Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00242 | $0.03450 |
| Opus 5.5 | $0.00097 | $0.01380 |
| Sonnet 5.5 | $0.00048 | $0.00690 |
| Haiku 4.5 | $0.00024 | $0.00345 |
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.
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.

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:
- Extract the key signal: the exception type, package name, or the most distinctive phrase from the error message
- Dispatch the
vault-exploreragent with the signal as the query. - Answer returned? Apply the documented solution; update the note if you learn something new about the problem.
Readspecific files from the Sources section only if you need more depth. - "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:
- Dispatch the
vault-exploreragent with the feature keyword as the query. - Answer returned? Reuse and adapt — a proven implementation beats a fresh one every time.
Readspecific files from the Sources section for details; check thesourcesfrontmatter field for code references. - "No relevant vault notes found"? Implement it, then save the pattern so future sessions benefit.
What ships with it
60 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.

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.

parsidion is a skill published in the GitHub repository paulrobello/parsidion (10 stars, last pushed 3d ago), licensed MIT. It adds 242 tokens to every session and 3,450 once invoked, about $0.0010 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
