plan-plus

plan-plus is a skill for Claude Code, Codex from ww-w-ai/bkit-claude-code. It costs 66 tokens per session (1,690 once invoked), scanned A, original, Apache-2.0.

A planning workflow that combines brainstorming with structured development planning for a single feature. YAGNI means checking that unnecessary work is not included.

In plain words
What is it for?
Use it to discover intent, explore alternatives, review the feature scope, validate the design incrementally, and generate a planning document.
Why use it?
It helps clarify ambiguous requirements, compare implementation approaches, and remove needless features before design and coding begin.

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

plan-plus 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 yesterday.

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.

Plan Plus — Brainstorming-Enhanced PDCA Planning

Combines brainstorming's intent discovery with bkit PDCA's structured planning to produce higher-quality Plan documents through collaborative dialogue.

Overview

Plan Plus enhances the standard /pdca plan by adding 4 brainstorming phases before document generation. This ensures that user intent is fully understood, alternatives are explored, and unnecessary features are removed before any implementation begins.

When to use Plan Plus instead of /pdca plan:

  • The feature has ambiguous or complex requirements
  • Multiple implementation approaches are possible
  • You want to ensure YAGNI compliance from the start
  • The feature involves significant architectural decisions

Phase 1: Intent Discovery (1 question at a time)

Phase 2: Alternatives Exploration (2-3 approaches)

Phase 6: Next Steps → /pdca design {feature}

Phase Details

Phase 0: Project Context Exploration (Automatic)

Before asking any questions, explore the current project state:

  1. Read CLAUDE.md, package.json, pom.xml, etc. for project information
  2. Check recent 5 git commits (understand current work direction)
  3. Check existing docs/01-plan/ documents (prevent duplication)
  4. Check .bkit-memory.json (check ongoing PDCA status)

Share exploration results briefly: "I've reviewed the current project state: ..."

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.
