Agents could not distinguish 'keep retrying' from 'stop, this is
broken' (agent.feedback): retryable was emitted only when a registry
entry declared true — absent otherwise, including for genuinely
transient DB/network failures whose SQLSTATE is lost when tools wrap
them as Error('Database error: ...').
- StructuredError.retryable is now a required boolean. Registry
declaration wins; otherwise isTransientFailure() infers from Postgres
SQLSTATEs (40001/40P01/57014/08xxx/53xxx/55P03), upstream HTTP
statuses (408/429/5xx), and message signatures that survive wrapping
(deadlock, serialization, statement timeout, fetch/socket failures).
- Unclassified transient failures surface as stable code
TRANSIENT_ERROR (new registry entry, retryable: true).
- categorize_transaction accepts idempotency_key — the tool agents
blind-retry after client-side approval-elicitation drops; the key
makes that retry replay-safe instead of double-staging.
- Contract documented in .claude/rules/mcp-server.md. The planned
'kind' field was dropped: the code registry already encodes it;
retryable is the agent-actionable bit.
Every tool error already flows through the single dispatch point
(toToolError -> getStructuredError), so coverage is universal without
per-tool migration. Full unit suite: 6575 tests green.

Accounted
Open-source Swedish accounting software for sole traders (enskild firma) and limited companies (aktiebolag).
What is Accounted?
Accounted implements double-entry bookkeeping compliant with Swedish accounting law (Bokforingslagen). It supports the BAS 2026 chart of accounts, handles VAT declarations (momsdeklaration), SIE import/export, and enforces 7-year document retention. Built for sole traders and limited companies operating in Sweden.
Features
- Double-entry bookkeeping -- BAS 2026 chart of accounts, draft/commit workflow, sequential voucher numbering
- Invoicing -- Create, send, and track invoices with mixed VAT rates and PDF generation
- Bank reconciliation -- PSD2 bank connection via Enable Banking, 4-pass automatic matching
- VAT declaration -- SKV 4700 form mapping, per-rate breakdown, EU/export handling
- Tax reports -- NE-bilaga, INK2, SRU export for Skatteverket
- Supplier invoices -- Registration, payment tracking, input VAT deduction
- Document archive -- SHA-256 integrity, 7-year retention enforcement, full archive ZIP export
- SIE import/export -- Standard Swedish accounting interchange format
- Extension system -- Opt-in plugins for AI categorization, receipt OCR, email, calendar, and more
Self-Hosting
git clone https://github.com/erp-mafia/gnubok.git
cd Accounted
./setup.sh # Prompts for Supabase credentials, generates .env
docker compose up -d
You need a Supabase project and must apply the database migrations before first use. See SELF-HOSTING.md for the full step-by-step guide, including Supabase setup, auth configuration, optional features (AI, email, push notifications), and troubleshooting.
Development Setup
Prerequisites: Node.js 20+, a Supabase project.
npm install
npm run dev # Start dev server (auto-generates extension registry)
npm test # Run tests
npm run build # Production build
npm run lint # ESLint
