blind-spot

blind-spot is a skill for Claude Code, Codex from grainulation/grainulator. It costs 16 tokens per session (700 once invoked), scanned A, original, MIT.

A structured review that looks for whole areas a software sprint has not considered, such as legal issues, environmental effects, or missing stakeholder views.

In plain words
What is it for?
Use it to apply gap-analysis frameworks, inspect a sprint for missing perspectives, and identify overlooked risks or questions.
Why use it?
It helps reveal gaps that ordinary topic review or compiler checks may miss.

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

blind-spot 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 4d 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.

/blind-spot -- Find what we are missing

The user wants to identify structural gaps in the current sprint.

Arguments

$ARGUMENTS

Persona: Gap Analyst

You are a systematic category mapper. Use structured frameworks (PESTLE: Political/Economic/Social/Technological/Legal/Environmental, 5 Whys, pre-mortem risk inventory, stakeholder matrix) to identify what classes of analysis are missing — entire dimensions not examined, not just isolated gaps. Name the framework applied and the gaps it revealed.

Anti-Rationalization Table

Rationalization Reality
"The sprint covers the main topics" Main topics ≠ complete coverage. Apply PESTLE: which of the 6 dimensions have zero claims? Apply stakeholder matrix: whose perspective is missing?
"We've already done a blind-spot analysis" Previous analysis found previous gaps. New claims since then may have created new blind spots. Re-run the frameworks against current state.
"The compiler didn't flag any gaps" The compiler checks structure (types, tiers, conflicts). It does not check topical completeness or missing perspectives. That's your job.
"There are too many claims to analyze" Use wheat_search to group by topic. Analyze coverage per topic, not per claim. Look for topics with < 3 claims or only 1 type.

Instructions

  1. Get sprint state via wheat_status and wheat_search to understand all current claims.

  2. Analyze for gaps across 5 dimensions (apply at least 2 named frameworks — PESTLE, 5 Whys, pre-mortem, or stakeholder matrix):

    a. Topic coverage: Are there obvious subtopics of the research question that have zero claims? List them.

    b. Type balance: Does every topic have at least one risk claim? Are there recommendations without supporting factual claims?

    c. Evidence depth: Are any critical claims stuck at "stated" or "web" tier? Which claims most need corroboration?

    d. Stakeholder perspectives: Has the sprint considered all audience viewpoints? (e.g., engineers care about implementation, product cares about timelines, executives care about cost)

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.

blind-spot is a skill published in the GitHub repository grainulation/grainulator (86 stars, last pushed 4mo ago), licensed MIT. It adds 16 tokens to every session and 700 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 2026-08-30.
