Custom Build. Scoped per engagement.
A generic coding agent ships with someone else’s defaults. A Custom Harness is an agent harness built on Pi, an open, extensible agent, and shaped around your company: what it may touch, what it may spend, which models it may call, and how your team actually works.
Your engineers get one agent that already knows your conventions, and your security and finance teams get the controls they need to say yes to it.
BYOC (bring your own cloud): models run through your own AWS Bedrock, GCP Vertex or Azure accounts, or on local models, so your code and data stay where your policies say they should.
What we build
- Security: permissions per tool and per repo, sandboxed code execution, redaction of secrets and sensitive data, and an audit log of everything the agent does
- Budget: spend limits per person or team, cost visible per session, and alerts before anyone blows through a limit
- Models: which providers and models are allowed, through your own cloud accounts or local models, with routing (e.g. a cheaper model for simple tasks)
- Your way of working: your skills, conventions, internal MCP servers and workflows, built in rather than rediscovered by every engineer
- Distribution: a CLI your team installs in one step, optionally surfaced in Slack or the IDE
Tools / stack
- Pi: the open, extensible agent harness underneath
- AWS Bedrock / GCP Vertex / Azure / local models: model access under your accounts
- MCP servers: typed connections to your internal tools
- Sandboxed execution: isolated environments for the code the agent runs
- Your observability stack: audit and cost data where your team already looks
When it fits
Your engineers want coding agents, but “install whatever you like” isn’t acceptable to security, finance or legal. You want one harness the whole company can use, with the guardrails written in code instead of in a policy PDF.
