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.

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 | $0.00015 | $0.00455 |
| Opus 5 | $0.00008 | $0.00228 |
| Sonnet 5 | $0.00003 | $0.00091 |
| Haiku 4.5 | $0.00002 | $0.00046 |
Grade A, and why
file-read-skill 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 11d 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
File Read Tool
Read raw file contents with line-based pagination. Uses the workspace-contained native filesystem backend.
Path sandbox: all paths resolve inside the per-workflow workspace root. Use workspace-relative paths (e.g. reports/data.csv); .. and ~ segments are rejected, and absolute paths are remapped into the workspace. Use fs_search with mode: "ls" to discover what exists.
file_read Tool
Schema Fields
| Field | Type | Required | Description |
|---|---|---|---|
| file_path | string | Yes | Path to the file to read |
| offset | int | No | Line number to start from, 0-indexed (default: 0) |
| limit | int | No | Maximum lines to read (default: 2000, max: 10000) |
Examples
Read a file:
{"file_path": "/path/to/file.py"}
Read with pagination:
{"file_path": "/path/to/large_file.py", "offset": 100, "limit": 50}
Response Format
{
"content": "line one\nline two\n...",
"line_count": 2,
"file_path": "/path/to/file.py"
}
Guidelines
- Use offset/limit for large files instead of reading everything
contentis the selected text slice, without added line numbers; text line endings are normalized to LFline_countcounts the lines in the returned slice, not the whole filefile_pathis the normalized virtual path inside the workflow workspace- Non-UTF-8 files are returned as base64 text in
content; the tool result does not include a separateencodingfield, and line pagination is not applied to that base64 representation
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-read-skill is a skill published in the GitHub repository zeenie-ai/OpenCompany (880 stars, last pushed yesterday), licensed MIT. It adds 15 tokens to every session and 455 once invoked, about $0.0001 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.
