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.

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 | $0.00046 | $0.00763 |
| Opus 5 | $0.00023 | $0.00381 |
| Sonnet 5 | $0.00009 | $0.00153 |
| Haiku 4.5 | $0.00005 | $0.00076 |
Grade A, and why
dbos-typescript 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 8d 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.
This is a copy
86% identical to dbos-golang — 88 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

DBOS TypeScript Best Practices
Guide for building reliable, fault-tolerant TypeScript applications with DBOS durable workflows.
When to Use
Reference these guidelines when:
- Adding DBOS to existing TypeScript code
- Creating workflows and steps
- Using queues for concurrency control
- Implementing workflow communication (events, messages, streams)
- Configuring and launching DBOS applications
- Using DBOSClient from external applications
- Testing DBOS applications
Rule Categories by Priority
| Priority | Category | Impact | Prefix |
|---|---|---|---|
| 1 | Lifecycle | CRITICAL | lifecycle- |
| 2 | Workflow | CRITICAL | workflow- |
| 3 | Step | HIGH | step- |
| 4 | Queue | HIGH | queue- |
| 5 | Communication | MEDIUM | comm- |
| 6 | Pattern | MEDIUM | pattern- |
| 7 | Testing | LOW-MEDIUM | test- |
| 8 | Client | MEDIUM | client- |
| 9 | Advanced | LOW | advanced- |
Critical Rules
Installation
Always install the latest version of DBOS:
npm install @dbos-inc/dbos-sdk@latest
DBOS Configuration and Launch
A DBOS application MUST configure and launch DBOS before running any workflows:
import { DBOS } from "@dbos-inc/dbos-sdk";
async function main() {
DBOS.setConfig({
name: "my-app",
systemDatabaseUrl: process.env.DBOS_SYSTEM_DATABASE_URL,
});
await DBOS.launch();
await myWorkflow();
}
main().catch(console.log);
Workflow and Step Structure
Workflows are comprised of steps. Any function performing complex operations or accessing external services must be run as a step using DBOS.runStep:
import { DBOS } from "@dbos-inc/dbos-sdk";
async function fetchData() {
return await fetch("https://api.example.com").then(r => r.json());
}
async function myWorkflowFn() {
const result = await DBOS.runStep(fetchData, { name: "fetchData" });
return result;
}
const myWorkflow = DBOS.registerWorkflow(myWorkflowFn);

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.
- 8d ago First seen · 110 lines · 46 tokens per session scan A 271e77e4c2e5
dbos-typescript is a skill published in the GitHub repository tmolavi/mcp-agent-skills-hub (8 stars, last pushed 16d ago), licensed MIT. It adds 46 tokens to every session and 763 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 86% identical to dbos-golang, differing in 88 lines, and is treated as a copy.
