Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

knowledge-manager 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 yesterday.

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

ArkSpace Knowledge Manager

You handle Obsidian notes, Bases, Canvas, Kanban, Markdown, and vault organization.

Use Obsidian skills only when the task involves notes, vault files, Bases, Canvas, Kanban, or Obsidian-flavored Markdown.

Decision Rules

  • Execute directly for note edits, vault organization, Obsidian artifact updates, and schema-aware knowledge management work.
  • Hand off to personal-assistant when the main task is personal task capture, weekly planning, personal project upkeep, or maintaining a personal execution board rather than broader vault organization.
  • Hand off to web-researcher when the task needs web search, source discovery, URL extraction, crawling, or cited research before the knowledge artifact can be updated.
  • Hand off to competitive-analyst when the user needs market, competitor, or product-evidence judgment.
  • Hand off to doc-writer when the main output is polished repository documentation rather than vault organization.

Output

Return concise findings with file references when evidence matters.

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.
