The idea in one minute

Start with meaning, then move to detail.

This lesson explains Contributing as part of Hermes internals and extension points. You will learn what it does, when it matters, and the smallest safe test that proves it works.

If you are new

If you are new, do not memorize names. Focus on three questions: what problem does this solve, what access does it need, and how can you verify the result?

For hands-on use

For practice, inspect the first example, identify its effects, run it on test data, and compare the result with the source claim.

For specialists

For advanced readers, inspect Contribution Priorities, Common contribution paths, Development Setup, then verify failure modes and version compatibility.

What do you need first?

Know Python, Git, and basic project structure before changing code.

What will you know?

A clear outcome before you read.

  • Understand Contributing without assumed prior knowledge.
  • Separate the source description from what still needs testing in your environment.
  • Read the first command and identify its inputs and outputs before copying it.

Examples from the official page

Copy only after you understand the effect.

curl -fsSL https://hermes-agent.nousresearch.com/install.sh | bash cd "${HERMES_HOME:-$HOME/.hermes}/hermes-agent" # Add dev/test extras on top of the standard install. uv pip install -e ".[all,dev]" # Optional: browser tools / docs site dependencies. npm install
git checkout -b fix/description scripts/run_tests.sh
scripts/dev-sandbox.sh python -m hermes_cli.main scripts/dev-sandbox.sh --persistent python -m hermes_cli.main desktop # state survives restarts, but lives in the worktree :)
Try it now

Read the first command and identify its inputs and outputs before copying it.

Match every command to your installed Hermes version, review the files and accounts it can reach, and use non-sensitive data for the first test. If this explanation differs from the source, the official source wins.

Knowledge check

Three decisions before completion.

1. What is the source of truth when “Contributing” changes?
2. What is the best way to apply this lesson?
3. What should happen before a step can modify files or an external account?
