Skills.
Give your AI a better way to work.
A skill is a set of written instructions that teaches an AI how to do one job the way it should be done: review a pull request, plan a migration, write the release notes.

a-stated-rule-needs-annotated-exceptionsSkillMedia
A design rule with legitimate exceptions survives only if every exception carries its reason at the call site and the rule itself is greppable — otherwise nothing distinguishes an exception from a violation and the rule silently rots. Covers where the rule statement goes, where the reasons go, scopi

ambient-tone-layer-behind-flat-pagesSkillMedia
A reusable top-glow layer that gives pages with no imagery of their own the same tinted ground the image-backed screens get — emitted as the first sibling of a navigation destination's content, with no wrapper, because destinations already stack. Covers why a null tone must collapse the gradient int

artwork-palette-themingSkillMedia
Drive a screen's colours from its artwork — which extracted swatch to use for an accent versus for a large page background, luminance-adaptive darkening so overlaid text stays readable on any image, the hex parsing helper this needs, and what to do when extraction returns nothing or there is no artw

audio-fade-separate-gain-lineSkillMedia
Implement a programmatic audio fade — a sleep timer, an alarm ramp, a duck — on a gain line of its own instead of the user's volume, and restore that gain from the player's own completion path. Use when a fade drags the volume slider down in the UI, when the app comes back permanently silent with a

audio-focus-multiplayerSkillMedia
Hold Android audio focus once at app level when several player instances are alive at the same time — dual-player crossfade, precached players — and keep focus-driven ducking off whatever gain line a fade already owns. Use when background playback dies between tracks, autoplay stalls after the first

compose-capture-to-share-imageSkillMedia
Render a composable off-screen into an ImageBitmap so a button can save or share it as a picture — a capture primitive ported into common code rather than pulled in as a platform-only dependency, a max-width ceiling standing in for a fixed output size, artwork that has to already be resolved before

compose-desktop-video-no-swingpanelSkillMedia
Rendering video frames from a native media engine in Compose Desktop without embedding a heavyweight AWT panel — publish finished frames as immutable snapshots on a StateFlow and draw them with a plain Image, convert off the UI thread, match the engine's pixel byte order, and let the engine decide t

crossfade-exclusion-heuristicsSkillMedia
Decide when a crossfade must NOT run — the item plays as video, the item is too short for the fade, or two consecutive items belong to the same album — and encode each rule so it survives shuffle, an auto-length fade and a queue that keeps growing. Use when a fade cuts a song short, a video jumps to

delta-absent-not-infiniteSkillMedia
Render a change figure against an empty or zero baseline as nothing at all — never "+100%", never an infinity, never a saturated integer — and guard the two spans being compared as well as the divisor. Use when a new user's first period shows a huge increase against every figure, when "+0%" appears

deterministic-title-placeholder-painterSkillMedia
Give items with no artwork a cover of their own by hashing the title into a stable gradient and packaging it, plus measured text and a badge, as a custom Painter you can hand straight to an image loader's placeholder, error and fallback slots — covering what makes the hash actually deterministic, me

embed-media-engine-desktopSkillMedia
Embedding a native C media engine in a JVM desktop app — one handle per media item, a dedicated event-pump thread, pinning the output driver and creating the render context in the right order, confining every property write to the thread that also releases handles, feature-detecting optional engine

forwarding-player-hot-swapSkillMedia
Swap the underlying player beneath a `ForwardingPlayer` at runtime while the media session and the UI keep one stable reference — re-attaching listeners and the video output, and answering the playlist questions a one-item timeline cannot. Use when next/previous buttons vanish from the system notifi

fullscreen-video-gesture-overlaySkillMedia
The gesture and chrome layers of a fullscreen video screen — tap anywhere to toggle the controls, double-tap either half to seek, an auto-hide timer that every interaction postpones, and a picture-in-picture (PiP) guard that removes both layers. Use when single taps work on only half the screen, whe

Retry a record's image at a variant the source guarantees when the high-resolution one is missing, by holding the URL in composition state and swapping it once in onError.

layered-video-backdrop-pagerSkillMedia
Building a swipeable now-playing page whose layers — a colour backdrop, a full-bleed looping video or image, and a centred square cover — all belong to one pager, with per-page colours taken from the bitmap that page actually painted and a scrim spanning the whole page. Use when a swipe makes the ba

marker-interface-nested-enum-polymorphismSkillMedia
Render one heterogeneous list with one composable by tagging unrelated classes with an empty interface, plus a nested enum each implementor answers where the renderer has to branch. Covers when a tag beats a sealed hierarchy, the exhaustiveness you give up in exchange, and the ways an item silently

media3-custom-audio-processorSkillMedia
Write a custom audio processor for a Media3/ExoPlayer audio pipeline — a filter, a fade, a gain stage — that is toggled at runtime and shared across several concurrent players.

one-setting-two-backendsSkillMedia
Make one stored value mean the same thing on two unrelated audio backends by defining the band centres, the width and the range once, verifying both against a reference implementation instead of by ear, and declining the platform's built-in effect whose parameters vary per device. Use when a tone or

one-snapshot-per-period-not-many-flowsSkillMedia
Return a whole period's figures as one immutable snapshot from a single suspend call, rather than as a dozen independent flows the screen has to line up — a screen comparing two spans needs each span coherent, and separate emissions let a count from this period render beside a total from the last.

per-track-loudness-normalizationSkillMedia
Apply per-track loudness normalisation with the platform's loudness enhancer when each track gets its own player — re-creating the effect per track because it stays attached to one audio session, skipping it while a remote-playback session is active, and clamping the gain that comes from metadata.

What is a skill?
A skill is plain text, usually a SKILL.md file and the scripts it refers to, written for an AI rather than for a person. It carries the steps, the house rules and the examples a good answer needs, so you stop pasting the same briefing into every new chat.
53,585 of the 54,017 skills listed here can be served through ahel today, and they come from public repositories. Each one has its own page with the instructions themselves on it, so you can read what a skill will tell your AI to do before you install it.
Install one and every AI you use gets it
Installing a skill adds it to your gateway and turns it on in the same step. Claude Code surfaces it as a slash command; any client can read the full instructions with the skill_read tool.
Nothing is copied into a project folder. The instructions are served from your account, so the same skill is there in every AI you connect, and turning it off removes it from all of them at once.
