Ghcrawl Cluster Operator

ghcrawl Cluster Operator

Use this skill when operating this repo's local-first GitHub crawler and cluster browser.

Ground Rules

• Prefer read-only inspection commands first: doctor, runs, clusters, cluster-explain, threads.
• Treat refresh, sync, summarize, key-summaries, and embed as remote/API-spend commands.
• cluster is local-only but can be CPU-heavy on huge repos.
• optimize is local-only SQLite maintenance; run it after heavy sync, embedding, clustering, or close/archive sessions.
• Always pass --json for agent-readable output.
• Use --include-code only when file overlap matters; it hydrates PR file metadata and can increase DB size.

Setup Check

ghcrawl doctor --json
ghcrawl configure --json
ghcrawl runs owner/repo --limit 10 --json
ghcrawl optimize owner/repo --json

If the local store is empty or stale, pull current open GitHub data:

ghcrawl sync owner/repo --limit 200 --json
ghcrawl sync owner/repo --include-code --limit 200 --json

For a normal end-to-end update:

ghcrawl refresh owner/repo --json

Use code hydration when file evidence should affect clustering:

ghcrawl refresh owner/repo --include-code --json

LLM And Embedding Pipeline

Default clustering can run without LLM summaries. LLM summaries and embeddings enrich the cluster graph.

Useful configurations:

ghcrawl configure --summary-model gpt-5.4 --embedding-basis title_original --json
ghcrawl configure --summary-model gpt-5.4 --embedding-basis llm_key_summary --json

For structured key summaries:

ghcrawl key-summaries owner/repo --limit 200 --json
ghcrawl key-summaries owner/repo --number 12345 --json

Then refresh vectors and clusters:

ghcrawl embed owner/repo --json
ghcrawl cluster owner/repo --json

Pull A Cluster And Its Info

List clusters:

ghcrawl clusters owner/repo --min-size 2 --limit 20 --sort size --json
ghcrawl clusters owner/repo --search "cron timeout" --limit 10 --json

Explain one durable cluster:

ghcrawl cluster-explain owner/repo --id 123 --member-limit 50 --event-limit 50 --json

Inspect current durable clusters with members:

ghcrawl durable-clusters owner/repo --member-limit 25 --json
ghcrawl durable-clusters owner/repo --include-inactive --member-limit 25 --json

Pull specific issues/PRs from the local store:

ghcrawl threads owner/repo --numbers 123,456,789 --json

Open the TUI:

ghcrawl tui owner/repo

Local Maintainer Actions

Use these only when the operator asks for durable cluster edits:

ghcrawl exclude-cluster-member owner/repo --id 123 --number 456 --reason "not same root cause" --json
ghcrawl include-cluster-member owner/repo --id 123 --number 456 --reason "same root cause" --json
ghcrawl set-cluster-canonical owner/repo --id 123 --number 456 --reason "clearest report" --json
ghcrawl merge-clusters owner/repo --source 123 --target 456 --reason "same issue family" --json

After edits, re-run:

ghcrawl cluster owner/repo --json
ghcrawl cluster-explain owner/repo --id 123 --member-limit 50 --event-limit 50 --json

Local Store Maintenance

Run maintenance after large data changes:

ghcrawl optimize owner/repo --json

Without owner/repo, optimize only checkpoints, analyzes, optimizes, and vacuums the main ghcrawl SQLite database. With owner/repo, it also optimizes that repo's vector SQLite store and reports the vector .hnsw sidecar size without rebuilding it.
