In plain words
What is it for?

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

rc-analyze scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Manual 3-Stage Analysis

Perform a full 3-stage analysis following the Reality Check methodology. Use for manual analysis without automatic database registration.

When This Skill Activates

  • "Analyze this source"
  • "Do a 3-stage analysis"
  • "Manual analysis of"

Perform a full 3-stage analysis following the Reality Check methodology. Use this for manual analysis when you want to review claims before registering them.

Prerequisites

Environment

Set REALITYCHECK_DATA to point to your data repository:

export REALITYCHECK_DATA=/path/to/realitycheck-data/data/realitycheck.lance

The PROJECT_ROOT is derived from this path - all analysis files go there.

CLI Commands

Reality Check provides CLI tools (rc-db, rc-validate, rc-export, rc-embed).

Check availability:

which rc-db  # Should show path if pip-installed

If commands are not found, either:

  1. Install: pip install realitycheck (recommended)
  2. Use uv run from framework directory: uv run python scripts/db.py ...
  3. Add framework as submodule and use: .framework/scripts/db.py ...

Red Flags: Wrong Repository

IMPORTANT: Always write to the DATA repository, never to the framework repository.

If you see these directories, you're in the framework repo (wrong place for data):

  • scripts/
  • tests/
  • integrations/
  • methodology/

Stop and verify REALITYCHECK_DATA is set correctly.

Data Source of Truth

LanceDB is the source of truth, not YAML files.

  • Query sources: rc-db source get <id> or rc-db source list
  • Query claims: rc-db claim get <id> or rc-db claim list
  • Search: rc-db search "query"

Ignore YAML files like claims/registry.yaml or reference/sources.yaml - these are exports/legacy format.

Fetching Content

To retrieve and parse source content:

  • Primary: WebFetch for most URLs
  • Alternative: curl -L -sS "URL" | rc-html-extract - --format json
  • rc-html-extract returns structured {title, published, text, headings, word_count}

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
