Keeps the apply_patch toolview registration with master's file-menu inject,
takes master's shortened slot JSDoc, re-adds the seven filesystem type-equiv
manifest entries, regenerates the event matrix and client catalogs, moves the
fs-observation-policy upgrade guide under v0.2.2-alpha.2 with the matching
fs-patch version, and refreshes the two SDK scenarios master added for the
write and edit guidance change.
Takes master's re-measured npm install-layout budget, which covers this
branch's graph, and regenerates the Cordis API, event matrix, client slot,
and tool catalogs on the merged tree.
Resolves the headless snapshot runner (keeps both the readonly-patch-directory
and cua-script-guidance workspace setups), regenerates the client slot and tool
catalogs with their pairing record, adds the apply_patch tool title to the five
locales master introduced, and refreshes the apply-patch system-prompt pin for
master's subagent guidance change.
Add an authored headless scenario that appends a changed prompt and then replaces a surface node before the third step. The unchanged-rendering series start must keep both prompt versions and write no system/message event; the scenario fails against the pre-fix projection. Also tighten the tool-series-start assertions and make the prefix premise explicit.
Clarify the SystemPromptDecisionInput.startsSeries contract (a new request series no longer implies consolidation), record the tool-schema series-start exception consistently in the decision and consequences, and correct the complete-declaration attribution to the unsupported-route projection.
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.
Update the capability decision rule, both READMEs, the EventMap JSDoc and generated catalogs. Add the bug-fix Agent Note that records the incident evidence, the decision, rejected alternatives and consequences, and cross-link it from the in-history decision note.
An in-history route carries prompt updates as later system nodes while node 0 stays stale. A surface replacement (compaction, tool-result prune, image offload) starts a new request series, and the projection used to re-baseline node 0 even when the rendering already matched the latest surviving node: it emptied that node and wrote identical text into node 0, so the request differed at its first message and the provider prefix cache missed from the first token (#6973).
Re-baseline node 0 only when the effective text must move: an incapable route, an empty rendering, or a series start whose latest surviving non-empty node differs from the rendering. A capable series start with matching text emits no system event; the loop still logs the request series and rebuilds declarations. Retry compaction still folds the prompt to the head when it shadows the latest node.
A compaction replacement after an appended in-history prompt starts a new request series, and the projection folds the prompt back into node 0 although the effective text is unchanged. The request moves the system segment to wire message 0, so the provider prefix cache misses from the first token (#6973).
The regression fails before the fix: the third request carries one system text ("prompt two") instead of keeping the appended node behind the cached prefix.
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.
