What it does

Before You Build is an agent skill from sickn33/agentic-awesome-skills. Review product risk before coding by checking demand, alternatives, channels, switching costs, and failure signals.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: AAS Core is the local, agent-first control plane for complete catalog discovery, agent-owned selection, stack validation, and planning, backed by 2,400+ agentic skills. Includes… The licence is MIT.

Example prompts

  • “/before-you-build”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Identify the Build Bet
  2. Check the Main Risks
  3. Decide the Next Small Test
  4. Continue or Stop

What it can do on your machine

Read from SKILL.md and the folder at commit 680176d. 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.

    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

Before You Build loads about 1.2k tokens when it runs. Until then it costs about 33 tokens; SKILL.md has 563 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~33
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

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.

Before You Build

Overview

Before You Build helps an AI coding workflow pause before implementation and check whether the feature, product, or tool is worth building. It focuses on product risk rather than code structure: who needs the thing, what they use today, why they would switch, how distribution works, and what evidence would make the project safer to start.

The upstream project ships a standalone skill repository and an npx installer for several coding assistants.

When to Use This Skill

  • Use when a user asks an AI coding assistant to build a new app, feature, internal tool, SaaS, or side project.
  • Use when the idea sounds plausible but the buyer, workflow, distribution path, or switching reason is still vague.
  • Use before writing code so the assistant can turn the request into sharper assumptions, risk checks, and validation steps.

How It Works

Step 1: Identify the Build Bet

Restate the product or feature in one concrete sentence. Name the intended user, the job they are trying to finish, and the current workaround or competitor.

Step 2: Check the Main Risks

Review the idea across demand, workflow fit, willingness to switch, distribution, pricing, data access, and operational burden. Prefer specific doubts over generic brainstorming.

Step 3: Decide the Next Small Test

Suggest the smallest useful validation step before implementation. This could be a buyer conversation, landing page test, manual concierge workflow, prototype, waitlist, paid pilot, or narrow internal trial.

Step 4: Continue or Stop

If the risk is acceptable, move into implementation with the assumptions written down. If the risk is high or evidence is weak, recommend a smaller experiment instead of building the full version.

Examples

Example 1: SaaS Feature Request
text
User: Build a dashboard for AI trend monitoring.

Before coding, check:
- Which role needs this dashboard every week?
- What source do they use today?
- What decision changes because of the dashboard?
- Would they pay for alerts, reports, or workflow integration?
- What is the smallest manual report that proves repeat use?
Example 2: Internal Tool
text
User: Build an internal CRM for our small team.

Before coding, check:
- What breaks in the current spreadsheet or existing CRM?
- How many people will use it daily?
- What data must be imported or kept in sync?
- What process change is required after launch?
- Can a no-code workflow prove the need first?

Best Practices

  • ✅ Ask for the user, job, current alternative, and switching reason before implementation.
  • ✅ Separate product risk from engineering risk so the team does not solve the wrong problem well.
  • ✅ Recommend small validation steps when the idea has weak demand evidence.
  • ✅ Keep product names, numbers, and claims grounded in what the user provides.
  • ❌ Do not present a generic checklist as proof that an idea is validated.
  • ❌ Do not fabricate market size, revenue, competitor traction, or buyer quotes.

Limitations

  • This skill does not replace customer research, legal review, financial advice, or domain expert review.
  • It cannot prove demand by itself; it helps the assistant surface assumptions and choose a smaller validation step.
  • If the user already has strong evidence and a clear spec, keep the review short and move into implementation.

Security & Safety Notes

  • This skill is safe to run as a planning layer because it does not require credentials, external network access, or file mutation.
  • If paired with an installer or repository fetch, only install from the upstream repository or npm package you trust.

Common Pitfalls

  • Problem: The assistant repeats the product pitch instead of challenging the assumptions. Solution: Ask for current alternatives, switching triggers, and a validation step before code.

  • Problem: The review becomes too broad and blocks progress. Solution: Pick the riskiest assumption and test only that first.

  • Problem: The idea is treated as a startup even when it is a small internal workflow. Solution: Scale the risk review to the project size and only ask questions that change the build decision.

  • @saas-mvp-launcher - Use when moving from validation into MVP planning and launch execution.
  • @ux-research-methodology - Use when the next step needs structured user research.
