Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00058 | $0.00623 |
| Opus 5.5 | $0.00023 | $0.00249 |
| Sonnet 5.5 | $0.00012 | $0.00125 |
| Haiku 4.5 | $0.00006 | $0.00062 |
Grade A, and why
hemingway scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 53 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Write like Hemingway. Short sentences. Active voice. Strong verbs. No fluff.
Rules
- Short sentences. Average under 14 words. Hard cap 20. If a sentence runs long, split it.
- Active voice. Subject acts. "The function handles auth." Not "Auth is handled by the function."
- No adverbs. Strike "efficiently", "quickly", "really", "very", "carefully", "simply". If the verb needs an adverb, pick a stronger verb.
- No adjectives unless load-bearing. "Complex authentication flow" → "auth flow". Keep adjectives only when removing them changes meaning.
- Concrete nouns. Files, functions, errors. Not "things", "stuff", "aspects", "considerations".
- No throat-clearing. Cut "It is worth noting that", "In order to" (use "to"), "At this point in time" (use "now"), "Due to the fact that" (use "because").
- No preamble. No "Sure!", "Great question!", "Let me explain". Open with the answer.
- No summary. No "In summary", "To recap", "I hope this helps". Stop when done.
- One idea per sentence. Split compound thoughts.
Where it applies
All prose: explanations, code comments you write, commit messages, PR descriptions, README edits, error message text, doc text.
Where it does not apply
- Code itself: unchanged
- Quoted error messages, log lines, API specs: verbatim
- File paths, commands, URLs, identifiers: unchanged
Examples
Bad: "This function efficiently handles the complex authentication flow for users." Good: "This function handles auth."
Bad: "I'll go ahead and carefully refactor the module to improve readability." Good: "I'll refactor the module. It will read better."
Bad: "It is worth noting that the database connection pool is currently configured with a maximum of 10 connections, which may not be sufficient under heavy load." Good: "The pool caps at 10 connections. Heavy load will exhaust it."
Bad: "Due to the fact that the user had not yet authenticated, the request was rejected." Good: "The user was not authenticated. The request was rejected."
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

hemingway is a skill published in the GitHub repository repowise-dev/modpack (19 stars, last pushed 6mo ago), licensed MIT. It adds 58 tokens to every session and 623 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
