social-media-kit SKILL.md skillA

This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.

social-media-kit from huytieu/cog-second-brain is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

Produce and attach native media (video teaser, GIF, card images) for every social post to maximize reach and interaction. Use whenever you post to X, LinkedIn, Reddit, or prepare HN/IndieHackers handoffs, and whenever a social-publishing step runs. A text-only social post is a draft, not a post.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Social media kit

Every social post carries a video, GIF, or image. Native media is the largest reach lever the feed algorithms give you. This skill defines the kit of assets, the visual rules that keep a campaign from looking templated, and the browser mechanics for attaching media on each platform.

## Configuration

Set these once. Scripts read them from environment variables, so nothing personal is hardcoded.

| Setting | Env var | Default |
|---|---|---|
| Signature shown bottom-right on cards | `BRAND_URL` | `yourblog.example` |
| Output folder for cards | `CARD_OUT_DIR` | `.` |
| Screenshot for the runner card | `CARD_SCREENSHOT` | unset (card skipped) |
| Quote card attribution | `QUOTE_ATTRIBUTION` | `Your Name · your role` |
| Pass / fail dot colors | `CARD_ACCENT_PASS`, `CARD_ACCENT_FAIL` | `3DD68C`, `F2555A` |
| Banner accent color | `BANNER_ACCENT` | `e13f5e` (coral, configurable) |
| Fonts | `HEADLINE_FONT`, `MONO_FONT` | macOS Helvetica Neue and Menlo, DejaVu on Linux |

Your handles, avatar and brand colors belong in your own config or prompt, never in this skill.

## Requirements

- Python 3 with Pillow (`pip install pillow`)
- ffmpeg, for teaser cuts and clips

How to install

The exact contents, by fingerprint

mdr add huytieu/cog-second-brain/social-media-kit@sha256:541e50594f64cba5

The line at the top of this page pins the label git:20261023.65f43f1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
