What is create-branch?

A command that creates a Git branch and a linked worktree using a project naming pattern. A Git worktree is a separate directory connected to the same repository, allowing another branch to be worked on independently.

Use it to start feature, fix, documentation, refactoring, test, or maintenance work with a named branch, sibling worktree, and shared environment file.

It standardizes branch names and sets up a separate working directory without requiring each setup step by hand.

How kayba-ai/agentic-context-engine configures Claude Code

About the project

Agentic Context Engine is an open-source engine that gives AI agents a persistent learning loop, helping them remember successful strategies and learn from failures across sessions. It is used to improve production agents, and also powers Kayba’s hosted service. Catalogue add-ons support workflows for operating and configuring the engine.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.00490
Opus 5.5	$0.00000	$0.00196
Sonnet 5.5	$0.00000	$0.00098
Haiku 4.5	$0.00000	$0.00049

Security

Grade A, and why

create-branch 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 2mo 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

Create a new git branch with an associated worktree following the project naming convention.

Format: <type>/<developer>/<description> Worktree: ../<sanitized-branch-name> (sibling to current worktree)

Arguments: $ARGUMENTS should be in format: <type> <description>

Examples:

/create-branch feature add-caching → branch: feature/<dev>/add-caching, worktree: ../feature-<dev>-add-caching
/create-branch fix login-error → branch: fix/<dev>/login-error, worktree: ../fix-<dev>-login-error

Steps:

Parse type and description from arguments (validate type is one of: feature, fix, docs, refactor, test, chore)
Get developer name from git config user.name (sanitize: lowercase, replace spaces with hyphens)
Construct branch name: <type>/<developer>/<description>
Construct worktree path: ../<type>-<developer>-<description> (replace all / with -)
Create branch and worktree atomically: git worktree add -b <branch> <worktree-path>
Symlink .env from the main worktree into the new worktree:
- Get the main worktree path: git worktree list --porcelain | head -1 (first worktree line)
- If <main-worktree>/.env exists, create symlink: ln -s <main-worktree>/.env <new-worktree>/.env
- If .env doesn't exist in main worktree, skip silently
Report success with the created branch name and worktree path

Valid types: feature, fix, docs, refactor, test, chore

On success, output:

✓ Created branch: <branch-name>
✓ Created worktree: <worktree-path>
✓ Linked .env → <main-worktree>/.env

To switch to the new worktree:
  cd <worktree-path>

Error handling:

If type is invalid, show valid types and abort
If branch already exists, suggest checking it out instead
If worktree path exists, suggest using existing worktree

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.
