agendum

Project memory and scoping engine for AI coding agents.

AI coding agents are stateless — they forget between sessions, lose decisions, and have no way to scope complex work. agendum is an MCP server that gives any agent (Claude Code, Cursor, Windsurf, Cline, and others) persistent project state, bounded work packages, and cross-session continuity.

Quick Start

pip install agendum                                    # or: uvx agendum
claude mcp add agendum -- uvx agendum --home serve     # add to Claude Code
# Done. pm_* tools are now available in your agent.

Works with any MCP client — see setup for Cursor, Windsurf, VS Code, and others.

How It Works

flowchart LR
    A["PLAN\nwrite plan file"] --> B["pm_ingest\nboard items + deps"]
    B --> C["pm_next\nwork package + context"]
    C --> D["EXECUTE\nagent implements"]
    D --> E["pm_done\ndecisions + patterns"]
    E -->|next task| C
    E -->|new session| F["pm_status\nresume context"]
    F --> C

Each pm_done records decisions and patterns that enrich future pm_next calls — context compounds across sessions.

Example session:

You: I have a plan file for the API rewrite. Ingest it.

Agent:
  → pm_ingest(project="api-rewrite", plan_file="plan.md")

  Ingested 4 board items from plan:
    item-001: Schema design [high]
    item-002: Resolver layer (depends on item-001)
    item-003: Auth middleware (depends on item-001)
    item-004: Integration tests (depends on item-002, item-003)

You: What should I work on?

Agent:
  → pm_next(project="api-rewrite")

  Work package for item-001 "Schema design":
    Context: project rules, memory from last session
    Scope: Define GraphQL schema types
    Acceptance criteria: Types for User, Product, Order

You: Done with the schema. Here's what I decided...

Agent:
  → pm_done(project="api-rewrite", item_id="item-001",
      decisions="Using code-first with Strawberry",
      patterns="N+1 queries need DataLoader",
      verified=True)

  Marked item-001 as done. Unblocked: item-002, item-003
  > Next: pm_next("api-rewrite") to continue with newly unblocked tasks

Execution Loop

Knowledge & Search

Hybrid Search

pm_search combines three signals to find relevant knowledge across memory, learnings, and completed board items:

• FTS5 with Porter stemming — auth matches authentication, config matches configuration. Always on, zero config.
• Vector search (optional) — Install agendum[vectors] to add semantic similarity via fastembed + sqlite-vec. Activates automatically alongside FTS5.
• Entity graph — Topics and tags form a knowledge graph. Entries sharing 2+ entities are linked automatically. Graph expansion surfaces related knowledge that keyword search misses.

All three signals are fused via Reciprocal Rank Fusion (RRF), then reranked by recency and access frequency. The index rebuilds from Markdown files — no data loss if it gets corrupted.

Key Capabilities

• Adaptive context budget — enrichment scales with task complexity: 4K chars for trivial tasks, up to 10K for large ones
• Verification gate — pm_done(verified=True) distinguishes tested from untested completions
• Git auto-extract — pm_done reads git diff and git log automatically when no files are specified
• Pluggable enrichment pipeline — four context sources injected into every work package: project rules (CLAUDE.md/AGENTS.md), memory, dependency context, learnings
• Dependency resolution — topological ordering with cycle detection; dependents unblock automatically when upstream tasks complete
• Memory health — pm_status warns about corrupted entries; pm_consolidate strips XML fragments, deduplicates, and flags contradictions
• Zero config — auto-initializes on first tool call, derives board name from git remote
• Git-native storage — all state is human-readable Markdown + YAML in .agendum/, diffable and committable

Installation

All MCP clients except VS Code use the same config. Add to the appropriate file:

{
  "mcpServers": {
    "agendum": {
      "command": "uvx",
      "args": ["agendum", "--home", "serve"]
    }
  }
}

VS Code (GitHub Copilot): Uses "servers" instead of "mcpServers". Add to .vscode/mcp.json:

{
  "servers": {
    "agendum": {
      "command": "uvx",
      "args": ["agendum", "--home", "serve"]
    }
  }
}

CLI (standalone)

pip install agendum
agendum project create my-app   # Create a project
agendum status                  # Dashboard overview
agendum next my-app             # Suggest next task

Storage Layout

All state lives in ~/.agendum/ (or .agendum/ in your project if you prefer local storage):
