OpenViking Code Repository Search

IMPORTANT: All ov commands are terminal (shell) commands — run them via the bash tool. Execute directly — no pre-checks, no test commands. Handle errors when they occur.

How OpenViking Organizes Data

OpenViking stores content in a virtual filesystem under the viking:// namespace, similar to a local directory tree:

viking://
└── resources/
    ├── fastapi/               ← repo A
    │   ├── fastapi/
    │   │   ├── routing.py
    │   │   └── dependencies/
    │   └── tests/
    └── requests/              ← repo B
        ├── requests/
        └── tests/

Each directory has AI-generated summaries (abstract / overview). The key principle: narrow the URI scope to improve retrieval efficiency. Instead of searching all repos, lock to a specific repo or subdirectory — this reduces noise and speeds up results significantly.

Search Commands

Choose the right command based on what you're looking for:

Command	Use when	Example
ov find	You know the concept but not the exact code	"dependency injection", "rate limiting logic"
ov grep	You know the exact keyword or symbol	function name, class name, error string
ov glob	You want to enumerate files by pattern	all *.py files, all test files

# Semantic search — concept/intent based
ov find "dependency injection" --uri viking://resources/fastapi --limit 10
ov find "how tokens are refreshed" --uri viking://resources/fastapi/fastapi/security
ov find "JWT authentication" --limit 10   # across all repos

# Keyword search — exact match or regex
ov grep "verify_token" --uri viking://resources/fastapi
ov grep "class.*Session" --uri viking://resources/requests/requests

# File enumeration — by name pattern (--uri is required)
ov glob "**/*.py" --uri viking://resources/fastapi
ov glob "**/test_*.py" --uri viking://resources/fastapi/tests
ov glob "**/*.py" --uri viking://resources/   # across all repos

Narrowing scope: once you identify a relevant directory, pass it as --uri to restrict subsequent searches to that subtree — this is faster and more precise than searching the whole repo.

Read Content

# Directories: AI-generated summaries
ov abstract viking://resources/fastapi/fastapi/dependencies/   # one-line summary
ov overview viking://resources/fastapi/fastapi/dependencies/   # detailed breakdown

# Files: raw content
ov read viking://resources/fastapi/fastapi/dependencies/utils.py
ov read viking://resources/fastapi/fastapi/dependencies/utils.py --offset 100 --limit 50

abstract / overview only work on directories. read only works on files.

Browse

ov ls viking://resources/                        # list all indexed repos
ov ls viking://resources/fastapi                 # list repo top-level contents
ov tree viking://resources/fastapi               # full directory tree

Add a Repository

ov add-resource https://github.com/owner/repo --to viking://resources/ --timeout 300
ov add-resource /path/to/project --to viking://resources/ --timeout 300

--timeout is required (seconds). Use 300 (5 min) for small repos, increase for larger ones.

After submitting, run ov observer queue once and report status to user. Indexing runs in background — do not poll or wait.

Repo Size	Files	Est. Time
Small	< 100	2–5 min
Medium	100–500	5–20 min
Large	500+	20–60+ min

Remove a Repository

ov rm viking://resources/fastapi --recursive

This permanently deletes the repo and all its indexed content. Confirm with the user before running.

Error Handling

command not found: ov → Tell user: pip install openviking --upgrade --force-reinstall. Stop.

url is required / CLI_CONFIG error → Auto-create config and retry:

mkdir -p ~/.openviking && echo '{"url": "http://localhost:1933"}' > ~/.openviking/ovcli.conf

CONNECTION_ERROR / failed to connect:

• ~/.openviking/ov.conf exists → auto-start server, wait until healthy, retry:

  openviking-server --config ~/.openviking/ov.conf > /tmp/openviking.log 2>&1 &
  for i in $(seq 1 10); do ov health 2>/dev/null && break; sleep 3; done

• Does not exist → Tell user to configure ~/.openviking/ov.conf first. Stop.

More Help

For other issues or command details, run:

ov help
ov <command> --help   # e.g. ov find --help
