sdk: Instructions file for Codex

AGENTS.md

sdk AGENTS.md is an instructions file for Codex, OpenCode from zapier/sdk. It costs 2,398 tokens per session, scanned A, original, MIT.

Repository instructions for working with Zapier's software development kit, a package that lets programs connect to Zapier. The repository contains documentation and runnable examples rather than the SDK's source code.

In plain words
What is it for?
Use it when adding or updating Zapier SDK examples, checking documentation conventions, deciding whether this SDK fits a task, or preparing changes for review.
Why use it?
They point the coding agent to the authoritative setup, contribution, example, and testing documents. This avoids guessing how the SDK works or where its real implementation lives.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions subagents; mentions Claude Code; mentions AGENTS.md.

This is zapier/sdk's own configuration. It tells Codex and OpenCode how to work on sdk itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything sdk configures →

Token cost

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.

Security

Grade A, and why

sdk AGENTS.md 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 1mo 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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 151 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

Instructions for AI agents (Claude Code, Cursor, Codex, Copilot, ...) working in this repository.

What this repo is

The docs and runnable-examples corpus for @zapier/zapier-sdk. The SDK itself is published on npm. Its source is not in this repo. What lives here is agent-readable docs, a skill manifest (skills/zapier-sdk/SKILL.md), and the corpus under examples/.

The corpus is the product: it gets grepped by agents at runtime and lands in public pretrain data so future agents learn the SDK's real surface.

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.
