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.

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 →

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 | $0.00073 | $0.01713 |
| Opus 5 | $0.00036 | $0.00856 |
| Sonnet 5 | $0.00015 | $0.00343 |
| Haiku 4.5 | $0.00007 | $0.00171 |
Grade A, and why
create-x-content 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 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.
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 — 161 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Create X Content
Draft X/Twitter post variants that sound like you, not like an AI. Reads a voice guide the user has already generated (or prompts to create one), produces multiple framings of the same idea, and saves each variant as its own markdown file with frontmatter.
This is an agent-executed skill — the agent does the drafting and self-check inline. No Python script.
Quick Start
/create-x-content --brief "New open-source CLI that turns Figma files into React components. Called figma2react. Free, MIT licensed."
Or interactively:
/create-x-content
Inputs
| Flag | Required | Default |
|---|---|---|
--brief |
Yes (asked interactively if missing) | — |
--variants |
No | Skill decides based on brief richness (2–5) |
--voice-guide |
No | Resolved via chain below |
--output |
No | ./content/YYYY-MM-DD-<topic-slug>/ |
--topic |
No | Derived from brief |
Voice Guide Resolution
Resolve in this order, stop at first hit:
--voice-guide <path>flag~/.goose-skills/config.json→voice_guides.x~/.goose-skills/voice-guides/voice-x.md(default path)- Fallback prompt — no guide found. Give the user three options:
- (a) Paste a path to an existing guide
- (b) Run
/generate-voice-guide --platforms xnow to create one (recommended) - (c) Proceed with a neutral default (warn that variants will sound generic)
Never silently skip the voice guide. Generic posts are the failure mode to avoid.
Workflow
Phase 1 — Load the voice guide
Read the resolved voice guide into context. Extract, for use throughout drafting:
- Banned phrases — treat as hard blocks
- Hook patterns — sample these for variant framings
- Format rules — length ranges, line-break style, emoji policy
- Dos/don'ts — apply to every variant
- Example posts — use as calibration targets
Phase 2 — Parse the brief and decide variant count
Decide variant count by richness:
- 2 variants — one-line opinions, single-angle hot takes, simple tool mentions with no mechanism
- 3 variants — typical tool spotlights, single how-tos, observations with one clear angle
- 4 variants — multi-angle topics (a how-to + a problem-first frame + a hype frame + a mechanism breakdown)
- 5 variants — rich, mechanism-heavy content where several distinct hooks all have real substance
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.

create-x-content is a skill published in the GitHub repository gooseworks-ai/goose-skills (1,202 stars, last pushed 11d ago), licensed MIT. It adds 73 tokens to every session and 1,713 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.
