MANUAL TEMPLATE only for platform-specific writing rules. Most users should prefer the `platform-hat-deriver` skill which auto-generates platform hats from a populated SOUL. Use this template ONLY when the user wants raw manual control over every line of a platform hat (LinkedIn, Reddit, Slack, Discord, Twitter/X, Upwork, GitHub, etc.). Triggers on phrases like "give me the manual template", "I want to fill in platform rules myself", or "skip the deriver". Once copied and renamed, the user must replace every <<PLACEHOLDER>> with platform-specific rules. Layered on top of SOUL or a personal voice hat.
