020-planning-enhance-ai-plan-mode

020-planning-enhance-ai-plan-mode is a skill for Claude Code, Codex from jabrena/cursor-rules-examples. It costs 74 tokens per session (479 once invoked), scanned A, original, Apache-2.0.

A guide for creating structured implementation plans in Cursor’s planning mode for Java work. It includes outside-in test-driven development, or TDD, where tests are written from the user-facing behavior inward.

In plain words
What is it for?
It helps gather context, draft and validate a plan, map the approach with Mermaid diagrams, list files and tasks, and execute work while updating status.
Why use it?
It gives complex features, refactors, and API changes a consistent plan, with required sections and progress tracking for each task.

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

020-planning-enhance-ai-plan-mode 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 12d 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

Java Design Plan Creation for Cursor Plan Mode

Guide the process of creating a structured plan using Cursor Plan mode. This is an interactive SKILL. Plans follow a consistent section structure suitable for Java feature implementation, refactoring, or API design.

What is covered in this Skill?

  • Plan mode workflow: enter Plan mode, gather context, draft plan, iterate
  • YAML frontmatter: name, overview, todos, isProject
  • Required sections: Requirements Summary, Approach (with Mermaid), Task List, Execution Instructions, File Checklist, Notes
  • London Style (outside-in) TDD pattern
  • Plan execution discipline: update Status after each task before advancing
  • Plan file path: .cursor/plans/YYYY-MM-DD_<name>.plan.md

Constraints

Gather context before drafting. Include Execution Instructions in every plan. Never advance to next task without updating the plan's Status column.

  • MANDATORY: Run date before starting to get date prefix for plan filename
  • MUST: Read the reference template fresh—do not use cached content
  • MUST: Ask one or two questions at a time; never all at once
  • MUST: Validate summary ("Does this capture what you need?") before proposing plan creation
  • MUST: Wait for user to confirm "proceed" before generating the plan
  • MUST: Include Execution Instructions section in every generated plan

When to use this skill

  • Create a plan with Cursor Plan mode
  • Write a plan with Claude Plan mode

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.
