Tools (40)

Each tool is a standalone Node.js script (node tools/<name>.mjs). JSON output. Exit 0 always. No build step.

Auditing

Tool

What it checks

seo-scanner

63 rules: 39 SEO (meta tags, canonicals, headings, OG tags, structured data, sitemap, cross-page duplicate/orphan detection), 20 GEO (AI bot access in robots.txt, snippet restrictions, llms.txt, structured data for AI extraction), 4 AEO (FAQPage/HowTo/speakable schema)

a11y-scanner

WCAG 2.2 A/AA static checks: missing alt text, unlabeled form controls, icon-only buttons, missing lang/title/main, heading order, positive tabindex, zoom disabled, duplicate ids, broken aria references. Zero false positives.

ship-gate

Blocking quality gate — scores all auditors (shared math with /ship), compares to .ultraship/ship-gate.json thresholds, hard-fails on leaked secrets / critical findings, exits 1 on fail. Generates a pre-push hook + GitHub Actions workflow.

secret-scanner

AWS keys, Stripe keys, JWT secrets, database URLs, private keys. Redacts values in output.

vibe-security-scanner

Vibe-Coding Security Sentinel — context secret-scanner misses: server-only secrets behind a NEXT_PUBLIC_/VITE_ prefix, a decoded Supabase service_role key exposed to the client, service_role in a "use client" file, Supabase tables with no RLS. Zero false positives.

eval-scanner

Locates every LLM call site (Anthropic, OpenAI, Gemini, Mistral, Cohere, Ollama, Vercel AI SDK, LangChain) by provider + model id, detects the test runner and whether an eval suite exists. Flags AI features shipping with no evals. Seeds /evals. Zero false positives.

code-profiler

N+1 queries, sync I/O in handlers, unbounded queries, missing indexes, memory leaks, sequential awaits, ReDoS risk

bundle-tracker

JS/CSS/image sizes in build output. Detects heavy deps (moment→dayjs, lodash→native). History for before/after. Monorepo-aware.

dep-doctor

Unused dependencies via import graph analysis (not just grep). Dead wrapper files. Outdated packages.

content-scorer

Flesch-Kincaid readability, keyword density, thin content detection, GEO heading analysis

canary-monitor

Post-deploy canary monitoring: HTTP status, response time, error patterns, baseline regression detection. Auto-saves baselines for future comparison.

retro-analyzer

Sprint retrospective: git velocity, commit patterns (features vs fixes), test health, hot files, shipping cadence. Generates insights and recommendations.

learnings-manager

Project learnings CRUD: save, search, list, prune, export. Structured knowledge that compounds across sessions.

Project Analysis

Tool

What it does

onboard-generator

Commands (16)

Every skill is also a slash command. Claude Code merged commands into skills, so /a11y, /sprint, /pentest, /compete, /canary, /launch, /rescue, /grow, /deploy, /learn, /guard, /retro, /investigate, /cost, /onboard, /architecture, /clone-patterns, /demo, /visual-diff, /release, /seo-strategy and /index-fix all work too — they live in Skills above. The commands below are the remaining dedicated command files.

Skills (43)

Skills are markdown instruction files that shape Claude's behavior during your session. They activate based on context. When you're debugging, Claude uses the debugging skill. When you're building UI, it uses the frontend design skill.

Workflow (19): brainstorming, planning, TDD, implementation, code review, debugging, refactoring, frontend design, API design, data modeling, git workflow, deploy pipeline, release, CLAUDE.md management, verification, browser testing, sprint pipeline, investigation, learnings management

Specialist (12): SEO + AI visibility audit, accessibility audit + auto-fix, deterministic ship-gate, AI eval harness, security audit, penetration testing, performance audit, content quality, code profiling, parallel agent dispatching, safety guardrails, staying current

Growth & Intelligence (12): competitive analysis, launch prep, incident response, growth tracking, cost tracking, onboarding, architecture mapping, pattern analysis, demo readiness, visual regression, canary monitoring, sprint retrospective

Agents (13)

Agents are dispatched by skills to run audits in parallel:

code-reviewer · seo-auditor · seo-strategist · security-auditor · pentest-auditor · perf-auditor · a11y-auditor · browser-verifier · compete-analyzer · launch-auditor · incident-responder · growth-tracker · canary-monitor

MCP Servers (2)

Server

Purpose

Context7

Live library documentation. Fetches current docs for any framework/library.

Playwright

Browser automation. Navigate, screenshot, fill forms, test deployed pages.

Both lazy-start on first use. No background processes.

Optional MCP integrations (detect-if-present)

Ultraship doesn't bundle these (they need your credentials and would slow every install), but several skills use them automatically if you've connected them:

Connect

Sharpens

Sentry

/rescue pulls live production errors and maps stack traces to code instead of guessing the culprit. /canary confirms a post-deploy error spike before recommending rollback.

Vercel

/deploy reads real deployment status, build logs, and which commit is live (not just a single HTTP probe).

Supabase

/deploy verifies migration state against the actual database to catch dashboard-vs-repo drift.

Add them with claude mcp add (or the /plugin browser). When connected, the skills detect the tools and use them; when not, they fall back to the built-in static checks.

Sprint Workflow

Ultraship skills chain into a structured sprint pipeline. Each phase produces artifacts that feed the next.

Safety Guardrails

/guard activates PreToolUse hooks that block destructive commands before they execute:

flowchart LR
    CMD["Claude runs<br/>a command"] --> HOOK["PreToolUse<br/>Hook"]
    HOOK --> CHECK{"Destructive?"}
    CHECK -->|"rm -rf, DROP TABLE,<br/>git push --force,<br/>kubectl delete..."| BLOCK["BLOCKED"]
    CHECK -->|Safe| ALLOW["Allowed"]

    style HOOK fill:#f59e0b,stroke:#d97706,color:#000
    style BLOCK fill:#ef4444,stroke:#dc2626,color:#fff
    style ALLOW fill:#10b981,stroke:#059669,color:#000
  • rm -rf, DROP TABLE, TRUNCATE (data destruction)

  • git push --force, git reset --hard (git history destruction)

  • git clean -f, git checkout . (working directory destruction)

  • kubectl delete, docker system prune (infrastructure destruction)

Optional directory freeze restricts all file edits to a specific path. Explicitly confirmed actions always proceed.

Persistent Memory

Ultraship enforces a memory-first rule at session start. The SessionStart hook detects if you have a MEMORY.md file and instructs Claude to read it before performing any task. Context persists across sessions. No more repeating yourself about project state, deploy status, or decisions already made.

  • If MEMORY.md is found: Claude reads memory files before doing anything

  • If not found: Claude suggests setting up auto-memory for persistent context

No configuration needed. Just install the plugin.
