Description

LeanCTX is a hybrid context optimizer designed to reduce token consumption in AI-assisted software engineering workflows. It acts as a cognitive filter between AI tools and Large Language Models (LLMs), stripping noise like comments and whitespace to lower costs and maximize context efficiency.

Features:

AST-Aware Compression: Uses Tree-sitter to parse 14 languages, preserving critical types and logic while reducing token counts by up to 90%.
MCP Server Integration: Provides 24 tools that replace standard file reads with compressed alternatives for any MCP-enabled AI client.
Automated Shell Hook: Intercepts and compresses output from over 90 common command patterns (git, npm, cargo, docker, kubectl, etc.).
Privacy and Performance: Single Rust binary with zero dependencies and no cloud requirements.

ai/lean-ctx: update to 3.11.4 (#1870)

## Summary - Update lean-ctx 3.6.9 → 3.11.4; regenerate `CARGO_CRATES` / distinfo - Correct `LICENSE` from `mit` to `Apache-2.0` (upstream `LICENSE` and `Cargo.toml` are Apache-2.0, already true at 3.6.9) - Add FreeBSD's `ort` crate patch so `libonnxruntime.so` is the default on `target_os = "freebsd"` (build otherwise fails with E0004 non-exhaustive match) - Set `NO_TEST`: upstream `proxy_autostart.rs` tests are gated on `cfg(unix)` but use helpers only compiled on macOS/Linux, so `cargo test` fails to compile FreeBSD's `patch-src_core_engine__artifact_unix.rs` was intentionally not imported: it isn't needed for 3.11.4 to build, and it hard-codes syscall 602 (renameat2), which exists only on FreeBSD 15+. ## Testing (amd64, master) …

ai: add new category and move AI/ML ports from misc

Create the ai category (Artificial intelligence and machine learning) and relocate 42 AI/ML ports from misc into it. - Register ai in Mk/bsd.mport.mk VALID_CATEGORIES and the top-level Makefile - Add ai/Makefile; drop the moved entries from misc/Makefile (also removes the stale linux-claude SUBDIR left over from the claude-code rename) - git mv 42 ports and set their primary CATEGORIES to ai - Rewrite misc/<port> dependency origins to ai/<port> in external dependents (devel/py-beartype, math/py-faiss, multimedia/py-torchcodec, textproc/py-tokenizers) and among the moved ports themselves - Record the origin migrations in MOVED Ports moved: chatgpt-shell-cli, claude-code, claude-code-legacy, clawhub, codex, gemini-cli, github-copilot-cli, grok-cli, lean-ctx, llama-cpp, ollama, …
