Skills
A skill is a reusable, named instruction package. You write the know-how once - a voice guide, a customer's rules, a recipe that works - and attach it to any agent that should carry it. The agent reads its attached skills alongside its goal, so one well-written skill upgrades every agent it is attached to, and updating the skill updates them all.
When to use a skill
Reach for a skill whenever the same know-how needs to live in more than one agent:
- Voice and tone - your brand's writing style, shared by every content agent
- Per-customer rules - "for ACME, always CC their PM and use their template", attached to each agent that touches that account
- A proven pipeline recipe - the steps and checks that made one agent reliable, packaged so new agents start from them instead of rediscovering them
If the instruction only matters to a single agent, just put it in that agent's goal. Skills earn their keep when the same text would otherwise be copy-pasted.
Working with skills
Skills are managed through the FlyMy MCPs gateway at https://mcp-agents.flymy.ai/mcp. Once your AI client is connected, you ask in plain words - the client calls the matching tool for you.
| Tool | What it does |
|---|---|
create_skill | Save a named instruction package |
list_skills | List the skills in your workspace |
get_skill | Read one skill's content |
attach_skill | Attach a skill to an agent |
detach_skill | Remove a skill from an agent |
Typical requests:
"Save these writing rules as a skill called Brand Voice."
"What skills do I have?"
"Attach the Brand Voice skill to my Newsletter agent."
"Detach the ACME Rules skill from this agent."
When an agent finally nails the tone or the process after a few corrections, say "save this as a skill" right there. The corrections become a package you attach to the next agent instead of repeating them.

Skills vs freeze
Skills and freezing both make agents repeatable, but at different layers:
| Skill | Freeze | |
|---|---|---|
| Captures | Know-how: rules, style, a recipe | One exact pipeline from a successful run |
| At run time | Agent still plans, guided by the skill | Replays the frozen instruction - deterministic, cheaper, faster |
| Scope | Attach to any number of agents | One compilation of one agent |
A skill shapes future planning - the agent stays flexible and applies the know-how to whatever input arrives. A freeze pins one exact pipeline - no re-planning at all.
They compose: attach skills while you iterate, and once a run with those skills produces exactly what you want, freeze it with freeze_agent and re-run it with run_frozen.
A frozen compilation does not change when you later edit a skill - that is the point of freezing. To pick up updated skills in a frozen workflow, run the agent live again and cut a new freeze.
