How to work safely when many Claude Code and Codex agents share this one checkout at once.

What it does

Concurrent Agents is an agent skill from BuilderIO/agent-native. How to work safely when many Claude Code and Codex agents share this one checkout at once. Use before editing any file, before concluding someone reverted your work, before any branch operation, and before committing, pushing, or merging — this is almost always relevant here.

Its SKILL.md is about 1.3k 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 Development, covering Git worktrees. It works with Git. The repository describes itself as: A framework for building agentic apps.

When your agent uses it

  • Tasks that involve Git worktrees

Example prompts

  • “/concurrent-agents”

What it can do on your machine

Read from SKILL.md and the folder at commit e16da0c. 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

    Shell commands in SKILL.md call:

    • git
    • gh

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git and gh, which can reach the network depending on how they are called.

    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

Concurrent Agents loads about 1.3k tokens when it runs. Until then it costs about 74 tokens; SKILL.md has 694 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~74
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k

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 694 words (~1,301 tokens).

“Steve runs many Claude Code and Codex sessions against this one checkout on purpose, often on the same branch or file. Default assumption on every task: the working tree is shared branch state. Read existing changes before editing them, and…”
