debug-toolbar: Command for Claude Code

Intelligent Implementation Workflow

You are implementing the feature from PRD: $ARGUMENTS

Pre-Implementation Checklist

1. Load PRD from specs/active/{slug}/prd.md
2. Load pattern analysis from specs/active/{slug}/patterns/
3. Read similar implementations identified in PRD
4. Consult pattern library at specs/guides/patterns/

Critical Rules

1. PATTERN COMPLIANCE - Follow patterns from similar features
2. NO OVER-ENGINEERING - Only implement what's in the PRD
3. TYPE SAFETY - Use PEP 604 (T | None), future annotations
4. TEST READY - Design for testability
5. INCREMENTAL - Commit logically, not at the end

---

Phase 1: Context Loading

Load intelligence context:

# Verify PRD exists
cat specs/active/{slug}/prd.md

# Load patterns
cat specs/active/{slug}/patterns/analysis.md

# Load research
cat specs/active/{slug}/research/plan.md

Read similar implementations:

• Read files identified in PRD's "Similar Implementations" section
• Extract exact patterns to follow

Output: "✓ Phase 1 complete - Context loaded"

---

Phase 2: Implementation Planning

Break down into atomic tasks:

For each file to create/modify:

1. Identify dependencies
2. Plan implementation order
3. Note patterns to apply

Update workspace:

echo "## Implementation Plan" >> specs/active/{slug}/tmp/progress.md

Output: "✓ Phase 2 complete - Implementation planned"

---

Phase 3: Core Implementation

Follow the Panel pattern if creating a panel:

"""Panel implementation."""

from __future__ import annotations

from typing import TYPE_CHECKING, Any, ClassVar

from debug_toolbar.core.panel import Panel

if TYPE_CHECKING:
    from debug_toolbar.core.context import RequestContext


class NewPanel(Panel):
    """Description."""

    panel_id: ClassVar[str] = "NewPanel"
    title: ClassVar[str] = "New Panel"
    template: ClassVar[str] = "panels/new_panel.html"
    has_content: ClassVar[bool] = True

    async def generate_stats(self, context: RequestContext) -> dict[str, Any]:
        """Generate statistics."""
        return {}
