PR Lens is a tool that turns a pull request into animated diagrams showing the software components it affects and the data flowing between them. Developers use it through GitHub, a command-line interface, or a coding agent to understand changes before reviewing code. The catalogue entries provide instructions and skills for using PR Lens with coding agents.
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 5.1 | $0.00105 | $0.02192 |
| Opus 5 | $0.00053 | $0.01096 |
| Sonnet 5 | $0.00021 | $0.00438 |
| Haiku 4.5 | $0.00011 | $0.00219 |
Grade A, and why
eli5 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 today.
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 — 75 lines — stays where its author put it; the contents beside it link to each section on GitHub.
eli5
Explain like I'm someone who knows nothing about this code: one sentence, then one part at a time, until the whole picture is on screen and the reader already knows every part of it.
A reader who knows nothing cannot take in a diagram. They can take in two boxes and an arrow. So the canvas starts with two boxes and grows. The whole picture is the last thing they see, not the first, and by then it holds nothing new.
You write one graph document. Its views are the growing pictures, its walkthrough plays them in order, and PR Lens draws them. The reader opens a link and presses play. There is no page, no list, no paragraph.
What you need
The PR Lens skill, installed beside this one. If pr-lens/SKILL.md is not there: npx skills add coldteadotai/pr-lens --skill pr-lens. Read its SKILL.md and references/graph-document.md before your first document. Its rules hold here except where this page marks an Override.
Operating manual
-
Write the answer first. Read the code until you can say what it does for a person, in under 48 characters, because the sentence is also a walkthrough heading and a heading stops at 48. Count them.
- For a feature or a command: "When you ___, this code ___." Example: "When you hit send, it emails everyone."
- For a whole codebase: what the product is for. Example: "BestRegards sends newsletters for you." The sentence is about the product, not one path through it.
Override, summary. The sentence is also the document
summary. The reference wants a paragraph about a change; eli5 wants this sentence.
-
Cut to the path. For a feature, trace the one path input takes to output. For a whole codebase, first list the 3 to 5 things a person does with the product, then trace the path of the main one: the thing the product is named after or sold on, or the one with the most code on it. The parts on that path are the diagram: 4 to 10 nodes, 2 to 5 lanes. Helpers, config, types and tests stay out. When two entry points converge on the same code, draw the point where they meet and name both in its body; do not drop one.
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.

eli5 is a skill published in the GitHub repository coldteadotai/pr-lens (1,076 stars, last pushed yesterday), licensed MIT. It adds 105 tokens to every session and 2,192 once invoked, about $0.0005 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 2026-09-12.
