Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00022 | $0.00397 |
| Opus 5 | $0.00011 | $0.00198 |
| Sonnet 5 | $0.00004 | $0.00079 |
| Haiku 4.5 | $0.00002 | $0.00040 |
Grade A, and why
rc-validate scanned grade A with 0 findings 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 3d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Data Validation
Validate Reality Check database integrity and referential consistency. Run after adding data or before committing.
When This Skill Activates
- "Validate the database"
- "Check data integrity"
- "Run validation"
Validate Reality Check database integrity and referential consistency.
Usage
rc-validate
# or: uv run python scripts/validate.py
Options
--strict: Fail on warnings (not just errors)--json: Output results as JSON--fix: Attempt to auto-fix simple issues (use with caution)
Checks Performed
- Schema validation - All records match expected schema
- ID format - Claim IDs match
DOMAIN-YYYY-NNNformat - Referential integrity - All source_ids point to existing sources
- Embedding completeness - All records have vector embeddings
- Required fields - No missing required fields
- Duplicate detection - No duplicate IDs
Output
Validation Results:
- Claims: 42 checked, 0 errors, 1 warning
- Sources: 15 checked, 0 errors, 0 warnings
- Chains: 3 checked, 0 errors, 0 warnings
- Predictions: 8 checked, 0 errors, 0 warnings
Status: OK (1 warning)
When to Run
- After adding new claims/sources
- Before committing data changes
- As part of CI/CD pipeline
- When debugging data issues

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.

rc-validate is a skill published in the GitHub repository lhl/realitycheck (41 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 22 tokens to every session and 397 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
