openChpok v0.1.0 — initial release
Local compaction proxy for AI coding agents. Sits between your agent and the API, trims verbose tool outputs (grep, ls, git log, find, git status) before they hit the LLM. Saves up to ~80% of tokens on noisy commands.
What works
- ✅ Claude Code via `ANTHROPIC_BASE_URL` (Anthropic Messages API)
- ✅ Codex CLI via `OPENAI_BASE_URL` (OpenAI Responses API)
- Subscription auth via `~/.codex/auth.json` picked up automatically
- ✅ Any client speaking Anthropic Messages or OpenAI Responses/Chat Completions
Compactors
| Compactor | Saves on fixture |
|---|---|
| `grep` / `rg` | ~80% |
| `ls -la` | ~78% |
| `git_log` | ~80% (caps at 20 commits, passes through on `--grep`/`--author`/`--since`) |
| `git_status` | 35–61% |
| `find` | ~15% |
Read/cat/Edit/Write/Glob — never compacted.
