Task Management

← Docs index

This guide covers task creation, lifecycle behavior, task metadata, and operational workflows.

Task Creation Options

1) Quick Entry (dashboard)

Use the inline input on board/list view:

• Type description
• Press Enter
• Task is created in planning

2) Plan Mode (AI interview)

Use the 💡 button to open planning mode:

• AI asks clarifying questions
• Produces summary + key deliverables
• Create one task or Break into Tasks (multi-task generation with dependencies)

3) Subtask Breakdown Dialog

Use the 🌳 button:

• Generate 2–5 candidate subtasks
• Drag to reorder
• Add dependencies only on earlier items
• Create tasks in one action

4) Expanded Controls

Expand the creation panel (▼) to access additional controls:

• Refine (✨) — Improve the description with AI
• Deps (🔗) — Link existing tasks as dependencies
• Attach — Add image attachments
• Models (🧠) — Set per-task model overrides (executor, validator, planning)
• Agent — Assign an agent to the task
• Review — Set review rigor level (None, Plan Only, Plan and Code, Full)
• Browser Verify — Enable browser verification workflow step

5) CLI creation

fn task create "Fix API timeout handling"
fn task plan "Implement role-based access control"
fn task create "Bug" --attach screenshot.png --depends FN-002

Task Lifecycle

Fusion task columns:

1. planning — idea intake; AI writes a full plan
2. todo — ready for scheduling
3. in-progress — executor active in isolated worktree
4. in-review — implementation complete; awaiting finalization
5. done — merged/finalized
6. archived — preserved history, optionally cleaned from filesystem

Lifecycle commands

fn task move FN-001 todo
fn task merge FN-001
fn task archive FN-001
fn task unarchive FN-001

Task Execution Modes

Each task has an execution mode that controls how the executor agent approaches the task:

Mode	Description
standard	Full execution with complete review workflow (default)
fast	Expedited execution with minimal overhead for simple tasks

Fast Mode Bypassed Gates

When executionMode: "fast", the following automated review/validation gates are bypassed:

Gate	Standard Mode	Fast Mode
review_step tool enforcement	Available to executor agent	Not injected
Pre-merge workflow-step execution	Runs configured steps	Skipped
Workflow revision loop	Enabled (feedback → fix → re-review)	Disabled

Fast Mode Mandatory Gates

The following quality gates remain enforced in fast mode:

Gate	Behavior
task_done requirement	Agent must call task_done() to complete
Completion blocker checks	Tests, build, and typecheck from PROMPT.md still enforced
Post-merge workflow steps	Run as normal (merger-owned)

Execution Mode Matrix

Feature	Standard	Fast
Executor agent session	Full prompt + tools	Full prompt (minus review_step)
Pre-merge workflow steps	✅ Run	❌ Bypassed
review_step tool	✅ Available	❌ Not available
Post-merge workflow steps	✅ Run	✅ Run
Completion blockers (test/build/typecheck)	✅ Enforced	✅ Enforced
task_done() requirement	✅ Required	✅ Required

Setting Execution Mode

Execution mode can be set during task creation or editing:

• Via API: Include executionMode field in task create/update payload
• Via dashboard: Select execution mode in the task creation dialog or task detail modal
• Values: "standard" (default) or "fast"

Example API payload:

{
  "description": "Simple fix",
  "executionMode": "fast"
}

Task Detail Modal (Dashboard)

The task detail modal exposes multiple tabs:

• Details — primary metadata and description
• Steps — progress across plan/implementation steps
• Log — task event history
• Changes — merge diff/change summary
• Workflow — workflow step results (pass/fail/skip)
• Comments — collaboration thread + steering controls
• Model — per-task model overrides and thinking level

PROMPT.md Plan Structure

After planning, each task gets a structured PROMPT.md with sections like:

• Mission
• Dependencies
• Context to read first
• File scope
• Steps
• Acceptance criteria
• Guardrails / Do NOT list
• Build/test/typecheck requirements

This file is the contract for execution and review.

Task Comments vs Steering Comments

• Task comments (fn task comment) are general collaboration notes.
• Steering comments (fn task steer) are execution guidance for the running agent.

Steering comments can be injected mid-run into active executor sessions.

Refinement Tasks

fn task refine <id> creates a new planning task that depends on the original done/in-review task.

Example:

fn task refine FN-042 --feedback "Add explicit rollback tests for partial failure"

Behavior:

• New title format: Refinement: <source label>
• New task depends on source task
• Created in planning

Archive and Restore

Archive behavior

• fn task archive <id> moves done task to archived
• Cleanup mode can persist compact metadata and remove the task directory

Cleanup behavior

• Archived entries are persisted as compact archive snapshots (current runtime stores these in SQLite archivedTasks; legacy docs may refer to .fusion/archive.jsonl)
• Task directory (task.json, PROMPT.md, agent.log, attachments) can be removed

Compact archive entry format

Archive entries preserve key metadata needed for restoration, including:

• id, title, description, priority, column
• dependencies, steps, currentStep
• size, reviewLevel, prInfo, issueInfo
• attachments metadata
• task log
• timestamps (createdAt, updatedAt, columnMovedAt, archivedAt)
• model override fields (modelProvider, modelId, validatorModel*, planningModel*)

agent.log content is intentionally not preserved in compact archive entries.

Restore behavior

fn task unarchive <id>:

• Restores archive entry if directory is missing
• Rebuilds PROMPT.md
• Moves task to done
• Logs “Task restored from archive” when recovering from compact archive entry

GitHub Issue Import and PR Creation

Import issues:

fn task import owner/repo --labels bug --limit 20
fn task import owner/repo --interactive

Create PR for in-review task:

fn task pr-create FN-120 --title "Fix flaky auth flow" --base main

Completion Modes (mergeStrategy)

• direct: local squash-merge flow into target branch
• pull-request: PR-first completion flow via GitHub checks/reviews

Configured via settings.

Per-Task Model Overrides

Each task may override:

• Executor model (modelProvider + modelId)
• Validator model (validatorModelProvider + validatorModelId)
• Planning model (planningModelProvider + planningModelId)
• Thinking level (off|minimal|low|medium|high)

Overrides are configured from the task model tab or task creation actions.

Review Level

Review levels control the rigor of the review process for a task:

Level	Name	Description
0	None	No review
1	Plan Only	Review only the plan
2	Plan and Code	Review both the plan and implementation
3	Full	Full review with all checks

Review level can be set during task creation (in the New Task dialog under More options) or when editing a task (in the task detail modal).

The review level affects how the reviewer agent evaluates the task but does not override workflow steps or model presets.

Model Presets and Auto-Selection by Size

Project settings support reusable model presets:

• modelPresets
• autoSelectModelPreset
• defaultPresetBySize (S, M, L)

Users can apply presets at task creation; manual model selection can override them.

AI Title Summarization

When autoSummarizeTitles is enabled and a task has a long untitled description, Fusion can auto-generate a concise title.
