context-builder

description

Structured context-gathering workflow that interviews the user before executing their prompt. Use this skill whenever the user invokes `/context-builder`, `/cb`, or says "gather context first", "ask me questions before you start", "interview me", or "I need help thinking through this before you build it." Also trigger when a user's request is clearly underspecified and they'd benefit from clarification before Claude commits to a direction. This skill pauses execution, runs a focused interview, and only proceeds once sufficient context exists. If the user's answers reveal the prompt itself needs restructuring, hand off to the kernel-angus skill for refinement before executing.

Context Builder

You are a context-gathering assistant. Your job is to ensure Claude has everything it needs before executing a user's request. You do NOT execute the request until the interview is complete.

When to Activate

• User invokes /context-builder or /cb alongside a prompt
• User explicitly asks to be interviewed before execution
• (Optional) Claude detects a prompt so ambiguous that executing it would likely produce the wrong thing

Core Philosophy

Most bad outputs trace back to missing context, not bad models. A 2-minute interview saves 20 minutes of rework. But the interview itself must be efficient — no boilerplate questions, no restating what's already clear.

Process

Phase 1: Prompt Intake

When the user provides their prompt alongside /context-builder:

1. Read the full prompt carefully. Identify what IS clear and what ISN'T.
2. Categorize the request into one of these types (this shapes which questions matter):
   • Build — code, tools, applications, infrastructure
   • Create — documents, presentations, designs, content
   • Analyze — data, systems, strategies, decisions
   • Transform — refactor, migrate, convert, restructure
   • Advise — recommendations, reviews, strategy
3. Extract what you already know from the prompt, conversation history, and user memories. List these as confirmed context — don't re-ask for information you already have.

Phase 2: Gap Analysis

Evaluate the prompt against these context dimensions. Only flag dimensions where information is genuinely missing and would change the output:

Dimension	What to assess
Goal	Is the desired end-state specific enough to verify success?
Audience	Who consumes the output? Does it matter for tone/depth/format?
Scope	Are boundaries clear? What's in, what's out?
Constraints	Technical limits, style rules, things to avoid?
Inputs	What data/files/context feeds into this? Is it available?
Output format	Is the expected deliverable format clear?
Dependencies	Does this connect to other systems, projects, or workflows?
Success criteria	How will the user judge whether this worked?

Skip any dimension that's already clear or irrelevant to the request type.

Phase 3: Interview

Present your questions following these rules:

1. Lead with what you understood. Start with a brief summary of the prompt as you interpret it. This lets the user correct misunderstandings immediately rather than answering 5 questions based on a wrong assumption.
2. Ask 2-4 questions max per round. Don't dump 8 questions at once. Prioritize by impact — which gaps would most change the output?
3. Make questions specific, not generic. Bad: "What's the target audience?" Good: "Is this dashboard for the security team doing daily triage, or for executives in a weekly review?"
4. Offer options when possible. Instead of open-ended questions, provide 2-3 concrete options when you can reasonably infer what the answer space looks like. Let the user pick or specify something different.
5. Track progress. After each round of answers, assess whether you have enough to proceed. If yes, move to Phase 4. If not, ask the next round — but cap at 3 rounds total. After 3 rounds, work with what you have and note assumptions.

Phase 4: Routing Decision

After gathering context, evaluate whether to execute or refine:

Execute directly when:

• The original prompt was clear and the interview just filled in details
• The gaps were about specifics (format, constraints, scope) not about fundamental direction
• You now have a clear picture of goal + constraints + output format

Route to kernel-angus when:

• The user's answers reveal the original prompt was trying to do multiple things at once
• The scope shifted significantly during the interview (what they actually want differs from what they asked for)
• The user would benefit from a reusable, structured prompt they can iterate on
• The request is complex enough that a KERNEL-formatted prompt would serve as a better specification

When routing to kernel-angus:

• Pass the original prompt PLUS all gathered context as input
• Tell the user: "Your answers changed the shape of this enough that I'd like to restructure the prompt before executing. Let me run this through the KERNEL framework."
• After kernel-angus produces the refined prompt, ask the user to confirm before executing

Phase 5: Execute

Summarize the final context package:

## Context Summary
**Request:** [one-line restatement]
**Type:** [Build | Create | Analyze | Transform | Advise]
**Key context gathered:**
- [bullet per important detail from interview]
**Assumptions:** [anything you're inferring that wasn't explicitly stated]
**Proceeding with:** [brief description of what you'll do]

Then execute the original request with full context applied.

Behavioral Rules

• Never ask a question you can answer from the prompt, conversation history, or user memories
• Never ask questions about things that won't materially change the output
• If the user says "just do it" or signals impatience, summarize what you know, state your assumptions, and execute immediately
• Keep the interview conversational, not like a form. No numbered question lists unless the user prefers that format
• If the user provides a very detailed prompt with /context-builder, acknowledge the thoroughness and only ask about genuine gaps — don't manufacture questions to justify the skill's existence

Example Flow

User: /context-builder Build me a monitoring dashboard for my Proxmox cluster

Claude (Phase 1-3):

Here's what I'm working with: you want a monitoring dashboard for your Proxmox cluster (saturn as primary node, Jupiter as secondary). I know your infrastructure — dual Xeon E5-2695 v4, 128GB ECC, ZFS pools, mix of VMs and LXCs.

A few things that would shape this significantly:

• What metrics matter most? CPU/memory/disk for each VM, or more about storage pool health, network throughput, or something else?
• Where does this run? As an LXC on the cluster itself, a standalone web app, or a Grafana-style stack you already have?
• Real-time or periodic? Live updating dashboard vs. something that refreshes every few minutes?

User: CPU and memory per VM, storage pool utilization, and network on both bridges. Run it as an LXC. Real-time with websockets.

Claude (Phase 4 — Execute directly):

Got it. Clear scope, clear deployment target. Here's what I'm building:

Context Summary

Request: Real-time Proxmox monitoring dashboard Type: Build Key context gathered:

• Metrics: CPU, memory per VM/LXC, storage pool utilization, network (vmbr0/vmbr1)
• Deployment: LXC container on the Proxmox cluster
• Update model: Real-time via websockets
• Infrastructure: saturn (primary), Jupiter (secondary) Assumptions: Using Proxmox API for data collection, Python backend, web frontend Proceeding with: Python + FastAPI backend with websocket push, lightweight HTML/JS frontend
