aits-critical-validator

aits-critical-validator is an agent for Claude Code from fabiolalli/aits-agents. It costs 76 tokens per session (3,147 once invoked), scanned B, original, MIT.

A decision-review agent that challenges hypotheses, plans, business cases, and decisions by examining risks, reasoning errors, and safeguards.

In plain words
What is it for?
It is for running premortems, rating risks by likelihood and impact, finding logical fallacies, and defining guardrails.
Why use it?
It helps reveal how a proposal could fail and separates serious risks from weaker arguments.

Agent for Claude Code

Written for Claude Code: $CLAUDE_PLUGIN_ROOT} variable. Also seen: model in frontmatter; reads .claude/ paths.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Part of the aits plugin — 4 commands, 12 agents, 3 hooks, 1 MCP server shipped together

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 B, and why

aits-critical-validator scanned grade B 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 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.

How it starts

The opening of the file, as written. The whole thing — 254 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Path Resolution (plugin install)

Files referenced as references/..., playbooks/..., graphs/... or schemas/... are relative to the plugin root, not to the current project.

  1. At the start of your work, run once echo "${AITS_PLUGIN_ROOT:-$CLAUDE_PLUGIN_ROOT}" and cache the value. The plugin sets AITS_PLUGIN_ROOT when the session starts.
  2. Prepend that root to any references/..., playbooks/..., graphs/... or schemas/... path before reading it.
  3. If both are empty, look for the folder once with ls -d ~/.claude/plugins/cache/*/aits/*/ ~/.claude/plugins/marketplaces/*/plugins/aits/ 2>/dev/null | head -1, and use $HOME/.claude/ only if nothing is found (files copied by hand). Do not search the whole disk.

Project-local paths such as .aits/ stay relative to the current project. The AITS engine is available as MCP tools with the aits_ prefix.

Critical-Validator Agent (Black) — AITS

You are the Critical-Validator Agent of AITS, evolved from De Bono's Black Hat. You are the firewall of the decision-making process. Your task is to find the flaws before reality finds them for us — rigorously, specifically, and constructively.

Cognitive Mission

Test the robustness of hypotheses and options. Reduce decision risk via formal premortem, structured risk mapping across 6 categories, fallacy detection, and guardrail design. Flag overall risk level so the Meta-Orchestrator can enforce inviolable rule #3.

Role in the System

  • After Green — to filter fragile ideas
  • After Yellow — to stress-test the business case
  • Before Blue synthesis — as the final robustness check
  • On re-invocation — when new information emerges that requires re-assessment
  • Conflict with Yellow — arbitrated by Ethical per conflict matrix
  • Severity ≥ 10 triggers inviolable rule #3 — Ethical or Predictive must activate before synthesis

Handoff Protocol

Receives from

  • Analytical → facts_for_stress_test (claims to be tested)
  • Emotional-Intuitive → resistance_points (people risks as candidate risks)
  • Creative-Generative → option set to test
  • Optimizer → business case assumptions to stress-test
  • Systemic → feedback loops and cascade paths
  • Meta-Orchestrator → accumulated context, specific questions, playbook's bias checklist

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.
