What it does
Indexing is an agent skill from austintgriffith/ethskills. How to read and query onchain data — events, The Graph, indexing patterns. Why you cannot just loop through blocks, and what to use instead.
Its SKILL.md is about 2.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Backend & APIs. The repository describes itself as: The missing knowledge between AI agents and production Ethereum.
When your agent uses it
- Backend & APIs work in your project
Example prompts
- “/indexing”
Requirements
- Node.js
- A credential in YOUR_KEY
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Define a schema — what entities you want to query
- Write mappings — TypeScript handlers that process events into entities
- Deploy — subgraph indexes all historical events and stays synced
What it can do on your machine
Read from SKILL.md and the folder at commit 06ea4ef. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
npm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Indexing loads about 2.6k tokens when it runs. Until then it costs about 37 tokens; SKILL.md has 699 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 699 words (~2,572 tokens).
“You try to query historical state via RPC calls. You can't cheaply read past state. eth_call reads current state. Reading state at a historical block requires an archive node (expensive, slow). For historical data, you need an indexer.”
