Create Glyph

Create R-based pictogram glyphs for skill, agent, or team icons in the viz/ visualization layer. Each glyph is a pure-ggplot2 function that draws a recognizable shape on a 100x100 canvas, rendered with a neon glow effect to transparent-background WebP.

When to Use

• A new skill, agent, or team has been added and needs a visual icon
• An existing glyph needs replacement or redesign
• Batch-creating glyphs for a new domain of skills
• Prototyping visual metaphors for entity concepts

Inputs

• Required: Entity type — skill, agent, or team
• Required: Entity ID (e.g., create-glyph, mystic, r-package-review) and domain (for skills)
• Required: Visual concept — what the glyph should depict
• Optional: Reference glyph to study for complexity level
• Optional: Custom --glow-sigma value (default: 4)

Procedure

Step 1: Concept — Design the Visual Metaphor

Identify the entity being iconified and choose a visual metaphor.

1. Read the entity's source file to understand its core concept:
   • Skills: skills/<id>/SKILL.md
   • Agents: agents/<id>.md
   • Teams: teams/<id>.md
2. Choose a metaphor type:
   • Literal object: a flask for experiments, a shield for security
   • Abstract symbol: arrows for merging, spirals for iteration
   • Composite: combine 2-3 simple shapes (e.g., document + pen)
3. Reference existing glyphs for complexity calibration:

Complexity Tiers:
+----------+--------+-------------------------------------------+
| Tier     | Layers | Examples                                  |
+----------+--------+-------------------------------------------+
| Simple   | 2      | glyph_flame, glyph_heartbeat              |
| Moderate | 3-5    | glyph_document, glyph_experiment_flask    |
| Complex  | 6+     | glyph_ship_wheel, glyph_bridge_cpp        |
+----------+--------+-------------------------------------------+

4. Decide on a function name: glyph_<descriptive_name> (snake_case, unique)

Expected: A clear mental sketch of the shape with 2-6 planned layers.

On failure: If the concept is too abstract, fall back to a related concrete object. Review existing glyphs in the same domain for inspiration.

Step 2: Compose — Write the Glyph Function

Write the R function that produces ggplot2 layers.

1. Function signature (immutable contract):

   glyph_<name> <- function(cx, cy, s, col, bright) {
     # cx, cy = center coordinates (50, 50 on 100x100 canvas)
     # s = scale factor (1.0 = fill ~70% of canvas)
     # col = domain color hex (e.g., "#ff88dd" for design)
     # bright = brightened variant of col (auto-computed by renderer)
     # Returns: list() of ggplot2 layers
   }
   

2. Apply scale factor * s to ALL dimensions for consistent scaling:

   r <- 20 * s        # radius
   hw <- 15 * s       # half-width
   lw <- .lw(s)       # line width (default base 2.5)
   lw_thin <- .lw(s, 1.2)  # thinner line width
   

3. Build geometry using available primitives:

   Geometry	Usage
   ggplot2::geom_polygon(data, .aes(x, y), ...)	Filled shapes
   ggplot2::geom_path(data, .aes(x, y), ...)	Open lines/curves
   ggplot2::geom_segment(data, .aes(x, xend, y, yend), ...)	Line segments, arrows
   ggplot2::geom_rect(data, .aes(xmin, xmax, ymin, ymax), ...)	Rectangles
   ggforce::geom_circle(data, .aes(x0, y0, r), ...)	Circles

4. Apply the color strategy:

   Alpha Guide:
   +----------------------+------------+--------------------------+
   | Purpose              | Alpha      | Example                  |
   +----------------------+------------+--------------------------+
   | Large fill (body)    | 0.08-0.15  | hex_with_alpha(col, 0.1) |
   | Medium fill (accent) | 0.15-0.25  | hex_with_alpha(col, 0.2) |
   | Small fill (detail)  | 0.25-0.35  | hex_with_alpha(bright, 0.3) |
   | Outline stroke       | 1.0        | color = bright           |
   | Secondary stroke     | 1.0        | color = col              |
   | No fill              | ---        | fill = NA                |
   +----------------------+------------+--------------------------+
   

5. Return a flat list() of layers (the renderer iterates and wraps each with glow)

6. Place the function in the appropriate primitives file based on entity type:

   • Skills: domain-grouped across 19 primitives files:
     • primitives.R — bushcraft, compliance, containerization, data-serialization, defensive
     • primitives_2.R — devops, general, git, mcp-integration
     • primitives_3.R — mlops, observability, PM, r-packages, reporting, review, web-dev, esoteric, design
     • Additional primitives_4.R through primitives_19.R for newer domains
   • Agents: viz/R/agent_primitives.R
   • Teams: viz/R/team_primitives.R

Expected: A working R function that returns a list of 2-6 ggplot2 layers.

