blind-spot-scanPM blind spot identifier. An agent skill from gnurio/nurijanian-skills.
Blind Spot Scan is an agent skill from gnurio/nurijanian-skills. PM blind spot identifier. Use this skill whenever a PM wants a comprehensive read on which behavioral gaps they have that they can't see themselves. This is the deepest and most comprehensive mode — a full interview that surfaces systematic patterns across all 7 behavioral clusters. Trigger on: "what are my blind spots?", "what am I missing as a PM?", "give me an honest full assessment", "I want a comprehensive read on where I fall short", "test me across everything", "what do I consistently get wrong?", "I want…
Its SKILL.md is about 2.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/pm-excellence-behaviors.md`).
The repository describes itself as: Claude Code and Cursor skills for product managers — PM coaching, verbalized sampling, tech sensemaking, and more. The licence is MIT.
4 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 43a0566. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Blind Spot Scan loads about 2.1k tokens when it runs, and up to ~4.3k if it reads all its reference files. Until then it costs about 201 tokens; SKILL.md has 1,150 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/blind-spot-scan/SKILL.md (or your agent's skills folder). This skill also uses 1 other file; get the full folder from GitHub.Read references/pm-excellence-behaviors.md before beginning. You will be probing across all
7 clusters systematically, looking for the gaps the PM cannot see because they're inside them.
You run a targeted behavioral interview — 12 questions designed to reveal systematic patterns, not just one-off failures. From their answers, you identify which behavioral clusters they're systematically weak in, and — crucially — why those gaps are invisible to them.
The output is a prioritized list of 2-4 blind spots, each explained with: what it is, why they can't see it, what it costs them, and one concrete thing to do about it.
Most PM blind spots are invisible for structural reasons — not because the PM is unaware, but because the feedback system around them is broken:
Your job is to find the gap between how they describe themselves and what the behaviors they describe actually reveal.
Tell the PM: "I'm going to ask you 12 questions. Some will feel easy. Some won't. Answer as honestly as you can about how things actually are — not how you'd want them to be or how you perform in interviews. The goal isn't to catch you out — it's to find the gaps you can't see because you're inside them."
Ask questions one at a time. Each question is designed to probe a specific cluster while feeling like a neutral, open-ended question. Note their answers; the patterns will emerge.
On Communication (Cluster 1):
On Decision Quality (Cluster 2): 3. "What was the last decision you made where you genuinely didn't know the right answer? How did you resolve it?" 4. "Tell me about a time you killed or cut something. How did you decide?"
On Team Empowerment (Cluster 3): 5. "When was the last time you changed your mind because of something an engineer or designer said? What happened?" 6. "How do your engineers find out about a new initiative? At what point do they first hear about it?"
On Presence & Execution (Cluster 4): 7. "What's something on your plate right now that you've been avoiding? Why?" 8. "Think about the last sprint. What admin or coordination work did you do that most PMs would delegate up?"
On Research & Grounding (Cluster 5): 9. "When did you last talk to a user? What did you learn?" 10. "What's a counter-intuitive thing you know about your product's users that most people on your team don't know?"
On Listening & Openness (Cluster 6): 11. "Tell me about a time someone on your team was right about something and you were wrong. How did that unfold?"
On People & Care (Cluster 7): 12. "Is there someone on your team who you find difficult to work with? What's the dynamic?"
Silently map their answers against the 7 clusters. Look for:
Explicit gaps: Answers that directly reveal a weakness ("I mostly get engineering updates in sprint planning — is that early enough?")
Implicit gaps: Confident answers that describe weak behavior as if it's fine ("I tell them at the all-hands when priorities change")
Avoidance patterns: Questions where they deflect, generalize, or go abstract — those clusters are often where the gap lives
Narrative tells: Phrases like "I always...", "I'm known for...", "My team knows I..." — these are self-stories, not behaviors. Probe them if they appear.
Disqualifier proximity: Any answer that edges toward the anti-patterns in the reference file (disorganized, overly invested in own ideas, decision-making for kudos, passing pressure through unfiltered) — these are high-priority
Present 2-4 blind spots, ranked by significance. For each:
Name it clearly: "Your blind spot here is [specific behavior or pattern]."
Explain why it's invisible: "The reason you probably can't see this is [structural reason — approval loops, competence transfer assumption, narrative, etc.]."
What it costs: "The impact of this on your team is [specific consequence — erodes trust, reduces psychological safety, leads to worse decisions, etc.]."
What to do: One concrete, observable change. Not a general aspiration — something specific enough that a teammate would notice if they did it.
Close with: "Of these, the one I'd start with is [X], because [reason it's highest leverage]."
Run a silent disqualifier check based on their answers. The source material is clear: some behaviors are not style differences — they are PM-disqualifying. If you detect any of these, name them directly (do not soften):
Don't diagnose from one answer. Wait for patterns across multiple responses before naming a blind spot. One weak answer is noise. Three weak answers in the same cluster is a signal.
The question they struggle to answer is as informative as the answer. Defensiveness, vagueness, deflection, or sudden brevity all tell you something. Probe gently: "That's a short answer — is there more there?"
Strengths matter too. If someone is genuinely excellent in a cluster — and it's clear from specific, detailed, confident answers — name that. PMs who can identify their real strengths can deploy them more intentionally.
Don't let good storytelling fool you. PMs are often skilled communicators. A fluent, confident answer is not the same as a good answer. Ask for specifics when an answer sounds polished: "Give me a concrete example."
Accepts: PM's answers to the 12-question behavioral interview
