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 | $0.00066 | $0.01431 |
| Opus 5 | $0.00033 | $0.00715 |
| Sonnet 5 | $0.00013 | $0.00286 |
| Haiku 4.5 | $0.00007 | $0.00143 |
Grade A, and why
web-diff-review 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 — 138 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Web Diff Review
Use this skill when a diff should be reviewed in difit.
This single skill covers both common difit workflows:
- ask the user to review current changes or a specific diff in difit
- review the diff first, then launch difit with findings or explanations preloaded as inline comments
Pick The difit Command First
Before running commands, choose <difit-command> using this rule:
- If
command -v difitsucceeds, usedifit. - Otherwise, use
npx difit. - If falling back to
npx difitwould require network access in a sandboxed environment without network permission, request the required approval first.
Decide Which Review Mode Fits
Choose one of these modes:
-
user-review modeUse this when the goal is to hand the diff to the user for review after code changes. -
preloaded-review modeUse this when the user wants review findings, code explanations, or guided comments already attached inside difit.
Defaulting rules:
- If the user asks to review, audit, explain, or highlight issues in a diff or PR, default to
preloaded-review mode. - If the user only wants to open, show, or share the diff as a review surface, default to
user-review mode. - If there are no concrete findings worth attaching to lines, prefer
user-review modeeven when the request sounds review-oriented.
Choose The Diff Target
Use the smallest truthful diff target for the request.
Common launch forms:
- review uncommitted changes:
<difit-command> . - review the HEAD commit:
<difit-command> - review staged changes:
<difit-command> staged - review unstaged changes only:
<difit-command> working - review a specific commit:
<difit-command> <target> - compare two commits or branches:
<difit-command> <target> [compare-with] - review a GitHub PR URL:
<difit-command> --pr <url> - pass stdin diff input:
diff -u file1.txt file2.txt | <difit-command> - force stdin mode explicitly when needed:
diff -u file1.txt file2.txt | <difit-command> -
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
