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.

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 | $0.00094 | $0.02687 |
| Opus 5.5 | $0.00038 | $0.01075 |
| Sonnet 5.5 | $0.00019 | $0.00537 |
| Haiku 4.5 | $0.00009 | $0.00269 |
Grade A, and why
market-brief 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 1mo 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 — 320 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Market Brief
Intent
Generate a fast, structured market brief for Mick before or during the trading day. The brief covers index direction, commodities, currencies, expanded crypto, macro context, market-moving headlines, and only the flags that matter.
This is a situational awareness tool. It is not financial advice, trade execution guidance, or a signal service.
Do Not Use When
- Do not use for buy, sell, hold, price target, or guaranteed performance advice.
- Do not use for a deep single-stock or single-crypto research report when a research skill is a better match.
- Do not include an individual stock quote table unless the user explicitly asks for one outside the normal market brief.
- Do not answer from memory when current prices, market session state, economic events, or headlines are requested.
- Do not invent prices, changes, 52-week ranges, market hours, headlines, or sources.
Trigger When
Trigger immediately, search first, and do not ask clarifying questions when the user starts with:
mb
Also trigger on:
market briefmorning briefmarket updatepre-market summarymarket open summarywhat is the market doing
Instrument modifiers:
mb + SOL XRP COPPERmeans append those instruments to the relevant non-stock section for this brief only.mb only: BTC ETH DXY GOLDmeans use only those instruments for this brief.mb +depthmeans add the optional depth sections after Headlines.
Workflow
- Parse the request for
+instruments,only:override instruments, and+depth. - Determine the current market session: pre-market, regular session, after-hours, closed, weekend, or holiday if available.
- Verify current data before writing. Use reliable finance, exchange, brokerage, or market data pages where available.
- Gather current index levels and broad risk tone without adding individual stock quotes.
- Gather commodity prices and explain the inflation, growth, energy, or industrial demand read.
- Gather currency and rate-sensitive macro data, including DXY and major FX pairs.
- Gather expanded crypto data, including price, 24-hour change, 7-day change where available, market cap rank or dominance where relevant, and the main catalyst or risk.
- Gather 3 to 5 market-moving headlines from current sources.
- Populate only confirmed values. Use
--for unavailable values. - Build the brief in the required markdown format.
- Add Flags only when something is actually notable.
- End with the required one-line follow-up.
What ships with it
4 files 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.
