realm-recall

realm-recall is a skill for Claude Code, Codex from blackmo18/realm. It costs 131 tokens per session (2,029 once invoked), scanned A, original, MIT.

A natural-language search tool for an Obsidian vault, a collection of linked notes, that retrieves architecture decisions, rejected alternatives, constraints, and discoveries.

In plain words
What is it for?
Use it to ask why a design was chosen, what alternatives were rejected, or which constraints and related decisions apply to a topic.
Why use it?
It lets developers recover the reasoning behind past decisions without manually searching through all project 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

realm-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 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.

How it starts

The opening of the file, as written. The whole thing — 213 lines — stays where its author put it; the contents beside it link to each section on GitHub.

realm-recall

Host invocation: Claude Code and Gemini use /realm-recall; Codex uses $realm-recall.

Ask vault anything. Get compressed context back. Optimized for ADR queries.

Syntax

/realm-recall <topic>               # NL topic, decision keyword, tag
/realm-recall <topic> --trace       # Link tree only (zero content, <10 tokens)
/realm-recall <topic> --full        # Full prose for matched nodes
/realm-recall <topic> --deps        # Include [[depends_on]] nodes (compressed)
/realm-recall <topic> --count       # Estimate token cost before pulling
/realm-recall <topic> --expand <id> # Expand one node's full prose after compressed view
/realm-recall <topic> --no-canvas   # Skip canvas expansion even if source_plan present

ADR Query Patterns

The primary reason to use realm-recall — answering questions code can't answer:

/realm-recall "why JWT"
→ decision nodes where JWT appears in title/context/rationale (~20 tokens)

/realm-recall "what was rejected for auth"
→ ADR nodes with non-empty rejected_alternatives field, #auth tag (~30 tokens)

/realm-recall "constraint on payments"
→ decision nodes with consequences field mentioning payments (~25 tokens)

/realm-recall "has anyone tried websockets"
→ searches rejected_alternatives across all ADRs for websocket mentions

/realm-recall decisions
→ all ADR nodes, compressed (~20 tokens each)

/realm-recall decisions --full
→ full prose for all ADRs including context, rejected, consequences

Canvas Lazy-Load (source_plan)

When an ADR was promoted from a realm-plan canvas, its source_plan field points to the canvas dir. realm-recall intent-maps the query to exactly one canvas section and reads only that file. Cost: ADR compressed (~20t) + one section (~80–150t). Suppress with --no-canvas.

Trigger-word table, resolution steps, and worked examples: references/canvas-expansion.md (loads only in Step 4.5, only when a loaded node has source_plan).

General Query Examples

/realm-recall auth
→ All #auth nodes → compressed view

/realm-recall "session refresh"
→ Semantic → decision/discovery nodes matching phrase

/realm-recall auth --trace
→ Auth dependency tree, no content (<10 tokens) → explore in Obsidian

/realm-recall #critical-path --count
→ "12 nodes, ~240 tokens compressed, ~1800 tokens full"

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.
