recall

A search workflow for finding related information in an Obsidian vault, a folder of linked Markdown notes. It searches by meaning and follows connections between notes to add context.

In plain words
What is it for?
Use it to search the vault for a topic, inspect the most relevant notes, find their connections, and identify highly connected notes.
Why use it?
It helps retrieve useful knowledge from a large vault when exact keywords alone may miss related notes.

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.

Security

Grade A, and why

recall 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 3d 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.

Semantic Knowledge Retrieval

You are tasked with retrieving relevant knowledge from the Obsidian vault using multi-layer semantic search.

Use Local Brain Search for all semantic search operations. Spreading activation mode recommended for synthesis queries.

Scripts:

# Static search (fast, exact matches)
resources/local-brain-search/run_search.sh "query" --limit 10 --json

# Spreading activation search (follows graph connections)
resources/local-brain-search/run_search.sh "query" --mode spreading --limit 10 --json

# Find connections
resources/local-brain-search/run_connections.sh "Note Name" --json

# Find hubs
resources/local-brain-search/run_connections.sh --hubs --json

Search Query

$ARGUMENTS

Instructions

  1. First Layer - Initial Search:

    • Use spreading activation for better context:
      resources/local-brain-search/run_search.sh "$ARGUMENTS" --mode spreading --limit 5 --json
      
    • Use Read tool to read the full content of the top 2 results
  2. Second Layer - Direct Associations:

    • For the top result from layer 1, get connections:
      resources/local-brain-search/run_connections.sh "Top Result Note" --json
      
    • Use Read tool to read the full content of the top 2 connected notes
  3. Third Layer - Extended Network:

    • For additional context, check hub notes and bridges:
      resources/local-brain-search/run_connections.sh --hubs --json
      
    • This reveals deeper conceptual connections

Output Format

Present the findings in this structured format:

# Knowledge Recall: [Query Topic]

## Layer 1: Direct Matches
[List notes found with similarity/activation scores and key excerpts]

## Layer 2: First-Degree Associations
[List connected notes with their relationships and excerpts]

## Layer 3: Extended Network
[Show hub notes and bridge connections]

## Key Insights
[Synthesize the main themes and connections discovered]

## Relevant Content
[Include the most pertinent excerpts from the retrieved notes]

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.

recall is a skill published in the GitHub repository Abilityai/cornelius (104 stars, last pushed 10d ago), licensed MIT. It adds 21 tokens to every session and 751 once invoked, about $0.0001 per session on Opus 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.
