dsh-cost-estimate: Estimating Token Usage and Cost Before Answering

dsh-cost-estimate is a web plugin for DeepSeek Harness designed to provide upfront cost estimation and post-run billing reconciliation for large requests. It displays estimated input/output token ranges and costs before a response begins, then updates these values with actual data after the response completes. The plugin supports peak/off-peak pricing, threshold triggering, and cumulative cost tracking across multi-step tool calls. Its flexible configuration is well suited for developers who need fine-grained control over invocation costs.
