What it does
E2a Integrate is an agent skill from tokencanopy/e2a. Use when adding e2a email capabilities to an application or codebase: outbound sending, inbound signed webhooks, REST polling, or SDK integration. Inspects the existing language and framework, uses official TypeScript/Python SDKs or idiomatic REST/OpenAPI, adds tests, and keeps credentials server-side.
Its SKILL.md is about 840 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `references/integration-modes.md`, `references/rest-openapi.md` and `references/sdk-recipes.md`).
It sits in Backend & APIs, covering Webhooks, OpenAPI specifications and Third-party API integration. It works with OpenAPI, Python and TypeScript. The repository describes itself as: Open-source email API for applications and AI agents. Managed hosting at e2a.dev, or self-host with Docker. The licence is Apache-2.0.

What it can do on your machine
Read from SKILL.md and the folder at commit 776fe2c. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
E2a Integrate loads about 840 tokens when it runs, and up to ~2.5k if it reads all its reference files. Until then it costs about 79 tokens; SKILL.md has 385 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- Use when adding e2a email capabilities to an application or codebase: outbound sending, inbound signed webhooks, REST polling, or SDK integration. Inspects the existing language and framework, uses official TypeScript/Python SDKs or idiomatic REST/OpenAPI, adds tests, and keeps credentials server-side.
Integrate e2a into an application
Determine the integration mode
Identify whether the request needs outbound sending, inbound signed webhooks, REST polling, or a combined flow. Ask only when the send/receive intent is materially ambiguous. Read integration-modes.md for the decision table.
Inspect the existing codebase
Find the language, framework, package manager, configuration conventions, server entry point, persistence layer, and test runner. Preserve the existing module, dependency, and test conventions. Do not create production credentials or put live addresses in fixtures.
Select the supported client surface
Use the official TypeScript/JavaScript or Python SDK when the application uses one of those languages; use REST and the OpenAPI contract for every other server language. Never invent an SDK or an unofficial wrapper. Read sdk-recipes.md or rest-openapi.md for the selected surface.
Build one application boundary
Add one application-owned e2a adapter boundary. Keep routes, domain logic, and workers dependent on that boundary rather than calling e2a throughout the application. Define server-only credential and webhook-secret configuration; never expose either to browser code, client bundles, logs, or test fixtures.
Make retried writes idempotent with a stable key derived from the application's
logical operation. Treat accepted, scheduled, and pending_review as
durable acceptance states; a send in any of these states must not be resent or
retried. Durable acceptance is not terminal delivery. Observe eventual delivery
through the application's requested webhook, event-log, or polling flow, and
handle failed outcomes through its existing error and job conventions.

Secure inbound webhooks
For a webhook integration, retain the raw request bytes and perform signature verification before JSON parsing or dispatch. Deduplicate at-least-once events by event ID in durable application state when it is available, then make the handler's side effects idempotent. Follow webhooks-and-tests.md for framework-safe verification and recovery details.
Test and verify
Add synthetic unit and contract tests using .test addresses and fixture
payloads. Cover the adapter, configuration failures, signature rejection before
parsing, duplicate-event behavior, and requested send/poll behavior. Run the
repository's focused and relevant full test commands.
Keep an explicitly approved live smoke test separate from synthetic tests. Do not create credentials, send mail, or run that smoke test without approval and an explicitly selected synthetic recipient.
Completion report
State the integration mode, selected client surface, application-owned boundary, server-only configuration contract, webhook verification and deduplication status where relevant, tests run, and any deliberately unrun approved-live smoke test.
