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

data-storage-reference 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 2mo 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

Rossum Data Storage API Reference

This skill provides the complete REST API reference for Rossum's Data Storage service — a MongoDB-compatible data layer used by the Master Data Hub and available for direct API access. For complete details, see reference.md.

Use this knowledge when:

  • Querying Data Storage collections via the REST API (find, aggregate)
  • Performing CRUD operations on documents (insert, update, delete, replace)
  • Running bulk write operations
  • Managing collections (create, rename, drop)
  • Managing indexes (create, drop, list) and Atlas Search indexes
  • Understanding async operation patterns (202 responses, operation status polling)
  • Debugging Data Storage API calls or understanding response schemas
  • Building integrations that read/write data to Rossum's Data Storage

Note: The rossum-api MCP server provides convenient tool wrappers for some of these endpoints (aggregate, list collections, list indexes). Use the MCP tools for interactive exploration; use this reference when building configurations or understanding the full API surface.

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.
