Suspicious
medium confidencePurpose & Capability
The skill's purpose (registering an on‑chain identity, signing transactions, posting/voting) legitimately requires a local keypair, Node.js helpers, and a Chromia node URL. However, the registry metadata provided to the evaluator lists no required env vars or credentials, while the SKILL.md itself declares required env vars (CLAWCHAIN_BRID, CLAWCHAIN_NODE) and a credentials file path (~/.config/clawchain/credentials.json). That mismatch is an incoherence the user should notice.
Instruction Scope
Runtime instructions reference reading/writing a local credentials.json (privKey + pubKey), local helper scripts (keygen.js, register.js, generate-tx.js), and a SOUL.md personality file. Those actions are consistent with signing transactions, but the SKILL.md asserts the private key 'never leaves this file' only if the signing scripts are trustworthy. The skill also instructs submitting signed transaction hex via curl to the configured Chromia node. There is no instruction to access unrelated system files, but the critical scope question is: where do the helper scripts come from and can they be trusted? That is unclear.
Install Mechanism
The skill is instruction‑only (no install spec in registry), yet it lists dependencies (Node.js, npm packages postchain-client and @chromia/ft4) and states helper scripts will be created during setup. The SKILL.md includes curl commands to fetch SKILL.md/HEARTBEAT.md from https://clawchain.ai, but it does not clearly state a vetted source or signed releases for the helper scripts. Downloading and executing helper scripts from an owner‑controlled website (not a well‑known package repo or signed release) increases risk because those scripts perform local signing and would have access to your private key.
Credentials
Requesting a local Chromia keypair file is proportionate to a transaction‑signing skill. However, the registry summary initially reported 'no required env vars' while the SKILL.md declares CLAWCHAIN_BRID and CLAWCHAIN_NODE and a credentials path; that inconsistency reduces transparency. Also, the skill will read a sensitive private key file — this is expected for signing but demands that the helper scripts be auditable and trustworthy.
Persistence & Privilege
The skill is not always:true, does not request elevated system privileges, and only intends to create files under ~/.config/clawchain (helper scripts, credentials.json, SOUL.md). Autonomous invocation is allowed (default) which increases blast radius if the skill is malicious, but that alone is standard and not flagged here.
What to consider before installing
This skill’s functionality (creating a keypair, signing transactions locally, and submitting them to a Chromia node) is coherent — but the SKILL.md is the only code provided and it refers to helper scripts that must be present on disk. Before installing or running it: (1) verify the origin and contents of any helper scripts (keygen.js, register.js, generate-tx.js); do not run them without reviewing the code; (2) prefer generating your keypair with trusted, auditable tools and ensure credentials.json is created locally with chmod 600; (3) avoid pasting your private key anywhere and do not upload credentials to remote hosts; (4) if you must fetch scripts from https://clawchain.ai, inspect the downloaded files and consider running them in a sandboxed environment or container; (5) ask the publisher for a reproducible install method (package repo, signed release, or source repo) and an explanation for the registry vs SKILL.md metadata mismatch. If you cannot audibly verify helper scripts and their provenance, treat the skill as too risky to use with real funds or permanent identities.Like a lobster shell, security has layers — review code before you run it.
