ingenious: Command for Claude Code

.claude/commands/viz/c4-verify.md

c4-verify is a command for Claude Code from Insight-Services-APAC/ingenious. It costs 0 tokens per session (2,758 once invoked), scanned C, original, MIT.

A command for checking a hierarchical C4 architecture map against the codebase. C4 is a method for showing a system at levels such as context, containers, components, and code.

In plain words
What is it for?
It checks completeness, accuracy, hierarchy, diagrams, and links between images and the existing architecture model.
Why use it?
It helps find missing or inaccurate architecture information before the map becomes misleading.

Command for Claude Code

Written for Claude Code: installed under .claude/. Also seen: mentions subagents.

This is Insight-Services-APAC/ingenious's own configuration. It tells Claude Code how to work on ingenious 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 ingenious 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 C, and why

c4-verify scanned grade C 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 yesterday.

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.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

C4 Architecture Verification

Validate accuracy and completeness of the hierarchical C4 architecture map.

Prerequisites

Existing model in codemap/<system-id>/. If not present, run /viz/c4-map first.

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.

c4-verify is a command published in the GitHub repository Insight-Services-APAC/ingenious (24 stars, last pushed 7mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,758 tokens. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-04.
