realitycheck 0.3.1

Framework for rigorous, systematic analysis of claims, sources, predictions, and argument chains

Reality Check

A framework for rigorous, systematic analysis of claims, sources, predictions, and argument chains.

With so many hot takes, plausible theories, misinformation, and AI-generated content, sometimes, you need a realitycheck.

Overview

Reality Check helps you build and maintain a unified knowledge base with:

• Claim Registry: Track claims with evidence levels, credence scores, and relationships
• Source Analysis: Structured 3-stage methodology (descriptive → evaluative → dialectical)
• Evidence Links: Connect claims to sources with location, quotes, and strength ratings
• Reasoning Trails: Document credence assignments with full epistemic provenance
• Prediction Tracking: Monitor forecasts with falsification criteria and status updates
• Argument Chains: Map logical dependencies and identify weak links
• Semantic Search: Find related claims across your entire knowledge base

See realitycheck-data for a public example knowledge base built with Reality Check.

Status

v0.3.1 - Analysis Rigor & Inbox Workflow: Layer/Actor/Scope/Quantifier columns, --rigor flag, filing workflow; 412 tests.

Prerequisites

• Python 3.11+
• Claude Code (optional) - For plugin integration
• OpenAI Codex (optional) - For skills integration
• Amp (optional) - For skills integration
• OpenCode (optional) - For skills integration

Installation

From PyPI (Recommended)

# Install with pip
pip install realitycheck

# Or with uv (faster)
uv pip install realitycheck  # installs to active venv or system Python

# Verify installation
rc-db --help

From Source (Development)

# Clone the framework
git clone https://github.com/lhl/realitycheck.git
cd realitycheck

# Install dependencies with uv
uv sync

# Verify installation
REALITYCHECK_EMBED_SKIP=1 uv run pytest -v

GPU Support (Optional)

The default install uses CPU-only PyTorch. For GPU-accelerated embeddings:

# NVIDIA CUDA 12.8
uv sync --extra-index-url https://download.pytorch.org/whl/cu128

# AMD ROCm 6.4
uv sync --extra-index-url https://download.pytorch.org/whl/rocm6.4

AMD TheRock nightly (e.g., gfx1151 / Strix Halo):

TheRock nightlies provide support for newer AMD GPUs not yet in stable ROCm. Replace gfx1151 with your GPU arch.

Note: TheRock support is experimental. Newer architectures (gfx1151/RDNA 3.5, gfx1200/RDNA 4) may require matching system ROCm kernel drivers. Memory allocation may work but kernel execution can fail if there's a version mismatch between pip ROCm userspace and system kernel module.

# 1. Install matching ROCm SDK (system-wide)
pip install --index-url https://rocm.nightlies.amd.com/v2/gfx1151/ "rocm[libraries]" -U

# 2. Create fresh venv with ROCm torch
rm -rf .venv && uv venv --python 3.12
VIRTUAL_ENV=$(pwd)/.venv uv pip install --index-url https://rocm.nightlies.amd.com/v2/gfx1151/ torch
VIRTUAL_ENV=$(pwd)/.venv uv pip install sentence-transformers lancedb pyarrow pyyaml tabulate

# 3. Set library path and verify
export LD_LIBRARY_PATH="$(pip show rocm-sdk-core | grep Location | cut -d' ' -f2)/_rocm_sdk_devel/lib:$LD_LIBRARY_PATH"
.venv/bin/python -c "import torch; print(torch.version.hip); print(torch.cuda.is_available())"

Or set UV_EXTRA_INDEX_URL in your shell profile for persistent configuration.

Note: If switching GPU backends, force reinstall torch:

rm -rf .venv && uv sync --extra-index-url <your-index-url>

Quick Start

1. Create Your Knowledge Base

# Create a new directory for your data
mkdir my-research && cd my-research

# Initialize a Reality Check project (creates structure + database)
rc-db init-project

# This creates:
#   .realitycheck.yaml    - Project config
#   data/realitycheck.lance/  - Database
#   analysis/sources/     - For analysis documents
#   tracking/             - For prediction tracking
#   inbox/                - For sources to process (staging)
#   reference/primary/    - Filed primary documents
#   reference/captured/   - Supporting materials

2. Set Environment Variable

# Tell Reality Check where your database is
export REALITYCHECK_DATA="data/realitycheck.lance"

# Add to your shell profile for persistence:
echo 'export REALITYCHECK_DATA="data/realitycheck.lance"' >> ~/.bashrc

3. Add Your First Claim

rc-db claim add \
  --text "AI training costs double annually" \
  --type "[F]" \
  --domain "TECH" \
  --evidence-level "E2" \
  --credence 0.8

# Output: Created claim: TECH-2026-001

4. Add a Source

rc-db source add \
  --id "epoch-2024-training" \
  --title "Training Compute Trends" \
  --type "REPORT" \
  --author "Epoch AI" \
  --year 2024 \
  --url "https://epochai.org/blog/training-compute-trends"

5. Search and Explore

# Semantic search
rc-db search "AI costs"

# List all claims
rc-db claim list --format text

# Check database stats
rc-db stats

Using with Framework as Submodule

For easier access to scripts, add the framework as a git submodule:

cd my-research
git submodule add https://github.com/lhl/realitycheck.git .framework

# Now use shorter paths:
.framework/scripts/db.py claim list --format text
.framework/scripts/db.py search "AI"

CLI Reference

All commands should be run with REALITYCHECK_DATA set.

