ssl-check is a command for Claude Code from fatihkan/badi. It costs 0 tokens per session (285 once invoked), scanned A, original, MIT.

An SSL certificate and TLS check for a website domain. It reports whether the certificate is valid, which TLS version is used, and whether the encryption methods are strong.

In plain words
What is it for?
Use it to check a domain's certificate expiry, supported TLS version, cipher strength, and covered domain names.
Why use it?
It helps find expired certificates, outdated TLS versions, and weak encryption before they cause connection failures or security problems.

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

ssl-check 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 today.

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

SSL certificate analysis command. Checks certificate validity, TLS version, and cipher strength for a domain.

Required Tools

  • Bash (badi ssl command invocation)

Procedure

Step 1: Domain Check

Take the domain from the user. If invoked without an argument, ask which domain to test.

Step 2: Run the Badi CLI

badi ssl [domain]

Example:

badi ssl example.com
badi ssl github.com

Step 3: Interpret the Result

Points to watch while relaying the output:

  • Expiry < 30 days: Warn the user, suggest renewal planning
  • TLS < 1.2: Security hole, upgrade mandatory
  • Weak ciphers (RC4, 3DES, MD5): Suggest an update
  • SAN check: Show the user the domain list

Step 4: Suggest Follow-ups

Depending on the situation:

  • Expiry near: "Shall we write a Let's Encrypt auto-renew script?"
  • Weak ciphers: "Need an Nginx/Apache config example?"
  • All OK: "Want a DNS check with badi dns [domain]?"

Example Usage

User: /ssl-check example.com
Assistant: [runs badi ssl example.com, summarizes the output]

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.
