newsletter-sponsorship-finderFind newsletters relevant to a target audience/industry for sponsorship opportunities.
Newsletter Sponsorship Finder is an agent skill from gooseworks-ai/goose-skills. Find newsletters relevant to a target audience/industry for sponsorship opportunities. Discovers newsletters through web search, newsletter directories, and industry research. Returns newsletter name, author, estimated audience, topic focus, sponsorship rates (if available), and contact info.
Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including scripts (for example `scripts/search_newsletters.py` and `skill.meta.json`).
It sits in Writing & Content, covering Newsletters. It works with Substack. The repository describes itself as: Library of Growth & GTM skills + data APIs for Claude Code, Codex, Cursor to run ads, social, content, lead gen, seo and data scraping. The licence is MIT.
5 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit c650c6d. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python3pip3From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use pip3, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Newsletter Sponsorship Finder loads about 1.5k tokens when it runs. Until then it costs about 81 tokens; SKILL.md has 488 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Newsletter Sponsorship Finder fits situations like: tasks that involve Newsletters.
Run `npx skills add gooseworks-ai/goose-skills --skill newsletter-sponsorship-finder -a claude-code`. Or copy the skill folder (skills/ads/capabilities/newsletter-sponsorship-finder in gooseworks-ai/goose-skills) into .claude/skills/newsletter-sponsorship-finder in your project. Claude Code loads it when a task matches its description.
Run `npx skills add gooseworks-ai/goose-skills --skill newsletter-sponsorship-finder -a codex`. Or copy the skill folder (skills/ads/capabilities/newsletter-sponsorship-finder in gooseworks-ai/goose-skills) into .agents/skills/newsletter-sponsorship-finder in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add gooseworks-ai/goose-skills --skill newsletter-sponsorship-finder -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/newsletter-sponsorship-finder, .gemini/skills/newsletter-sponsorship-finder, .github/skills/newsletter-sponsorship-finder and .opencode/skills/newsletter-sponsorship-finder in your project.
Going by SKILL.md and its folder, Newsletter Sponsorship Finder needs Python for the scripts in its folder and the command-line tools its instructions call (python3 and pip3). Our summary lists: Python 3.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
Newsletter Sponsorship Finder is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.5k tokens (SKILL.md is roughly 6.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
