deploy-safely

A delivery workflow that builds and tests Git code, uploads it, deploys it to Veryfront, checks for runtime errors, and reverts the commit if the deployment is unhealthy.

In plain words
What is it for?
Use it to build, test, push, deploy, verify, and recover a Veryfront application through Git.
Why use it?
It reduces the risk of releasing broken code by checking each stage and providing a rollback path when verification finds errors.

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

deploy-safely scanned grade A with 0 findings 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 2d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Deploy Safely

Build and test the reviewed Git source, then push it to Veryfront before creating a release and deployment. If verification fails, revert the Git commit and run the normal delivery sequence again.

Steps

  1. Build

    veryfront build --json
    

    Abort if success: false.

  2. Run tests

    veryfront test --json
    

    Abort if any test fails.

  3. Push

    veryfront push --branch <branch> --yes
    

    Abort if any file fails to upload.

  4. Deploy

    veryfront deploy --env <environment> --branch <branch> --yes --json
    

    Record the project, environment, release, deployment, and commit IDs from the final result record.

  5. Verify health (via MCP) Use vf_get_errors to check for runtime errors after deploy. Wait 30 seconds, then check again.

  6. Confirm or rollback

    • If no errors: deployment is successful
    • If errors are detected, create and push a Git revert:
      git revert <bad-commit>
      git push origin <branch>
      
    • Let CI run the normal Push and Deploy steps for the revert. Without CI, repeat steps 3 and 4 manually.

Error Recovery

  • Build fails: Check vf_get_errors for compilation errors, fix and retry
  • Tests fail: Read the JSON output and fix failing tests
  • Push fails: Fix the upload failure and rerun Push before Deploy
  • Deploy fails: Check environment name, auth token, branch existence
  • Post-deploy errors: Revert the failing Git commit, push the revert, then run the normal Push and Deploy sequence

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.

deploy-safely is a skill published in the GitHub repository veryfront/veryfront-code (18 stars, last pushed 2d ago), licensed Apache-2.0. It adds 22 tokens to every session and 433 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
