PixivBiu is a Pixiv client for browsing artworks, users, rankings, collections, and followed accounts, with filtering and downloads for original images, multi-image works, and animations. It is used by people who want a desktop or server-based interface for searching and downloading Pixiv content. The catalogue entries provide instructions for working with the project.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.02407 | $0.02407 |
| Opus 5.5 | $0.00963 | $0.00963 |
| Sonnet 5.5 | $0.00481 | $0.00481 |
| Haiku 4.5 | $0.00241 | $0.00241 |
Grade A, and why
PixivBiu AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 22d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Project and scope
PixivBiu v3 is a Go backend + React SPA + Electron shell monorepo for browsing, searching, bookmarking, following, and downloading Pixiv artwork. The Go release embeds the SPA and runs as one portable executable. Docker packages that executable; desktop packages a pinned core with Electron.
Use this file for implementation constraints. Read the relevant linked guide before changing a subsystem; implementation explanations belong in those guides. Keep this root file concise (under 12 KiB). Write each prose paragraph on one source line; let the editor wrap it visually. Preserve Markdown block structure.
Sources of truth
| Subject | Authority |
|---|---|
| HTTP routes and wire models | OpenAPI spec, including referenced path files |
| Config keys, flags, defaults | Config structs and defaults; reflected schema and validators in the same package |
| Commands and dependencies | Makefile, go.mod, package manifests and lockfiles |
| Backend assembly and reload | app.go, reload.go, serve.go |
| Frontend patterns | frontend guide, existing feature implementations |
| Desktop policy and bridge | desktop guide, security.ts, preload.ts |
| Release behavior | workflows, .goreleaser.yaml, desktop packaging |
Reconcile prose against these sources when behavior changes. Do not change working code to match a stale example or infer features from historical notes. Do not read, print, or commit real tokens, proxy credentials, or signing secrets.
Read and verify by task
Commands below run from the repository root unless stated otherwise. Use the detailed development guide for setup and workflow order.
| Task | Read first | Relevant verification |
|---|---|---|
| Backend or HTTP API | Architecture, API workflow | Focused Go tests, go vet ./...; regenerate both clients after spec changes |
| Config or runtime paths | Configuration, adding settings | Config/runtimepath and affected service tests |
| Frontend | Frontend guide, message conventions | In frontend: bunx @biomejs/biome ci ., bun run build |
| Downloads, events, image proxy | Architecture | Affected Go tests; -race for concurrency changes; relevant UI scenarios |
| Desktop | Desktop guide | In desktop: npm run check; native smoke test for lifecycle/window changes |
| Packaging or releases | Release guide, Docker guide | Relevant config/build checks; publishing is a separate action |
| Documentation only | Docs index, cited source files | Links, anchors, command accuracy, factual consistency, git diff --check |
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
