# codex-spec-interviewer

Converts ambiguous feature requests into verified implementation specs and ADRs before any code is written. Ideal when a task spans multiple files and requires clear acceptance criteria.

## What it does

This skill runs a structured interview to resolve material unknowns, checking assumptions against your repository docs and external APIs. It outputs testable acceptance criteria, validation commands, and necessary architectural decision records directly to an agreed file path.

All interview discovery remains strictly read-only, preventing unintended repo edits while in Plan mode. There are no bundled scripts. Crucially, the skill never implements the features itself; it finishes by delivering a ready-to-run Codex execution prompt.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add stark-ai-de/agent-skills --skill codex-spec-interviewer -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/codex-spec-interviewer/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/codex-spec-interviewer/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add stark-ai-de/agent-skills --skill codex-spec-interviewer -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/codex-spec-interviewer/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add stark-ai-de/agent-skills --skill codex-spec-interviewer -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/codex-spec-interviewer/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install stark-ai-de/agent-skills codex-spec-interviewer
```

2. **Manually: put the files in place**
- File: `.github/skills/codex-spec-interviewer/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add stark-ai-de/agent-skills --skill codex-spec-interviewer -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/stark-ai-de/agent-skills --path skills/codex-operations/codex-spec-interviewer
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/codex-spec-interviewer/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add stark-ai-de/agent-skills --skill codex-spec-interviewer -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/stark-ai-de/agent-skills/tree/HEAD/skills/codex-operations/codex-spec-interviewer/SKILL.md

## When to use it
- produce detailed implementation specs for multi-file tasks
- capture architectural tradeoffs in ADRs before coding
- verify assumptions against repository code and live documentation
- generate explicit validation steps and Codex execution prompts

## Example prompts
- Interview me about the new webhook pipeline and draft an implementation spec
- Create an implementation spec and ADR for migrating our auth flow to Redis
- Help me specify acceptance criteria and validation commands for the billing export

# Codex Spec Interviewer

## Goal

Produce a user-verified implementation spec with bounded scope, testable acceptance criteria, source-backed decisions, validation, and any required ADRs. Deliver it to the agreed repository path, or in chat when explicitly requested. One approval covers the unchanged result and its concrete authorized writes.

This is one end-to-end workflow. A clear request selects it; do not invent review/save variants or add a workflow-selection checkpoint. For a bare invocation, ask for the task to specify.

## When to use

- The user has a rough idea but not a production-ready implementation spec.
- The task spans multiple files or concerns, or requires tradeoff decisions.
- The request needs acceptance criteria, validation commands, rollout notes, or risk handling.
- The user wants a reusable written artifact before implementation begins.
- Requirements, feature shape, ADR assumptions, or the implementation approach should be challenged against repo reality and current external sources before coding.

## When not to use

- The user already provided a complete implementation spec with files, constraints, tests, and acceptance criteria.
- The task is a tiny one-file edit without meaningful ambiguity.
- The user wants brainstorming only and no concrete implementation artifact.
- The user only wants `AGENTS.md` content or Codex memory entries authored, not an implementation spec.
- The task is primarily a policy, legal, or business-decision document.
- The user asks to audit or clean up Codex memory state; use a Codex memory skill instead.

## Inputs to inspect

- The current user request and any follow-up answers.
- Relevant `AGENTS.md`, `README.md`, issue descriptions, ADRs, repo docs, and `docs/agents/` files.
- Existing specs, plans, requirements, and PRDs the user wants preserved or challenged.
- A coordinated product-planning work item, when supplied: product/release/slice IDs, canonical contracts and revisions, prior answers, non-goals, evidence limits and genuine authorization. Do not require it for independent use.
- File layout, naming conventions, scripts, package manager, lint/test/type-check commands, and CI expectations.
