update-claude-documentation

This is a documentation maintenance skill whose capabilities align with its stated purpose: reading and updating repository markdown files and skill metadata. There are no direct supply-chain or network exfiltration indicators in the provided text. Minor to moderate risks: (1) the mandatory use of an unspecified 'Superpowers plugin' (trust depends on that plugin's provenance and permissions), and (2) the enforced automatic updating of MEMORY.md and NEXT_FEATURES.md at every session — if performed without human review or secret-sanitization, this could accidentally expose internal details or credentials in repo docs. Recommend: require human review/approval before committing updates, add explicit redaction/sanitization steps for MEMORY.md, and document/trust-evaluate the Superpowers plugin before enabling it.
