Compare agent skills before installing.

MANDATORY skill that activates whenever code is written to implement an OpenSpec change task. Triggers: openspec-plus-apply is active, /opsx-apply is running, the user is implementing tasks from an OpenSpec change, an implementer subagent dispatched by openspec-plus-apply is starting work, or the user invokes phrases like 'TDD for the change', 'implementing change tasks', or 'writing tests for spec scenarios'. Load before any production code is written for an OpenSpec change. Enforces strict RED-GREEN-REFACTOR per test (any test — acceptance, unit, edge case, helper). Iron Law: NO PRODUCTION CODE WITHOUT A FAILING TEST. Gherkin scenarios in spec.md are the canonical source for acceptance tests (every scenario MUST become at least one test); additional unit, edge-case, and helper tests are encouraged and follow the same per-test cycle.

Generate original one-ink or controlled two-ink editorial images from any theme, sentence, article idea, object, or reference photo. Always use this skill when the user asks for 单色海报、双色印刷、单色调视觉、蓝色/绿色孔版印刷、risograph、网点照片、复古或当代编辑排版、zine poster, monochrome editorial poster, duotone print, or asks to use the mono-color style. It uses an adaptive white, gray, or pale-beige substrate, no more than two printing inks, active negative space, terse human language, and strong serif/grotesk/mono typography without making retro styling the default or copying a source composition, wording, logo, or artwork. Produce both the final generation prompt and the generated raster image unless the user explicitly asks for prompt only.
