The Web search switch selects the DeepSeek Search and Fetch APIs together,
and both reuse the DeepSeek chat key by default. Neither provider answered
readiness, so a step without a usable key was offered web_search and
web_fetch whose every call failed, and a conversation on another provider's
model or behind a gateway sent the chat key to DeepSeek.
dsh-web gives WebFetchProvider an optional ready(llmProvider) and adds
ctx.web.fetchReady(), which asks only the provider fetch() selects, as
searchReady() does for search. tool-web registers web_fetch with a step
activation condition on fetchReady(), so a step that cannot fetch leaves the
tool out of declarations, guidance, and PTC bindings and refuses a call to
it as UNKNOWN_TOOL; without web_fetch the search guidance uses its
search-only text. The shipped HTTP fetch provider has no ready() and stays
admitted.
web-deepseek-api applies the API-key rules of Messages search to both APIs:
without a literal apiKey, an apiKeyEnv other than DEEPSEEK_API_KEY, or a
baseURL other than the default, the chat key goes only to the DeepSeek
routes and only to an API base on the official chat route's origin. The
refusal sits in the key's only resolver, and both providers' ready()
answers presence in the order an operation resolves credentials. The
transport repeats these checks so the package still does not depend on
dsh-web-search-deepseek.
Master's step-scoped conditional activation resolves each tool's condition
before a model step assembles, and both the declarations and dispatch read
that admitted set. Prompt assembly no longer carries tool declarations, so
tool-web's system-prompt/assemble listener could not remove web_search any
more, and removing a declaration there never stopped a repeated call from
running.
tool-web now registers web_search with a when condition that asks
ctx.web.searchReady() about the route of the step's model selection, and its
guidance section renders from the step's admitted set. A step that does not
admit the tool leaves it out of declarations, guidance, and PTC program
bindings, and refuses a call to it as UNKNOWN_TOOL without reaching a
provider. Tests that execute web_search directly now run inside a resolved
step, as the executor requires for conditional registrations.
Docs, the readiness Agent Note, and the event producer/consumer table follow
the new mechanism; the tools README gains an explicit conditional-tools
anchor for cross-locale links.
A step's tool set no longer empties when the step is cancelled. The shared
pipeline already settles unstarted calls as cancelled; keeping admission lets
those calls keep their finalizers, and a wrapper result completed at
cancellation now reports cancellation instead of UNKNOWN_TOOL.
exit_plan_mode checks for a missing Agent explicitly instead of asserting it.
Document the activation types on the tools subsystem page, the turn/end code
for a failed tool condition, the replacement and no-set consequences in the
upgrade guide, and the admission rule in the parallel tool-call note.
The tool executor merge added ToolBatchInput.toolSet; the subsystem page's type-equivalence block now matches it. The architecture turn-flow line names step-admitted tool schemas in one line so the page stays within its word budget.
The default per-image limit is 50 MiB and the default per-side limit is
65,535 pixels, but the admission summaries in the attachment subsystem
page and the attachment-local README still named 20 MiB and 8192 pixels.
The session-controller note on the /api/file byte limit and the tool-fs
note on read_image source caps also named the old 20 MiB maxImageBytes
default.
Disclose the exit tool progressively instead of following every plan-mode
transition. The plan projection records whether a logged plan/mode ever
activated plan mode (stateVersion 4), and the tool's condition admits it
for a step whose selected state is active or once the Session has entered
plan mode. Leaving plan mode now changes only the guidance section, so an
addition-only route no longer drops a declaration from its cached prefix.
A call while plan mode is not committed still fails as unavailable outside
plan mode, and a Session that never entered plan mode does not list the
tool. The Web plan-review fixtures return to master's recording because the
request tool lists no longer change on exit.
Integrate exact origin/master b9bdd062c8ffd3dc234ebea7f5dff55ff26d87ad. Preserve the Session Markdown copy lifecycle and dictionary while adopting the Japanese locale, regenerate the client slot catalog, and add the Japanese quote-removal string required by the merged locale type.
Address the review of this pull request:
- A failed image upload keeps the Host's attachment refusal reason. The
thumbnail of a refused image names the reason instead of offering a
retry that cannot succeed, and Enter while uploads hold the send names
the first failure; a transport failure still offers retry, and an
image without a file name uses the pending-image label.
- An image upload stops reading at the smaller of the per-image and
per-message byte limits.
- A carried image draft moving to a Session that sends images inline
drops its upload instead of staging it again.
- The image upload ready state no longer carries an unread image ref.
- Docs describe stored-image admission and the command image path, and
the attachment rail test builds typed props instead of casting through
unknown.
Prompt admission counted stored images only toward the image count, so
two uploads that each fit alone could exceed maxMessageImageBytes once a
prompt cited both receipts. A staged image now records the byte length
of its upload, and admission counts stored and encoded images together
against both per-message limits before storing anything.
An image upload cancelled after its last chunk, or while its image was
stored, still received a receipt. The upload now checks cancellation
after the read and again before staging, as the file stream path does;
an image whose storage began stays stored, but no receipt is issued.
ctx.tools.register(definition, { when }) adds a synchronous or asynchronous
condition. AgentLoop resolves conditions once per proposed step with the
agent, the model selection that step preparation captured, and the turn
signal, before prompt assembly and agent/pre-step. The resulting
ResolvedToolSet governs tool declarations, Native dispatch, PTC bindings,
and nested calls for that step and its retries, and the turn disposes it
when the proposal is rejected or fails, when no step opens, and after the
step. A false condition removes the tool everywhere; a thrown condition
ends the turn with TOOL_ACTIVATION_FAILED. Calls whose registration was
replaced or removed during the step return UNKNOWN_TOOL.
system-prompt/assemble now transforms PromptPresentation without a tool
array, so tool declarations stay provider-owned. exit_plan_mode is declared
only for steps whose selected plan state is active, the same state that
renders plan guidance; it still rejects a call before the selection is
logged.
