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.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00067 | $0.01292 |
| Opus 5 | $0.00034 | $0.00646 |
| Sonnet 5 | $0.00013 | $0.00258 |
| Haiku 4.5 | $0.00007 | $0.00129 |
Grade A, and why
trade-with-guardrails 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 12d 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 — 77 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Trade with guardrails
This is the only skill that can spend money. Everything below exists because an order placed by mistake cannot be taken back by another tool call.
Before anything
trading_status— first, every time. It tells you whether trading isoff,paperorlive, and every result in paper mode saysPAPER ACCOUNT — no real money.Say which mode you are in before you say anything else about an order. A user who thinks they are on paper and is not has been failed by you, not by the server.- If it is
off, the fix isstockbit-auth trading-enable --paper(or--live) at their terminal. You cannot turn it on, and no tool you can reach can write the settings file. Suggest--paper. - If they have never done this before, suggest paper. The protocol is identical on purpose — a rehearsal, not a shortcut.
- If it is
cash_balanceandposition symbol=…— what they actually have. Do not size a trade against a number the user guessed.
Sizing
position_size entry_price=… stop_price=… with either risk_idr or account_idr + risk_pct.
It returns whole lots, floored, with commission, break-even and R targets, and it checks both prices
against the IDX tick grid and today's auto-rejection band. Use its numbers. A price off the tick
grid is rejected by the exchange, not rounded by it.
The ticket protocol
order_preview action=buy symbol=… price=… lots=…— prices and validates the order and returns asummaryand a ticket id. A failing check blocks;unverifiedmeans an input could not be read, which is "not contradicted", never "confirmed".- Relay the
summaryto the user verbatim. Not paraphrased, not summarised, not "so that's about 5 million rupiah". The whole design assumes the human read that text. - Stop. Wait for the human.
order_buy ticket_id=…(ororder_sell,order_amend,order_cancel). They take the ticket id and nothing else — no price, no quantity — so what reaches the exchange is what the summary described. Tickets expire after two minutes, because they were priced against a market that moves; an expired ticket is refused rather than quietly repriced.
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.

trade-with-guardrails is a skill published in the GitHub repository INo-xious/stockbit-mcp (36 stars, last pushed 4d ago), licensed MIT. It adds 67 tokens to every session and 1,292 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings.