If REALITYCHECK_DATA is not set, commands will only run when a default database exists at ./data/realitycheck.lance/ (and will otherwise exit with a helpful error suggesting how to set REALITYCHECK_DATA or create a project via rc-db init-project). The Claude Code plugin can also auto-resolve project config via .realitycheck.yaml.

# Database management
rc-db init                              # Initialize database tables
rc-db init-project [--path DIR]         # Create new project structure
rc-db stats                             # Show statistics
rc-db reset                             # Reset database (destructive!)

# Claim operations

Claude Code Plugin

Claude Code is Anthropic's AI coding assistant. Reality Check includes a plugin that adds slash commands for analysis workflows.

Install the Plugin

# From the realitycheck repo directory:
make install-plugin-claude

Note: Local plugin discovery from ~/.claude/plugins/local/ is currently broken. Use the --plugin-dir flag:

# Start Claude Code with the plugin loaded:
claude --plugin-dir /path/to/realitycheck/integrations/claude/plugin

# Or create a shell alias:
alias claude-rc='claude --plugin-dir /path/to/realitycheck/integrations/claude/plugin'

Plugin Commands

Commands are prefixed with /reality::

Command	Description
/reality:check <url>	Flagship - Full analysis workflow (fetch → analyze → register → validate)
/reality:synthesize <topic>	Cross-source synthesis across multiple analyses
/reality:analyze <source>	Manual 3-stage analysis without auto-registration
/reality:extract <source>	Quick claim extraction
/reality:search <query>	Semantic search across claims
/reality:validate	Check database integrity
/reality:export <format> <type>	Export to YAML/Markdown
/reality:stats	Show database statistics

Alternative: Global Skills

If you prefer skills over plugins:

make install-skills-claude

This installs skills to ~/.claude/skills/ which are auto-activated based on context.

Example Session

> /reality:check https://arxiv.org/abs/2401.00001

Claude will:
1. Fetch the paper content
2. Run 3-stage analysis (descriptive → evaluative → dialectical)
3. Extract and classify claims
4. Register source and claims in your database
5. Validate data integrity
6. Report summary with claim IDs

See docs/PLUGIN.md for full documentation.

Codex Skills

Codex doesn’t support Claude-style plugins, but it does support “skills”.

Codex CLI reserves /... for built-in commands, so custom slash commands are not supported. Reality Check ships Codex skills you can invoke with $...:

• $check ...
• $realitycheck ... (including $realitycheck data <path> to target a DB for the current Codex session)

Embeddings are generated by default when registering sources/claims. Only set REALITYCHECK_EMBED_SKIP=1 (or use --no-embedding) when you explicitly want to defer embeddings.

Install:

make install-skills-codex

See integrations/codex/README.md for usage and examples.

Amp Skills

Amp is Sourcegraph's AI coding assistant. Reality Check includes skills that activate on natural language triggers.

Install Skills

make install-skills-amp

Usage

Skills activate automatically based on natural language:

"Analyze this article for claims: https://example.com/article"
"Search for claims about AI automation"
"Validate the database"
"Show database stats"

See integrations/amp/README.md for full documentation.

OpenCode Skills

OpenCode is an open-source AI coding agent with 80K+ GitHub stars. Reality Check includes skills that integrate with OpenCode's skill system.

Install Skills

make install-skills-opencode

Usage

Skills are loaded on-demand via OpenCode's skill tool:

Load the realitycheck skill

Or reference skills in prompts:

Using the realitycheck-check skill, analyze https://example.com/article

Why a Unified Knowledge Base?

Reality Check recommends one knowledge base per user, not per topic:

• Claims build on each other across domains (AI claims inform economics claims)
• Shared evidence hierarchy enables consistent evaluation
• Cross-domain synthesis becomes possible
• Semantic search works across your entire knowledge base

Create separate databases only for: organizational boundaries, privacy requirements, or team collaboration.

Example Knowledge Base

See realitycheck-data for a public example knowledge base built with Reality Check, tracking claims across technology, economics, labor, and governance domains.

Embedding Model

Reality Check uses all-MiniLM-L6-v2 for semantic search embeddings. This model provides the best balance of performance and quality for CPU inference:

Model	Dim	Load Time	Throughput	Memory
all-MiniLM-L6-v2	384	2.9s	7.8 q/s	1.2 GB
all-mpnet-base-v2	768	3.0s	3.3 q/s	1.4 GB
granite-embedding-278m	768	6.0s	3.4 q/s	2.5 GB
stella_en_400M_v5	1024	4.4s	1.7 q/s	2.7 GB

The 384-dimension vectors are stored in LanceDB and used for similarity search across claims.

Note: Embeddings default to CPU to avoid GPU driver crashes. To use GPU:

export REALITYCHECK_EMBED_DEVICE="cuda"  # or "mps" for Apple Silicon

Development

# Run tests (skip slow embedding tests)
REALITYCHECK_EMBED_SKIP=1 uv run pytest -v

# Run all tests including embeddings
uv run pytest -v

# Run with coverage
uv run pytest --cov=scripts --cov-report=term-missing
