parsidion

parsidion is a skill for Claude Code, Codex from paulrobello/parsidion. It costs 242 tokens per session (10,736 once invoked), scanned B, original, MIT.

A knowledge-management skill for an Obsidian vault, which is a folder of linked Markdown notes. It searches existing notes first, then creates structured, linked notes with metadata when needed.

In plain words
What is it for?
Use it to check prior notes, investigate errors using saved knowledge, capture new information, maintain the vault, and work with ParsidionVault or its legacy ClaudeVault location.
Why use it?
It reduces duplicate notes and keeps stored knowledge organized, searchable, connected, and marked by confidence.

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 B, and why

parsidion scanned grade B 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 2d ago.

The scan reads SKILL.md. This mod also ships 59 executable files (scripts/agent_adapter.py, scripts/ai_backend.py, scripts/antigravity_session_end_hook.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 746 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Parsidion vault - Knowledge Management System

A richly organized Obsidian vault (default ~/ParsidionVault/, with legacy ~/ClaudeVault/ fallback) that replaces built-in auto memory with structured, searchable, cross-linked knowledge.

Philosophy

  • Search before create. Always search the vault before creating a new note. Duplicate knowledge fragments rot.
  • Atomic notes. One concept per note. If a note covers two distinct ideas, split it.
  • Frontmatter is mandatory. Every note must have a valid YAML frontmatter block. No exceptions.
  • Knowledge compounds. Individual notes gain value through links. An unlinked note is a dead note.
  • Confidence matters. Tag what you know vs. what you suspect. Update confidence as understanding deepens.

Vault-First Consultation

The vault is your first stop — not your last resort. Before web search, before documentation, before experimentation, check whether the vault already holds a solution.

Debugging: Search Before You Diagnose

When you encounter an error, exception, or unexpected behavior:

  1. Extract the key signal: the exception type, package name, or the most distinctive phrase from the error message
  2. Dispatch the vault-explorer agent with the signal as the query.
  3. Answer returned? Apply the documented solution; update the note if you learn something new about the problem. Read specific files from the Sources section only if you need more depth.
  4. "No relevant vault notes found"? Diagnose, solve, then save the solution so future sessions benefit.

Implementation: Check for Prior Art

When implementing any feature, pattern, or integration:

  1. Dispatch the vault-explorer agent with the feature keyword as the query.
  2. Answer returned? Reuse and adapt — a proven implementation beats a fresh one every time. Read specific files from the Sources section for details; check the sources frontmatter field for code references.
  3. "No relevant vault notes found"? Implement it, then save the pattern so future sessions benefit.

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.
