- Works in 2 steps: Reply with exactly one short paragraph:… → Do not read or modify any files.

What it does
Kit Hello is an agent skill from chrisblattman/claudeblattman. Smoke-test skill for the starter kit. Confirms the plugin installed and skills load. Use when the user runs /kit-hello or asks to verify the starter kit installation.
Its SKILL.md is about 170 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 Testing & QA, covering Project scaffolding and QA and bug reports. The repository describes itself as: Claude Code for academics — skills, agents, and setup guides. The licence is MIT.
When your agent uses it
- The user runs /kit-hello
- Asks to verify the starter kit installation
Example prompts
- “/kit-hello”
Workflow steps
2 steps, taken from the first numbered list in SKILL.md.
- Reply with exactly one short paragraph: confirm the starter-kit plugin is installed, state the plugin version (0.1.1), and tell the user…
- Do not read or modify any files.
What it can do on your machine
Read from SKILL.md and the folder at commit 12e14d4. 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.
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
Kit Hello loads about 166 tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 74 words of instructions outside code blocks.
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.
