subgraph-doctor is a skill for Claude Code from goldsky-io/goldsky-agent. It costs 214 tokens per session (3,614 once invoked), scanned A, original, MIT.

A debugging and repair tool for Goldsky subgraphs, which provide searchable APIs over blockchain data. It handles problems such as failed deployment, indexing errors, stalled syncing, automatic pauses, and query errors.

In plain words
What is it for?
Use it to diagnose and fix subgraphs that fail to deploy, stop syncing, get stuck at a block, or return errors.
Why use it?
It helps identify why a subgraph is not processing blockchain data or serving requests correctly.

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

subgraph-doctor 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 21d 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.

Subgraph Doctor

Diagnose and fix existing Goldsky Subgraph problems by running CLI commands, reading logs, identifying root causes, and executing fixes.

Boundaries

  • Diagnose and fix EXISTING subgraph problems.
  • Diagnose only subgraphs that are broken (failing, stalled, erroring, won't deploy). A healthy but slow subgraph is an optimization task — use /subgraph-builder (e.g. reducing/declaring eth_calls).
  • Do not build or scaffold new subgraphs — use /subgraph-builder for authoring/init/deploy.
  • Do not handle The Graph migrations — use /subgraph-migrate.
  • Do not serve as a command reference — use /subgraph-builder or goldsky subgraph <cmd> --help for CLI syntax and flag lookups.
  • Do not handle Turbo or Mirror pipelines — use /turbo-doctor or /mirror-doctor.
  • Customer-facing only. Use only goldsky CLI commands, the dashboard, and GraphQL queries. Never suggest graphman, kubectl, Datadog, or direct database access — those are internal Goldsky tooling. When a problem needs them, escalate to support (see Step 6).

Mode Detection

Before running anything, check if you have the Bash tool:

  • Bash available (CLI mode): Run commands directly and parse output.
  • Bash NOT available (reference mode): Give the user one command at a time, explain what to look for, and proceed based on what they paste back.

Diagnostic Workflow

Follow these steps in order. Each builds on the previous one.

Step 1: Verify Authentication

Run goldsky project list 2>&1 to confirm the user is logged in.

  • If logged in: Note the project name and continue.
  • If not logged in: Direct the user to /auth-setup. Do not proceed until auth works.

Step 2: Identify the Subgraph

Run goldsky subgraph list 2>&1 to list all subgraphs and their status.

If the user already named a subgraph (name/version), confirm it exists in the list. Otherwise show the list and ask which one to diagnose. Note its status and which network it indexes — a wrong network is one of the most common root causes (see Step 5).

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.
