Add @deepseek-ai/dsh-agent-controller, composed in the base bundle, as the
entry through which a sender delivers a message from outside an Agent into
its inbox. deliver() runs the sender's content preparation in the Agent's
delivery order, asks the agent-controller/admission waterfall for a
decision, rechecks cancellation and registration, and appends the message
with followup() or steer(). dsh-agent and agent-loop are unchanged.
The Web session/prompt Remote delivers through it: the image model check,
upload receipt resolution, and attachment storage run as prepare, the
receipt binding runs as beforeInsert, and refusals map to
session/prompt-rejected. The Web client keeps its existing echo.
This replaces the Host half of deepseek-harness/deepseek-harness#6178,
whose admission stage lived in dsh-agent.
Add @deepseek-ai/dsh-agent-model. It provides ctx.agentModel
(resolveForNextStep, select, applyConfiguredRoute) and owns the
modelSelection projection, which the Agent registry no longer registers.
dsh-agent-loop now injects agentModel; the base and SDK-minimal bundles
and the Python SDK runtime include it.
The provider keeps the projection registered until consumers that are
still unloading finish their cleanup. The model-switch notice becomes an
opt-in per-Agent plugin at @deepseek-ai/dsh-agent-model/notice, and
agent/request now also rejects reasoning-effort changes after step
preparation.
Mount the provider in every composition that loads dsh-agent-loop, and
update consumers, the switch-notice snapshot driver, docs, and the
upgrade guide.
Read configured plugin market indexes on the Host, search them with fuzzy
multilingual matching, and install a chosen version from the Plugins page.
- dsh-plugin-market-index validates format-1 indexes and builds install
arguments; inline icons are capped at 32 KiB.
- The pluginMarket service fetches configured http(s) URLs, parses bodies in
a Worker Thread, caches documents, and pages filtered, ordered results with
installation status and engines.dsh compatibility.
- Discover is an opt-in experimental bundle; the Plugins page gains a
plugins.tab slot and confirmed installs.
- The plugin_market tool lists indexes, plugins, and versions for Creator mode.
- Plugin compatibility reads engines.dsh before DSH peer dependencies.
Reuse read_image and automatic compaction in the standalone profile without
adding SDK slash-command handling. Update profile guidance, upgrade steps,
and startup and recorded-session coverage.
