Most Claude Code conversation lives in developer territory: build an app, refactor a module, debug a stack trace. The thing nobody is talking about is what Claude Code can do for the rest of consulting work, particularly sustainability work, where the same patterns repeat across clients and the cost of regenerating them every session quietly compounds.
This is a small, growing hub of Claude Code skills built for sustainability consultants, ESG communicators, and circular economy practitioners. Open source. Free to use. Designed to cut both consulting time and AI compute cost (the math behind that is in How Claude Code Skills Cut AI Energy Use).
What’s here
- Five skills, each a self-contained directory that drops into your Claude Code skills folder.
- Installable in two minutes: clone or copy a folder, set any required env vars, done.
- Built for real work, not demos. Each skill came out of consulting workflows I run weekly.
- Open on GitHub at github.com/Borjablm/claude-skills with downloadable ZIPs and full source.
The skills
Programmatic charts, stat cards, branded title images, and free-license stock photo search. Replaces AI image generation for structured visuals at roughly 97% less cost and energy. Five chart types (bar, stacked, time series, grouped, donut) plus HTML-to-image rendering. Includes a setup wizard that walks you through your brand colors and fonts.
End-to-end SEO content pipeline. Five-stage workflow: brief and competitor analysis, deep research (web and video), structured outline planning, adversarial writer/editor draft, polished delivery with SEO meta. Brand voice and calibration examples. Built for sustainability content but works for any domain.
Comprehensive Google Search Console audit framework. Striking-distance keywords, content decay detection, cannibalization analysis, mobile/desktop gap, dead-page finder, brand vs non-brand health ratio. The seven-point methodology I use for client SEO reviews.
Publish articles to WordPress via the REST API. Multi-site support so one CLI handles every brand you maintain. Featured image upload, category and tag resolution, draft or live publish. Natural follow-up to blog-post-writer.
Prepare technical field inspections for sustainability certifications, subsidy reconciliations, supplier audits, and similar regulatory site visits. Locates approved scope documents, reconciles invoices against the approved scope per period, generates a printable inspection checklist plus a gaps report. Generalised from a real public-subsidy inspection workflow.
The roadmap is shaped around what comes up in client work: a CSRD reporting helper, a material flow analysis assistant, an ESG data review tool. If there’s a sustainability workflow you’d want as a skill, open an issue on GitHub or drop me a note.
How to install
Each skill is a self-contained directory. There are two ways to bring one into your Claude Code setup:
.claude/skills/ folder or your user-level ~/.claude/skills/. Easiest if you want to track updates.
Each skill has its own README with setup steps (env vars, dependencies, brand customisation). Most need only Python 3.9+ and one or two free API keys for the parts that touch external services.
Project-scoped vs user-scoped: Drop a skill into your-project/.claude/skills/ if it’s tied to a specific project (different brand voice per client, for example). Drop it into ~/.claude/skills/ if it’s a tool you want available across all your work. You can do both, with project-level skills taking precedence.
Why these skills exist
Most consultants I know use Claude in a way that quietly wastes compute. Brand voice pasted into every chat. Methodology framework re-explained on every call. Chart Python regenerated from scratch every time an article needs a visual. The skills system in Claude Code was built for exactly this kind of repetition, but the documentation aims at developers, so the consulting-side use cases stay invisible.
I wrote about the architecture and the math in How Claude Code Skills Cut AI Energy Use and the broader sustainability-AI tension in Claude Code for research workflows in circular economy and sustainability. These five skills are the proof points behind those pieces.
They’re also useful in their own right, regardless of whether you read the articles. The image-generation savings alone, for anyone publishing more than a handful of articles a year, pay for themselves in time and cost on day one.

Stay in the loop
If you want a heads-up when a new skill lands, or when the planned Sustainability Reporting Pack (CSRD prep, material flow analysis, ESG data review) is ready, drop me a note. I keep a short list and ship infrequently.
For issues, ideas, or pull requests, the GitHub repo is the right place. Stars also help others find this if you’ve found it useful.
