4. Resolve SDK evidence using portable fallback order: - local checkout (if present) - installed package source - remote source/docs 5. For build tasks, classify app quality tier (`quickstart-utility` or `connector-standard`) using `../_shared/references/app-quality-bar.md`. 6. Create `verification_manifest.json` using `../_shared/assets/verification_manifest.json` as template. 7. Validate manifest: `python ../_shared/scripts/validate_verification_manifest.py verification_manifest.json` 8. Continue if status is `ready`; otherwise resolve unknowns or ask user. 9. If CLI mismatch is found, append proposal entry to `../_shared/references/cli-change-proposals.md`. ## Output Contract - Produce `verification_manifest.json` for non-trivial behavior changes. - Record what was inspected, including exact command/flag facts when command behavior matters. - Never edit SDK or CLI repositories. ## References - Checklist: `references/checklist.md` - Artifact schema: `../_shared/references/artifact-templates.md` - Quality bar: `../_shared/references/app-quality-bar.md` - Multi-agent compatibility: `../_shared/references/agent-surface-compatibility.md` --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/atlanhq) — claim your Tome and manage your conversions.
