viewer-evaluation
philliphoff/EncDotNet.S100
Procedure for running an independent, automated evaluation loop
against the EncDotNet.S100 Avalonia viewer using its CLI flags and
embedded MCP server. Lets an agent launch the viewer headlessly,
load datasets, drive viewport / palette / display-category / time-step
/ own-ship, capture screenshots, await render-idle, and read render
stats — then iterate. USE FOR: visually verifying a rendering or
portrayal change; designing or reproducing integration/regression
scenarios; measuring load/render performance; capturing reference
images; deriving test fixtures from real datasets; any "does it
actually look/behave right in the viewer?" question — INCLUDING from
renderer (Renderers.Mapsui / Renderers.Skia), Core pipeline, or
Datasets.SXXX work, not only when editing the Viewer project.
DO NOT USE FOR: pure library logic unit tests (write xunit directly),
viewer XAML/localization conventions (see viewer.instructions.md),
or the MCP tool catalogue reference (see docs/mcp-server.md).
chart-cartography
philliphoff/EncDotNet.S100
Cross-cutting cartography and chart-rendering domain expertise for
electronic navigational displays — the principles of how marine
charts are composed, layered, generalized, coloured, projected, and
made performant. Spec- and renderer-agnostic: it explains the
*why/what* of good chart rendering and how those principles manifest
in this codebase, then defers to the per-spec skills for product
semantics and to the renderer READMEs for implementation. USE FOR:
layer/draw-order and display-priority decisions; scale-dependent
generalization, declutter, SCAMIN/scale-band culling; label/text
placement and deconfliction; day/dusk/night palette and contrast
design; CRS/projection choices and distortion/antimeridian/pole
pitfalls; rendering-performance strategy (geometry simplification,
path/snapshot caching, tiling, vertex-bound cost reasoning); reviewing
a rendering change for cartographic correctness across products.
DO NOT USE FOR: a specific product's encoding/attribute/portrayal
rules (use the sXXX skill); Mapsui

Expert knowledge of IALA S-201 Aids to Navigation Information
Product Specification (Edition 2.0.0, May 2025; aligned with
S-100 Ed 5.2.0). Covers GML encoding (S-100 Part 10b) on the
S-100 GML 5.0 profile, the S-201 application schema (62 feature
types — buoys, beacons, lights, AIS aids, structures,
equipment, aggregations), the 4 information types
(AtoNFixingMethod, AtonStatusInformation, PositioningInformation,
