Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# builtin/prompt-preset
Builtin extension #7. On `before_agent_start` and `model_select`, picks a system prompt preset by **model family** (gpt-5.x through gpt-5.6, the gpt-6 family (astra/sol/luna share the gpt-6-astra preset), claude-fable-5, claude-fable-5-1, claude-opus-5-5, claude-opus-5, claude-sonnet-5-5, claude-haiku-5-5, claude-opus-4-{5,6,7,8}, glm-5.2, glm-5.3, deepseek-v4-{flash,flash-0731,pro}, deepseek-v4-1-flash, kimi-k2-{6,7,8}, kimi-k3, kimi-k3-1, grok-4.5, grok-4.6, grok-4.7 (its own tuned core since 2026-09-24, no longer a 4.6 copy), gemini-4-argon) and falls back to the senpi dynamic prompt when nothing matches. Renders the active preset name in the startup header. After 2026-04-30, presets are thin wrappers around `buildDynamicSystemPrompt()` carrying only model-specific tuning.

How to install
mdr add code-yeongyu/senpi/packages/coding-agent/src/core/extensions/builtin/prompt-preset/AGENTS.md@sha256:8045d816200c2db8The line at the top of this page pins the label git:20261102.d922725, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
