feat: implement Tier 1.1 Vault secret resolver
- Create vault-resolver.js: URI parser, auth chain (env → file → AppRole), in-memory caching - Add resolveConfigValueAsync() to pi-coding-agent for lazy vault URI resolution - Integrate vault credential resolution into auth-storage credential loading path - Add doctor check (checkVaultHealth) for vault setup validation at startup - Document vault setup, auth methods, examples, troubleshooting in preferences-reference.md - Add comprehensive test suite (18 tests) for vault URI parsing, auth, caching, fallback Auth Chain: 1. VAULT_TOKEN env var (simplest for local dev) 2. ~/.vault-token file (recommended for local dev) 3. VAULT_ROLE_ID + VAULT_SECRET_ID env vars (AppRole for CI/CD) Fail-open behavior: If vault unavailable, falls back to plaintext URIs to allow continued operation. URI Format: vault://secret/path/to/secret#fieldname Example: ANTHROPIC_API_KEY=vault://secret/anthropic/prod#api_key Tests: parseVaultUri, isVaultUri, resolveSecret, caching, edge cases all passing (18/18).

## Vault Secret Resolver (Tier 1.1)
|
||||
|
||||
### Overview
|
||||
|
||||
The Vault Secret Resolver allows you to store sensitive credentials (API keys, OAuth tokens) in HashiCorp Vault instead of plaintext in environment variables or config files.
|
||||
|
||||
**URI Format:** `vault://secret/path/to/secret#fieldname`
|
||||
|
||||
Example: `vault://secret/anthropic/prod#api_key` resolves the `api_key` field from the Vault secret at `secret/anthropic/prod`.
|
||||
|
||||
### Setup
|
||||
|
||||
#### 1. Install Vault
|
||||
|
||||
Download and install HashiCorp Vault from https://www.vaultproject.io/downloads.html.
|
||||
|
||||
Start a local dev server (for testing):
|
||||
```bash
|
||||
vault server -dev
|
||||
```
|
||||
|
||||
This outputs a root token and `VAULT_ADDR`.
|
||||
|
||||
#### 2. Create a Secret
|
||||
|
||||
```bash
|
||||
export VAULT_ADDR='http://127.0.0.1:8200'
|
||||
export VAULT_TOKEN='<root-token>'
|
||||
|
||||
vault kv put secret/anthropic/prod api_key='sk-ant-...'
|
||||
vault kv put secret/openai/prod api_key='sk-...'
|
||||
```
|
||||
|
||||
#### 3. Configure SF to Use Vault
|
||||
|
||||
Set your API key as a Vault URI in environment variables or `.env`:
|
||||
|
||||
```bash
|
||||
# Option A: Environment variable
|
||||
export ANTHROPIC_API_KEY='vault://secret/anthropic/prod#api_key'
|
||||
|
||||
# Option B: .env file
|
||||
OPENAI_API_KEY=vault://secret/openai/prod#api_key
|
||||
```
|
||||
|
||||
#### 4. Authenticate SF to Vault
|
||||
|
||||
Use one of these methods (tried in order):
|
||||
|
||||
**Method 1: Environment Variable (Simplest)**
|
||||
```bash
|
||||
export VAULT_TOKEN='<your-root-token>'
|
||||
sf execute-task "Hello"
|
||||
```
|
||||
|
||||
**Method 2: Token File (Recommended for Local Dev)**
|
||||
```bash
|
||||
# Save token to ~/.vault-token (readable only by you)
|
||||
vault token lookup # Confirm token is valid
|
||||
cat ~/.vault-token # Should show token
|
||||
|
||||
# Now SF will automatically use this token
|
||||
ANTHROPIC_API_KEY='vault://secret/anthropic/prod#api_key' sf execute-task "Hello"
|
||||
```
|
||||
|
||||
**Method 3: AppRole (Kubernetes / CI/CD)**
|
||||
```bash
|
||||
# Create AppRole on Vault (admin only)
|
||||
vault auth enable approle
|
||||
vault write auth/approle/role/sf-role token_ttl=1h policies="sf-policy"
|
||||
vault read auth/approle/role/sf-role/role-id
|
||||
vault generate-and-list-secret auth/approle/role/sf-role/secret-id
|
||||
|
||||
# Set environment variables
|
||||
export VAULT_ROLE_ID='<role-id>'
|
||||
export VAULT_SECRET_ID='<secret-id>'
|
||||
```
|
||||
|
||||
### Examples
|
||||
|
||||
#### Solo Developer
|
||||
|
||||
```bash
|
||||
# Start vault dev server
|
||||
vault server -dev
|
||||
|
||||
# Create a secret
|
||||
vault kv put secret/my-keys anthropic_key='sk-ant-...' openai_key='sk-...'
