About

Running GitNexus Analysis

Use this skill whenever GitNexus context is stale or missing for target repositories.

Local Wrapper (Use First)

./skills/metagit-gitnexus/scripts/analyze-targets.sh [project_name]

Workflow

Analyze the current repository where the command is run.
Resolve target project repositories from .metagit.yml.
Run npx gitnexus analyze in each local repository path found.
Report per-repository success/failure and next actions.

Manual workspace graph (`.metagit.yml` → Cypher)

Promote inferred edges first (see metagit-graph-maintain skill), then ingest:

./skills/metagit-gitnexus/scripts/ingest-workspace-graph.sh -c .metagit.yml
./skills/metagit-gitnexus/scripts/ingest-workspace-graph.sh -c .metagit.yml --gitnexus-repo my-umbrella --dry-run

Manual export + MCP:

metagit config graph export -c .metagit.yml --format tool-calls --output /tmp/graph-tool-calls.json
uv run python ./skills/metagit-gitnexus/scripts/ingest_workspace_graph.py /tmp/graph-tool-calls.json
# MCP export: metagit_export_workspace_graph_cypher

Schema DDL (MetagitEntity / MetagitLink) runs once per index; pass --gitnexus-repo when the umbrella index name differs from manifest name.

GitNexus group sync (cross-index analysis)

Align workspace.projects[] repos with a GitNexus group for group impact, group query, and contract linking:

./skills/metagit-gitnexus/scripts/sync-group.sh -c .metagit.yml
metagit gitnexus group sync -c .metagit.yml --json
metagit gitnexus group sync -c .metagit.yml --group-name my-workspace --prune

MCP: metagit_gitnexus_group_sync

Prerequisites:

Each managed repo checkout exists locally and has been analyzed (gitnexus analyze).
Registry entries exist in ~/.gitnexus/registry.json for those paths.
Multi-repo workspace with workspace.projects[] in .metagit.yml.

Group paths use /; default group name is a slug of manifest name (stored under ~/.gitnexus/groups//).

After sync, use GitNexus directly:

npx gitnexus group status 
npx gitnexus group query  "authentication flow"
npx gitnexus group impact  --repo  --target

Output Contract

Return:

analyzed repositories
failures and reasons
whether graph queries are safe to run now

Safety

Skip repositories that do not exist locally.
Do not mutate repo content; analysis should be read-only indexing.
