Reliability & compatibility
Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Deep Research Skill
When given a research task:
- Decompose the question into 3-5 sub-questions
- Search multiple sources for each sub-question using Bash + curl
- Cross-reference findings across sources
- Synthesize into a structured report with:
- Executive summary (3-5 sentences)
- Key findings (bullet points)
- Detailed analysis (organized by sub-topic)
- Sources cited
- Confidence level and caveats
Search Methods
# DuckDuckGo (no API key needed)
curl -s "https://html.duckduckgo.com/html/?q=QUERY" | grep -oP '(?]*>//g' | head -200
# Wikipedia API
curl -s "https://en.wikipedia.org/api/rest_v1/page/summary/TOPIC"
Quality Standards
- Never present a single source as definitive
- Flag conflicting information explicitly
- Distinguish facts from opinions
- Include dates/recency of information
- Rate overall confidence: HIGH / MEDIUM / LOW
