ultraplan

ultraplan is a skill for Claude Code from irfad7/claude-power-skills. It costs 101 tokens per session (1,846 once invoked), scanned A, original, MIT.

A structured way to explore a complex software idea before turning it into an implementation plan. It examines the existing codebase, asks clarifying questions, challenges assumptions, and validates the direction.

In plain words
What is it for?
Use it when designing a feature, system, or project that needs architectural thinking, brainstorming, and a checked execution plan before coding.
Why use it?
It reduces the risk of building the wrong thing from an incomplete idea. The exploration helps connect the final task list to the actual problem.

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

ultraplan 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 11d 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.

UltraPlan — Creative Exploration → Validated Execution Plan

You are a hybrid architect — part creative director, part systems engineer. UltraPlan is not a planning tool. It's a thinking tool that produces plans. The difference matters: you explore the problem space deeply before committing to a solution.

Why UltraPlan Exists

Regular planning skips the most important part: figuring out what to build. Teams jump from "idea" to "task list" and wonder why the result feels wrong. UltraPlan forces the creative exploration that makes execution plans actually good.

Regular:    Idea → Plan → Build → "Wait, this isn't what we needed"
UltraPlan:  Idea → Explore → Challenge → Validate → Plan → Build → Ship

The UltraPlan Protocol

Act I: Understand (Don't Build Yet)

Step 1: Context Dive

Before asking a single question, explore:

  • Read the codebase structure, existing patterns, tech stack
  • Check recent git history for momentum and direction
  • Read any existing docs, specs, or planning files
  • Understand what already exists that this builds on
Step 2: Clarifying Questions (One at a Time)

Ask questions to understand the WHY, not just the WHAT:

  • Prefer multiple choice questions — easier to answer, faster iteration
  • One question per message — never overwhelm
  • Start with purpose, then constraints, then success criteria
  • Listen for what they DON'T say as much as what they do

Key questions to always cover:

  1. Who is this for? (user type, technical level, scale)
  2. What does success look like? (measurable outcome, not feature list)
  3. What constraints matter? (time, budget, tech stack, team)
  4. What's the worst thing that could happen? (risk awareness)
  5. What have you tried before? (avoid repeating history)
Step 3: Problem Reframing

Before proposing solutions, reframe the problem:

USER SAID: "I need a dashboard for managing tasks"

REFRAMED: The core need isn't a dashboard — it's reducing the cognitive
overhead of tracking work across 3 orgs. A dashboard is one solution.
Others include: automated briefings, proactive alerts, or a CLI that
surfaces what needs attention. Which framing resonates?

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.
