🚀 Updates v0.10.26: Architecture Decomposition & Repository Sanitization (#235, #238, #239)
- Architecture & Modular Decomposition (#239): All server modules in
lib/ now strictly meet the <= 600 line threshold: extracted lib/tools/generation-pack.js (74 lines, reduces lib/tools/generation.js to 547 lines), lib/history.js (93 lines), and lib/attachment-helper.js (82 lines, reduces lib/index.js to 557 lines). Client codebase modularized across 15 sub-modules in src/client/* (all <= 337 lines).
- Repository Sanitization (#235): Internal agent workflow files (
AGENTS.md, index.md) fully untracked from Git and excluded via .gitignore and .gitattributes.
- Theme Parity Completed (#238): Full verification and closure of zero-standalone-color rule across all Web UI surfaces with native
--dsw-alias-* variables and color-mix(...) state tints.
- Package Integrity: Added canonical
README.ru.md and README.zh.md to npm package files allowlist.
🚀 Updates v0.10.25: Theme Color Parity, Responsive Mockups, Patterns & Spritesheets (#173, #177, #178, #238)
- 100% Theme Color Parity (#238): Completely replaced all hardcoded
rgba(...) and hex color literals in the Web UI (src/client/10-css.js, src/client/80-gallery.js) with native DSH theme variables (--dsw-alias-*) and dynamic color-mix(...). Badges, alerts, and modal overlays automatically adapt to light and dark themes with zero hardcoded values.
- Responsive Multi-Device Mockup Generator (
generate_responsive_mockups, #173): Single product prompt generates coherent Mobile (9:16), Tablet (3:4), and Desktop (16:9) viewports in parallel via asyncPool concurrency limit (3). Interactive toolview with tabbed preview navigation.
- Seamless Pattern Generator (
generate_seamless_pattern, #178): Automated tileable background texture generation with periodic boundary condition checks and CSS tiling preview.
- 2D Spritesheet Generator (
generate_spritesheet, #177): Produces horizontal animation strips with CSS keyframe generator and multi-frame SVG previews for 2D game dev and web UI animations.
- Client Modular Source Build (#244): Decomposed monolithic
lib/client.js into 15 structured fragments under src/client/* with automated build runner scripts/build-client.mjs. Preflight check FAIL=0, 179/179 automated tests passing.
🚀 Updates v0.10.24: Quality Block — Publication Boundary, Settings Status, Theme Colors & Module Split (#235–#242)
- Publication Boundary: Added
.gitattributes with export-ignore for AGENTS.md, index.md, docs/, and .gitea/ so GitHub source archives and git archive no longer ship internal workflow files.
- Settings Status Fallback: Corrected provider/config status handling in the Settings Card so partial/unknown states no longer show a false “unavailable”.
- Design-System Alignment: Renamed residual
fal- CSS class prefixes to the ig- system and bound colors to DSH theme variables via var(--dsw-alias-*, <fallback>).
- Sensitive File Hardening: History, cache meta/data, and spend-meter writes now enforce
0600 permissions after write.
- Dead Code Removal & Module Split: Removed unused
listCuratedStyles; split oversized server modules — providers.js utils extracted to provider-utils.js, processing.js into processing-basic.js + processing-advanced.js. Client file split is tracked separately (#244).
🚀 Updates v0.10.23: In-App Auto-Updater, Settings Synchronization, Active Probes & Language Purity (#232)
- One-Click In-App Auto-Updater: Direct 1-click update support inside the plugin Settings Card (
UpdaterSection) backed by /api/dsh-image-gen/update. Fetches the npm registry for release manifests, verifies semver differences, and securely triggers dsh plugin add @goodandready/dsh-image-gen@latest restricted to loopback and private LAN connections.
- 1:1 Settings Synchronization: Fully synchronized host
Config schema in lib/index.js with client UI fields (lib/client.js), exposing autoEnhancePrompt and defaultStylePreset under the ✨ Enhancer tab.
- Active Diagnostic Probes: Added real HTTP network probes in
testProviderConnection for Replicate (/v1/models), Google Gemini (/v1beta/models), and ByteDance Seedream with timeout protection and live roundtrip latency tracking.
- Strict Multi-Language Compliance: Pure standard
en and zh localization bundles embedded in core package; modularized Russian language support via goodandready/dsh-russian-lang per DSH plugin guidelines. Exactly 0 Cyrillic characters in product code (lib/).
- WAI-ARIA Accessibility Hardening: Enhanced tab navigation and input form validation with
role="tablist", role="tab", aria-selected, aria-controls, role="tabpanel", aria-describedby, and role="alert".
