ghcrawl

name	ghcrawl
description	Use the local ghcrawl CLI to inspect duplicate clusters and issue/PR summaries from the existing ghcrawl dataset, and refresh one repo only when the user explicitly asks. Use when a user wants to triage related issues or PRs, inspect semantic clusters, or run ghcrawl's staged refresh pipeline.

ghcrawl

Use ghcrawl as the machine-facing interface for local GitHub duplicate-cluster analysis.

Never read the ghcrawl SQLite database directly with sqlite3 or any other database client. If the supported CLI cannot return the needed information, report that CLI problem to the user instead of bypassing the interface.

Do not scrape the TUI. Prefer JSON CLI output.

The skill has two modes:

• Default mode: assume API credentials are absent, unavailable, or irrelevant and stay read-only on existing local data.
• API-enabled mode: only after ghcrawl doctor --json proves GitHub and OpenAI auth are configured and healthy.

In default mode, do not treat missing credentials as a problem unless the user explicitly asked for an API-backed operation or a supported read-only CLI command failed and doctor shows local setup is broken.

Even in API-enabled mode, never run sync, embed, cluster, or refresh unless the user explicitly asks for that work. Those commands can take a long time, consume paid API usage, and trigger rate limiting if used too often.

Current pipeline defaults to keep in mind:

• persistent semantic search and clustering use a vectorlite sidecar index
• the default summary model is gpt-5-mini
• the default embedding basis is title_original, so refresh does not summarize unless the user explicitly switches to title_summary
• changing summary model or embedding basis with ghcrawl configure makes the next refresh rebuild vectors and clusters
• opting into title_summary can materially improve clustering quality, but it adds OpenAI cost; on openclaw/openclaw it improved non-solo cluster membership by about 50%

Also never run close-thread or close-cluster unless the user explicitly asks you to mark a local thread or cluster closed.

When to use this skill

• The user wants related issue/PR clusters for one repo.
• The user wants to refresh local ghcrawl data before analysis.
• The user wants cluster summaries, cluster detail dumps, or nearest neighbors from a local ghcrawl database.

Command preference

Prefer the installed ghcrawl bin.

If ghcrawl is not on PATH, use:

npx ghcrawl cli ...

Do not start by running ghcrawl --help or <subcommand> --help. The documented command surface in this skill and references/protocol.md is the default source of truth. If you are actively maintaining ghcrawl itself or syntax is genuinely in doubt, command help is available through ghcrawl help <command> and ghcrawl <command> --help.

Core workflow

1. Default read-only flow

Do not run doctor on skill startup by default.

Start with local read-only commands:

Without explicit user direction to refresh data, prefer these local-only commands:

ghcrawl threads owner/repo --numbers 12345 --json
ghcrawl clusters owner/repo --min-size 10 --limit 20 --sort recent --json
ghcrawl cluster-detail owner/repo --id 123 --member-limit 20 --body-chars 280 --json
ghcrawl threads owner/repo --numbers 42,43,44 --json
ghcrawl author owner/repo --login lqquan --json
ghcrawl search owner/repo --query "download stalls" --mode hybrid --json
ghcrawl neighbors owner/repo --number 42 --limit 10 --json
ghcrawl configure --json

These operate on the existing local SQLite dataset.

Treat that stored dataset as the default source of truth for read-only analysis. Do not probe credentials, inspect env vars, or explain missing auth unless an API-backed task was requested or the supported CLI path is failing.

By default:

• threads and author hide locally closed issues/PRs
• clusters and cluster-detail hide locally closed clusters

If the user explicitly wants to inspect those records, add --include-closed.

Use threads --numbers 12345 when you need to find the cluster for one specific issue/PR number. The returned thread record includes clusterId. If it is non-null, follow with cluster-detail --id <clusterId>.

Use configure --json when you need to confirm the currently selected summary model or embedding basis before suggesting an expensive refresh.

Use threads --numbers ... when you need a batch of specific issue/PR records. Do not pay the CLI startup cost 10 times for 10 separate single-thread lookups.

Use author --login ... when you need one author's open threads and their strongest stored same-author similarity matches in one call.

If the user explicitly asks to mark a local issue/PR or cluster closed, use:

ghcrawl close-thread owner/repo --number 42 --json
ghcrawl close-cluster owner/repo --id 123 --json

If close-thread closes the last open item in a cluster, ghcrawl will automatically mark that cluster closed too.

2. Check local health only when needed

Run:

ghcrawl doctor --json

If the bin is unavailable, fall back to:

pnpm --filter ghcrawl cli doctor --json

Only do this when:

• the user explicitly wants an API-backed operation such as refresh, sync, embed, or cluster
• or a read-only request failed and you need to know whether the local install/config/auth state is broken

Interpret the result like this:

• If GitHub/OpenAI auth is missing or unhealthy, stay in read-only mode.
• If GitHub/OpenAI auth is healthy, API-backed operations are available, but still require explicit user direction.

If doctor is unhealthy but the user asked only for read-only inspection, say that API-backed refresh is unavailable and continue with read-only CLI commands when possible.

3. If the CLI is unavailable or misbehaving

Use one supported fallback path before giving up:

pnpm --filter ghcrawl cli ...

If a documented ghcrawl command still fails, hangs, or returns unusable output through the supported CLI path, stop and report that to the user. Do not inspect tables, schema, or rows with sqlite3, pragma, or ad hoc SQL.

4. Refresh local data only when explicitly requested

Only if the user explicitly asks to refresh or rebuild data, and doctor says auth is healthy, use:

ghcrawl refresh owner/repo

This runs, in fixed order:

1. GitHub sync/reconcile
2. summarize-if-needed
3. embed refresh
4. cluster rebuild

You may skip steps only when the user explicitly wants that or the freshness state makes it unnecessary:

ghcrawl refresh owner/repo --no-sync
ghcrawl refresh owner/repo --no-cluster

Do not decide on your own to run cluster just because it is local-only. It is still long-running and should be treated as an explicit user-directed operation.

5. List clusters

Use:

ghcrawl clusters owner/repo --min-size 10 --limit 20 --sort recent --json

This returns:

• repo stats
• freshness state
• cluster summaries

6. Inspect one cluster

Use:

ghcrawl cluster-detail owner/repo --id 123 --member-limit 20 --body-chars 280 --json

This returns:

• the selected cluster summary
• each member thread
• a body snippet
• stored summary fields when present

7. Optional deeper inspection

Use search or neighbors as needed:

ghcrawl search owner/repo --query "download stalls" --mode hybrid --json
ghcrawl neighbors owner/repo --number 42 --limit 10 --json

Output rules

• Report the repo name and whether you refreshed data in this run.
• When listing clusters, include:
  • cluster id
  • representative number and kind
  • display title
  • total size
  • PR count
  • issue count
  • latest updated time
• When naming a cluster in prose, use this shape:
  • Cluster <clusterId> (#<representativeNumber> representative <issue|pr>)
  • example: Cluster 23945 (#42035 representative issue)
• When drilling into a cluster, include clickable GitHub links for each issue/PR if you mention them.
• Prefer concise summaries over dumping raw JSON.
• If freshness is stale, say that explicitly:
  • embeddings outdated
  • clusters outdated
• If you stayed read-only because doctor was not healthy or the user did not explicitly request a refresh, say that explicitly.
