ark-explain

ark-explain is a skill for Claude Code, Codex from pedroknigge/arkgate. It costs 17 tokens per session (3,739 once invoked), scanned A, original, MIT.

A plain-language guide to this project's architecture and its rules file, with an HTML report. It also explains which setup or automation command to use at each stage.

In plain words
What is it for?
Learning the folder structure, understanding a specific rule, investigating a blocked gate, and reviewing architecture gaps.
Why use it?
It helps you understand why a gate blocked a change and what remains incomplete, instead of treating a green check as proof that the architecture is finished.

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

ark-explain 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 27d 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.

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.

/ark-explain — Understand this project's architecture

Contener · Guiar · Ordenar. In plain words: contain the write, guide the next step, order leftover mess. This door is Guiar: teach the path in plain language. Skills never enforce — CLI / hooks / CI do.

Not a first-run door. Teach / HTML tour only. Session 0 → /ark-adopt. Map → /ark-explore. Apply → /ark-autopilot. Wire ArkRun → /ark-runtime. Wire ArkOrder → /ark-order.

The user wants to understand the architecture, a specific rule, or why the gate blocked them.

Improvement compass (process preflight)

When doctor is available, read doctor.improvementCompass (or the human Improvement compass section). Name 1–3 residual lenses in plain language before skill-shopping. Always notAScore — never invent 0–10 scores or Excellent/Good ranks.

What the user should feel next: fewer blocked AI writes, clearer folders, safer domain — then jargon.

Anti false-done: empty plan A + residual lenses / design-weak → Incomplete? yes. Green edges alone are not “architecture finished.” A doctor green / Healthy line must name a file, config key, or test; uncited green is unfinished.

AI-easy architecture: ports over concrete I/O in domain; one concern per module; golden pattern for new files; place before write (/ark-place / prepare-write).

Out of scope (honest): scalability/performance, full app-security tooling (SAST), and full resilience patterns are out-of-scope lenses — say so; do not invent Ark enforcement for them.

Tour by lenses (teach, not score). Prefer showcase HTML + doctor compass section when explaining residual.

When / not when

Use /ark-explain when… Do not use it when…
Plain-language tour of layers/rules/report Decision-grade recon / dual-plan → /ark-explore
“Why did the gate block me?” pedagogy Apply fixes → /ark-autopilot
Generate / walk HTML showcase report Fitness numbers only → /ark-coverage; brownfield action → /ark-adopt
Your job is to teach with this repo's real data and leave a shareable visual artifact.

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.
