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 | $0.14257 | $0.14257 |
| Opus 5.5 | $0.05703 | $0.05703 |
| Sonnet 5.5 | $0.02851 | $0.02851 |
| Haiku 4.5 | $0.01426 | $0.01426 |
Grade B, and why
parsidion CLAUDE.md 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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Project Overview
Parsidion is the source repository for an agent-agnostic markdown knowledge vault: skills, agents, hook scripts, search/index tools, and visualizer/MCP integrations that give coding agents persistent memory. Claude Code remains the primary installed adapter today, but the core vault tooling is runtime-agnostic.

Install model (ARC-026): The skill install differs by platform.
- macOS / Linux —
installer/skill.py:install_skill()symlinks~/.claude/skills/parsidionback to this repo (skills/parsidion/), so edits to source files are live in the installed location without a reinstall. The same applies to the visualizer's vault hooks, which can importvault_commondirectly from the repo. - Windows — symlinks require elevated privileges or a Developer-mode opt-in, so the installer falls back to
shutil.copytree. Edits underskills/are not picked up live; re-runuv run install.py --force --yesafter every source change.
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.