On failure: If ggforce::geom_circle causes errors, ensure ggforce is installed. If coordinates are off, remember the canvas is 100x100 with (0,0) at bottom-left. Test the function interactively:

source("viz/R/utils.R"); source("viz/R/primitives.R")  # etc.
layers <- glyph_<name>(50, 50, 1.0, "#ff88dd", "#ffa8f0")
p <- ggplot2::ggplot() + ggplot2::coord_fixed(xlim=c(0,100), ylim=c(0,100)) +
     ggplot2::theme_void()
for (l in layers) p <- p + l
print(p)

Step 3: Register — Map Entity to Glyph

Add the entity-to-glyph mapping in the appropriate glyph mapping file.

For skills:

1. Open viz/R/glyphs.R
2. Find the comment section for the target domain (e.g., # -- design (3))
3. Add the entry in alphabetical order within the domain block:

   "skill-id" = "glyph_function_name",
   

4. Update the domain count in the comment if applicable

For agents:

1. Open viz/R/agent_glyphs.R
2. Find the alphabetical position in AGENT_GLYPHS
3. Add the entry:

   "agent-id" = "glyph_function_name",
   

For teams:

1. Open viz/R/team_glyphs.R

2. Find the alphabetical position in TEAM_GLYPHS

3. Add the entry:

   "team-id" = "glyph_function_name",
   

4. Verify no duplicate ID exists in the target list

Expected: The appropriate *_GLYPHS list contains the new mapping.

On failure: If the build later reports "No glyph mapped", double-check that the entity ID exactly matches the one in the manifest and registry.

Step 4: Manifest — Add Icon Entry

Register the icon in the appropriate manifest file.

For skills: viz/data/icon-manifest.json

{
  "skillId": "skill-id",
  "domain": "domain-name",
  "prompt": "<domain basePrompt>, <descriptors>, dark background, vector art",
  "seed": <next_seed>,
  "path": "public/icons/cyberpunk/<domain>/<skill-id>.webp",
  "status": "pending"
}

For agents: viz/data/agent-icon-manifest.json

{
  "agentId": "agent-id",
  "prompt": "<agent-specific descriptors>, dark background, vector art",
  "seed": <next_seed>,
  "path": "public/icons/cyberpunk/agents/<agent-id>.webp",
  "status": "pending"
}

For teams: viz/data/team-icon-manifest.json

{
  "teamId": "team-id",
  "prompt": "<team-specific descriptors>, dark background, vector art",
  "seed": <next_seed>,
  "path": "public/icons/cyberpunk/teams/<team-id>.webp",
  "status": "pending"
}

Expected: Valid JSON with the new entry placed among its type siblings.

On failure: Validate JSON syntax. Common mistakes: trailing comma after last array element, missing quotes.

Step 5: Render — Generate the Icon

Run the icon pipeline to render the new glyph. Always use build.sh as the entry point — it handles platform detection and R binary selection. See render-icon-pipeline for the full flag reference and pipeline architecture.

# From project root — renders all palettes, standard + HD, skips existing icons
bash viz/build.sh --only <domain> --skip-existing          # skills
bash viz/build.sh --type agent --only <id> --skip-existing # agents
bash viz/build.sh --type team --only <id> --skip-existing  # teams

# Dry run first:
bash viz/build.sh --only <domain> --dry-run

build.sh runs the full pipeline (palette → data → manifest → render → terminal glyphs). The non-render steps add ~10 seconds but ensure all data is current.

Output locations:

• Skills: viz/public/icons/<palette>/<domain>/<skill-id>.webp
• Agents: viz/public/icons/<palette>/agents/<agent-id>.webp
• Teams: viz/public/icons/<palette>/teams/<team-id>.webp

Expected: The log shows OK: <entity> (seed=XXXXX, XX.XKB) and the WebP file exists.

On failure:

• "No glyph mapped" — Step 3 mapping is missing or has a typo
• "Unknown domain" — Domain not in get_palette_colors() in palettes.R
• R package errors — Run install.packages(c("ggplot2", "ggforce", "ggfx", "ragg", "magick")) first
• If rendering crashes, test the glyph function interactively (see Step 2 fallback)

Step 6: Verify — Visual Inspection

Check the rendered output meets quality standards.

1. Verify file exists and has reasonable size:

   ls -la viz/public/icons/cyberpunk/<type-path>/<entity-id>.webp
   # Expected: 15-80 KB typical range
   

2. Open the WebP in an image viewer to check:

   • Shape reads clearly at full size (1024x1024)
   • Neon glow is present but not overpowering
   • Background is transparent (no black/white rectangle)
   • No clipping at canvas edges

3. Check at small sizes (the icon renders at ~40-160px in the force graph):

   • Shape remains recognizable
   • Detail doesn't turn to noise
   • Glow doesn't overwhelm the shape

Expected: A clear, recognizable pictogram with even neon glow on transparent background.

