`ui-question`'s node half called `ctx.tools.register` on the host context.
`ScopedLayers.merge()` combines the global layer with the agent's exact-scope
layer, and an unscoped registration lands in the global one — so the tool
reached every agent no matter which preset composed it. `core-web`, sold as a
two-tool benchmark surface, really presented three.
Rendering a question is a host UI capability; having the tool is an agent
capability, and only a preset decides that. The node half is now empty and the
`tool-ask-user` row moved into the preset that wants it. The TUI keeps its own
row, having no presets.
The composition tests now assert the global tool layer is EMPTY, which is the
invariant that would have caught this: any tool outside a preset reaches every
agent. The browser lane's composition, seeded-history, and hermetic-skill
assertions address their registries through a composed agent for the same
reason — those services are per session now, and the host cannot resolve an
`isolate` realm by name.
The bundle split emptied `apps/cli`'s plugin dependencies, and the flat module
fallback links only that manifest's closure — so a preset row naming
`@deepseek-ai/dsh-persona` resolved to nothing and every preset mount failed,
leaving each session with an agent that had no tools, persona, or token meter.
Which packages the shipped presets compose is not implied by any bundle: the
presets live beside this manifest, so this is where their closure is declared.
The hermetic skill test now addresses the registry through the composed agent,
the only shape that can see a preset's `isolate` realm.
The Windows layer previously kept the approval service with policy 'never',
which made the approval plugin inject 'Approval prompts are disabled in
this session: actions that require approval are rejected automatically'
into the model context. On Windows nothing asks for approval — the
escalation surfaces (sandbox_permissions) do not exist — so the sentence
described a rejection surface that is not there. The layer now disables
the approval row too: the service is absent, the model is never told
approval exists, and the danger-full-access degradation is complete.
base.spec.ts pins approval among the Windows disables; the Agent Note and
bundle README record the absent service.
The shipped surface stopped being two yml files: `base.cordis.yml` and
`web.cordis.yml` are bundle patch layers now, applied over an empty preset
root. This test still opened the old paths, so it failed before asserting
anything. It composes the same two layers the profile boot composes, over the
same empty root, and heals the flat module fallback the way the boot does —
the root lives outside this workspace, so bare plugin names have no other way
to resolve.
The web bundle's runtime row is disabled beside the webserver: it injects
`httpServer`, so a disabled port leaves it pending forever. It owns dist
serving and the URL prompt line, neither of which decides an agent's
capabilities.
`apps/cli` declares the packages the shipped agent presets name again. The
bundle split emptied its plugin dependencies, and the flat fallback links only
the app's dependency closure — so a preset row naming `dsh-persona` resolved
to nothing, and every preset mount failed. Which packages the shipped
presets compose is not implied by any bundle: the presets live beside this
app's config, so this app is what has to declare them.
Code Mode was a deployment-wide field on the host `tools` row: a
deployment ran every session that way or none. The obvious product
shape — 代码模式 beside 标准/极简/创造 in the preset picker — had
nothing to hang on.
The registry itself cannot move into a preset; the agent loop's
scheduler, the api-proxy's presenters, and every tool plugin are its
consumers. So split the registry from its projection: `presentAs(mode)`
writes one cell on the calling agent's scope layer, exactly as
`restrict()` does, and the three reads that decided presentation take
that scope's mode instead of the service's. The config `mode` becomes
the default agents shadow rather than a process-wide fact.
Two consequences are load-bearing. `run_code` now enters a view only
for scopes whose own mode presents it — a native agent must not find it
dispatchable because another agent in the process does — and the
reserved name holds whatever the configured mode, since any agent may
select a code mode later.
`dsh-agent-tool-mode` is the row a preset carries to declare this. A
code mode waits for the host's `codeRuntime` rather than assuming it,
so a runtime-less deployment fails the preset at mount, naming the
row, instead of at the session's first request.
The shipped `code` preset is `standard` plus that row, ordered second.
`ui-question`'s node half called `ctx.tools.register` on the host context.
`ScopedLayers.merge()` combines the global layer with the agent's exact-scope
layer, and an unscoped registration lands in the global one — so the tool
reached every agent no matter which preset composed it. `core-web`, sold as
a two-tool benchmark surface, really presented three, and a locally authored
`bash-only` preset presented two.
Rendering a question is a host UI capability; having the tool is an agent
capability, and only a preset decides that. The node half is now empty and
the `tool-ask-user` row moved into the presets that want it. The TUI keeps
its own row, having no presets.
The web composition test now asserts the global tool layer is EMPTY, which
is the invariant that would have caught this: any tool outside a preset
reaches every agent.
A composition is a file, but "edit it on the filesystem" is not a browser
affordance. The roster gains `read`/`write`/`remove` beside `select`, and
the browser gains a settings section over them: the presets as rows, one
composition open in a YAML editor at a time, and per-row default, duplicate,
and delete.
All four authoring methods are loopback-pinned. A composition names the
plugins a session runs, so reading one is reconnaissance, writing one is
arbitrary capability, and selecting one can move a session onto a preset
that edits the live runtime. `agentPreset.list` deliberately stays ordinary
and now reports `authorable`, so a surface knows whether creating is
possible at all rather than offering a button whose save always fails.
Authoring starts by duplicating: a shipped preset opens read-only because
the deployment's copy is what a broken local one is compared against. Ids
are contained before they become directory names, and the text is parsed
with the loader's own schema, so a save cannot leave a file no session
could load.
Fixes a defect the real-composition test found: a preset written under the
user's home could never mount, because the loader resolves a row against the
composition's own directory and Node's `node_modules` walk from there never
reaches the installed harness. The mount now records the host base and sends
bare specifiers there, leaving relative paths resolving from the preset.
Also closes the coverage the earlier surfaces in this stack shipped without —
the General row, the composer seat, and the plugin halves now have tests.
