Platform Deploy Validate

Validating Deployment

Run a server-side validation before deploying metadata. Validation surfaces errors without modifying the org and — for production targets — produces a job ID usable with platform-quick-deploy for a fast, test-free deploy.

Capability Resolution

Always prefer sf project deploy validate (prod) or sf project deploy start --dry-run (sandbox/scratch) over the Tooling API directly.

Workflow

Step 1 — Confirm the target org

Classify the org with the gate's classifier — it is the authoritative source of truth (it handles sandbox/scratch markers, trial and Developer Edition hosts, and dev hubs, and returns one of production|sandbox|scratch|trial|devhub|unknown):

bashCopy code
sf org display --target-org <alias> --json | "${CLAUDE_PLUGIN_ROOT}/scripts/sf-deploy-gate" classify

Only production takes the production path (Step 2b); every other result takes the sandbox/scratch path (Step 2a).

Step 2a — Sandbox/Scratch path (dry-run)

bashCopy code
sf project deploy start --dry-run --target-org <alias> --json [scope flags]

Scope flags (use exactly one, not all):

• --source-dir <path> — deploy a directory
• --metadata <Type:Name> — deploy specific components
• --manifest manifest/package.xml — deploy from manifest

Default test level: omit --test-level for sandboxes (defers to org default). Add --test-level RunLocalTests only if the user asks.

Report back: success/failure, components attempted, any errors. No job ID is returned for dry-runs (this is expected).

Step 2b — Production path (validate)

bashCopy code
sf project deploy validate --target-org <alias> --json [scope flags] --test-level RunLocalTests

Production validations REQUIRE a test level. Use RunLocalTests by default; switch to RunSpecifiedTests --tests <ClassName>... if the user has explicitly listed tests.

The response returns a job ID (result.id) valid for 10 days. Persist it for platform-quick-deploy:

bashCopy code
mkdir -p .sfdx
echo '{"jobId":"<id>","createdAt":"<iso8601>","targetOrg":"<alias>","testLevel":"RunLocalTests"}' > .sfdx/last-validation.json

Report:

• Validation result (passed / failed)
• Job ID and 10-day expiry date
• Test results summary (run / passed / failed)
• Recommended next step: platform-quick-deploy with this job ID

Step 3 — Failure triage

If validation fails, parse result.details.componentFailures and result.details.runTestResult.failures and surface:

• Top 5 component errors with full message
• Top 5 test failures with stack
• Suggested fix (component name → likely cause: missing dependency, FLS, syntax, etc.)

Do NOT propose fixes that change unrelated metadata. Stay scoped to what the validation reported.

Rules

• ALWAYS use --json on every CLI call
• NEVER skip validation when targeting Production (do not run sf project deploy start against prod from this skill)
• NEVER use --ignore-errors or --ignore-warnings during validation; those flags belong to actual deploys, not validation
• If the user asks to "deploy to prod" without prior validation, FIRST run validation, THEN hand off to platform-quick-deploy (do not start a regular deploy against prod)
• Persist the validation job ID to .sfdx/last-validation.json so the quick-deploy skill can find it

Output

Always end with:

• ✅ Validation passed → next-step pointer to platform-quick-deploy (with job ID + expiry) OR to platform-metadata-deploy for non-prod
• ❌ Validation failed → categorized error list and suggested next iteration
