* feat: add ascii-city-engine skill New skill teaching portable first-person colored-ASCII city engines and small GIS-derived city packs: - references/engine-architecture.md: terrain height function, ground- attached pedestrian physics (feet_z=terrain(x,y), step/slope limits, building-footprint collision with wall sliding), fisheye-corrected raycast-to-ASCII pipeline, glyph density ladder, deterministic color. - references/city-provider-contract.md: manifest + world-tile semantics, single-height-per-column v1 limit, reserved surface-graph extension. - references/gis-ingestion.md: USGS 3DEP/OSM/municipal source classes, meter-CRS reprojection, unit checks, 3.2 m/floor height fallback, provenance/confidence recording. - references/raleigh-poc.md: numeric downtown bbox, named sources with URLs, acquire/convert/validate commands, 4 human acceptance checks. - templates/: city-pack-manifest + world JSON Schemas. - scripts/validate-city-pack.py: pure-stdlib offline validator (78 rules). - assets/raleigh-downtown-sample/: committed coarse pack (30 real OSM buildings, 25 road/path surfaces, 78x64 10 m terrain) <= 64K. - assets/ascii-city-engine.html: dependency-free Canvas 2D engine. - evals/evals.json: 6 schema-valid cases incl. runtime-specificity and large-GIS-commit refusal boundaries. - README.md catalog entry. AI-assisted contribution (Hermes Agent, spec-driven-development pipeline). * chore: regenerate claude marketplace for ascii-city-engine * chore: regenerate codex plugin and llms.txt for ascii-city-engine * fix(ascii-city-engine): address droid-review findings on PR #321 1. [P2] Engine scaffold now reads manifest.json for spawn + first tile instead of hardcoding (315,385) — restores pack interchangeability. 2. [P2] Validator all_points() guards isinstance(dict) so structurally invalid tiles report FAIL instead of crashing with AttributeError. 3. [P2] raleigh-poc acceptance walk: correct duration/elevation math (~25s/~100m to ~100.9m at (315,505); ~95s to north edge ~103.0m). 4. [P3] known-limitations: match committed data — 5/30 explicit OSM height (0.88), 25 floor-estimated (0.72), not ~26%/0.55/0.35. 5. [P3] bbox: document tangent-plane 632x779m vs normalized 630x770m working extent instead of asserting 630x770 as the conversion result. 6. [P3][security] cap polygon vertices (2000), elevation cells (4M), feature count to prevent O(n^2) CPU-exhaustion on crafted packs. Verified: sample pack 79/79 PASS exit 0; broken fixture exit 1; droid AttributeError repro now FAILs cleanly; 5000-vertex footprint rejected in 58ms; node --check OK; validate-skills.rb 154 green; blocklist clean.
