ark-place

ark-place is a skill for Claude Code, Codex from pedroknigge/arkgate. It costs 22 tokens per session (4,931 once invoked), scanned A, original, MIT.

A test marker showing that an agent has access to process-guidance skills during an ACS07 placement test.

In plain words
What is it for?
Testing agent placement and confirming that enforcement still happens through ark-check, hooks, or continuous integration.
Why use it?
It helps test whether skills are available without confusing them with the checks that enforce the result.

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-place 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 — 284 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/ark-place — Where does this code go?

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

When: you are adding a new file or artifact and need the layer, folder, and name. Not when: session 0 / config is missing or lying (/ark-adopt) or an existing violation cluster (/ark-autopilot).

Steps

  1. CLI-first: if the local CLI already resolved the root, skip waiting on MCP. Identity is optional then.
  2. Place with filePath required (ark_place or read ark.config.json + .ark/golden-pattern.json). Fail-closed without a path — never invent components/*.tsx or default to Presentation.
  3. Write it there. Then arkgate-check.

Checklist

  • filePath is known before the call. Description alone is not a path.
  • Golden pattern is load-bearing when present. Adopt generates it.
  • An included file that matches no layer is not a pass. The write gate denies it (CONFIG_UNCLASSIFIED_FILES). Place it in a layer folder, or send include/layer drift to /ark-adopt. Do not write into a loose include gap.
  • Do not default a repository to Presentation.
  • When the matched layer has layers[].description, print that caption next to the layer name and globs. Omit when absent — do not invent a caption or /ark-describe.
  • When arkRun is on: scaffold through the kernel (no new of managed types; declare uses / reactsTo / raises / sends; factory only in arkRun.kernelRoots, compositionRoots alias). Extra off → do not introduce the kernel. Enable it via /ark-adopt. Skills never enforce.
  • When arkOrder is on: factory only in arkOrder.planeRoots; Domain stays plane-free; first freeze ξ with release(); later ξ is proposeRelease then apply. Extra off → do not introduce the plane. Enable it via /ark-adopt. Skills never enforce.

Autonomy contract

Invoking this skill is the approval. If the user described an artifact, write the files in this turn (prepare-write + scaffold). A path table alone is incomplete. The CLI is a sensor and gate. CLI budget: ark_identity then ark_place when using MCP (or skip identity if the CLI already resolved the root); otherwise read ark.config.json; write; ark-check. Do not ask which layer they prefer.

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-place is a skill published in the GitHub repository pedroknigge/arkgate (1 stars, last pushed today), licensed MIT. It adds 22 tokens to every session and 4,931 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.
