What it does
Compound is an agent skill from thoreinstein/gemini-obsidian. Use when the user wants to promote cross-project knowledge to the global Engineering/ folder, or says "promote knowledge", "compound notes", "knowledge synthesis", or "find repeated ideas across projects".
Its SKILL.md is about 450 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It works with Obsidian. The repository describes itself as: A Gemini CLI extension for interfacing with an Obsidian vault with local first RAG capabilities. The licence is ISC.
When your agent uses it
- The user wants to promote cross-project knowledge to the global Engineering/ folder
- Says promote knowledge
- Knowledge synthesis
- Find repeated ideas across projects
Example prompts
- “promote knowledge”
- “compound notes”
- “knowledge synthesis”
- “/compound”
Workflow steps
7 steps, taken from the first numbered list in SKILL.md.
- Scan project knowledge dirs — Call obsidian_list_notes with subfolder: "working".
- Semantic clustering — For each knowledge note path, call obsidian_rag_query
- Read candidates — Call obsidian_read_note on shortlisted files.
- Draft global note — Compose a new Engineering/.md with
- Show draft to user — Present the proposed note content and path before creating.
- Create on approval — Call obsidian_create_note with the approved content.
- Report cross-links — List which project knowledge notes should now add [[ConceptName]]
What it can do on your machine
Read from SKILL.md and the folder at commit 9156cba. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Compound loads about 454 tokens when it runs. Until then it costs about 54 tokens; SKILL.md has 192 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Compound Knowledge Promotion
Identify knowledge that has crystallized across multiple projects and promote it to a global Engineering/ note.
Workflow
Scan project knowledge dirs — Call
obsidian_list_noteswithsubfolder: "working". Filter results to paths matchingworking/*/knowledge/*.md.Semantic clustering — For each knowledge note path, call
obsidian_rag_querywith the note filename (without extension) as query,limit: 8. Track which notes appear in results from 2+ different projects — these are candidates.Read candidates — Call
obsidian_read_noteon shortlisted files. Look for shared definitions, patterns, or insights worth generalizing.Draft global note — Compose a new
Engineering/<ConceptName>.mdwith:- Frontmatter:
type: concept,created: <today> - Synthesized body (not copy-paste — rewrite for clarity)
## Source Notessection with[[wikilinks]]back to originating notes
- Frontmatter:
Show draft to user — Present the proposed note content and path before creating. Ask for confirmation.
Create on approval — Call
obsidian_create_notewith the approved content.Report cross-links — List which project knowledge notes should now add
[[ConceptName]]to avoid re-discovering this knowledge next time.
Arguments
Optional topic hint: /compound authentication patterns
Tips
- If
obsidian_rag_queryreturns no results, suggest running/indexfirst - If no notes appear in 2+ projects, report that and suggest manual promotion

Use when the user wants to promote cross-project knowledge to the global Engineering/ folder, or says "promote knowledge", "compound notes", "knowledge synthesis", or "find repeated ideas across projects".
When should I use Compound?
Compound fits situations like: the user wants to promote cross-project knowledge to the global Engineering/ folder; says promote knowledge; knowledge synthesis; find repeated ideas across projects.
How do I install Compound in Claude Code?
Run `npx skills add thoreinstein/gemini-obsidian --skill compound -a claude-code`. Or copy the skill folder (skills/compound in thoreinstein/gemini-obsidian) into .claude/skills/compound in your project. Claude Code loads it when a task matches its description.
How do I install Compound in Codex?
Run `npx skills add thoreinstein/gemini-obsidian --skill compound -a codex`. Or copy the skill folder (skills/compound in thoreinstein/gemini-obsidian) into .agents/skills/compound in your project. Codex loads it when a task matches its description.
Can I use Compound in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add thoreinstein/gemini-obsidian --skill compound -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/compound, .gemini/skills/compound, .github/skills/compound and .opencode/skills/compound in your project.
What does Compound need to run?
SKILL.md names no scripts, command-line tools or credentials: Compound is instructions for the agent only.
Does Compound access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Compound safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Compound use?
Compound is published under the ISC licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Compound use?
About 454 tokens (SKILL.md is roughly 1.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Compound?
