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 | $0.00031 | $0.00759 |
| Opus 5 | $0.00015 | $0.00380 |
| Sonnet 5 | $0.00006 | $0.00152 |
| Haiku 4.5 | $0.00003 | $0.00076 |
Grade A, and why
file-manager 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 3d 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.

File Manager Skill
This skill provides file management operations on the local system. It can open files, reveal them in the file explorer, and search for files.
⚠️ Security Note
Operations on files outside the workspace require user approval. The agent will pause and ask for confirmation before:
- Opening files outside the current project
- Revealing files in external locations
- Executing any file operations on system directories
When to Use
- User asks to "open" a document, image, or file
- User wants to "show in explorer" or "reveal in finder"
- User needs to find a file on their system
- User asks about file details (size, dates, type)
Available Commands
Open File
Opens a file with its default application.
python scripts/file_ops.py open "/path/to/document.pdf"
Examples:
- Open a PDF:
open ~/Documents/report.pdf - Open an image:
open ./screenshot.png - Open a URL:
open https://example.com
Reveal in Explorer/Finder
Shows the file in the system file manager, with the file selected.
python scripts/file_ops.py reveal "/path/to/file.txt"
Search for Files
Search for files by name or pattern.
python scripts/file_ops.py search "*.pdf" --location ~/Documents
python scripts/file_ops.py search "report" --location ~/Documents --recursive
Get File Info
Get detailed information about a file.
python scripts/file_ops.py info "/path/to/file.txt"
Returns: size, creation date, modification date, file type, permissions.

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.
