At a glance

Branch one workstream into a new workstream with a frozen starting snapshot.

  • Runs Shell scripts from its folder

What it does

Branch is an agent skill from dchu917/ctx. Branch one workstream into a new workstream with a frozen starting snapshot.

Its SKILL.md is about 100 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including scripts (for example `scripts/branch.sh` and `scripts/skills/branch.sh`).

The repository describes itself as: Local context manager for Claude Code and Codex with workstreams, transcript binding, and branching. The licence is MIT.

Example prompts

  • “/branch”

Requirements

  • A Bash shell

What it can do on your machine

Read from SKILL.md and the folder at commit bdb602c. 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

    Ships 2 files in scripts/ (Shell), which the agent can run.

    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

Branch loads about 104 tokens when it runs. Until then it costs about 21 tokens; SKILL.md has 37 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~21
When it runs · the whole SKILL.md, loaded when a task matches
~104

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); the scripts in this folder are not scanned.

Usage

  • /branch <source-workstream> <target-workstream>

Backing script

  • scripts/branch.sh

Notes

  • The target workstream must not already exist.
  • The branch gets a snapshot of the source workstream's current context, but it does not inherit the source's external Claude/Codex transcript bindings.
