What is chafan-pwa CLAUDE.md?

Repository instructions for Chafan PWA, a Vue-based Chinese-language social question-and-answer website whose user interface is separate from its API service.

Use it when developing the frontend, running unit or browser tests, or promoting changes through preview and production deployments.

They document the code layout, testing commands, branches, and deployment flow, helping the agent avoid sending changes to the wrong environment.

Token cost

What it costs to keep this loaded

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	$0.01250	$0.01250
Opus 5.5	$0.00500	$0.00500
Sonnet 5.5	$0.00250	$0.00250

Security

Grade A, and why

chafan-pwa CLAUDE.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 2mo 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.

How it starts

The opening of the file, as written. The whole thing — 75 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Chafan PWA

Frontend-only SPA for a Chinese-language social Q&A site. The API is a separate service.

Stack: Vue 3 (<script setup>) · Vuetify 3 · Pinia · Vue Router 4 · Vite · TypeScript · Vitest (tests/unit/) · Playwright (e2e/)

Layout: src/views/ pages · src/components/ · src/stores/ (Pinia: main, ui, notifications) · src/composables/ (useAuth, useResponsive, useTheme, …) · src/styles/ (app.scss, variables.scss) · src/api/ + src/api.ts

Branches & deploys

ref	deploys to
`master` (tracks `public/master`)	— canonical source of truth
`deploy/preview`	preview.cha.fan
`deploy/master`	cha.fan (production)
`deploy/dev`	dev.cha.fan

public remote = canonical GitHub repo, where PRs land. deploy remote = the fork Cloudflare Pages builds. Promotion is a manual fast-forward: public/master → deploy/preview → deploy/master, via scripts/deploy-preview.sh / scripts/deploy-prod.sh.

scripts/deploy-preview.sh    # fetches public, pushes public/master -> deploy/preview
                             # then wait a few minutes for Cloudflare to build preview.cha.fan
scripts/deploy-prod.sh       # deploy/preview -> deploy/master, with confirmation + rollback tag

The scripts push the source ref's SHA straight to the deploy remote. Deploying does not go through any local branch — don't merge into a local preview/master first. The local preview branch is a vestige of the migration; it is not part of the deploy path.
git push has no --ff-only flag — a plain push already refuses non-fast-forwards. Never add it.
Production still serves the pre-migration Vue 2 build, so cha.fan is the visual reference: this tree must match its layout and behavior. That parity is the standing goal.

Migration hazards (read this before debugging any layout bug)

The Vue 2→3 / Vuetify 2→3 migration was largely a mechanical rewrite, so Vuetify 2 spellings that Vuetify 3 renamed still linger. They fail silently — no error, no warning, just wrong layout. If a layout bug has no JS error, suspect a dead class or prop before anything else. Confirm against node_modules/vuetify/dist/vuetify.css.

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.
