What problem does it solve? Setting up a testing layer in an existing project often means overwriting conventions, guessing at tooling, or leaving docs disconnected from reality. This Skill installs the gsecure test-build layer into a project without destroying anything, adopting whatever test tooling, structure, and gates already exist and asking the developer only for what is genuinely missing. ## Core Features & Use Cases - Non-destructive installation: Copies agents, skills, references, and standards with merge/no-clobber semantics, appending to AGENTS.md under a marker instead of replacing it. - Evidence-based recon: Reads manifests, configs, and repo structure to detect the stack, existing test tooling, test structure, knowledge base, issue tracker, and static gates — every claim cited with a file path or command output. - Stack neutrality: Never suggests or pre-selects test runners, frameworks, or assertion libraries; missing tooling is decided by the developer and recorded verbatim. - Use Case: A team wants to add a structured unit-testing workflow to an existing repo. Run this once from the repo root; it merges in the test-build layer, confirms the real gate set, fills the coverage plan and test-mechanics docs from verified findings, and proves the setup with one smoke test. ## Quick Start Ask the AI to run the gsecure setup skill from the root of your project repository to install the test-build layer and configure it for your project.
