Goose Skills is a library of workflows and data APIs that lets coding agents handle growth and go-to-market work such as advertising, social media, content, SEO, lead generation, and customer research. It is intended for teams using Claude Code, Cursor, Codex, and similar agents. The catalogue entries are its reusable skills.
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Rogue Agent · line 103 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00087 | $0.02070 |
| Opus 5 | $0.00044 | $0.01035 |
| Sonnet 5 | $0.00017 | $0.00414 |
| Haiku 4.5 | $0.00009 | $0.00207 |
Grade A, and why
generate-voice-guide 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 — 183 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Generate Voice Guide
Turn a real person's past posts into a structured voice guide that other skills can use to draft in-voice content. Produces one guide per platform (X, LinkedIn, or both) with persona, dos/don'ts, banned phrases, hook patterns, format rules, and example posts.
This is an agent-executed skill — the agent handles scraping, analysis, drafting, and iteration via the tools available in the session. No bundled Python script.
When to use
- A user wants to build a personal voice guide for social content
- Another skill (e.g.
create-x-content,create-linkedin-content,social-kit) needs a voice guide and one doesn't exist - The user wants to mimic someone else's public voice (for ghostwriting, parody, or study)
When NOT to use: For analysing a company's blog/landing-page voice, use brand-voice-extractor instead. That's for corporate marketing voice; this one is for individual social voice.
Quick Start
Interactive:
/generate-voice-guide
Args mode:
/generate-voice-guide --profile @GooseworksAI --platforms x,linkedin --output ~/.goose-skills/voice-guides
Discovery Questions (front-loaded)
Ask these up front if not supplied via flags:
- Whose voice? "Paste an X/Twitter handle (e.g.
@GooseworksAI), a LinkedIn profile URL, or both. You can mimic your own voice or someone else's." - Which platforms? "Generate a voice guide for X, LinkedIn, or both?"
- How many posts to scan? "Default: 50 X posts / 25 LinkedIn posts. Higher = more signal, more tokens, slower."
- Save location? "Default:
~/.goose-skills/voice-guides/voice-{x,linkedin}.md. Ok to use that, or prefer a different path?"
Workflow
Phase 1 — Scrape past posts
For X:
- Use Apify actor
apidojo/twitter-user-tweets-scraper(or whichever X scraper is available in the session) keyed to the handle. - Fetch the target count (default 50). Exclude replies, retweets, and quote tweets unless the user specifies otherwise — we want original voice.
- Requires
APIFY_API_TOKENenv var. If missing, surface a clear error with the setup link.
What ships with it
1 file 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.

generate-voice-guide is a skill published in the GitHub repository gooseworks-ai/goose-skills (1,202 stars, last pushed 11d ago), licensed MIT. It adds 87 tokens to every session and 2,070 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
