/feature — Add a Feature

Fast path for adding a feature to an existing project. Skips the /think diagnostic and runs the full sprint via skill invocations.

/feature Add import from JSON/CSV to restore backups

Setup

Before anything else, ensure the project is configured. Run this once (skips if already done):

[ -f .claude/settings.json ] || ~/.claude/skills/nanostack/bin/init-project.sh

Session

Initialize the sprint session:

~/.claude/skills/nanostack/bin/session.sh init feature

Then run session.sh phase-start plan. This activates the phase gate — git commit will be blocked until review, security, and qa are complete.

Process

You are an autonomous orchestrator. You run the entire sprint without stopping between phases. Do NOT wait for user input between steps. Do NOT ask "should I continue?" or "ready for review?". Invoke each skill, wait for it to complete, then immediately invoke the next one. The only reasons to stop are blocking issues or critical vulnerabilities.

Step 1: Context

Read existing artifacts to understand the project:

~/.claude/skills/nanostack/bin/find-artifact.sh think 30
~/.claude/skills/nanostack/bin/find-artifact.sh plan 30
~/.claude/skills/nanostack/bin/find-artifact.sh ship 30

Read the checkpoint summaries. If no artifacts exist, read the codebase directly.

Step 2: Plan

Use Skill tool: skill="nano"

Wait for /nano to complete. It saves its own artifact. Then immediately build.

Step 3: Build

Build the feature. Do not ask for approval. The plan was the contract.

Step 4: Review + Security + QA (parallel)

These three phases are independent. They all read the build output but don't depend on each other. Launch all three using the Agent tool in a single message with three parallel tool calls:

Agent: subagent_type="general-purpose", prompt="Run /review on this project. Use Skill tool: skill='review'"
Agent: subagent_type="general-purpose", prompt="Run /security on this project. Use Skill tool: skill='security'"
Agent: subagent_type="general-purpose", prompt="Run /qa on this project. Use Skill tool: skill='qa'"

If parallel agents are not available, fall back to sequential:

Use Skill tool: skill="review"
Use Skill tool: skill="security"
Use Skill tool: skill="qa"

If any phase finds blocking issues or critical vulnerabilities: fix them, then re-run that phase only.

Feature: review + security + qa complete. Running /ship...

Step 7: Ship

Use Skill tool: skill="ship"

/ship commits, creates PR if remote exists, generates sprint journal, runs /compound, and shows the result with next feature suggestions.

Rules

• Do not stop between phases. This is the most important rule. Plan → build → review → security → qa → ship runs as one continuous flow. No pauses, no questions, no confirmations.
• Each skill is invoked via the Skill tool, not implemented inline.
• Each skill saves its own artifact. You do not save artifacts — the skills do.
• Between steps, show one line of status: Feature: review complete. Running /security...
• Stop ONLY if a skill finds a blocking issue or critical vulnerability you cannot fix.
• If the feature already exists in the codebase, tell the user and suggest alternatives.
