When your agent uses it
- Tasks that involve Plain language and style rules
Example prompts
- “/plain-language-letters”
What it can do on your machine
Read from SKILL.md and the folder at commit 4a6c651. 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
Plain Language Letters loads about 206 tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 61 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.

[DEPRECATED] Plain-Language Letters → see /client-letter and /status client
This skill was split during the v2 rebuild:
Routine correspondence (appointment confirms, document requests, brief "we filed it" updates) →
skills/client-letter/— use/client-letter [type]Substantive client status updates →
skills/status/in client-facing mode — use/status client
Both apply the plain-language standards (reading level, no jargon) from CLAUDE.md.
