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.

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 | $0.00071 | $0.02718 |
| Opus 5.5 | $0.00028 | $0.01087 |
| Sonnet 5.5 | $0.00014 | $0.00544 |
| Haiku 4.5 | $0.00007 | $0.00272 |
Grade A, and why
cto-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 today.
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 — 258 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CTO Advisor
Technical leadership frameworks for architecture, engineering teams, technology strategy, and technical decision-making.
Keywords
CTO, chief technology officer, tech debt, technical debt, architecture, engineering metrics, DORA, team scaling, technology evaluation, build vs buy, cloud migration, platform engineering, AI/ML strategy, system design, incident response, engineering culture
Quick Start
python scripts/tech_debt_analyzer.py # Assess technical debt severity and remediation plan
python scripts/team_scaling_calculator.py # Model engineering team growth and cost
Core Responsibilities
1. Technology Strategy
Align technology investments with business priorities.
Strategy components:
- Technology vision (3-year: where the platform is going)
- Architecture roadmap (what to build, refactor, or replace)
- Innovation budget (10-20% of engineering capacity for experimentation)
- Build vs buy decisions (default: buy unless it's your core IP)
- Technical debt strategy (management, not elimination)
See references/technology_evaluation_framework.md for the full evaluation framework.
2. Engineering Team Leadership
Scale the engineering org's productivity — not individual output.
Scaling engineering:
- Hire for the next stage, not the current one
- Every 3x in team size requires a reorg
- Manager:IC ratio: 5-8 direct reports optimal
- Senior:junior ratio: at least 1:2 (invert and you'll drown in mentoring)
Culture:
- Blameless post-mortems (incidents are system failures, not people failures)
- Documentation as a first-class citizen
- Code review as mentoring, not gatekeeping
- On-call that's sustainable (not heroic)
See references/engineering_metrics.md for DORA metrics and the engineering health dashboard.
3. Architecture Governance
Create the framework for making good decisions — not making every decision yourself.
Architecture Decision Records (ADRs):
- Every significant decision gets documented: context, options, decision, consequences
- Decisions are discoverable (not buried in Slack)
- Decisions can be superseded (not permanent)
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.

cto-advisor is a skill published in the GitHub repository alirezarezvani/claude-skills (28,607 stars, last pushed yesterday), licensed MIT. It adds 71 tokens to every session and 2,718 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 2026-10-22.
