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.

index-doctor	Index diagnosis: inspect URLs via GSC URL Inspection API, diagnose 15+ coverage states, auto-fix and submit to Bing.

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.

Command	Description
/ship	Pre-deploy scorecard. Runs 6 auditors, scores 5 categories
/seo	SEO audit (63 rules) + AI visibility checks (bot access, snippet restrictions, schema)
/secure	Secret scanning + OWASP patterns + npm audit
/perf	Lighthouse + bundle size
/review	Code review with confidence-scored findings
/health	Production health check
/codex	Generate a compact codebase index (routes, schema, components, lib) to save AI tokens
/content	Readability + keyword density analysis
/bundle	Bundle size tracking
/profile	Static analysis for backend anti-patterns
/deps	Unused/outdated dependency detection
/redirects	Redirect chain/loop detection
/revise-claude-md	Update CLAUDE.md with session learnings
/brainstorm	Deprecated alias → use the brainstorming skill
/write-plan	Deprecated alias → use the writing-plans skill
/execute-plan	Deprecated alias → use the executing-plans skill

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.

Build	/execute-plan	Working code on a feature branch
Test	TDD skill	Passing test suite
Review	/review + /secure	Review report, security scan
Ship	/ship + /deploy	Scorecard + production deploy
Verify	/canary	Post-deploy health verification
Reflect	/retro + /learn	Retrospective + saved learnings

Run /sprint to follow the full pipeline, or run individual phases as needed.

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.

The SEO scanner checks 63 rules across three layers:

• SEO (39 rules): meta tags, canonicals, heading hierarchy, alt text, OG tags, sitemap, robots.txt, structured data, analytics detection, cross-page duplicate titles/descriptions, orphan page detection, canonical conflicts, thin content, internal linking
• GEO (20 rules): AI search visibility signals. Does robots.txt block GPTBot/PerplexityBot/ClaudeBot? Do nosnippet/max-snippet directives restrict AI citation eligibility? Is there llms.txt for AI discovery? Does structured data exist for AI extraction? These are verifiable technical signals, not ranking factor guesses.
• AEO (4 rules): answer engine schema checks. FAQPage, HowTo, speakable, Article/BlogPosting. These are the structured data types that enable featured snippets and voice results. We check presence, not SERP performance.

Beyond the scanner, Ultraship connects to real APIs: GSC URL Inspection (actual index status), GA4 (actual AI referral traffic from ChatGPT/Perplexity/Copilot), Bing Webmaster (crawl status, IndexNow). Data-driven analysis, not estimates.

Dogfooding

/ship results on SaveMRR (Hono + React + Drizzle pnpm monorepo, 5 packages, 41 routes):

	Backend + Dashboard	Landing (29 pages)
SEO + AI Visibility	63	52
Security	100	100
Code Quality	70	67
Bundle Size	100	92
Overall	83	78

227 findings: 1 N+1 query, 33 unused deps (dead shadcn/ui wrappers via import graph), 153 SEO issues, 1 memory leak, 1 heavy dep.

Security

All tools use execFileSync with array args (no shell interpolation). HTTP tools import tools/lib/security.mjs for SSRF protection (blocks private IPs, cloud metadata, non-HTTP schemes). 10MB file read cap. 5MB response cap. Secret values redacted in output. Zero telemetry.

See SECURITY.md.