🚀 Updates v0.10.22: Referential Stability & React Error #185 Infinite Loop Fix (#230)
- Settings Card Referential Stability: Resolved React Error #185 (
Maximum update depth exceeded) in FalSettingsCardController and CardForm.prototype.bind. Store snapshots are referentially cached during render cycles (Object.is(prev, next) === true), completely preventing infinite re-render loops in React 18 / useSyncExternalStore.
- Deep DSH Store Integration: Added seamless runtime integration with
@deepseek-ai/dsh-client-store (runtime.createSnapshotStore) paired with a robust standalone snapshot caching fallback.
- Automated Regression Test Suite: Added dedicated referential identity test in
test/client-syntax.test.mjs verifying snapshot immutability across repeated reads, single-notification publish triggers, and clean listener lifecycle.
🚀 Updates v0.10.21: Variations Workbench, Smart Aspect Ratio Crop & Brand Asset Pack (#228)
- Variations & Style Remix Workbench: Interactive visual drawer embedded directly in
FalImageCard and Gallery. Fine-tune variations with a continuous creativity / denoising strength slider (0.05 to 0.95), preset quick buttons ("Subtle 0.25", "Creative 0.65"), and prompt modifier guidance.
- Intelligent Aspect-Ratio Canvas Cropper & Resizer (
smart_crop_image): Instant lossless aspect ratio framing for social and responsive surfaces (1:1, 16:9, 9:16, 4:3, 3:2, 2:3) supporting focal heuristics (auto_focus, center, rule_of_thirds, letterbox) via zero-dependency pure Node.js SVG vector raster wrapper.
- Project Asset Pack & Social Card Exporter (
export_asset_pack): Production-ready automated brand asset generation producing SVG favicons, PWA application icon suite (icon-192.svg, icon-512.svg), manifest.webmanifest, high-resolution OpenGraph social banner preview (og-card.svg at 1200×630), and an asset manifest catalog (catalog.json).
- Dedicated Toolviews for 12 Visual Tools: Direct interactive action buttons and visual renderers in conversation sessions for all generation, editing, inpainting, remix, crop, export, and collage tools.
- Strict Localization Standard: Complete
zh and en UI dictionary integration; Russian locale registered via goodandready/dsh-russian-lang.
🚀 Updates v0.10.19: Sidebar Gallery, Diagnostics & Style Engine (#224)
- Native Sidebar Gallery & History Drawer: Integrated directly into DSH's native right sidebar pane (
sidebarRightTabs and sidebar.right.pane.tab), betterSidebar, and a quick-access utility chip in the conversation header (conversation.session.header.utilities). Browse past generations, inspect metadata, copy prompts, and export links without cluttering the chat.
- Interactive Provider Diagnostics: Real-time "Test Connection" button in the Settings Card under the Providers tab. Ping Fal.ai, ComfyUI, Automatic1111, or Custom OpenAI-compatible endpoints with live roundtrip latency tracking and status badges (Ready, High Latency, Unreachable).
- Curated Style Presets & Smart Prompt Polisher: Built-in artistic engine with 10 curated styles (
cinematic, photorealistic, anime, minimalist_vector, isometric_3d, analog_film, cyberpunk, pixel_art, oil_painting, claymation), optional autoEnhancePrompt setting, and style_preset tool parameter.
- Collage & Comparison Grid Assembler (
assemble_image_grid): Stitch 2 to 4 images into clean side-by-side, 2x2 grid, or vertical collage comparison graphics via pure Node.js SVG raster rendering, zero heavy external binaries (< 250 KiB package size).
- Color Palette-Constrained Generation: Pass
palette_colors (hex color array) into generate_image to mathematically bias the prompt and negative prompt toward your exact brand color palette with automated WCAG contrast validation.
- Inpainting & Mask Support in
edit_image: Added mask_image (alias for mask) and fine-grained strength (0.0 to 1.0) control for localized inpainting in Fal.ai and custom gateways.
- Full Chinese & English UI Dictionaries: Complete
zh and en localization coverage in Web UI, with Russian translation registered via goodandready/dsh-russian-lang.
🚀 Updates v0.10.18: Speed Acceleration & Quality Hardening (#222)
- Parallel Batch & Pack Generation: Multi-variation requests (
count > 1, prompts array) and generate_image_pack multi-ratio workflows now execute concurrently with a concurrency limit (concurrency: 3) via asyncPool, reducing generation wait times by up to 3x.
- Zero-Delay Initial Polling: Eliminated artificial initial delay in
pollStatus and queue runners (Fal.ai, ComfyUI), inspecting generation status immediately on first attempt and shaving 1–1.5s off fast generative workflows.
- Sub-Millisecond L1 In-Memory Cache: Built-in 32-entry in-memory LRU cache atop disk cache L2 provides instantaneous (< 0.1 ms) cache hits without synchronous disk I/O.
