Sindarin

Flip the Switch Hackathon/Nov 2026

Every company runs the same finance month, and most run it on email, spreadsheets and trust. Someone sets the targets, someone turns them into a budget, someone enters it. At month-end someone proposes the adjusting entries, someone decides which bills get paid, someone pays them, someone locks the period. Every deal with a discount needs a yes from the right level. The questions a CFO, a board or an auditor asks are always the same: who approved this, against what numbers, and did anything change between the approval and the money moving. Sindarin is that month run from the team's chat, with those questions answered by construction. The planning cycle, the close and the sales approvals happen in rooms where the controller, the CFO, the board and sales already are. Agents do the drafting and the reporting. A person with the right authority says yes, at the right level for the amount, in the right room. Only then does anything move, and the approval binds to the exact numbers it was given: if a sale lands or an invoice changes in between, the approval is refused and the proposal is redone. Segregation of duties, approval limits, single-use approvals and a full audit trail are not policies on a wiki, they are what the system is. It is for finance teams at small and mid-size companies that cannot afford an ERP's workflow engine but still have to close the books every month and defend every payment.

DeVries

Graph Hacks/Oct 2026

DeVries is an audit layer for systems of AI agents. You point it at the MCP servers and agents you already run, from Claude Desktop, Cursor, a command or a saved tools and it builds one FalkorDB graph of the whole system. From that graph it traces every path by which text written by an outsider, a support ticket, a GitHub issue, an email, could end up triggering a refund, a push to main or a deploy, and shows each path hop by hop with the rule behind every hop. For each finding it tries candidate fixes on a copy of the graph and proposes the cheapest one that closes the path without breaking a workflow. A person approves or rejects which no tool can. Nine example systems come audited out of the box, so there is something to read before you paste your own. It's for teams putting agents with real tools into production, and for whoever has to sign off on them.
