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

typescript-review 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 9d 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

TypeScript Review

Use this skill when a TypeScript change needs structured review rather than a generic pass.

Focus areas

  • type safety versus runtime reality
  • API and schema drift
  • async error paths
  • build and lint impact
  • test coverage for behavior changes
  • fast: review changed code paths and obvious type/runtime mismatches
  • standard: review impacted call sites, validation, and tests
  • strict: review edge cases, migrations, contracts, and likely regression surfaces

Review prompts

Ask:

  • can the runtime value violate the static type assumption?
  • are errors surfaced, swallowed, or rethrown consistently?
  • did a public contract change without matching validation or tests?
  • does the change rely on unsafe casts, optional values, or implicit coercion?

Output shape

Prefer:

  • findings first
  • open questions second
  • change summary last

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.
