| Signal | openspec-plus-apply MANDATORY skill that activates whenever the OpenSpec apply phase begins. Triggers: /opsx-apply runs, the openspec-apply-change vanilla skill is referenced or active, `openspec instructions apply` is invoked, or the user asks to implement, apply, execute, or build out an OpenSpec change ('implement the change', 'apply tasks', 'execute change', 'build out the change'). Takes over only vanilla step 6 (implementation loop) and emulates step 7 output (final status). | mono-color 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. |

| Warnings | The skill depends on the external `openspec-plus-tdd` skill and a vanilla `/opsx-apply` environment, but the submission does not document how to verify or install those dependencies. · No OpenAgentSkill engagement data yet | No OpenAgentSkill engagement data yet |
