This skill provides Archon decentralized identity operations and helper scripts for local node management, DID creation, credential issuance, and vault operations using public and local nodes (`https://archon.technology`, `http://localhost:4226`). It requires `ARCHON_PASSPHRASE`, executes shell commands like `npx @didcid/keymaster`, and performs `curl` network calls.

This skill implements a SQLite-based agent memory system with shell helpers for logging, semantic search, backups, and identity management. It reads `HEXMEM_DB`/`~/clawd/hexmem/hexmem.db` and `~/.config/hex/archon`, requires `ARCHON_PASSPHRASE`, and uploads full DB backups via `npx @didcid/keymaster add-vault-item` to `https://archon.technology`.
