What is Ark-Space CLAUDE.md?

Repository instructions for ArkSpace, a project containing reusable agent skills, roles, registries, and plugin metadata. They define where different files belong and which checks to run after changes.

For directing Claude Code or Codex work in the ArkSpace repository, including choosing skills, editing manifests, validating structure, and running project checks.

They reduce uncertainty about project structure and the validation steps needed before releasing 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.

Model	Per session	Once invoked
Fable 5.1	$0.00130	$0.00130
Opus 5.5	$0.00052	$0.00052
Sonnet 5.5	$0.00026	$0.00026
Haiku 4.5	$0.00013	$0.00013

Security

Grade A, and why

Ark-Space CLAUDE.md 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 1mo 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.

What it actually says

Claude Code Guidance

Read AGENTS.md for the project contract and workflow. This file adds no separate architecture or Skill source tree for Claude Code.

Use canonical content from skills/ when Skills are introduced.
Treat arks as an external executable boundary, not an importable Skill runtime.
Ask before installing CLI tools, packages, or changing user-level configuration.
Do not create Claude-specific copies of Skill bodies.
Support Claude Code plugin installation through canonical plugin metadata that selects shared Skills.
Follow the plugin release boundary in docs/maintenance.md; manifests reference canonical Skills directly and no plugin mirror is generated.

Changes

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.
