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 | $0.00062 | $0.05256 |
| Opus 5 | $0.00031 | $0.02628 |
| Sonnet 5 | $0.00012 | $0.01051 |
| Haiku 4.5 | $0.00006 | $0.00526 |
Grade A, and why
pipes-sdk 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 12d 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.
description: Build, configure, deploy, and troubleshoot durable blockchain indexers with the Subsquid Pipes SDK (EVM, Solana, Tron, Bitcoin, Hyperliquid) when Portal MCP or curl previews are insufficient for backfills, r How it starts

Pipes SDK
One skill for the full Pipes SDK lifecycle: scaffold new indexers, diagnose runtime errors, optimize sync performance, and validate data quality.
When to Use This Skill
Activate when the user wants to:
- Create a new indexer — scaffold EVM or Solana projects with the CLI; set up Tron, Bitcoin, or Hyperliquid indexers manually with the SDK
- Fix runtime errors — compilation failures, DB issues, Portal timeouts, decoding errors
- Optimize sync performance — slow indexing, high memory, large ranges
- Validate data quality — NULL checks, gaps, malformed addresses, duplicate events
- Deploy an indexer — local Docker or ClickHouse Cloud
- Write to analytics sinks: ClickHouse, PostgreSQL (Drizzle), BigQuery, Parquet files, Google Pub/Sub
- Turn a Portal handoff into durable infrastructure — when a Portal MCP answer or curl export is not enough
Common trigger phrases: "create a new indexer", "my indexer crashed", "error", "not working", "slow", "optimize", "deploy to ClickHouse Cloud", "track X events on Ethereum/Solana/Tron/Bitcoin/Hyperliquid".
Portal Handoff Workflow
Use Pipes when a Portal MCP or raw Stream API workflow crosses from exploration into a maintained data product.
Good Pipes triggers:
- long historical backfills
- recurring syncs or scheduled refresh
- protocol-specific joins
- normalized tables for an app/backend
- custom metrics, alerts, or dashboards
- transforms that should be versioned and tested
- data too large for MCP chat responses or one-off curl files
If the input includes a Portal pipes_handoff recipe, preserve its network, filters, time window, outputs, and validation hints. Treat the Portal MCP/curl result as the baseline, scaffold the indexer, and validate the first output against the closest Portal query over the same bounded window.
Before scaffolding, say why Pipes is the right surface. Portal MCP is best for bounded answers and investigation pivots; Portal Stream API/curl is best for reproducible one-off extraction; Pipes is best for durable indexing, transforms, and storage.

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.

pipes-sdk is a skill published in the GitHub repository subsquid-labs/portal-mcp-server (1 stars, last pushed 4d ago), licensed MIT. It adds 62 tokens to every session and 5,256 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
