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 →

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

defeatbeta-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 9d 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.

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.

Financial Analyst

Professional-grade financial analysis using historical market data and comprehensive financial metrics from the defeatbeta dataset.

Defaults

Unless the user specifies otherwise:

  • Always call get_latest_data_update_date first — this is "today" for all relative time queries
  • Default analysis: When given only a ticker (e.g., /defeatbeta-analyst AAPL), run Template 1: Quick Investment Screening
  • ROIC and Equity Multiplier: Not applicable to banks/financial institutions — check sector in profile first
  • Date format: "YYYY-MM-DD"
  • Data limits: Price/valuation APIs return max 1000 rows — use date ranges for large datasets

Template Selection

Choose the template that best matches the user's request. Read analysis-templates.md for the full workflow of any template.

Changes

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.
