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

rspack-v2-upgrade 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 8d 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

Rspack 1.x to v2 Upgrade

Workflow

  1. Confirm current setup

    • Read package.json to identify Rspack packages in use.
    • Locate the Rspack config file (commonly rspack.config.(ts|js|mjs|cjs)).
  2. Open the official migration guide

  3. Plan required changes

    • Compare the current project config with the migration guide.
    • List breaking changes that apply to the project’s current config and plugins.
    • Note any removed or renamed options, defaults, or plugin APIs.
  4. Update dependencies

    • Upgrade Rspack packages to v2: @rspack/core, @rspack/cli, @rspack/dev-server, @rspack/plugin-react-refresh.
  5. Apply migration changes

    • Update the Rspack config and related code according to the official guide.
    • Remove deprecated or unsupported options.
  6. Validate

    • Run build and dev commands.
    • Run project tests or type checks.
    • Fix any warnings or errors surfaced by the new version.

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.
