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.

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 | $0.00011 | $0.01268 |
| Opus 5 | $0.00005 | $0.00634 |
| Sonnet 5 | $0.00002 | $0.00254 |
| Haiku 4.5 | $0.00001 | $0.00127 |
Grade A, and why
post-medium 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 11d 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 — 133 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Medium Posting Skill
Platform Overview
Medium is a popular blogging platform with strong Google SEO (domain authority 96). Articles can reach millions through Medium's internal recommendation engine and external search traffic. 100M+ monthly readers. Great for thought leadership and reaching audiences beyond the developer community.
IMPORTANT: Vietnam Access Limitation
Medium is BLOCKED in Vietnam. The browser agent will NOT be able to access medium.com without a VPN.
Workarounds
- VPN Required: User must enable VPN before the agent attempts to post
- Pre-check: Before posting, navigate to
https://medium.comand verify it loads - If blocked: Save the article content to
posts/drafts/medium_post.mdand instruct the user to:- Enable VPN
- Open medium.com manually
- Copy-paste the content
- Alternative: The agent can retry after the user confirms VPN is active
Automation Flow with VPN
- Ask user: "Medium is blocked in Vietnam. Is your VPN active?"
- If yes: proceed with browser automation
- If no: save draft and inform user to enable VPN first
Posting Method: MANUAL PASTE (Recommended)
Due to VPN requirement and potential bot detection, Medium uses Manual Paste mode. The agent generates content and saves it to
posts/drafts/medium_post.md.
Platform Constraints
- Length: No character limit — 5-10 minute reads perform best (1,500-3,000 words)
- Format: Rich text editor, supports code blocks, images, embeds
- Tags: Up to 5 tags per story
- Paywall: Can publish behind Medium's paywall (Partner Program) for earnings
- Publications: Can submit to publications for 10x-100x wider reach
- Canonical URL: Set canonical URL when cross-posting from your blog
Content Format
# {Title -- compelling and keyword-rich}
{Subtitle / deck -- 1 sentence summary}
{Opening hook: personal story, surprising stat, or bold claim}

{Content explaining the background}

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.
