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 | $0.00048 | $0.04216 |
| Opus 5 | $0.00024 | $0.02108 |
| Sonnet 5 | $0.00010 | $0.00843 |
| Haiku 4.5 | $0.00005 | $0.00422 |
Grade A, and why
social-preview scanned grade A with 0 findings 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 9d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 489 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Social Preview
Generate Open Graph social preview images (1280x640px) for GitHub repositories. The social preview is the single highest-leverage visual asset when repos are shared on Twitter, LinkedIn, Slack, and Discord.
When to Use
- New public repo needs a social preview before sharing
- Rebranding a project (new colors, name change, logo update)
- Major release or launch -- refresh the preview to reflect the milestone
- Before marketing pushes (LinkedIn posts, Twitter threads, blog features)
- Audit existing repos to catch missing or outdated social previews
Usage
/social-preview generate [repo-path] # Create OG image from repo context
/social-preview audit [repo-path] # Check if social preview is set, dimensions correct
Default repo-path is the current working directory if omitted.
Procedure: Generate
Execute each step in order. Do not skip steps.
Step 0: Parse Command
Expect: /social-preview {mode} [repo-path]
Extract mode (generate or audit). If missing or invalid:
Error: Invalid or missing mode.
Usage:
/social-preview generate [repo-path]
/social-preview audit [repo-path]
STOP.
Validate repo-path is a directory containing .git. Default to cwd if omitted.
Step 1: Scan Repo for Context
Gather:
- Project name -- from
package.jsonname,Cargo.toml[package] name,pyproject.tomlname, or directory name - Description/tagline -- from package.json description, repo description, or ask user
- Primary language -- from file extensions, package manager files, or
gh repo view --json primaryLanguage - Logo/icon -- check for
logo.png,logo.svg,icon.png,icon.svg,.github/logo.png,assets/logo.*,branding/logo.* - Git remote --
git remote get-url originto extract owner/repo - Existing social preview --
gh api repos/{owner}/{repo}to check current state
Step 2: Select Template
Present template options to the user:
- Dark (recommended) -- Dark background (#0d1117 or #141414), light text. Highest contrast, best performance on most feeds.
- Light -- Light background (#fafbfc), dark text. Matches certain brand aesthetics.
- Minimal -- Just project name + tagline, no decoration. Clean and typographic.
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.
