al-folio CLAUDE.md is an instructions file for Claude Code from alshedivat/al-folio. It costs 1,233 tokens per session, scanned A, original, MIT.

A detailed Claude Code development guide for al-folio, a Jekyll website starter whose features are supplied by separate plugins. It explains the daily development loop, local server commands, architecture references, and test gates.

In plain words
What is it for?
Use it to install dependencies, serve or build the site, run integration and visual tests, and find the architecture, ownership, and configuration documentation relevant to a change.
Why use it?
It gives agents the commands and ownership rules needed to build and test the site without duplicating plugin code or ignoring the project’s boundaries.

Token cost

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.

Security

Grade A, and why

al-folio CLAUDE.md 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 8d 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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

`docker compose up -d` bind-mounts the repo to `/srv/jekyll` and runs `bin/entry_point.sh`, which serves with `--force_polling --destination /tmp/_site`. The build output deliberately goes to **container-local `/tmp/_sit

How it starts

The opening of the file, as written. The whole thing — 49 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

@AGENTS.md

AGENTS.md (imported above) is the authoritative agent entry point: change routing, the stop sign for gem-owned paths, the three silent failure modes, and the validated command set. Keep it short and ecosystem-neutral. Cross-repo architecture — the wrapper/tag/gem delegation table, feature gating, the v1 config contract, local overrides — lives in docs/ARCHITECTURE.md; area-to-gem ownership lives in docs/BOUNDARIES.md.

Read those three before editing anything. Everything below is Claude-specific or longer-form operational detail that does not belong in the short entry point. Do not restate facts from those files here — link to them.

Daily dev loop

bundle install                                # ruby gems
bundle exec jekyll serve                      # dev server → http://localhost:4000/al-folio/  (NOTE baseurl)
bundle exec jekyll build --baseurl /al-folio  # production-style build to _site/
bash test/integration_distill.sh              # run ONE integration test (any of the seven in test/)
npm run test:visual:update                    # refresh playwright snapshots after intentional UI change
bundle exec al-folio upgrade apply --safe     # deterministic codemods (font-weight-* → font-*, remote→local URLs)
bundle exec al-folio upgrade overrides diff <path>    # then `overrides accept <path>` to acknowledge an override

Optional toolchains

  • Jupyter posts. bin/setup-python-deps installs only jupyter and nbconvert (via pip --user --break-system-packages) for jekyll-jupyter-notebook. It does not read requirements.txt. Missing jupyter-nbconvert is warn-and-continue; notebook rendering is skipped.
  • Everything else Python. requirements.txt is the fuller list and must be installed separately (python3 -m pip install -r requirements.txt): rendercv[full] for CV rendering, scholarly for bin/update_scholar_citations.py, plus nbconvert and pyyaml.
  • Responsive images. imagemagick.enabled: true needs ImageMagick convert on PATH.
  • Manual deploy. bin/deploy is the manual gh-pages build + purgecss + force-push path; CI normally deploys. purgecss is not a devDependency — install it with npm install -g purgecss.

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.
