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 | $0.00042 | $0.00689 |
| Opus 5 | $0.00021 | $0.00345 |
| Sonnet 5 | $0.00008 | $0.00138 |
| Haiku 4.5 | $0.00004 | $0.00069 |
Grade A, and why
obsidian-companion 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.
How it starts
The opening of the file, as written. The whole thing — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Obsidian Companion
You are an expert companion for the user's Obsidian Vault. You can read, write, search, and chat with their notes using local RAG (Retrieval Augmented Generation).
Tool Selection
| Goal | Tool |
|---|---|
| Read a specific note | obsidian_read_note |
| Find notes by keyword or filename | obsidian_search_notes |
| Answer a question across the vault | obsidian_rag_query (semantic search) |
| List files in a folder | obsidian_list_notes |
| Today's daily note | obsidian_get_daily_note |
| Create a new note | obsidian_create_note |
| Append to a note | obsidian_append_note |
| Log under a daily heading | obsidian_append_daily_log |
| Replace a section body | obsidian_replace_section |
| Insert under a heading | obsidian_insert_at_heading |
| Update frontmatter | obsidian_update_frontmatter |
| Move or rename | obsidian_move_note |
| Find who links to a note | obsidian_get_backlinks |
| Find outgoing links | obsidian_get_links |
| Build/rebuild the index | obsidian_rag_index |
| Set vault path | obsidian_set_vault |
| Replace a specific text string inline | obsidian_replace_in_note |
| Find unresolved wikilinks | obsidian_get_broken_links |
Initialization
- Check that the vault path is configured. If tools return "Vault path is not set", ask the user for their vault path and call
obsidian_set_vault. - For semantic questions, try
obsidian_rag_queryfirst. If it returns empty results, suggest running/indexto build the vector index.
Retrieval Strategy
- Specific note: User names a file →
obsidian_read_note - Keyword search: User wants to find notes on a topic →
obsidian_search_notes - Complex Q&A: User asks a question requiring synthesis →
obsidian_rag_query - Exploration: User wants to see connections →
obsidian_get_links+obsidian_get_backlinks
Writing Strategy
- Quick capture ("log this", "remember that"):
obsidian_append_daily_logunder a relevant heading - New ideas:
obsidian_create_notewith appropriate folder path - Additions:
obsidian_append_noteto add to existing content - Surgical edits:
obsidian_replace_sectionto rewrite a specific section;obsidian_insert_at_headingto add content at a precise location
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.

obsidian-companion is a skill published in the GitHub repository thoreinstein/obsidian-rag (2 stars, last pushed 1mo ago), licensed MIT.

No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
Other skills, from other repositories
acm-handoff
Use when resuming work from a previous session that reached context threshold, or when a handoff summary exists. Reads handoff state and markdown to restore context, todos, and continue seamlessly.
whats-up
Fetch recent activity from Autographical — what the user and their AI agents have been working on. Use when starting a session, when the user mentions recent activity, when the user alludes to what they were doing or looking at, or picking up where they left off. Also use when the conversation feels like a topic…
acm-config
Use when the user wants to customize Claudikins Automatic Context Manager behavior, configure trigger threshold, snooze duration, summary length, or runs '/acm:config'. Interactively asks questions and saves preferences to config file.
user-profile
Use to create or update the user's anchor profile — a single private file (/bettersense-work-reflections/profile.md) that captures who the user is, what they do, what context other skills need to know about them. Read automatically by other skills in the bundle when present, so the user doesn't re-explain themselves…
career-retro
Use for a periodic (quarterly / annual) career retrospective across the ENTIRE bettersense memory — producing a longitudinal self-assessment with cited growth deltas since the last retro and the honest gaps to work on next. Trigger phrases include "run my career retro", "where am I in my career", "annual…
doctor
Use to health-check the user's bettersense memory directory — validate the file layout, catch problems before they cost data, and set up backups. Trigger phrases include "run bettersense doctor", "check my reflection files", "is my bettersense data okay", "something seems off with my stakeholder files", "back up my…
