Arch Start

Step 2: Start the Session

Run this command:

python scripts/arch_session.py start

This will:

• Set phase to "executing"
• Set current_step to the first step ID
• Print the current step details

Step 3: Read Current Step Details

Read .claude/arch/TASK_GRAPH.json and find the current step. Display:

Current Step: [id] - [title]
Goal: [goal]
Allowed Paths: [allowed_paths]
Verification: [verification commands]
Success Criteria: [success_criteria]

Step 4: Implement the Step

Implement the goal described in the current step.

CRITICAL CONSTRAINTS:

• ONLY modify files that match allowed_paths for this step
• Do NOT touch any files outside the allowed paths
• Do NOT skip ahead to other steps
• Keep changes minimal and focused on the step's goal

Step 5: Run Verification

After implementing, run each verification command listed for the step:

# Run each command from the step's "verification" array
[verification command 1]
[verification command 2]
...

Step 6: Report and Stop

After verification, output the results and stop:

If verification passes:

Step [id] implementation complete.
Verification passed.

Run /arch-next to advance to the next step.

If verification fails:

Step [id] implementation complete.
Verification FAILED:
[error output]

Fix the issues and re-run verification, then run /arch-next.

Constraints

• Write boundaries enforced: Only modify files matching allowed_paths for the current step
• One step at a time: Do not implement multiple steps in one invocation
• Verification required: Always run verification commands before stopping
• User controls progression: Wait for user to run /arch-next to advance
