About the project

OpenAgent is a self-hostable personal AI assistant that combines language models, document-based retrieval, and autonomous agent loops. It lets people connect model providers and their own knowledge bases, then have agents browse the web, run code, use computers, and call MCP-compatible tools.

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

wacli 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 5d 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

wacli

Use wacli when the user asks you to message someone on WhatsApp or to sync/search WhatsApp history.

Safety

  • Require explicit recipient + message text.
  • Confirm recipient + message before sending.
  • If anything is ambiguous, ask a clarifying question.

Auth + sync

  • wacli auth (QR login + initial sync)
  • wacli sync --follow (continuous sync)
  • wacli doctor

Find chats + messages

  • wacli chats list --limit 20 --query "name or number"
  • wacli messages search "query" --limit 20 --chat <jid>
  • wacli messages search "invoice" --after 2025-01-01 --before 2025-12-31

History backfill

  • wacli history backfill --chat <jid> --requests 2 --count 50

Send

  • Text: wacli send text --to "+14155551212" --message "Hello! Are you free at 3pm?"
  • Group: wacli send text --to "[email protected]" --message "Running 5 min late."
  • File: wacli send file --to "+14155551212" --file /path/agenda.pdf --caption "Agenda"

Notes

  • Store dir: ~/.wacli (override with --store).
  • Use --json for machine-readable output when parsing.
  • Backfill requires your phone online; results are best-effort.
  • JIDs: direct chats look like <number>@s.whatsapp.net; groups look like <id>@g.us (use wacli chats list to find).
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.
