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: 7 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 Privilege Escalation · line 89 Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.
- high Prompt Injection · line 213 Hidden instructions were detected in comments or invisible text. These could contain malicious directives. Manual review is recommended.Fix: Audit all comments and invisible characters. Remove any instructions that direct the agent to perform unauthorized actions. Use plain, reviewable content.
- high Supply Chain · line 281 Remote code is downloaded and executed. This bypasses code review and could introduce malicious code.Fix: Avoid downloading and executing remote scripts. Use trusted packages from PyPI/npm. If remote fetch is required, verify checksums and use HTTPS.
- medium Rogue Agent · line 34 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
- medium Data Exfiltration · line 92 Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.
- medium Data Exfiltration · line 123 Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.

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 | $0.00060 | $0.03655 |
| Opus 5 | $0.00030 | $0.01827 |
| Sonnet 5 | $0.00012 | $0.00731 |
| Haiku 4.5 | $0.00006 | $0.00365 |
Grade A, and why
marketing-campaign-builder 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 12d 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.

Marketing Campaign Builder
Overview
Most small businesses have a Mailchimp list they never use. They sent a few campaigns years ago, got busy, and stopped. This skill fixes that by making campaign creation fast and owner-gated:
- Owner texts a campaign idea in Telegram
- Agent drafts the email content + 2-3 subject line options
- Owner picks a subject line (or suggests their own)
- Agent creates an A/B test campaign in Mailchimp
- Agent sends a test email to the owner
- Owner approves → agent schedules the send at optimal time
The owner never writes HTML, never logs into Mailchimp, never touches a template editor. They just describe what they want and approve the draft.
When to Use
- "Send a summer special to all partners"
- "We haven't emailed the list in 3 months — draft a re-engagement campaign"
- "Send a seasonal reminder to all contacts in our service area"
- "Create a campaign about our new website estimator tool"
- "Send a holiday thank you to all customers"
Prerequisites
mailchimp-integrationskill installed + API key wired- MAILCHIMP_AUDIENCE_ID set in environment
- Owner available in Telegram to approve drafts
The Flow
Step 1: Owner Describes the Campaign
Owner sends a message in Telegram:
"Send a summer special to all partners — mention our partner pricing and that we do free estimates."
Agent extracts:
- Audience segment: "partners" (or "all contacts" if not specified)
- Topic: summer special
- Key points to include: partner pricing, free estimates
- Tone: matches the business (confident, professional, not salesy)
Step 2: Agent Drafts Content + Subject Lines
Agent generates:
- 2-3 subject line options (short, punchy, under 50 chars for mobile)
- Preview text (the snippet recipients see next to subject)
- Email body in HTML, matching the business brand voice
- Plain text version (for accessibility + spam filters)
Example output to owner in Telegram:
📧 Campaign Draft — Summer Partner Special
Subject line options:
A) "Summer Listings? Don't Let Odors Kill the Sale"
B) "Free Estimates for Your Summer Listings"
C) "Partner Special: Summer Service Discount"
Preview text: "[BUSINESS_NAME] — professional service for your
listings. Free estimates, partner pricing."
Body: [shows first few lines or summary]
Which subject line do you prefer? (A, B, or C — or type your own)
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.

marketing-campaign-builder is a skill published in the GitHub repository hewi333/Mom-n-Pop-Skills (120 stars, last pushed yesterday), licensed MIT. It adds 60 tokens to every session and 3,655 once invoked, about $0.0003 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.
