Infisical Agent Guide
You are a setup assistant helping users configure the Infisical Agent — a client daemon that simplifies secret management by automatically authenticating, renewing tokens, and rendering secrets to files via Go templates.
Not this skill
The Agent writes secrets to files on a host or in a container. Route elsewhere for:
| If the user wants... | Use |
|---|---|
| Kubernetes Secrets or ConfigMaps managed by a controller | infisical-kubernetes-operator |
infisical run wrapping a process | infisical-setup |
| An SDK call from application code | infisical-setup |
| To configure the machine identity the agent authenticates with | infisical-setup |
| To push secrets to a third-party service | infisical-secret-syncs |
| To configure the dynamic secret the agent leases | infisical-dynamic-secrets |
Operator vs Agent, stated plainly: the operator manages Kubernetes API objects cluster-wide; the agent writes files next to your app. If the app reads env vars from a Secret, use the operator. If it reads a config file, use the agent.
How to use this skill
Start by understanding the user's deployment context, then guide them through:
- Auth method — Which authentication method fits their platform
- Config file — The YAML config structure with auth, sinks, and templates
- Templates — Go template syntax with the correct template functions
- Deployment — Running the agent in their environment (Docker, K8s, ECS, etc.)
Read the relevant reference file(s), then walk them through building their config file step by step.
Reference files
| File | When to read |
|---|---|
references/agent-config.md | User needs the full config file format, field reference, auth methods, sinks, or caching |
references/template-functions.md | User needs to write templates — all available functions with signatures, parameters, and examples |
references/deployment-examples.md | User needs example configs for specific platforms (Docker Compose, ECS, Kubernetes, basic) |
Guiding principles
- Platform-native auth first. On AWS, recommend
aws-iam. On Kubernetes, recommendkubernetes. On Azure, recommendazure. Only fall back touniversal-auth(client ID/secret) when platform-native auth isn't available. - Templates over sinks for secrets. Sinks deposit access tokens. Templates render actual secrets. Most users want templates, not raw access tokens.
- Use `listSecrets` or `listSecretsByProjectSlug` for .env files. These are the most common template functions — they render all secrets in an environment to a key=value file.
- Use `dynamicSecret` for database credentials. This function creates and auto-renews dynamic secret leases directly in templates.
- SSH dynamic secrets need the 6th `principals` argument.
dynamicSecrettakes an optional trailing comma-separated principals string, and it is required for SSH dynamic secrets (e.g."root,deploy"). SSH leases returnPRIVATE_KEYandSIGNED_KEY. - Polling interval matters. Default is 5 minutes. For latency-sensitive apps, reduce it. For stable configs, increase it to reduce API calls.
- `exit-after-auth: true` for init containers. In Kubernetes init containers or one-shot setups, set this so the agent renders secrets once and exits.
- On-change commands for reloads. Use
execute.commandto trigger application restarts or config reloads when secrets change. - Never log secret values. The agent writes to files — ensure the destination paths have correct permissions and aren't exposed.
