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 | $0.00048 | $0.02827 |
| Opus 5 | $0.00024 | $0.01413 |
| Sonnet 5 | $0.00010 | $0.00565 |
| Haiku 4.5 | $0.00005 | $0.00283 |
Grade B, and why
content-voice-setup scanned grade B with 1 finding 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.
Strips warnings and disclaimersmediumAnti-refusal
Omitting safety caveats hides risk from the user and is a common jailbreak preamble.
- Do not lecture — stay conversational. If a segment reads as a monologue, cut it or reframe as a question. How it starts
The opening of the file, as written. The whole thing — 255 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Content Voice Setup
This skill configures Claude to write in your brand voice across the platforms you select. It generates a small CLAUDE.md pointer plus one .claude/rules/content-voice-<platform>.md file per selected platform. It does NOT configure publishing tools, analytics, media pipelines, or scheduling — that is out of scope and intentionally so.
Handoff context: Read skills/_shared/consume-handoff.md and run it with the handoff block (if any). The helper guarantees the following locals: detected_language, existing_claude_md, inferred_use_case, repo_signals, graphify_candidate. Use detected_language for all user-facing prose; generated file content stays in English.
Existing CLAUDE.md: If existing_claude_md: true, DO NOT overwrite it. Append a new delimited section at the end of the file:
<!-- onboarding-agent:start setup=content-voice skill=content-voice-setup section=claude-md -->
## Claude Onboarding Agent — Content Voice Setup
...generated content...
<!-- onboarding-agent:end -->
If the delimited block already exists from a previous run, replace only the content between the markers; leave the rest untouched. Wrap generated .gitignore entries in # onboarding-agent: content-voice — start / — end markers so /upgrade-setup can refresh them non-destructively.

Step 1: Install Dependencies
Read skills/_shared/offer-superpowers.md and run it with skill_slug: content-voice-setup, mandatory: false, capability_line: "A widely used free Claude Code skills library. The brainstorming skill is useful for exploring angles before committing to a voice for a given piece." The helper asks the user, delegates to skills/_shared/installation-protocol.md on yes, and sets superpowers_installed, superpowers_scope, superpowers_method.
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.

content-voice-setup is a skill published in the GitHub repository a2ngerer/claude_onboarding_agent (5 stars, last pushed yesterday), licensed MIT. It adds 48 tokens to every session and 2,827 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 1 finding (strips warnings and disclaimers).
