racecraft-plugins-public: Skill for Claude Code

.claude/skills/speckit-git-feature/SKILL.md

speckit-git-feature is a skill for Claude Code from racecraft-lab/racecraft-plugins-public. It costs 16 tokens per session (808 once invoked), scanned A, a copy of speckit-git-feature, MIT.

A helper for creating and switching to a Git feature branch with a sequential number or timestamp in its name. The branch is a separate line of code work.

In plain words
What is it for?
Use it when starting work on a specification to create the corresponding feature branch; it does not create the specification files.
Why use it?
It applies the project's naming strategy automatically and can accept an explicitly supplied branch name.

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 9d 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.

Origin

This is a copy

88% identical to speckit-git-feature — 9 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.

Git Feature Skill

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.
