ark-loop

A shortcut for an Ark workflow that fixes illegal imports in a codebase. Ark is a set of tools and rules for checking software structure.

In plain words
What is it for?
It is for validating import-related changes, applying mechanically safe fixes, and checking that the result meets the project's rules.
Why use it?
It helps apply safe import fixes while requiring additional investigation when the problem needs design judgment.

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-loop 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 2d 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 — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/ark-loop — Shortcut to /ark-autopilot

Not a first-run door. This leftover name is a shortcut. Driving --plan to goal.met is /ark-autopilot. Do that job now. Auto-apply only the four mechanical-safe kinds; judgment you write.

Autonomy contract

Invoking this leftover name is the approval to apply plan A. Open every step file. Write. Re-check. Empty plan A + leftover design → /ark-explore then /ark-autopilot for one extraction card (never mechanical-safe B).

When / not when

Use this leftover name when… Prefer instead
Plan A has steps; drive to goal.met /ark-autopilot
Mechanical-safe + judgment apply Map only → /ark-explore; session 0 → /ark-adopt

Dual engine (mandatory)

Engine Role
Deterministic Only the four mechanical-safe kinds auto-apply; plan tags; gate re-check
Exploratory Read sources; detect concentrated edges / false-green before grinding

The CLI is a sensor, never the whole job. Claiming done without the exploratory bar for this skill is incomplete.

MCP workspace binding (mandatory)

Before any ark_* MCP tool, call ark_identity with project.expectedRoot set to the exact workspace root. Continue only when binding.status === "matched" and authoritative === true; retain projectIdentity.projectId, then pass both expectedRoot and expectedProjectId under project on every later MCP call. If identity is missing, mismatched, unverified, or the root is uncertain, do not consume MCP analysis: use the workspace-local CLI and report that MCP restart/retargeting is required. ark://manifest never satisfies this preflight.

Atomic multi-file work uses ark_prepare_change with the same matched project envelope.

Dual plane — layers + extras (mandatory, except /ark-runtime)

Label findings [Layer] vs [ArkRules] vs [ArkRun] vs [ArkOrder]. Absence of extras is valid and silent. Extra skip clusters (ARKRUN_* / ARKORDER_*) are /ark-autopilot. Never invent mechanical-safe kinds. Do not invent /ark-run or /ark-order. Skills never enforce.

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.

ark-loop is a skill published in the GitHub repository pedroknigge/arkgate (1 stars, last pushed 2d ago), licensed MIT. It adds 22 tokens to every session and 1,099 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.
