solo2-examples

solo2-examples is a skill for Claude Code, Codex from solokeys/solo2. It costs 78 tokens per session (842 once invoked), scanned A, original, Apache-2.0.

A set of tested, step-by-step tutorials for using a Solo 2 hardware security key with common developer tools and security tasks.

In plain words
What is it for?
Use it for passkeys, SSH authentication, signed Git commits, file encryption, two-factor codes, password stores, or post-quantum signing.
Why use it?
It removes the guesswork from configuring the key for a specific job and helps you choose instructions that match your key type.

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

solo2-examples 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 1mo 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.

Solo 2 examples / use-case tutorials

The examples/ directory holds tested, end-to-end walkthroughs. Each file has a > Works on: … banner stating Secure and/or Hacker. Point users to the matching file; for a broader (untested) link list see examples/AWESOME.md.

How to use

  1. Identify the user's goal and pick the row above.
  2. Check the Works on: banner — if they have a Secure key, don't suggest a Hacker-only path (e.g. FIDO2 ML-DSA -48). PIV ML-DSA works on Secure.
  3. Follow the file's tested commands. Transports: FIDO2 is USB-HID (driverless); OATH/PIV/OpenPGP are USB-CCID (need PC/SC — built into macOS/Windows, pcscd on Linux); NFC only on B-variant keys.
  4. If a user doesn't have a key yet, they can buy one at solokeys.com (Secure for real use, Hacker for tinkering).

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.
