What it does

Create Skill is an agent skill from videojs/video.js. Create repository skills. Use for repeatable agent workflows.

Its SKILL.md is about 510 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/patterns.md`, `references/principles.md` and `references/structure.md`).

The repository describes itself as: Video.js v10 - open source media player framework for HTML and React.

When your agent uses it

  • Repeatable agent workflows

Example prompts

  • “/create-skill”

Workflow steps

10 steps, taken from the first numbered list in SKILL.md.

  1. Collect concrete trigger and non-trigger examples.
  2. Check existing skills for overlap; extend or consolidate before adding another metadata entry.
  3. Choose one coherent job and a globally unique, verb-first kebab-case name.
  4. Create .agents/skills//SKILL.md with only portable frontmatter
  5. Put only essential procedure, project-specific gotchas, inputs/outputs, one compact example, and validation in SKILL.md.
  6. Add a references/ file only for conditional detail and link it directly with an explicit read condition. Add a tested script only for…
  7. Do not tell a skill to load a sibling skill. Give related skills precise, overlapping descriptions so hosts can compose them from the task.
  8. Run pnpm link:aliases to refresh compatibility directory links.
  9. Update AGENTS.md only when its compact routing index needs the skill.
  10. Run pnpm check:workspace.

What it can do on your machine

Read from SKILL.md and the folder at commit 50f59a2. 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:

    • pnpm

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use pnpm, 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

Create Skill loads about 513 tokens when it runs, and up to ~1.5k if it reads all its reference files. Until then it costs about 19 tokens; SKILL.md has 250 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~19
When it runs · the whole SKILL.md, loaded when a task matches
~513
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.5k

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 250 words (~513 tokens).

“Create a skill only when a repeatable vertical workflow needs instructions beyond what code, tests, existing docs, and general model capability already provide.”
