What it does
Yes And is an agent skill from amplitude/builder-skills. Think bigger about your idea while solving the real risks. Inspired by how the best startup advisors give feedback — they find the kernel of something great, push you to see the larger version you're missing, then help you defuse the landmines between here and there.
Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: Open-source AI skills for product managers — battle-tested by PMs at Amplitude.
Example prompts
- “/yes-and”
What it can do on your machine
Read from SKILL.md and the folder at commit 51838c2. It shows what the files ask for, not the result of running them.
Tool permissions
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.
Runs code
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.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Yes And loads about 1.6k tokens when it runs. Until then it costs about 69 tokens; SKILL.md has 207 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.
Safety
Auto-check passed
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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 207 words (~1,571 tokens).
“Find the bigger idea hiding inside, then make it survivable.”
- name
- yes-and
- suggest_when
- User shares a draft, proposal, plan, or idea and wants feedback. Says "what do you think", "make this better", "build on this", "poke holes in this", "think…