|
||||
|
||||
# Run SF with vault URIs
|
||||
export VAULT_TOKEN='<dev-root-token>'
|
||||
export ANTHROPIC_API_KEY='vault://secret/my-keys#anthropic_key'
|
||||
export OPENAI_API_KEY='vault://secret/my-keys#openai_key'
|
||||
sf execute-task "Write a poem"
|
||||
```
|
||||
|
||||
#### Team Deployment
|
||||
|
||||
Store secrets in a production Vault instance:
|
||||
|
||||
```yaml
|
||||
# Production Vault setup (admin responsibility)
|
||||
# 1. Create AppRole for SF
|
||||
# 2. Create secrets: secret/anthropic/prod, secret/openai/prod, etc.
|
||||
# 3. Assign read policy for SF role
|
||||
|
||||
# SF deployment (.env or deployment config)
|
||||
VAULT_ADDR=https://vault.company.com
|
||||
VAULT_ROLE_ID=<role-id>
|
||||
VAULT_SECRET_ID=<secret-id>
|
||||
ANTHROPIC_API_KEY=vault://secret/anthropic/prod#api_key
|
||||
OPENAI_API_KEY=vault://secret/openai/prod#api_key
|
||||
```
|
||||
|
||||
### Troubleshooting
|
||||
|
||||
Run `/sf doctor` to check Vault setup:
|
||||
|
||||
```bash
|
||||
/sf doctor
|
||||
```
|
||||
|
||||
**Common Issues:**
|
||||
|
||||
- **`vault_no_credentials`** — No VAULT_TOKEN or ~/.vault-token found. Set one using methods above.
|
||||
- **`vault_invalid_uri_format`** — URI doesn't match `vault://path#field`. Check format.
|
||||
- **`vault_unreachable`** — Can't connect to Vault server. Check VAULT_ADDR and firewall.
|
||||
- **Vault secret not found** — Path doesn't exist in Vault. Create it: `vault kv put secret/path field='value'`.
|
||||
|
||||
### Behavior
|
||||
|
||||
- **Lazy resolution:** Secrets are only fetched when an API key is actually used (not at startup).
|
||||
- **Caching:** Resolved secrets are cached in memory for 5 minutes to avoid repeated vault requests.
|
||||
- **Fail-open:** If Vault is unavailable, SF falls back to the plaintext URI (so you can continue working).
|
||||
- **No persistent cache:** Secrets are not cached to disk; Vault can revoke/update them at any time.
|
||||
|
||||
### Security Notes
|
||||
|
||||
- Never commit `.env` or config files with `vault://` URIs to version control.
|
||||
- Keep `VAULT_TOKEN` and `VAULT_SECRET_ID` in a secure location (use `~/.vault-token` or secret management).
|
||||
- Use AppRole in production; avoid root tokens.
|
||||
- Vault audit logs will record all secret access; review regularly.

/**
|
||||
* SF Vault Secret Resolver
|
||||
*
|
||||
* Purpose: Resolve secrets from HashiCorp Vault using URI syntax (vault://path#field).
|
||||
* Provides a secure alternative to storing plaintext API keys in config files.
|
||||
*
|
||||
* Consumer: pi-ai provider config layer for LLM model credentials.
|
||||
*
|
||||
* URI Format: vault://secret/path/to/secret#fieldname
|
||||
* Example: vault://secret/anthropic/prod#api_key
|
||||
*
|
||||
* Auth Chain:
|
||||
* 1. VAULT_ADDR and VAULT_TOKEN environment variables
|
||||
* 2. ~/.vault-token file (if VAULT_TOKEN not set)
|
||||
* 3. AppRole (Kubernetes-style) from VAULT_ROLE_ID and VAULT_SECRET_ID env vars
|
||||
* 4. Fails open: if vault unavailable, returns null (caller can fall back to plaintext)
|
||||
*
|
||||
* Caching: Results cached in memory to avoid repeated vault requests.
|
||||
* No persistent cache (vault secrets can change).
