What is github-manage?

A GitHub operations helper for working with repositories through the GitHub command-line tool, including creating milestones with descriptions and due dates.

It helps create GitHub milestones, check authentication, find repository information, and return the resulting milestone link and number.

It removes the need to remember GitHub CLI commands and manually look up repository details before performing routine project tasks.

github-manage — Skill for Claude Code by matteocervelli

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add matteocervelli/llms --skill github-manage

Clone the repo

git clone --depth 1 https://github.com/matteocervelli/llms

Made for: Claude Code.

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	$0.00013	$0.00644
Opus 5	$0.00006	$0.00322
Sonnet 5	$0.00003	$0.00129
Haiku 4.5	$0.00001	$0.00064

Security

Grade A, and why

github-manage 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 6d 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.

Usage

/gh-milestone-create                    # Interactive mode
/gh-milestone-create "Sprint 3"         # With title
/gh-milestone-create "Sprint 3" 2025-11-15  # With title and due date

What it does

Checks if GitHub CLI is authenticated
Gets repository information
Creates milestone with specified details
Optionally sets due date
Returns milestone URL and number

Execution

!echo "📋 Creating GitHub milestone..." !gh auth status !gh repo view --json nameWithOwner,url | grep -E 'nameWithOwner|url' !gh milestone create "New Milestone" --description "Milestone description" --due-date 2025-12-31

Interactive Example

For interactive milestone creation with prompts:

!gh api repos/:owner/:repo/milestones -f title="Sprint 3" -f description="Sprint 3 objectives" -f due_on="2025-11-15T23:59:59Z" -f state="open"

Parameters

title (required): Milestone title
description (optional): Detailed description of milestone goals
due-date (optional): Due date in YYYY-MM-DD format
state (optional): open or closed (default: open)

Examples

Basic milestone

/gh-milestone-create "v1.0 Release"

Milestone with due date

/gh-milestone-create "Q4 Goals" 2025-12-31

Using GitHub API directly

gh api repos/owner/repo/milestones \
  -f title="Sprint 4" \
  -f description="Complete core features" \
  -f due_on="2025-11-30T23:59:59Z"

Listing Existing Milestones

gh milestone list
gh api repos/:owner/:repo/milestones

Requirements

GitHub CLI (gh) installed and authenticated
Write access to the repository
Valid repository context

Tips

Use clear, action-oriented milestone titles
Set realistic due dates
Include objectives in description
Link issues to milestones for tracking
Use milestones for sprint planning
Close milestones when complete

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.
