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 | $0.00086 | $0.07432 |
| Opus 5 | $0.00043 | $0.03716 |
| Sonnet 5 | $0.00017 | $0.01486 |
| Haiku 4.5 | $0.00009 | $0.00743 |
Grade A, and why
obs-memory 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 12d 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.
This is a copy
100% identical to obs-memory — 1 line differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 801 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Obsidian Agent Memory
You have access to a persistent Obsidian knowledge vault — a graph-structured memory that persists across sessions. Use it to orient yourself, look up architecture and component knowledge, and write back discoveries.
Vault Discovery
Resolve the vault path using this chain (first match wins):
- Environment variable:
$OBSIDIAN_VAULT_PATH - Agent config reference: Parse the vault path from the agent's project or global config (look for "Obsidian Knowledge Vault" section with a path like
~/Documents/SomeName/) - Default:
~/Documents/AgentMemory
Store the resolved path as $VAULT for all subsequent operations. Derive $VAULT_NAME as basename "$VAULT" for CLI calls.
Verify the vault exists by checking for $VAULT/Home.md. If the vault doesn't exist, inform the user and suggest running the init command to bootstrap a new vault from the bundled template.
Session Start — Orientation
At the start of every session, orient yourself with at most 2 operations:
Step 1: Read TODOs
CLI-first:
obsidian vault=$VAULT_NAME tasks path="todos" todo verbose
Fallback: Read the file at $VAULT/todos/Active TODOs.md.
Know what's pending, in-progress, and recently completed.
Step 2: Detect current project and read its overview
Auto-detect the project from the current working directory:
basename $(git rev-parse --show-toplevel 2>/dev/null) 2>/dev/null || basename $(pwd)
Then check if a matching project exists by listing files in $VAULT/projects/*/. Match the git repo name (or directory name) against project folder names. If a match is found, read the project overview at $VAULT/projects/{matched-name}/{matched-name}.md.
This project overview contains wikilinks to all components, patterns, architecture decisions, and domains. Do not read those linked notes yet — follow them on demand when the current task requires that context.
What NOT to read at session start
Home.md(only if you're lost and can't find the project)sessions/(only if the user references prior work)- Domain indexes (only if you need cross-project knowledge)
- Component notes (only when working on that component)
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.

obs-memory is a skill published in the GitHub repository AdamTylerLynch/obsidian-agent-memory-skills (52 stars, last pushed 6mo ago), licensed MIT. It adds 86 tokens to every session and 7,432 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to obs-memory, differing in 1 line, and is treated as a copy.
