recall

recall is a skill for Claude Code from tuan3w/obsidian-vault-agent. It costs 88 tokens per session (2,480 once invoked), scanned A, original, MIT.

A review system based on retrieval practice, where you try to remember information before seeing the answer, and spaced repetition, where reviews return over time. It uses notes from a knowledge vault to create interactive sessions.

In plain words
What is it for?
Use it for quizzes, review sessions, resurfacing older notes, inbox triage, and discovering connections between topics.
Why use it?
It helps prevent notes from being forgotten after you read them. It also brings older material back for active recall instead of passive rereading.

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 10d 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 — 287 lines — stays where its author put it; the contents beside it link to each section on GitHub.

<Use_When>

  • User wants a review session ("what should I review?", "quiz me", "recall practice")
  • User wants to resurface notes they haven't seen in a while
  • User wants to triage their inbox
  • User wants to discover connections across domains
  • User asks "what do I remember about X?"
  • Periodic knowledge maintenance (daily, weekly reviews) </Use_When>

<Do_Not_Use_When>

  • User wants to deeply process a specific note (use /process)
  • User wants vault structure analysis (use /vault-graph)
  • User wants to synthesize across a cluster (use /synthesize)
  • User is actively reading or adding a new source note </Do_Not_Use_When>

<Execution_Policy>

  • INTERACTIVE — never skip ahead. Each card requires the user to respond before the answer is shown. The friction IS the learning.
  • Never show note content before the user attempts recall
  • Prefer notes with updated_date older than 14 days (spacing effect)
  • MUST interleave domains — draw from at least 3 different topic folders
  • Use MCP tools (search_notes, get_frontmatter) when available; fall back to Grep/Glob
  • Session size: default 5 retrieval cards, 2 inbox items, 1 surprise connection (adjust to user's argument if provided)
  • After each reveal, offer to update the note if it's stale </Execution_Policy>

Stage 1: BUILD THE QUEUE

1a. Retrieval Practice Cards (default 3–5)

Candidate selection using MCP:

search_notes(query="processing_status: processed OR processing_status: evergreen", limit=50)
search_notes(query="type: term OR type: note", limit=50)

Or fall back to Grep:

Grep(pattern="processing_status: (processed|evergreen)", path="notes/", glob="*.md")
Grep(pattern="^type: (term|note)$", path="notes/", glob="*.md")

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.
