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.

SkillSpector: 2 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00196 | $0.00678 |
| Opus 5 | $0.00098 | $0.00339 |
| Sonnet 5 | $0.00039 | $0.00136 |
| Haiku 4.5 | $0.00020 | $0.00068 |
Grade A, and why
writing-quality-editor 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 yesterday.
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 — 48 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Writing Quality Editor
Create or improve writing for its intended reader and purpose while preserving what the material is allowed to mean. Follow the user's request and the host workflow's ownership of files, approvals, document classification, and publication.
Choose The Task
Do not require a mode name. Choose by the requested outcome and which material is authoritative.
| Requested outcome | Mode |
|---|---|
| A new text from facts, notes, a brief, or research | Compose |
| Findings or diagnosis without replacement text | Assess |
| Improvements to authoritative source prose in the same language | Revise |
| A source text rewritten for readers of another language | Adapt |
When both facts and prose are supplied, choose Compose only if they are material for a new document.
If the prose itself remains the meaning authority, use Revise or Adapt. A bare "review this" or "봐 줘"
does not authorize replacement prose; use Assess. Ask a focused question when explicit instructions conflict
about mutation or language scope. Do not silently choose the broader action.
Load The Applicable Contract
All paths below are relative to the installed skill package root. Read the selected contract completely.
| Request | Contract |
|---|---|
Compose with Korean output |
references/korean-compose.md |
Assess, every Revise or Adapt, or non-Korean Compose |
references/established-contract.md and the applicable references it requires |
Compose requiring public-source research |
Also read references/research-backed-compose.md |
The Korean Compose contract is self-contained for a supplied brief. Do not load the established editing contract
or its full review rubric for that path. A request to polish existing Korean prose remains Revise and uses the
established contract; Korean output alone does not select the new-drafting path.
If a required contract cannot be read, identify the missing file before writing or editing instead of inventing its rules. The established contract's resource paths also refer to the package root, not its own directory.
What ships with it
10 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

writing-quality-editor is a skill published in the GitHub repository kyungseo/skillstead (78 stars, last pushed 2d ago), licensed Apache-2.0. It adds 196 tokens to every session and 678 once invoked, about $0.0010 per session on Opus 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.
