founder_mode

A command for handling experimental features that were implemented before their normal ticket and pull-request process was set up. A pull request is a proposed code change submitted for review.

In plain words
What is it for?
Use it after building an experimental feature to create the ticket, make a branch, move the commit onto it, push the branch, and open a pull request.
Why use it?
It connects an existing implementation to a Linear ticket, branch, commit, and GitHub pull request so the work can enter the team's usual workflow.

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.

Token cost

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.

Security

Grade A, and why

founder_mode 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 2d 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.

What it actually says

you're working on an experimental feature that didn't get the proper ticketing and pr stuff set up.

assuming you just made a commit, here are the next steps:

  1. get the sha of the commit you just made (if you didn't make one, read .claude/commands/commit.md and make one)

  2. read .claude/commands/linear.md - think deeply about what you just implemented, then create a linear ticket about what you just did, and put it in 'in dev' state - it should have ### headers for "problem to solve" and "proposed solution"

  3. fetch the ticket to get the recommended git branch name

  4. git checkout main

  5. git checkout -b 'BRANCHNAME'

  6. git cherry-pick 'COMMITHASH'

  7. git push -u origin 'BRANCHNAME'

  8. gh pr create --fill

  9. read '.claude/commands/describe_pr.md' and follow the instructions

Changes

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.

founder_mode is a command published in the GitHub repository jeffh/claude-plugins (12 stars, last pushed 18d ago), licensed Apache-2.0. It adds 10 tokens to every session and 217 once invoked, about $0.0001 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 2026-08-30.
