- harness-auditundefined-ui/second-brain-osAudit an agent's harness against the four rings: containment, guides, sensors, permissions.

Analysis plus an optional baseline scaffold. Do NOT use for auditing context layout (context-audit) or for building eval suites (evals-bootstrap).ProductivityNo warnings★ 1.2K↓ —

- second-brain-renameundefined-ui/second-brain-osRename a page safely: update the file, fix every inbound wikilink, add the old name as an alias, and log it.

- planUpdatedhashgraph-online/awesome-codex-pluginsPlan future work, investigate before building, research a topic, or compare the alternatives for a choice. Takes optional free text.
