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: 3 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 →
- high Tool Misuse · line 668 Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.

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 | $0.00172 | $0.07118 |
| Opus 5 | $0.00086 | $0.03559 |
| Sonnet 5 | $0.00034 | $0.01424 |
| Haiku 4.5 | $0.00017 | $0.00712 |
Grade A, and why
npm-downloads-to-leads 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.

The opening of the file, as written. The whole thing — 671 lines — stays where its author put it; the contents beside it link to each section on GitHub.
npm Downloads to Leads
Take a list of npm packages. Fetch 12 weeks of download data. Compute breakout velocity. Enrich maintainer profiles. Output a ranked lead brief per breakout package with contact signals and an outreach message.
Critical rule: Every package download figure in the output must come from the npm API response. Every maintainer GitHub handle or Twitter username must come from the GitHub API response -- not guessed from the npm username. If the GitHub API did not return a twitter_username field, write "not found on GitHub" -- do not invent one.
Common Mistakes
| The agent will want to... | Why that's wrong |
|---|---|
| Fetch GitHub profiles for every package in the list | Rate limit is 60 req/hr without a token. Enriching steady or declining packages wastes the budget before reaching breakout ones. Only fetch profiles for breakout and watching packages. |
| Rank packages by raw weekly downloads | Raw downloads favor React and lodash, which are not leads. A package going from 1K to 8K/week is more actionable than React at 50M/week. Velocity score is the signal. |
| Skip URL-encoding for scoped packages | @org/pkg without encoding causes a 404 from the npm API. Encode @ as %40 and / as %2F for every scoped package name. |
| Stop the skill when the GitHub rate limit is hit | Degrade gracefully. Present the velocity leaderboard from npm data, skip remaining GitHub enrichments, and add a flag to data_quality_flags. Do not abort. |
| Write outreach messages without naming the specific package | Generic "I saw your project" messages go unanswered. Every outreach message must name the package, its growth numbers, and a specific connection to the context the user provided. |
| Include packages below 500 weekly downloads as leads | Below 500/week is noise. The maintainer has no meaningful audience yet. Flag as "too early" but do not present as a lead. |
Step 1: Setup Check
echo "GITHUB_TOKEN: ${GITHUB_TOKEN:-not set, unauthenticated rate limit applies (60 req/hr -- enough for ~10 packages)}"
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.
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.

npm-downloads-to-leads is a skill published in the GitHub repository Varnan-Tech/opendirectory (640 stars, last pushed 27d ago), licensed MIT. It adds 172 tokens to every session and 7,118 once invoked, about $0.0009 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.
