Standard: Task JSON Schema

Purpose: JSON schema reference for task management files

Last Updated: 2026-01-11

Core Concepts

Task management uses two JSON file types:

• task.json - Feature-level metadata and tracking
• subtask_NN.json - Individual atomic tasks with dependencies

Location: .tmp/tasks/{feature-slug}/ (at project root)

task.json Schema

Field	Type	Required	Description
id	string	Yes	kebab-case identifier
name	string	Yes	Human-readable name (max 100)
status	enum	Yes	active / completed / blocked / archived
objective	string	Yes	One-line objective (max 200)
context_files	array	No	Paths to lazy-load
exit_criteria	array	No	Completion conditions
subtask_count	int	No	Total subtasks
completed_count	int	No	Done subtasks
created_at	datetime	Yes	ISO 8601
completed_at	datetime	No	ISO 8601

---

subtask_NN.json Schema

Field	Type	Required	Description
id	string	Yes	{feature}-{seq}
seq	string	Yes	2-digit (01, 02)
title	string	Yes	Task title (max 100)
status	enum	Yes	pending / in_progress / completed / blocked
depends_on	array	No	Sequence numbers of dependencies
parallel	bool	No	True if can run alongside others
context_files	array	No	Task-specific context
acceptance_criteria	array	No	Binary pass/fail conditions
deliverables	array	No	Files to create/modify
agent_id	string	No	Set when in_progress
started_at	datetime	No	ISO 8601
completed_at	datetime	No	ISO 8601
completion_summary	string	No	What was done (max 200)

Status Transitions

pending → in_progress   (by working agent, when deps satisfied)
in_progress → completed (by TaskManager, after verification)
* → blocked             (by either, when issue found)
blocked → pending       (when unblocked)

---

Parallel Flag

• parallel: true = Isolated task, can run alongside others
• parallel: false = May affect shared state, run sequentially

Use task-cli.ts parallel to find all parallelizable tasks ready to run.

Example

{
  "id": "auth-system-02",
  "seq": "02",
  "title": "Create JWT service",
  "status": "pending",
  "depends_on": ["01"],
  "parallel": false,
  "context_files": [".opencode/context/development/backend/auth/jwt-patterns.md"],
  "acceptance_criteria": ["JWT tokens signed with RS256", "Tests pass"],
  "deliverables": ["src/auth/jwt.service.ts"]
}
