Workflow steps

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

If using (tabs) folder, DELETE src/app/index.tsx to avoid route conflicts
Check and remove lineHeight from these files

What it can do on your machine

Read from SKILL.md and the folder at commit 668a0e7. 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:
- bun
- npx
- eas
- bunx
- xcrun
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:
- apps.apple.com
- commondatastorage.googleapis.com
- eu.i.posthog.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- EXPO_PUBLIC_POSTHOG_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Zafer Skills loads about 8.5k tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 2,291 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~61
When it runs · the whole SKILL.md, loaded when a task matches: ~8.5k

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: notes

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

NoteMentions a .env fileSKILL.md:774

- Keys live in `.env` (`EXPO_PUBLIC_POSTHOG_KEY`, `EXPO_PUBLIC_POSTHOG_HOST`), never committed

NoteMentions a .env fileSKILL.md:862

5. Secrets and keys go to `.env` as `EXPO_PUBLIC_*` (and EAS environment variables for builds)

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.

Without a licence we can't republish the file, so here is its outline and opening line. It has 2,291 words (~8,532 tokens).
