Agent Skills
Install the Keplars skill to give AI coding agents accurate knowledge of the Keplars API so they generate working integration code on the first try.
AI coding agents (Claude Code, Cursor, Windsurf, Codex) sometimes hallucinate API endpoint paths or wrong field names. The Keplars skill fixes that by giving agents a concise, structured reference of the exact endpoints, request shapes, and patterns they need.
Install
npx skills add KeplarsHQ/keplars-skillsThe CLI installs the skill into your agent's config directory automatically:
| Agent | Config location |
|---|---|
| Claude Code | .claude/CLAUDE.md |
| Cursor | .cursor/rules/keplars.mdc |
| Windsurf | .windsurf/rules/keplars.md |
| Codex | .codex/instructions.md |
What the skill teaches
Once installed, your agent knows:
- Priority queue endpoint selection - which of the 5 endpoints to use and when (
/instant,/high,/async,/bulk,/schedule) - Request body shapes - all fields, types, required vs optional
- Template emails -
template_id+params, Handlebars syntax, what not to include - Scheduling - date format, timezone (IANA), constraints
- Webhooks - full event list, HMAC-SHA256 signature verification
- Common mistakes - the 4 things agents get wrong without the skill
Usage
After installing, ask your agent naturally:
"Add email sending to my signup flow with Keplars"
"Send a password reset email using the Keplars API"
"Set up a Keplars webhook to track email opens and bounces"
The agent reads the skill and generates working code using the correct endpoints and field names.
Migrating from another provider?
The skill also includes migration guides:
Ask your agent: "I'm migrating from Resend to Keplars, update my email integration" and it will handle the field renames and endpoint changes automatically.
