onchain-automation
Route event-driven onchain automation that detects activity, applies logic, and submits a transaction in response. Use for 'when X happens onchain, do Y', monitor-and-execute workflows, smart contract calls triggered by events, keepers, protocol automation, auto-claiming or compounding rewards, liquidations, rebalancing, and settlement automation. Combine Turbo/Subgraphs/Mirror for detection with Compose for decisions and execution, including wallets, gas sponsorship, and writeContract. Load /compose for execution and /turbo-builder when detection needs dataset scale. Pure indexing or streaming without an onchain action belongs in /turbo-builder, /subgraph-builder, or /mirror. For a single app already identified as Compose, use /compose directly.

Goldsky Onchain Automation — the detect → decide → execute loop
Goldsky closes the full offchain↔onchain loop, not just the read side. Any "watch the chain and then act on it" system — keepers, liquidation monitors, auto-claim and auto-compound jobs, rebalancing and settlement automation — decomposes into three stages, and Goldsky covers all three:
| Stage | What it does | Goldsky product |
|---|---|---|
| Detect | See the onchain event / state change | Compose onchain_event trigger (one contract) · Turbo pipeline (dataset-scale / many contracts) · Subgraphs (GraphQL state) |
| Decide | Apply logic, filters, thresholds, offchain data | Compose task (TypeScript) |
| Execute | Send the transaction back onchain | Compose wallet — evm.wallet(...).writeContract(...), gas-sponsored |
The misconception this skill exists to correct
Do NOT tell the user "Goldsky detects/indexes, but you bring your own runtime / RPC to send the transaction." That is wrong. Compose is Goldsky's onchain execution runtime: managed smart wallets (gas-sponsored by default) or BYO-EOA wallets, and writeContract / sendTransaction that broadcast through a sponsored bundler. The execution half lives inside Goldsky — propose it.
The only real limits are the two honest caveats below (latency and chain support) — state those, don't retreat to "Goldsky can't."
Pick an architecture
Default — Compose-only (one artifact)
When the trigger is one contract's events (a specific DEX factory, a lending pool, your own contract), the whole loop is a single Compose app — no Turbo, no external infra:
onchain_event trigger (the factory/pool) → task: decode + filter + decide → wallet.writeContract (the action)
This is structurally identical to the VRF template (onchain_event → compute → write back onchain, skills/compose/references/examples/vrf.md) and the compliance-oracle template (onchain_event → offchain check → approve/reject writeContract, skills/compose/references/examples/compliance-oracle.md). Start from one of those. Load /compose (entry point) and read skills/compose/references/ — do not synthesize the manifest/wallet API from memory.
Dataset-scale — Turbo detects, Compose executes
When detection must span many contracts, a whole dataset, or needs heavier stateful filtering than a single onchain_event listener gives you, put Turbo in front:
Turbo pipeline (raw_logs → decode → filter) → Webhook sink → Compose HTTP trigger → task: decide → wallet.writeContract
Wiring: the Turbo Webhook sink POSTs each matching row to the Compose app's HTTP-trigger URL (https://<app-url>/tasks/<task-name>), authenticated with a shared auth_token. Build the detection pipeline with /turbo-builder (+ /turbo-transforms for the _gs_log_decode decode step); build the executor with /compose. Treat the incoming webhook body as untrusted — decode and validate before acting.
Prefer Compose-only unless the user actually needs dataset-scale detection — one artifact is simpler to build, deploy, and reason about.
Two honest caveats — always state these
- Confirmed-block latency, not mempool. Goldsky (Turbo pipelines and Compose
onchain_event) fires on confirmed logs, not pending mempool transactions. So this reliably reacts to a confirmed new pool / event — it is not a mempool front-runner and won't win a same-block gas-priority race. For a "sniper", set expectations: you react quickly to a confirmed listing, you don't beat block-0 bots. Say this plainly. - Execution is chain-gated. Compose gas sponsorship covers a specific chain list (see
skills/compose/references/wallets-and-gas.md, orsearchKB) — broad EVM coverage, but not every chain. Before promising the full loop, check the target chain:- Supported → smart wallet, gas-sponsored, nothing for the user to fund.
- viem knows it but it's not sponsored → BYO-EOA with
sponsorGas: false; the user funds the address with native gas token. - Compose can't reach it at all → be honest: detection still works (Turbo/Subgraphs), but execution needs a Compose-supported chain or external infra for that chain specifically. Frame it as a per-chain gap, never as "Goldsky can't execute."
