tfx-forge

tfx-forge is a skill for Claude Code from tellang/triflux. It costs 71 tokens per session (1,385 once invoked), scanned A, original, MIT.

A guided tool for creating or changing coding-agent skills. A skill is a documented workflow that tells an agent when and how to perform a recurring task.

In plain words
What is it for?
Use it to create a new skill, update an existing skill, or write a SKILL.md file with metadata, usage triggers, token expectations, workflow steps, and examples.
Why use it?
It reduces the work of designing skill instructions and keeping their structure consistent. It gathers requirements such as the skill type, triggers, workflow, and examples.

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-forge 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-forge — Skill Authoring Meta-Skill

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.

Superpowers skill authoring 오마주. 스킬을 만드는 스킬. "메타 레벨에서 자동화하라."

용도

  • 새 tfx 스킬의 SKILL.md를 대화형으로 생성
  • 기존 스킬 형식과 품질 기준을 자동 준수
  • YAML frontmatter + 본문 구조를 일관되게 유지
  • 스킬 작성 시행착오 최소화

워크플로우

Step 1: 요구사항 수집 (대화형)

AskUserQuestion으로 필수 정보를 순서대로 수집한다. 사용자가 초기 입력에 일부 정보를 포함했으면 해당 항목은 건너뛴다.

먼저 스킬 유형을 선택받는다:

AskUserQuestion:
  "스킬 유형을 선택하세요:"
  1. Light (경량, 단일 CLI, 토큰 절약)
  2. Deep (딥, 3-CLI 합의, 정확도 우선)
  3. Core (인프라, 다른 스킬이 내부 호출)

선택된 유형에 따라 이후 수집 항목과 템플릿이 달라진다:

  • Light: 단일 CLI 워크플로우, 낮은 토큰 예산
  • Deep: 3-CLI 병렬 + tfx-consensus 통합, 높은 토큰 예산
  • Core: 외부 호출 인터페이스 정의, 내부 API 문서화 포함

이후 나머지 정보를 순서대로 수집한다:

수집 항목 (순서대로):

1. 이름 (name)
   "스킬 이름은? (예: tfx-myskill)"
   → 접두사 'tfx-' 자동 부여 (없으면)

2. 한줄 설명 (description)
   "이 스킬이 무엇을 하는지 한 문장으로?"

3. 트리거 (triggers)
   "어떤 키워드로 이 스킬을 호출? (쉼표 구분)"

4. 토큰 예산
   "예상 토큰 예산은? (예: ~10K)"

5. 핵심 워크플로우
   "주요 단계를 간략히 설명해주세요. (3-5 단계)"

6. 사용 예시
   "사용 예시 1-3개를 알려주세요."

Step 2: 기존 스킬 분석

프로젝트 내 기존 SKILL.md를 참조하여 형식과 품질 기준을 확인한다:

Glob("skills/**/SKILL.md")로 기존 스킬 목록 수집
→ 유사한 타입(Deep/Light)의 스킬 1-2개를 Read하여 형식 참조
→ YAML frontmatter 구조, 본문 섹션 패턴, 토큰 예산 표 형식 추출

Step 3: SKILL.md 생성

수집된 정보로 SKILL.md를 자동 생성한다:

# YAML Frontmatter 템플릿
---
name: {name}
description: {description}
argument-hint: "{hint}"
---
# 본문 템플릿

# {name} — {short_title}

> {한줄 설명 또는 오마주}

## 용도

- {use_case_1}
- {use_case_2}
- {use_case_3}

## 워크플로우

### Step 1: {step_title}
{step_description}

### Step 2: {step_title}
{step_description}

...

## 토큰 예산

| 단계 | 토큰 |
|------|------|
| {step} | ~{N}K |
| **총합** | **~{total}K** |

## 사용 예

/{name} "{example_1}" /{name} "{example_2}"

Step 4: 디렉토리 생성 및 저장

mkdir -p skills/{name}/
Write → skills/{name}/SKILL.md

Step 5: 검증

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

tfx-forge is a skill published in the GitHub repository tellang/triflux (7 stars, last pushed 6d ago), licensed MIT. It adds 71 tokens to every session and 1,385 once invoked, about $0.0004 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.

ready

Make an unfamiliar repository agent-ready with a verify command, smoke tests, guardrails, and project notes. Use for repository setup, agentic engineering, verify commands, hooks, or allowlists; skip when verification and scope are already clear.

handoff

Write a state capsule so the next session — or a different agent/harness — can resume unfinished work without re-deriving context. Use when a session is ending with work incomplete, when the user says "handoff", "pack up", "ส่งต่อ", "continue tomorrow", when switching between Claude Code and Codex mid-task, or when…
