What is LLM-Wiki AGENTS.md?

Repository instructions for an Obsidian knowledge vault, where notes are linked and organized as a personal reference system.

Managing notes, using the vault’s search and writing commands, following Markdown conventions, and adding links and metadata consistently.

They explain which local rules and command instructions agents must follow when reading, finding, or writing vault content.

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.

Model	Per session	Once invoked
Fable 5.1	$0.03809	$0.03809
Opus 5.5	$0.01524	$0.01524
Sonnet 5.5	$0.00762	$0.00762
Haiku 4.5	$0.00381	$0.00381

Security

Grade A, and why

LLM-Wiki AGENTS.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 2mo 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.

Obsidian Second Brain - Codex CLI Operating Manual

Local vault overrides: also follow _CLAUDE.md for folder conventions and Markdown authoring rules. In particular, ._trash&cache/ is reserved for temporary stitching/cache files and soft trash, and Mermaid diagrams in new Markdown should default to the forest theme with compact, whole-graph layouts.

This vault runs the obsidian-second-brain skill. The skill ships a set of commands: each one is a multi-step instruction file that you (the Codex agent) should follow when the user's request matches its trigger phrase.

How to operate

Read _CLAUDE.md in the vault root, if it exists, to learn the user's vault conventions (folder map, daily note format, naming).
When the user's request matches a trigger in the tables below, read the matching file under .codex/commands/<name>.md and follow its instructions step by step.
Treat the AI-first vault rule (.codex/references/ai-first-rules.md) as non-negotiable for every note you write: ## For future Claude preamble, rich frontmatter (type, date, tags, ai-first: true), [[wikilinks]] for every person/project/concept, recency markers per external claim, sources verbatim, confidence levels where applicable.
Do not invent commands. If no command matches, ask the user what they want or fall back to plain natural-language help.

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.
