Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00041 | $0.05890 |
| Opus 5 | $0.00020 | $0.02945 |
| Sonnet 5 | $0.00008 | $0.01178 |
| Haiku 4.5 | $0.00004 | $0.00589 |
Grade A, and why
build-connector 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 10d 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.
How it starts
The opening of the file, as written. The whole thing — 411 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are helping build a connector for Omni, an open-source AI agent platform for the workplace. Connectors are lightweight bridges between Omni and third-party systems: they sync workplace data into Omni's index and expose safe actions, MCP tools, resources, and prompts that workplace agents can use.
Core Principles
- One container per connector. Independently packaged and deployed.
- Connectors never interact directly with Omni services. Everything goes through connector-manager via the SDK.
- SDKs are local dependencies in this monorepo, not published package registries.
- Python, TypeScript, and Rust are first-class. Pick the language that best fits the provider SDK/ecosystem.
- Agents depend on connector contracts. Model read/write actions, permissions, OAuth scopes, resources, prompts, and document IDs carefully.
Scheduled sync flow: connector-manager creates a sync run -> sends POST /sync to the connector -> connector fetches source config/credentials through the SDK -> connector fetches provider data -> stores/extracts content via SDK -> emits events -> checkpoints as it advances -> completes or fails through SDK.
Realtime sync flow: connector-manager starts/monitors a long-running realtime sync when the manifest declares support -> connector keeps a webhook/socket/watcher alive, heartbeats while idle, and emits repair/update events or creates short follow-up sync runs as needed.
Checklist
Every new built-in connector usually requires changes across these areas:
- Connector implementation — sync logic, provider client, config/credential types, manifest, actions/tools/resources.
- Database migration — add source type to
sources_source_type_check; add service provider toservice_credentials_provider_checkif new. - Rust
SourceTypeenum — add variant inshared/src/models.rseven for Python/TS connectors, because connector-manager is Rust. - Frontend —
SourceType,ServiceProviderif new, icon, setup dialog, integrations page, sync interval defaults. - Docker Compose — service definition, dev override, port in
.env.example,ENABLED_CONNECTORScomment. - Terraform — AWS ECS task/service and GCP Cloud Run service.
- GitHub Actions — path filter, build job, release matrix entry.
- Integration tests — mock provider API, connector-manager/testcontainer harness, sync/action assertions.
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.

build-connector is a skill published in the GitHub repository getomnico/omni (773 stars, last pushed today), licensed Apache-2.0. It adds 41 tokens to every session and 5,890 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
