From 548a4f4f291b7e7724e2825528829f2e2a42077c Mon Sep 17 00:00:00 2001 From: David Sarno Date: Wed, 3 Sep 2025 15:36:21 -0700 Subject: [PATCH] feat: Add additive test suite and improve validation robustness MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add nl-unity-suite-full-additive.md: new additive test design that builds state progressively instead of requiring resets - Update claude-nl-suite.yml workflow to use additive test suite - Fix validation scoping bugs in ManageScript.cs: - Correct scoped validation scope calculation (was using newText.Length instead of originalLength) - Enable always-on final structural validation regardless of relaxed mode - Unify regex_replace and anchor_insert to use same smart matching logic in manage_script_edits.py - Additive tests demonstrate better real-world workflow testing and expose interaction bugs between operations - Self-healing capability: tools can recover from and fix broken file states 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- .../prompts/nl-unity-suite-full-additive.md | 240 ++++++++++++++++++ .github/workflows/claude-nl-suite.yml | 2 +- UnityMcpBridge/Editor/Tools/ManageScript.cs | 22 +- .../src/tools/manage_script_edits.py | 188 +++++++++----- 4 files changed, 380 insertions(+), 72 deletions(-) create mode 100644 .claude/prompts/nl-unity-suite-full-additive.md diff --git a/.claude/prompts/nl-unity-suite-full-additive.md b/.claude/prompts/nl-unity-suite-full-additive.md new file mode 100644 index 0000000..f4c65fe --- /dev/null +++ b/.claude/prompts/nl-unity-suite-full-additive.md @@ -0,0 +1,240 @@ +# Unity NL/T Editing Suite — Additive Test Design + +You are running inside CI for the `unity-mcp` repo.
