summarize

A file-reading tool that explains a source file’s purpose, defined parts, imported modules, external packages, and line count.

In plain words
What is it for?
Onboarding to a codebase, documenting files, checking dependencies, and preparing a focused code review.
Why use it?
It gives developers a quick understanding of an unfamiliar file without having to trace every detail themselves.

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

summarize 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.

What it actually says

File Summary

Steps

  1. Read the target file using read_file.
  2. Count the lines of code:
    wc -l <filepath>
    
  3. Identify imports and external dependencies.
  4. Produce a summary with:
    • Purpose: What the file does (1-2 sentences)
    • Key components: Classes, functions, or constants defined
    • Dependencies: External packages and internal modules imported
    • Lines of code: Total count
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.

summarize is a skill published in the GitHub repository key4ng/lite-cc (4 stars, last pushed 5mo ago), licensed MIT. It adds 23 tokens to every session and 136 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 2026-08-31.
