## Which one, for what

### Cursor Agent SDK (B)

Good for: Teams already on Cursor who want version-controlled agents for pull request review, triage and Slack, with evals in CI and one-command hosting.

Ahead on:
- Schema & documentation, 82 against 61
- Agent ergonomics, 80 against 61
- Security & auth, 68 against 62

Watch for: Closed source under Cursor's terms, with no public repository, CI or issue tracker

### TradingAgents (B)

Good for: Researchers who want a fixed multi-agent analysis of one listed instrument or crypto pair on a date, with point-in-time data for backtests, and who will run Python.

Ahead on:
- Reliability, 67 against 45
- Payments & pricing, 60 against 30
- Maintenance & community, 82 against 74

Also in its favour:
- Open source

Watch for: No MCP client or MCP server, so an agent drives it only through Python or the CLI

## Verdicts

**Cursor Agent SDK.** An agent-as-code framework with typed tools, declared read and write effects that drive retries and dry runs, an approval gate per tool and evals that assert on tool calls. It's closed source, every model turn runs through Cursor's backend on a Cursor plan, local sandboxing is off by default, and the changelog has two entries.

**TradingAgents.** An Apache 2.0 LangGraph framework at 0.7.0 with six releases in 90 days, a dated changelog with upgrade notes, a public test matrix and point-in-time rules for historical runs. It has no MCP client or server, no PyPI package and no documentation beyond the README, and its output is a model-written rating that places no orders.

## Before you call either

### Cursor Agent SDK

1. Install `@grok/agent-sdk`, not `@cursor/agent-sdk` from the launch post. That name answers 404 on npm
2. Set `local.sandbox` before a turn reads webhook payloads, pull request diffs or chat. Without it shell commands auto-approve with the host's credentials
3. Give every tool an `effect`. A tool without one counts as a write, runs once and is stubbed in dry runs
4. Start `agent-sdk serve` with `--bearer-token` on any shared host. `--allow-anonymous` admits every caller as one principal
5. Delete bot/hooks/memory.ts when sessions serve different people. The journal shares each turn's message and result with later turns

### TradingAgents

1. Run headless with `tradingagents --ticker <T> --date <YYYY-MM-DD> --analysts market,news,fundamentals --save --no-show`; a missing answer stops the run and names the flag
2. Guard on the REVIEW signal before mapping `propagate()`'s decision to a rating; it means no rating could be parsed
3. Set SEC_EDGAR_USER_AGENT to the operator's own name and address before fetching US fundamentals
4. Keep provider keys out of the working directory tree unless intended, since the package loads the nearest .env on import
5. Treat the rating as model output for research; the framework places no orders and its results vary between runs
