high confidencePurpose & Capability
Name and description (Ed25519 signing for Moltbook posts) match the included scripts and SKILL.md. Required binaries (openssl, base64) are reasonable and are the ones the scripts use. No unrelated credentials or services are requested.
Instruction Scope
SKILL.md and scripts confine themselves to key generation, signing, and verification workflows. They read/write keys under ~/.config/moltbook or paths given by optional env vars and use temporary files for signing/verification. There are no instructions to read unrelated system files, harvest environment variables, or transmit secrets to remote endpoints.
Install Mechanism
This is an instruction-only skill with bundled shell scripts; there is no network download or installer. Scripts rely on standard system tools (openssl, base64, mktemp, grep, date).
Credentials
No required environment variables or credentials are declared. The scripts accept optional MOLTBOOK_SIGNING_KEY and MOLTBOOK_SIGNING_PUBKEY to override key paths — a reasonable and proportionate convenience. No broad or unrelated secrets are requested.
Persistence & Privilege
Skill is not always-enabled, is user-invocable, and does not modify other skills or system-wide configuration. It stores keys only under the user's config directory (or an overridden path).
Assessment
This skill appears to do exactly what it says: generate an Ed25519 keypair locally and sign posts with it. Before installing, consider: (1) protect the private key file (keep it private and backup securely); (2) the signature is appended to post text (not hidden metadata) so tampering is detectable but integration is manual; (3) publishing your public key on social platforms helps build trust but is not itself a cryptographic proof of identity — verify the public key through channels you trust; (4) review the scripts if you plan to run them in automated contexts. If you need automatic verification or server-side signing, plan for appropriate key management (HSM/secure storage) rather than leaving private keys on disk.Like a lobster shell, security has layers — review code before you run it.
