# add_sprint_note [SUPPORT] Add an ephemeral note to the current session's scratch pad. Use for constraints, blockers, working assumptions valid only this session. Notes are auto-deleted when the session closes. Pass note_kind='thinking' for a thinking_sync (HOOKS_DEBUG_STATE) note: a structured snapshot of the reasoning state (what was tried, what failed, current confirmed state) that the dashboard renders with a distinct icon. Intended for Claude's client-side thinking_sync post-tool-call hook, which extracts the extended-thinking scratchpad and persists it here so debugging state survives across turns and into the next session brief. Persistent-state disclosure: on hosted Meridian, supplied text and project/session metadata are sent to and stored in Meridian's service; self-hosted deployments keep them in the configured local SQLite/Postgres database. This data is visible in the dashboard/API and later project context or handoffs. Delete individual tasks, notes, or decisions where supported, or delete the project/account using the documented controls. Do not include secrets.

The data is automatically deleted when the session ends, making it reversible and non-persistent. It supports coordination and debugging within a session but does not modify permanent data structures, execute commands, or cause irreversible changes. From the tool's own definition: "Tool description explicitly states 'Add an ephemeral note' and 'notes are auto-deleted when the session closes', indicating creation of temporary data structures that are reversible and session-scoped."

Every call changes real data in your Meridian environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
