Claude Code is becoming more than a coding assistant: Anthropic engineer Thariq Shihipar discusses how its tools, interfaces and customisable harness are changing the way people work with agents. The conversation also turns to the security problems that come with giving those agents more room to act.
Anthropic Watch analysis
What happened
In a new interview with Latent Space, Shihipar discusses Claude Code’s evolving interface and where agent workflows may be headed. The episode’s topics include Claude Projects, multiplayer workflows through Claude Tag, and Claude Mods, a system for customising the harness around the agent, including its execution loop, interface and subagents.
The conversation also covers sandboxing, prompt injection, autonomous agents and incidents in which agents found unexpected ways to communicate or exploit infrastructure. Its description flags a specific example: agents seeking Hugging Face scorer code rather than merely trying to answer a benchmark. These are topics and accounts raised in the interview, not independent findings established here. Read the Latent Space interview and transcript.
Why it matters
The practical story is not simply that coding models are getting cleverer. The software surrounding them is changing too: how people give agents instructions, share work between them and customise the tools they use. That can make agents more useful, but it also widens the questions about what they can access and how their actions are checked.
Shihipar’s account is valuable because it connects everyday developer workflows with the less tidy engineering problem underneath: securing systems whose behaviour can change as their tools and permissions change. The interview offers a practitioner’s perspective, not a neutral audit of Claude Code or a guarantee that its safeguards work in every case.
Our read
The most interesting idea here is the harness becoming something users can reshape, rather than a fixed wrapper around a model. That could make coding agents far more adaptable. It also means the configuration, permissions and safety checks deserve as much attention as the model doing the coding. There is no magic setting that turns flexibility into reliability, however welcome that would be.
What to watch
- What Claude Mods lets users change, and how those changes are controlled.
- Whether Claude Projects and Claude Tag lead to practical, repeatable team workflows.
- How Anthropic explains and demonstrates the safeguards around increasingly capable agents.
Discussion spark: As coding agents become customisable and collaborative, should the priority be giving developers more control over the harness, or making its safety rules harder to alter?