- Fast-Fail Quota Detection: Added classification for HTTP 402 (Payment Required) and exhausted account quota/credits in
isFatalClientError, enabling immediate, clean fallback transitions without fruitless retry loops.
- Expanded Test Suite: Added
test/batch5-speed-quality.test.mjs, bringing total test coverage to 136 automated unit tests (100% pass).
🚀 Updates v0.10.17: Modular Tool Lifecycle (#216, #217)
- Tool modules extracted from
apply(): host lifecycle in lib/index.js is now a thin cordis entry (~650 lines). Tool definitions live in lib/tools/{generation,processing,editing,inspect,frontend}.js behind lib/register-tools.js.
- Per-tool labeled
ctx.effect: each of the 15 tools registers in its own effect (dsh-image-gen: tool <name>) for clean unload/reload disposal.
- Project meta:
AGENTS.md and index.md document architecture, constraints, and the test matrix (internal workflow files — not shipped in the npm package).
- Design contract:
docs/design/DESIGN.md no longer advertises the removed HistoryGallery UI (#203).
- Regression lock:
test/lifecycle-structure.test.mjs asserts modular layout, labeled effects, and meta files. Suite: 132 unit tests.
⚡ Overview
@goodandready/dsh-image-gen is a premier graphic generation and visual processing suite for DeepSeek Harness.

🚀 Updates in v0.10.4: Cordis Lifecycle, Full Settings GUI, and i18n
- Cordis Lifecycle (#136): wrapped all 7 tool registrations in
ctx.effect for proper disposal on reload.
- Settings GUI Completeness (#137): exposed fields for Replicate, SeaDream, Gemini, Local ComfyUI/A1111, style presets, and LLM enhancer.
- Package Manifest (#138): declared kernel
peerDependencies (host-webserver, settings, llm, system-prompt).
- React Cleanup (#139): removed dead state hooks from
FalImageCard.
- Complete Localization (#140): eliminated hardcoded strings, wiring comprehensive dictionaries for en, ru, and zh.
🚀 What's New in v0.10.7 (#197)
- Robust Error Formatting: completely prevents
[object Object] from appearing in provider refusal chains, extracting deep .message, .detail, and .error objects cleanly.
- Deduplicated Provider Prefixes: eliminates redundant
codex: codex: ... prefixes.
- FAL Credential Aliasing: seamless fallback between
FAL_API_KEY and FAL_KEY in credentials and environment.
- Subscription Aspect Ratio Mapping: maps aspect ratios (
16:9, 3:2, 9:16, 2:3) to appropriate subscription dimensions (1536x1024 / 1024x1536) instead of falling back to default square 1024x1024.
🚀 What's New in v0.10.16
- Safe Attachment Service Fallback (#214): Added graceful fallback handling in
saveAttachmentSafe across all 8 visual tools (generate_image, variations, remove_background, upscale_image, blend_images, etc.). When running in headless CLI mode or when the attachment store is unavailable, outputs are safely written to disk with full file paths and data references rather than crashing tool execution.
- HTTP Image Endpoint Strict Validation: Hardened
/dsh-image-gen/image route against malformed or NaN parameters (b, w, h), cleanly responding with HTTP 400 or 404 without leaking internal system traces.
- ComfyUI Node Error Extraction: Integrated
extractComfyNodeErrors to parse node execution errors from /history/{pid} status responses, immediately reporting root-cause node diagnostics rather than timing out.
- Custom Provider Error Normalization: Standardized gateway error extracts through
formatErrorMessage, eliminating raw JSON or [object Object] artifacts on 4xx/5xx API responses.
- Cache & History Consistency: Ensured content-addressed disk cache hits synchronize seamlessly with generation history and sidecar metadata.
- Test Suite Expansion: Added
test/batch4-hardening.test.mjs, expanding test coverage to 128 automated unit tests (100% pass).
🚀 What's New in v0.10.15
- Loop Guard Zero-Limit Bypass (#212): Fixed an edge case where setting
loopGuardLimit: 0 (configured to disable protection) enforced a limit of 1 due to Math.max(1, limit). Setting limit to 0 now properly bypasses loop checks.
- Security Hardening (Token Masking): Added automatic pattern masking for Replicate API tokens (
r8_...) and Google Gemini API keys (AIza...) in sanitizeErrorAndLogs.
- Cache Resilience: Isolated LRU touch updates in
getCachedGeneration so that metadata write contention does not discard valid image bytes on cache hits.
- Defensive File Safety: Added explicit file existence, empty file (0 bytes), and 50 MB maximum size cap checks in
resolveConversationImage preventing OOM crashes on huge files.
- Vectorize Image Attachment & Toolview Preview:
vectorize_image now registers the SVG in ctx.attachments and provides url, enabling interactive preview in tool.call.toolview.
