speckit-git-feature

speckit-git-feature is a skill for Claude Code, Codex from Badminton-Apps/badman. It costs 16 tokens per session (794 once invoked), scanned A, a copy of speckit-git-feature, Apache-2.0.

A Git workflow skill for creating and switching to a feature branch, which is a separate line of work for a code change. It supports numbered, timestamped, or explicitly named branches.

In plain words
What is it for?
Use it when starting development for a feature from a written specification.
Why use it?
It standardizes branch creation and checks whether the current directory is a Git project before attempting the change.

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.

Security

Grade A, and why

speckit-git-feature 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 today.

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.

Origin

This is a copy

100% identical to speckit-git-feature — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Create Feature Branch

Create and switch to a new git feature branch for the given specification. This command handles branch creation only — the spec directory and files are created by the core /speckit.specify workflow.

User Input

$ARGUMENTS

You MUST consider the user input before proceeding (if not empty).

Environment Variable Override

If the user explicitly provided GIT_BRANCH_NAME (e.g., via environment variable, argument, or in their request), pass it through to the script by setting the GIT_BRANCH_NAME environment variable before invoking the script. When GIT_BRANCH_NAME is set:

  • The script uses the exact value as the branch name, bypassing all prefix/suffix generation
  • --short-name, --number, and --timestamp flags are ignored
  • FEATURE_NUM is extracted from the name if it starts with a numeric prefix, otherwise set to the full branch name

Prerequisites

  • Verify Git is available by running git rev-parse --is-inside-work-tree 2>/dev/null
  • If Git is not available, warn the user and skip branch creation

Branch Numbering Mode

Determine the branch numbering strategy by checking configuration in this order:

  1. Check .specify/extensions/git/git-config.yml for branch_numbering value
  2. Check .specify/init-options.json for branch_numbering value (backward compatibility)
  3. Default to sequential if neither exists

Execution

Generate a concise short name (2-4 words) for the branch:

  • Analyze the feature description and extract the most meaningful keywords
  • Use action-noun format when possible (e.g., "add-user-auth", "fix-payment-bug")
  • Preserve technical terms and acronyms (OAuth2, API, JWT, etc.)

Run the appropriate script based on your platform:

  • Bash: .specify/extensions/git/scripts/bash/create-new-feature.sh --json --short-name "<short-name>" "<feature description>"
  • Bash (timestamp): .specify/extensions/git/scripts/bash/create-new-feature.sh --json --timestamp --short-name "<short-name>" "<feature description>"
  • PowerShell: .specify/extensions/git/scripts/powershell/create-new-feature.ps1 -Json -ShortName "<short-name>" "<feature description>"
  • PowerShell (timestamp): .specify/extensions/git/scripts/powershell/create-new-feature.ps1 -Json -Timestamp -ShortName "<short-name>" "<feature description>"

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.
