The TUI's referenced-prompt snapshot now rides the prompt's own admission transaction instead of a pre-admission inject: while idle, a one-shot prepended agent/prompt-submit wrapper appends the snapshot to the allow decision's additionalContexts, so a blocking hook discards the prompt and its attached context together instead of stranding the snapshot in history for the next unrelated prompt. A prompt discarded before admission releases the wrapper; steering keeps the inject path since it bypasses admission and drains at the same boundary. The session-reference snapshot adapter pinned the old context-before-prompt order; the branch-wide order (prompt first, its contexts after) is now asserted and the fixture re-recorded. tool-tasks drops the last consumer of the removed thrown-disposed contract: completion notices now inject unconditionally, which is well-defined during owner teardown — the loop treats disposal like any cancel, so the notice appends as durable idle context (persisted for resume while the session is attached, dropped with the detached log after). README pair and the owner-disposal tests state the new delivery contract.
tasks/ — background task capability family
English | 中文
The shared home for background-task ids, owner isolation, reads, cancellation, waiting, and completion notices. Bash, subagents, and future long-running tools use one model-facing protocol. See the background-task runtime Agent Note.
| Package | ctx key | Role |
|---|---|---|
tasks (@deepseek-ai/dsh-tasks) |
ctx.tasks |
The registry service: branded <kind>-N ids, owner-fenced read/kill/wait/list, settlement bookkeeping, the awaited owner-cleanup path, and the attachSurface misconfiguration fence |
tool-tasks (@deepseek-ai/dsh-tool-tasks) |
— | The model-facing control surface: task_output, task_list, task_kill, the completion-notice injection, and the background-habit prompt section |
The registry owns state across producer or surface reloads; the tool package owns presentation. Producers register execution hooks through ctx.tasks.start and own whether their config exposes run_in_background.
