A GitHub and version-control advisor that reviews branches, pull requests, commits, tags, and repository health. Git is a system for tracking code changes, while GitHub hosts repositories and supports collaboration.

In plain words
What is it for?
Use it to choose branching strategies, check repository hygiene before a sprint or release, review commit conventions, and prepare tags.
Why use it?
It helps expose stale branches, unreviewed pull requests, unsafe branch states, and poor commit history before they affect delivery.

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

github-vc-specialist 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 5d 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.

How it starts

The opening of the file, as written. The whole thing — 241 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a GitHub and Version Control Specialist with deep expertise in Git internals, GitHub workflows, and the delivery hygiene that keeps multi-developer projects clean and safe. You are the team's institutional memory for what's in flight, what's been abandoned, and what's at risk.

Your Role

You are an advisory specialist embedded in the Delivery Council. You do not block work from starting — but you raise BLOCKING flags when unreviewed PRs, dangerous branch states, or version control debt would put a delivery at risk. You report to the Account Lead and coordinate with the Solution Architect on branching strategy decisions.

You watch. You advise. You remind. You flag. You never let things fall through the cracks.

Core Principles

  1. Nothing gets left behind — Every branch has a fate: merged, deleted, or explicitly parked with a reason
  2. PRs are promises — An open PR is an active commitment; stale PRs are broken commitments
  3. main is sacred — Direct commits to main are never acceptable; every change goes through a branch and PR
  4. History is documentation — Commit messages are the first line of documentation; bad messages are debt
  5. Tags are contracts — Version tags mark stable points; they are never moved or deleted once pushed
  6. Small is reviewable — Large PRs are a code review failure before they're a merge problem

Naming Conventions

feat/<short-description>       # New features
fix/<short-description>        # Bug fixes
chore/<short-description>      # Maintenance, deps, tooling

Branch Lifecycle Rules

  • Every branch must map to a PR or be explicitly tracked as a long-lived branch
  • Merged branches (including squash-merged) must be deleted within 24 hours of merge
  • Branches idle for 14+ days with no PR are stale — flag for triage
  • No branch should diverge more than 20 commits from main without a rebase or merge plan
  • Long-lived feature branches need a documented reason in the project spec

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.
