What it does
GitHub GitLab Mirror is an agent skill from AgentsMesh/AgentsMesh. Audits or synchronizes the authoritative GitHub main branch to the internal GitLab mirror without importing GitLab-only history back into GitHub. Use when checking GitHub/GitLab consistency, updating the internal mirror, or resolving a divergence between the two remotes.
Its SKILL.md is about 710 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It works with GitLab and GitHub. The repository describes itself as: The AI Agent Workforce Platform. Run a hundred AI coding agents across your own machines — schedule, isolate, and steer them all from one console.
When your agent uses it
- Checking GitHub/GitLab consistency
- Updating the internal mirror
- Resolving a divergence between the two remotes
Example prompts
- “Use the github-gitlab-mirror skill to audit or synchronizes the authoritative GitHub main branch to the internal GitLab mirror without importing…”
- “/github-gitlab-mirror”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Fetch both authoritative refs
- Record both SHAs and show commits unique to either side
- Classify the relationship
What it can do on your machine
Read from SKILL.md and the folder at commit d38e393. 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.
Context cost
GitHub GitLab Mirror loads about 707 tokens when it runs. Until then it costs about 73 tokens; SKILL.md has 261 words of instructions outside code blocks.
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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 261 words (~707 tokens).
“GitHub main is the single source of truth. GitLab exists to build and deploy the same commit internally.”
