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 | $0.00205 | $0.01873 |
| Opus 5.5 | $0.00082 | $0.00749 |
| Sonnet 5.5 | $0.00041 | $0.00375 |
| Haiku 4.5 | $0.00020 | $0.00187 |
Grade A, and why
buttondown-cli 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 today.
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 — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.
<quick_start>
The buttondown CLI follows this pattern:
buttondown [--profile NAME] <command-group> <action> [arguments] [options]
| Task | Command |
|---|---|
| Check authentication | buttondown auth status |
| List profiles | buttondown auth profiles list --table |
| Create or switch profiles | buttondown auth profiles create PROFILE |
| Use a specific newsletter | buttondown --profile atalearning emails list |
| List subscribers | buttondown subscribers list --limit 25 |
| Get a subscriber | buttondown subscribers get SUBSCRIBER_ID_OR_EMAIL |
| Create a draft email | buttondown emails create --subject "Subject" --body-file ./draft.md |
| List draft emails | buttondown emails list --filter "status:eq:draft" |
| Render an email as HTML | buttondown --profile atalearning emails render EMAIL_ID --output /tmp/email.html |
| Preview an email in browser | buttondown --profile atalearning emails render EMAIL_ID --open |
| List RSS feeds | buttondown --profile atalearning feeds list --table |
| Inspect an RSS feed | buttondown --profile atalearning feeds get FEED_ID |
| List automations | buttondown --profile atalearning automations list --table |
| Inspect an automation | buttondown --profile atalearning automations get AUTOMATION_ID |
| List tags | buttondown tags list --table |
| Get tag analytics | buttondown tags analytics TAG_ID |

Context: Applies when maintaining or extending buttondown subscribers list, buttondown emails list, or buttondown tags list.
Key Facts: The Buttondown OpenAPI spec exposes page_size for /tags, but not for /subscribers or /emails. Keep page_size scoped to tags. Subscribers and emails should use the documented paginated response next link and stop after the requested --limit.
Gotchas: Do not add undocumented limit or page_size query parameters to subscribers or emails unless the OpenAPI spec changes.
What ships with it
1 file 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.
