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

new-features-planning 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

  • When being asked to make new features, make sure that you check out from main a new branch and make incremental commits
    • Use conventional commit format: <type>(<scope>): <description>
      • Types: feat, fix, docs, style, refactor, perf, test, chore
      • Example: feat(validation): add email validation function
      • Keep commits focused on a single change
      • Write descriptive commit messages in imperative mood
    • Use git commit -m "type(scope): subject" -m "body" -m "footer" for multiline commits
  • If the feature is very large, create a temporary todo.md
  • And start a pull request using gh
    • Create PRs with multiline bodies using:
      gh pr create --title "feat(component): add new feature" --body "$(cat <<EOF
      ## Description
      Detailed explanation of the changes
      
      ## Changes
      - List important changes
      - Another change

      EOF
      )" -r jxnl,ivanleomk
      
    • Or use the -F flag with a file: gh pr create -F pr_body.md
  • Make sure to include This PR was written by [Cursor](mdc:cursor.com)
  • Add default reviewers:
    • Use gh pr edit <id> --add-reviewer jxnl,ivanleomk
    • Or include -r jxnl,ivanleomk when creating the PR
  • use gh pr view <id> --comments | cat to view all the comments
  • For PR updates:
    • Do not directly commit to an existing PR branch
    • Instead, create a new PR that builds on top of the original PR's branch
    • This creates a "stacked PR" pattern where:
      1. The original PR (base) contains the initial changes
      2. The new PR (stack) contains only the review-related updates
      3. Once the base PR is merged, the stack can be rebased onto main

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.
