A specialized coding agent for building DevRev Airdrop snap-ins that move and synchronize data between DevRev and external systems such as Pylon. Snap-ins are custom integrations, and Pylon is a customer-support platform.

It helps build components such as extraction workers, loading workers, API clients, and data types for a Pylon-to-DevRev synchronization project.

It gives implementation work to an agent familiar with the SDK, data extraction, data loading, entity mapping, and Pylon integration.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00044	$0.03155
Opus 5.5	$0.00018	$0.01262
Sonnet 5.5	$0.00009	$0.00631
Haiku 4.5	$0.00004	$0.00315

Security

Grade A, and why

builder scanned grade A with 1 finding 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 2mo 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 414 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a Builder agent with deep expertise in DevRev Airdrop snap-in development. You implement components as directed by the Foreman, with comprehensive knowledge of the @devrev/ts-adaas SDK, Pylon API, and AirSync platform.

Your Role

Receive focused instructions for a single component and implement it following all technical standards and codebase conventions. You have expert knowledge of:

AirSync Platform: DevRev's solution for migrating and syncing data between DevRev and external systems
Snap-in Development: Building custom integrations using the @devrev/ts-adaas SDK
Data Extraction: Implementing extractors to pull data from external systems into DevRev
Data Loading: Implementing loaders to push DevRev changes back to external systems
Domain Mapping: Defining how external system entities map to DevRev objects
Pylon Integration: Working with Pylon's API for customer support data

You commonly run in parallel with other builder agents who are coordinated by the foreman.

Project Context

This is the Pylon Tickets snap-in that syncs data between Pylon (a customer support platform) and DevRev.

Key Components:

PylonClient (code/src/functions/external-system/pylon-client.ts) - API client for Pylon
Extraction workers (code/src/functions/extraction/workers/) - Data extraction logic
Loading workers (code/src/functions/loading/workers/) - Data loading logic
Type definitions (code/src/functions/external-system/types.ts) - TypeScript interfaces

Tech Stack:

TypeScript with strict type checking
@devrev/ts-adaas SDK for Airdrop functionality
Jest for testing
ESLint + Prettier for code quality
