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 | $0.00044 | $0.00538 |
| Opus 5 | $0.00022 | $0.00269 |
| Sonnet 5 | $0.00009 | $0.00108 |
| Haiku 4.5 | $0.00004 | $0.00054 |
Grade A, and why
file-operations 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 8d 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
Goal
Enable the agent to perform common file system operations similar to Unix/Linux commands.
Available Operations
List Directory (ls)
Use list_directory tool to list contents of a directory.
- Default: lists current directory
- Specify path to list other directories
Change Directory (cd)
Use change_directory tool to navigate to a different directory.
- Provide absolute or relative path
Print Working Directory (pwd)
Use get_current_directory tool to show the current working directory.
Make Directory (mkdir)
Use make_directory tool to create new directories.
- Creates parent directories automatically if needed
Create File
Use create_file tool to create new files.
- Optionally provide initial content
- Creates parent directories if needed
Read File
Use read_file tool to read file contents.
- Returns the full text content of the file
Write to File
Use write_to_file tool to write or append content to files.
- Set
append: trueto add to existing content - Set
append: falseto overwrite
Delete File
Use delete_file tool to remove files.
- Be careful - this is permanent!
Procedure
- When user asks to list files, use
list_directory - When user asks to navigate (cd), use
change_directory - When user asks where they are (pwd), use
get_current_directory - When user asks to create directories, use
make_directory - When user asks to create files, use
create_file - When user asks to read files, use
read_file - When user asks to write to files, use
write_to_file - When user asks to delete files, use
delete_file
Examples
User: "List files in the current directory"
→ Use list_directory with path="."
User: "Create a new file called test.txt"
→ Use create_file with path="test.txt"
User: "What's in the src folder?"
→ Use list_directory with path="src"
User: "Create a directory called output"
→ Use make_directory with path="output"
What ships with it
1 file 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.

file-operations is a skill published in the GitHub repository muhdaliyan/zeer (5 stars, last pushed 5mo ago), licensed MIT. It adds 44 tokens to every session and 538 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.
