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

no-private-leak 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 4d 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

This repo is public. Chat is not.

Files, comments, commits, PRs and docs are readable by anyone. Never copy the conversation into the tree.

Comments

Explain the code — why this branch exists, which invariant it protects, which silent failure it avoids.

Never write: what we discussed, "as you asked", "Victor said", pasted shell (cat > file <<), home paths, emails, billing/plan, or private brand / wiki names.

// BAD
cwd: "~/projeto-exemplo"

// GOOD — on-screen fake prompt, not a filesystem path
cwd: "remotion-agent-catalog"

Never commit

  • Absolute home paths (/Users/…, ~/…)
  • Personal emails. Git author: [email protected]
  • Metrics/logs: store repo-relative paths even if the tool wrote an absolute one
  • User-Agent: this repo's GitHub URL, not a mailbox
  • Private company or wiki names in comments, skills, or docs

If a script dumps an absolute path, rewrite it before commit. If a doc is a pasted terminal session, rewrite the doc.

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.
