GOWA is a Go server that exposes WhatsApp through a REST API and supports multiple accounts, webhooks, a user interface, MCP, and Chatwoot integration. It is for applications and automations that need to connect to and manage WhatsApp accounts programmatically. The catalogue entries provide skills and instructions for working with GOWA.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.01341 | $0.01341 |
| Opus 5.5 | $0.00536 | $0.00536 |
| Sonnet 5.5 | $0.00268 | $0.00268 |
| Haiku 4.5 | $0.00134 | $0.00134 |
Grade A, and why
go-whatsapp-web-multidevice AGENTS.md 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 7d 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.

Working on GOWA
GOWA is a Go WhatsApp API server using whatsmeow, Fiber, and SQLite. The Go module
and local runtime directory are src/. rest also mounts MCP at /mcp when
enabled; both transports share the same device manager and usecases.
WhatsApp protocol verification
- whatsmeow is GOWA's base WhatsApp library. Every agent working on WhatsApp protocol behavior must verify relevant assumptions against upstream source and documentation before implementing or reviewing changes.
- Use the version pinned in
src/go.mod(and any applicable module replacement). Inspect the matching module source or upstream revision; do not assume upstreammainmatches GOWA's dependency. This applies to messages, events, JIDs, receipts, presence, authentication, sessions, and protocol types. - Identify the upstream files or symbols checked in the work summary. If the relevant source is unavailable or behavior remains uncertain, state that limitation rather than claiming protocol verification. Preserve GOWA's own API contracts and application behavior when integrating upstream behavior.
Working scope and completion
- Use the applicable scoped
AGENTS.mdand task-relevant source. The entry points below are routing hints; follow the ones needed for the affected behavior. - For multi-step work, identify the requested outcome and how to verify it. Continue through implementation, relevant checks, and fixes caused by the change. When the request includes running or inspecting the result, include that in completion. If blocked, report what remains and the specific missing input or access.
- Preserve unrelated working-tree changes. Keep
.env, SQLite databases, session data, QR codes, generated media, and history dumps out of commits. - Local tests using temporary databases, mocks, and fake clients can be run and repaired within the task without repeated approval. Running the app against saved sessions can reconnect real WhatsApp devices; use that runtime only within the user's authorized scope.
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.
