Colophon for this issue

How this issue was made

Source

github.com/PostHog/skills, branch main, last pushed 9 August 2026.

Licence

MIT — the text of every chapter is reproduced unmodified, frontmatter included, under the upstream licence.

Discovery

200 chapters found by walking the repository tree for SKILL.md, not by matching a directory convention. 5 distinct layouts observed: skills/omnibus/*/SKILL.md, skills/posthog/all/skills/*/SKILL.md, skills/posthog/error-tracking/skills/*/SKILL.md, skills/posthog/feature-flags/skills/*/SKILL.md, skills/posthog/integration/skills/*/SKILL.md.

Issue colours

Resolved from the awesome-design-md registry — hue 38°, chroma 0.190. Two accent tones are generated per issue and each is proven against its own ground before it ships: a single accent that passes AA on both light and dark paper is arithmetically impossible.

Typefaces

Display: IBM Plex Sans Variable is not a face we ship; the reader's own choice is used.
Body: IBM Plex Sans Variable is not a face we ship; the reader's own choice is used.
Mono: Source Code Pro is not a face we ship; the reader's own choice is used.

We never load a typeface at request time from a third-party origin, so a brand face we do not already self-host is substituted rather than fetched.

Heading repairs

1 repair applied to this chapter so the document has one h1 and no skipped levels:

Shifted “5 headings” from h1 to h2 so the chapter title is the only h1.

Spec compliance

40 editorial notes across 40 of 200 chapters. They are printed in the margin of each chapter rather than as errors here.

Signals Scout Replay Vision — 1 note
Integration JavaScript Node — 1 note
Integration JavaScript Web — 1 note
Integration Nuxt 3 6 — 1 note
Omnibus Instrument Error Tracking — 1 note
Error Tracking Android — 1 note
Error Tracking Angular — 1 note
Error Tracking Flutter — 1 note
Error Tracking Go — 1 note
Error Tracking Hono — 1 note

and 30 more.

Images

Images inside a chapter come from the upstream repository. Where the author gave no alternative text we mark the image decorative rather than inventing a description — a plausible caption we made up is worse than none for the reader who depends on it.

Marketplace

A plugin manifest is published at .claude-plugin/marketplace.json by PostHog, declaring 5 plugins. It is read for editorial metadata only — never as the skill index, which is always the repository tree.

Signal

Install counts come from skills.sh. They measure downloads, not quality, and an unranked repository is not an unread one.

Agent surfaces

The whole issue is available as one markdown document at /PostHog/skills.md, and each chapter at its own .md URL.

Publication

Set by Skills Docs from the source repository. Body text is Literata at the reader’s chosen size and measure; code is Geist Mono. Nothing on this page was written by us except this paragraph.
