@byterover/byterover

ByteRover context engine plugin for OpenClaw, mono build. It recalls curated knowledge in-process from ByteRover's centralized data directory and exposes brv_record so the agent can write durable memory through a first-class tool.

What It Does

1. assemble runs in-process recall and injects <byterover-context> when matching topics exist.
2. assemble always injects <byterover-curate-guidance> so the agent knows when and how to preserve durable knowledge.
3. The plugin registers brv_record; there is no afterTurn auto-curate flow.

This follows ByteRover v4 skill behavior: query before thinking, then curate only knowledge with durable value after implementation.

What To Record

Record:

• Decisions and the reasoning behind them.
• Rules, conventions, and preferences worth pinning.
• Bug symptoms, root causes, and fixes.
• Non-obvious gotchas, constraints, or reusable workflow/design patterns.
• Facts the user explicitly asked the agent to remember.
• Durable new results produced after ByteRover recall had no relevant topic for the user's question.

Skip:

• General explanations, definitions, summaries, or facts the user did not ask the agent to remember.
• Details already obvious from code, git history, or files just edited.
• Pure acknowledgements, greetings, or clarifying questions with no durable content.
• Knowledge already covered by retrieved ByteRover context.
• Unrelated retrieved context; do not save irrelevant hits just because recall returned them.

Prerequisites

• OpenClaw with plugin context engine support.
• Node.js 22+.
• A sibling byterover-mono checkout for local build and tests, because @byterover/core is bundled at build time.

By default the build reads:

../byterover-mono/packages/core/src/index.ts

Override that path with BYTEROVER_MONO_CORE when needed. The published runtime bundle is standalone and does not require the brv CLI at runtime.

Quick Start

Install from the package registry:

openclaw plugins install @byterover/byterover
openclaw config set plugins.slots.contextEngine byterover

For local development:

cd /path/to/brv-openclaw-plugin
npm install
npm run build
openclaw plugins install --link /path/to/brv-openclaw-plugin
openclaw config set plugins.slots.contextEngine byterover

OpenClaw's install validator expects compiled runtime output at dist/index.js, so rebuild before linking after source edits.

Configuration

Configure the plugin through plugins.entries.byterover.config:

{
  "plugins": {
    "slots": {
      "contextEngine": "byterover"
    },
    "entries": {
      "byterover": {
        "enabled": true,
        "config": {
          "cwd": "/path/to/your/project",
          "recallLimit": 5
        }
      }
    }
  }
}

How It Works

assemble

Before each model call, the engine extracts the latest user query, resolves the workspace's ByteRover context tree, searches it through @byterover/core, and injects matching topic HTML inside <byterover-context>.

The same system-prompt addition always includes <byterover-curate-guidance>. That guidance tells the agent to call brv_record only for durable memory, matching the v4 skill state in byterover-mono.

brv_record

The plugin registers a first-class agent tool named brv_record. The agent authors one <bv-topic> HTML document and passes it to the tool with a slash-separated topic path. The tool writes through @byterover/core in-process.

ingest

ingest is intentionally a no-op. Mono recording is explicit through brv_record; the plugin does not batch-curate every turn.

compact

ByteRover does not own compaction. ownsCompaction is false, so the runtime keeps its normal compaction behavior.

Development

npm install
npm run typecheck
npm test
npm run build

Tests resolve @byterover/core from the sibling mono checkout's built dist:

../byterover-mono/packages/core/dist/index.js

Override that with BYTEROVER_MONO_CORE_DIST when needed.
