When your agent uses it

Tasks that involve REST APIs

Example prompts

“/ignav”

Requirements

A credential in IGNAV_API_KEY
Pre-approved tools (allowed-tools): Bash(curl *)

Workflow steps

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

Parse the user's request (origin, destination, dates, trip type, passengers, cabin)
Look up airport codes if user gave city names
Search flights (one-way or round-trip)
Present results in markdown table
Get booking links if user wants to book

What it can do on your machine

Read from SKILL.md and the folder at commit db82131. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
- Bash(curl *)
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- curl
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
- ignav.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- IGNAV_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Ignav loads about 989 tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 320 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~45
When it runs · the whole SKILL.md, loaded when a task matches: ~989

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.

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

NoteMentions a .env fileSKILL.md:18

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.
