Token cost

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.

Security

Grade A, and why

file_reader 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 10d 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 Reader Toolbox

Use this skill when the user asks to read or summarize local text-based files. PDFs, Office documents, images, audio, and video are out of scope for this skill and should be handled by their dedicated skills/tools.

Quick Type Check

Use a type probe before reading:

file -b --mime-type "/path/to/file"

If the file is large, avoid dumping the whole content; extract a small, relevant portion and summarize.

Text-Based Files (use read_file)

Preferred for: .txt, .md, .json, .yaml/.yml, .csv/.tsv, .log, .sql, ini, toml, py, js, html, xml source code.

Steps:

  1. Use read_file to fetch content.
  2. Summarize key sections or show the relevant slice requested by the user.
  3. For JSON/YAML, list top-level keys and important fields.
  4. For CSV/TSV, show header + first few rows, then summarize columns.

Large Logs

If the file is huge, use a tail window:

tail -n 200 "/path/to/file.log"

Summarize the last errors/warnings and notable patterns.

Out of Scope

Do not handle the following in this skill (they are covered by other skills):

  • PDF
  • Office (docx/xlsx/pptx)
  • Images
  • Audio/Video

Safety and Behavior

  • Never execute untrusted files.
  • Prefer reading the smallest portion necessary.
  • If a tool is missing, explain the limitation and ask the user for an alternate format.
Changes

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.
