Computer-use tools
Tools are registered with the harness and exposed through the daemon. The
observable contract includes cu.grant, cu.revoke, cu.status,
cu.observe, cu.zoom, cu.tree, cu.find, cu.click, cu.drag,
cu.scroll, cu.type, cu.key, and cu.act. Every action is checked against
the active grant and safety policy. The HUD shows visible CU chrome (target
highlight and agent cursor), not a waveform overlay.
Search tools
Implemented in vendor/agent-harness/agent/web-search.js for Bare (fetch plus
regex/JSON, no extra npm, no SearXNG):
| Tool | Behavior |
|---|---|
web_search |
Public search. Default engine=auto merges and deduplicates direct HTML/RSS scrapes from DuckDuckGo, Bing, and Google. Pin engine to retry one backend. |
google_search |
Google HTML first, then the auto chain |
fetch_page |
Direct JavaScript scraping: readable text, links, headings, metadata; offset, max_chars, and find support continued reading |
web_fetch |
Direct scraped text, including IP lookup pages |
wiki_search |
Wikipedia MediaWiki JSON |
hn_search |
Hacker News via Algolia |
code_search |
GitHub, npm, and MDN in parallel |
These are public reads implemented in JavaScript with no scraping libraries, API keys, JSON search APIs, or hosted reader services. Specialized searches use site-restricted scraped search results. Pages requiring JavaScript execution or bot challenges may be unreadable. Shell HTTP
(curl/wget over public hosts) remains blocked; use these tools instead.
Local HTTP
QVAC's optional OpenAI-compatible server is localhost-only at port 11434.
It is a diagnostic surface, not a second Jarvis runtime. Native QVAC-only
operations use /qvac/v1/* where supported by the installed QVAC version.
