Agent Harness
Subcommand Routing
When invoked as /agent-harness <subcommand>, route to the appropriate workflow:
| Subcommand | Action |
|---|---|
init <name> |
Run python3 scripts/init_project.py "<name>" --project-dir "$(pwd)" |
sprint [req] |
Execute Sprint Agent workflow (see references/sprint-agent.md) |
code |
Execute Coding Agent workflow (see references/coding-agent.md) |
996 |
Execute 996 parallel orchestration (see references/996-agent.md) |
status |
Run python3 scripts/status.py --project-dir "$(pwd)" |
archive |
Run archive workflow |
force-archive |
Run force archive workflow |
help or empty |
Show available commands |
Usage examples:
/agent-harness init "My Project"- Initialize new project/agent-harness sprint "Add authentication"- Plan sprint/agent-harness code- Start coding session/agent-harness 996- Execute parallel coding with subagent orchestration/agent-harness status- Show status
CRITICAL: Always operate on files in the current project directory, NOT in the skill directory. At the start of every workflow, run python3 scripts/resolve_project_dir.py to get the correct absolute path. Use this path for ALL reads/writes of features.json and progress.md.
Framework for executing complex, multi-session projects using Sprint-Coding agent cycles.
Overview
Agent Harness enables Claude to manage long-running projects by:
- Sprint Agent: Plans features and breaks down requirements
- Coding Agent: Implements features one at a time
- 996 Agent: Orchestrates parallel feature implementation with subagents
- Progress Tracking: Maintains context across sessions
- Quality Gates: Ensures working code at each step
Commands
Agent Harness provides slash commands with tab completion. Type /agent-harness to see all commands.
/agent-harness
Show available commands and usage.
Output:
Agent Harness Commands:
/agent-harness init <name> - Initialize new project tracking files
/agent-harness sprint [req] - Create or update sprint with feature breakdown
/agent-harness code - Start coding session for next feature
/agent-harness 996 - Execute parallel coding with subagent orchestration
/agent-harness status - Show current project status
/agent-harness archive - Archive completed sprints
/agent-harness force-archive - Force archive ALL sprints (including incomplete)
/agent-harness init <name>
Initialize new project tracking files.
Example: /agent-harness init My App
Actions:
- Create
features.jsonandprogress.md - Run
python3 scripts/init_project.py "My App" - Commit the initialized files:
git add features.json progress.md && git commit -m "chore: initialize project tracking"
/agent-harness sprint [requirements]
Create or update sprint with feature breakdown.
Examples:
/agent-harness sprint- Review current sprint and plan next/agent-harness sprint Add user authentication with email and social login/agent-harness sprint Build dashboard with charts and filters
Actions:
- Archive completed sprints (if any)
- Analyze requirements
- Break into atomic features with acceptance criteria
- Update only
features.jsonandprogress.md— do NOT create extra files like summary documents - Display sprint planning summary in terminal
- Ask user to confirm the sprint plan before committing
- After user confirms, commit:
git add features.json progress.md && git commit -m "chore: sprint planning - <sprint-name>" - Read sprint-agent.md for detailed workflow
/agent-harness code
Start coding session for next feature.
Actions:
- Review
progress.mdandfeatures.json - Select next pending feature
- Implement following session protocol
- Commit code after implementation:
git add -A && git commit -m "feat(<scope>): <description>" - Read coding-agent.md for protocol
/agent-harness 996
Execute parallel coding tasks with subagent orchestration.
Examples:
/agent-harness 996- Run parallel orchestration with default settings/agent-harness 996 --max-parallel=3- Limit to 3 concurrent subagents
Actions:
- Check for uncompleted sprint
- Analyze dependencies and file conflicts
- Dispatch subagents for parallel execution
- Verify results and update tracking files
- Commit:
git add -A && git commit -m "chore: 996 orchestration complete - N features" - Read 996-agent.md for protocol
Use when: You want to accelerate sprint completion by running multiple coding tasks in parallel.
/agent-harness status
Show current project status.
Output:
- Current sprint and goal
- Feature completion statistics
- Next recommended feature
- Run
python3 scripts/status.py
/agent-harness archive
Archive completed sprints.
Actions:
- List completed sprints
- Move to
.agent-harness/archived/ - Run
python3 scripts/archive_sprint.py - Commit:
git add -A && git commit -m "chore: archive completed sprint"
/agent-harness force-archive
Force archive ALL sprints (including incomplete ones).
Warning: This will archive all sprints regardless of their status.
Actions:
- List all sprints to be archived
- Confirm with user
- Move all to
.agent-harness/archived/ - Run
python3 scripts/archive_sprint.py --force - Commit:
git add -A && git commit -m "chore: force archive all sprints"
Quick Start
python3 scripts/init_project.py "Project Name" -d "Description"
python3 scripts/status.py
python3 scripts/validate_structure.py
Workflow
1. Sprint Planning (Sprint Agent)
When: New project or iteration
- Analyze user requirements
- Break into atomic features with acceptance criteria
- Order by dependencies
- Update
features.jsonandprogress.md
→ Read references/sprint-agent.md for workflow, schemas, and examples
2. Feature Implementation (Coding Agent)
When: Each development session
Session Protocol:
| Phase | Actions |
|---|---|
| Start | pwd → read progress.md → git log → run lint/build |
| Work | Select ONE feature → implement → test |
| End | Update progress.md → update features.json → commit |
→ Read references/coding-agent.md for protocol, testing, and schemas
3. Iterate
Loop: Sprint Agent → Coding Agent → Coding Agent → ... → Sprint Agent
Core Files
| File | Purpose |
|---|---|
features.json |
Sprint and feature tracking |
progress.md |
Session log - add entries at top |
AGENTS.md |
Project-specific instructions |
→ See references/sprint-agent.md or references/coding-agent.md for schemas
Scripts
All scripts support --project-dir / -p to specify the project directory. When using slash commands, --project-dir "$(pwd)" is passed automatically.
python3 scripts/resolve_project_dir.py [-s dir] # Resolve project directory
python3 scripts/init_project.py <name> [-d desc] [-p dir] # Initialize tracking
python3 scripts/status.py [-p dir] # Show status
python3 scripts/validate_structure.py [-p dir] # Validate features.json
python3 scripts/archive_sprint.py [-p dir] [--list|--dry-run] # Archive completed sprints
CRITICAL: Always prefix with $env:PYTHONIOENCODING="utf-8"; when running scripts (required for Windows GBK compatibility).
Critical Rules
- One Feature Per Session - Don't implement multiple
- Always Leave Working Code - Never break the build
- Test End-to-End - Verify as user would experience
- Commit Frequently - Small commits enable rollback
- Never Delete Features - Only change status
- Use Progress Log - Record every session
