dsh-night-flight-companion · Night Flight Companion

A dark skin for DeepSeek Harness (dsh): deep night blue, moonlight cyan and a touch of warm cream, with a full night-flight banner on the new-session page.

What it changes

Surface	Content
Palette	A full set of --dsw-alias-* / --dsw-specific-* semantic tokens on the dark base, with every border a 1px line tinted moonlight cyan
New session	The banner takes all the height above the composer (a 16px radius, a moonlight-cyan border, a deep shadow), the composer sits separately below, and an identity badge occupies the top-left corner
Brand slots	The sidebar and new-session marks are a pure-CSS moon ring (a bright lunar core, a blue ring, a night ground and a cyan glow), with the subtitle Night Flight Companion
Status dock	Always present on the chat page: a reduced banner plus six kinds of real state, collapsible (the choice is remembered)

Only one warm colour

The whole skin rests on deep night blue and moonlight cyan, and its only warm colour is moonlight cream #ded0ae. The prototype uses it solely at the end of the energy-bar gradient (linear-gradient(90deg,#5f88da,#7bd8ff,#ded0ae)), like the lamp wrapped in night in the picture — so here too it gets exactly one place: the end of the context-usage bar. Spread wider it stops being a touch of warmth.

Red is toned down too: the last thing this skin should contain is anything that glares, so the error colour is a low-saturation #e5798a.

The layout follows the prototype

The prototype states the rule itself: New Session uses the whole banner as the hero visual with the composer separately below, while keeping the full Harness workspace. Its #home is likewise column plus .hero { flex: 1 } with a separate .composer below. So the banner does not sit over the composer, and carries no copy beyond the identity badge in its top-left corner.

What the status dock shows

Card	Fields	Source
Waiting on you	Tools awaiting approval, questions awaiting an answer	ConversationSnapshot.pending. Appears only when something is genuinely waiting
Current Session	State, elapsed turn time, current tool duration, inbox, model	running / turnTimings / runningCalls / queue; the model comes from the latest assistant message's provenance.model
Context	Occupancy %, token load, and the System / tool-schema / conversation composition bar	The contextPressure and contextBreakdown projections
Permission	The active permission and sandbox mode	The permissions projection
Usage	Input / output / cache hits / time spent / turns	The tokenUsage and sessionStats projections
Plan	Todo progress	The todos projection (the card is absent when there is no list)
Flight log	Tool name · real duration · outcome	Trajectory tool-result nodes (duration = time - callTime) plus the snapshot's runningCalls. Appears only once a call has happened
Context injections	The source and form of each injection	Trajectory context nodes (provenance.label / form)
Folded away	Compaction count, items and tokens folded	Trajectory compaction nodes. Absent when nothing was compacted

⚠️ A tool duration may be absent: it can only be computed while the matching tool/call is still inside the session window. Older calls that scrolled past report only name and outcome — better blank than an invented figure.

⚠️ Composition is not a total: the three contextBreakdown figures are fixed-density estimates and do not add up to the token load.

Four things deliberately not done

These are all hardcoded decoration in the prototype with no matching projection in the harness, so none are built — decoration is fine; fake state is not:

• the four ONLINE rows under Harness Systems in the right column
• the four Flight Modes cards in the right column
• the 85% and 100% under Moonlight Energy in the right column
• the "☾ MOONLIGHT ONLINE" badge in the cover's top-right corner

No host copy is replaced either: this prototype gives no agent-copy specification, and inventing lines without a basis is embellishment.

One implementation detail

The dock's thumbnail crops with background-position: left center rather than centred — the banner's subject (the three figures in flight and the umbrella) sits in the left third of the image, with a wide moonlit valley to the right, so a centred crop would yield nothing but night.

Install

Skin market (recommended): search for "Night Flight", install, then restart dsh.

Manual install (during development):

npm install && npm run build
DST=~/.dsh/profiles/web/node_modules/dsh-night-flight-companion
mkdir -p "$DST" && cp -R lib cordis.patch.yml skin.json package.json README.md "$DST/"
# then add dsh-night-flight-companion to the profile package.json's dependencies and dsh.profile.bundles

🔴 The side effect of autoApply

Installing switches to this skin by default. The harness does not persist third-party theme ids, and the built-in Settings → Appearance offers only three cells — light / dark / follow system — so switching manually requires the skin market's own panel. The cost is that it reapplies on every refresh: switching away lasts only for that session. To change permanently, set autoApply to false or uninstall.

Version requirements

Requires dsh 0.1.1-rc.2 or newer (the brand-slot takeover relies on slot priority shadowing; older versions simply fall back to the official brand mark, with the palette and banner working as usual).

Assets

The banner is a 1672×941 illustration compressed to webp (q92, 231 KB) and inlined into the bundle rather than linked from an image host. How it is generated and its resolution ceiling are documented at the top of src/client/cover.generated.ts.

Development

npm run check   # tsc --noEmit
npm run build   # produces lib/index.js (host half) and lib/client.js (browser half)

lib/ must be committed: skins install via github:owner/repo, which installs the build output from the repository.
