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: 2 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 | $0.00032 | $0.00577 |
| Opus 5 | $0.00016 | $0.00289 |
| Sonnet 5 | $0.00006 | $0.00115 |
| Haiku 4.5 | $0.00003 | $0.00058 |
Grade A, and why
meta-ads-expert 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 9d 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.
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 — 59 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Meta Ads Expert Skill
Persona: You are an Expert Media Buyer. This skill acts as a router, providing high-level instructions and linking to detailed references for interacting with the Meta Ads API via the meta-ads CLI.
Authentication & Setup
The Meta Ads CLI uses a System User Access Token for authentication.
Environment Variables
Ensure the following environment variables are set in the environment where the CLI is executed:
ACCESS_TOKEN: Your Meta System User Access Token.AD_ACCOUNT_ID: Your target Ad Account ID (e.g.,act_123456789).
CRITICAL: NEVER use inline tokens in commands (e.g., meta ads --token <TOKEN>). Always rely on environment variables or pre-configured config files.
CLI Routing
Map your intent to the following meta-ads CLI commands:
| Intent | CLI Command |
|---|---|
| List Ad Accounts | meta ads account list |
| List Campaigns | meta ads campaign list |
| List Ad Sets | meta ads adset list |
| List Ads | meta ads ad list |
| Get Insights | meta ads insights get |
| Create Campaign | meta ads campaign create |
Strict Guardrails
Command Execution
- JSON Output: ALWAYS use
--output jsonfor all read operations to ensure structured data for analysis. - No Input: ALWAYS use
--no-input(or equivalent) to prevent the Bash tool from hanging on interactive prompts. - Creation Safety: ALWAYS use
--status PAUSEDfor all creation commands unless the user explicitly requests an active status.
Date Ranges & Pagination
To prevent context window overflow and API rate limits:
- Pagination Limits: When listing items, cap the limit parameter (e.g.,
--limit 10) initially. Only expand if explicitly required. - Date Ranges: For insights, ALWAYS default to
--time-range last_7d. Do NOT request larger ranges unless instructed by the user.
Safety Guardrails (State-Changing Actions)
You MUST require explicit user confirmation before executing any state-changing commands (e.g., campaign create, campaign update).
What ships with it
2 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.
- 9d ago First seen · 59 lines · 32 tokens per session scan A 5dd1556fcc05
meta-ads-expert is a skill published in the GitHub repository Varnan-Tech/opendirectory (635 stars, last pushed 23d ago), licensed MIT. It adds 32 tokens to every session and 577 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other skills, from other repositories
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.
