Skill for Claude Code

Written for Claude Code: argument-hint in frontmatter. Also seen: mentions CLAUDE.md.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

wiki scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

The opening of the file, as written. The whole thing — 543 lines — stays where its author put it; the contents beside it link to each section on GitHub.

LLM Wiki

Persistent, compounding knowledge base inside an Obsidian vault.

Operations

/llm-wiki:wiki init my-topic
/llm-wiki:wiki ingest ~/ObsidianVault/03-Resources/my-topic/raw/article.md
/llm-wiki:wiki ingest https://example.com/article
/llm-wiki:wiki query "What is X?"
/llm-wiki:wiki lint

Active Wiki Detection

Walk up from cwd looking for a directory containing both CLAUDE.md and a wiki/ subfolder.

  1. Start at cwd. Check if CLAUDE.md and wiki/ exist in the current directory.
  2. If found → that directory is the active wiki root. Read CLAUDE.md for schema.
  3. If not found → move to parent directory and repeat until filesystem root.
  4. If no wiki found anywhere in the path, prompt the user:

    "Which wiki should I use?" List available wikis by running: ls -d ~/ObsidianVault/03-Resources/*/wiki 2>/dev/null and presenting the parent directory names.


qmd Availability

Reference paths used throughout this skill:

QMD="env -u BUN_INSTALL ${CLAUDE_PLUGIN_DATA}/node_modules/.bin/qmd"
MARP="${CLAUDE_PLUGIN_DATA}/node_modules/.bin/marp"

Check: Test if "${CLAUDE_PLUGIN_DATA}/node_modules/.bin/qmd" exists and is executable via Bash: test -x "${CLAUDE_PLUGIN_DATA}/node_modules/.bin/qmd".

Important: Always invoke qmd via env -u BUN_INSTALL to force Node.js runtime. If BUN_INSTALL is set in the environment, qmd runs under Bun, which uses a SQLite build without extension loading support and cannot load sqlite-vec.

  • If present: use it for query and embed operations. ALWAYS use the full path — never bare qmd.
  • If absent: fall back to reading wiki/index.md manually and grepping wiki files.

init <name>

Create a new wiki scaffold under the Obsidian vault.

Steps

  1. Check if wiki already exists: If ~/ObsidianVault/03-Resources/<name>/ exists, abort with: "Wiki '' already exists at ~/ObsidianVault/03-Resources//. Use wiki remove <name> first, or choose a different name."

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
