development is a skill-library plugin that bundles three workflow-oriented skills agents can invoke during everyday repo work.

Skills

cross-examine

Triggers when the user wants to stress-test a plan, get grilled on a design, or says “grill me”. Walks down each branch of the design tree, resolving dependencies between decisions one at a time and asking questions in sequence.

data-viz-renderer

Generates self-contained HTML / SVG infographics from JSON data. Four supported types:
  1. Stats Cards — KPI big numbers, trend arrows, icons
  2. Comparison Chart — Grouped bar chart with multiple series
  3. Flow Diagram — Step-by-step process with numbering, icons, connecting arrows
  4. Dashboard — Mixed layout with stat cards, bar chart, donut chart, and flow
Output is fully self-contained HTML (CSS / SVG inline, zero external dependencies). 8 color palettes and 24 built-in SVG icons.

skill-evaluator

Evaluates a local skill against a 5-dimension rubric, produces a structured report, and recommends next steps. Triggers on phrases like “evaluate this skill”, “analyze this plugin”, “why did this score that way”, “benchmark this skill”.
