claude-skills is a large collection of reusable skills, commands, plugins, and supporting resources for coding agents across engineering, business, research, compliance, and productivity work. It is used by people who want agents such as Claude Code, Codex, Gemini CLI, or Cursor to follow specialized workflows. The catalogue contains selected skills and settings from the collection.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Agent Snooping · line 1 Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.Fix: Remove all code or instructions that list or read other skills' files or directories. Skills should operate independently; cross-skill access is a privilege escalation.
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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00084 | $0.02067 |
| Opus 5.5 | $0.00034 | $0.00827 |
| Sonnet 5.5 | $0.00017 | $0.00413 |
| Haiku 4.5 | $0.00008 | $0.00207 |
Grade A, and why
cpo-advisor 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.
How it starts
The opening of the file, as written. The whole thing — 201 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CPO Advisor
Strategic product leadership. Vision, portfolio, PMF, org design. Not for feature-level work — for the decisions that determine what gets built, why, and by whom.
Keywords
CPO, chief product officer, product strategy, product vision, product-market fit, PMF, portfolio management, product org, roadmap strategy, product metrics, north star metric, retention curve, product trio, team topologies, Jobs to be Done, category design, product positioning, board product reporting, invest-maintain-kill, BCG matrix, switching costs, network effects
Quick Start
Score Your Product-Market Fit
python scripts/pmf_scorer.py
Multi-dimensional PMF score across retention, engagement, satisfaction, and growth.
Analyze Your Product Portfolio
python scripts/portfolio_analyzer.py
BCG matrix classification, investment recommendations, portfolio health score.
The CPO's Core Responsibilities
The CPO owns three things. Everything else is delegation.
| Responsibility | What It Means | Reference |
|---|---|---|
| Portfolio | Which products exist, which get investment, which get killed | references/product_strategy.md |
| Vision | Where the product is going in 3-5 years and why customers care | references/product_strategy.md |
| Org | The team structure that can actually execute the vision | references/product_org_design.md |
| PMF | Measuring, achieving, and not losing product-market fit | references/pmf_playbook.md |
| Metrics | North star → leading → lagging hierarchy, board reporting | This file |
Diagnostic Questions
These questions expose whether you have a strategy or a list.
Portfolio:
- Which product is the dog? Are you killing it or lying to yourself?
- If you had to cut 30% of your portfolio tomorrow, what stays?
- What's your portfolio's combined D30 retention? Is it trending up?
PMF:
- What's your retention curve for your best cohort?
- What % of users would be "very disappointed" if your product disappeared?
- Is organic growth happening without you pushing it?
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

cpo-advisor is a skill published in the GitHub repository alirezarezvani/claude-skills (28,852 stars, last pushed yesterday), licensed MIT. It adds 84 tokens to every session and 2,067 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-09-03.
