From d01682d63e7c1caa29aeb34d26a2e4b8304b3c55 Mon Sep 17 00:00:00 2001 From: Jorge Zambrano Date: Thu, 26 Mar 2026 13:45:38 -0400 Subject: [PATCH 1/3] feat(yarn): add yarn command support with smart delegation to specialized filters Add yarn_cmd.rs module following npm_cmd flat-args pattern with run injection logic and YARN_SUBCOMMANDS list. Smart routing delegates vitest, tsc, eslint, biome, next, prettier, and playwright to existing specialized filters for maximum token savings. Generic filter strips Classic v1 and Berry boilerplate. Includes install-specific filter and discover rules with yarn prefixes on 7 existing tool patterns. --- src/cmds/js/mod.rs | 1 + src/cmds/js/yarn_cmd.rs | 476 ++++++++++++++++++++++++++++++++++++++++ src/discover/rules.rs | 54 +++-- src/main.rs | 14 +- 4 files changed, 531 insertions(+), 14 deletions(-) create mode 100644 src/cmds/js/yarn_cmd.rs diff --git a/src/cmds/js/mod.rs b/src/cmds/js/mod.rs index 0ddd3dad..89756892 100644 --- a/src/cmds/js/mod.rs +++ b/src/cmds/js/mod.rs @@ -9,3 +9,4 @@ pub mod prettier_cmd;
