The repository describes itself as: A curated list of awesome OpenAI Codex / ChatGPT plugins, skills, and resources. The 1 Codex Marketplace. See live plugins at: https://hol.org/plugins/best-codex-plugins. The licence is MIT.
When your agent uses it
- Choosing a target segment
- Validating demand
- Screening prospects
- Finding urgent buyer problems
Example prompts
- “/eighty-twenty-market-selection”
Requirements
- Compatibility (from SKILL.md): Codex, Claude Code, and other Agent Skills-compatible clients.
Workflow steps
4 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 3e1456a. 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 (its code samples are markdown).
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.
Compatibility
Codex, Claude Code, and other Agent Skills-compatible clients.
From compatibility in the SKILL.md frontmatter.
Context cost
Eighty Twenty Market Selection loads about 840 tokens when it runs. Until then it costs about 73 tokens; SKILL.md has 319 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.
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.

80/20 Market Selection
Use this skill to identify the small slice of a market most likely to respond, buy, and produce disproportionate value. It is based on 80/20 Sales and Marketing by Perry Marshall.
Source Traceability
Primary source: 80/20 Sales and Marketing, chapters 2, 3, 20, and 21.
- Chapter 2 introduces response-triggered market testing.
- Chapter 3 applies 80/20 to common sales frustrations.
- Chapter 20 covers polarized, highly responsive markets.
- Chapter 21 covers fast market research using buyer language and unanswered questions.
Workflow
1. Define The Market Choice
Capture:
- Product or offer.
- Candidate segment.
- Buyer role.
- Urgent problem.
- Current alternative.
- Proposed proof of responsiveness.
If the segment is broad, split it into narrower groups before judging it.
2. Find Responsiveness Signals
Look for proof that buyers already move:
- Search queries for the problem.
- Social posts, forums, reviews, or communities using emotional buyer language.
- Paid offers, competitors, agencies, consultants, or tools already serving the need.
- Budget, compliance pressure, deadlines, risk, or loss tied to inaction.
- Strong positive or negative reactions, not mild approval.
Do not confuse a logical problem with a responsive market. The question is whether buyers act.
3. Disqualify Weak Segments
Reject or downgrade segments when:
- They lack money or authority.
- The pain is not urgent.
- They do not believe the offer category.
- They cannot say yes without many blockers.
- The solution does not fit their current plans.
- Buyer language is vague or borrowed from the seller.
4. Pick The Testing Move
Choose the smallest action that reveals responsiveness:
- Landing page or offer smoke test.
- Direct outreach to a narrow list.
- Paid search or paid social micro-test.
- Community/listening sprint.
- Interview batch with problem-language capture.
- Waitlist, application, or hand-raise mechanism.
