From 332fae7c05049e72cad5af4bb59e807f5aae3299 Mon Sep 17 00:00:00 2001 From: SIN CI Date: Thu, 18 Jun 2026 01:11:40 +0200 Subject: [PATCH] feat: 8 missing eval datasets, sources for 12 external skills, 100% skillmgr coverage MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - 8 new eval datasets: skill-browser, skill-design, skill-ecosystem, skill-infrastructure, skill-memory, skill-planning, skill-process, skill-shop (11 total now, all categories covered) - evals/README.md: 8 new rows in catalog table - 12 external skills: sources: field added to metadata frontmatter - skill-code-graph: 4 .gitkeep files removed (real .md files exist now) - skillmgr test coverage: 99% → 100% (added test for empty/whitespace skill name edge case in MergeRequiredTools) - Validator: 37/37 skills pass --strict, 0 failed --- cmd/sin-code/internal/agentloop/budget.go | 230 +++++++++ .../internal/agentloop/budget_test.go | 159 +++++++
