staging-validation-phase

staging-validation-phase is a skill for Claude Code from marcusgoll/Spec-Flow. It costs 56 tokens per session (5,429 once invoked), scanned A, original, MIT.

A pre-release checklist for testing a new build in a staging environment, which is a production-like copy used for safe verification. It covers smoke tests, key user actions, data migrations, and rollback checks.

In plain words
What is it for?
It helps validate login, core features, payments, data operations, migrations, and rollback before production approval.
Why use it?
It helps catch serious problems before the release reaches real users and confirms that the deployment can be reversed.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

staging-validation-phase scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 768 lines — stays where its author put it; the contents beside it link to each section on GitHub.

This skill orchestrates the staging validation phase, which occurs after /ship-staging and before /ship-prod in the staging-prod deployment workflow.

Core responsibilities:

  • Run automated smoke tests on staging environment
  • Test critical user flows manually (authentication, core features, payments)
  • Verify data migrations executed successfully
  • Test rollback capability (actual rollback + roll-forward)
  • Document sign-off decision (approve/reject with justification)
  • Update state.yaml with validation results

Inputs: Staging deployment (URL, deployment ID, migration results) Outputs: Validation report, sign-off decision, state.yaml update Expected duration: 30-60 minutes

<quick_start> Execute staging validation in 5 steps:

  1. Run smoke tests - Execute automated smoke test suite on staging URL

    npm run test:smoke -- --url=$STAGING_URL
    

    Verify: homepage loads (200), API health endpoint (200), database connection

  2. Test critical user flows - Manual testing of core functionality

    • Authentication (login, logout, password reset)
    • Primary user workflow (feature-specific)
    • Payment processing (if applicable)
    • Data CRUD operations
  3. Verify data migrations - Check staging database for migration results

    # Connect to staging database
    psql $STAGING_DATABASE_URL -c "SELECT version FROM alembic_version;"
    # Verify tables, columns, constraints match expectations
    
  4. Test rollback capability - Execute actual rollback test

    # Rollback to previous deployment
    vercel rollback $PREVIOUS_DEPLOYMENT_ID
    # Verify previous version is live
    # Roll forward to current deployment
    vercel promote $CURRENT_DEPLOYMENT_ID
    
  5. Document sign-off - Update state.yaml

    manual_gates:
      staging_validation:
        status: approved # or rejected
        approver: "Your Name"
        timestamp: "2025-11-19T10:30:00Z"
        blockers: [] # or list of issues if rejected
    

Key principle: Test as if this is production. All failures must be fixed before production deployment. </quick_start>

<knowledge_requirements> Required understanding before validation:

  • Smoke tests: What automated tests exist, how to run them, what they verify
  • Critical user flows: Which workflows are essential for production (auth, core feature, payments)
  • Data migrations: What schema changes were made, how to verify them
  • Rollback procedure: How to rollback deployment, how to verify previous version, how to roll forward
  • Sign-off criteria: What constitutes approval vs rejection (all tests pass, no blocking bugs)

See deployment-strategy.md in project docs for platform-specific rollback procedures. </knowledge_requirements>

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
