src/tools/background-task/ — Background Task Tool Wrappers

Generated: 2026-03-02

OVERVIEW

18 files. Tool-layer wrappers for background_output and background_cancel. Does NOT implement the background execution engine — that lives in src/features/background-agent/. This directory provides the LLM-facing tool interface.

THREE TOOLS

Tool Factory Purpose
background_output createBackgroundOutput Get results from a running/completed background task
background_cancel createBackgroundCancel Cancel running task(s)
createBackgroundTask internal Shared factory used by both

KEY FILES

File Purpose
create-background-output.ts background_output tool: fetch task results by task_id
create-background-cancel.ts background_cancel tool: cancel by taskId or all=true
create-background-task.ts Shared tool factory with common params
clients.ts Client interfaces for background output and cancel
session-messages.ts Fetch session messages from OpenCode
full-session-format.ts Format full session output (messages, thinking blocks)
task-result-format.ts Format task result for LLM consumption
task-status-format.ts Format task status (running/completed/error)
message-dir.ts Temp directory for message exchange
truncate-text.ts Truncate large output to fit context
time-format.ts Human-readable duration formatting
delay.ts Polling delay utility
types.ts BackgroundTaskOptions, result/status types
constants.ts Timeout defaults, polling intervals

BACKGROUND OUTPUT MODES

background_output(task_id, block=false)  → check current status/result
background_output(task_id, block=true)   → wait until complete (timeout default: 120s)
background_output(task_id, full_session=true) → return full session transcript
background_output(task_id, message_limit=N) → last N messages only
background_output(task_id, include_thinking=true) → include thinking blocks

RELATIONSHIP TO BACKGROUND ENGINE

tools/background-task/  ← LLM tool interface
features/background-agent/  ← execution engine (BackgroundManager)

createBackgroundOutput queries BackgroundManager.getTask(task_id) — it does not manage task state.
