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 →

    Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.
    Fix: Remove all code or instructions that list or read other skills' files or directories. Skills should operate independently; cross-skill access is a privilege escalation.

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

pmxt 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.

What it actually says

PMXT prediction-market research

Use the pmxt_* tools for read-only market discovery and diagnostics.

Start with pmxt_runtime_status when a backend may be unavailable. Use pmxt_events for broad topics and pmxt_search for specific markets. Present prices as probabilities, preserve venue and outcome labels, and do not claim that similar titles represent equivalent contracts.

Use pmxt_series for venue-native series and pmxt_order_books when comparing multiple known outcome IDs. pmxt_matched_market_clusters is the preferred cross-venue comparison entry point: it returns PMXT relation/confidence evidence, not title-overlap guesses. Treat any spread as a research lead; contract rules, fees, liquidity and settlement must still be checked before making a decision.

This bundled native-plugin skill intentionally does not provide trade submission, cancellation, funding, or wallet operations.

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.
