feasibility-assessorEvaluates whether a business idea is technically buildable and financially viable.
Feasibility Assessor is an agent skill from Mathews-Tom/armory. Evaluates whether a business idea is technically buildable and financially viable. Covers unit economics (CAC, LTV), revenue modeling, break-even, and go/no-go verdicts. Triggers on: "feasibility assessment", "viability analysis", "unit economics", "build vs buy", "go/no-go decision", "ROI projection".
Its SKILL.md is about 2.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `evals/cases.yaml`, `references/financial-viability.md` and `references/technical-risk.md`).
It sits in Business, Finance & HR, covering Financial modeling and Feature launches and release readiness. The repository describes itself as: Curated, production-grade skills for AI coding agents. Battle-tested workflows for developers who use AI seriously. The licence is MIT.
5 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 4594fb7. It shows what the files ask for, not the result of running them.
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.
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.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Feasibility Assessor loads about 2.1k tokens when it runs, and up to ~9k if it reads all its reference files. Until then it costs about 81 tokens; SKILL.md has 872 words of instructions outside code blocks.
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.
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.

This skill also uses 4 other files; get the full folder from GitHub.Evaluate business ideas and features across two tracks: financial viability and technical feasibility. Produce an integrated verdict with actionable de-risking recommendations.
Determine the input type:
Extract from the input:
If critical inputs are missing, ask targeted clarifying questions before proceeding. Minimum viable inputs: value proposition and target customer.
Reference: references/unit-economics.md, references/financial-viability.md
Skip this phase only when the request is purely technical (e.g., "can we build X with Y stack").
State every assumption explicitly. Flag assumptions with high sensitivity (small change flips the outcome).
Reference: references/technical-risk.md
Skip this phase only when the request is purely financial (e.g., "are the unit economics viable for a SaaS at $29/mo").
Classify complexity:
| Level | Description | Examples |
|---|---|---|
| 1 — Simple | Standard CRUD, single service | Landing page, basic CMS, form-based app |
| 2 — Moderate | Multi-service integration, auth, payments | E-commerce, SaaS dashboard, API platform |
| 3 — Complex | Distributed systems, real-time, high availability | Marketplace, streaming platform, fintech |
| 4 — Novel | R&D required, unproven at scale | ML-driven product, novel protocol, hardware+software |
Evaluate:
Score each dimension 1-5 (1 = low risk, 5 = critical risk):
| Dimension | What It Measures |
|---|---|
| Technical novelty | Proven tech (1) vs active R&D required (5) |
| Integration complexity | Self-contained (1) vs many external APIs (5) |
| Scale readiness | Architecture handles 100x with config changes (1) vs requires re-architecture (5) |
| Data risk | Public/owned data, no regulation (1) vs restricted data, heavy compliance (5) |
| Security/compliance | No sensitive data (1) vs PCI/HIPAA/SOC2 required (5) |
Composite technical risk = weighted average. Flag any dimension scoring 4+ as a blocker requiring mitigation plan.
| Financial | Technical | Verdict |
|---|---|---|
| Viable | Straightforward | Green — proceed |
| Viable | Challenging | Yellow — proceed with caution, mitigate tech risks |
| Risky | Straightforward | Yellow — validate financial assumptions first |
| Risky | Challenging | Yellow — high uncertainty, run cheap experiments |
| Not viable | Any | Red — reconsider fundamentals |
| Any | High-risk/Research | Red — reduce technical unknowns before committing |
Identify the top 3-5 assumptions that most influence the verdict. For each, state:
Rank experiments by cost-to-run vs information-value. Prioritize experiments that validate the riskiest assumptions at the lowest cost.

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Mathews-Tom/armory --skill feasibility-assessor -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/feasibility-assessor, .gemini/skills/feasibility-assessor, .github/skills/feasibility-assessor and .opencode/skills/feasibility-assessor in your project.
SKILL.md names no scripts, command-line tools or credentials: Feasibility Assessor is instructions for the agent only.
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.
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.
Feasibility Assessor is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.1k tokens (SKILL.md is roughly 8.5k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 6.9k tokens, read only when the agent opens those files.
