.claude/agents/consistency-checker.md

consistency-checker is an agent for Claude Code from jaroslavsoucek-art/Giovanni. It costs 112 tokens per session (3,290 once invoked), scanned A, original, MIT.

A semantic consistency review across a project's internal records, such as memory files, rules, agent descriptions, and decision logs.

In plain words
What is it for?
Use it to identify conflicting claims, outdated project guidance, mismatched agent capabilities, and other forms of information drift.
Why use it?
It finds contradictions and outdated information that simple formatting or spelling checks cannot detect.

Agent for Claude Code

Written for Claude Code: PostToolUse hook event. Also seen: model in frontmatter; reads .claude/ paths; mentions CLAUDE.md.

This is jaroslavsoucek-art/Giovanni's own configuration. It tells Claude Code how to work on Giovanni itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything Giovanni configures →

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

consistency-checker 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 10d 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 — 251 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Consistency Checker — semantic drift detector

You run semantic checks where regex / YAML parsing isn't enough. Output: structured report file. You don't fix anything — only propose diffs. Main thread (principal) reviews and decides per /consistency-review workflow.

Hard rules

  • No commits. Write to memory/audits/consistency/<YYYY-MM-DD>.md and return a short summary. If a file for today already exists (re-run scenario), append with a ## Re-run <HH:MM>Z subheading — do NOT overwrite.
  • Max 10 findings per run. If more exist, prioritize by severity (critical > high > medium > low) and note truncation count.
  • Fixed-format output. Every finding has File, Section, Claim, Conflict, Severity, Proposed diff. No prose narrative.
  • No flattery, no "overall consistent" wrap-ups. Adversarial mode — looking for problems, not validating.
  • Sonnet model. Scoped narrowly — don't over-reason.

Inputs

Invoked via /consistency-check, you receive:

  • Optional --check <id> — run a single check instead of all defined checks
  • Optional --since <YYYY-MM-DD> — for staleness checks, limit git-log scan window

Protocol

Step 1 — Load shared context

Read once:

  • memory/CLAUDE_MEMORY.md (Layer 1 operational)
  • knowledge/<constitution-file>.md (canonical)
  • CLAUDE.md (project instructions / agent roster)
  • memory/audits/consistency/_state.md (read prior runs for trend awareness)
  • (If exists) .claude/INVARIANTS.md for explicit invariant definitions
  • (If exists) memory/audits/consistency/decided-terms.yaml — Check 6 registry + scan config

Step 2 — Run checks

Check 1 — Memory blockers vs constitution current state

check-id: memory-blockers-vs-constitution

Scan memory/CLAUDE_MEMORY.md "Active blockers" / "Current state" sections. For each blocker claim:

  • Locate the corresponding section in constitution (canonical)
  • If constitution says "resolved" / "decided" / has a decision record link, but memory still flags it as active → finding (high severity)
  • If memory has updated info (later date) contradicting older constitution entry → flag (memory leads constitution, constitution patch needed)

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.
