## What it does

The skill uses `secret(...)` from `encore.dev/config`. It places a declaration at package scope, then reads the value by calling the returned function. The pattern fits Stripe keys, GitHub tokens, webhook signatures, database passwords, and other credentials. Secret names resolve to one shared value across the application.

Values can be assigned with `encore secret set` for `prod`, `dev`, `preview`, or `local`. For local work, a `.secrets.local.cue` file at the repository root can provide overrides; keep that file in `.gitignore` so its contents stay out of the repository.

Declaring `secret(...)` inside a function breaks the skill’s rule. The value must be read as `stripeKey()`, not as the variable itself.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add encoredev/skills --skill encore-secret -a claude-code
```
```bash
npx skills add encoredev/skills --skill secret -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/secret/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/secret/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add encoredev/skills --skill secret -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/secret/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add encoredev/skills --skill secret -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/secret/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install encoredev/skills secret
```

2. **Manually: put the files in place**
- File: `.github/skills/secret/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add encoredev/skills --skill secret -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/encoredev/skills --path encore/secret
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/secret/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add encoredev/skills --skill secret -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/encoredev/skills/tree/HEAD/encore/secret/SKILL.md

## When to use it
- declare an API key in Encore.ts
- read a credential inside a handler
- assign separate values by environment
- add local overrides with `.secrets.local.cue`
- pass a secret to a third-party SDK

## Example prompts
- Set up the Stripe credential in Encore.ts and show how the handler should read it.
- Configure `OpenAIKey` for `dev` with `encore secret set`, then pass it to the SDK.
- Create a local `GitHubAPIToken` override in `.secrets.local.cue` and show the required Git ignore entry.

when_to_use: >-
  User wants to load a private credential into the service without committing it to the repo — third-party API keys (Stripe, OpenAI, Twilio, SendGrid), database passwords, signing keys, OAuth client secrets, JWT signing keys, webhook signing secrets. Covers `secret()` declarations, calling the secret as a function to read its value, setting values via `encore secret set`, and `.secrets.local.cue` for local overrides.

# Encore Secrets

## Instructions

Secrets are encrypted, environment-scoped values managed by Encore. Declare them at package level by calling `secret(name)` and read them by calling the returned function.

```typescript
import { secret } from "encore.dev/config";

// Package-level declaration
const stripeKey = secret("StripeSecretKey");

// Read inside a handler
async function chargeCustomer() {
  const key = stripeKey();        // <-- function call returns the value
  const stripe = new Stripe(key);
  // ...
}
```

Secret names are globally unique across the application (the same name resolves to the same value everywhere).

## Setting values

```bash
# Set per environment type
encore secret set --type prod StripeSecretKey
encore secret set --type dev StripeSecretKey
encore secret set --type local StripeSecretKey
```

Environment types: `production` (alias `prod`), `development` (alias `dev`), `preview` (alias `pr`), `local`.

## Local overrides

For local development without going through `encore secret set`, create a `.secrets.local.cue` file at the repo root (gitignore it):

```cue
StripeSecretKey: "sk_test_local_..."
GitHubAPIToken:  "ghp_local_..."
```

## Common usage patterns

```typescript
// HTTP headers
const githubToken = secret("GitHubAPIToken");
const resp = await fetch("https://api.github.com/user", {
  headers: { Authorization: `token ${githubToken()}` },
});

// Webhook signature verification
const stripeWebhookSecret = secret("StripeWebhookSecret");
stripe.webhooks.constructEvent(rawBody, sig, stripeWebhookSecret());

// Connecting to a third-party SDK
const openaiKey = secret("OpenAIKey");
const openai = new OpenAI({ apiKey: openaiKey() });
```

## Guidelines

- Always declare `secret(...)` at package level, never inside functions.
- Read with a function call: `stripeKey()` not `stripeKey`.
- Set distinct values per environment via `encore secret set --type <env>`.
- Never commit secret values; use `.secrets.local.cue` for local overrides and gitignore it.
- For webhook signature secrets specifically, see also the `encore-webhook` skill.
