@lmzhen/dsh-evolution-host

Host-plane self-evolution infrastructure bundle for DeepSeek Harness — the shrink path: the family's automation without the memory/skill model tools.

⚠️ Mutually exclusive install target. dsh-evolution-host is the infrastructure-only bundle: no memory/skill model tools (its single model-facing surface is the read-only maintenance_probe diagnostic), and it must be paired with the Evolution agent preset to expose memory/skill_manage. It shares its infrastructure rows with @lmzhen/dsh-evolution-preset; do not add both bundles to the same profile — pick host + the Evolution agent preset (layered), or the one-click preset bundle.

Compatibility. Validated platform line: DSH 0.2.0-rc.2; the @deepseek-ai/dsh-* dependency window is ^0.2.0-rc.1. A prerelease range does not cross lines — install this bundle on that line only (family-level statement and history: the repository README's Compatibility section).

Model surface

• Model-visible: the read-only maintenance_probe tool schema (from the evolution-maintenance/tools row) is its one model-visible artifact; everything else model-visible is owned by the packages that consume these services, and that schema is the only token this package adds.
• Prompt prefix / KV cache: independent of request-prefix construction — it does not alter the assembled prompt; the assembled TOOL list gains the read-only maintenance_probe row (the former "does not alter the tool list" claim was false); family-level rules: packages/README.md §"Model-visible prompt prefix and the KV cache".
• Mount it? yes — the infrastructure-only bundle; pair it with the Evolution agent preset; exclusive with evolution-all and the one-click preset.

Known limitations

• Host-only by design. It provides no memory/skill write tools: the read-only maintenance_probe diagnostic is the one exception; pair it with the Evolution agent preset to expose memory/skill_manage.

Runtime invariant: No companion is published. The platform auto-assembles nothing and the family mounts no <pkg>/invariant cordis row, so a companion here would never execute (v37 S2.1 / I-3).

Notes and history

• (V10-14 / H-02: the previous wording "pick host+preset" described the forbidden combination itself: "host + preset" IS the layered install, not an alternative to it.)
• 0.3.54 (route B): the DEFAULT full bundle is now @lmzhen/dsh-evolution-all (infra + model tools, profile-root). This package is the shrink path: the same automation minus the memory/skill model tools. all, host and the one-click preset are three ALTERNATIVE install targets: mounting two of them fails loud at startup (invariants: already registered).
• v20 correction: earlier revisions of this document claimed the bundle registers "NO model-facing tools" / "Zero direct token effect": that was inaccurate: the evolution-maintenance/tools row mounts the read-only maintenance_probe tool schema into every session. The claims below are now scoped to the prompt/assembly surface.
