README

Grainulator

Research that compiles.

Ask a question. Get a multi-pass investigation with typed claims, tension detection, and a confidence-graded answer. Not a chatbot — a research sprint that runs in under 60 seconds.

What it does

Multi-pass investigation — 3 research passes build evidence from different angles before synthesizing an answer
Typed claims, not vibes — every finding is tagged as factual, constraint, risk, recommendation, or estimate with an evidence tier (stated / web / documented / tested / production)
Tension detection — the compiler finds contradictions between claims and surfaces them before generating output
Confidence scoring — a 7-pass compiler grades evidence strength, type coverage, and bias to produce a 0-100 confidence score

Try the demo

grainulator.app runs a sprint in your browser. Type a question, watch three research passes execute, and see the compiled answer with claim breakdown.

What to expect from a single sprint:

Metric	Typical value
Claims generated	12-16
Claim types	5 (factual, constraint, risk, recommendation, estimate)
Tensions detected	3-6
Evidence tiers	web, documented, stated
Confidence score	63-68 / 100
Time to answer	40-70 seconds

The demo runs client-side to show the pipeline. The real tool (installed as a plugin) uses Claude for substantially higher quality research and deeper evidence.

Install

Step 1 — Add the marketplace (one-time):

claude plugin marketplace add https://github.com/grainulation/grainulator.git

Step 2 — Install:

claude plugin install grainulator

Inside Claude Code, use /plugin instead of claude plugin.

That's it. The plugin registers MCP servers, skills, hooks, and an autonomous agent.

Requirements: Claude Code with Node.js >= 20.

Alternative: clone directly

git clone https://github.com/grainulation/grainulator.git ~/.claude/plugins/grainulator

claude plugin add ~/.claude/plugins/grainulator

Team deployment

Commit to your project's .claude/settings.json:

{
  "enabledPlugins": ["grainulator@grainulation-marketplace"]
}

For air-gapped environments, use CLAUDE_CODE_PLUGIN_SEED_DIR with the plugin baked into container images.

Troubleshooting

MCP server disconnected / "tool not found". Claude Code's MCP registry occasionally drops stdio-connected servers (sleep, network hiccup, long-running session). Re-add the affected server:

claude mcp add wheat  -- npx -y -p @grainulation/wheat  wheat-mcp
claude mcp add mill   -- npx -y    @grainulation/mill   serve-mcp
claude mcp add silo   -- npx -y    @grainulation/silo   serve-mcp

Or run /healthcheck from any grainulator-enabled session to verify all three
