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.

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 | $0.00071 | $0.01905 |
| Opus 5 | $0.00036 | $0.00953 |
| Sonnet 5 | $0.00014 | $0.00381 |
| Haiku 4.5 | $0.00007 | $0.00191 |
Grade A, and why
campaign-brief-generator 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 — 219 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Campaign Brief Generator
Pure reasoning skill. Takes a campaign goal, ICP, and product context — and produces a complete, actionable campaign brief a small team can actually execute.
Built for: Founders doing their own marketing. First marketing hires. GTM teams without a dedicated strategist. The output should be opinionated and specific, not a generic template.
When to Use
- "Help me plan a campaign for [launch / feature / segment]"
- "We're targeting [ICP], what channels and content should we run?"
- "I need a 30-day campaign plan"
- "We're launching [product/feature] — help me plan the GTM"
- "Write me a campaign brief for [goal]"
Phase 0: Intake
Ask all questions in one go, grouped cleanly. This is a fast skill — don't make it feel like a form.
Campaign Context
- Goal — What does success look like in 30/60/90 days? (e.g., "50 signups from developer audience", "10 demos booked with Series B startups", "3 media mentions")
- Trigger — What's prompting this campaign? (product launch, new feature, new segment, funding, competitive threat, slow quarter)
- Timeline — How long should the campaign run? When should it start?
Audience
- ICP — Who exactly are you targeting? (Title, company type, stage, geography)
- Where do they hang out? — Channels they actively use (LinkedIn, Slack communities, specific newsletters, Twitter/X, etc.)
- What's their current pain? — The specific problem your product solves for them right now
Product & Positioning
- What are you promoting? — Specific product, feature, or offer (free trial, case study, webinar, etc.)
- Core value prop — In one sentence: what do you do and why does it matter?
- Social proof available — Customer logos, case study metrics, review quotes, press mentions
- What are you NOT — Key competitor or alternative you want to differentiate from
Constraints
- Team size — Who's executing this? (founder only, 1 marketer, SDR+marketing, etc.)
- Budget — Rough range for paid/sponsored channels (or "zero — organic only")
- Existing assets — What do you already have? (blog posts, case studies, demo video, email list)
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.
