Parallel agents conflict? Define shared tests first

Use Claude Code with a small test project and interface contracts to prepare a work plan, isolated changes and integration log through the test workflow below, then review it. Matching tools and permissions are required.

Execution environment and usage

AI / software

Claude Code

Where to operate

Claude Code in a terminal, opened in a separate test folder.

Getting started

  1. Follow the linked official setup guide; open a terminal in the test folder, run claude and sign in.
  2. Supply a small test project and interface contracts and the prompt below. Confirm the scope before allowing necessary actions.
  3. Inspect the resulting work plan, isolated changes and integration log; record anything not run or not verified.

Setup and plan requirements

Requires access to Claude Code, authorized test data and a matching runtime; file writes and shell commands must stay within approved scope. Preparation: A technical owner, isolated branches, known-answer tests and explicit resource limits are prerequisites. Requires isolated branches, fixed acceptance tests and resource limits. Parallel-agent coordination must be configured separately; a prompt does not establish it.

Prompt portability limits

Adapt the wording to another coding assistant only after separately configuring files, runtime, test tools and integrations. Renaming the tool does not establish compatibility.

Usage limitations

This workflow was not hands-on tested. Work on test copies; no automatic publishing, payment or production-data changes. Separate plans, actual results and untested areas.

適用情境 / When to use

Use Claude Code with a small test project and interface contracts to prepare a work plan, isolated changes and integration log through the test workflow below, then review it. Matching tools and permissions are required. Nicholas Carlini reports developing a C compiler with Claude agent teams, emphasizing test harnesses and integration.

步驟 / Steps

  1. A technical owner, isolated branches, known-answer tests and explicit resource limits are prerequisites.
  2. Split a small project along clear interfaces, recording assumptions and change boundaries.
  3. Run shared tests before integration and retain failures; agents must not alter acceptance rules to pass.

提示詞 / Prompt

For [small test project], propose independent work units under [interface contracts] and [time/cost limits]. Make isolated-branch changes and evaluate them with [fixed acceptance tests]. Report integration conflicts and failures without changing acceptance rules, merging or deploying.

留意事項 / Cautions

  • Do not copy unlimited loops or permission-bypass settings from experiments.
  • Passing tests cover only tested scenarios and still require human review.

來源限制 / Evidence limits

This vendor research experiment retains compatibility, efficiency and regression problems; it is not a drop-in replacement for mature compilers.

流程說明 / Workflow note

These steps and prompts are original, untested exercises by this site, not the author’s verbatim workflow. Reported results do not guarantee exercise outcomes.
