gaps

A note-review tool that examines a knowledge vault for missing evidence, weak claims, unanswered questions, and opposing views.

In plain words
What is it for?
Use it to review one topic, automatically choose an unexamined topic, or scan the main topic groups in a vault at a chosen depth.
Why use it?
It helps reveal where your notes are incomplete or too confident, instead of letting gaps remain hidden as the vault grows.

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

gaps 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.

Gaps: Epistemic Gap Analysis

Overview

The vault grows by accumulation. /gaps shakes the cage. It surfaces tensions, questions absences, and flags thin ice. The truth doesn't need to defend itself: weak beliefs get questioned, strong beliefs get stress-tested.

When to Use

  • /gaps "topic": focused analysis on a specific topic
  • /gaps: auto-picks the densest unchallenged cluster in the vault
  • /gaps --sweep: runs across all major domain clusters

Parameters

Parse from the invocation. All have defaults.

Parameter Options Default
topic any string auto-pick if absent
depth shallow / medium / deep scales to note maturity
sweep flag off
dry-run flag off

Depth auto-scaling:

  • Permanent notes → deep
  • Fleeting notes → medium
  • Inbox notes → shallow
  • Mixed maturity → use the highest

Provenance

This skill emits provenance events for pipeline observability. Run each Bash command silently.

At session start (after scope identified):

node "${CLAUDE_PLUGIN_ROOT}/scripts/provenance-emit.js" '{"agent":"gaps","skill":"gaps","action":"session-start","intent":"TOPIC","config":{"depth":"DEPTH"}}'

At session end:

node "${CLAUDE_PLUGIN_ROOT}/scripts/provenance-emit.js" '{"agent":"gaps","skill":"gaps","action":"session-end","notes_analysed":N,"counterpoints_created":N,"rewrites":N,"thin_ice":N,"tensions":N,"blindspots":N}'

Per-note tracking is handled automatically by the PostToolUse hook.

Process

Step -1: Parameter Resolution

No arguments (/gaps): Run auto-pick immediately (find the densest unchallenged cluster — see Step 0). After presenting results, mention the alternatives in one line:

Analysed [cluster]. Alternatives: /gaps "topic" for a specific domain, /gaps --sweep across all clusters, --depth shallow|medium|deep to override maturity scaling.

Topic provided (/gaps "topic"): Proceed immediately. Depth auto-scales to note maturity.

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.

gaps is a skill published in the GitHub repository robinslange/learning-loop (11 stars, last pushed 11d ago), licensed Apache-2.0. It adds 94 tokens to every session and 2,914 once invoked, about $0.0005 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.
