ark-coverage

ark-coverage is a skill for Claude Code, Codex from pedroknigge/arkgate. It costs 23 tokens per session (3,423 once invoked), scanned A, original, MIT.

A codebase audit for checking how widely ArkGate rules cover a project and whether its checks, baseline, and write path are in place.

In plain words
What is it for?
Use it to inspect ArkGate adoption, measure rule coverage, check enforcement gates and baseline settings, and produce a ranked list of remaining work.
Why use it?
It shows where architecture rules are missing or only appear to pass, so you can see what still blocks safe automated code changes.

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-coverage 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 today.

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 — 201 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/ark-coverage — Ark adoption fitness (not full recon)

Not a first-run door. Fitness numbers only (governed files, gates, baseline). Session 0 → /ark-adopt. Leftover design → /ark-explore. Apply → /ark-autopilot. Do not send the user to leftover /ark-contract or /ark-fix.

You audit how this repo uses ArkGate (coverage, gates, baseline, host write path) and what adoption gaps remain. Work autonomously. End with a ranked fitness report.

This is not /ark-explore. You do not produce a multi-pattern dual-plan or spaghetti Shape ladder by default. If the tree is design-weak under ENFORCE, handoff to explore.

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.”

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.

Fitness numbers + handoff when residual lenses are non-empty — never call coverage “done architecture.”

When / not when

Use /ark-coverage when… Do not use it when…
“How adopted is Ark?” governed%, gates, baseline, skills stale Full product map / what-next architecture → /ark-explore
Capability gaps (CI, write path, ESLint, optional layers) Apply fixes end-to-end → /ark-autopilot
Ranked adoption opportunities (install, ratchet, contract classify) Spaghetti pattern plan / golden pattern → /ark-explore dual-plan seed
Quick honesty before a release checklist One design trade-off → /ark-think

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.

ark-coverage is a skill published in the GitHub repository pedroknigge/arkgate (1 stars, last pushed yesterday), licensed MIT. It adds 23 tokens to every session and 3,423 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
