Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00043 | $0.00204 |
| Opus 5 | $0.00022 | $0.00102 |
| Sonnet 5 | $0.00009 | $0.00041 |
| Haiku 4.5 | $0.00004 | $0.00020 |
Grade A, and why
technical-writing 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 9d 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.

What it actually says
Technical Writing
Audience
Assume readers are at least as smart as you, so do not over-explain. State information once and move on.
Style
Write concise, complete sentences using active voice and present tense. Each paragraph or bullet should express a single idea.
Formatting
- Do not use emojis.
- Do not use bold or italics.
- Use headings, lists, and code blocks only when they add clarity.
- Use fenced code blocks with language identifiers.
Paths
Always use relative file paths: docs/testing.md, not /Users/name/project/docs/testing.md.
Do Not Repeat
Link to existing resources instead of duplicating content. Reference other docs, web pages, or files rather than restating their information.
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.

technical-writing is a skill published in the GitHub repository saffron-health/libretto (889 stars, last pushed 19d ago), licensed MIT.
