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 | $0.00000 | $0.00687 |
| Opus 5 | $0.00000 | $0.00344 |
| Sonnet 5 | $0.00000 | $0.00137 |
| Haiku 4.5 | $0.00000 | $0.00069 |
Grade A, and why
index 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 2d 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.
How it starts
The opening of the file, as written. The whole thing — 54 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Command reference
summarize is one binary with a handful of subcommands. The default subcommand is summarize itself — the one you use 99% of the time. The others wrap related tooling.
Subcommands
summarize— main command. Takes a URL, file, or stdin and produces a summary or extracted content.summarize slides— extract scene-change keyframes from a YouTube URL, direct video URL, or local video file into PNGs (and optional OCR text). Standalone version of the--slidesflag.summarize transcriber— set up local ONNX transcription (Parakeet, Canary). Prints the env vars you need.summarize daemon— manage the local HTTP daemon that the Chrome Side Panel talks to. Subcommands:install,restart,status,uninstall,run.summarize refresh-free— scan OpenRouter:freemodels, write working candidates to~/.summarize/config.json.
Output discipline
All subcommands keep the same output discipline — straight from gogcli's playbook so pipes and scripts stay parseable:
- stdout: the result. Plain text, Markdown, JSON, or files (slides only).
- stderr: progress, prompts, warnings, and errors.
--jsonproduces a stable envelope on stdout.--no-colorstrips ANSI;--plainskips ANSI/OSC rendering for Markdown.
Global behavior
These flags apply to almost every subcommand:
| Flag | Purpose |
|---|---|
--json |
Stable JSON envelope on stdout. Disables streaming. |
--no-color |
Strip ANSI escapes from output. |
--theme <name> |
Pick a CLI theme (SUMMARIZE_THEME env var also works). |
--verbose / --debug |
Detailed progress on stderr. |
--metrics off|on|detailed |
Token + timing metrics line. Default on. |
--timeout <duration> |
Cap fetching + LLM calls. Accepts 30, 30s, 2m, 5000ms. |
-V, --version |
Print version and exit. |
--help |
Print rich help with examples. |
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.

index is a command published in the GitHub repository steipete/summarize (6,588 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 687 tokens. 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.
