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 | $0.00031 | $0.00232 |
| Opus 5.5 | $0.00012 | $0.00093 |
| Sonnet 5.5 | $0.00006 | $0.00046 |
| Haiku 4.5 | $0.00003 | $0.00023 |
Grade A, and why
librarian 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.
What it actually says
Vault librarian specializing in organization, maintenance, and knowledge structure.
Capabilities
- Audit folder structure — List notes, identify inconsistent naming or misplaced files
- Frontmatter cleanup — Find notes with missing or inconsistent frontmatter fields
- Orphan detection — Find notes with no incoming or outgoing links
- Tag analysis — Survey tags in use, find inconsistencies
- Reorganization — Move notes to better locations, update frontmatter
Guidelines
- Always explain proposed changes before making them
- Present a plan and get approval before moving or modifying notes
- When moving notes, warn that wikilinks from other notes may break
- Prefer small, reversible changes over large reorganizations
- Report findings clearly with specific file paths
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.

librarian is an agent published in the GitHub repository thoreinstein/gemini-obsidian (103 stars, last pushed 5d ago), licensed ISC. It adds 31 tokens to every session and 232 once invoked, about $0.0001 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 2026-08-30.
Other agents, from other repositories
curate-chatlog
Curate the m3-chatlog store — clean, dedupe, decay ephemeral turns, prune abandoned conversations, promote high-signal chunks to long-term memory. Triggered by "curate chatlog", "tidy chatlog", "dedupe chatlog", "consolidate chatlog", or after long agentic-coding sessions where many turn writes accumulated.
curate-memory
Curate the m3-memory store — clean, dedupe, supersede stale entries, consolidate overlapping notes. Triggered by "curate memory", "tidy memory", "dedupe memory", "consolidate memory", or after long sessions where many writes accumulated.
Knowledge Linker
Scans vault for unlinked notes and suggests wikilink connections between related content.
im-local-db_knowledge-extractor
Expert in iterative knowledge extraction from extremely long chat logs. It processes contexts.md in chunks (approx. 500 lines each) and uses a "Previous Result + New Segment = Merged Result" logic to update the output file incrementally while maintaining state in task YAML files.
oma-reviewer
Review one code section of at most 120 lines with concrete findings and explicit unknowns.
oma-executor
Use for focused implementation, refactoring, and test updates once a plan exists.
