resume_wave

[SUPPORT] efaa918a — STALE-MANIFEST GATING: check whether a wave run opened by start_wave_run is still safe to resume against the LIVE board before you act on its pinned manifest. Re-queries the board across ALL non-done statuses (pending, todo, in_progress, provisional_complete, indeterminate, failed, skipped, pushed) via build_board_snapshot — NEVER status='pending' alone, which is the exact b763d2ba bug class (a sibling-claimed in_progress item looks like it vanished). Fails CLOSED with SPECIFIC, actionable reasons the moment the live board differs from the pinned manifest in ANY of: revision_hash mismatch (added/removed items, status/dependency/resource/pointer changes — reusing diff_board_snapshots's added/removed/changed_items shape verbatim as resume_delta), an item's wave membership changed, or an item was newly marked blocker_kind='superseded' (its premise was replaced). Optionally also verifies a handoff token: pass goal_token (+ presented_body to additionally check body-hash binding, efaa918a — closes the 2ee0000c gap where a genuine token could be re-attached to an edited body and still verify). Token outcomes keep the four existing distinct meanings from verify_handoff_token (not_found/wrong_project are real spoofing signals; already_consumed/expired usually mean a sibling already acted) PLUS the new body_mismatch (a real spoofing signal — genuine token, edited body). Read-only w.r.t. the wave run itself (does not advance wave_run status — call advance_wave_run_status separately once resumable). Returns {resumable, wave_run_id, status, resume_delta, pinned_revision_hash, live_revision_hash, token_check} on success, or {error, resumable: false, reasons, resume_delta, token_check} naming exactly what is stale. Persistent-state disclosure: on hosted Meridian, supplied text and project/session metadata -- including task log entries, pinned decisions, sprint items, notes, handoff/goal state, and HITL queue items -- are sent to and stored in Meridian's service, in an isolated per-tenant Postgres database (Neon); self-hosted deployments keep the same categories in the configured local SQLite/Postgres database. This data is visible in the dashboard and API, and may resurface in later project context or handoffs. Notes and pinned decisions can be deleted individually; task log entries and sprint items can be deleted via the dashboard/API (not exposed as an agent-facing tool); HITL queue items and handoff state have no per-record delete. Full removal of any of this data is available via project or account deletion, using the documented controls. Do not include secrets. It is categorised as a Write tool in the Meridian MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

resume_wave accepts 3 parameters: goal_token, wave_run_id, presented_body. Required: wave_run_id. The full parameter table on this page comes from the server's own tool schema.

Register the Meridian MCP server in PolicyLayer and add a rule for resume_wave: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Meridian. Nothing to install.

resume_wave is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Yes. Add a rate_limit block to the resume_wave rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

Set action: deny in the PolicyLayer policy for resume_wave. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

resume_wave is provided by the Meridian MCP server (@meridianmcp/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
