deploy

deploy is a skill for Claude Code from Houseofmvps/ultraship. It costs 33 tokens per session (3,721 once invoked), scanned A, original, MIT.

A deployment workflow that checks a project before sending it to its hosting platform. Deployment means making the project available in its target environment.

In plain words
What is it for?
Use it to identify the deployment target, validate configuration, check database migrations, run a shipping audit, and deploy through Git or a platform command-line tool.
Why use it?
It catches missing environment settings, migration risks, bundle-size problems, and other pre-deployment issues before release.

Skill for Claude Code

Written for Claude Code: argument-hint in frontmatter.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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 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 8d 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.

Deploy

Full pre-flight validation → deploy pipeline. Closes the audit-to-production loop.

Process

Step 1: Detect Deploy Target

Check project for deploy configuration:

  • vercel.json or .vercel/ → Vercel (git push)
  • railway.toml or railway.json → Railway
  • fly.toml → Fly.io
  • wrangler.toml → Cloudflare Workers
  • .github/workflows/ with deploy steps → CI/CD pipeline
  • Dockerfile → Container-based deploy
  • None found → ask user for deploy target

Step 2: Pre-Flight Checks

Run these checks BEFORE deploying (fail fast):

2a. Environment Validation

node ${CLAUDE_PLUGIN_ROOT}/tools/env-validator.mjs <project-directory>

If deploy_ready: false → STOP. Show missing vars. Do not deploy.

2b. Migration Safety

node ${CLAUDE_PLUGIN_ROOT}/tools/migration-checker.mjs <project-directory>

If deploy_safe: false → WARN. Show pending migrations. Ask user to confirm.

If a Supabase MCP server is connected (check your available tools for supabase), verify migration state against the actual database before deploying, not just the local migration files: list applied migrations and confirm the pending ones aren't already applied or in conflict. This catches the "migration ran on the dashboard but not in the repo" drift that breaks deploys.

If there are pending migrations, verify they are reversible:

  • For Drizzle: check that corresponding down SQL or rollback logic exists
  • For Prisma: confirm prisma migrate resolve can undo the migration
  • For Knex: verify the down() function exists and is not empty
  • If the migration is destructive (dropping columns, renaming tables, deleting data) and has no rollback path → STOP. This is not safe to deploy without a manual rollback plan.

2c. Bundle Size Check

node ${CLAUDE_PLUGIN_ROOT}/tools/bundle-tracker.mjs <project-directory> --save

If bundle grew >50KB since last check → WARN. Show diff.

2d. Git Status Check for uncommitted changes:

git status --porcelain

If dirty working tree → WARN. Suggest committing first.

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 is a skill published in the GitHub repository Houseofmvps/ultraship (121 stars, last pushed 2mo ago), licensed MIT. It adds 33 tokens to every session and 3,721 once invoked, about $0.0002 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.
