domain-expired-opportunity-finder

domain-expired-opportunity-finder is a skill for Claude Code from Varnan-Tech/opendirectory. It costs 45 tokens per session (4,748 once invoked), scanned A, original, MIT.

A screening workflow for expired internet domains—web addresses that are no longer registered—for a chosen subject area. It ranks candidates by topical fit, past activity, history cleanliness, and suitability for redirects, while showing risks.

In plain words
What is it for?
Use it to review expired-domain candidates, compare their histories, and create a cautious shortlist for human review.
Why use it?
It reduces the chance of choosing a domain with an unrelated or problematic history and makes uncertain recommendations easier to spot.

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

domain-expired-opportunity-finder scanned grade A with 1 finding 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 13d 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.

Expired Domain Opportunity Finder

Evaluate expired domain candidates for a specific niche. Score them on topical fit, historical activity level, history cleanliness, and redirect suitability. Output a conservative, explainable shortlist for human review.


Critical rule: Every recommendation must include BOTH a positive rationale (why_selected) AND a caution rationale (why_risky). Never output a bare score without explanation.

Conservative-by-default rule: When signals are incomplete or contradictory, lower the confidence level. Do not surface ambiguous candidates as strong opportunities. Missing data reduces confidence, never inflates it.

Anti-abuse rule: Never encourage unrelated redirects, PBN construction, or domain repurposing where the historical topic does not match the target niche. Read references/guardrails.md for the full anti-abuse policy.


Step 1: Setup Check

Check the environment before doing anything else.

Verify that curl and python3 (or python) are available:

curl --version > /dev/null 2>&1 && echo "curl: available" || echo "curl: MISSING"
python3 --version 2>/dev/null || python --version 2>/dev/null || echo "python: MISSING"

Check for an optional LLM API key for enhanced niche-relevance scoring:

echo "LLM_API_KEY: ${LLM_API_KEY:+set}"

If curl or python is missing: Stop. Tell the user: "This skill requires curl and Python 3.10+. Please install them and try again."

If LLM_API_KEY is not set: Continue. The skill will use rule-based scoring only (domain string matching, Wayback title analysis, keyword overlap). Note to the user: "Running in rule-based-only mode. Set LLM_API_KEY for enhanced niche-relevance scoring."

If LLM_API_KEY is set: The skill will use LLM-enhanced scoring for topical relevance analysis. This provides deeper contextual assessment of niche fit.

QA: State the scoring mode (llm-enhanced or rule-based-only) and confirm tools are available.

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.
