When your agent uses it
- Tasks that involve Messaging and chat bots
Example prompts
- “/imessage”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Always confirm recipient and message content before sending
- Never send to unknown numbers without explicit user approval
- Verify file paths exist before attaching
- Don't spam — rate-limit yourself
What it can do on your machine
Read from SKILL.md and the folder at commit be46b39. 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:
jqbrew
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
Imessage loads about 606 tokens when it runs. Until then it costs about 17 tokens; SKILL.md has 167 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.
SKILL.md
The full file from RedWoodOG/Hermes-Desktop at commit be46b39, republished under its MIT licence (© RedWoodOG). 167 words, ~606 tokens.
