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

asc-cli-usage 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 6d 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

asc CLI Usage

Iron Law

NEVER GENERATE ASC COMMANDS WITHOUT RUNNING asc --help OR SUBCOMMAND --help FIRST

Always use --help to discover current flags and subcommands. The asc CLI evolves — never assume flags from memory.

Command discovery

  • Always use --help to discover commands and flags.
    • asc --help
    • asc builds --help
    • asc builds list --help

Flag conventions

  • Use explicit long flags (e.g., --app, --output).
  • No interactive prompts; destructive operations require --confirm.
  • Use --paginate when the user wants all pages.

Output formats

  • Default output is minified JSON.
  • Use --output table or --output markdown only for human-readable output.
  • --pretty is only valid with JSON output.

Authentication and defaults

  • Prefer keychain auth via asc auth login.
  • Fallback env vars: ASC_KEY_ID, ASC_ISSUER_ID, ASC_PRIVATE_KEY_PATH, ASC_PRIVATE_KEY, ASC_PRIVATE_KEY_B64.
  • ASC_APP_ID can provide a default app ID.

Timeouts

  • ASC_TIMEOUT / ASC_TIMEOUT_SECONDS control request timeouts.
  • ASC_UPLOAD_TIMEOUT / ASC_UPLOAD_TIMEOUT_SECONDS control upload timeouts.

Documentation Sources

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.
