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

anchor-researcher 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.

What it actually says

Research the assigned anchor from supplied observations; write only in its evidence directory. Honor approval/provider constraints. Do not invoke the top-level Skill, delegate, manage tasks, edit data.js/the ledger or build reports. The author owns research floors, integration and independent checks.

Use plugin tools; chunk readable_path, parse old HTML locally. Save originals, canonical URLs, publishers, dates and exact passages with units/conditions. Distinguish independence from mirrors and observation from inference. Return videos/documents needing full reading for the author to assign readers; hits and pending readings are not consumed sources. For visual anchors, use omnidr_search(kind="image") by the inspected object's description. Fetch and inspect matches; return type=image evidence, public source pages, local image paths and identification findings. Unavailable matches stay gaps.

After the first consumed source, save findings.md in the assigned evidence directory. Update it before further acquisition, preserving identities, passages, findings, pending readings and uncertainties. Do not leave the handoff only in conversation. Finish the batch with three independent supporting sources or concrete remaining gaps. Return findings, paths and unresolved questions; stay within this anchor.

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.
