action-cards owns the propose_action tool, the actionCards projection of
proposals and decisions, the act Remote and the card status notice; card
kinds register an action name, skill, details schema, verbs and handler.
The tool is admitted per Agent only after a registered kind's skill loads.
client-ui-action-cards draws the card frame below the completed answer,
lets kinds register a body per action and adds the propose_action
process row.
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.
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.
Pass execution-specific phrases directly to the run_code flavor factory and render SDK instructions from explicit program-format branches. Keep all emitted text byte-identical while removing coupling to exact shared prose. Validate the owning tests with full scoped coverage, focused session/SDK replays, and a complete build.
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.
Preserve the persistent runtime package description with master's alpha.2 version and locale exports. Refresh the two PTC prompt snapshots for the current plan-tool result type.
Validation: full build, 434 focused tests (one skipped), two built-runtime tests, two selected snapshots, package metadata, and all 43 doc-sync checks passed.
