# Delegation intent: Hook context SystemItem append sink
## Intent
Implement the first step in the Task state/reminder cleanup sequence: add event-specific Hook context support with a host-mediated durable `SystemItem` append handle, while keeping Hook return actions as per-hook-point flow-control actions.
This is the prerequisite for moving TaskStore/reminder logic into the Task feature. Do not move TaskStore or Task reminders in this ticket.
## Worktree / branch
- worktree: `/home/hare/Projects/yoi/.worktree/hook-context-system-item-sink`
- branch: `work/hook-context-system-item-sink`
## Requirements
- Evolve the public Pod Hook API so Hook handlers receive event-specific context values rather than only bare summary inputs where necessary.
- Preserve the existing per-hook-point action/output types.
- Do not collapse actions into one global `HookDecision`.
- Add a host-created typed handle for durable model-visible `SystemItem` append.
- Suggested naming: `SystemItemAppendHandle`, `SystemItemSink`, or equivalent.
- Constructors/fields must stay host-private; feature/hook code can only use handles the host provides.
- The handle must not expose raw `llm_worker::Item`, raw history writers, raw event senders, raw `Pod`, raw `Worker`, or `NotifyBuffer`.
- The append path must use existing durable history semantics:
- host-controlled pending append / commit path;
- `LogEntry::SystemItem`;
- `Event::SystemItem`;
- model context visibility only after durable commit.
- The initial approved system-item requests should be narrow.
- Support what is needed for a future `TaskReminder` hook, and notification-like system items only if this falls out naturally from existing `SystemItem` machinery.
- Do not introduce arbitrary `llm_worker::Item` append or generic plugin event channels.
- Keep built-in internal modules distinct from external-plugin authority approval.
- It is okay to add scaffolding so internal hooks can receive the handle by host policy.
- Do not implement external-plugin approval or WASM imports in this ticket.
- Preserve current observable behavior.
- Current Task reminders should continue to be emitted by existing `PodInterceptor` logic until the follow-up ticket moves them.
- Existing Hook tests and permission hook behavior must continue to pass.
## Non-goals
- Moving `TaskStore` ownership into the Task feature.
- Moving `TaskReminderState` or `PodInterceptor` reminder logic.
- TUI UI/dialog work.
- Generic event channel / arbitrary UI payloads.
- External plugin loading or package approval.
- Changing ToolRegistry / PreToolCall permission behavior.
- Reintroducing raw `Item` injection, `ContinueWith(Vec<Item>)`, no-result tool skip, or arbitrary `ToolResult` construction.
## Suggested files
- `crates/pod/src/hook.rs`
- `crates/pod/src/ipc/interceptor.rs`
- `crates/pod/src/pod.rs`
- `crates/pod/src/controller.rs`
- `crates/session-store/src/system_item.rs` or wherever `SystemItem` request/serialization is defined
- existing Hook tests in `crates/pod/src/**`
## Validation
Run at least:
- focused Hook context / SystemItem sink tests added by this ticket
- `cargo test -p pod hook --lib`
- `cargo test -p pod --lib`
- `cargo test -p llm-worker --lib`
- `cargo check --workspace --all-targets`
- `cargo fmt --check`
- `./tickets.sh doctor`
- `git diff --check`
Run `nix build .#yoi` if feasible.
## Escalate if
- Implementing the handle requires changing session/history commit semantics.
- The only easy path is to expose raw `Item`, raw history writers, raw event senders, or `Pod`/`Worker` internals.
- Hook action types would need to be merged into one generic return type.
- Current Task reminder behavior would change before the Task ownership follow-up.
## Completion report
Report:
- worktree path / branch
- commit hash
- changed files
- Hook context/action API changes
- SystemItem append handle design and path to durable commit
- tests added/updated
- validation results
- unresolved risks/follow-ups
- whether ready for external review
