feature-planning

feature-planning is a skill for Claude Code, Codex from nicepkg/ai-workflow. It costs 21 tokens per session (1,834 once invoked), scanned A, original, MIT.

A workflow wrapper that turns prior research files into a structured implementation plan. It checks project instructions and research context before creating the plan.

In plain words
What is it for?
Use it after research to verify project files, read the available research, create a named feature plan, and validate the resulting planning files.
Why use it?
It keeps planning tied to existing research and required project conventions. This reduces the risk of planning from incomplete context or skipping required checks.

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

feature-planning 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.

Feature Workflow: Plan Implementation

YOU ARE READING THIS SKILL RIGHT NOW

STOP. Before doing ANYTHING else:

  1. ☐ Create TodoWrite checklist (see below)
  2. ☐ Mark Step 1 as in_progress
  3. ☐ Read CLAUDE.md first (if exists)

This skill is a WRAPPER that loads Z01 context and invokes superpowers:writing-plans

MANDATORY FIRST ACTION: Create TodoWrite

TodoWrite({
  todos: [
    {content: "Step 1: Load project context (CLAUDE.md if exists)", status: "in_progress", activeForm: "Reading CLAUDE.md"},
    {content: "Step 2: Verify Z01 files exist", status: "pending", activeForm: "Checking research"},
    {content: "Step 3: Read ALL Z01 files", status: "pending", activeForm: "Loading context"},
    {content: "Step 4: Invoke superpowers:writing-plans", status: "pending", activeForm: "Creating plan"},
    {content: "Step 5: Verify Z02 outputs", status: "pending", activeForm: "Validating output"}
  ]
})

After each step: Mark completed, move in_progress to next step.

Why Use This Wrapper?

  • Automates Z01 → Z02 file management
  • Loads CLAUDE.md constraints into planning context
  • Enforces feature-workflow naming conventions (Z02_{feature}_plan.md)
  • Integrates with clarification workflow (Z02_CLARIFY)
  • Maintains consistent file structure

Without this wrapper: You'd manually load Z01 files, pass to superpowers:writing-plans, manage Z02 output paths, check for clarifications.

Workflow Steps

Step 1: Load Project Context (MANDATORY FIRST)

Read CLAUDE.md if it exists.

Extract from CLAUDE.md (if exists):

  • Mandatory patterns that MUST be preserved
  • Forbidden approaches to AVOID
  • Project conventions (naming, structure, etc.)
  • Release workflows and constraints

CRITICAL: If CLAUDE.md exists and contains constraints, these MUST be passed to superpowers:writing-plans so the plan preserves project standards.


Step 2: Verify Z01 Files Exist

Scan for existing Z01 files in common locations (docs/ai/ongoing, .ai/ongoing, docs/ongoing).

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.
