smarthome-mcp-lab: Command for Claude Code

.claude/commands/core_piv_loop/prime.md

prime is a command for Claude Code from jui-hung-yuan/smarthome-mcp-lab. It costs 6 tokens per session (365 once invoked), scanned A, a copy of prime, MIT.

A command that builds a working understanding of a software project by examining its files, documentation, configuration, and recent Git history.

In plain words
What is it for?
Use it at the start of a coding task to identify entry points, key files, technologies, project rules, and recent changes.
Why use it?
It reduces the time an agent spends guessing how an unfamiliar codebase is organised and what state it is in.

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

prime 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 10d 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.

Origin

This is a copy

100% identical to prime — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Prime: Load Project Context

Objective

Build comprehensive understanding of the codebase by analyzing structure, documentation, and key files.

Process

1. Analyze Project Structure

List all tracked files: !git ls-files

Show directory structure: On Linux, run: tree -L 3 -I 'node_modules|__pycache__|.git|dist|build'

2. Read Core Documentation

  • Read CLAUDE.md or similar global rules file
  • Read README files at project root and major directories
  • Read any architecture documentation

3. Identify Key Files

Based on the structure, identify and read:

  • Main entry points (main.py, index.ts, app.py, etc.)
  • Core configuration files (pyproject.toml, package.json, tsconfig.json)
  • Key model/schema definitions
  • Important service or controller files

4. Understand Current State

Check recent activity: !git log -10 --oneline

Check current branch and status: !git status

Output Report

Provide a concise summary covering:

Project Overview

  • Purpose and type of application
  • Primary technologies and frameworks
  • Current version/state

Architecture

  • Overall structure and organization
  • Key architectural patterns identified
  • Important directories and their purposes

Tech Stack

  • Languages and versions
  • Frameworks and major libraries
  • Build tools and package managers
  • Testing frameworks

Core Principles

  • Code style and conventions observed
  • Documentation standards
  • Testing approach

Current State

  • Active branch
  • Recent changes or development focus
  • Any immediate observations or concerns

Make this summary easy to scan - use bullet points and clear headers.

Changes

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.
