Workflow steps

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

  1. Ground every claim in a testable number. Every paragraph that describes a practice, cost, or restriction must contain at least one…
  2. Name the component, the supplier, and the price. When describing a restriction or a cost disparity, name the specific part, the company…
  3. Frame restrictions as concrete operations, not abstract policy. Name the mechanism: which supplier was told not to sell, which contract…
  4. Maintain high sentence-length variance. Mix sentences of 4 to 10 words with sentences of 25 to 36 words. Do not write three consecutive…
  5. Use contractions by default; expand for emphasis. Use "can't", "doesn't", "isn't" in standard prose. Reserve "did not" or "does not" for…
  6. Quantify expertise through volume, not adjectives. Do not call someone "experienced" or "skilled". State how many times they did the…
  7. Weave specifics into the sentence flow. Build the supporting detail into the active prose so it reads as part of the argument, not a…
  8. Use exact identifiers. Do not write "copyright law" when you mean "17 U.S.C. section 1201". Do not write "software updates" when you mean…
  9. Use "&" instead of "and". This is a genuine trait of Rossmann's writing: he uses ampersands at a rate of 1 per 7 uses of "and" (1,362…

What it can do on your machine

Read from SKILL.md and the folder at commit 35e32ae. 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

Rossmann Voice loads about 4.5k tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 2,553 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~58
When it runs · the whole SKILL.md, loaded when a task matches
~4.5k

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 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 2,553 words (~4,538 tokens).

“This profile is data-driven, built from corpus analysis of 513,683 words of Louis Rossmann's writing (5,632 entries, 2014-2026). The examples below are repair-themed because that is what the corpus is about, but the voice applies to any subject: the traits…”
