evaluate-startup

evaluate-startup is a skill for Claude Code from titusz/skills. It costs 156 tokens per session (2,072 once invoked), scanned A, original, MIT.

A research-based process for evaluating a startup or business idea and producing a scored analysis, a standalone HTML report, and a searchable list of evaluations.

In plain words
What is it for?
Use it to vet, score, compare, or stress-test product concepts and business opportunities.
Why use it?
It turns an informal idea into a documented decision aid with evidence, explicit assumptions, and conditions that could show the idea should be abandoned.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: mentions subagents; names the AskUserQuestion tool.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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

evaluate-startup 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 5d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/render.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 186 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Evaluate Startup

Turn a raw startup idea into an evidence-backed, scored evaluation with a durable, browsable artifact trail. The output is a decision aid, not a cheerleading document: honest scores, falsifiable assumptions, explicit kill criteria.

Tooling

All validate/render/index commands below use the bundled script:

uv run "${CLAUDE_PLUGIN_ROOT}/skills/evaluate-startup/scripts/render.py" <command> ...

Abbreviated as render.py in the phases. If ${CLAUDE_PLUGIN_ROOT} is not set in your environment, resolve the script path relative to this SKILL.md file.

Arguments

$ARGUMENTS may contain, in free-form order (all optional):

  • Idea description — anything from a one-liner to a full pitch. If absent, ask for it.
  • Output path — e.g. --out ./somewhere or "store results in X". Default: ./startup-ideas
  • Custom instructions — e.g. --instructions "..." or natural language like "focus on the EU market" or "add a competitor pricing matrix to the report". These tailor the interview, research angles, scoring weights, and report extras.

Interpret naturally; do not demand exact flag syntax.

Output layout

<output-root>/
├── index.html                     # searchable card index (auto-regenerated)
└── <idea-slug>/
    ├── analysis.json              # canonical latest evaluation
    ├── report.html                # rendered standalone report

        └── analysis-20260806T120000Z.json

Slug: lowercase, hyphenated, from the idea name (e.g. "Freight Invoice Audit Agent" → freight-invoice-audit-agent). If a directory with analysis.json already exists for this idea, this is a re-evaluation: move the old analysis.json into history/ before writing the new one. Never silently overwrite an evaluation.

The archive filename is analysis-<stamp>.json, where <stamp> is the old file's evaluated_at with - and : stripped (2026-08-06T12:00:00Z20260806T120000Z). Colons are illegal in Windows filenames, so never use the raw RFC 3339 value.

Files

What ships with it

6 files 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.
