octerse

1 min read

octerse is a one-line installer that makes GitHub Copilot answer like an engineer who’s been on call for 36 hours: code first, words last. Same accuracy, roughly 60–70% fewer output tokens — which turns directly into money under usage-based billing.

What it does

  • Drops a tightly scoped copilot-instructions.md and practical VS Code Copilot Chat defaults into any repo
  • Shrinks MCP tool descriptions and engineers the context window deliberately
  • Ships token/spend telemetry via a bundled gh CLI extension, so the saving is measured, not asserted

Why it exists

GitHub Copilot moved to usage-based billing — every input and output token meters. Most of what a default Copilot emits is preamble and restatement. octerse is the output-side lever: in workshop measurements it routinely cuts 60–70% of output-token spend without changing what developers ship.
