attune-ai: Skill for Claude Code

.agents/skills/planning/SKILL.md

planning is a skill for Claude Code, Codex from Smart-AI-Memory/attune-ai. It costs 32 tokens per session (609 once invoked), scanned A, original, Apache-2.0.

A planning tool for software work, including new features, test-driven development (TDD), and architecture reviews. TDD means designing tests before writing the code they check.

In plain words
What is it for?
Use it to plan a feature, choose a TDD approach, or review the structure of a system. It is intended for decisions about what to build and how to organize it.
Why use it?
It helps turn a broad development request into a clearer approach before implementation begins. It can also use documents in a file or directory as research for the plan.

Written for no agent in particular: nothing here depends on one. Also seen: names the AskUserQuestion tool; installed under .agents/ (shared by several agents).

This is Smart-AI-Memory/attune-ai's own configuration. It tells Claude Code and Codex how to work on attune-ai itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything attune-ai configures →

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

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 7d 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.

How it starts

The opening of the file, as written. The whole thing — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Planning

IMPORTANT: Start your response with a context preamble.

Call help_lookup(topic="spec-engine", mode="preamble") and display the returned preamble text as a blockquote. Then tell the user they can say "tell me more" for a step-by-step guide, or answer the scoping questions below to proceed.

If the MCP call fails, fall back to:

Planning — Helps you plan features, architecture, and TDD strategy before writing code.

High-level development planning and architecture design.

tdd Plan TDD approach
architecture Architecture review

MCP Tools

Tool What It Does
research_synthesis Synthesize insights from source documents at a path to inform planning

Use research_synthesis when the user needs to gather context from a directory of files or docs before planning. Pass the directory (or file) as path; optionally set depth to quick, standard, or deep:

research_synthesis(path="<dir or file>", depth="standard")

Scoping

Before running, ask:

  1. Type: "What kind of planning? Feature spec, TDD approach, or architecture review?"
  2. Subject: Depending on type:
    • Feature: "What feature? What problem does it solve?"
    • TDD: "What behavior should the tests verify?"
    • Architecture: "What system? Any specific concerns?"
  3. Scope: "How deep? Quick outline or detailed plan?"

Surface. The Subject phrasing branches on Type, so don't batch all three — ask Type first (a single AskUserQuestion) when it isn't already given by the <what to plan> argument. Once the type is known, Subject (a textarea) and Scope (quick / detailed) are independent and open: gather those two as one form via the elicit skill, preferring the rich widget surface (elicitation_render_widgetshow_widget) with the AskUserQuestion mapping as fallback. If only one dimension is open, ask it as a single question — never force a one-field form (the §4 batching rule).

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.

planning is a skill published in the GitHub repository Smart-AI-Memory/attune-ai (10 stars, last pushed yesterday), licensed Apache-2.0. It adds 32 tokens to every session and 609 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.
