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 | $0.00042 | $0.00763 |
| Opus 5 | $0.00021 | $0.00381 |
| Sonnet 5 | $0.00008 | $0.00153 |
| Haiku 4.5 | $0.00004 | $0.00076 |
Grade A, and why
a1-copy-editing 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 12d 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 — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Copy Editing
Improve or review a user-selected existing draft while preserving its source-supported meaning.
The user should be able to paste text, state an editing or review intent in ordinary language, and receive a source-faithful result without a setup interview.
Entry Contract
Accept a request when all conditions are true:
- A user-selected existing draft: text the user pasted or attached in the conversation, or a document they explicitly selected as the editing target.
- An editing, feedback, or review intent directed at that draft.
- Every requested deliverable edits or reviews that draft.
When the user explicitly invokes this skill without selecting a draft, ask them to paste, attach, or name the draft and stop.
For a mixed request, state that A1 Copy Editing edits or reviews selected existing drafts and stop without producing any deliverable.
Marketing context is optional. Read only the first existing repository context in this order: .agents/marketing-context.md, then .claude/marketing-context.md when the canonical path is absent, then root marketing-context.md when both earlier paths are absent. Do not read or merge a lower-priority context. If none exists, continue from the user's text and instruction.
Do not block on missing audience, channel, goal, tone, constraints, or marketing context. Ask only when every safe edit or useful review would choose between materially different meanings. If any safe useful result is possible, produce it and briefly state a material limitation instead of asking.
Runtime
Every accepted request must follow the copy-editing spine in order. The spine owns stage order and routes each stage to its canonical behavior contract.
Output
For an editing operation, unless the user requests edited text only, return:
- Edited version: the rewritten text or two to three clearly different options.
- Change summary: one to five concise explanations tied to changes actually made.
- Assumptions: only when material or explicitly requested.
What ships with it
44 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.
- 12d ago First seen · 60 lines · 42 tokens per session scan A 01ea3d03c633
a1-copy-editing is a skill published in the GitHub repository ztemerbekov/a1-marketing-skills (8 stars, last pushed 13d ago), licensed MIT. It adds 42 tokens to every session and 763 once invoked, about $0.0002 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 2026-08-31.
