feature-planning

feature-planning is a skill for Claude Code, Codex from dagba/ios-mcp. It costs 30 tokens per session (841 once invoked), scanned A, original, MIT.

A method for turning feature requirements into an implementation plan. It identifies goals, screens, data flows, integrations, architecture, tasks, and risks.

In plain words
What is it for?
For analyzing new features, choosing an architecture, breaking work into foundation, logic, interface, integration, and quality tasks, and assessing risks.
Why use it?
It helps prevent missing work or choosing an unsuitable structure before coding begins. It also makes large requests easier to divide into stages with acceptance criteria.

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 6d 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.

Feature Planning

Overview

Systematic approach to decompose features into actionable tasks. For senior engineers who know how to code but need a structured thinking framework.

Quick Workflow

1. Requirement Analysis

  • Clarify user goal and acceptance criteria
  • Identify screens, data flows, integration points
  • Ask: API ready? Design assets available? Platform requirements?

2. Choose Architecture

Use architecture-patterns skill to decide:

  • Simple (1-2 screens, local state) → MV
  • Medium (3-5 screens, business logic) → MVVM
  • Complex (state machines, side effects) → TCA
  • Enterprise (multi-team) → Clean Architecture

3. Task Breakdown Structure

Phase 1: Foundation

  • Models/entities
  • API client stubs
  • Navigation structure

Phase 2: Core Logic

  • ViewModels/Reducers
  • Business rules
  • State management

Phase 3: UI

  • Layouts and components
  • Styling and animations
  • Loading/error states

Phase 4: Integration

  • Wire up ViewModels to Views
  • Connect to backend
  • Handle edge cases

Phase 5: Quality

  • Unit tests (ViewModels, business logic)
  • UI tests (critical flows)
  • Accessibility audit

4. Risk Assessment

Risk Mitigation
Unknown APIs Define contract early, use mocks
New technology POC spike first, allocate learning time
Performance concerns Profile early, plan caching/pagination
Tight deadline Negotiate scope, identify MVP

5. Estimation

Rule of Thumb: Sum task estimates + 30-50% buffer

Break tasks into <1 day chunks. If a task feels >1 day, decompose further.

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.

feature-planning is a skill published in the GitHub repository dagba/ios-mcp (3 stars, last pushed 7mo ago), licensed MIT. It adds 30 tokens to every session and 841 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 2026-08-31.
