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 | $0.00426 | $0.00426 |
| Opus 5 | $0.00213 | $0.00213 |
| Sonnet 5 | $0.00085 | $0.00085 |
| Haiku 4.5 | $0.00043 | $0.00043 |
Grade A, and why
llm-kasten CLAUDE.md scanned grade A with 0 findings 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 11d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
kasten
LLM-powered CLI knowledge base manager. Markdown files with YAML frontmatter as source of truth, SQLite for fast search/indexing.
Project structure
src/kasten/— main package (src layout)tests/— pytest test suite (76 tests)- Entry points:
kastenandkas(alias)
Commands
pip install -e ".[dev]" # Install in dev mode
python -m pytest tests/ -v # Run tests
kasten init <path> # Create vault (--agents claude|agents|gemini|copilot|all)
kasten sync # Sync files -> DB
kasten repair # Full rebuild + fix links + promote + indexes
kasten search <query> # Full-text search
kasten note list --json # JSON output for LLM agents
Architecture
- File-first: .md files are truth, SQLite is rebuildable cache
- Single visible dir:
knowledge/at repo root,.kasten/hidden - Dual output: Every command supports --json for LLM agent consumption
- FTS5: SQLite FTS5 for search, porter stemming + unicode + BM25 ranking
- Sync: mtime + SHA-256 change detection, BEGIN IMMEDIATE transactions
- Links: [[wiki-links]] parsed, resolved, backlinks computed
- Agent docs: Auto-injects into CLAUDE.md, AGENTS.md, GEMINI.md, copilot-instructions.md
Key conventions
- All frontmatter uses
yaml.safe_load/ Pydantic v2 for validation - Enums serialize via
model_dump(mode="json") - UTF-8-sig encoding for reading (handles BOM)
- Slug IDs preserve underscores (used by index pages)
- Vault path properties:
vault.notes_dir,vault.index_dir,vault.knowledge_dir - Per-tag index pages only generated for tags with 3+ notes
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.

llm-kasten CLAUDE.md is an instructions file published in the GitHub repository jordan-gibbs/llm-kasten (5 stars, last pushed 1mo ago), licensed MIT.
