Signal Geometry

Signal Geometry is an Agent Skill for turning one concept into a sparse abstract illustration or poster. It uses precise geometry, quiet matte fields, restrained contrast, and one legible spatial event.

Install

Using npm:

npx skills add CaliCastle/skills --skill signal-geometry

Using pnpm:

pnpm dlx skills add CaliCastle/skills --skill signal-geometry

Use

Invoke the skill explicitly with $signal-geometry:

Use $signal-geometry to create a dark 4:5 poster about a weak signal becoming stable through repeated filtering. No text.

For a prompt without rendering:

Use $signal-geometry in prompt-only mode for an ultrawide illustration about two systems finding equilibrium.

Output

Rendered work includes the accepted image, its exact final prompt, and the complete composition recipe. Prompt-only mode returns the prompt and recipe without generating an image.

Requirements

• Prompt-only mode works without image tools.
• Rendered mode requires image generation and image inspection capabilities.
• The Codex integration is explicit-only by design, so invoke $signal-geometry by name.

Chalk Logic

Chalk Logic is an Agent Skill for turning one concept into a quiet, wordless white-chalk illustration on a desaturated green board. It supports explanatory systems, natural processes, observed objects, and sparse editorial scenes without drifting into classroom clutter or polished digital graphics.

Install

Using pnpm:

pnpm dlx skills add CaliCastle/skills --skill chalk-logic

Using npm:

npx skills add CaliCastle/skills --skill chalk-logic

Use

Invoke the skill with $chalk-logic:

Use $chalk-logic to create a quiet 16:9 wordless illustration about a heavy thought becoming easier to carry.

For a prompt without rendering:

Use $chalk-logic in prompt-only mode for a portrait illustration explaining how a key opens a lock. No labels.

Output

Rendered work includes the inspected image, its exact prompt sequence, the complete composition recipe, and QA status. Prompt-only mode returns the compiled prompt and recipe without generating an image.

Requirements

• Prompt-only mode works without image tools.
• Rendered mode requires image generation and image inspection capabilities.
• Image-free conversations route generation and inspection through an isolated worker and return file links only.
