What is CTX?

CTX is a Rust-built local runtime for coding agents like OpenCode, turning repo code, logs, diffs, and AGENTS.md rules into a queryable graph memory. It delivers compact, task-specific context slices via CLI like `ctx pack "fix auth test"` or MCP tools over stdio/HTTP JSON-RPC, slashing prompt noise from giant markdown dumps or full file trees. Think ctx context engineering: index once, retrieve surgically.

Why is it gaining traction?

Proven token cuts—demo benchmarks hit 57% reduction with full query coverage and perfect answer quality vs. raw markdown. OpenCode-first: auto-generates `/ctx-*` commands for doctor checks, memory search, log pruning, and packs, keeping agents focused without workflow breaks. Local SQLite graph, semantic ranking, and privacy defaults (no net calls, sensitive file blocks) hook devs tired of bloated contexts.

Who should use this?

OpenCode users debugging flaky tests, pruning git diffs/logs, or migrating AGENTS.md to structured memory. Backend devs on Rust/Python/JS repos needing ctx = context todo() retrieval for root-cause fixes, or teams benchmarking ctx beta 800-style savings before scaling AI prompts.

Verdict

Promising for niche OpenCode workflows despite 18 stars and 1.0% credibility score—strong docs, reproducible benchmarks, and Homebrew formula offset early maturity. Cargo install, run `ctx opencode install`, and test on your repo; skip if not agent-heavy.
