Read it at the original source: ## Questions this post answers ### Why do AI coding agents burn through so many tokens on large codebases? A large part of token burn comes from agents exploring a codebase broadly in response to vague instructions, pulling many files into context that never end up informing the actual change. Because a long-running session re-sends its full history on every new request, a file read on turn three is still being billed on turn forty, compounding the cost. _daily.dev readers optimizing AI agent workflows can dig into strategies like scoped prompting and fresh sessions._ ### Why do mocks make AI coding agents burn more tokens instead of fewer? Mocks increase token burn because they hand an agent confidently wrong information instead of missing information. A mock is a snapshot of a dependency's shape at creation time that drifts out of sync as the real system changes, so when an agent writes correct code against the current reality, it fails against the stale mock, and the agent burns turns 'fixing' code that was never broken. _developers deciding whether to trust mocks or live dependencies can track this trade-off through daily.dev._ ### How does mirrord reduce token costs for AI coding agents working on Kubernetes services? mirrord connects an AI agent's locally running code to a real Kubernetes cluster without deploying it, letting the agent read the actual shape of a dependency, such as what's on a queue or what a service currently returns, before writing code. This collapses the typical guess-then-fail-then-regenerate cycle into one or two passes because the first draft is already written against verified reality instead of an assumption. _teams weighing tools for connecting AI agents to real Kubernetes clusters can follow developments like this on daily.dev._ ## Similar posts on daily.dev - [How To Prevent Token Burn Using mirrord With E2E Tests](https://daily.dev/posts/how-to-prevent-token-burn-using-mirrord-with-e2e-tests-9rav0oih4) · MetalBear · 1 upvotes · 0 comments - [Running AI Agent Pools Against Your Live Kubernetes Cluster, with mirrord](https://daily.dev/posts/running-ai-agent-pools-against-your-live-kubernetes-cluster-with-mirrord-1rgeqa8yd) · MetalBear · 0 upvotes · 0 comments - [Testing Is the New Bottleneck for AI-Driven Software Development](https://daily.dev/posts/testing-is-the-new-bottleneck-for-ai-driven-software-development-azhhistin) · MetalBear · 0 upvotes · 0 comments - [What Happens After AI Writes the Code](https://daily.dev/posts/what-happens-after-ai-writes-the-code-nwd4gpoui) · MetalBear · 19 upvotes · 1 comments --- Tags: [#kubernetes](https://daily.dev/tags/kubernetes), [#ai-agents](https://daily.dev/tags/ai-agents), [#claude-code](https://daily.dev/tags/claude-code) [View this post on daily.dev](https://daily.dev/posts/how-to-reduce-token-costs-of-ai-coding-agents-iu96kejpk)
