At a glance

Surface the user's unknown unknowns before work starts. An agent skill from Neeeophytee/finding-unknowns-skills.

  • Works in 4 steps: Ask (or infer from context) two things:… → Explore the relevant territory yourself:… → Report back in four sections → …
  • The user is entering an unfamiliar codebase area
  • SKILL.md covers Steps and Guardrails
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Blindspot Pass is an agent skill from Neeeophytee/finding-unknowns-skills. Surface the user's unknown unknowns before work starts. Use when the user is entering an unfamiliar codebase area, an unfamiliar domain (design, video, infra), or explicitly asks for a "blindspot pass" or to find their "unknown unknowns."

Its SKILL.md is about 480 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: 14 installable skills for Claude Code, OpenAI Codex, and Hermes: find unknowns, clarify requirements, manage context, test assumptions, and verify bug fixes with regression… The licence is MIT.

When your agent uses it

  • The user is entering an unfamiliar codebase area
  • An unfamiliar domain (design
  • Explicitly asks for a blindspot pass
  • Find their unknown unknowns

Example prompts

  • “blindspot pass”
  • “unknown unknowns.”
  • “/blindspot-pass”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Ask (or infer from context) two things: what they're trying to do, and what their experience level is with this specific area. Their…
  2. Explore the relevant territory yourself: the module, its history, its conventions, prior art in the repo, and (if the domain is external)…
  3. Report back in four sections
  4. End with a rewritten version of their original request that incorporates what you found, so they can see the difference between their map…

What it can do on your machine

Read from SKILL.md and the folder at commit ca5696a. It shows what the files ask for, not the result of running them.

  • Tool permissions

    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.

  • Runs code

    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.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Blindspot Pass loads about 482 tokens when it runs. Until then it costs about 63 tokens; SKILL.md has 261 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~63
When it runs · the whole SKILL.md, loaded when a task matches
~482

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.

Safety

Auto-check passed

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.

description
Surface the user's unknown unknowns before work starts. Use when the user is entering an unfamiliar codebase area, an unfamiliar domain (design, video, infra), or explicitly asks for a "blindspot pass" or to find their "unknown unknowns."

Blindspot pass

The user is about to work in territory they don't know well. Your job is not to do the task yet. Your job is to show them what they don't know they don't know, so their next prompt is better.

Steps

  1. Ask (or infer from context) two things: what they're trying to do, and what their experience level is with this specific area. Their starting point changes everything.
  2. Explore the relevant territory yourself: the module, its history, its conventions, prior art in the repo, and (if the domain is external) what practitioners consider table stakes.
  3. Report back in four sections:
    • Landmines — the mistakes someone new here typically makes, and any repo-specific potholes (deprecated paths, misleading names, half-migrated patterns).
    • Hidden context — decisions already made that constrain the work (why the code is shaped this way, invariants that must hold).
    • What good looks like — 2-3 examples of the pattern done well, from this repo or elsewhere, so they can calibrate quality.
    • Questions you should be asking — the 3-5 questions an expert would ask before starting, with your best guess at each answer.
  4. End with a rewritten version of their original request that incorporates what you found, so they can see the difference between their map and the territory.

Guardrails

  • Do not start implementing. This skill ends at understanding.
  • Prioritize unknowns that would change the architecture or the approach over trivia.
  • If the area turns out to be simpler than the user feared, say so plainly. "You have no significant blindspots here" is a valid and valuable result.
