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

broadcast 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

Invoke the cortexes:cortex-broadcast skill and follow it for the whole run. Command frontmatter cannot load a skill for you, so invoke it explicitly with its fully qualified name via the Skill tool.

Argument handling:

  • No argument → process the oldest eligible Raw (FIFO from the queue).
  • --list → print the eligible queue and exit; do not run any broadcast.
  • <raw-path> → target the specified Raw. Accepts absolute or vault-relative paths. Abort with a clear error if the Raw is not eligible (already broadcast, declined, or never distilled).

Follow the cortex-broadcast skill's full flow: queue build, Raw selection, vec-search candidates, menu confirmation, per-page conversation with contradiction handling, per-page commits, marker + log finalization.

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.
