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 | $0.00077 | $0.03501 |
| Opus 5 | $0.00039 | $0.01750 |
| Sonnet 5 | $0.00015 | $0.00700 |
| Haiku 4.5 | $0.00008 | $0.00350 |
Grade A, and why
cold-email-outreach 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 — 375 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Cold Email Outreach
The final mile of the outbound pipeline. Takes leads from wherever the user has them, builds email sequences, loads campaigns into the user's chosen outreach tool, and launches.
Tool-agnostic: Asks the user which outreach platform they use. Defaults to Smartlead if they have MCP tools configured. Falls back to CSV export for any other tool or manual workflow.
When to Use
Use this skill when:
- User says "launch a campaign", "send outreach", "email these leads", "set up cold email"
- User has a list of leads and wants to run an outbound email campaign
- User wants to create and configure a campaign in Smartlead or another outreach tool
Supported Outreach Tools
This skill does NOT assume a specific tool. It asks first, then adapts.
| Tool | Integration | How It Works |
|---|---|---|
| Smartlead (default) | MCP tools (mcp__smartlead__*) |
Full automation: create campaign, add sequences, import leads, allocate mailboxes, configure schedule, launch |
| Instantly | CSV import | Generate CSV matching Instantly's import format, user uploads manually |
| Lemlist | CSV import | Generate CSV with Lemlist-compatible columns |
| Apollo | CSV import | Generate CSV matching Apollo sequence import format |
| Manual / Other | CSV + instructions | Export leads + emails as generic CSV, provide setup instructions |
Tool selection logic:
- Ask user in Phase 0: "Which outreach tool do you use?"
- If Smartlead → use MCP tools for full automation
- If Instantly / Lemlist / Apollo → generate tool-specific import CSV
- If Other or unknown → generate generic CSV (
email,first_name,last_name,company,title,subject,bodyper touch) and ask user for their tool's import requirements
Prerequisites
Environment Variables
For Smartlead (full automation):
SMARTLEAD_API_KEY=your_api_key_here
All Smartlead API calls go to https://server.smartlead.ai/api/v1 with ?api_key=$SMARTLEAD_API_KEY appended. Rate limit: 10 requests per 2 seconds.
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.

cold-email-outreach is a skill published in the GitHub repository gooseworks-ai/goose-skills (1,202 stars, last pushed 11d ago), licensed MIT. It adds 77 tokens to every session and 3,501 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.
Other skills, from other repositories
sequence-architect
Design a 4-6 touch outreach cadence with channels, timing, tonal arc, and branching. Use when starting a new sequence from scratch given an ICP and offer.
icebreaker
Draft 3 distinct opening messages for a specific prospect, anchored on a why-now and a why-this-person. Use when sending a high-leverage first touch where personalization is worth the time.
sequence-doctor
Audit an outreach sequence and produce a ranked fix list. Use when reply rates are low, when you want a second opinion before sending, or when rewriting a sequence from scratch.
jargon-bingo
Score sales calls, emails, or posts on a 5x5 bingo card of cliches. Mostly for fun; quietly useful for spotting jargon-heavy patterns.
prospect-twin
Build a believable persona simulation of a prospect from their LinkedIn profile, then practice outreach against them. Use when preparing for a high-stakes outreach or call, when iterating on openers, or when testing whether a pitch lands.
cringe-translator
Translate sales-jargon-laden LinkedIn messages into what the sender actually means. Mostly for fun; occasionally educational about why a message tanked.
