If your client can't find jarvis-server on PATH (GUI apps often don't inherit your shell's), use the absolute path from which jarvis-server.

Install the Homebrew binary first. The plugin adds jarvis skills and can register the already-installed jarvis-server.

/plugin marketplace add jarvis-intelligence/jarvis-index
/plugin install jarvis@jarvis

The standalone package includes the SCIP converter and both Zoekt binaries. The Homebrew formula does not install setup.sh; from a jarvis source checkout, install the optional per-language indexer for your repo:

For Maven-built Java repositories on macOS, also install a modern Bash with brew install bash, then run sh setup.sh --only bash-shim from that same source checkout. Reindex after adding an indexer. Without the matching indexer, documentSymbols and goToDefinition still work via Tree-sitter where coverage exists; findReferences, callHierarchy, and typeHierarchy return recovery guidance.

semanticSearch is registered for MCP compatibility but is excluded from the standalone distribution. It returns a Homebrew-specific unavailability error that points to the source-build steps below; lexical search and symbol search remain available.

The standalone Homebrew package excludes semantic dependencies. In a source checkout, install them with:

uv run jarvis install-semantic

Then index explicitly:

uv run jarvis index /path/to/repo --semantic

install-semantic also pre-downloads the embedding model (BAAI/bge-m3, ~4.3 GB, one time) into the shared Hugging Face cache (~/.cache/huggingface/); every indexed repo reuses it. If the download is interrupted, the next jarvis index retries it automatically.

One indexing CLI writes precomputed indexes into ~/.jarvis; one stdio runtime reads them down. The two share no other contract.

• Publishing is atomic — a reindex writes a new snapshot, then flips the current pointer via os.replace. A query reading the old snapshot keeps working; no downtime window.
• The runtime path never writes — every query opens the published snapshot read-only (mode=ro&immutable=1).
• The package graph is rebuilt, not accumulated — each reindex clears that repo's outgoing edges before recomputing.

jarvis index /path/to/your/repo            # slug defaults to the directory name
jarvis index /path/to/your/repo --slug foo # or pick one explicitly
jarvis index /path/to/your/repo --scheme MyScheme # Swift repo with an ambiguous Xcode scheme
jarvis index /path/to/your/repo --language python # force the language instead of detecting it
jarvis index /path/to/your/repo --no-scip   # skip optional SCIP enrichment; syntax baseline + Zoekt still publish
jarvis index /path/to/your/repo --scip      # re-enable SCIP enrichment (both flags persist per repo)
jarvis list
jarvis status foo
jarvis reindex foo
jarvis forget foo
jarvis watch /path/to/your/repo [--debounce 5.0]  # debounced auto-reindex on file changes (foreground)

• scip-java can't index Android/Gradle repos — its Gradle plugin keys off standard source sets that AGP replaces (scip-java#177). Detected automatically; degrades to search-only.
• Kotlin indexing requires an exact Kotlin version match — scip-kotlinc is compiled against one pinned release (currently 2.2.0). Detected automatically.
• Maven-built Java repos need bash ≥ 4.4 on macOS — brew install bash fixes it.
• Swift indexing requires scip >= v0.9.0 — older converters silently drop occurrence ranges. jarvis index refuses an older scip rather than publishing a broken index.

The source-development semantic path has additional model-prefix overrides; they have no effect in the standalone distribution.
