What it does

Creating Skills is an agent skill from NangoHQ/nango. Use when creating new agent skills or improving existing ones - ensures skills are discoverable, scannable, and effective through proper structure, discovery optimization, and real examples

Its SKILL.md is about 3.5k 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 Backend & APIs. The repository describes itself as: Connect your agents & product to 1,000 APIs.

When your agent uses it

  • Creating new agent skills
  • Improving existing ones - ensures skills are discoverable
  • Effective through proper structure
  • Discovery optimization

Example prompts

  • “/creating-skills”

Requirements

  • Python 3

Workflow steps

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

  1. Clear sequential steps: Break complex tasks into numbered operations
  2. Feedback loops: Build in verification/validation steps
  3. Error handling: What to check when things go wrong
  4. Checklists: For processes with many steps or easy-to-miss details

What it can do on your machine

Read from SKILL.md and the folder at commit b07eb10. 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

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown, yaml, typescript and bash).

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

  • Network

    No URLs in SKILL.md.

    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

Creating Skills loads about 3.5k tokens when it runs. Until then it costs about 51 tokens; SKILL.md has 1,130 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~51
When it runs · the whole SKILL.md, loaded when a task matches
~3.5k

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 1,130 words (~3,459 tokens).

“Skills are reference guides for proven techniques, patterns, or tools. Write them to help future agents quickly find and apply effective approaches.”