On failure:

• Glow too strong: re-render with --glow-sigma 2 (default is 4)
• Glow too weak: re-render with --glow-sigma 8
• Shape unreadable at small sizes: simplify the glyph (fewer layers, bolder strokes, increase .lw(s, base) base value)
• Clipping at edges: reduce shape dimensions or shift center

Step 7: Iterate — Refine if Needed

Make adjustments and re-render.

1. Common adjustments:

   • Bolder strokes: increase .lw(s, base) — try base = 3.0 or 3.5
   • More visible fill: increase alpha from 0.10 to 0.15-0.20
   • Shape proportions: adjust multipliers on s (e.g., 20 * s -> 24 * s)
   • Add/remove detail layers: keep total layers between 2-6 for best results

2. To re-render after changes:

   # Delete the existing icon first, then re-render
   rm viz/public/icons/cyberpunk/<type-path>/<entity-id>.webp
   # Use the appropriate build command from Step 5
   

3. When satisfied, verify the manifest status shows "done" (the build script updates it automatically on success)

Expected: The final icon passes all verification checks from Step 6.

On failure: If after 3+ iterations the glyph still doesn't read well, consider using a completely different visual metaphor (return to Step 1).

Reference

Domain and Entity Color Palettes

All domain colors (for skills) are defined in viz/R/palettes.R (the single source of truth). Agent and team colors are also managed in palettes.R. The cyberpunk palette (hand-tuned neon colors) is in get_cyberpunk_colors(). Viridis-family palettes are auto-generated via viridisLite.

To look up a color:

source("viz/R/palettes.R")
get_palette_colors("cyberpunk")$domains[["design"]]   # skill domain
get_palette_colors("cyberpunk")$agents[["mystic"]]     # agent
get_palette_colors("cyberpunk")$teams[["tending"]]     # team

When adding a new domain, add it to three places in palettes.R:

1. PALETTE_DOMAIN_ORDER (alphabetical)
2. get_cyberpunk_colors() domains list
3. Run bash viz/build.sh to regenerate palettes, data, and manifests

Glyph Function Catalog

See the full catalog of available glyph functions in the primitives source files:

• Skills: viz/R/primitives.R through viz/R/primitives_19.R (domain-grouped)
• Agents: viz/R/agent_primitives.R
• Teams: viz/R/team_primitives.R

Helper Functions

Function	Signature	Purpose
.lw(s, base)	(scale, base=2.5)	Scale-aware line width
.aes(...)	alias for ggplot2::aes	Shorthand aesthetic mapping
hex_with_alpha(hex, alpha)	(string, 0-1)	Add alpha to hex color
brighten_hex(hex, factor)	(string, factor=1.3)	Brighten a hex color
dim_hex(hex, factor)	(string, factor=0.4)	Dim a hex color

Validation Checklist

• Glyph function follows glyph_<name>(cx, cy, s, col, bright) -> list() signature
• All dimensions use * s scaling factor
• Color strategy uses col for fills, bright for outlines, hex_with_alpha() for transparency
• Function placed in correct primitives file for entity type and domain
• Glyph mapping entry added in the appropriate *_glyphs.R file
• Manifest entry added with correct entity ID, path, and "status": "pending"
• Build command runs without error (dry-run first)
• Rendered WebP exists at the expected path
• File size in expected range (15-80 KB)
• Icon reads clearly at both 1024px and ~40px display sizes
• Transparent background (no solid rectangle behind the glyph)
• Manifest status updated to "done" after successful render

Common Pitfalls

• Forgetting * s: Hard-coded pixel values break when scale changes. Always multiply by s.
• Canvas origin confusion: (0,0) is bottom-left, not top-left. Higher y values move UP.
• Double glow: The renderer already applies ggfx::with_outer_glow() to every layer. Do NOT add glow inside the glyph function.
• Too many layers: Each layer gets individual glow wrapping. More than 8 layers makes rendering slow and visually noisy.
• Mismatched IDs: The entity ID in the glyph mapping, manifest, and registry must all match exactly.
• JSON trailing commas: The manifest is strict JSON. No trailing comma after the last array element.
• Missing domain color: If the domain isn't in get_cyberpunk_colors() in palettes.R, rendering will error. Add the color first, then regenerate.
• Wrong primitives file: Skills go in domain-grouped primitives*.R, agents in agent_primitives.R, teams in team_primitives.R.
