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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 32 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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.

Index

File Use case Works on Key tools
FIDO.md FIDO2/WebAuthn passkeys, hmac-secret, the COSE algorithms Secure + Hacker browser, python-fido2, solo2, libfido2
SSH.md SSH keys bound to the token (ed25519-sk/ecdsa-sk) Secure + Hacker OpenSSH ≥ 8.2
GIT.md Signing git commits (and optional push auth) with the key Secure + Hacker git, SSH-signing
AGE.md File/disk encryption, touch-to-decrypt Secure + Hacker age + age-plugin-fido2-hmac
OTP.md TOTP/HOTP 2FA codes generated on the key Secure + Hacker solo2 app oath, oath-toolkit
PASS.md Password stores; passkey/2FA for vaults Secure + Hacker pass/passage, Bitwarden/1Password
POST_QUANTUM.md ML-DSA-44 signing — PIV (Secure+Hacker), FIDO2 -48 (Hacker only) mixed (see banner) python-fido2, pyscard, OpenSSL ≥ 3.5, liboqs
TLOG.md Solo as a post-quantum transparency-log witness (ML-DSA cosignature) Secure + Hacker python, filippo.io/mldsa (Go)
AWESOME.md Curated external links by category (PIV/OpenPGP, LUKS, DNSSEC, CA-on-token, …)

Runnable demo scripts for the post-quantum tutorials are under examples/post_quantum/ (pq_fido2_demo.py, pq_piv_demo.py, pq_tlog_witness.py, and the Go verifier tlog_verify/).

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.
