.claude/commands/crossframe-history.md

crossframe-history is a command for Claude Code from xi-kari/crossframe-skill. It costs 0 tokens per session (101 once invoked), scanned A, original, MIT.

A command for researching and organizing historical records, institutions, dynasties, archives, and freedom-of-information requests. It sets limits on what the available evidence can prove.

In plain words
What is it for?
Use it to study historical sources, track missing archive material or FOIA requests, examine institutional continuity, and define local historical boundaries.
Why use it?
It helps prevent treating archive listings, official agreements, or unfinished records as confirmed historical facts.

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

crossframe-history 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 8d 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

/crossframe-history

Use CrossFrame History for historical materials, civilization continuity, source-ledger boundaries, dynasty or institutional history, archive-access backlog, FOIA closeout, or local C5 boundary summaries.

This explicit command is allowed. Read skills/crossframe-history/SKILL.md, then follow its routed instructions. Do not treat archive paths, finding aids, FOIA backlog, official agreements, or limited strong closure as full factual closure.

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.
