Brand Guidelines

Apply Anthropic’s official brand identity to presentations and documents. When to use:
  • Applying brand colors to artifacts
  • Using official typography standards
  • Ensuring consistent visual formatting
  • Styling with company design guidelines
Brand colors:
  • Main Colors: Dark (#141413), Light (#faf9f5), Mid Gray (#b0aea5), Light Gray (#e8e6dc)
  • Accent Colors: Orange (#d97757), Blue (#6a9bcc), Green (#788c5d)
Typography:
  • Headings: Poppins (with Arial fallback)
  • Body Text: Lora (with Georgia fallback)
Features:
  • Smart font application (24pt+ uses Poppins, body uses Lora)
  • Automatic fallback if custom fonts unavailable
  • Accent colors for shapes (cycles through orange/blue/green)
  • Maintains text hierarchy and readability
Technical details:
  • Uses system-installed fonts when available
  • RGB color values for precise brand matching

Doc Co-Authoring

Structured workflow for collaborative documentation creation. When to use:
  • Writing documentation, proposals, or technical specs
  • Creating decision docs or RFCs
  • Drafting PRDs or design documents
  • Any substantial writing task benefiting from structure
Three-stage workflow:

Stage 1: Context Gathering

Goal: Close the gap between user knowledge and Claude’s understanding.
  • Ask meta-questions about the document (type, audience, impact, format)
  • Encourage info dumping of all context
  • Read related documents and team discussions
  • Ask clarifying questions to fill gaps
  • Use integrations (Slack, Google Drive, etc.) when available

Stage 2: Refinement & Structure

Goal: Build document section by section through iteration. For each section:
  1. Ask clarifying questions about what to include
  2. Brainstorm 5-20 options for content
  3. User curates (keep/remove/combine)
  4. Draft the section
  5. Refine through surgical edits
  6. Repeat for all sections
Section ordering:
  • Start with sections having most unknowns
  • For decision docs: core proposal first
  • For specs: technical approach first
  • Summary sections last
User feedback:
  • Instead of editing directly, user indicates changes
  • Claude learns style preferences for future sections
  • Iterative refinement until section is complete

Stage 3: Reader Testing

Goal: Test document with fresh Claude to catch blind spots. With sub-agents (Claude Code):
  1. Predict reader questions
  2. Test with fresh Claude instance (no context)
  3. Run checks for ambiguity, false assumptions
  4. Report and fix issues
Without sub-agents (claude.ai):
  1. Generate reader questions
  2. User tests in fresh Claude conversation
  3. User reports what Reader Claude struggled with
  4. Fix gaps and iterate
Exit condition: Reader Claude consistently answers correctly Benefits:
  • Ensures document works when others read it
  • Catches assumptions and blind spots
  • Verifies doc works with Claude (for pasting into conversations)
  • Improves clarity before human readers see it

Internal Comms

Write various types of internal communications using company formats. When to use:
  • Writing 3P updates (Progress, Plans, Problems)
  • Creating company newsletters
  • Drafting FAQ responses
  • Status reports and leadership updates
  • Project updates and incident reports
Available formats: 3P Updates (Progress/Plans/Problems):
  • Team status updates
  • Weekly progress reports
  • Structured format for tracking work
Company Newsletters:
  • Company-wide communications
  • Announcements and updates
  • Engaging internal news
FAQ Answers:
  • Frequently asked questions
  • Standardized response format
  • Clear, helpful answers
General Comms:
  • Flexible format for other communications
  • Adaptable to various contexts
Process:
  1. Identify communication type
  2. Load appropriate guideline file from examples/
  3. Follow specific instructions for formatting and tone
  4. Gather necessary content
  5. Draft using company standards

Slack GIF Creator

Create animated GIFs optimized for Slack with custom animations. When to use:
  • Creating animated GIFs for Slack channels
  • Building custom emoji GIFs
  • Animating graphics for team communications
Slack requirements: Dimensions:
  • Emoji GIFs: 128x128 (recommended)
  • Message GIFs: 480x480
Parameters:
  • FPS: 10-30 (lower = smaller file size)
  • Colors: 48-128 (fewer = smaller file size)
  • Duration: Under 3 seconds for emoji GIFs
Core workflow:
from core.gif_builder import GIFBuilder
from PIL import Image, ImageDraw

# Create builder
builder = GIFBuilder(width=128, height=128, fps=10)

# Generate frames
for i in range(12):
    frame = Image.new('RGB', (128, 128), (240, 248, 255))
    draw = ImageDraw.Draw(frame)
    # Draw animation using PIL primitives
    builder.add_frame(frame)

# Save with optimization
builder.save('output.gif', num_colors=48, optimize_for_emoji=True)
Drawing graphics:
  • Use PIL ImageDraw primitives (circles, polygons, lines, rectangles)
  • Thicker lines (width=2+) look more polished
  • Add visual depth with gradients and layering
  • Use vibrant, complementary colors
  • Create complex shapes by combining primitives
Animation concepts:
  • Shake/Vibrate: Oscillating position offsets
  • Pulse/Heartbeat: Rhythmic size scaling
  • Bounce: Gravity-based motion with easing
  • Spin/Rotate: Rotation around center
  • Fade In/Out: Alpha channel animation
  • Slide: Off-screen to position movement
  • Zoom: Scale and crop effects
  • Explode: Particle burst radiating outward
Available utilities:
  • GIFBuilder: Frame assembly and optimization
  • Validators: Check Slack requirements
  • Easing functions: Smooth motion (ease_in, ease_out, bounce_out, etc.)
  • Frame helpers: Blank frames, gradients, shapes, text
Optimization strategies:
  • Fewer frames (lower FPS or shorter duration)
  • Fewer colors (num_colors=48)
  • Smaller dimensions (128x128)
  • Remove duplicate frames
  • Emoji optimization mode
Philosophy:
  • Provides knowledge and utilities, not rigid templates
  • Flexibility to create custom animations
  • Use PIL primitives for full creative control
  • Combine concepts for unique effects
