root-cause-validator

root-cause-validator is a skill for Claude Code from ihabkhaled/AI-Psychiatry. It costs 24 tokens per session (644 once invoked), scanned A, a copy of anti-gaming, MIT.

A debugging guide for finding the actual cause of failures in code changes, assertions, mocks, exceptions, or other symptoms.

In plain words
What is it for?
Use it to investigate failing tests, unexpected exceptions, incorrect mocks, or confusing behavior before making a focused fix.
Why use it?
It helps prevent treating symptoms or assumptions as proof. It keeps the investigation tied to observable evidence and records what was expected versus what happened.

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

root-cause-validator 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 9d 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.

Root Cause Validator

Core principle

Semantic compliance is stronger than literal compliance. Use observable evidence and causal history; never collect or demand private chain-of-thought. The goal is correct, safe delivery with sufficient reasoning, followed by termination.

Procedure

  1. Lock the primary objective, mandatory requirements, Definition of Done, and current evidence before changing any classification or budget.
  2. Identify the specific observable signal. Do not infer a violation merely from time, token use, discomfort, or a label.
  3. Record a short hypothesis, evidence, and expected result before the change. Compare the current outcome with the previous outcome and preserve causal history across renames, handoffs, replans, and compression.
  4. Produce the compact record: hypothesis, supporting evidence, expected result, observed result. Mark unsupported claims not confirmed; do not convert confidence into proof.
  5. Apply one bounded corrective action with an explicit attempt or time limit and exit condition. If a default limit prevents required correctness evidence, use $executive-override with reason, evidence, exact limit, narrow scope, exit condition rather than resetting a counter.
  6. Revalidate only the affected requirement or policy. Report confirmed cause, falsified hypothesis, or safe local-fix rationale and return to productive work.

Repository runtime

Apply this procedure inside the installed .ai/ framework. Record observable state in the relevant JSON ledger and route detailed judgment to the linked rules and guides.

Semantic boundaries

  • System, platform, user, repository, domain, safety, security, permission, and destructive-action controls remain higher priority.
  • Equivalent actions share history when their hypothesis, expected evidence, target failure, and intended outcome are unchanged.
  • Preserve immutable parent, caused-by, and delegated-from identifiers across handoffs and context compression; missing ancestry makes depth not confirmed, never zero.
  • Activity alone is not progress. Completion and blockers require their structured evidence contracts.
  • Critical correctness evidence cannot be discarded because a retry, critic, verification, context, or delegation budget expired.
  • Security-negative cases are selected from explicit requirements and the observed trust boundary (identity, permission, ownership/tenant, denial response, and side effects). An agent may mark a case inapplicable only with evidence, not by shrinking Definition of Done.
  • An override permits one extension only. Do not renew or stack overrides unless materially new evidence justifies a separately recorded override; repeated renewal without convergence must stop and report the unresolved condition.

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.
