codex-spec-interviewer

codex-spec-interviewer is a skill for Codex from stark-ai-de/agent-skills. It costs 102 tokens per session (2,579 once invoked), scanned A, original, Apache-2.0.

An interview workflow that turns an unclear coding request into a verified specification for Codex. It defines requirements, assumptions, architecture decisions, acceptance criteria, validation, and a bounded plan before implementation.

In plain words
What is it for?
Use it before implementing a feature, bug fix, refactor, migration, or architecture change when the request is incomplete or involves trade-offs. The resulting specification gives Codex concrete instructions to follow.
Why use it?
It reduces misunderstandings and scope changes during larger coding tasks. It also makes important technical decisions explicit and checks them against the repository and current sources.

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

codex-spec-interviewer 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 today.

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.

Codex Spec Interviewer

Goal

Produce a user-verified implementation spec that Codex can execute with minimal ambiguity, minimal scope creep, explicit validation, explicit assumptions, a bounded source challenge, and ADRs for durable architectural decisions when needed. Save every final spec using the repo's clear convention or a confirmed destination; save ADR files only when the ADR gate requires one.

This is one end-to-end outcome, not a public multi-workflow skill. Do not invent review/save variants or add a workflow-selection checkpoint.

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.
  • File layout, naming conventions, scripts, package manager, lint/test/type-check commands, and CI expectations.
  • Current framework, library, API, or platform documentation through available MCP tools or web search when a decision depends on up-to-date behavior.
  • Error messages, screenshots, logs, PR feedback, or example files the user supplied.

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.
