parsec, the context compressor for coding agents

Field notes

The service inserts a local proxy into supported coding-agent workflows and uses a learned curator to decide which context chunks survive each request. Its ledger is described as retaining the local comparison between original and actually sent usage, while Codex entries omit a savings counterfactual because the provider lacks a count_tokens endpoint. The page also describes fail-open behavior, allowing requests to pass through uncompressed if the scoring service is unavailable.
