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. Each URI maps to a file or directory, e.g. viking://resources/fastapi/routing.py. 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 search Semantic search — use for concept/intent based queries "dependency injection", "how auth works"
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
ov search "dependency injection" --uri viking://resources/fastapi --limit 10
ov search "how tokens are refreshed" --uri viking://resources/fastapi/fastapi/security
ov search "JWT authentication" --limit 10          # across all repos
ov search "error handling" --limit 5 --threshold 0.7  # filter low-relevance results

# 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 (always specify --uri to scope the search)
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.

Query formulation: write specific, contextual queries rather than single keywords.

ov search "API"                                                       # too vague
ov search "REST API authentication with JWT tokens"                   # better
ov search "JWT token refresh flow" --uri viking://resources/backend   # best

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 ls viking://resources/fastapi --simple        # paths only, no metadata
ov ls viking://resources/fastapi --recursive     # list all files recursively
ov tree viking://resources/fastapi               # full directory tree (default: 3 levels deep)
ov tree viking://resources/fastapi -L 2          # limit depth to 2 levels
ov tree viking://resources/fastapi -l 200        # truncate abstract column to 200 chars
ov tree viking://resources/fastapi -L 2 -l 200   # combined: 2 levels deep, 200-char summaries

-L controls how many levels deep the tree expands. -l controls the length of the AI-generated summary per directory. Use ov tree -L 2 -l 200 as a good starting point to understand a repo's structure before diving in.

Add a Repository

ov add-resource https://github.com/owner/repo --to viking://resources/repo --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. 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 > /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.
