What it does

Speckit Git Validate is an agent skill from kunstmusik/blue. Validate current branch follows feature branch naming conventions

Its SKILL.md is about 490 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: Requires spec-kit project structure with .specify/ directory

It sits in Development, covering Spec-driven development and Git workflow. It works with Git. The repository describes itself as: Blue - An Integrated Music Environment. The licence is GPL-3.0.

When your agent uses it

  • Tasks that involve Spec-driven development
  • Tasks that involve Git workflow

Example prompts

  • “/speckit-git-validate”

Requirements

  • Compatibility (from SKILL.md): Requires spec-kit project structure with .specify/ directory

Workflow steps

2 steps, taken from the first numbered list in SKILL.md.

  1. Sequential: ^[0-9]{3,}- (e.g., 001-feature-name, 042-fix-bug, 1000-big-feature)
  2. Timestamp: ^[0-9]{8}-[0-9]{6}- (e.g., 20260319-143022-feature-name)

What it can do on your machine

Read from SKILL.md and the folder at commit ab9862c. 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

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

  • Network

    No URLs in SKILL.md. Its commands use git, 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.

  • Compatibility

    Requires spec-kit project structure with .specify/ directory

    From compatibility in the SKILL.md frontmatter.

Context cost

Speckit Git Validate loads about 489 tokens when it runs. Until then it costs about 22 tokens; SKILL.md has 201 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~22
When it runs · the whole SKILL.md, loaded when a task matches
~489

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.

Git Validate Skill

Validate Feature Branch

Validate that the current Git branch follows the expected feature branch naming conventions.

Prerequisites

  • Check if Git is available by running git rev-parse --is-inside-work-tree 2>/dev/null
  • If Git is not available, output a warning and skip validation:
    [specify] Warning: Git repository not detected; skipped branch validation

Validation Rules

Get the current branch name:

bash
git rev-parse --abbrev-ref HEAD

The branch name must match one of these patterns:

  1. Sequential: ^[0-9]{3,}- (e.g., 001-feature-name, 042-fix-bug, 1000-big-feature)
  2. Timestamp: ^[0-9]{8}-[0-9]{6}- (e.g., 20260319-143022-feature-name)

Execution

If on a feature branch (matches either pattern):

  • Output: ✓ On feature branch: <branch-name>
  • Check if the corresponding spec directory exists under specs/:
    • For sequential branches, look for specs/<prefix>-* where prefix matches the numeric portion
    • For timestamp branches, look for specs/<prefix>-* where prefix matches the YYYYMMDD-HHMMSS portion
  • If spec directory exists: ✓ Spec directory found: <path>
  • If spec directory missing: ⚠ No spec directory found for prefix <prefix>

If NOT on a feature branch:

  • Output: ✗ Not on a feature branch. Current branch: <branch-name>
  • Output: Feature branches should be named like: 001-feature-name or 20260319-143022-feature-name

Graceful Degradation

If Git is not installed or the directory is not a Git repository:

  • Check the SPECIFY_FEATURE environment variable as a fallback
  • If set, validate that value against the naming patterns
  • If not set, skip validation with a warning
