Claude Code Skill for exploring Obsidian vaults as a knowledge graph
SaferSkills independently audited unobsidian (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

A skill for parsing Obsidian-style markdown files and exploring the knowledge graph. Works without Obsidian installed or running.
Requires Python 3.10+, a local vault directory, and an agent that can read local files and run Python. Install the dependencies into the same Python environment used for the commands below:
python -m pip install -r "${CLAUDE_SKILL_DIR}/requirements.txt"If the skill was supplied through a connector, locate its bundled scripts first. ${CLAUDE_SKILL_DIR} refers to a local installed skill directory; it is not a remote URL. A text-only chat or connector without local script access cannot run these commands. Ask for the vault path if it was not provided.
All commands take --vault as the path to the vault directory. Graph commands default to adjacency text; --format d3 returns JSON. Tag search, path resolution, and visualization status return JSON. Runtime errors are JSON on stderr with a nonzero exit status; invalid command arguments use argparse errors.
python "${CLAUDE_SKILL_DIR}/scripts/get_graph.py" --vault "/path/to/vault" --format d3Parses supported vault files and builds a knowledge graph. Default output is compressed adjacency format (one node per line, #prefix for tags, quoted if name contains spaces). Use --format d3 for D3.js compatible JSON.
python "${CLAUDE_SKILL_DIR}/scripts/get_neighbors.py" --vault "/path/to/vault" --node "MyNote" --depth 2 --format d3--node: Node ID (omit .md, retain .canvas/.base, or use #tagname for tags)--depth: BFS depth (default: 1, max: 3)--format: Output format (default: adjacency — compressed text, d3 also supported)Traversal is bidirectional. Output retains every original directed link between nodes within the requested radius, including multiple relationship types. For backlinks, select links whose target is the requested node; incoming and outgoing neighbors are both included in the returned graph.
python "${CLAUDE_SKILL_DIR}/scripts/search_by_tag.py" --vault "/path/to/vault" --tag "project"Supports nested tags. Either project or #project also matches #project/frontend.
python "${CLAUDE_SKILL_DIR}/scripts/resolve_filepath.py" --vault "/path/to/vault" --file-id "ProjectA"python "${CLAUDE_SKILL_DIR}/scripts/visualize_graph.py" --vault "/path/to/vault" --no-openRenders the full vault graph as an interactive D3.js force-directed HTML file and opens it in a browser. --output sets the output path (default: <vault>/graph.html), --no-open disables auto-open. The HTML loads D3.js from d3js.org and requires network access to render. It contains vault filenames, tags, and relationships; do not publish it without permission.
