A command for recording completed investment trades from natural-language descriptions in a holdings file and an audit log.

Use it after buying or selling shares to record the action, ticker, quantity, price, account, date, and currency, including additions, trims, and closing positions.

It reduces manual bookkeeping by extracting the trade details, updating average cost basis, checking holdings before sales, and asking about missing critical information.

Token cost

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	$0.00032	$0.01439
Opus 5.5	$0.00013	$0.00576
Sonnet 5.5	$0.00006	$0.00288
Haiku 4.5	$0.00003	$0.00144

Measured 2mo ago against content hash 7928d7a8925d, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

trade 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 2mo 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 — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/trade -- Sync Completed Trade

Record a trade the user executed on their broker platform. Updates holdings.json and logs to memory/long_term/trades.md for audit trail.

Input

Natural language from $ARGUMENTS, examples:

昨天在 broker-a-taxable 买了 20 股 NVDA @ $195
sold 50 AAPL from broker-a-taxable at $182 today
TFSA 加仓 SHOP.TO 30 股 @CAD$175, 成本摊到均价
trim half of MSFT in broker-a-taxable at $420

Steps

Parse the trade. Extract:
- Action: buy / sell / add / trim / close
- Ticker -- normalize class-share suffix: BRK.B / BRK/B → BRK-B, BF.B → BF-B (yfinance quirk per CLAUDE.md). Store the yfinance-valid form in holdings.json.
- Shares
- Price
- Account (match to holdings.json account_id -- or ask if ambiguous)
- Date (default today if not specified)
- Currency (infer from account's base_currency)
Ask once if critical info missing. Don't over-ask. If user wrote "bought NVDA in broker-a-taxable" without shares/price, ask one question: "How many shares and at what price?"
Validate.
- If selling, does the account actually hold this ticker + enough shares?
- If TFSA buy of high-yield US stock → flag the withholding trap before proceeding. Sanity-check yfinance dividendYield per CLAUDE.md quirks: divide by 100 if > 15%, or recompute from trailingAnnualDividendRate / currentPrice. Don't flag trap on a false-high yield number.
- If position size after trade crosses a concentration tier (see CLAUDE.md: ≤7% neutral, 7-12% flag, 12-20% DRAFT, >20% HIGH-RISK) → note the tier in confirmation. Trades don't block -- /trade records what already happened.
- If buying with insufficient cash in the account → flag and ask whether to deduct from cash or assume deposit arrived
Update holdings.json.

IMPORTANT -- Canadian ACB is pooled across ALL accounts for the same identical property. CRA treats identical property held in multiple accounts as ONE pool for cost basis purposes. This means:
