cross-validate-artifacts

cross-validate-artifacts is a skill for Claude Code, Codex from shep-ai/shep. It costs 109 tokens per session (1,768 once invoked), scanned A, original, MIT.

A documentation audit that compares files across a codebase to find inconsistent statements, conflicts, and contradictions.

In plain words
What is it for?
Use it to inspect project documentation, validate a specific category, report problems, or validate and automatically fix issues.
Why use it?
It helps reveal when documents describe different domain models, technologies, architecture, or commands.

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

cross-validate-artifacts 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 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.

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.

The opening of the file, as written. The whole thing — 228 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Cross-Validate Artifacts Skill

Cross-validate documentation and artifacts across the codebase for consistency, conflicts, and contradictions.

Trigger

Use this skill when the user:

  • Asks to "cross-validate", "validate docs", "check documentation consistency"
  • Wants to find conflicts or contradictions in documentation
  • Asks to audit or review documentation for accuracy
  • Uses /cross-validate-artifacts command

Arguments

  • No arguments: Perform validation and present results summary table, then ask user if they want to fix
  • validate and fix or fix: Perform validation AND automatically fix all issues found
  • --category <name>: Validate specific category only (domain-models, agent-system, tech-stack, architecture, cli-commands)

Validation Process

Step 1: Identify Documentation Sources

Gather all documentation files to validate:

Root docs:
- README.md
- CLAUDE.md
- AGENTS.md
- CONTRIBUTING.md

docs/ folder:
- docs/architecture/*.md
- docs/concepts/*.md
- docs/guides/*.md
- docs/development/*.md
- docs/api/*.md

Step 2: Break Into Validation Categories

Split validation into parallel sub-tasks for efficiency. Each category should be handled by a dedicated subagent:

Category Description Key Files to Compare
domain-models Entity definitions, fields, enums CLAUDE.md, docs/api/domain-models.md, docs/concepts/*.md
agent-system Agent names, tools, state schema, workflow AGENTS.md, docs/architecture/agent-system.md, docs/guides/langgraph-agents.md
tech-stack Framework versions, library references README.md, CLAUDE.md, docs/architecture/overview.md
architecture Layer descriptions, folder structure, patterns CLAUDE.md, docs/architecture/*.md, CONTRIBUTING.md
cli-commands pnpm scripts, paths, configuration CLAUDE.md, docs/development/.md, docs/guides/.md

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.
