- second-brain-changed-my-mindundefined-ui/second-brain-osTrace where the user's recorded position on something has shifted: superseded claims, contradictions between sources of different dates, and what evidence moved them. Use this skill when the user asks what they have changed their mind about, how their thinking on a topic developed, what they used to believe, or wants a quarterly look back at their own positions. Do NOT use for finding contradictions between sources with no time dimension, or for a current-state answer.OtherNo warnings★ 1.2K↓ —
- gate-checkundefined-ui/second-brain-osFind the decisions in a pipeline that do not need the expensive model and propose the gate for each: a rule, a classic classifier, or a small model, with fail-closed routing.

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

- evals-bootstrapundefined-ui/second-brain-osScaffold a first eval suite for an agent: mine real failures into cases, write behavioural checks over traces, and generate the runner.
