# Expert-exposure profile: every memory_* read + write primitive plus
# `sync` (event log) are surfaced as MCP tools. The agent picks whatever
# it needs — finest granularity, no opinion enforced beyond the
# wikilink-uniqueness gate.
#
# **No `ingest` tool.** Cold-path R-M-W in expert mode is owned by the
# host agent (Claude Code, with the `reme-expert` SKILL loaded), not by
# reme2's internal ReActAgent. The reme-expert plugin spawns a
# `reme-distiller` subagent at SessionEnd to handle distillation in its
# own context window, using the same memory_* primitives.
#
# Use when you want the agent to manage memory directly with full
# control. For an opinionated minimal surface (where reme2's internal
# Ingestor owns R-M-W), see ./service.yaml.

  - backend: base
    name: sync
    description: |
      Hot-path event sync: idempotent upsert of an event FOLDER under
      `events/{date}/{name}/`. The folder contains the index `{name}.md`
      (Event schema, frontmatter + narrative + Materials footer) plus
      any raw materials you pass — conversation snippets, tool outputs,
      data dumps. The watcher indexes everything inside.

      CONTINUITY MODEL: pick a stable `name` per logical thread and
      call `sync` repeatedly through the task. Each call extends the
      same folder:
        * new `content` → appended under a `## Update — {iso}` section
        * new `materials` → siblings (auto-suffix on filename collision)
        * `topics` + `tags` merged (union) into frontmatter
        * Materials footer regenerated to list every artifact in the folder

      First call (folder doesn't exist) → CREATE; subsequent calls with
      the same `name` while the event is `status: active` → APPEND.
      If the event is `status: distilled` / `archived`, `sync` REFUSES
      and returns a `suggested_name` so you start a fresh thread
      instead of mutating prior cognition.

      Zero LLM cost. Call CONTINUOUSLY through a task as facts land,
      and especially at PreCompact to dump verbose raw text into
      `materials` before context truncation loses it. The folder is
      the unit `ingest` later reads from.
