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 | $0.01829 | $0.01829 |
| Opus 5.5 | $0.00732 | $0.00732 |
| Sonnet 5.5 | $0.00366 | $0.00366 |
| Haiku 4.5 | $0.00183 | $0.00183 |
Grade A, and why
knowledge-manager 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 140 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md — Claude Code project contract
This file is read automatically by Claude Code when it opens the knowledge-manager repo. It tells Claude how the placeholder system works and how to edit skill, agent, and command files without breaking portability for other users.
Repository purpose
knowledge-manager is a deployment repo. End users clone it, run /knowledge-manager-setup, and the wizard substitutes their personal paths into the skill/agent/command files. The source tree in this repo must stay portable — meaning it must contain {{PLACEHOLDER}} tokens, not one specific user's hardcoded vault path.
If you hardcode /home/tofu/AI/AI_Second_Brain (or any other personal path) into a skill file, every downstream user who pulls that change is broken until they manually reset it.
Critical: Placeholder System
Every file under skills/, agents/, and commands/ is either:
- Pristine source (what lives in git) — contains placeholder tokens like
{{VAULT_PATH}}. - Substituted local copy (what the user actually uses) — tokens replaced with real values from
km-config.json, and markedgit update-index --skip-worktreeso the changes don't show up as dirty.
The 5 placeholders
| Placeholder | Replaced with | Source config field |
|---|---|---|
{{VAULT_PATH}} |
Absolute vault path, e.g. /home/user/Documents/MyVault |
storage.obsidian.vaultPath |
{{VAULT_NAME}} |
Basename of vault path, e.g. MyVault |
(derived) |
{{OBSIDIAN_CLI}} |
Path to Obsidian CLI executable, or empty | obsidianCli.path |
{{ZETTELKASTEN_ROOT}} |
Vault-relative folder, e.g. Zettelkasten |
storage.obsidian.zettelkastenRoot |
{{RESEARCH_ROOT}} |
Vault-relative folder, e.g. Research |
storage.obsidian.researchRoot |
Placeholders in source vs after setup
# IN SOURCE (what you commit):
Save the extracted note to {{VAULT_PATH}}/{{ZETTELKASTEN_ROOT}}/AI/note.md
# AFTER /knowledge-manager-setup (local user view):
Save the extracted note to /home/user/Documents/MyVault/Zettelkasten/AI/note.md
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.

knowledge-manager CLAUDE.md is an instructions file published in the GitHub repository treylom/knowledge-manager (248 stars, last pushed 6d ago), licensed MIT. It adds 1,829 tokens to every session, about $0.0073 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-01.
