markplane-memory

Structured task-oriented memory for AI agents via Markplane.

This OpenClaw plugin injects Markplane's compressed project state into the agent's system prompt on every turn — no tool calls, no instructions that get lost to compaction. Your agent knows what's in progress, what's blocked, and what's next before it reads a single message.

Why Markplane for agent memory

| Capability | OpenClaw today | With Markplane | |---|---|---| | Structure | Prose daily logs | Typed items with YAML frontmatter | | Compression | MEMORY.md (hand-curated, unbounded) | .context/summary.md (~1000 tokens, generated) | | Retrieval | Vector search over all files | INDEX.md routing — load only relevant items | | Relationships | None (text similarity only) | depends_on, blocks, related, [[ID]] cross-refs | | Status tracking | None | draft → backlog → planned → in-progress → done | | Prioritization | None | critical / high / medium / low with sorted context | | AI tool access | memory_search (semantic) | Full MCP server (query, show, add, update, sync) |

Markplane complements, not replaces, OpenClaw's existing memory:

| System | What it stores | Keep using? | |--------|---------------|-------------| | MEMORY.md | Identity, preferences, curated long-term context | Yes | | memory/YYYY-MM-DD.md | Daily logs, session transcripts | Yes | | .markplane/ | Structured tasks, decisions, project state | New |

Daily logs capture what happened. Markplane captures what needs to happen.

What the plugin does

Injects .context/summary.md into the system prompt via the before_prompt_build hook. The agent sees a ~1000-token project overview on every turn, automatically.
Bundles a SKILL.md that teaches the agent how to use Markplane (item types, MCP tools, what's worth capturing).
Configurable — choose which context files to inject and customize the header.

Quick start

1. Install Markplane

See the Markplane installation guide for options (Homebrew, shell script, pre-built binary, or build from source).

2. Initialize in the OpenClaw workspace

cd ~/.openclaw/workspace
markplane init --name "Agent Memory" --empty

The --empty flag skips starter content (sample tasks, etc.) that would clutter the agent's context with irrelevant onboarding material.

3. Install the plugin

openclaw plugins install @zerowand/markplane-memory

4. Register the MCP server

Add an mcp.servers entry to ~/.openclaw/openclaw.json. The --project flag is required because the gateway's working directory isn't your workspace, so markplane can't auto-discover .markplane/:

{
  "mcp": {
    "servers": {
      "markplane": {
        "command": "markplane",
        "args": ["mcp", "--project", "~/.openclaw/workspace"],
        "transport": "stdio"
      }
    }
  }
}

If your workspace is at a non-default location, replace ~/.openclaw/workspace with your actual agents.defaults.workspace path.

5. Restart the gateway

openclaw gateway restart

If existing chat sessions don't pick up the plugin after restart, send /new to start a fresh session.

Verify it works

1. Ask your agent: "Do you see a Task Memory or Markplane section in your system prompt?" — the agent can confirm it sees the injected context 2. Check that markplane appears in the agent's skills list (ask the agent, or check the Skills page in the web UI) 3. Ask the agent to run markplane_summary to confirm MCP tools are working

Web UI

Markplane includes a local web dashboard — a visual interface for your agent's structured memory. Browse tasks on a kanban board, view the dependency graph, track epic progress, and manage the same items your agent works with:

cd ~/.openclaw/workspace    # or wherever you ran markplane init
markplane serve --open

> Note: Markplane stores data in a .markplane/ directory (hidden by default on macOS/Linux). Use ls -a or enable hidden files in your file manager to see it.

See the Markplane Web UI Guide for details.

How it works

Markplane generates compressed, AI-readable summaries in .markplane/.context/:

summary.md — project overview with active epics, blocked items, priority queue, and metrics (~1000 tokens)
active-work.md — currently in-progress tasks with details
blocked-items.md — items with unresolved dependencies
metrics.md — item counts by status and priority

The plugin reads these files and appends them to the system prompt via the before_prompt_build lifecycle hook. By default, only summary.md is injected. The MCP server provides typed tools for creating and updating items.

Configuration

Configure in ~/.openclaw/openclaw.json under plugins.entries.@zerowand/markplane-memory.config:

| Option | Type | Default | Description | |--------|------|---------|-------------| | contextFiles | string[] | ["summary.md"] | Which .context/ files to inject. Options: summary.md, active-work.md, blocked-items.md, metrics.md | | contextHeader | string | "## Task Memory (Markplane)" | Header text prepended to injected context |

Example — inject both the summary and active work:

{
  "plugins": {
    "entries": {
      "@zerowand/markplane-memory": {
        "config": {
          "contextFiles": ["summary.md", "active-work.md"]
        }
      }
    }
  }
}

Optional: Compaction flush prompt

By default, OpenClaw's pre-compaction flush writes to daily log files. You can extend it to also structure items into Markplane before context is compressed. This overwrites the default flush prompt — review it before applying:

{
  "agents": {
    "defaults": {
      "compaction": {
        "memoryFlush": {
          "enabled": true,
          "systemPrompt": "Session nearing compaction. Store durable memories now. Also use Markplane MCP tools to capture any tasks, decisions, or knowledge worth structuring.",
          "prompt": "Write any lasting notes to memory/YYYY-MM-DD.md. Then use markplane_add to capture any new tasks or decisions, and markplane_update for any status changes. Run markplane_sync when done. Reply with NO_REPLY if nothing to store."
        }
      }
    }
  }
}

Manual setup (without the plugin)

If you prefer not to use the plugin, you can set up Markplane manually. The trade-off: without the plugin, context injection relies on an instruction in AGENTS.md that can be lost during compaction.

1. Install Markplane and run markplane init in your workspace (same as above) 2. Register the MCP server in openclaw.json (same as above) 3. Add to ~/.openclaw/workspace/AGENTS.md:

## Task Memory (Markplane)

This workspace uses Markplane for structured task memory in `.markplane/`.

At the start of each session, read `.markplane/.context/summary.md` to
understand current project state. Use Markplane MCP tools (markplane_query,
markplane_add, markplane_update, markplane_sync) to manage tasks.

When decisions are made or action items identified, capture them as
Markplane items. Always run markplane_sync after changes.

Why the plugin is better: The AGENTS.md instruction lives inside the context window and competes with conversation history during compaction — it can be summarized away. The plugin injects context into the system prompt, outside the conversation history, guaranteed on every turn.

| | Plugin | Manual | |---|---|---| | Install | openclaw plugins install @zerowand/markplane-memory | Edit 2 config files + AGENTS.md | | Context injection | Automatic every turn via before_prompt_build | Relies on AGENTS.md (can be lost to compaction) | | MCP server | Requires mcp.servers config entry | Same | | Compaction flush | Optional memoryFlush config edit | Same | | SKILL.md | Bundled, auto-appears in skill list | Must manually create | | Survives compaction | Yes — system prompt injection is outside conversation history | No — competes with conversation history |
