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 | $0.00129 | $0.01944 |
| Opus 5 | $0.00064 | $0.00972 |
| Sonnet 5 | $0.00026 | $0.00389 |
| Haiku 4.5 | $0.00013 | $0.00194 |
Grade A, and why
haruspex-stock-analyst 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 — 166 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Haruspex Stock Analyst
What this skill does
Runs a structured single-ticker analysis using the Haruspex API via the
@haruspex-guru/mcp-server MCP server. The analysis covers: the headline score,
the bull/bear outlook, the buy/hold/sell signal, the strongest positive and
negative topic dimensions, the 30-day score trajectory, and recent news
context where it explains a material score change.
The output is analysis, never advice. The user gets a structured read of what the data shows, plus a verifiable link to the live analysis page.
When to use this skill
Trigger on any of these patterns:
- "What do you think about [TICKER]?"
- "Should I look at [COMPANY]?" / "Is [COMPANY] interesting?"
- "Score for NVDA?" / "Rating on AAPL?"
- "Analyze TSLA" / "Deep dive on MSFT"
- "What's driving [TICKER]?"
- A user mentions a single company by name in the context of investing.
Defer to a sister skill if:
- The user lists 3 or more tickers → use
haruspex-watchlist-review. - The user states a thesis or rationale for owning the stock → use
haruspex-thesis-tracker. - The user is writing in Japanese → use
haruspex-stock-analyst-ja.
Prerequisites
This skill requires @haruspex-guru/mcp-server to be installed and connected.
First action: verify the MCP tools are available.
If the tools get_stock_score, get_stock_score_history, search_stocks,
and get_stock_news are not available, output the install instructions from
shared/MCP_SETUP.md and stop. Do not
attempt analysis without live data.
Workflow
Step 0 — Telemetry ping (do this first, always). Before any other tool
call, invoke record_skill_invocation once with skill: "haruspex-stock-analyst"
and client set to the best-guess client surface (e.g. claude-code,
claude-desktop, claude-ai). This is anonymous aggregate telemetry — only
the skill name, version, and client tag travel. No tickers, no conversation,
no user identifiers. The call is fail-silent: if it errors or the tool is
unavailable, ignore it and continue. Do not retry, do not surface the result
to the user, and never block the analysis on this step.
What ships with it
2 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.
