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.

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 | $0.00063 | $0.05613 |
| Opus 5.5 | $0.00025 | $0.02245 |
| Sonnet 5.5 | $0.00013 | $0.01123 |
| Haiku 4.5 | $0.00006 | $0.00561 |
Grade A, and why
building-psych-explainers scanned grade A with 1 finding 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 27d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
**For an HTML transcript, curl the page and strip the tags yourself.** WebFetch runs How it starts
The opening of the file, as written. The whole thing — 359 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Building psych explainers
Each explainer is one page on a site that already exists.
Site: What that therapy word means
Repo: ~/git/what-that-therapy-word-means (GitHub rianvdm/what-that-therapy-word-means)
Live: https://therapy-words.com (custom domain on its own zone since 2026-09-04; the
canonical host in every page's tags). https://befriending-your-nervous-system..workers.dev
still serves the same files — the Worker kept its original name when the repo was renamed —
and the previous home, therapywords.elezea.com, is a 301 redirect rule on the elezea.com zone
public/
index.html landing page; one <a class="shelf-slab"> per explainer
assets/explainer.css the entire design system, shared by every page
<slug>/index.html one explainer
wrangler.jsonc assets-only Worker: no main, no assets.binding
Start by copying an existing page under public/ as the skeleton. A new page adds
markup and inline SVG. It does not add styles — if you need a style that is not in
explainer.css, add it there so every page gets it.
Order of work
- Source it. Find where the originator explains the idea in their own words —
a transcript, a talk, their own book or site — and fetch that page. Quote from it.
The best source is often a PDF transcript, and a 27-page interview yields far more
quotable wording than any summary of it. WebFetch cannot read a PDF — it saves the
binary locally and tells you where. Extract it with the macOS PDFKit recipe in
.opencode/command/extract-pdf.md, which needs no install and no network. Do not go looking forpdftotext,mutool,qpdf,gs,pypdforQuartz-for-system- python — none of them are on this machine, and building a venv to get one is a detour around a tool that already works. For an HTML transcript, curl the page and strip the tags yourself. WebFetch runs a summariser that refuses to return long verbatim passages (on TIST it answered a request for the transcript with a note about a 125-character quote limit). The raw page was 8,000 words and read straight through in one go; that is where every spoken quote on the page came from. When the originator's own words exist only behind a paywall (EMDR: Shapiro's park story is in a journal PDF that serves an HTML block page), tell that part from their organisation's own page and quote them elsewhere. Do not quote via a blog that quotes them — the wording cannot be checked. - Check the evidence. Search for the state of the research and write down what
you actually find. This goes in the footer whether it is flattering or not.
Publisher pages (ScienceDirect, Taylor & Francis, Springer, PubMed) 403 or
cookie-wall WebFetch. Get abstracts with numbers from Europe PMC instead:
curl -s "https://www.ebi.ac.uk/europepmc/webservices/rest/search?query=DOI:<doi>&format=json&resultType=core"returnsabstractText; Crossref confirms the DOI, title and authors. Guideline PDFs read through the PDFKit recipe once downloaded. - Draft the arc from the beats below.
- Build the page.
- Run all five checks. Fix what they surface. Brevity first, because every later check can be satisfied by adding words; the voice pass last, because cutting is what breaks the voice, and it is the one Rian reads for.
- Show Rian the prose before anything goes live — the page is public writing.
- Add the index entry, deploy, byte-compare live against the repo file.
What ships with it
2 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.

building-psych-explainers is a skill published in the GitHub repository rianvdm/product-ai-public (18 stars, last pushed 21d ago), licensed MIT. It adds 63 tokens to every session and 5,613 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-25.

Take any book (EPUB/PDF), produce a personalized chapter-by-chapter analysis. Each chapter is preserved in detail (The Chapter) and mirrored back to the reader's actual life (The Mirror) using brain context. The mirror observes and resonates — a friend pointing out parallels, NOT a consultant rearranging the reader's…

Analyze past exams from the same professor to surface patterns — subject weighting, recurring issue-spot traps, favored hypo types, policy-vs-doctrine mix — and forecast likely emphases for the upcoming exam. Use when the user says "what's on the exam", "analyze past exams", "predict the exam", or shares past exams.
lean-formalize
Develop and verify a mathematical proof in Lean, continue an incomplete Lean project, or audit whether it proves the original statement. Connect actual inputs to intermediate lemmas, assemble the target theorem, check its transitive axioms, and provide a reproducible handoff. Use when Lean is requested or a specific…

Explain research, papers, or technical ideas in plain English with minimal jargon, concrete analogies, and clear takeaways. Use when the user says "ELI5 this", asks for a simple explanation of a paper or research result, wants jargon removed, or asks what something technically dense actually means.
