What it does

Slack is an agent skill from Kevin100202/Rocket-Design-and-Manufacturing-Automation-Program-from-Shenzhen22highschool. Slack tool actions: send/read/edit/delete messages, react, pin/unpin, list pins/reactions/emoji, member info.

Its SKILL.md is about 420 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with Slack and React. The repository describes itself as: Rocket Design and Manufacturing Automation Program By Students.

Example prompts

  • “/slack”

What it can do on your machine

Read from SKILL.md and the folder at commit f924634. 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 json).

    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

Slack loads about 419 tokens when it runs. Until then it costs about 29 tokens; SKILL.md has 61 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~29
When it runs · the whole SKILL.md, loaded when a task matches
~419

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

Without a licence we can't republish the file, so here is its outline and opening line. It has 61 words (~419 tokens).

“Use the slack tool. Reuse channelId and Slack timestamp message IDs from context when present.”
