Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 5 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00045 | $0.04748 |
| Opus 5 | $0.00023 | $0.02374 |
| Sonnet 5 | $0.00009 | $0.00950 |
| Haiku 4.5 | $0.00005 | $0.00475 |
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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
Verify that `curl` and `python3` (or `python`) are available: How it starts
The opening of the file, as written. The whole thing — 541 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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.
What ships with it
7 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.
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.
- 13d ago First seen · 541 lines · 45 tokens per session scan A 785db2d56d42
domain-expired-opportunity-finder is a skill published in the GitHub repository Varnan-Tech/opendirectory (640 stars, last pushed 27d ago), licensed MIT. It adds 45 tokens to every session and 4,748 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

content-style
Writing Reddit-native content that sounds human, avoids AI tells, and delivers value through structure and specificity. Applies to workshop posts, definitive model guides, research megathreads, and community FYI/update posts.
coding-worktree-recovery
Use this skill when coding-agent work is interrupted, an agent exits without a clean commit, multiple controllers target the same checkout, or the checkout produces inconsistent file/Git behavior.
macos-storage-management
Safely reclaim local Mac storage without mistaking cloud placeholders for resident data, losing File Provider content, or flattening metadata onto an incompatible external filesystem.
hermes-mnemosyne
Mnemosyne is Hermes' primary local-first memory engine — SQLite with vector + FTS5 hybrid search, 19+ tools, auto-consolidation, and a standalone CLI. It's a pip-installed plugin (not a built-in toolset) discovered via $HERMESHOME/plugins/mnemosyne/.
skill-auditor
Audit any Hermes skill file and assign a quality grade based on clarity, completeness, tool guidance, and shareability. Returns specific fix suggestions ranked by impact.
marketplace-purchase-vetting
Use this when the user asks whether a local listing is a scam, "too good to be true," worth looking at, or a good deal. Also use this when he asks you to find options — search/discover candidates, then vet the best ones. The goal is not a generic buying guide; it is a practical risk read with clear next steps.
