builder

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.

In plain words
What is it for?
It helps build components such as extraction workers, loading workers, API clients, and data types for a Pylon-to-DevRev synchronization project.
Why use it?
It gives implementation work to an agent familiar with the SDK, data extraction, data loading, entity mapping, and Pylon integration.

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.

agentmods
npx agentmods add agents/mgmonteleone/pylon-mcp/builder
Clone the repo
git clone --depth 1 https://github.com/mgmonteleone/pylon-mcp
Per session 44 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 3,155 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 1 finding. Scan, not verified.
Origin fork From a forked repository.
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

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 2d 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

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.

builder is an agent published in the GitHub repository mgmonteleone/pylon-mcp (0 stars, last pushed 2mo ago), licensed MIT. It adds 44 tokens to every session and 3,155 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). It comes from a forked repository.
