Vitor PamplonaandClaude Opus 5.5 395af4dc9c chore(skills): consolidate 33 skills into 14, verified against the tree

The 33 descriptions (~16k chars, ~19k with paths) overran Codex's skill-list
budget (2% of the context window, or 8,000 chars when unknown), and a review
found most bodies stale: paths from before the commons/commonsUI moves, the
deleted legacy desktop app, a callback signer API that no longer exists, and
example APIs that were never in the tree.

Kept, rewritten and checked against the code (every path, class and command):
account-state (+feeds), amy-expert, android-expert, auth-signers,
compose-expert (+API style, Navigation 3 back stacks), desktop-expert
(+run/package), event-store-semantics (+NIP-50 search), find-missing-
translations, kotlin-coroutines (+structured concurrency, flow modeling),
kotlin-multiplatform (+Gradle, composable extraction), ngit-pr,
nip85-trusted-assertions, nostr-expert (+NIP lookup, generated NIP catalog),
relay-client.

Dropped: textbook Compose/Kotlin technique skills, kotlin-expert,
kotlin-types-value-class, gradle-expert, quartz-integration (external-facing;
see the Quartz docs commit), find-non-lambda-logs (audit finished; the rule is
now in AGENTS.md Kotlin Style), and the /nip, /desktop-run, /extract commands.
The skill list is now ~4k chars. Also drops .claude/core-skills-plan.md
(stale history) and repoints SearchableEvent's KDoc to event-store-semantics.

Icons are fonts, not ImageVectors: see AGENTS.md "Icons" (Amethyst's icons/*.kt compile into amethyst_icons.ttf and draw through AmethystIconGlyph; Material icons are MaterialSymbols from a subset font). Robohash is the one generated vector asset.

Files

Under commonsUI/src/commonMain/kotlin/com/vitorpamplona/amethyst/commons/robohash/:

RobohashAssembler.kt: class RobohashAssembler with build(msg, isLightTheme): ImageVector, plus inline fun roboBuilder(name, autoMirror, block) (an ImageVector.Builder on the shared viewport).
CachedRobohash.kt: object CachedRobohash, an LruCache of 100 vectors. get(msg, isLightTheme) builds or hits, cached(...) only hits, trimToSize(maxItems). The whole cache is evicted when the theme flips.
parts/: 50 part files, 10 variants each of Accessory*, Body*, Eyes*, Face*, Mouth* (for example Face0C3po.kt). Each adds layered paths to the builder with a seed-derived foreground color and fixed black strokes / alpha shading.

Behaviour worth knowing

The seed is a hex pubkey. Hex of at least 22 chars is decoded directly (the assembler reads bytes 0..10). Anything shorter or non-hex is SHA-256'd first, and a Log.w is emitted. A blank seed falls back to an all-zero key.
The color range depends on the theme: light theme uses bright channels (150+), dark uses dim ones (50-100). Always pass MaterialTheme.colorScheme.isLight.

Composables

In commonsUI/.../commons/ui/components/:

RobohashImage(robot, modifier, contentDescription, loadRobohash) and an overload with alignment, contentScale, colorFilter. When loadRobohash is false it draws the MaterialSymbols.Face placeholder instead.
RobohashFallbackAsyncImage(robot, model, ...) (RobohashAsyncImage.kt): loads the profile picture model through Coil and falls back to the robohash. RobohashAsyncImage there is the robohash-only variant. For a user's avatar prefer UserAvatar(userHex, pictureUrl, size, ...) (UserAvatar.kt), which reads the display settings and draws through a platform expect fun AvatarImage.

Benchmarks: benchmark/src/androidTest/java/com/vitorpamplona/amethyst/benchmark/RobohashBenchmark.kt and RobohashPartsBenchmark.kt.
