Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.
npx agentmods add instructions/builtbyoctane/allocat/claude-mdgit clone --depth 1 https://github.com/BuiltByOctane/allocatWhat 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 | $0.02522 | $0.02522 |
| Opus 5 | $0.01261 | $0.01261 |
| Sonnet 5 | $0.00504 | $0.00504 |
| Haiku 4.5 | $0.00252 | $0.00252 |
Grade A, and why
allocat 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 2d 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 — 119 lines — stays where its author put it; the contents beside it link to each section on GitHub.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Project
AlloCat — minimalist personal-finance PWA, also shipped as a native Android app (Capacitor) for SMS-based transaction tracking. Next.js 16 (App Router) + React 19 + Supabase + Dexie (IndexedDB) + TanStack Query 5 + Tailwind v4. Currency is multi-currency via lib/number-format.ts + lib/currency/catalog (INR is the default for legacy callers); do not assume hardcoded en-IN.
package.json declares name: "AlloCat-web" despite the directory name.
Commands
npm run dev # next dev
npm run build # next build && serwist build (service worker bundling)
npm run start # next start
npm run lint # eslint (flat config in eslint.config.mjs)
npm run test # vitest run (one-shot)
npm run test:watch # vitest (watch)
npx vitest run lib/sms/match.test.ts # single file
npx vitest run -t "matches exact rule" # single test by name
Test files live next to source (*.test.ts, e.g. lib/ai/parseSmsTransaction.test.ts, lib/sms/match.test.ts). No typecheck script — run npx tsc --noEmit if needed.
Use pnpm (per memory: npm install fails with ERESOLVE). Both package-lock.json and pnpm-lock.yaml are checked in.
Android (Capacitor)
npx cap sync android # copy web config + plugins into android/
CAP_SERVER_URL=http://192.168.1.20:3000 npx cap sync # point the shell at a LAN dev server
Requires Android Studio JBR (JDK 21). Open android/ in Android Studio to build/run the APK.
Required env (.env.local)
NEXT_PUBLIC_SUPABASE_URL=
NEXT_PUBLIC_SUPABASE_PUBLISHABLE_DEFAULT_KEY=
OPENROUTER_API_KEY= # used by app/api/ai/chat
Architecture
Offline-first sync (the central pattern — read this before touching data flow)
Every page reads from IndexedDB first; the network is a fallback and a background reconciler. Three layers cooperate:
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.

allocat CLAUDE.md is an instructions file published in the GitHub repository BuiltByOctane/allocat (10 stars, last pushed 1mo ago), licensed MIT. It adds 2,522 tokens to every session, about $0.0126 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
