tfx-interview

tfx-interview is a skill for Claude Code from tellang/triflux. It costs 52 tokens per session (3,123 once invoked), scanned A, original, MIT.

A question-driven workflow for turning a vague implementation request into specific requirements. It measures ambiguity—how much the goal, constraints, and success criteria are unclear—and asks questions to reduce it.

In plain words
What is it for?
Use it to clarify a feature or project, define constraints and success criteria, find edge cases, and produce a more actionable starting specification.
Why use it?
It exposes missing conditions and boundaries before coding begins, helping avoid building too much or too little.

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

tfx-interview 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 8d 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.

tfx-interview — Quantified Socratic Requirements Exploration

라우팅 정본 D2는 .claude/rules/tfx-routing.md를 따른다.

ARGUMENTS 처리: 이 스킬이 ARGUMENTS: <값>과 함께 호출되면, 해당 값을 사용자 입력으로 취급하여 워크플로우의 첫 단계 입력으로 사용한다. ARGUMENTS가 비어있거나 없으면 기존 절차대로 사용자에게 입력을 요청한다.

OMC deep-interview + ouroboros 오마주. 모호성을 숫자로 측정하고 20% 미만까지 질문한다. "측정할 수 없으면 개선할 수 없다."

Antigravity 위임: 분석·점수 계산·산출물 초안은 Antigravity CLI에 위임하여 Claude 토큰을 절약한다. 위임 패턴: Bash("TFX_CLI_MODE=antigravity bash ~/.claude/scripts/tfx-route.sh antigravity '{prompt}'")

위임 패턴

Claude와 Antigravity의 역할을 분리하여 토큰을 최적화한다.

담당 작업
Claude AskUserQuestion (사용자 상호작용), 최종 파일 저장
Antigravity 모호성 점수 계산, 질문 생성, 응답 분석, 산출물 초안
# 위임 호출 형태
Bash("TFX_CLI_MODE=antigravity bash ~/.claude/scripts/tfx-route.sh antigravity '{prompt}'")

Antigravity 실패 시 Fallback: Claude Opus가 분석을 직접 처리한다.

용도

  • 구현 전 요구사항 명확화
  • 모호한 요청을 정량적으로 분석하여 실행 가능한 수준으로 구체화
  • 빠진 제약 조건, 성공 기준, 경계 조건을 체계적으로 발견
  • 과잉 구현/과소 구현 방지

핵심: 모호성 점수 (Ambiguity Score)

요구사항의 모호성을 수학적으로 측정한다:

ambiguity = 1 - (goal × 0.40 + constraints × 0.30 + criteria × 0.30)

각 요소 (0.0 ~ 1.0):
  goal       — 목표 명확도. "무엇을 달성하려는가?"가 명확한가?
  constraints — 제약 조건 명확도. 범위, 기술 스택, 시간, 호환성 등
  criteria   — 성공 기준 명확도. "어떻게 되면 완료인가?"

예시:
  입력: "인증 기능 추가해"
  goal = 0.5 (인증이 무슨 인증? OAuth? JWT? 세션?)
  constraints = 0.2 (기술 스택? 기존 시스템 연동?)
  criteria = 0.1 (테스트? 성능? 보안 수준?)
  ambiguity = 1 - (0.5×0.40 + 0.2×0.30 + 0.1×0.30) = 1 - 0.29 = 0.71 (71%)

목표: ambiguity < 0.20 (20% 미만)이 될 때까지 질문 반복.

워크플로우

Step 1: 초기 모호성 평가

사용자 입력을 Antigravity에 전달하여 초기 ambiguity score를 계산한다:

# Claude → Antigravity 위임
Bash("TFX_CLI_MODE=antigravity bash ~/.claude/scripts/tfx-route.sh antigravity 'Analyze the following requirement and calculate ambiguity score. Return JSON: {goal, constraints, criteria, ambiguity, suggested_questions}: {user_input}'")

Antigravity가 반환한 JSON에서 점수를 읽어 사용자에게 표시한다:

출력 예시:
  "📊 현재 모호성: 71%
   - 목표: 50% 명확 (어떤 인증 방식?)
   - 제약: 20% 명확 (기술 스택 미정)
   - 기준: 10% 명확 (완료 조건 없음)
   → Stage 1: Clarify부터 시작합니다."

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.

tfx-interview is a skill published in the GitHub repository tellang/triflux (7 stars, last pushed 6d ago), licensed MIT. It adds 52 tokens to every session and 3,123 once invoked, about $0.0003 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.
