Mastra Agent Skills
mastra-ai/skillsMastra's official skills: a framework guide that routes to current docs and ten references, and a Factory supervisor skill for the mastra api CLI.
Covers agents-cli scaffold create, enhance and upgrade: choosing a template, deployment target, CI/CD runner and session storage for a new agent project.
Clear flag mapping and guardrails for scaffolding; narrow but accurate for agents-cli users.
The scaffold skill tells the agent how to create or extend an agent project with agents-cli. It makes clarifying requirements mandatory for new projects, pointing to the workflow skill's design dialogue first. It then maps user choices to flags: the agent template (ADK Python by default, or ADK Go), prototype mode with no deployment, the deployment target (Agent Runtime, Cloud Run or GKE), a CI/CD runner (GitHub Actions or Google Cloud Build) and session storage (in memory, Cloud SQL or platform sessions).
It includes naming constraints (project names up to 26 characters, lowercase), warns not to create the directory before running create, and says to pass the right guidance filename for the IDE (GEMINI.md, CLAUDE.md or AGENTS.md). For existing code it describes scaffold enhance with an agent-directory flag, and scaffold upgrade for newer CLI versions. It lists removed flags and templates so an agent does not reach for them, and sends retrieval, memory and similar capabilities to recipes in the ADK code skill. The SKILL.md is about 13 KB with one flags reference file.
A 13 KB SKILL.md with a flags reference file; no scripts or evals.
Markdown-only guide to creating, enhancing and upgrading agent projects with agents-cli scaffold. Scaffold commands write project files and can overwrite scaffolding files with --force; the skill says to confirm requirements, CI/CD runner and any Git repo creation with the user. The agents-cli tool was not reviewed and sends usage telemetry unless you opt out.
uv tool install google-agents-cli; scaffolding also generates a project with its own dependencies.SKILL.md:24The skill folder (2 files) on Oct 29, 2026. Not a full review: it relies on code outside the repository: agents-cli (PyPI package google-agents-cli, installed with uv tool install).
NVIDIA SkillSpector static scan: 15 pattern hits (Excessive Agency 12, Tool Misuse 2, analysis-evasion 1). Hits are CLI flag names in documentation (--skip-checks, --auto-approve, --force) and phrases like 'without asking' that are in fact rules (the skill says never to create a Git repo or push without asking). Nothing executes from the skill folder.
A review, not a certification. Skills change after we check them — read the files before installing.
Apache-2.0 — commercial use allowed.
Not really. Scaffolding is a quick interactive step after requirements are clarified.

It ships in the google/agents-cli repository. Run uvx google-agents-cli setup or npx skills add google/agents-cli; the skill expects the agents-cli binary (uv tool install google-agents-cli).
It adds deployment, CI/CD or other infrastructure files to an existing project, and the skill says to pass an agent-directory flag if your agent code is not in app/. scaffold upgrade moves a project to a newer agents-cli version.
