web-launch-gate

web-launch-gate is a skill for Claude Code, Codex from winstonkoh87/Athena-Public. It costs 0 tokens per session (2,173 once invoked), scanned A, original, MIT.

A mandatory pre-launch checklist for web applications covering security, privacy, and abuse risks. It checks items such as exposed secrets, unsafe logging, and server-side keys appearing in browser code.

In plain words
What is it for?
Use it before deploying a web-facing application to verify secret handling, environment files, frontend code, and other listed launch checks.
Why use it?
It catches blocking problems before a web application is made public. Failed critical checks stop deployment, while warning-level issues are reported for attention.

SkillSpector: 4 findings, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
    Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

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

web-launch-gate 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 10d 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.

Web Launch Gate

Trigger: Activates automatically when deploying any web-facing application. Authority: This gate is MANDATORY. Do not skip items marked 🔴.


Pre-Flight Checklist

Run every item before deploying. Items marked 🔴 are blocking — deployment MUST NOT proceed if they fail. Items marked 🟡 are warnings — flag to the user but don't block.


1. Secrets & Keys

# Check Severity How to Verify
1.1 .env / .env.* is in .gitignore 🔴 Critical grep -n "\.env" .gitignore
1.2 No API keys, tokens, or passwords hardcoded in source 🔴 Critical grep -rn "sk-|sk_live|AKIA|ghp_|glpat-|xoxb-|Bearer [A-Za-z0-9]" --include="*.{ts,js,py,tsx,jsx}" .
1.3 No secrets in console.log, print(), or error responses 🔴 Critical grep -rn "console\.log.*key|console\.log.*secret|console\.log.*token|console\.log.*password" --include="*.{ts,js,tsx,jsx}" .
1.4 All keys loaded from environment variables or secret manager 🔴 Critical Manual review of config/init files
1.5 Frontend code does NOT contain server-side keys 🔴 Critical Check src/, public/, app/ for any process.env.SECRET_* usage that gets bundled client-side. In Next.js, only NEXT_PUBLIC_* vars reach the browser — everything else must stay server-side.

2. Authentication & Authorization

# Check Severity How to Verify
2.1 Auth is implemented if any user data is stored 🔴 Critical Review auth provider setup
2.2 Protected routes/API endpoints require authentication 🔴 Critical Test unauthenticated access to protected endpoints
2.3 JWT verify_jwt is true for edge functions / API routes 🔴 Critical Check supabase/config.toml or middleware config
2.4 RLS (Row Level Security) enabled on all database tables 🔴 Critical SELECT tablename, rowsecurity FROM pg_tables WHERE schemaname = 'public';
2.5 Password minimum length ≥ 8 characters 🟡 Warning Check auth config

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.