- SVG Markup Validation: Added strict validation in
optimizeSvgContent rejecting non-SVG strings with descriptive errors.
- Cost Meter Safety: Hardened
assertBudgetAvailable to handle string/undefined/NaN values safely.
- Expanded Test Suite: Added
test/batch3-quality.test.mjs expanding suite to 126 automated tests (100% pass).
🚀 What's New in v0.10.14
- dsh-clinebot Unified Visual Overhaul (#210): Redesigned client settings card following the high-end
dsh-clinebot unified design system. Added top quick stats row (.ig-grid-4, .ig-stat-box) showing active provider, default specs, safety/loop guard, and daily budget/cache status. Integrated status badges (.ig-badge-ok/warn/bad).
- 5 Categorized Settings Tabs: Settings fields organized into intuitive tabs: ⚙️ General, 🔌 Provider, ✨ Prompt & Styles, 🛡️ Safety & Budget, ⚡ Cache & Storage.
- Client ErrorBoundary Protection: Wrapped all settings forms and toolviews in an
ErrorBoundary with retry capability, preventing any component render crash from affecting DSH core UI.
- Full Host Config ↔ Client Fields Synchronization: Synchronized all 40 config properties between
Config schema in lib/index.js, staged FIELDS in lib/client.js, and localization dictionaries (en/ru). Exposes controls: qualityGate, dailyBudgetUsd, loopGuardLimit, diskCache, subscriptionQuality, cacheBySeed, cacheByPrompt.
- Complete Toolview Registration: Registered
tool.call.toolview for all 8 visual tools (generate_image, edit_image, vary_image, blend_images, generate_image_pack, remove_background, upscale_image, vectorize_image).
- Safety, Budget & Loop Guard Hardening: Extended
trackAndAssertLoopGuard, assertBudgetAvailable, and sanitizeErrorAndLogs error masking across edit_image, vary_image, blend_images, remove_background, and upscale_image. Added seedreamBaseURL support.
🚀 What's New in v0.10.13
- Plugin Settings Location (#208): Moved settings card exclusively into the standard
Settings → Plugins → Plugin settings section (settings.plugin.item slot). Removed the legacy fallback to settings.section that previously caused duplicate entries in the top-level sidebar navigation.
- Deferred Slot Injection (
registerSlotWhenReady): Implemented robust deferred injection via ctx.slots.inject ensuring the settings card safely mounts when the parent settings container is rendered, eliminating timing collisions at startup.
🚀 What's New in v0.10.12
- Fix Syntax Error (#208): Resolved variable redeclaration collision (
const hPrompt) in checkCache within lib/index.js which could prevent plugin initialization on strict Node.js runtimes. Added automated syntax check across all source modules to test suite.
🚀 What's New in v0.10.11 (#165, #166, #167, #168, #169, #170)
- Negative Prompt Sanitizer (#165): Automatic defect filtering and deduplication for diffusion models (SDXL, ComfyUI, Seedream, Local) with style-conflict protection (preserves intentional grainy, vintage, or dark aesthetics).
- Automated Quality Gate & Silent Re-roll (#166): Heuristic variance and sharpness inspection combined with
dsh-vision-bridge hook; performs silent re-rolls (up to 2 attempts) for blank, corrupted, or solid frames before returning results.
- Cost Metering & Daily Budget (#167): Full rate card pricing per provider and resolution, spend tracking in
~/.dsh/storages/dsh-image-gen-spend.json, dispatch to dsh-cost-meter, and hard daily budget enforcement via dailyBudgetUsd.
- Fail-Fast Loop Guard (#168): Session-scoped circuit breaker prevents runaway agent retry loops (default max 3 consecutive generations without user interaction).
- Secure Credential Masking (#169): Comprehensive masking of tokens in logs, URLs, and errors (
Bearer sk-...abcd), with 0600 file permission enforcement.
- Content-Addressed Disk Cache (#170): Instant retrieval (<50ms, zero API cost) for identical requests by SHA-256 hash, with automated LRU disk eviction (500 MB limit) and
force: true bypass.
🚀 What's New in v0.10.10 (#201, #203)
- Settings GUI Stabilization (#201): Fixed
booleanField spec in client runtime that prevented the settings configuration pane from rendering in DSH Web UI. All configuration fields (providers, model identifiers, API credentials, style presets, LLM enhancer, timeouts, cache retention) render cleanly.
- Streamlined Settings UI (#203): Removed the bulky in-settings history gallery to keep the configuration panel focused, fast, and organized.
- Comprehensive Localization (#201): Added 100% dictionary coverage for all provider credentials, endpoints, and field hints in English and Russian.
- Robust Slot Mounting: Implemented
registerFirst helper with graceful fallback between settings.plugin.item and settings.section.
