+description: Use Fidget Spinner as the local system of record for structured research and optimization work. Read health, schema, and frontier state first; prefer cheap off-path DAG writes; reserve atomic experiment closure for benchmarked core-path work.

+
+# Fidget Spinner
+
+Use this skill when working inside a project initialized with Fidget Spinner or
+when the task is to inspect or mutate the project DAG through the packaged MCP.
+
+Start every session by reading `system.health`.
+
+If the session is unbound, or bound to the wrong repo, call `project.bind`
+with the target project root or any nested path inside that project.
+
+Then read:
+
+- `project.status`
+- `project.schema`
+- `frontier.list`
+- `frontier.status` for the active frontier
+
+If you need more context, pull it from:
+
+- `node.list`
+- `node.read`
+
+## Posture
+
+- the DAG is canonical truth
+- frontier state is a derived projection
+- project payload validation is warning-heavy at ingest
+- annotations are sidecar and hidden by default
+
+## Choose The Cheapest Tool
+
+- `research.record` for exploratory work, design notes, dead ends, and enabling ideas
+- `note.quick` for terse state pushes
+- `node.annotate` for scratch text that should stay off the main path
+- `change.record` before core-path work
+- `experiment.close` only when you have checkpoint, measured result, note, and verdict
+- `node.archive` to hide stale detritus without deleting evidence
+- `node.create` only as a true escape hatch
+
+## Discipline
+
+1. Pull context from the DAG, not from sprawling prompt prose.
+2. Prefer off-path records unless the work directly advances or judges the frontier.
+3. Do not let critical operational truth live only in annotations.
+4. If the MCP behaves oddly or resumes after interruption, inspect `system.health`
+   and `system.telemetry` before pushing further.
+5. Keep fetches narrow by default; widen only when stale or archived context is
+   actually needed.
+6. When the task becomes a true indefinite optimization push, pair this skill
+   with `frontier-loop`.
