Jack CC
Jack CC's work was selected for the XERJ Corpus Hub, the open reference memory AI coding agents search before they write code. When an agent meets the same problem, it gets this implementation back as a worked example, with the author and the repository attached.
Totals across every corpus @JackCC703 appears in; a commit selected for two corpora counts once. Files and lines count the selected commits; each corpus indexes the whole repository at its pinned commit.
What an agent can do with the erigon corpus
erigontech/erigon: Ethereum implementation on the efficiency frontier
- Look up how erigon implements ethereum, blockchain, with answers cited to file and line.
- Reuse a worked example: the commit “cl/merkle_tree, cl/cltypes/solid: round merkleize depth up for non-po…” (7 files · Go).
- Answer from erigon's real Go source instead of memory (Cryptography, TLS and secrets).
- How does erigon implement ethereum?
- What does cl do in erigon?
Search the GitHub repository erigontech/erigon with XERJ (https://hub.xerj.org/corpus/erigontech--erigon). Run these in a shell, in order, and check each result before the next: 1. xerj --help (success: it prints usage). If xerj is missing: curl -fsSL https://xerj.org/get | sh 2. git clone https://github.com/erigontech/erigon erigon && git -C erigon checkout fbee0540d60ed2b32408c5d1944259e42f4a8d95 3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data 4. xerj autoindex ./erigon --url http://127.0.0.1:9200 --prefix erigon --progress plain 5. xerj autoindex map --url http://127.0.0.1:9200 Then answer my question from the indexed files and cite the ax_path of every hit.
