dsh-finance
A finance and accounting plugin for DeepSeek Harness.
Version 0.2 is a capability-level DSH adaptation of Anthropic's official finance plugin, not merely a finance-themed workflow. It ports the upstream plugin's eight skills for journal entries, reconciliation, financial statements, variance analysis, close management, SOX testing, and audit support, then adds deterministic DSH validation tools.
The source baseline is Anthropic Finance 1.3.0 at commit a006314. This is an independent community adaptation and is not endorsed by Anthropic.
Upstream parity
| Anthropic Finance skill | DSH skill | Coverage |
|---|---|---|
journal-entry | dsh-finance-journal-entry | Accruals, depreciation, prepaids, payroll, revenue entries, support, and review |
journal-entry-prep | dsh-finance-journal-entry-prep | Standard entry patterns, documentation, approval matrix, and error checks |
reconciliation | dsh-finance-reconciliation | GL-to-subledger, bank, intercompany, aging, categorization, and escalation |
financial-statements | dsh-finance-financial-statements | Income statement, balance sheet, cash flow, GAAP/IFRS presentation, and period-end adjustments |
variance-analysis | dsh-finance-variance-analysis | Price/volume, rate/mix, headcount, spend, materiality, narratives, and waterfalls |
close-management | dsh-finance-close-management | T+1 to T+5 close calendar, dependencies, critical path, status, and retrospectives |
audit-support | dsh-finance-audit-support | SOX scoping, assertions, sampling, evidence, workpapers, and deficiency classification |
sox-testing | dsh-finance-sox-testing | Control matrices, sample selection, test steps, conclusions, and remediation |
All eight skills preserve the upstream workflows and detailed reference content. Claude-specific invocation and connector assumptions were changed for DSH, and every modified file carries an adaptation notice.
DSH tools
The plugin registers five tools:
finance_journal_entry_checkvalidates debit-credit balance, line structure, documentation gaps, and preparer/approver separation. It never authorizes posting.finance_reconciliation_snapshotcalculates adjusted balances, item aging, category totals, stale-item flags, and sign-off readiness. It never authorizes sign-off.finance_variance_bridgeproves that signed drivers bridge base to actual, exposes residuals, and evaluates materiality thresholds.finance_research_workflowplans source-backed public-market research.portfolio_risk_snapshotcalculates exposure and concentration controls from supplied positions.
The last two are DSH extensions retained from version 0.1. They are not presented as part of Anthropic Finance parity.
Install

Prepare the July AP accrual journal entry, show the support, and validate that debits equal credits.
Reconcile the cash GL to the bank statement as of 2026-07-31 and age every open item.

The skills use tool categories such as ~~erp, ~~data warehouse, and ~~office suite. See CONNECTORS.md and connectors.example.json.
Installation does not activate external servers or collect credentials. Without a connected source, DSH must request pasted data or local files and state the resulting evidence limitation.
Human approval boundary
This plugin prepares and validates analyst work product. It does not post journal entries, lock accounting periods, send reports, sign off reconciliations, approve controls, or make investment decisions. Those actions remain with authorized people in the relevant system.
All outputs require review by qualified financial professionals before use in reporting, filings, audit documentation, tax work, or investment decisions.
