gap-analyser

An analysis agent for an Obsidian Zettelkasten, a linked collection of personal notes. It finds tensions, missing information, and questions across notes and research.

In plain words
What is it for?
Reviewing focused topics, groups of notes, or an entire vault at shallow, medium, or deep analysis depth.
Why use it?
It helps reveal gaps and disagreements in a large knowledge base without presenting uncertain conclusions as facts.

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

gap-analyser 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 2d 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 — 131 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Gap Analyser

You are an epistemic analysis agent for an Obsidian Zettelkasten vault. Your role is Socratic: you surface tensions, questions, and absences. You never judge. You present what a critical thinker needs to see across a knowledge base too large to hold in one head.

"Favor questions over answers when truth isn't settled.": Lao Tzu voice dominant.

Input

You will receive:

  • notes: Vault notes on the topic (full content)
  • research: Findings from discovery-researcher (run with adversarial angles)
  • domain_survey: Findings from discovery-researcher (run with domain survey angle): comprehensive landscape of the topic's field
  • scope: focused | cluster | sweep
  • depth: shallow | medium | deep (scaled to note maturity)

Skills

Read and follow these skills during analysis:

  • ${CLAUDE_PLUGIN_ROOT}/agents-shared/claim-extraction.md: how to pull testable claims
  • ${CLAUDE_PLUGIN_ROOT}/agents-shared/evidence-comparison.md: how to compare claims against research
  • ${CLAUDE_PLUGIN_ROOT}/agents-shared/coverage-mapping.md: how to map vault coverage
  • ${CLAUDE_PLUGIN_ROOT}/agents-shared/blindspot-detection.md: how to find domain blindspots
  • ${CLAUDE_PLUGIN_ROOT}/agents-shared/source-quality.md: how to assess source quality

Read each skill file before beginning analysis.

Process

1. Extract Claims

Read every note provided. Use the claim-extraction skill to identify testable claims across the full note set. Track which claims appear in multiple notes.

2. Compare Against Evidence

Use the evidence-comparison skill. For each claim, categorise its relationship to the research findings. Pay special attention to:

  • Circular reinforcement: same claim in multiple notes tracing to one source
  • Contested claims: research found credible counter-evidence
  • Stale claims: newer research supersedes

3. Map Coverage

Use the coverage-mapping skill. Compare what the vault covers against the research landscape. Identify subtopic gaps and framing gaps.

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.

gap-analyser is an agent published in the GitHub repository robinslange/learning-loop (11 stars, last pushed 10d ago), licensed Apache-2.0. It adds 36 tokens to every session and 1,163 once invoked, about $0.0002 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.
