mk:plan-creator

mk:plan-creator is a skill for Claude Code from ngocsangyem/MeowKit. It costs 93 tokens per session (4,886 once invoked), scanned A, original, MIT.

A planning workflow that creates a structured, multi-file implementation plan before development begins. It adjusts the amount of research and detail to the size and complexity of the task.

In plain words
What is it for?
Classifying tasks, inspecting the project, recording unresolved decisions, drafting plan files, validating the plan, and preparing plans for product builds or tasks involving several files.
Why use it?
It turns a non-trivial request into an agreed sequence of work, decisions, and validation steps. This reduces the chance of starting implementation with unclear scope or missing prerequisites.

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

mk:plan-creator 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.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/check-product-spec.sh, scripts/validate-plan.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 252 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Plan Creator

Public surface: classify → inspect → capture missing decisions → draft → validate → Gate 1. Produces plan.md overview + phase-XX detail files; execution, existing-plan audits, visual rendering, archive, and durable-memory capture stay with their existing owners.

When to Use

Activate when:

  • User runs /mk:plan [task] or /mk:cook [task]
  • Non-trivial task (> 2 files OR > 1h OR architectural decisions)
  • User supplies ≥2 upstream reports/specs (office-hours, brainstorming, planning-engine, confluence-spec, intake output…) → step-00.5 consolidates them into a Plan Intake Packet before planning (see references/plan-intake-packet.md)
  • User supplies a design evidence packet (e.g. from mk:figma) → plan consumes it (viewport/state ACs, critical-action validation matrix, phase blocked_on: for high-risk flow ambiguity), never re-analyzes the design source (see references/design-evidence-consumption.md)
  • Gate 1 requires a plan before Phase 3
  • Green-field product build ("build a kanban app", "create a SaaS dashboard", "make a retro game maker") → step-00 auto-detects and offers --product-level
  • Existing-plan audit → mk:validate-plan; archive → lifecycle CLI; visual rendering → mk:visual-plan.
  • Hard/deep plan creation still runs its built-in red-team and validation interview before Gate 1. These are design-quality gates, not standalone subcommands, and must never be routed away.
  • Compatibility aliases: /mk:plan archive → archive workflow; /mk:plan red-team {path} → standalone red-team workflow; /mk:plan validate {path} → standalone validation workflow.

Standalone aliases route to their compatibility references; they do not replace hard/deep red-team or validation. --html routes to mk:visual-plan.

Skip when:

  • /mk:fix with complexity=simple (Gate 1 exception)
  • mk:scale-routing returns workflow=one-shot + zero blast radius

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.
