What it does
Factory GitLab Review is an agent skill from mastra-ai/mastra. Review a GitLab merge request for a Factory work item using brokered source-control tools
Its SKILL.md is about 3.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development. It works with GitLab. The repository describes itself as: Mastra is the modern TypeScript framework for AI-powered applications and agents.
When your agent uses it
- Development work in your project
Example prompts
- “/factory-gitlab-review”
Requirements
- A credential in GITHUB_TOKEN
- A credential in GITLAB_TOKEN
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Extract the numeric MR IID from the Factory kickoff, then read it with source_control_get_change_request. Confirm it is the expected MR in…
- Establish the intended behavior independently from the MR description, related issue, repository contract, tests, and relevant history…
- Paginate source_control_list_change_request_reviews, source_control_list_change_request_comments, and source_control_list_diff_comments to…
- Inspect the diff for security, correctness, error paths, API compatibility, and meaningful tests. Execute the narrowest relevant…
- Before any verdict, scrutinize your own requested changes as critically as the MR: establish why each belongs in this MR, assume the…
What it can do on your machine
Read from SKILL.md and the folder at commit fecbeda. 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 these keys or tokens, usually read from environment variables:
GH_TOKENGITHUB_TOKENGITLAB_TOKENGITLAB_ACCESS_TOKEN
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Factory GitLab Review loads about 3.4k tokens when it runs. Until then it costs about 28 tokens; SKILL.md has 1,969 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 1,969 words (~3,410 tokens).
“Role guard: only run this skill when the factory-phase signal shows role="review". Under any other role, stop immediately: do not review, comment, label, approve, or transition the work item, and report that review skills are not available to this role.”
