# Coding Agent vs Finance Agent

**Short answer:** A coding agent writes and builds software. A finance agent discovers, allocates, and executes capital. Same architecture — model + harness + tools + memory — different object. Codex and Cursor are AI coding agents. Questflow is an AI Finance Agent: Codex for finance.

## The analogy that actually holds

|               | Coding agent                        | Finance agent                             |
| ------------- | ----------------------------------- | ----------------------------------------- |
| Object        | Code, tests, PRs                    | Capital, risk, orders                     |
| Loop          | Explore → Plan → Implement → Verify | Signal → Thesis → Execution → Post-mortem |
| Identity file | CLAUDE.md / AGENTS.md               | invest.md                                 |
| Danger        | Broken production                   | Broken account                            |
| Safety        | Hooks, tests, review                | Kill switch, limits, scoped permissions   |
| Proof         | CI green, review                    | Live performance ledger                   |
| Scarce input  | Taste in a codebase                 | Investor judgment                         |

Coding agents crossed the line when they stopped autocompleting and started owning tasks. Finance agents cross the same line when they stop chatting about charts and start closing the loop inside your rules.

## Where the analogy breaks

Markets punish you in a way compilers do not. A failing test is free. A failing thesis costs money. That is why Questflow insists the alpha source is **human fund manager judgment**, not a prompt that "generates a strategy." AI scales judgment. It does not invent it.

Also: code is usually one repo. Capital is fragmented across brokers, wallets, and venues. A financial harness has to read that whole picture before it writes an order.

## What to use when

* Building software → Codex, Cursor, Claude Code
* Allocating capital with someone else's proven framework → Questflow Funds
* Wanting a personal AI to vibe-trade your own untested ideas → that is a different product category (see Questflow vs Minara)
