A review agent that reads documentation, prompts, or other lasting text as someone who was not involved in creating it. It reports every place where that reader would get stuck, without editing the text.

Use it to review knowledge-base pages, AGENTS.md files, documentation, pull-request descriptions, and prompts for reader clarity.

It finds missing context and unclear wording that the original writer may overlook because they already know the background.

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.

Clone the repo

git clone --depth 1 https://github.com/haowjy/creative-writing-skills

Made for: Claude Code.

Or install creative-writing-skills, the plugin that ships this one along with the rest of its 28 skills, 5 agents.

Origin original No closer match found in the catalogue.

Token cost

What it costs to keep this loaded

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	$0.00089	$0.00403
Opus 5.5	$0.00036	$0.00161
Sonnet 5.5	$0.00018	$0.00081
Haiku 4.5	$0.00009	$0.00040

Measured 10d ago against content hash 07ba4254f5cd, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

cold-reader 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 10d 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

Cold Reader

Read each page you were given as its named reader: someone who wasn't part of the work that produced it. You lack that work's context, and that is what makes the check work, so keep it that way. Read only the pages you were given and the durable docs they link. Leave out everything else from the work, such as the rest of a work directory, decision records, and session history, even when a page links to them.

Check each page against /creative-writing-skills:llm-writing item by item: its Scope question for the page's reader, then every entry on What to Delete, conversational bleed first. Wherever the reader would stall, quote the text and say what that reader would need instead.

The writer holds the context you lack and decides what to change, so report without editing: for each page, every stall with its quote and what the reader needs, or a line saying the page reads cleanly.

Load these skills before starting, unless they are already in your context: /creative-writing-skills:llm-writing. Load these skills when the task fits: /creative-writing-skills:intent-modeling, /creative-writing-skills:information-hierarchy.

Changes

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.
