Chainletter CredCLI

This skill appears to do what it says (generate, upload, and blockchain-stamp credentials), but it requires installing an external npm package, a Chainletter account/token, and network access to Chainletter/Clstamp domains. Important things to consider before installing or allowing the agent to use it: 1) Verify the @credcli/cli npm package and its publisher before running the global install; prefer installing in an isolated environment or reviewing the package source. 2) The workflow includes non-interactive 'send --yes' and 'stamp' commands that will upload files and perform irreversible blockchain stamping — require an explicit human confirmation step before those commands run. 3) Avoid changing an allowlist to 'All' unless you understand the broader network implications; instead add only the required domains if possible. 4) Be cautious about where the Chainletter token is stored after 'credcli register' and who or what has access to it; the token scopes tenant/group access. 5) If you do not want the agent to perform uploads/stamps autonomously, disable autonomous invocation for this skill or require manual approvals. If you want a safer test, run everything locally with dummy data and review outputs before issuing real sends/stamps.
