I-am-Yuike

By default, DeepSeek Harness injects its own identity opener, per-round runtime-context snapshots, and a skill-catalog message into every session, making it difficult for a persona preset to own the system prompt cleanly. I-am-Yuike solves exactly that: it packages the catgirl Yuike character into a two-file preset, uses complete: true together with includeRuntimeContext: false so the persona becomes the sole system-prompt section, and disables the skill-filesystem and tool-skill toolchain to eliminate catalog noise entirely.

Deployment is idempotent and safe. On first launch the plugin copies agent.cordis.yml and preset.yml into the .agent-presets/yuike/ directory; if the target already exists the step is skipped so an edited preset is never silently overwritten. After deployment the standard tool backbone stays intact: shell, filesystem read-write-search, background jobs, web fetch and search, plan mode with compaction, subagents, workflows, ralph, ask-user, todo, and present all remain available. The optional codex and claude-code subagent providers ship disabled and can be enabled by removing a single disabled: true line.

This plugin is designed for Harness users who want roleplay, creative fiction, or companion conversations where the character drives identity, language style, action brackets, emoji, and the affinity suffix from the very first token to the last. The entire personality is self-contained in the two template files, so cloning the repo on a new machine reproduces the experience with zero external dependencies.
