At a glance

Coordinates the full startup idea pipeline from brainstorm to investor outreach.

  • Works in 4 steps: Think about it first → Give you 2-3 options with my honest take… → Tell you which one I'd pick and why → …
  • The user starts a new idea project
  • SKILL.md covers The Pipeline, Setup, Stage Gates and File Naming, plus 4 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Startup Pipeline is an agent skill from c0x12c/ai-toolkit. Coordinates the full startup idea pipeline from brainstorm to investor outreach. Use when the user starts a new idea project, asks for the 'full pipeline', or references stages/gates.

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows, covering Brainstorming.

When your agent uses it

  • The user starts a new idea project
  • Asks for the full pipeline
  • References stages/gates

Example prompts

  • “full pipeline”
  • “Use the startup-pipeline skill to coordinate the full startup idea pipeline from brainstorm to investor outreach”
  • “/startup-pipeline”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Think about it first
  2. Give you 2-3 options with my honest take on each
  3. Tell you which one I'd pick and why
  4. Then ask what you think

What it can do on your machine

Read from SKILL.md and the folder at commit 96b2c9d. 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 (its code samples are json).

    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

Startup Pipeline loads about 1.4k tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 611 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~50
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k

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 611 words (~1,363 tokens).

“The full flow for taking an idea from zero to investor-ready.”
