Discover Product is an agent skill from rand/cc-polymath. Automatically discover product management skills when working with product management, roadmap, user stories, prioritization, metrics, or product strategy. Activates for product development tasks.
Its SKILL.md is about 500 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: Designed for Claude Code. Compatible with any agent supporting the Agent Skills format.
It sits in Product & Project Management, covering User stories, Prioritization frameworks and Product strategy. The repository describes itself as: Claude Code skills and workflows, optimized for context-efficiency and skill quality. Skills ranging from cloud infrastructure to design to advanced maths. The licence is MIT.
4 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit baa2df1. 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.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
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.
Designed for Claude Code. Compatible with any agent supporting the Agent Skills format.
From compatibility in the SKILL.md frontmatter.
Discover Product loads about 499 tokens when it runs. Until then it costs about 53 tokens; SKILL.md has 173 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); files beside SKILL.md are not scanned.

Run `npx skills add rand/cc-polymath --skill discover-product -a claude-code`. Or copy the skill folder (skills/discover-product in rand/cc-polymath) into .claude/skills/discover-product in your project. Claude Code loads it when a task matches its description.
Run `npx skills add rand/cc-polymath --skill discover-product -a codex`. Or copy the skill folder (skills/discover-product in rand/cc-polymath) into .agents/skills/discover-product 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 rand/cc-polymath --skill discover-product -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/discover-product, .gemini/skills/discover-product, .github/skills/discover-product and .opencode/skills/discover-product in your project.
SKILL.md names no scripts, command-line tools or credentials: Discover Product is instructions for the agent only. Compatibility (from SKILL.md): Designed for Claude Code. Compatible with any agent supporting the Agent Skills format..
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. Review the folder before installing.
Discover Product is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 499 tokens (SKILL.md is roughly 2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