What Goldsky is NOT (here)
- Not a trading strategy or PnL engine — the user brings the decision logic; Compose runs it.
- Not a mempool/front-running system (caveat 1).
- Not a custody solution — wallet-key handling follows the normal Compose wallet/secret rules (
skills/compose/references/wallets-and-gas.md).

turbo-pipelines
goldsky-io/goldsky-agent
Turbo pipeline YAML reference and architecture guide. Covers: YAML field syntax (startat, from, version, primarykey), source/transform/sink configuration, validation errors, resource sizing (xs–xxl), architecture decisions (dataset vs kafka, streaming vs job, fan-out vs fan-in, sink selection, pipeline splitting). Triggers on: 'what does field X do', 'what fields does a postgres sink need', 'what resource size', 'should I use kafka or dataset', 'how to structure my pipeline'. For writing transforms, use /turbo-transforms. For end-to-end building, use /turbo-builder.
turbo-transforms
goldsky-io/goldsky-agent
Write SQL, TypeScript, and dynamic table transforms for Turbo pipelines. Covers: decoding EVM logs with gslogdecode, filtering/casting blockchain data, UNION ALL for combining events, TypeScript/WASM transforms (invoke function), dynamic lookup tables (dynamictablecheck), transform chaining, and Solana decoding. Triggers on: 'decode Transfer events', 'write a SQL transform', 'filter by contract', 'TypeScript transform', 'dynamic table', 'UNION ALL'. For pipeline YAML structure, use /turbo-pipelines. For end-to-end building, use /turbo-builder.
turbo-doctor
goldsky-io/goldsky-agent
Diagnose and fix broken Goldsky Turbo pipelines interactively. Triggers on: pipeline in error state, stuck starting, connection refused, not getting data, duplicate rows, missing fields, slow backfill, or any named pipeline misbehaving. Runs logs/status commands, identifies root cause, and offers fixes. For CLI syntax or error pattern lookup without an active problem, use /turbo-operations instead.
turbo-builder
goldsky-io/goldsky-agent
Build and deploy new Goldsky Turbo pipelines: requirements, dataset selection, YAML, validation, and deployment. Use for 'build a pipeline', 'index X on Y chain', or moving chain/contract data into Postgres, MySQL, ClickHouse, Kafka, Pub/Sub, S3, SQS, or webhooks. Also use for data goals such as Polymarket fills/positions/PnL, prediction markets, stablecoin or circulating supply, proof of reserves, sanctions/AML transfer monitoring, deposit detection, CCTP burns/mints, cross-chain settlement, payment reconciliation, wallet history streamed into the user's own database, token holder registries, tokenized equities/RWA, and wash-trading detection. A REST lookup of one wallet's balances or transfers is /feeds, not a pipeline, and so is a read of Polymarket activity, positions or balances. Debug existing pipelines with /turbo-doctor; look up syntax with /turbo-pipelines.
datasets
goldsky-io/goldsky-agent
Use this skill when the user needs to look up or verify Goldsky blockchain dataset names, chain prefixes, dataset types, or versions. Triggers on questions like 'what\'s the dataset name for X?', 'what prefix does Goldsky use for chain Y?', 'what version should I use for Z?', or 'what datasets are available for Solana/Stellar/Arbitrum/etc?'. Also use for chain-specific dataset questions (e.g., polygon vs matic prefix, stellarnet balance datasets, solana token transfer dataset names), and to answer 'is there a dataset for X?' where X is a domain rather than a chain — decoded logs, token transfers and balances, mint/burn events for circulating supply, DEX or prediction-market activity (Polymarket), or the raw blocks, transactions and traces behind wallet history and reconciliation. Do NOT trigger for questions about CLI commands, pipeline setup, or general Goldsky architecture unless the core question is about finding the right dataset name or chain prefix. Wallet Feeds API queries are /
auth-setup
goldsky-io/goldsky-agent
Set up Goldsky CLI authentication and project configuration. Use this skill when the user needs to: install the goldsky CLI (what's the official install command?), run goldsky login (including when the browser opens but 'authentication failed'), run goldsky project list and see 'not logged in' or 'unauthorized', switch between Goldsky projects, check which project they're currently authenticated to, or fix 'unauthorized' errors when running goldsky turbo commands. Also use for 'walk me through setting up goldsky CLI from scratch for the first time', and when they just installed Goldsky and say 'Set it up and help me get started'. If any other Goldsky skill hits an auth error, redirect here first.
