사이드프로젝트 기술스택을 체계적으로 비교·선정하는 의사결정 매트릭스. An agent skill from revfactory/harness-100.

  • Databases work in your project
  • SKILL.md covers 평가 기준 프레임워크 (5축), 프론트엔드 비교, 백엔드 비교 and 데이터베이스 비교, plus 4 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Techstack Decision Matrix is an agent skill from revfactory/harness-100. 사이드프로젝트 기술스택을 체계적으로 비교·선정하는 의사결정 매트릭스. 'techstack-analyst' 에이전트가 기술스택을 비교하고 추천할 때 이 스킬의 평가 기준, 비용 계산법, 스택 조합 패턴을 반드시 활용해야 한다. '기술스택 비교', '인프라 비용 계산', '스택 선정' 등에 사용한다. 단, 시장 분석이나 MVP 설계는 이 스킬의 범위가 아니다.

Its SKILL.md is about 900 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Databases. It works with SQL and Next.js. The licence is Apache-2.0.

When your agent uses it

  • Databases work in your project

Example prompts

  • “techstack-analyst”
  • “/techstack-decision-matrix”

What it can do on your machine

Read from SKILL.md and the folder at commit 8e8d35c. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Techstack Decision Matrix loads about 903 tokens when it runs. Until then it costs about 57 tokens; SKILL.md has 246 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~57
When it runs · the whole SKILL.md, loaded when a task matches
~903

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Or copy the skill folder (ko/79-side-project-launcher/.claude/skills/techstack-decision-matrix in revfactory/harness-100) into .agents/skills/techstack-decision-matrix in your project. Codex loads it when a task matches its description.

Can I use Techstack Decision Matrix in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add revfactory/harness-100 --skill techstack-decision-matrix -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/techstack-decision-matrix, .gemini/skills/techstack-decision-matrix, .github/skills/techstack-decision-matrix and .opencode/skills/techstack-decision-matrix in your project.

What does Techstack Decision Matrix need to run?

SKILL.md names no scripts, command-line tools or credentials: Techstack Decision Matrix is instructions for the agent only.

Does Techstack Decision Matrix access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Techstack Decision Matrix safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Techstack Decision Matrix use?

Techstack Decision Matrix is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Techstack Decision Matrix use?

About 903 tokens (SKILL.md is roughly 3.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Techstack Decision Matrix?

Skills that share tags, products or a category with Techstack Decision Matrix: Next Supabase Vercel Bundle (LeoYeAI/openclaw-master-skills, 2.2k stars), SQL Database Support for pREST (prest/prest, 4.6k stars), Crud (wujun728/jun_java_plugin, 240 stars) and Npgsqlrest (NpgsqlRest/NpgsqlRest, 132 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