Model selection stays as master defines it; this change adds no model
selection event or Agent field.
An ordinary Session's composer now uploads each image draft through the
background upload queue as soon as it is added. The raw upload route stages
the body as a prompt image when the request names its media type: the Host
reads at most the per-image byte limit, then validates, normalizes, and
stores the image as prompt admission would. The prompt cites the receipt in
a file part; prompt admission resolves it to the stored image, applies the
image-input check, and counts stored images toward maxImagesPerMessage.
Send waits for every image receipt, and a failed image upload turns its
thumbnail into a retry control. Commands and subagent continuations keep
encoding images inline.
Bring master 45d1196d3fe into the release/dsh-0.2.1 squash commit of #6247
so the release commit stays an ancestor of master.
Conflict resolutions:
- apps/web/tsconfig.json, tsconfig.host.json: keep the entry-customization
e2e and master's Computer Use e2e entries.
- docs/subsystems/slots.{md,zh.md}: keep both added paragraphs; re-record the
slots, ui-primitives, and ui-workspace README translation pairs.
- ui-sidebar SidebarRoot.tsx and locales.ts: keep the More menu imports and
copy next to master's version-copy toast.
- apps/web/tests/agent-preset-selection.e2e.ts: keep the New Session
blank-reuse assertions, read presets through master's
sessionProjections.checkpoint() instead of the deprecated stateOf().
Follow-ups on master's side:
- ui-sidebar sidebar-root spec: give master's version-copy render the entry
pin props that SidebarRootInjected now requires.
- snapshots/web/steering/trajectory.expected.md: add the More conversation
views trigger to master's new Trajectory golden.

* docs: record region-owned pins for plugin entry customization
* refactor(ui): rebuild entry customization on region-owned pins and More menus
- Each navigation region (left sidebar, Conversation header, right sidebar
guide) persists its own unpinned list under
dsh.slot.manual-order.<list slot key>.v1, filters its own launchers, and
draws its own More button and Menu around its actions slot.
- ui-entry-customization only registers the shared menu rows (entries with
pin buttons, Browse other plugins, Create your plugin) into the three
actions slots and keeps no state.
- Remove ctx.layout.entryVisibility, the plugin store, left-sidebar drag
reordering, and agentPresetNavigation; ui-layout and ui-agent-preset match
release/dsh-0.2.1 again.
- Keep the release <nav> and Conversation tab-bar visibility conditions.
- Move the More glyph into ui-primitives as IconAppsAddOutline{Regular,Medium}.
* docs: compile the entry customization owner props example
* docs(ui): describe the wrapping Conversation tab row in the header comment
* fix(ui): return New Session to the Workspace blank and its unsent draft
- New Session (startSession without options) takes the blank-reuse path
again instead of creating a fresh Session on every call, which hid the
previous blank and its unsent draft since a5c9c2aaeef (#5775).
- A request that names an Agent preset skips blanks listing a different
preset, so Creator entries no longer take over an ordinary draft.
- Record the change in a v0.2.1-rc.2 upgrade guide; the Host refresh of a
stale loaded blank stays deferred (see the Agent Note).
* docs: regenerate the Cordis inspect catalog for New Session blank reuse
* fix(ui): keep the selected entry visible while unpinned
- Left-sidebar rows and View tabs keep the selected entry, with aria-current or aria-selected, until another entry is selected.
- Entry menu Creator action takes no region argument; the registration's region selects the prompt.
- Document the 2px panel-row and 32px View-tab gaps; drop commit hashes from the New Session Agent Note.
* fix(ui): leave a blank of another preset unstaged when starting Creator
startCreatorDraft stages cordis only when the main blank lists no preset or already lists cordis; navigation opens a separate Creator blank otherwise, so a Standard draft blank keeps its preset.
* feat(ui): choose whether a draft prompt replaces, appends to, or keeps an existing draft
- DraftInitializationOptions gains whenDraftExists ('replace' | 'append' | 'keep', default 'keep'); clearPreviousDraft stays and maps to 'replace' only when whenDraftExists is omitted.
- Append adds the prompt as new paragraphs after the existing text and references; attachments stay in every mode.
- The three Create your plugin entries append their regional prompt.
* test(web): align e2e with New Session blank reuse and the visible selected entry
* refactor(ui): share the draft paragraph writer between setDraft and appendDraft

The DeepSeek Search API returns a short `snippet` for display and a longer
`summary` written for model reading. Carry `summary` on `WebSearchSource`,
map it from the Search API, and render it in place of the snippet in
`web_search` output while the search card keeps the snippet.
`tool-web` collapses summary whitespace and caps each summary at the new
`searchSummaryMaxChars` setting (800 characters by default, the upper end of
the guide's typical range; live summaries measured 1,000-2,300). The cut keeps
surrogate pairs intact and ends in an ellipsis. The PTC tool output type gains
the optional field, so the affected system-prompt sidecars are refreshed, and
the web search round now exercises a multi-line summary.
The HTTP fetch provider resolved each hostname, rejected any non-public
answer, and pinned the connection. That refused every page behind
TUN-mode proxies with fake-IP DNS and did not confine a model that has
shell network access. Requests now go through the installed proxy
dispatcher and the system resolver with no address restriction.
HttpFetchResolver and the HttpFetchProvider resolver parameter are
removed; the upgrade guide covers the migration.
