Govern every action an agent can take.
Control tools, skills, models, secrets, approvals, environments, knowledge access, and execution boundaries at runtime — not only in prompts.
Control cannot live only in the prompt.
Prompts can guide behavior, but they are not enforcement boundaries. When agents call tools, activate skills, query knowledge, access secrets, or create side effects, the runtime needs to understand what is allowed before the action happens.
Control the surfaces where agents create risk.
sypho treats runtime behavior as something that can be configured, enforced, and observed. Policies attach to deployments and apply during execution.
Every tool call is a runtime event.
Tool calls are where agent behavior becomes system behavior. sypho validates tool usage against schemas, permissions, environment rules, and approval policies before recording the result in the trace.

}Control reusable capabilities and context.
Agents should only activate the skills and access the knowledge they are allowed to use for a given deployment, environment, and customer. sypho makes skills and knowledge part of the runtime contract.
Skills
Skills package reusable instructions, resources, and executable workflows. sypho controls which skills are available to each deployment and records when they are activated.
Knowledge
Knowledge scopes define which vector collections and graph context an agent can access. sypho keeps context explicit, scoped, and observable.
Different environments need different rules.
A tool might be safe in staging but restricted in production. A skill might be available internally but not in a customer deployment. A model might be allowed for one environment and blocked in another. sypho keeps those boundaries explicit.
Why teams control agents through sypho.
Enforceable boundaries
Move critical controls out of prompts and into runtime policy.
Safer tool usage
Validate arguments, permissions, and approval requirements before actions execute.
Scoped context
Limit skills and knowledge access by deployment, environment, or customer.
Operational accountability
Record actions, decisions, approvals, and results in the run trace.
Environment-aware governance
Apply different controls for local, staging, production, customer cloud, and on-prem environments.
Control agents before they touch real systems.
