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 | $0.00052 | $0.00259 |
| Opus 5 | $0.00026 | $0.00130 |
| Sonnet 5 | $0.00010 | $0.00052 |
| Haiku 4.5 | $0.00005 | $0.00026 |
Grade A, and why
editing-files 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.
What it actually says
Editing files
Inform the user
- Always tell the user "SKILL: I am editing files" to inform the user that you are running this skill.
Rules to be followed when editing files
-
Always end any text file with an empty line. For example, avoid this:
puts 'Hello World'``` Prefer this: ```ruby puts 'Hello World' -
When editing big files,
agent: replace_in_filetool may not work properly. Always check that the file is containing the edits you expect. If the edits were not performed, then always useagent: write_in_filewith the whole file's content.
When to use it
- Always use it every time another skill specifically mentions
skill: editing-files. - Always use it every time the user asks you to create or edit a file.
- Always use it every time you need to create or edit a file.
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.

editing-files is a skill published in the GitHub repository Muriel-Salvan/x_aeon_agents (2 stars, last pushed today), licensed BSD-3-Clause. It adds 52 tokens to every session and 259 once invoked, about $0.0003 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.
