Frequently asked questions
What counts as an observation?
Any piece of knowledge your AI agent captures: a discovery, decision, bugfix, pattern, or change. Each observation is a single structured record with a title, narrative, and metadata. Digests (compacted summaries) also count.
Do early adopters really get free accounts?
Yes. Everyone who joins the waitlist before launch gets a permanent free account with the same limits as the Free tier. No time limit, no catch.
What is the Vibe plan?
The Vibe plan is designed for developers who ship fast and want more than the basics. At $9/mo you get hybrid search, all help packs, Sentinel advisory mode with 50 audits/day, and 90-day retention — the sweet spot between free and pro.
Can I self-host?
The MCP server and local database run entirely on your machine. For sync and team features, you can either use our hosted Candengo Vector service or deploy your own instance with a deployment key.
What happens when I hit my observation limit?
Your agent can still read and search existing observations. New observations will queue locally and sync when you upgrade or when lifecycle compaction frees up space.
What LLM providers does Sentinel support?
Any OpenAI-compatible API: OpenAI, Anthropic, Grok (xAI), Mistral, Ollama (local), vLLM (local), or any custom endpoint. You provide the API key; Sentinel does the rest.
Is my data private?
Your local SQLite database is yours. Secret scrubbing strips API keys and credentials before storage. Sync uses encrypted connections. Team observations respect visibility rules — personal stays personal.
What's the difference between advisory and blocking mode?
Advisory (Vibe and Pro) shows warnings in the Sentinel feed but lets the agent proceed. Blocking (Team) returns exit code 2, which stops the tool call and forces the agent to fix the issue before continuing.
