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.

Security

Grade A, and why

desk 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 — 335 lines — stays where its author put it; the contents beside it link to each section on GitHub.

PREREQUISITE: Read ../../SKILL.md (two directories up from this file) first. It defines identity, MCP setup, TUI /connect handshake, render protocol, and the shape catalog. This file handles only the sub-skill-specific flow.

Desk - Quick Market Snapshot

30 seconds. One thing the floor needs to know.

The fastest sub-skill. 3–5 MCP calls. Under 5 seconds. No depth questions, no focus questions, no theme questions. Just data.

Loaded after the main Heurist Finance router - MCP setup and tool tables are already complete. All tools use the mcp__heurist-finance__ prefix.

Desk Posture

Lead with the single most important thing happening right now. Not a list of facts - one sentence that a portfolio manager scanning the tape needs to hear.

No equivocation. If nothing matters, say "quiet tape, nothing actionable."


Entry Logic

args contain a ticker or company name?
  YES → skip all questions, go straight to Data Pipeline (Ticker Mode)
  NO  → ask ONE question: broad market or a specific name?
        → branch on answer

That is the only question ever asked. No depth. No focus. No theme.

User Impatience Protocol

If the user says anything that makes intent clear ("just show me the market", "what's NVDA at", "quick check"): skip the question entirely and go. The whole point of Desk is zero friction.


Session Memory

Before any MCP calls: read ~/.heurist/sessions/*.json. Filter by sub_skill === "desk". Sort by timestamp descending, take last 5. Note prior market pulse for comparison ("yesterday: bullish, today: risk-off"). First run (no sessions dir): skip silently.


Data Pipeline

Voice reminder: Between phases, if you speak to the user, it's a finding - not a status update. Never narrate what you're fetching.

Ticker Mode (3 calls)

Run all in parallel after resolving the symbol:

  1. mcp__heurist-finance__yahoofinanceagent_resolve_symbol - get canonical symbol + name
  2. mcp__heurist-finance__yahoofinanceagent_quote_snapshot - price, change, volume, market cap
  3. mcp__heurist-finance__yahoofinanceagent_technical_snapshot - RSI, MACD, signals

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.
