blindspot

A review that looks for missing assumptions, viewpoints, and dimensions in an idea, plan, decision, or problem framing. It examines what your current way of thinking leaves outside the picture.

In plain words
What is it for?
Use it to inspect product ideas, technical plans, decisions, and problem definitions for missing information or unexamined ways of looking at them.
Why use it?
It helps expose gaps before you commit to a direction, without trying to decide whether the idea is good or bad. This can reveal overlooked risks and perspectives.

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

blindspot 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.

Blindspot — Gap Analysis for Ideas and Thinking

You are running a blindspot audit: a structured analysis that surfaces what's missing from both the idea itself and the thinking behind it. Your role is not to evaluate whether the idea is good or bad — it is to map what's outside the current frame: unexplored assumptions, absent perspectives, unexamined dimensions, and cognitive patterns that may be shaping what gets seen and what doesn't.

The user invoked this with: $ARGUMENTS


Phase 1: Intake & Readiness

Assess whether $ARGUMENTS gives you something to audit. The bar is low — you need: (1) something to examine (an idea, plan, decision, problem framing, or question), and (2) enough context to understand the domain and what the user is trying to do. Vague or early-stage input is fine; even an undeveloped idea has a frame that can be audited.

If the input is too thin (no discernible idea, domain, or direction): Use AskUserQuestion to ask 1–2 targeted clarifying questions. Only ask what's actually missing:

  1. What are you thinking about — what's the idea, decision, or question you want to audit?
  2. What's the decision or outcome at stake, if any?

If the input is ready: proceed directly.

Once you have enough context, synthesize a Subject Statement — 1 sentence stating exactly what's being audited. Use AskUserQuestion to present it and ask the user to confirm it accurately captures what they want audited. Wait for explicit confirmation before proceeding. If they correct or refine it, update accordingly.


Phase 2: Research (Optional, Targeted)

Determine whether external grounding would surface gaps that analysis alone would miss: competitive context, analogous situations, domain base rates, known failure modes, or relevant precedents the user may not have considered.

If yes: run 2–3 targeted WebSearch / WebFetch queries. Surface relevant findings in a brief paragraph before analysis begins. Focus on:

  • How similar ideas have played out in analogous contexts
  • Known blind spots or failure patterns in this domain
  • External factors (market, regulatory, competitive) that frequently go unexamined in this type of decision

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.

blindspot is a command published in the GitHub repository nicoladevera/thinking-stack (2 stars, last pushed 4mo ago), licensed MIT. It adds 14 tokens to every session and 1,982 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 2026-08-31.
