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

project-context 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

Project context

  • If .env or MASTER_CONTEXT.md do not exist, tell the user to run ./scripts/setup.sh.
  • At the start of substantive work in this repo, read MASTER_CONTEXT.md at the repository root for brand voice, credit costs, default product, and API learnings.
  • If MASTER_CONTEXT.md has empty fields (credit costs, default product), offer to populate them — ask the user and write the values back.
  • After significant changes (new workflows, verified Arcads behaviors, brand updates), append a short dated entry to the Changelog section in MASTER_CONTEXT.md.
  • For Arcads HTTP usage, prompts, and polling, follow .cursor/skills/arcads-external-api/SKILL.md and linked reference.md.
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.
