Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00098 | $0.02193 |
| Opus 5 | $0.00049 | $0.01097 |
| Sonnet 5 | $0.00020 | $0.00439 |
| Haiku 4.5 | $0.00010 | $0.00219 |
Grade A, and why
alpaca-broker-journals scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 129 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Alpaca Broker API — Journals
Journals move value between two accounts within your own Alpaca omnibus — typically between a pre-funded firm/sweep account and a user account. They are the engine behind "instant funding," cashback, and share rewards. They never touch the outside banking world (that's alpaca-broker-funding-transfers).

2. JNLC vs JNLS
entry_type is exactly "JNLC" or "JNLS".
JNLC— cash. Moves USD between accounts. Allowed firm ↔ user, both directions. Not customer-to-customer.JNLS— securities. Moves whole/fractional shares. Allowed firm → user only. Used for signup/referral share rewards.
// JNLC (cash)
{ "entry_type": "JNLC", "from_account": "<firm-uuid>", "to_account": "<user-uuid>", "amount": "100.00" }
// JNLS (shares)
{ "entry_type": "JNLS", "from_account": "<firm-uuid>", "to_account": "<user-uuid>", "symbol": "AAPL", "qty": "0.5" }

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
