brainstorming-planner

brainstorming-planner is a skill for Claude Code, Codex from mlopscommunity/Coding-Agents-Conference-skills. It costs 39 tokens per session (1,577 once invoked), scanned A, original, Apache-2.0.

A requirements-planning process that asks follow-up questions before complex coding work begins and breaks the work into phases.

In plain words
What is it for?
Use it to clarify complex features, prepare work across multiple files or teams, and organize tasks with interdependent parts.
Why use it?
It exposes missing details, assumptions, boundaries, and dependencies before they cause backtracking during implementation.

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

brainstorming-planner 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.

Brainstorming Planner

Overview

The Brainstorming Planner skill dramatically improves plan mode by forcing rigorous clarification before execution. Rather than jumping straight into coding, this skill intercepts the planning phase and asks detailed follow-up questions to uncover ambiguities, identify assumptions, and structure the work effectively.

Core principle: Investment in upfront planning saves 10x the time in rework. Spending 20-30 minutes on clear requirements prevents 2-3 hours of implementation backtracking.

Dependency: Claude Code CLI with standard claude command.

When to Use

  • Starting a complex task or feature implementation
  • When requirements are stated but specifics are unclear
  • Before work involving multiple files or interdependent systems
  • Before cross-team handoffs or parallel work
  • When you sense ambiguity but can't quite articulate it

When NOT to Use

  • Trivial tasks (single-line fixes, obvious changes)
  • When requirements are already crystal clear and fully scoped
  • Emergency fixes where speed matters more than planning

Common Mistakes

Mistake Why it's wrong
Skipping ahead to coding You'll discover missing requirements mid-implementation and waste time pivoting. Start here.
Not getting explicit confirmation You've analyzed the problem, but are you and the user aligned? Confirm before coding.
Treating vague answers as "good enough" "I don't know" is valuable data—it's an assumption to validate before you build on it.
Not documenting assumptions Untested assumptions are the #1 source of rework. Write them down, mark them as "untested."
Forgetting about edge cases Edge cases are how implementations break. Identify them early.
Skipping risk identification Risks identified upfront change how you approach implementation. Risks discovered mid-project derail everything.

The Planning Process

Step 1: Clarify the Goal

Ask the user to describe their goal in their own words. Then reflect back what you heard:

  • What problem are they solving?
  • Who benefits from this?
  • How will success be measured?

brainstorming-planner is a skill published in the GitHub repository mlopscommunity/Coding-Agents-Conference-skills (37 stars, last pushed 5mo ago), licensed Apache-2.0. It adds 39 tokens to every session and 1,577 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
